Knee-joint prosthesis implantation process, osteotomy module thereof and device thereof

Abstract

The invention discloses a kneed prosthesis implantation method, an osteotomy module used and a using device, the kneed prosthesis implantation method comprises the following steps of measuring the data of knee joint bone tissues, extracting the data of articular cartilage and the skeleton profile, establishing a three-dimensional model in an image processor, designing the osteotomy module, determining the size and the type of the used kneed prosthesis and determining an osteotomy module model and the implantation of the kneed prosthesis. The kneed prosthesis implantation method of the invention can reduce the trauma of a patient, lower the cost, shorten the implantation time, reduce the risk of complications of a user of the kneed prosthesis and have less error and higher precision.

Description

technical field

[0001] The present invention relates to a method for implanting a knee joint prosthesis, and also relates to an osteotomy module used in the aforementioned method for implanting a knee joint prosthesis, and also relates to a device used in the aforementioned method for implanting a knee joint prosthesis. Background technique

[0002] At present, when people's knee joints are worn or broken, more and more people choose to install artificial knee joints to replace the original knee joints. How to implant the knee prosthesis more accurately in artificial knee replacement surgery is very important for the postoperative function and prognosis of patients. At present, the implantation of knee joint prosthesis mainly relies on the following two methods: one method is to use intramedullary and extramedullary positioning instruments during operation: when using this method, intramedullary positioning is generally used on the femoral side, and the intramedullary positi...
