Embodiment Construction

[0050] A robot used for bone joint replacement surgery of the present invention has the function of completing hip joint and knee joint orthopedic surgery. Depending on the complexity of the operation, it can independently perform hip, knee, and shoulder replacement orthopedic operations, and cooperate with doctors to complete total hip replacement, total knee replacement, total shoulder replacement, and unicondylar replacement.

[0051] The hardware part of the system is usually composed of three parts: robotic arm system, navigation system and main console system; the software part adopts an optimized human-computer interaction strategy based on the habits of domestic doctors, and embeds a completely self-developed intraoperative safety protection strategy algorithm. It can effectively prevent accidental injury to important tissues of the patient during the operation, thereby further ensuring the safety and accuracy of the operation. Such as figure 1 As shown, the present i...

Abstract

The invention relates to a robot for bone joint replacement surgery. According to the robot, CT three-dimensional reconstruction, conversion of a three-dimensional model and an actual coordinate system, intraoperative visual servo and a path specification method based on an artificial potential field method are fused into a bone joint surgical robot. According to the invention, a surgical robot which can be used for shoulder joint replacement, hip joint replacement, knee joint replacement or unicompartmental knee replacement is newly provided; compared with an existing bone joint surgical robot, the functions are more comprehensive, the positioning and navigation planning speed is higher, and the accuracy is higher; an augmented reality technology based on three-dimensional visualization and feature point matching is adopted to realize three-dimensional reconstruction of the CT image of the preoperative patient; a six-dimensional force sensor is installed on the wrist of the robot, the contact force measured in real time is used for collision detection and intraoperative safety detection when the mechanical arm searches for the operation position, and the safety of the robot operation is guaranteed in combination with an emergency stop measure; and the invention mainly aims to provide a bone joint replacement surgical robot with a function of completing hip joint and knee joint orthopedic surgery.

Description

technical field [0001] The invention relates to a robot, in particular to a robot used for bone joint replacement surgery. Background technique [0002] The market size potential of the medical robot industry is very large, but in the world, orthopedic robots, as a subdivision of medical robots, have long been monopolized by leading medical devices in the United States (such as Medtronic, Stryker, and Zimmer Biomet) , the only orthopedic robot company from China is Beijing Tianzhihang Medical Technology Co., Ltd., and its main product is officially "Tianji" orthopedic robot. It is the orthopedic robot that can carry out full-segment surgery in the world, but because its use is traumatic fracture surgery, it is not suitable for the bone joint replacement surgery field of the present invention. [0003] Therefore, specialized orthopedic surgery robots have become an inevitable trend in future development. Bone joint surgery robot is the earliest orthopedic robot put into res...
