Description

Technical Field

[0001] The invention relates to the technical field of medical rehabilitation training equipment, in particular to an autonomous rehabilitation training tool for shoulder joints. Background Art

[0002] The shoulder joint is extremely susceptible to the influence of many factors. When the shoulder joint is subjected to external impact, or is strained due to long-term overuse, and with the increase of age, the tendon gradually degenerates, and the rotator cuff injury is prone to occur. Scientific and effective rehabilitation training after surgery is the key prerequisite for the good recovery of shoulder joint function. In the postoperative rehabilitation process of rotator cuff injury, brace fixation plays an indispensable role. It can provide reliable support and stability for the shoulder joint, and effectively prevent the rotator cuff from being injured again during the recovery process. When performing shoulder joint functional exercises, it is often necessary to remove or partially remove the shoulder joint fixation device to create conditions for the movement of the shoulder joint. In the early stage of passive motion functional training, patients usually need the assistance of others to complete the relevant movements more smoothly. However, choosing to go to a professional rehabilitation institution for rehabilitation training has many problems such as high cost and limited number of rehabilitation institutions, which brings great inconvenience to the patient's rehabilitation training.

[0003] A Chinese patent with publication number CN112545836B proposes a wearable shoulder joint autonomous rehabilitation training mechanism, including a backboard, a slide rail vertically fixed to the backboard, a rocker slider mechanism matched with the slide rail, and an arm fixing assembly hinged to the rocker slider mechanism, wherein the rocker slider mechanism includes a slider, a connecting rod and a rocker symmetrically arranged about the slide rail axis, the rocker is a retractable structure, and the other end of the rocker is hinged to the arm fixing assembly, the upper part of the backboard extends forward, and the extended part of the backboard is rotatably connected to a connecting arm, and the lower end of the connecting arm is hinged to the arm fixing assembly, the arm fixing assembly includes a left arm fixing assembly and a right arm fixing assembly, the left arm fixing assembly and the right arm fixing assembly are respectively hinged to the corresponding connecting arm, the extended part of the backboard is connected with two rotating shafts through bearings, the upper ends of the rotating shafts are respectively fixed to a group of gears meshing with each other, and the lower ends are fixed to the connecting arm.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent cannot exercise the shoulder joints on both sides at the same time, and cannot perform continuous exercise synchronously.

[0006] Based on this, the present invention designs a shoulder joint autonomous rehabilitation training tool to solve the above problems. Summary of the invention
