Abstract

The invention provides a tibial platform gasket. The tibial platform gasket comprises a shell, a stress measuring unit and a data transmission processing unit, and contact points are arranged on the shell; the stress measuring unit is arranged inside the shell and connected with the contact points to measure tension data of two preset areas of a joint soft tissue in contact with the shell; the data transmission processing unit is connected with the stress measuring unit and a terminal device, used for computing tension difference data of the two preset areas based on the tension data of the two preset areas and transmitting the tension difference data to the terminal device after the tension difference data is processed. Thus, it is possible to accurately measure the balance of the soft tissue in total knee arthroplasty, it is not necessary for a surgeon to make judgment based on experience, technique and subjectivity, and the standardization of a surgery and the final surgical effectare ensured. The problem of being unable to monitor in real time the stress condition of a prosthesis implanted into a human body after the total knee arthroplasty is solved.

Description

Technical field [0001] The present invention relates to the field of medical equipment, in particular to a tibial platform gasket. Background technique [0002] As one of the main joint replacements, total knee arthroplasty is a mature operation. The success of total knee arthroplasty and the influencing factors of clinical efficacy have always been people's concerns. To achieve good long-term clinical effects, it is important to select indications, select prostheses, accurate surgical techniques, and pre-operative management. Attention should be paid to the correction of articular varus and flexion deformities and tibial prostheses. The correct placement of the tibial prosthesis can reduce the loosening of the tibial prosthesis. At the same time, early functional exercises are carried out to reduce postoperative complications. [0003] Poor recovery after surgery can cause muscle atrophy, cause joint instability, and damage the prosthesis. Excessive exercise and incorrect joint ...
