(1) Instruments should be handled with care, without rubbing, colliding with each other, or holding multiple instruments in one hand at the same time, keeping the flexible tips of the shaft joints closed well, and sharp instrument edges.
(2) Pay attention to the protection of the mirror surface.
(3) When the wires are cleaned and stored, they should not be disassembled and folded, and the spiral bend should be greater than 90 degrees to prevent fiber breakage, affect the use effect and shorten the service life.
(4) For all kinds of pliers, check frequently, move the joints, pay attention to the closure of the pliers ends, and apply special lubricant to the joints.
(5) Sharp instruments should be kept in rubber protective sheaths.
(6) If the sealing rings on the poke card, converter, and rotary cutter are aging or cracked, they should be replaced in time to avoid air leakage during the operation and affect the pneumoperitoneum effect.
(7) The valve on the flusher should be disassembled regularly for cleaning and oiling to maintain the flexibility of the valve.
(8) During the use, cleaning and maintenance of all instruments, the joints should not be forced, the tip should not touch hard objects, and small parts of the instruments should not be lost.

(10) It is not advisable to restart the endoscopic system within 15 minutes after shutdown.
(11) The sterilization of endoscopes is given priority to low-temperature or plasma disinfection. If high-pressure sterilization is used, the mirror must be allowed to cool naturally, and cooling with cold water is prohibited, otherwise it will cause the lens to break. At present, pentadiol is not recommended. Aldehyde immersion sterilization, because the liquid at the mirror surface interface is not easy to wipe off after soaking, misty steam will be generated during use to affect the clarity of the mirror surface, try not to change the sterilization method of the mirror frequently, which is good for the sealing of the mirror.
(12) Mirrors and surgical instruments should be cleaned separately. Wipe the mirror surface with a wet absorbent cotton ball in one direction, and then dry it with a lens tissue. Clean the mirror, otherwise it is prone to rust.
