Problems solved by technology

However, the device tested is a prosthetic joint, the bionic degree of the loading method is not high enough, the biomechanical parameters that can be measured are limited, and the comprehensiveness is not strong enough
In fact, so far, there is no experimental platform in China that can achieve highly bionic force loading and simultaneously detect various biomechanical properties of the knee joint in vitro

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with specific embodiments. The following implementation will help those skilled in the art to further understand the present invention, but does not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0039] like figure 1 As shown, an experimental platform for bionic force loading of the isolated knee joint and comprehensive detection of the biomechanical properties of the knee joint is mainly composed of the frame unit 1, the femoral posture adjustment unit 2, and the 3-femoral reaction force and ligament strain measurement and force loading unit, 4-knee joint flexion drive unit, 5-tibial posture driven unit, 6-tibial internal and external rotation measurement unit, 7-patella posture detecti...

Abstract

The invention provides an experimental platform for knee joint force loading and biomechanical detection. The experimental platform is mainly composed of seven parts including a frame unit, a femoralpose adjustment unit, a femoral reactivity and ligament strain measurement and force loading unit, a knee joint flexion driving unit, a tibia pose driven unit, a tibia internal and external rotationmeasurement unit, and a patella pose detection unit. The device compares the biomechanical characteristics of the in-vitro knee joint under different surgical techniques by detecting the biomechanicalcharacteristics of the knee joint after surgeries such as total knee replacement, anterior cruciate ligament reconstruction, and posterior cruciate ligament reconstruction.

Description

technical field [0001] The invention belongs to the field of biomechanical experiments of isolated knee joints, in particular to an experimental platform for comprehensive detection of bionic force loading of isolated knee joints and biomechanical properties of knee joints. Background technique [0002] The knee joint is the main joint of the lower limbs of the human body. It bears a lot of weight and has a large amount of exercise, and is the hub of lower limb activities. The structure and function of the knee joint are the most complex joints in the human body. The human knee joint is mainly composed of femur, tibia, fibula and their surrounding muscles and ligaments, and belongs to a synovial joint with a very complete structure. At present, the aging population in my country is becoming more and more serious. At the same time, urban middle-class groups are paying more attention to physical exercise. The number of young people who love marathon and long-distance running ...
