Robot-assisted joint replacement surgical system secured to bone and method of use

Abstract

The invention provides a robot-assisted joint replacement surgical system secured to a bone and a method of use. The system comprises an electric drill, a reaming drill shaft, an operation robot, a fixing structure, an acetabulum file and a controller. The output end of the electric drill is in driving connection with the acetabulum file through the reaming shaft; the first end of the operation robot is connected to the part, close to the electric drill, of the reaming shaft, and the part, close to the acetabulum file, of the reaming shaft is a free end and can move in a limiting through hole in the second end of the operation robot. The fixing structure is connected to the operation robot, and the controller is electrically connected with the electric drill and the operation robot. The robot is fixed on the skeleton and can move along with the patient, so that the precision is very high, and the patient does not need to be fixed or a dynamic reference does not need to be connected. Compared with a traditional floor type surgical robot or a conventional surgical robot fixed to an operating bed, the adopted operation robot structure only needs a very small operating room space.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a robot-assisted joint replacement surgery system fixed on a bone and a method for using it. Background technique [0002] Joint replacement refers to a prosthesis similar to human bone joints made of metal materials, polymer materials or ceramic materials with good biocompatibility and mechanical properties. The purpose of the articular surface is to remove the lesion, remove the pain, and restore the activity and original function of the joint. Artificial joint replacement has the advantages of better joint movement, early ground activities, and reduced complications of long-term bed rest in elderly patients. The traditional method is that doctors use manual tools to perform replacement surgery, which requires high clinical experience for doctors, and the differences between individual patients make the surgery more difficult. [0003] Surgical robot-assisted surgery is curre...

Problems solved by technology

Patent document CN101947126A discloses an orthopedic surgery auxiliary robot system. Although such a robot can perform a variety of different operations, the technology is complex and it is often difficult for inexperienced surgeons to distinguish these technical errors.

At the same time, this kind of robot requires a large working space (a mechanical arm with a certain extension range or a large working space is required to adapt to operations on different parts such as knees, hips, shoulders, and spine), high cost, and a large footprint. The accuracy is not high due to robot configuration problems, which increases potential error factors and makes it difficult to present consistent surgical results
