Three-degree-of-freedom mechanical arm for lower limb rehabilitation training device

Abstract

The invention provides a three-degree-of-freedom mechanical arm for a lower limb rehabilitation training device, which comprises a fixed base arranged on a base supporting mechanism; an advancing mechanism fixedly connected to the fixed base and comprising a first linear motion module fixedly arranged on the fixed base; a lifting mechanism fixedly connected to the welding rectangular steel frame, wherein the welding rectangular steel frame is connected with the first linear motion module through a mounting base, and the lifting mechanism comprises a second linear motion module arranged on the welding rectangular steel frame; a rotating mechanism fixedly connected to the second linear motion module through an L-shaped adapter plate; and a guide rail supporting mechanism comprising a guide rail and a guide rail supporting block, wherein the guide rail is installed on the guide rail supporting block, and the guide rail supporting block is fixed to the top end of the first right-angle speed reducer of the lifting mechanism. The product can help a patient to perform lower limb exercise rehabilitation training, and can help to solve major clinical problems such as reactivation of a brain motor cortex and functional reconstruction of a motor sense network recovered after a nerve displacement operation clinically.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a three-free mechanical arm used for a lower limb rehabilitation training device. Background technique [0002] In recent years, most stroke patients suffer from different degrees of motor dysfunction after surgery. Studies have shown that more than 80% of brain injury patients have significantly improved motor function after active and effective rehabilitation training. Therefore, rehabilitation treatment is the key to the recovery of lower limb function after peripheral nerve injury repair. Personalized and targeted rehabilitation treatment can effectively promote patients' control of limbs. [0003] In the prior art, the currently commonly used lower limb rehabilitation training method is to use walking aids. However, this kind of structural routine training is generally aimed at patients with relatively mild lower limb impairment. It is not easy for sever...

Problems solved by technology

However, this kind of structural routine training is generally aimed at patients with relatively mild lower limb impairment. It is not easy for severe patients to use this method to independently train, which requires a mechanical arm to drive the lower limbs to move
