Problems solved by technology

However, the above-mentioned joint support usually has the following problems: 1. High cost, complex structure, and large size; 2. When the spring shrinks, the force exerted by the spring gradually decreases
As a result, when using this joint support, the patient will feel uncomfortable due to the different torsional moments provided, and the rehabilitation effect is low; 3. The above-mentioned joint support has friction and impact at the kinematic pair, and the movement accuracy of the mechanism is low, which is not conducive to the overall processing

Abstract

The invention discloses a joint support device based on a compliant constant moment mechanism, which includes support units located on both sides of the limbs. The support unit includes upper and lower guard plates, and a compliant guide mechanism is arranged between the upper and lower guard plates. The compliant guide mechanism The flexible guide beam and the rotary table are included, the lower end of the upper guard plate is fixedly connected with the compliant guide beam, and the upper end of the lower guard plate is fixedly connected with the rotary table. The above scheme connects the upper and lower guard plates by setting a compliant guide mechanism. On the one hand, the upper and lower guard plates can be stably connected to fix the limbs at both ends of the joint; on the other hand, it can realize constant Torque output, the constant torque generated by the compliant guide mechanism can increase the range of motion and angle of the damaged joint, and help the muscle recovery function of the damaged joint; moreover, there is no friction at the kinematic pair of the upper and lower guards when they move relative to each other , High motion precision.

Description

technical field [0001] The invention relates to the technical field of medical devices, and specifically designs a joint support device based on a compliant constant moment mechanism. Background technique [0002] In the field of medical devices, joint support devices are mainly used for rehabilitation, healing and functional recovery of injured tissues. The general method of immobilizing the joint with a plaster board can provide a rigid surface for the damaged joint and prevent the joint from being dislocated due to the weight of the limb itself. However, some patients have flexion and stretch contractures of the muscles at the joints due to major injuries or undergone surgery at the knee joints, elbow joints, ankle joints, wrist joints, etc. In order to restore the function of the body joints, traditional plasterboard fixation The joint method is no longer applicable. [0003] In the prior art, a joint support that can provide a torsional moment to the body is usually u...
