•
The PSD-30 has been designed for flexible endoscopic applications. Therefore, do not use it for surgical operations.
•
Always use the S-cord when endoscopic treatment is performed with an endoscope equipped with the S-cord connector mount. When using an endoscope without the S-cord connector mount, refer to the instruction manual and confirm that the electrosurgery is feasible with this endoscope. If the electrosurgical unit is used in conjunction with an endoscope that is not feasible with the electrosurgery, a burn to the patient, the operator or the assistant may occur.
•
If the electrosurgical unit fails and the output is stopped during treatment, it may be impossible to continue treatment due to adhesion of the endo-therapy accessory to a mucous tissue or other accident. Prepare a spare electrosurgical unit as backup to ensure that the procedure can be completed without complication in case of a malfunction.
ELECTROSURGICAL UNIT PSD-30
Important Information - Please Read Before Use
•
Always have a defibrillator ready in case of a cardiac emergency. During operation of the defibrillator, remove the endoscope from the patient.
•
To respond to possible patient bleeding, prepare at least the following three hemostatic procedures: coagulation, clipping and local injection.
•
To prepare for possible accidents, emergency equipment for life-saving, intubation and appropriate pharmaceuticals should be located in or near the procedure room.
•
Never attach the patient plate in the vicinity of a metal implant. The tissue in the vicinity of the metal implant may be burned.
•
Keep the electrosurgical unit and ancillary cords (A-cord, P cord, S-cord) as far away as possible from other electromedical equipment and cords. If placed too close, high frequency signals or spark discharge noise from the electrosurgical unit may interfere with the operation of other equipment.
•
To prevent patient burns, the electrosurgical unit and ancillary cords (A-cord, P cord, S-cord) should not come in contact with the patient or metal parts of the operating table. Furthermore, patients should also keep away from metallic parts of the operating table or other devices.
•
Never loop the cords (A-cord, P cord, S-cord) or bundle cords together with cords belonging to other medical equipment. The high frequency signals or spark discharge noise generated by the electrosurgical unit may interfere with the operation of other medical equipment.
•
The electrosurgical unit may interfere with electromedical equipment used in conjunction with it. Before use, thoroughly confirm the compatibility of all the equipment.
•
Do not bring the tip of the electrosurgical accessory close to a metal clip or other accessories. The tissue around the metal clip or the accessory may be burned.
•
To prevent electric shock, the electrosurgical unit is designed to function with insulated connectors that have Type CF electromedical equipment classifications (A-cord, P cord, P plate, S-cord). Therefore, to prevent shock caused by leakage current from other electrical equipment applied to the patient, the connectors from the other equipment should not be grounded.

•
Should any abnormal output be suspected during operation, immediately terminate the use of the equipment and turn OFF the electrosurgical unit.
•
To prevent operator shock, electrosurgical unit malfunction and electrosurgical unit damage, keep liquids away from all electrical equipment. If liquid gets on or into the electrosurgical unit, terminate operation immediately and contact Olympus.
•
To prevent patient burns, the patient’s skin surfaces should not touch each other (e.g. bare arm and side of chest) or any metal items in the procedure room. Remove any metallic items from the patient (wristwatches, jewelry, etc.) before starting the procedure.
•
To prevent patient burns, the patient’s clothes must be dry.
•
To prevent operator and assistant burns, be sure to wear chemical-resistant gloves during operation.
•
If the intestines contain a flammable gas, replace this gas with air or a non-flammable gas before performing the operation, to minimize the risk of fire or explosion.
•
The endoscopic treatment performed should not include a therapy with which part of the treated tissue (poly head, etc.) or part of the endoscope distal end or endo-therapy accessory is in contact with or close to normal tissue. Otherwise, current flows to the normal tissue through the part of the treated tissue, the metallic parts at the endoscope’s distal end or endo-therapy accessory and may cause burns.
•
Be sure that the distal end of endoscope or accessory does not contact bridging fluids surrounding the target tissue. Electric current may flow to the surrounding normal tissue via the fluids and cause burns.
•
Never grasp the target tissue with non-insulated grasping forceps. Non-insulated grasping forceps will disperse the electric current and normal operation may be impeded.
•
To ensure electrical safety, the electrosurgical unit should not be used in conjunction with: − Electrical equipment whose safety against leakage current is not guaranteed. − Electrosurgical equipment whose safety in combined use is not guaranteed.

•
If the electrosurgical unit is used in conjunction with a non-Olympus electrosurgical unit, keep the electrosurgical accessory away from the target area while the electrosurgical unit is in operation. Do not activate output of both units simultaneously. Patient or operator injury may occur due to the concentration of electric current.
•
When using an electrocardiograph or other physiological monitoring equipment simultaneously with the electrosurgical unit on a patient, any monitoring electrodes should be placed as faraway as possible from the electrodes and patient plate used with the electrosurgical unit. If placed too close, high frequency signals or spark discharge noise from the electrosurgical unit may interfere with the operation of an electrocardiograph or other physiological monitoring equipment. Needle monitoring electrodes should not be used, as they may cause patient burns. Physiological monitoring equipment incorporating high frequency current limiting devices is recommended.
•
Use physiological monitoring equipment throughout the entire procedure, for continuous observation of the patient’s condition.
•
The open-circuit voltage output characteristics of the electrosurgical unit are shown below. When setting the output level, first set it to a low output level and increase it gradually. If the output is initially set to an excessive level, the electrode’s insulation could be damaged, which could cause operator and/or patient burns. Furthermore, it is recommended that you perform basic experiments before using the electrosurgical unit. If the instruction manual for the endoscopic accessory to be used stipulates a rated voltage, the output should be set so that it does not exceed that voltage.
