Abstract

The invention relates to a knee joint dynamic simulation device. The device comprises a hip joint simulation module, a thigh simulation module and a foot fixation module; the hip joint simulation module comprises a weight simulation block, a hip joint vertical sliding pair and a hip joint rotating pair, and is used for simulating the change of the center of gravity of squatting of a human body andhip joint movement; the thigh simulation model comprises a simulated bone plate, a quadriceps femoris connecting part and hamstring muscle connecting part, fixes specimen leg thighbone and is connected with tendons pulling the quadriceps femoris and the hamstring muscle, and is used for simulating the action of the thigh muscle in the squatting process; the foot fixation module is used for fixingthe foot of the specimen leg. By means of the weight simulation block, the device can move under the action of the gravity to bend the knee joint of the specimen leg to reproduce the movement state of the knee joint of the specimen leg, and dynamic simulation of the knee joint is completed.

Description

technical field [0001] The invention relates to the technical field of biomedical instruments, in particular to a knee joint dynamic simulation device. Background technique [0002] When researching a certain technology or product in biomedicine, it is usually necessary to use cadavers for testing to verify the rationality and feasibility of the method or product. The knee joint is an important joint in the human body, and it is easily damaged with a high incidence rate. There is currently a lot of research on different surgical approaches for knee arthrosis as well as implants in the knee joint. For issues such as whether the knee surgery method is feasible, whether the implant design is reasonable, and which technology or product has more advantages, the test and verification of the specimen leg are of indispensable value. However, the prior art can only conduct static research on the cadaver, and there is no device that can realize the dynamic simulation of the knee joi...
