Rehabilitation teaching device for simulating wrist and ankle joint structures of human body

Abstract

The invention discloses a rehabilitation teaching device for simulating the wrist and ankle joint structures of a human body. The device comprises a base; the upper surface of the base is fixedly connected with a motor; the left end of an output shaft on the motor is fixedly connected with a first shaft; the surface, close to the left end, of the first shaft is fixedly sleeved with a first bevel gear; the surface of the first bevel gear is engaged with a second bevel gear; the inner wall of the second bevel gear is fixedly connected with a second shaft; the bottom of the second shaft is rotationally connected with a fixed shaft of the upper surface of the base.In an actual use process, due to the fact that a traditional rehabilitation teaching demonstration device is difficult to fully simulate the freedom degree and the movement range of the wrist and ankle joints of the human body, and meanwhile in a teaching demonstration process, the wrist and ankle joints of the human body are difficult to display in all directions and at multiple angles, and meanwhile, students in the back row in a classroom are difficult to learn teaching contents, and as a result, the teaching efficiency and quality are difficult to improve.Through the cooperative use of the structures of the device, the above problems are solved.

Description

technical field [0001] The invention relates to the technical field of medical rehabilitation equipment, in particular to a rehabilitation teaching device for simulating the structure of human wrist and ankle joints. Background technique [0002] As the field of robotics, the joints in the upper and lower limbs of the bionic human body are the focus and difficulty of research. In this field, at present, the bionics of each joint is only to realize the general motion function, the external characteristics of the structure and the intelligent bionics. In terms of motion function, it can realize the degrees of freedom and range of motion similar to the upper and lower limbs of the real human body. [0003] However, the activities of each joint in the real human body are closely related to the tendon group, and its activities are driven by the tendon group. During the driving process, different rotation angles of the wrist and ankle joints will have different effects on rehabili...

AI Technical Summary

Problems solved by technology

It is difficult for traditional rehabilitation teaching demonstration devices to fully simulate the degrees of freedom and range of motion of the human wrist and ankle joints. At the same time, it is also difficult to display the human wrist and ankle joints in all directions and from multiple angles during the teaching demonstration process. It is difficult for the students in the row to learn the teaching content, which makes it difficult to improve the teaching efficiency and quality
