Design method of guide plate for total hip replacement and related equipment

Abstract

The invention provides a design method of a guide plate for total hip replacement and related equipment. The method comprises the steps: determining a corresponding three-dimensional image based on the medical image data of a target part, and selecting an adaptive prosthesis model in a pre-stored total hip prosthesis database; generating a simulation guide plate matched with the prosthesis model, and obtaining guide plate design data; wherein the guide plate design data is used for processing and manufacturing the total hip joint prosthesis. According to the invention, design difficulty of the artificial total hip joint guide plate is reduced, the design period of the guide plate is shortened, the production efficiency of the guide plate used for the artificial total hip joint replacement surgery is remarkably improved, an operator is assisted to finish the surgery more accurately and efficiently, and the clinical effect is further improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a design method of a guide plate for total hip joint replacement and related equipment. Background technique [0002] Total hip arthroplasty is an important means of treating hip joint diseases such as femoral head necrosis and hip dysplasia. In recent years, with the advancement of surgical technology and the continuous optimization of surgical planning parameters, artificial total hip replacement has gradually been accepted by more doctors and patients. [0003] Some studies have proved that in total hip replacement surgery, the position deviation of the prosthesis will increase the impact force on the prosthesis, accelerate the osteolysis and migration around the prosthesis, change the biomechanical stability of the human body, and eventually lead to prosthetics. Therefore, the precise positioning of the prosthesis installation in artificial total hip replacement surg...
