Abstract

The invention relates to the technical field of medical auxiliary instruments, in particular to an adjustable knee joint replacement gasket test body which comprises a test body base which is hollow inside to form an accommodating space; a test body upper shell buckled on the test body base; a first jacking mechanism arranged in the accommodating space and abutting against the test body upper shell; a second jacking mechanism arranged in the accommodating space and abutting against the test body upper shell; and a transmission mechanism in transmission connection with the first jacking mechanism and the second jacking mechanism and used for driving the first jacking mechanism and the second jacking mechanism to move relative to the test body base so as to adjust the distance between the test body upper shell and the test body base. According to the adjustable knee joint replacement gasket test body, the thickness is adjusted through the rotary knob, the optimal gasket model needed by knee joint replacement can be obtained through one-time installation, repeated replacement of the gasket test body in the operation is avoided, the operation steps are simplified, and the operation time is shortened; various models of gasket test bodies do not need to be disinfected for later use, and the disinfection and supply cost is reduced.

Description

technical field [0001] The present application relates to the technical field of medical auxiliary devices, in particular to an adjustable knee joint replacement spacer test body. Background technique [0002] Total knee arthroplasty is an effective measure to treat diseases such as severe osteoarthritis; in total knee arthroplasty, choosing an appropriate type (ie thickness) of highly cross-linked polyethylene spacers is important for the balance of knee joint flexion and extension gap, joint Appropriate line height and good joint range of motion are of great significance, and they are important influencing factors of postoperative knee flexion and extension function, pain condition, and patient satisfaction. However, at present, the process of performing gasket type testing by repeatedly replacing different types of gasket specimens is time-consuming and laborious, and various types of gasket specimens need to be sterilized for backup, and the cost of disinfection and supp...
