Redundant parallel femur fracture reduction robot

Abstract

The invention belongs to the technical field of medical devices, and specifically relates to a redundant parallel femur fracture reduction robot, which aims to solve the problem that the surgical robot reset operation in the prior art is not accurate enough, some broken bones are difficult to reach, and iatrogenic problems may be caused during the reset operation. For the problem of injury, the redundant parallel femoral fracture reduction robot provided by this application includes a movable platform, a redundant drive base, a parallel actuator and a clamping device sequentially installed on the movable platform, wherein the redundant drive base The base can be used in different parallel structures, and according to the characteristics of the base with 9 degrees of freedom, the parallel mechanism installed on the base can realize redundant drive, increase the working space of the position and attitude of the robot, and improve the flexibility of the mechanism It avoids the singularity of the mechanism and makes it easier to control the pose. This application is versatile and can be used in different occasions to improve the common shortcomings of parallel robots.

Description

Technical field [0001] The present invention belongs to the technical field of medical devices, and specific relates to a redundant parallel femur fracture reset robot. Background technique [0002] Traditional femur fracture reset surgery in clinically mainly used method is to obtain the location of both ends of the real-time fracture, which use X-ray image techniques in the operation, and then directly reset directly according to the obtained location information, or by means of simple The traction mechanism assisted doctor performs reset operation, this method is highly relied on the doctor's clinical experience and has a high requirements for the doctor; Exposing in the process is longer in the ray, and more and more cases have been increasing in the case of femoral bone fracture in recent years, and the damage caused by doctors is getting bigger and bigger. [0003] With the development of robotics and medical imaging navigation technology, it has obtained more and more atte...
