Abstract

The invention provides prosthetic knee joint testing equipment which is used for a swinging test on a knee joint of an above-knee prosthesis. The prosthetic knee joint testing equipment is characterized in including: a bracket body which comprises four hack levers arranged vertically and a rectangular frame arranged on the top ends of the four hack levers; a prosthetic leg swinging device which comprises a prosthetic leg assembly for simulating a normal human leg and a prosthetic leg driving assembly for driving the prosthetic leg assembly to swing; a knee joint swinging device which is used for mounting the above-knee prosthesis and driving the knee joint on the above-knee prosthesis to swing, including a first thigh swinging lever mounted on a rectangular frame and fixed with a thigh piece of the above-knee prosthesis, a knee joint driving assembly and a knee joint fixing piece arranged on the bottom of the first thigh swinging lever; and ground equipment which is used to simulate relative movement of the ground, wherein the prosthetic leg assembly includes a second thigh swinging lever mounted on the rectangular frame, a lower leg swinging lever mounted on the second thigh swinging lever, and a prosthetic foot arranged on the bottom of the lower leg swinging lever.

Description

technical field [0001] The invention relates to a testing device, in particular to a prosthetic knee joint testing device. Background technique [0002] Prosthetic legs are special devices used by lower limb amputee patients to support body weight, compensate for motor function, resume daily life and work, and the knee joint is the key to lower limb prosthetics. Although the structure of the knee joint is very complex, it has high flexibility and can cooperate with other organs to complete a variety of actions. [0003] Amputee not only suffers huge physical pain and psychological trauma, but also creates a burden on family and society from an economic point of view. The current medical level is still unable to regenerate residual limbs, so the recovery of motor function of amputee patients can only be based on the installation of artificial limbs, that is, by wearing lower limb prostheses to replace the functions of healthy limbs, to complete some basic activities in daily...
