Precautions for use of ENT surgery instruments

Because ENT endoscopes are highly precise instruments, many parts have special materials, complicated structures, high cost, frequent use turnover, difficult cleaning and sterilization after use. Therefore, how to remove the organic, inorganic and microorganism contaminated on the device to a safe level through effective methods has an important role in the success of sterilization and the control and prevention of hospital infection. Proper cleaning, disinfection, and maintenance will protect the surgical instruments, extend their service life, and save costs for departments and hospitals ^[2] .

Cleaning

1) Pre-cleaning

After the special instruments were cleaned by hand, the obvious contamination was rinsed with running water, and each instrument was thoroughly rinsed. Sharp surgical instruments are separated from fine surgical instruments. Surgical instruments with different metal components should be avoided at the same time.

2) High pressure water gun cleaning

Generally, surgical instruments use a soft nylon brush of appropriate size to scrub the instruments and components. Special surgical instruments must be specially treated to avoid damaging the tip. Care should be taken during the cleaning process. Excessive pressure should not be applied to the connection. Incorrect use will cause misalignment or cracks in the gills and head.

Thoroughly brush the holes of the surgical instrument power system and the suction tube of the light guide hose with a cleaning brush. When cleaning, you must see the brush heads at both ends and clean the dirt on the brush heads.

The nose cutting drill handle must be thoroughly cleaned and maintained within 1 hour after the operation, otherwise the performance and use of the handle will be affected. Step 1: After the operation, place the handle under running fresh water for more than 30s. During the flushing, close the suction tube with your fingers several times. Step 2: Use a brush to clean the inside until no blood stains or water can be seen. Rinse the knife head, suction tube, flushing tube and other parts with a special blood stain cleaning agent for about 2s, and then spray the lubricating oil into the knife head, suction tube, and flushing tube with special lubricant for about 1s. Lubricate each joint. Finally, check whether the cutter head ring can move freely and whether the rotation movement on both sides of the crown is free.

The ear drill power system handle should also be thoroughly cleaned immediately after operation, otherwise it will affect the performance and use of the handle. The first step: turn the handle counterclockwise to decorate the jacket so that the handle is in the open state; the second step: use a special blood-stained cleaning oil bottle nozzle to align the handle with the fuel injection for 2s, and then spray the special lubricant. Remember not to rinse with a high-pressure water gun, otherwise the life of the motor inside the handle will be reduced. The inspection method is: insert the drill bit, rotate the decorative jacket clockwise, and lock the drill bit. At this time, it is normal for the drill bit to rotate flexibly. If the drill bit has resistance and is not flexible, the handle will malfunction, and the manufacturer should be contacted in time. After otology, drills and other instruments should be rinsed with water and shaken in a shaking pot for 1min. After shaking the bone fragments attached to the drill, they should be cleaned with a brush.

Dry

The problem of drying is an important issue for instrument maintenance, whether it is the nose cutting drill handle or the ear drill power system handle, this problem exists. All instruments should be thoroughly dried before disinfection to remove residual moisture. Use a soft and absorbent towel or cloth to dry the external surface. After cleaning the lumen of the cutting drill handle, there will still be water remaining inside the lumen. If it is not dried in time before sterilization, the residual water will easily enter the motor from the internal gap, which will cause rust and prevent the motor from working properly.

3. Sterilization

Common methods include ionic low-temperature sterilization, ethylene oxide sterilization, and high-temperature and high-pressure steam sterilization. Ionic low-temperature sterilization is suitable for items that are not resistant to high temperature, high pressure, and difficult to be immersed, such as endoscopic instruments, power leads, electric knife, Electrocoagulation and wire, electromagnetic, electric drill, electric saw, all kinds of rubber, plastic, silicone. For some metal and glass items that are not resistant to high temperature and high pressure, the sterilization time is about 50min; the entire sterilization time of the latter two is long, at least 24h.

maintenance

In addition to cleaning, drying and sterilizing the instrument, its care and maintenance are also steps that cannot be ignored. Because the usual cleaning can only reach the inside of the lumen, but can not reach the heart of the special instrument handle-motor, it is recommended to contact the manufacturer every 1 to 2 months for maintenance to ensure that the interior of the motor is clean and free of rust. ^[2] .
