[0002] The liftable surgical hook for hepatobiliary surgery is a medical auxiliary device designed specifically for hepatobiliary surgery. It allows the height of the surgical hook to be adjusted during surgery to adapt to the physical conditions and surgical needs of different patients. This design improves the flexibility and efficiency of the surgery while reducing the labor intensity of medical staff.

[0003] Chinese patent: Application number CN202110297691.6 discloses a liftable surgical hook for hepatobiliary surgery, including a fixing device, which has two fixing devices: universal wheels, with universal wheels symmetrically rotatably arranged on both sides of the bottom of one side of the fixing device; a push handle, with a push handle arranged on one side of the top of the fixing device on one side: a lifting mechanism, and with a lifting mechanism arranged on one side of the top of the fixing device on the other side: a hanging mechanism, with a hanging mechanism arranged on the lifting mechanism. The inventors hold the pushing handle and move the surgical hook to a suitable position through the action of the universal wheel, and the inventors can adjust the lifting mechanism, thereby adjusting the height of the hanging mechanism; Although such a setting can move the surgical hook to a suitable position through the action of the universal wheel, and people can adjust the lifting mechanism to adjust the height of the hanging mechanism, the medical instrument knife on the hook usually needs to be disinfected after use to prevent the medical instrument knife from causing infection to the patient when it is used again. Usually, the medical instrument knife needs to be used multiple times during an operation. The surgical hook of this setting does not have a corresponding structure for disinfecting the medical instrument knife. After the medical instrument knife is used, it usually needs to be manually disinfected and then hung on the hook. This process requires back and forth operations, which increases the cumbersomeness of using the medical instrument knife and will affect the use of the medical instrument knife to a certain extent. Summary of the invention

The disinfectant in the liquid storage tank 901 is extracted by the cylinder 401 through the infusion pipe 902, and the disinfectant in the liquid storage and infusion assembly 9 is sucked into the inside of the cylinder 401, and then discharged in sequence through the spray hole 404. Fig. 9 , the spray hole 404 faces the hook 10 and the medical device cutter, the disinfectant is sprayed toward the hook 10 and the medical device cutter for disinfection, and the first spring 403 is used to reset the movable rod 402 and the piston 405; When the piston 405 moves downward, the spray hole 404 sprays from top to bottom in sequence, and the pressing component 6 continues to be pressed to the bottom. The sponges 11 on the first mounting slot plate 801 and the second mounting slot plate 802 approach each other. Because the spray hole 404 faces the hook 10 and the medical device tool, the outer shell surfaces of the first mounting slot plate 801 and the second mounting slot plate 802 block the spray hole 404. The disinfectant sprayed from the spray hole 404 cannot be sprayed toward the sponge 11 at this time. The two sponges 11 approach the medical device tool, move downward and rub the medical device tool, thereby wiping off the water stains on the medical device tool for subsequent continued use.
