Technical Field

[0001] This invention relates to the field of surgical instruments, specifically to a disassembly and assembly mechanism and method for assisted sterilization of a spinal endoscopic surgical robot. Background Technology

[0002] Traditional spinal endoscopic surgical instruments require cleaning and soaking in a high-efficiency disinfectant after surgery. Following cleaning and disinfection, the instruments are dried and then sterilized using a low-temperature sterilization method. During the procedure, sterile drapes are used to completely isolate unsterilized instruments from sterilized instruments. However, in robot-assisted spinal endoscopic surgery, it is impossible to completely isolate the unsterilized surgical robot from the sterilized endoscope, working cannula, and other instruments using sterile protective covers.
