Knee-joint function recovery trainer of below-knee amputation

Abstract

The invention discloses a knee-joint function recovery trainer of below-knee amputation, which belongs to the technical field of recovery medical instruments. The one-way output of a motor is converted into an alternate motion through a four-rod adjustment mechanism, and the angle of the alternate motion can be adjusted. Active and passive trainings can be realized by simultaneously and coaxially acting output power and the output damping of a magnetic powder torquer on the same mechanism, and output resistance and a moment can be adjusted. The trainer realizes the combination of the active and passive trainings and is suitable for patients in different recovery stages. An output limit pivot angle can be adjusted, thus the trainer can adapt to different limit knee bending angles of different patients. A motion output end is positioned in the inner sides of the legs of a patient and carries out coaxial two-way output so as to adapt to patients with amputation on different sides, thereby greatly simplifying a mechanical structure and effectively reducing the production cost.

Description

technical field [0001] The invention belongs to the technical field of rehabilitation medical devices, in particular to a knee joint function rehabilitation training device for below-knee amputee. Background technique [0002] According to modern rehabilitation theory, amputation rehabilitation is a complex systematic project. Correct lower limb amputation rehabilitation should include pre-amputation evaluation and training, amputation and postoperative treatment, evaluation and rehabilitation training, temporary and permanent prosthetic wear and use. , the whole process of psychological rehabilitation and the patient's return to family and life. [0003] In December 1995, the China Disabled Persons' Federation re-announced the total number of disabled persons and the number of various types of disabled persons nationwide based on calculations based on the results of the 1987 sample survey, and with reference to some individual statistics conducted in recent years and census...

AI Technical Summary

Problems solved by technology

[0004] Most of the rehabilitation training equipment on the market today is designed for healthy people or patients with hemiplegia. The basic and general functions are considered, and the structural design is simple. The difference between different lower limb amputee is not fully considered, and the range of motion and intensity are limited. , can not achieve a good training effect

In the prosthetic assembly centers in my country, the training equipment for the rehabilitation of residual limbs also has the same problem, and the needs of patients for rapid recovery cannot be met.
