Surgical instrument maintenance methods and precautions Surgical instrument maintenance methods and precautions are worth studying. Maintenance of surgical instruments can affect the service life of surgical instruments. Maintenance of surgical instruments is generally after maintenance, cleaning and disinfection. Before the maintenance of surgical instruments, please pay attention to the precautions of surgical instruments: clean the surgical instruments immediately after surgery, mainly to clean the blood spots on the surgical instruments, you can use soft linen, plastic brushes or cleaning guns, etc., surgical instruments can not use metal brushes or Rinse the reagents to avoid damage to the instrument. 1. High temperature and high pressure steam physical method should be preferred for sterilization Any chemical sterilization and sterilization will have different degrees of influence on the device. Therefore, the unit with conditions should prefer the high temperature and high pressure physical method to disinfect and sterilize, which can effectively extend the service life of the device. Chemical disinfection may be used if conditions are not available, but must be handled in strict accordance with the appropriate specifications. 2. Special attention should be paid when using chemical sterilization The device cannot be immersed in physiological saline because exposure to physiological saline can cause pitting and rust. When immersed and disinfected with a disinfectant such as glutaraldehyde, available chlorine or effective bromine, it must be operated strictly according to the concentration and soaking time specified in the instruction manual, and a 0.5% sodium nitrite metal corrosion inhibitor is added to the prepared solution. It can slow down the corrosion of the disinfectant to the instrument. Fresh disinfectant must be replaced every day to prevent corrosion due to the accumulation of contaminants and the increase in concentration caused by evaporation. When disinfecting non-stainless steel equipment, first check whether the disinfectant used is in harmony with the material to avoid damage to the equipment. 3. The instrument must be disinfected and cleaned after use. If the dirt residue remains on the device, it will make subsequent cleaning more difficult. Adhesive materials (such as filler materials) for dental instruments can damage the device if they are hardened on the device. 4. Prevent collision impact during disinfection and cleaning Collision impact can damage the chrome layer or passivation film on the surface of the device, reducing the corrosion resistance of the device. Collision impacts can cause damage to delicate instruments and edged instruments. Microsurgical instruments should have special protective measures, such as storage on a shelf or in a suitable device. Be careful not to use excessive force or pressure during the cleaning process to prevent damage to the instrument. For cutting-edge instruments such as scissors, osteotome, drill bits, curettes, etc. should be stored in a special container or placed in a suitable device to avoid damage to the cutting edge. 5. Cleaning process precautions Manual cleaning should use soft linen, plastic brush or cleaning gun, compressed air gun, etc., can not use metal brushes or rinse reagents to avoid damage to the equipment. Rubber and plastic materials in particular require special care to rinse. In order to avoid water stains, the instrument must be dried immediately after cleaning. The spliced ​​instruments (such as scissors and pliers) should be opened before disinfection and cleaning, so that the instruments can be more effectively and thoroughly disinfected. For some instruments that have internal cavity or groove structure that are difficult to clean, such as slits (kiss), endoscopes, etc., the instruments should be disassembled according to the instructions in the product manual before disinfection and cleaning. 6. Sterilization and purification product considerations The purified packaged product does not need to be cleaned in the case of intact packaging and is not contaminated. It can be used after high temperature and high pressure steam sterilization according to the conventional method. Sterilized packaging products can be used directly, but the inner packaging must be removed in the operating room. If the package is found to be damaged, it needs to be re-cleaned and sterilized. If it has exceeded the expiration date of sterilization, it should not be used. If it is to be used, it can be treated in the same way as the sterilization requirements of the product.

Electric appliances can be wiped with a soft linen cloth that cleans the disinfectant solution, or a soft brush can be used. After using spray sterilization, be sure to dry with cloth.
If the electric device is sterilized by ethylene oxide, the device should be kept dry and there should be no water droplets or stickers on the surface to avoid affecting the sterilization effect.
If the device is left untreated for a long time, contaminants can corrode the device.
When cleaning the instrument with a complete set of equipment, the instrument should be pre-opened and suspended so that the cross-sprayed water column can be flushed to each part of the instrument. If cleaning with a shallow disc containing a hole, it should be noted that the instruments in the tray should be stacked to prevent the cleaning effect from being affected by excessive stacking.
