Description

TECHNICAL FIELD

[0001] The utility model relates to medical rehabilitation technical field especially wrist rehabilitation mechanical arm joint protective sleeve. BACKGROUND

[0002] In the field of rehabilitation medicine, the rehabilitation training of the wrist part has been an important link for treating wrist injury and restoring wrist function. Wrist injury can be caused by various reasons such as accidents, sports injuries, and long-term strain. Effective rehabilitation training is crucial for pain relief, muscle strength enhancement, and joint flexibility recovery. In recent years, with the rapid development of robot technology, mechanical arms have been widely used in the field of medical rehabilitation, especially in wrist rehabilitation training. Mechanical arms can provide precise and controllable movement trajectories and force output, thereby helping patients achieve personalized rehabilitation training plans.

[0003] The existing wrist joint rehabilitation training devices do not have the function of selecting appropriate grips according to the shape of the patient's fingers, which cannot meet the requirements of different patients with different hand shapes, resulting in loose or falling of the patient's hand and the grip during rehabilitation training, affecting the rehabilitation effect, and even causing additional injuries.

[0004] The existing patent (publication number: CN209019343U) is a wrist joint rehabilitation training device, which includes a base, an arm support mechanism, a holding mechanism, a power transmission mechanism, a detection mechanism, and a control system. The base is provided with a left support seat and a right support seat. The power transmission mechanism is installed on the right support seat. The holding mechanism is connected to the mechanical output power shaft of the power transmission mechanism through the right connecting swing arm. The left support seat is movably connected with a left connecting swing arm symmetrically arranged with the right connecting swing arm. The left connecting swing arm is fixedly connected with the holding mechanism. The arm support mechanism includes an arm support plate, and a height adjusting device is arranged below the arm support plate. The holding assembly is composed of a holding rod and an angle adjusting device. The angle adjusting device can adjust the angle of the holding rod. The height adjusting mechanism is used to better realize the positioning of the wrist joint axis. The holding mechanism can be continuously adjusted at multiple angles, and can actively or passively train and monitor in real time. The holding mechanism can be conveniently and quickly replaced according to the differences in the patient's hand.
