How to Clean and Sterilize Laparoscopc Hand Instruments


1.CLEANING

 

 Immediately after each use and to prevent residual proteins from drying on instruments, instruments should be fully immersed in appropriate neutral-pH cleaning and disinfection solution recommended for reprocessing of laparoscopic surgical instruments.  Closely follow the cleaning and disinfectant manufacturer instructions for chemical concentration and immersion time recommendations. Plain water washing is not considered adequate. It is recommended that fresh solutions be used every day. Higher concentration and prolonged immersion time may cause corrosion or other damage to the instruments. Always avoid overnight or weekend holding or soaking.

 

Manual Disinfection and Cleaning:

 

For Manual Disinfection and Cleaning, use a soft nylon brush to gently remove any exterior dirt and debris. Instruments are equipped with a lock. Connection which should be opened and force flushed using the appropriate equipment and pressure flushing system. A water jet gun should be used on the jaw, joints, handles and the inside of sheaths. After cleaning and disinfection, the instruments should be thoroughly rinsed, both on the exterior and interior sheath, with distilled water. Immediately dry instruments to prevent corrosion. Drying can be performed manually, but a compressed air pistol is recommended for more delicate instruments and is more effective for overall drying.

 

Thoroughly inspect instruments for effective cleaning(free from any visible dirt and residue). Also inspect the instruments for any damaged, worn, corroded, pitted / porous conditions and ensure proper function. Contact Geyi if any damage is observed and if repair is necessary. Apply non-silicone instrument lubricant to the joints and jaws of the instrument to ensure easy movement. Caution: Do not oil electrical connections on instruments.

 

Instruments should be stored in carriers or fixed in suitable trays which are intended for cleaning and to prevent movement during instrument processing. Instruments with jaw such as forceps, graspers, scissors, dissectors and needle holders must have the jaws in an open position before cleaning. Instruments equipped with a lock connection should be opened and force flushed using the appropriate equipment and pressure flushing system. Distilled water is recommended to be used as the final rinse to avoid water staining and corrosion on the instrument. Follow equipment manufacturer’s drying cycle recommendations. It is recommended that the interior sheath be further manually dried via compressed air pistol to ensure effective internal drying.

Also inspect the instruments for any damaged, worn, corroded, pitted / porous conditions and ensure proper function. Contact Geri if damage is observed and if repair is necessary. Apply non-silicone instrument lubricant to the joints and jaws of the instrument to ensure easy movement. Caution: Do not oil electrical connections on instruments.

 

Ultrasonic Cleaners:

 

Ultrasonic Cleaners can also be used for cleaning and removal of contamination and debris. Follow the Ultrasonic Cleaner manufacturer’s recommendations for cleaning agents, fill levels, temperature, processing time, etc. Make sure that functional parts do not touch other instruments and all jointed instruments are processed in an open position. We recommend pre-flushing instruments via the equipped LOCK connection which should be opened and force flushed using the appropriate equipment prior to immersion in the ultrasonic bath. After cleaning and disinfection, the instruments should be thoroughly rinsed, both on the exterior and interior sheath, with distilled water. Immediately dry instruments to prevent corrosion. Drying can be performed manually, but compressed air pistol is recommended for more delicate instruments and is more effective for overall drying.

 

Warning: Ultrasonic cleaning should never be used for endoscopes and instruments with tungsten carbide insert.

 

 

2. STERILIZATION

 

Steam sterilization should be carried out by steam under pressure in the complete absence of air in an autoclave set at 134 Celsius as follows:

 

Temperature 134 Celsius, Sterilization time = 5 min.

 

Instruments jaws and ratchets must be in open position to avoid damage during the sterilization heating and cooling process. Always follow the autoclave manufacturer instructions and recommendations. For autoclaving, place the instruments in a suitable container or sterilization tray. Cutting edges and tips of instruments should always be protected with a soft cloth.

 

After autoclaving allow all components cool down to room temperature. Sudden changes in temperature may cause damage  to the instruments.

 

 

3. GAS STERILIZATION

 

Place the pre-cleaned instrument in a transparent aseptic package. It is recommended to cover tips and cutting edges of instruments to avoid perforation of packaging. Follow the instruction manual of the manufacturer of the gas sterilization equipment and observe domestic health care regulations. Allow sufficient time for ventilation to remove toxic residues.
