Holding mechanism of wrist rehabilitation training device

Abstract

The invention discloses a holding mechanism of a wrist rehabilitation training device. The holding mechanism of the wrist rehabilitation training device comprises a bottom base. The bottom base is provided with a machine head component. The machine head component comprises a holding component and a driving component. The driving component is connected with a power shaft of mechanical output. The power shaft is connected with the holding component. The holding component is formed by a holding rod and an angle regulating device. The angle regulating device is capable of regulating the angle of the holding rod. The angle regulating device comprises a fixing ring, a limiting ring fixedly connected to one side of the fixing ring and a regulating ring rotatably installed between the fixing ringand the limiting ring. The angle regulating device further comprises a positioning device. The positioning device is capable of positioning the regulating ring and preventing the regulating ring fromrotating. The holding mechanism of the wrist rehabilitation training device is capable of assisting a convalescent to train the wrist joints in the multi-direction, enabling the functions of the wristjoints of the convalescent to be rehabilited and trained, and assisting the convalescent to recover the functions of the wrist joints better.

Description

Technical field [0001] The invention belongs to the technical field of medical equipment, and specifically relates to a gripping mechanism of a wrist joint rehabilitation training device. Background technique [0002] The existing wrist joint rehabilitation training device can only train the wrist palm or the dorsiflexion and extension of the hand. The training degree of freedom is single, and the wrist joint adduction / abduction degree of freedom cannot be trained, which affects the patient's recovery speed. For the wrist joint rehabilitation , The wrist belongs to a multi-degree-of-freedom joint, only training in a certain direction is not conducive to the comprehensive rehabilitation of the wrist joint. [0003] Moreover, there is a certain inclination angle for the grasping of the hands of patients with hemiplegia, but the grips of the existing wrist joint training devices are all set horizontally. It is not considered that the hands of some patients can no longer maintain the l...

AI Technical Summary

Problems solved by technology

[0002] Existing wrist joint rehabilitation training devices can only train the flexion and extension of the wrist, palm or back of the hand, and the training degree of freedom is single. , the wrist is a multi-degree-of-freedom movable joint, and only training in one direction is not conducive to the comprehensive rehabilitation of the wrist joint

[0003] And there is a certain inclination angle for the grasping of the hands of hemiplegic patients, but the grips of the existing wrist joint training devices are all set horizontally, which does not take into account that the hands of some patients can no longer maintain the horizontal state of normal people, and there is already a certain inclination angle. When grasping the horizontal grip, it is easy to loosen and fall off the grip, which will affect the effect of rehabilitation training and even cause damage to the wrist joint

[0004] In addition, the fingers of hemiplegic patients are often deformed, showing differential flexion and extension, so it is necessary to choose a grip suitable for the patient according to the shape of the fingers of different patients. The function of choosing a suitable grip for the finger shape cannot meet the requirements of different hand shapes of different patients, resulting in loosening and falling off of the patient's hand and grip during rehabilitation training, affecting the rehabilitation effect, and may even cause additional damage; of course , still facing a problem is how to replace the grip conveniently and quickly to reduce the workload of the medical staff, and the grip after installation should be firm and stable, which requires a quick disassembly device to facilitate and quick replacement of the grip
