INSTRUCTIONS FOR USE Castroviejo Calipers: This is a reusable device, packaged non-sterile. It is steam sterilizable.
INDICATIONS
Sontec Instruments Castroviejo Calipers are manually operated instruments designed to perform specific functions such as measuring during a TPLO (Tibial Plateau Leveling Osteotomy) and Ophthalmic surgical procedures. Castroviejo Calipers are used for the precise measurement of the structures of the tibial plateau and in ophthalmic procedures measures the eye including cornea and pupils. When closed, they resemble a closed V-shape with very fine distal tips and a horizontal measuring bar at the distal tips. The center of the caliper has a screw-type device to hold the distal tips open or closed, and the box lock area has a large holding screw. When closed, the distal tips should evenly meet and be nick- and burr-free. Inspect them with a magnification device.
Note: Inspection points include ensuring that the distal tips are clean and intact. Check the box lock screw to ensure it is intact and clean. Also check the locking screw area for cleanliness and function and protect the tips when packaging.
CONTRAINDICATION
These instruments should not be used for anything other than their intended use.
Warnings/Precautions:
CAUTION: US Federal Law restricts these devices to sale
by or on the order of a physician, and the device is intended for use only by or under direction of trained surgeons.
CAUTION: These reusable devices are packaged non-sterile and are steam sterilizable
these instruments. End of life is normally determined by wear and damage due to use.
CAUTION: Use of this instrument for any purpose, or in any manner other than those described here may cause instrument damage or failure which could result in serious patient injury or death. If needed, all metal products or fragments thereof can be located by means of an X-Ray. CAUTION: The World Health Organization recommends
the longest exposure times when there is concern regarding HIV, TSE, CJD, etc. contamination. It is the user’s responsibility to determine what contamination exists and what procedure is appropriate to ensure proper sterilization.
WARNING: DO NOT flash sterilize these instruments. The instruments have not been designed for flash sterilization. Discard instruments after suspected Creutzfeldt-Jakob Disease (CJD) exposure – these instruments have not been designed to withstand the chemical and thermal exposures recommended to eradicate prions. Every surgical instrument must be properly inspected, cleaned, lubricated, and sterilized before the initial use and all subsequent uses. Carefully examine each surgical instrument for proper function and damage of any sort prior to and after each use. It is extremely important to check all working parts including blades, locks, points, stops, ratchets, screws, etc. Instruments that show any sign of damage or corrosion should be repaired or replaced prior to further use. Instruments may only be used for their intended purpose in their respective surgical specialties by properly trained and qualified personnel. The surgeon (qualified user) shall be responsible for the proper instrument selection for each application, for obtaining the appropriate training for use, for insuring the proper care and sterilization, and for their operative use. Sontec Instruments, Inc. does not have any control over the ultimate use of the surgical instruments and therefore,
cannot accept any responsibility or liability for any damages caused by inappropriate application and use or by inappropriate sterilization and maintenance of the instruments. Materials Used where applicable: Sontec Instruments are manufactured using either high quality stainless steel, titanium (including titanium alloys), or aluminum unless otherwise stated. These metals are durable and will last for years if properly used and maintained. It is the user’s responsibility to ensure continuous and proper care of the surgical instruments in addition to proper preparation, cleaning, and sterilization. Stainless Steel – Stainless steel provides excellent, but not complete protection from rust and corrosion. The main enemies of stainless steel are organic materials not removed immediately after use, chloride ions, common salts and other contaminants contained in tap water. The use of proper cleaners, disinfectants and distilled water cannot be overemphasized. Titanium – Titanium and titanium alloys are used to make light weight instruments. These instruments can be handled and treated like stainless steel instruments. Titanium instruments are often anodized blue for color identification. Aluminum – Aluminum is also used to make light weight instruments. However, only neutral, non-alkaline cleaners and fully de-mineralized water may be used with aluminum instruments. Tungsten Carbide – Chemical/cold sterilization should never be used for instruments with tungsten carbide inserts/edges. The solutions used are harmful to tungsten carbide. Cleaning and Sterilizing Guidelines: Sontec Instruments, Inc. has no control over the conditions or contaminants the user will subject the instruments to, therefore, it is the ultimate responsibility of the user to determine what cleaning and sterilizing methods and additional steps might be needed to properly remove all known and unknown organisms or contaminants. In all circumstances, the user should closely follow the recommendations provided by the manufacturers of the cleaning/sterilizing products and equipment used.

The following are the essential steps that Sontec Instruments, Inc. recommends: First and Foremost – Never allow organic materials or other contaminants to dry or get encrusted on the instrument. Important – Always process dissimilar metals separately including different grades of the same metals. Do not allow instruments to stand while touching each other.
Manual Cleaning Instructions: Rinse and/or flush under warm flowing tap water to remove visible debris for a minimum of 30 seconds. Ultrasonically clean using a detergent solution prepared according to the manufacturer's Instructions for a minimum of 10 minutes. Completely Immerse the Instruments in a detergent solution prepared according to the manufacturer's instructions.
Always – Wear appropriate safety protection and observe applicable safety procedures when handling, cleaning, and sterilizing surgical instruments.
Scrub all instruments with an appropriately sized soft nylon bristle brush for a minimum of one minute, paying particular attention to crevices and hard to clean areas.
Pre-cleaning/Holding – Thoroughly rinse instruments with warm water immediately after use. If not possible to start cleaning process immediately after use, apply a neutral pH enzymatic solution for holding following the manufacturer’s instructions, and then rinse thoroughly before continuing disinfecting and cleaning. Sontec recommends Ruhof.
Rinse with flowing purified (deionized) water for a minimum of 30 seconds.
Disinfecting – Immerse instruments in a suitable disinfectant approved for use on surgical instruments following the manufacturer’s instructions. Rinse instruments thoroughly after disinfecting. Cleaning – Instruments must be thoroughly cleaned before sterilization and have all organic materials, stains, rust, corrosion, and other contaminants completely removed. Regardless of the cleaning method used, stubborn particles will need to be removed manually by soaking in a suitable enzymatic cleaner following the manufacturer’s instructions and then brushing with a Whisk‘R Brush'. All instruments should be cleaned in the open and/or disassembled position. Most rust, pitting, stains, and corrosion can be removed using a suitable surgical instrument rust and stain remover following the manufacturer’s instructions. Black coated and color anodized components may be negatively affected if aggressive cleaning mediums or appliances (e.g., extreme acidic/alkaline, abrasives) are used. A pH neutral cleaner, which may or may not contain enzymes, (such as pH neutral cleaner Prepzyme or enzymatic cleaner Endozime manufactured by Ruhof) is recommended. Exposure to chlorides or hydrogen peroxide may negatively affect the coating or colorization of components. Ultrasonic or automatic washer using suitable instrument cleaners and following the manufacturer’s instructions is preferred over manual cleaning alone. In all instances care should be taken to always use clean, fresh solutions and finish by thoroughly rinsing the instruments. Instruments should be completely dry before storage.
Dry the instruments using absorbent, low-lint wipes to remove excess water. Automated Cleaning Instructions: Use only washer/disinfector machines that have been validated in accordance with ISO 15883. Perform pre-cleaning to remove gross contaminants as follows: o Submerge and soak in a pH neutral detergent solution prepared according to the manufacturer's instructions for a minimum of 1 minute. o Flush any cannulations that may be present. o While still submerged, remove visible soil by scrubbing with an appropriately sized soft nylon bristle brush d. Rinse with flowing purified (deionized) water for a minimum of 30 seconds. o Load instruments into washer/disinfector in accordance with the manufacturer's instructions. o Arrange Instruments with curved surfaces and cannulations facing downward to prevent pooling of water. Operate the washer/disinfector cycle according to the manufacturer's Instructions. a. Recommended minimal washer/disinfector parameters: o Heated Wash at 140F° (60°C) for 2 minutes
o Heated Tap Water Rinse at 140°F (60°C) for 20 seconds o Heated purified Water Rinse at 180°F (82°C) for 1 minute o Forced Air Drying at 240° F (116°C) for 9 minutes Note: Automated cleaning is not suitable for instruments with long lumens, ball joints, or stainless-steel cables (e.g., suction tubes and surgical arms). Such instruments should undergo a manual cleaning prior to sterilization. o Turn adjustment knob counter-clockwise to loosen prior to autoclave. o Rinse caliper for up to 1 minute with flowing deionized water. o Manually dry caliper using clean, absorbent, low- lint wipes to remove excess water. o Inspection before use: o Inspect entire assembly for damage. o Hold caliper and tighten central adjustment knob clockwise. Lubrication – Thoroughly lubricate all working parts and joints of instruments prior to inspection and sterilization with a lubricant suitable for use on surgical instruments that will withstand the temperature used during sterilization. For instruments with moving parts, lubricate joints with a steampermeable, water-soluble instrument lubricant prior to sterilization. Some lubricants and rust inhibitors may be used during the cleaning process. Sontec recommends Ruhof. Sterilization – The most common method of sterilization is by autoclaving following the autoclave manufacturer’s instructions.
