Rapid replacing mechanism for orthopedic surgery assisting robot end tool and rapid replacing method

Abstract

The invention discloses a rapid replacing mechanism for an orthopedic surgery assisting robot end tool and a rapid replacing method. By using a locking pin, a locking groove, a stopping part and elastic parts in a combined mode, the locking groove tightly presses the locking pin on the stopping part under the action of a spring force so as to achieve limiting, relative to the locking groove, of the locking pin in the groove depth direction; meanwhile, the locking pin is in inclined surface connection with the locking groove so as to achieve limiting, relative to the locking groove, of the locking pin in the groove length direction, by overcoming the acting force of the springs under the exogenic action, unlocking of the locking pin and the locking groove in the groove depth direction can be achieved, then unlocking in the groove length direction is conducted, and rapid dissembling and assembling of the locking pin and the locking groove are achieved. The robot end and the surgical tool can be disassembled and assembled rapidly, and therefore the adaptability and acceptability of an orthopedic surgery robot in an operating room are improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a quick-change mechanism and a quick-change method for end tools of an orthopedic surgery auxiliary robot. Background technique [0002] The orthopedic surgical robot is one of the earliest surgical robots to be researched and applied in the medical field, and it is also a surgical robot that has been studied more at home and abroad. ) clinical license. [0003] During orthopedic surgery, robotic end-of-surgery tools will need to be replaced frequently according to surgical needs. For this reason, in the design of orthopedic surgery robots, the end connections of the robots are all designed as industrially common flange structures for the replacement of surgical tools. This multi-screw-fixed joint is difficult to be accepted in the operating room because of the waste of doctor's ineffective work time. Especially considering issues such as disinfection and sterilization, the ro...

AI Technical Summary

Problems solved by technology

This kind of joint fixed by multiple screws is difficult to be accepted in the operating room because it consumes the doctor's ineffective work time

Especially considering issues such as disinfection and sterilization, the robot is wrapped with a layer of disinfection curtain during the operation, which is a critical factor in clinical acceptability for orthopedic operations where surgical tools at the end of the robot need to be replaced frequently during the operation. Big challenges will also limit the clinical promotion of orthopedic surgical robots
