Abstract

The invention discloses a method and a device for adjusting a knee joint prosthesis. The method comprises the following steps of: acquiring contact data of a contact area of a condyle surface of a current knee prosthesis, wherein the contact data comprises at least a contact stress and a contact area; acquiring physiological demand data of the target object; based on the contact data and the physiological demand data, determining whether to adjust the curvature of the current knee prosthesis. The method and the device solve the technical problem that the prior art is unable to improve and adjust the knee joint prosthesis for different patients, which leads to the inability to provide the knee joint prosthesis meeting the personalized needs of users.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method and device for adjusting a knee joint prosthesis. Background technique [0002] With the gradual improvement of living standards and medical standards, people's requirements for personalized medicine are also gradually increasing. In the technical field of knee joint replacement, the performance of the existing knee joint prosthesis is aimed at restoring the patient's knee joint physiological movement performance, and mass-produced knee joint prosthesis components are mainly used. to satisfy the market's needs. [0003] However, the existing knee prosthesis only focuses on improving the physiological performance of the knee joint of patients, but does not adopt different improvement methods for different patients, and still lacks the advantages of personalized implant prosthesis, resulting in failure to provide users Knee joint prostheses that meet the individual need...
