Abstract

The invention provides a knee-joint osteotomy tool and a manufacturing system and manufacturing method thereof. The manufacturing method includes: receiving three-dimensional anatomical structure dataof a patient knee joint acquired through a real-time three-dimensional scanning manner, wherein the three-dimensional anatomical structure data includes data of a patient knee joint and data of anatomical feature markers on the patient knee joint; performing processing to acquire a three-dimensional knee-joint digital model according to the three-dimensional anatomical structure data, wherein thethree-dimensional knee-joint digital model includes a digital model of the patient knee joint and a digital model of the anatomical feature markers; creating a three-dimensional tool digital model ofan osteotomy positioning member according to the three-dimensional knee-joint digital model; and creating a three-dimensional tool physical model of the osteotomy positioning member according to thethree-dimensional tool digital model. Real-time three-dimensional scanning is performed on a physical operation area of the patient knee joint to complete knee-joint digital modeling, the modeling efficiency is improved, and the accuracy of knee-joint digital modeling is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a knee joint osteotomy tool and a production system and production method thereof. Background technique [0002] The knee joint is one of the largest and most important joints in the human body, and its damage will seriously affect the patient's mobility and reduce the quality of life. With the prolongation of the average life expectancy of our country's population, the incidence of degenerative osteoarthritis of the knee joint shows a significant increasing trend in the elderly population. For severely degenerated knee joints, how to maximize the reconstruction of knee joint function is an urgent problem to be solved. Total knee arthroplasty (TKA) is the technology that can achieve this knee joint reconstruction function. [0003] Total knee arthroplasty uses artificial biomaterials to replace the damaged bone and cartilage in the joint, which better achieves the purpo...
