Problems solved by technology

[0003] However, the models in the prior art can only realize the rotation of the tibia and femur within a certain angle, but cannot realize the rotation and swing of the tibia and femur, and cannot highly restore the movement mode of the knee joint limbs of the real human body, resulting in the force line of the knee joint and The accuracy of determining the center position of the femoral head is not high, which seriously restricts the development of surgical robots

Abstract

The invention provides a human body lower limb movement simulation device which comprises a pelvis model, a thighbone model and a tibia model and further comprises a base, a first seat, a first fixing part, a linkage assembly, a second seat and a second fixing part. The base is provided with a flat surface, a guide rail is arranged on the flat surface, and the pelvis model is arranged on the base and is the same as the supine position of a human body; the first seat and the guide rail form a moving pair; the first fixing part is used for fixing and supporting the thighbone model; the linkage component forms a spherical pair with the first seat and the first fixing part respectively; the second seat and the guide rail form a moving pair; the second fixing part is used for fixing and supporting the tibia model and forms a spherical pair with the second seat. The limb movement mode of a real human knee joint is highly restored, the knee joint force line and the thighbone center position can be accurately determined when a knee joint surgery robot is matched for simulation operation, and powerful support is provided for clinical application of knee joint surgery and development of related products.

Description

technical field [0001] The present invention generally relates to the technical field of human lower limb models, and in particular, relates to a human lower limb motion simulation device. Background technique [0002] Because the knee joint is the largest and most complex joint in the human body, it has a greater chance of injury. With the continuous development of AI technology, smart medical care is also constantly introducing new ones. Knee surgery robots have been applied to clinical and telemedicine. In the process of developing a surgical robot, it is necessary to simulate the surgical steps and human body position, so a model that can simulate the movement of the knee joint limbs is needed to cooperate with the simulation operation of the knee joint surgical robot. [0003] However, the models in the prior art can only realize the rotation of the tibia and femur within a certain angle, but cannot realize the rotation and swing of the tibia and femur, and cannot high...
