Abstract

The present invention relates to the field of medical devices, in particular to an intelligent knee joint tibial plateau test pad module, comprising a tibial plateau test pad body provided with an accommodation cavity and a force-measuring chip disposed in the accommodation cavity. The interior accommodation cavity of the present invention There is a force-measuring chip inside. When the knee joint is undergoing activity tests, the pressure sensor probes evenly arranged on the force-measuring plate frame can accurately measure and display the force distribution of the inner and outer platforms of the knee joint during the activity process. Eliminate the cause in time, achieve a balanced distribution of force, and ensure the effective cooperation of the artificial prosthesis of each component.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an intelligent knee joint tibial platform test pad module. Background technique [0002] The knee joint is the largest joint in the human body. Many experts and scholars at home and abroad have conducted research on the activities of the knee joint in normal gait and found that the knee joint movement is very complicated, not a simple flexion and extension movement. The knee joint includes flexion, extension, and rotation along the long axis of the limb. Various movements of the knee joint are realized by linkage of the femoral condyle, meniscus, proximal tibial platform, and patella. Total knee replacement surgery is a permanent replacement of the above components with an artificial prosthesis. Therefore, whether the artificial prosthesis of each component can realize its original physiological and anatomical functions is the key to determining the recovery of motion ability after...
