Embodiment Construction

[0080] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0081] see figure 1 , Figure 1A , Figure 1B , Figure 7 As shown, the present invention has designed a kind of jig that cooperates with the robot arm-universal sensor testing system to realize the biomechanical test of the knee joint. The jig is composed of a tibial shaft fixation mechanism and a femoral shaft fixation mechanism. The backbone fixation mechanism is combined into one by the knee joint specimen 10 (one end of the knee joint is the tibial shaft, and the other end is the femoral shaft) (such as Figure 7 shown). The clamp of the present invention is fixed on the mechanical arm of the robot arm-universal sensor system through the upper support member 1. When the clamp of the invention is applied to the robot arm-universal sensor system, it can be used as an auxiliary tool for the system.

[0082] The tibial shaft fixation mechanism is compos...

Abstract

The invention discloses a clamp for assisting a mechanical arm-universal sensor testing system in realizing a knee joint biomechanical test. The clamp consists of a tibia shaft fixing mechanism and a femur shaft fixing mechanism; and a knee joint specimen is connected between the tibia shaft fixing mechanism and the femur shaft fixing mechanism. An upper bottom plate (2) is arranged between a supporting (1) and an upper clamping piece (3), and a knee joint tibia is fixed by the upper clamping piece (3). A lower bottom plate (12) is arranged between a lower clamping piece (11) and a lower base (13), and a knee joint femur is fixed by the lower clamping piece (11). A top block is pushed by a squeezing screw, so that the upper bottom plate (2) and the lower bottom plate (12) are pushed, an oblique movement sliding groove panel on the side of each bottom plate and an oblique movement sliding groove panel of a wedge block are superposed to form right-angle intersected inclined grooves to be occluded, the problem about the measuring position precision during repeated mounting and dismounting of the knee joint specimen is solved, and biomechanical tests of the knee joint specimen under different states are completed.

Description

technical field [0001] The invention relates to a fixture for assisting biomechanics measurement, more particularly, a fixture for assisting a robotic arm-universal sensor testing system to realize knee joint biomechanics testing. Background technique [0002] The knee joint is the largest and most complex joint in the human body, and it is also the joint with the highest incidence of ligament damage. The knee ligament is the main structure to maintain the stability and kinematics of the knee joint. The treatment of knee ligament injury has become the main content in the field of sports trauma. [0003] Measuring the stability and kinematics of the knee joint after knee ligament injury and reconstruction can objectively evaluate the surgical method. In the past, there was only an anatomical basis in the process of establishing and improving the surgical method, and anatomical reasons are enough. Anatomical research It belongs to morphological research and cannot represent f...
