1. Important Information – Please Read Before Use! Read this Instructions for Use (IFU) carefully before using the aScope™ Duodeno and keep for future reference. Failure to read and thoroughly understand the information presented in this IFU, as well as those developed for ancillary endoscopic equipment and accessories, may result in serious injury to the patient and/or user. Furthermore, failure to follow the instructions in this IFU may result in damage to, and/or malfunction of the equipment. This IFU describes the recommended procedures for inspecting and preparing the system prior to its use. It does not describe how an actual procedure is to be performed, nor does it attempt to teach the beginner the proper technique or any medical aspects regarding the use of the equipment. It is the responsibility of each medical facility to ensure that only appropriately trained personnel, who are competent and knowledgeable about endoscopic equipment, antimicrobial agents/processes and hospital infection control protocol, are involved in the use, handling and care of these medical devices. The IFU may be updated without further notice. Copies of the latest version are available upon request.
1.1. Intended Use / Indication for Use The aScope™ Duodeno is designed to be used with the aBox™ Duodeno, endoscopic accessories (e.g. biopsy forceps) and other ancillary equipment (e.g. medical grade video monitor) for endoscopy and endoscopic surgery within the duodenum. Note: Do not use this device for any purpose other than its intended use. Select the endoscope to be used according to the objective of the intended procedure based on the full understanding of the endoscope’s specifications and functionality as described in this IFU.
1.2. General Information The device is intended to be used by physicians trained on ERCP procedures. If there are official standards for user qualifications to perform endoscopy and endoscopic treatment that are defined by the hospital´s medical administrators or other official institutions, such as academic societies on endoscopy, follow those standards. If there are no official qualification standards, the operator of this device must be a physician approved by the medical safety manager of the hospital or person in charge of the department (department of internal medicine, etc.). The physician should be capable of safely performing the planned endoscopy and endoscopic treatment following guidelines set by the academic societies on endoscopy, etc., and considering the difficulty of endoscopy and endoscopic treatment. This manual does not explain or discuss endoscopic procedures. Additional equipment connected to medical electrical equipment must comply with the respective IEC or ISO standards (e.g. IEC 60950 or IEC 62368 for data processing equipment). Furthermore, all configurations shall comply with the requirements for medical electrical systems (see clause 16 of the latest valid version of IEC 60601-1). Anybody connecting additional equipment to medical electrical equipment configures a medical system and is therefore responsible that the system complies with the requirements for medical electrical systems. If in doubt, consult your local representative or contact Ambu for support.
1.3. Contraindications Contraindications for ERCP include the following: • Patients under 18 years. • When the risks to patient health or life are judged to outweigh the most favorable benefits of the procedure. • When adequate patient cooperation or consent cannot be obtained. • When a perforated viscus is known or suspected. Additional contraindications could exist for high risk procedures, such as biliary sphincterotomy

EN
in a patient who is fully anticoagulated or therapeutically dosed anti-platelet agents. Following conditions may as well contraindicate ERCP and need to be qualified: • Patient has suffered a prior severe allergic reaction to ERCP contrast medium. • Unstable cardiopulmonary, neurologic or cardiovascular status of the patient. • Severe uncorrected coagulopathy.
1.4. Clinical Benefits Single-use application minimises the risk of cross-contamination of the patient.
1.5. Warnings and Cautions Failure to observe these warnings and cautions may result in patient injury or damage to the equipment. Ambu is not responsible for any damage to the system or patient injury resulting from incorrect use.
WARNINGS Indicate a potentially hazardous situation which, if not avoided, could result in death or serious injury. Connection of Devices • Do not connect non-medical grade devices to the endoscope. Connection of devices that are not medical grade (IEC 60601 conform) could have negative impact on the safety of the system. Connect only medical grade equipment to the endoscope. For detailed information consult the IFU of the aBox™ Duodeno. Single-Use & Cross-Contamination • The endoscope described in this IFU is a single-use medical device. Since it is provided in sterile packaging, it must be properly handled (by using aseptic technique) and stored to ensure the sterile packaging is not breached prior to use. • Do not attempt to clean and reuse the aScope™ Duodeno as it is a single-use device and cannot be reprocessed. Reuse of the product can cause contamination, leading to infections as well as a malfunction of the device. • Do not use the aScope™ Duodeno if the product sterilization barrier or its packaging is damaged. • A new bottle of sterile water with at least 1.000 ml in volume should be used for each procedure. Using an opened bottle of water may lead to cross-contamination or infection. • To guard against dangerous chemicals and potentially infectious material during the procedure and danger of unintentional diathermy burns, wear personal protective equipment, such as eyewear, face mask, moisture-resistant clothing, and chemical and electrical-resistant gloves that fit properly and are long enough so that your skin is not exposed. Please note that a new pair of gloves is required prior to each procedure. Preparation for Use • Before endoscopy, remove any metallic objects (watch, glasses, necklace, etc.) from the patient. Performing high-frequency cauterization treatment while the patient is wearing metallic objects may cause burns on the patient in areas around the metallic objects. • Using an endoscope that is not functioning properly or is suspected to be defective may compromise patient or operator safety and could potentially result in severe equipment damage. Inspect the endoscope for damages prior to use. Check the functionality of the endoscope prior to use. Be sure to always have another endoscope available and ready for use to avoid any unnecessary delays due to equipment failure or malfunction.

Operator Instructions • Do not strike, hit, or drop the endoscope’s distal end, insertion tube, bending section, control section, umbilicus, and/or endoscope connector. Also, do not bend, pull, or twist the endoscope’s distal end, insertion tube, bending section, control section, umbilicus, or endoscope connector with excessive force. The endoscope may be damaged and could cause patient injury, burns, bleeding, and/or perforations. It could also cause parts of the endoscope to fall off inside the patient. • Do not stare directly into the distal end of the endoscope and avoid patient eye contact with the distal end of the endoscope whilst the LEDs are ON. Keep your eyes away from the distal end when inserting endoscopic accessories as eye injury could potentially result. • No modification of this equipment is allowed. • Do not leave the endoscope illuminated before and after examination. Otherwise, the LEDs could be directed toward to the opened eyes of the sedated patient and can cause retina burns. Ancillary Equipment • If combinations of ancillary equipment other than those described in this IFU are used, full responsibility is assumed by the medical treatment facility. • A defective vacuum pump could lead to loss of cooling and increased temperature at the tip of the endoscope. Make sure to have another vacuum source available. Operation of the Endoscope • Never perform angulation control forcibly or abruptly. Never forcefully pull, twist, or rotate the angulated bending section. Patient injury, bleeding, and/or perforation may result. It may also become impossible to straighten the bending section during an examination. Never operate the bending section, feed air or perform suction, insert or withdraw the endoscope’s insertion section, or use endoscopic accessories without viewing the live endoscopic image or when the image is frozen or magnified. Patient injury, bleeding, and/or perforation may result. • Never insert, withdraw or operate the insertion section abruptly or with excessive force. Patient injury, bleeding, and/or perforation may result. • Never insert or withdraw the endoscope’s insertion section while the bending section is bent or locked in position. Patient injury, bleeding, and/or perforation may result. • Never insert or withdraw the endoscope while the elevator is raised, or when endoscopic accessory extends from the distal end of the endoscope. Otherwise, patient injury, bleeding, and/or perforation can result. • Firmly connect the suction tube to the suction pump and to the suction connector on the endoscope. If the suction tube is not attached properly, debris may drip from the tube and can pose an infection control risk, cause equipment damage, and/or reduce suction capability. • If the sterile water level in the water bottle is too low, replace the bottle with a new one. An empty bottle can cause loss of rinsing and cooling function. Always keep a new bottle of sterile water ready for this case. • If blood unexpectedly adheres to the surface of the insertion section of the withdrawn endoscope, carefully check the condition of the patient. • Do not use the endoscope if any parts of the endoscope or endoscopic accessory fall off inside the patient body due to equipment damage or failure. Stop using the endoscope immediately and retrieve all parts in an appropriate way, otherwise, serious patient injury may occur.
6
EN Image Always check whether the image on the screen is a live image or a recorded image and verify that the orientation of the image is as expected. Do not use this device if the live image cannot be observed, otherwise, patient injury may occur. • Always set the intensity of electrosurgical devices to the lowest required value to avoid image disturbance. Do not increase the level of intensity above the standard ERCP settings. Always limit the continuous activation time of electrical devices to a minimum. • If an abnormal endoscopic image appears or an abnormal function occurs but quickly corrects itself, the endoscope may have malfunctioned. In this case, consider abandoning the procedure because the irregularity can occur again, and the endoscope may not return to its normal condition. Stop the examination immediately and slowly withdraw the endoscope while viewing the endoscopic image. Otherwise, patient injury, bleeding, and/or perforation can result. Over-insufflation & Gas • Confirm that the top hole of the insufflation/rinsing valve is not blocked. If the hole is blocked, air is fed continuously and patient pain, bleeding, and/or perforation can result. • Do not inflate air or a nonflammable gas excessively into the patient. This could cause gas embolism and/or over-insufflation. • Do not insufflate flammable gas into the patient. Otherwise, patient injury may occur. Distal-end Temperature • The temperature of the distal end of the endoscope may exceed 41 ˚C (106 ˚F) and reach 50 ˚C (122 ˚F) due to intense endoscopic illumination. Therefore, do not leave the endoscope illuminated before and/or after an examination and always maintain a suitable distance necessary for adequate viewing while using the minimum level of illumination for the minimum amount of time. Continued illumination will cause the distal end of the endoscope to become hot and cause operator and/or patient burns. • Avoid long periods of contact between the tip of the device and the mucosal membrane, sustained contact with the mucosal membrane may cause mucosal injury. The distal end of the endoscope may get warm due to heating from the light emitting part. When withdrawing the endoscope, the distal end should be in the neutral and non-deflected position with the brakes released. Biopsy Valve • Before using a syringe to inject liquid through the biopsy valve or when aspirating, detach the valve’s cap from the main body. If the cap is not detached and/or the syringe is not inserted straight, the biopsy valve could be damaged. This could reduce the efficacy of the endoscope’s suction system, and may leak or spray patient debris or fluids, posing an infection control risk. If the biopsy valve is left uncapped during the procedure, debris or fluids could leak or spray from it, posing an infection control risk. When the valve is uncapped, place a piece of sterile gauze over it to prevent leakage. • Patient debris might spray when endoscopic accessories are withdrawn from the biopsy valve. To prevent this, hold a piece of gauze around the accessory and the biopsy valve during withdrawal. • Do not let the endoscopic accessory hang down from the biopsy valve. This can damage the valve, which can reduce the efficacy of the endoscope’s suction system and may leak or spray patient debris or fluids, posing an infection control risk. • Do not use the biopsy valve if any irregularities are observed during the inspection. An irregular, abnormal, or damaged valve can reduce the efficacy of the endoscope’s suction system, and may leak or spray patient debris or fluids, posing an infection control risk. Replace with a new one if necessary.
7
Endoscopic Accessories • When using endoscopic accessories, make sure the accessory remains visible in the endoscopic image. If the position of the accessory cannot be seen in the endoscopic image, serious patient injury and/or equipment damage may occur. • When inserting or withdrawing an endoscopic accessory, confirm that its distal end is closed or completely retracted into the sheath. Make sure to straighten the bending section as much as possible. Inserting or withdrawing endoscopic accessories with excessive force may damage the working channel or the endoscopic accessories. Slowly insert or withdraw the endoscopic accessory straight into or from the slit of the biopsy valve. Otherwise, the biopsy valve may be damaged and pieces of it could fall off and/or cause patient injury. • Do not insert endoscopic accessories without the elevator being raised. If they are inserted without the elevator being raised, the accessory cannot be observed in the endoscopic image and may cause patient injury. • Check the movement of the endoscopic accessory by slowly operating the elevator control lever several times to raise the elevator. Otherwise, the endoscopic accessory may move in unexpected directions, and patient injury, bleeding, and/or perforation may result. • Locate the endoscopic accessories as central as possible in the endoscopic image by adjusting the position of the distal end of the endoscope, particularly while performing papillotomy. When the distal end of the endoscopic accessory is positioned in the left or right side of the endoscopic image, and the elevator control lever is operated, the endoscopic accessory may move abruptly, resulting in patient injury, bleeding, and/or perforation. • Do not use excessive force when operating, inserting or withdrawing endoscopic accessories and make sure the accessory is visible on the endoscopic image. Otherwise, the endoscopic accessory may extend from the distal end of the endoscope abruptly, which could cause patient injury, bleeding, and/or perforation. Never emit high-frequency current before confirming that the distal end of the high-frequency endoscopic accessory is in the endoscope’s field of view. Also, confirm that the electrode section and the mucous membrane in the vicinity of the target area are at an appropriate distance from the distal end of the endoscope. If the high-frequency current is emitted while the distal end of the endoscopic accessory is not visible or too close to the distal end of the endoscope, patient injury, bleeding, and/or perforation as well as equipment damage can result. • While moving the elevator, do not open or close the distal end of the endoscopic accessory. This could damage the endoscopic accessory and could cause patient injury, bleeding, and/or perforation. If the endoscopic accessory cannot be inserted or withdrawn, the distal end of the endoscopic accessory cannot be opened or closed, move the elevator control lever in the opposite direction of the "Up" direction to lower the elevator. • When the device is used with energized endoscopic devices, leakage current may be additive. Use only endoscopic devices of type BF or CF. Check the compatibility of the accessory/endoscopic device before use regarding any criteria for safe use. Suction • Avoid aspirating solid matter or thick fluids; working channel, suction channel, or suction valve clogging can occur. • When aspirating, maintain the suction pressure at the lowest level necessary to perform the procedure. Excessive suction pressure could cause aspiration of and/or injury to the mucous membrane. In addition, patient fluids could leak or spray from the biopsy valve, posing an infection control risk.

Unpacking and Placing the Endoscope • Do not use a knife or another sharp instrument to open the pouch or cardboard box. • Place the aScope™ Duodeno on a level surface while unpacking. Dropping the aScope™ Duodeno could damage it. Prior to Use • To prevent the patient from biting the endoscope, it is recommended that a mouthpiece is placed in the patient’s mouth before inserting the endoscope. • Never use a mouthpiece that is deformed, damaged or shows other irregularities, otherwise, patient injury and/or equipment damage may occur. • To prevent the patient from breaking one or more teeth, make sure there are no teeth that are not permanently capped or no missing teeth, prior to examination. • To prevent the patient of losing a dental prosthesis, make sure the patient removes it prior to examination. • Do not allow the suction canister to fill completely. The suction canister must be changed after each examination. Using a filled suction canister may lead to loss of the suction function, loss of cooling or malfunction of the suction pump. Operating the Endoscope • Be careful not to damage the insertion tube or distal end when using sharp devices in combination with the aScope™ Duodeno. The endoscope connector will disconnect from the endoscope connector socket on the aBox Duodeno and the endoscopic image will be lost. • Be careful when handling the distal end of the insertion tube and do not allow it to strike other objects, as this may result in damage to the equipment. The lens surface at the distal end is fragile and visual distortion may occur. • Do not coil the insertion tube or the umbilicus in a diameter of less than 12 cm. Equipment damage may result if so. • Do not attempt to bend the endoscope’s insertion section with excessive force. Otherwise, the insertion section may be damaged. • Do not twist or bend the bending section with your hands. Equipment damage may result if so. • The endoscope's suction valve and insufflation/rinsing valve cannot be removed from the control section. Pressing, pulling, or twisting them with excessive force can break the switches and/or cause water leaks. • The endoscope’s insufflation and rinsing valves cannot be removed from the control section. Pressing, pulling, or twisting them with excessive force can break the switches and/or valves which will lead to loss of functionality.

4. Preparation for Use Numbers in gray circles below refer to illustrations on page 2. Before each procedure, prepare and inspect a new endoscope as instructed below. Inspect other equipment to be used with this endoscope as instructed in their respective instruction manuals. Should any irregularity be observed after inspection, follow the instructions as described in section 8, “Troubleshooting”. If this endoscope malfunctions, do not use it. Contact your Ambu sales representative for further assistance.
4.1. Preparation and Inspection of the aScope™ Duodeno Inspection of the Endoscope 1 • Check that the pouch seal is intact. 1a • Carefully peel of the peel pouch packaging of the aScope™ Duodeno packaging and remove the protective elements from the handle and the distal end. 1b • Carefully run your hand back and forth over the entire length of the insertion tube, including the bending section and distal end, of the aScope™ Duodeno to make sure that there are no impurities or damages on the endoscope, such as rough surfaces, sharp edges or protrusions which may harm the patient. Make sure to use aseptic technique when performing the steps above. Otherwise, the sterility of the product will be compromised. 1b • Inspect the distal end of the endoscope´s insertion section for scratches, cracks or other irregularities. 1b • Turn the Up-Down and Right-Left control wheels in each direction until they stop and return to neutral position. Confirm that the bending section functions smoothly and correctly, that maximum angulation can be achieved and returned to neutral position. 1c • Operate the elevator control lever to confirm that the elevator can be operated smoothly and correctly and can be returned to neutral position. 1d 14
• • •
Confirm that the angulation locks are functional by locking and releasing the angulation locks according to section 2.3. Turn the angulation wheels fully in all directions, lock the angulation in a fully angulated position and confirm that the bending section can be stabilized. Release the angulation locks and confirm that the bending section straightens out. Confirm that the top hole of the insufflation/rinsing valve is not blocked. 1e Using a syringe, insert sterile water into the working channel. Press the plunger, ensure that there are no leaks and that the water is emitted from the distal end. 1e If applicable, confirm compatibility with applicable accessory devices as appropriate. 2
4.2. Preparation of the Endoscope Prepare and inspect aBox™ Duodeno, medical grade monitor, suction pump, and insufflator as described in their respective manuals. • Prepare a bottle of sterile water and place it in the designed bottle holder located on the front (left side) of the aBox™ Duodeno. For lens washing water it is recommended that the sterile water bottle chosen should contain a minimum of 1000 ml in volume. Please note that a new bottle of sterile water should be used for each procedure. 3 • Power up the aBox™ Duodeno. Once the aBox™ Duodeno has been set and powered up, the system indicates when it is ready by displaying the settings and information menu and the following information message: “please connect endoscope”. 4 For detailed information about powering up the aBox™ Duodeno please refer to the IFU of the aBox™ Duodeno. • Slide the endoscope strain relief into the aBox™ Duodeno connector snap. 5a • Open the housing of the peristaltic pump located on the front panel of the aBox™ Duodeno by gently pushing up the lid with your thumb(s) until the top of the peristaltic pump is exposed. • Carefully place the rinsing tubing of the aScope™ Duodeno around the roller of the peristaltic pump making sure the tubing is not twisted. The rinsing tubing should cover the roller of the pump and go underneath the roller pump. 5b • Close the peristaltic pump by pressing the lid of the housing down until the housing of the peristaltic pump is closed. Make sure that the rinsing tubing is nestled within the notches on each side of the roller before closing completely. 5c • Remove all seal caps/covers from the bottle of sterile water. Insert the process water tubing into the bottle of sterile water. Ensure that the end of the tubing reaches to the bottom of the water bottle so that the maximum volume of water can be suctioned from the water bottle prior to replacing (as necessary) to reduce waste. 5d
4.3. Attaching Ancillary Equipment to the Endoscope The aScope™ Duodeno is designed to work with most readily available and most often utilized medical suction and fluid management systems. Irrespective of the chosen fluid management system, overflow protection must be a feature of the suction canister assembly utilized in order to prevent fluids from entering the system. This feature is commonly referred to as "self-sealing" feature or "shut-off-filter", or similar mechanism. Please note that a new suction canister and connection should be used for each procedure. The aScope™ Duodeno does not itself produce negative pressure and therefore an external vacuum source (e.g. wall suction or medical grade suction pump) is required to operate the system. Standard suction tubings with a nominal diameter should be sufficient, as long as they simply and securely fit over the standard size suction connector of the aScope™ Duodeno. Nomenclature used in this section follows the established convention that each canister utilized has multiple connection ports labelled either "To Vacuum" or "To Patient". However, it is the responsibility of the user to follow all manufacturer instructions and guidance applicable to the endoscopic fluid management system chosen for use with the aScope™ Duodeno. 15
EN
•
Connection to Fluid Canisters 6 To perform patient examinations or procedures, all fluid containers (e.g. sterile water bottle) must be properly and securely connected to the aBox™ Duodeno to prevent spillage, thereby maintaining a safe work environment. Place the containers in the designated locations and connect them according to the instructions in this chapter. Please note, that a new suction canister/sterile water bottle must be used for each procedure. CO₂ Connection/ Connection to the Insufflation System 6 The aScope™ Duodeno is designed to work with a source of medical grade CO₂ for insufflation. The maximum medical grade CO₂ supply pressure is 12 psi (80 kPa). Connect to the aScope™ Duodeno using a tube with a luer-lock connector. • If ancillary equipment is ON, turn OFF. • Connect the luer-lock of the insufflation tubing from the insufflator to the insufflation connector of the aScope™ Duodeno. • Turn the ancillary equipment back ON. Connection to the Suction System 6 Regardless of the vacuum source chosen, the aScope™ Duodeno will require a source to provide a vacuum of min. -7 psi (-50 kPa) and max. -11 psi (-76 kPa) for the endoscope to operate normally. Failure to provide the minimum vacuum requirements could result in a decreased capacity in removing patient waste and/or irrigation fluid and loss of the cooling function. • If ancillary equipment is ON, turn OFF. • Fit the end of the suction tubing securely over the suction connector located on the endoscope connector of the aScope™ Duodeno. • Connect the other end of the suction tubing to the external suction system (e.g. wall suction or medical suction pump). • Turn the ancillary equipment back ON. Electrical Connection to the aBox™ Duodeno 7 • Make sure all components as described above have been connected, the ancillary devices and the aBox™ Duodeno has been set and powered up. • The aBox™ Duodeno indicates when it is ready by displaying the information message on the main monitor screen: “please connect endoscope”.

Check of the Remote Switches All remote switches should be checked to work normally even if they are not expected to be used. The endoscopic image may freeze or other irregularities may occur during examination and may cause patient injury, bleeding, and/or perforation. • Press every remote switch and confirm that the specified functions work as expected. Check of the endoscope's suction, rinsing and insufflation functionality • Check that the suction and rinsing/insufflation valve work as expected by pressing both the suction and rinsing/insufflation valve. Cover the opening of the rinsing / insufflation valve and confirm that the corresponding function works properly.
4.4. Operating the aScope™ Duodeno Insertion of the Endoscope 9 • Insert a suitable mouthpiece and place it between the patient's teeth or gums. • Make sure the elevator is not raised before you insert the endoscope. • If necessary, apply a medical-grade lubricant to the insertion section. • Insert the distal end of the endoscope through the opening of the mouthpiece, then from the mouth to the pharynx while viewing the endoscopic image. Do not insert the insertion section into the mouth beyond the insertion section limit mark. Holding and Manipulation of the endoscope • The control section of the endoscope is designed to be held in the left hand. • The insufflation/rinsing and suction valves can be operated using the left index finger. • The UP/DOWN angulation control wheel and the elevator control lever can be operated using the left thumb of the left hand. • The right hand is free to manipulate the insertion section and the RIGHT/LEFT angulation control wheel. Angulation of the Distal End • Operate the angulation control wheels as necessary to guide the distal end for insertion and observation. • The endoscope’s angulation locking levers are used to hold the angulated distal end in position. Insufflation/Rinsing • Cover the insufflation/rinsing valve’s hole to feed air from the insufflation/rinsing valves to the distal end. Press the insufflation/rinsing valve to feed water onto the objective lens. Instillation of Fluids • Fluids can be instilled through the working channel by inserting a fluid-filled syringe into the working channel port of the aScope™ Duodeno. Insert the syringe completely into the working channel port and press the plunger to instill fluid. • Make sure you do not apply suction during this process, as this will direct the instilled fluids into the suction collection system. To ensure that all fluids have left the channel, flush the channel with ca. 5 seconds of air. Suction • Press the suction valve to aspirate excess fluids or other debris obscuring the endoscopic image. • For optimal suction capability, it is recommended to remove accessories entirely prior to suction. Insertion of Endoscopic Accessories Always make sure to select the correct size endoscopic accessory for the aScope™ Duodeno. 17
Inspect the endoscopic accessory before using it. If there is any irregularity in its operation or external appearance, replace it. Insert the endoscopic accessory into the working channel port and advance it carefully through the working channel until it can be seen on the monitor. • Select the endoscopic accessories compatible with the aScope™ Duodeno. Refer to the accessories' instruction manuals for operating instructions. • Raise the elevator by moving the elevator control lever in the “Up” direction. • Hold the UP/DOWN and RIGHT/LEFT angulation wheels stationary. • Confirm that the tip of the endoscopic accessory is closed or retracted into its sheath and insert the endoscopic accessory slowly and straight into the biopsy valve. • Hold the endoscopic accessory approximately 4 cm from the biopsy valve and advance it slowly and straight into the biopsy valve using short strokes while observing the endoscopic image. Confirm that the tip of the endoscopic accessory contacts the elevator. • Move the elevator control lever in the opposite direction of the "Up" direction to lower the elevator. Advance the endoscopic accessory slightly and move the elevator control lever in the “Up” direction. Confirm that the accessory appears in the endoscopic image. • Manipulate the elevator control lever to adjust the height of the elevator. Withdrawal of Endoscopic Accessories • Close the tip of the endoscopic accessory and/or retract it into its sheath. 10 • While lowering the elevator gradually, slowly withdraw the endoscopic accessory. Withdrawal of the Endoscope • Stop using the image magnification (zoom) function of the aBox™ Duodeno. • Move the elevator control lever in the opposite direction of the "Up" direction until it stops. • Aspirate accumulated air, blood, mucus or other debris by depressing the suction valve. • Move the Up/Down locking lever to the "Down" direction to release the angulation. • Turn the Left/Right locking lever to the “F” direction to release the angulation. • Carefully withdraw the endoscope while observing the endoscopic image. Remove the mouthpiece from the patient´s mouth.
