Cable-controlled upper limb functional training robotic arm

Abstract

The invention relates to a cable control type upper limb function training robot arm. An elbow joint is connected with a shoulder joint through an elbow joint U-shaped device; the shoulder joint is connected with a main rod by a shoulder joint U-shaped device and a scapula device; an elbow joint shaft passes through and is connected with the front part of a large arm rod in the elbow joint U-shaped device and is sleeved with an elbow joint roller which is fixedly connected with the elbow joint U-shaped device; a shoulder joint roller is connected in the shoulder joint U-shaped device; a shoulder joint shaft passes through and is connected with the scapula device and fixedly connected with an elbow joint large guide wheel; shoulder joint left-upper and right-upper guide wheels and shoulderjoint left-lower and right-lower guide wheels are arranged in the scapula device respectively; the scapula device is connected with a main rod frame through an intermediate main rod shaft; the main rod shaft is fixedly connected with a main rod roller; four main rod guide wheels are arranged at the rear end of the main rod frame respectively; and two main rod guide wheels are arranged at the lower end of the main rod frame. The cable control type upper limb function training robot arm can ensure that arms are far away from a motor so as to finish the movement that the motor drives a steel wire rope and then the steel wire rope drives various joints, and can also conveniently convert the functional rehabilitation training of left and right arms.

Description

technical field [0001] The invention relates to a rehabilitation training device for upper limb dysfunction, in particular to a rehabilitation training device for upper limb dysfunction caused by stroke (including upper limb functional nerve rehabilitation); it can also be used for upper limb dysfunction caused by cerebral palsy, trauma, diabetes, etc. Rehabilitation training robotic arm. Background technique [0002] There are many stroke survivors, among which hemiplegia and loss of walking ability are the most important sequelae. About 85% of patients after stroke have upper limb dysfunction, and 55-75% of them still have upper limb dysfunction 3-6 months after the onset. Research on the recovery of upper limb function after stroke has become a clinical rehabilitation The most challenging subject in the field. [0003] At present, electric upper limb rehabilitation arms at home and abroad generally install the motor on the joint, which is not only unsightly, but also of...

AI Technical Summary

Problems solved by technology

[0003] At present, electric upper limb rehabilitation arms at home and abroad generally install the motor on the joint, which is not only unsightly, but also often brings noise to the patient. At the same time, the increase in the size of the arm caused by the motor will also bring psychological pressure to the patient. In addition, generally The electric upper limb rehabilitation arm can only perform single-arm rehabilitation training, and patients with dysfunction in both arms cannot train their arms separately, which greatly reduces the application efficiency of the product
