Guidance system for hip replacement and method of use thereof

Abstract

The invention discloses a guide system for hip replacement and a using method thereof. The guide system comprises a handle, a guide connecting rod, an acetabular cup connector and a sleeve. The lower end of the handle is connected with the acetabular cup connector. One end of the guide connecting rod is connected with the side close to the upper end of the handle, a sleeve hole is formed in the other end of the guide connecting rod, and the sleeve is nested into the sleeve hole. The acetabular cup connector comprises a mounting shaft which can be connected with an acetabular cup in a rotating mode, and the center axis of the sleeve is roughly overlapped with the axis of the mounting shaft. According to the guide system for hip replacement and the using method thereof, the guide system is easy to assemble and disassemble and convenient, quick and accurate to use, the completion time of minimally invasive surgery is greatly shortened, any muscle and any joint capsule do not need to be cut off in the operation process, an acetabular component can be accurately positioned, inserted and pressed in a matched mode, and dislocation can be avoided.

Description

technical field [0001] The invention relates to a surgical tool for minimally invasive hip joint replacement and its use method, in particular to a guide system for hip joint replacement and its use method. Background technique [0002] With the transformation of the new medical model to the biological-psychological-social medical model and the formation of the concept of holistic treatment of surgical diseases, the development of minimally invasive surgery has been promoted. Minimally invasive total hip replacement is a new technique that has only appeared in recent years. It is a new surgical method, which is based on the traditional total hip arthroplasty by improving the surgical approach, operation method and surgical tools, and completes the arthroplasty in a relatively small incision (5-10cm). Body replacement requires rich experience of doctors and improvement of surgical instruments to achieve good surgical results. Therefore, higher requirements are put forward fo...

AI Technical Summary

Problems solved by technology

Therefore, minimally invasive total hip replacement surgery puts forward higher requirements for special and improved surgical tools, which can fully expose the acetabulum, prevent posterior dislocation, do not cut off muscles, retain a complete shutdown capsule, and accurately position, etc. Requirements, the current micro-trauma tools involved in the relevant patents have disadvantages such as complex use methods, difficult disassembly, or taking up a large space, and the existing tools cannot meet all requirements
