[0002] Shoulder surgery is a surgical procedure performed for shoulder injuries, degenerative diseases, infections or other pathological problems. In the first few weeks after surgery, the doctor will arrange physical therapy based on the patient's recovery to help restore the range of motion of the joint. The goal of physical therapy is to gradually restore shoulder flexibility and avoid long-term stiffness.

[0003] A commonly used post-operative shoulder exerciser is to fix the hand of the injured shoulder with a sling, and use a support point to move the hand downward and stretch the injured shoulder joint, thereby achieving therapeutic exercise for the shoulder joint. However, due to the patient's injury, the patient's strength to stretch the injured shoulder joint is insufficient, and due to the lack of sufficient strength support, the patient cannot fully perform normal stretching or movement of the shoulder joint, affecting the flexibility and functional recovery of the joint. In response to the above problems, the inventor proposes a sports medicine post-operative shoulder exerciser to solve the above problems. Summary of the Invention

[0004] In order to solve the problem that patients have insufficient strength to stretch their injured shoulder joints due to injuries, and due to lack of sufficient strength support, patients are unable to fully stretch or move their shoulder joints normally, which affects the flexibility and functional recovery of the joints; the purpose of the present invention is to provide a sports medicine exerciser for shoulder joint surgery. By setting up a rotating stretching component, the shoulder joint holding the No. 6 switch can be moved by rotating the No. 1 toggle lever, and the differential gear design of the No. 1 gear and the No. 2 gear can make it possible to stretch the shoulder joint with less force. By designing the sliding and coordinated movement of the No. 1 fixed rod and the No. 2 sliding rod, the arm rotation position can be flexibly adjusted to adapt to patients with different heights and arm lengths.

This circular rotation of the shoulder can effectively increase the range of motion of the shoulder joint and help restore joint flexibility after surgery. In the early stages of postoperative rehabilitation, the shoulder joint may be restricted in motion due to surgery or trauma. Circular rotation helps gradually restore the natural range of motion of the shoulder, avoiding stiffness and movement disorders. Circular rotation of the shoulder can also promote blood circulation in the shoulder and surrounding muscles, ligaments, and joints, helping to provide more oxygen and nutrients, thereby promoting tissue repair and recovery. Good blood circulation is crucial for postoperative recovery and helps speed up the recovery process.

[0045] The No. 1 fixed rod 301 is slidably connected to the No. 2 sliding rod 308 on the outside, and a sliding groove 309 is provided on the outside of the No. 2 sliding rod 308.

[0046] By adopting the above technical solution, the No. 2 fixing block 307 and the No. 1 fixing rod 301 can be fitted together, so that the No. 2 fixing block 307 and the No. 1 fixing rod 301 can be squeezed and fixed, and when the patients can adjust the rotation position of the arm according to their needs, they will feel more control and autonomy during the rehabilitation process, which can improve the patients' enthusiasm and participation. Active participation in rehabilitation training usually brings better recovery effects. Patients will be more willing to practice and can more clearly feel the progress brought about by the training.

[0047] The second sliding rod 308 is externally rotatably connected to the second rotating rod 303, and the second rotating rod 303 is externally fixedly installed with the second threaded rod 304. The second threaded rod 304 is threadedly connected to the third sliding block 306, and the end of the second rotating rod 303 away from the second threaded rod 304 is fixedly installed with the sixth switch 305.

[0048] By adopting the above technical solution, the No. 6 switch 305 is fixedly installed on the end of the No. 2 rotating rod 303 away from the No. 2 threaded rod 304, and the No. 3 sliding block 306 can be driven to move toward the No. 1 fixed rod 301 by rotating the No. 6 switch 305. By adjusting the position of the arm rotation, it can help ensure that they maintain the correct posture during training, which is very important to avoid additional injuries caused by improper posture. The flexible adjustment design can help patients maintain a proper posture under different training intensities and angles, thereby reducing the risk of muscle strain or joint sprain.

[0049] Working Principle: When a sports medicine exerciser for shoulder joint surgery is needed, the exerciser needs to be adjusted according to the patient's arm length. Turning the rotary switch 111 can drive the fifth shaft 112 to rotate, and the rotation of the fifth shaft 112 drives the third gear 113 to rotate. The rotation of the third gear 113 then drives the fourth gear 114 to rotate, and the rotation of the fourth gear 114 drives the sixth shaft 115 to rotate. Finally, the rotation of the sixth shaft 115 drives the first threaded rod 205 to rotate, and the rotation of the first threaded rod 205 drives the second sliding block 204 to move. The movement of the second sliding block 204 can control the height of the main turntable 3 to adapt to the patient's height.

[0050] Furthermore, the distance between the No. 1 fixing rod 301 and the No. 2 sliding rod 308 is adjusted by toggling the No. 2 sliding rod 308, and the No. 2 threaded rod 304 is rotated by rotating the No. 2 rotating rod 303, and the No. 2 threaded rod 304 is rotated, and the No. 3 sliding block 306 is driven to move by the rotation of the No. 2 threaded rod 304, and the No. 2 fixing block 307 is driven to move by the movement of the No. 3 sliding block 306, so that the No. 2 fixing block 307 can squeeze the No. 1 fixing rod 301, and finally the adjusted No. 2 sliding rod 308 is fixed to the No. 1 fixing rod 301, so that the length adjustment of the exerciser after shoulder joint surgery can be completed, and the arm rotation position can be flexibly adjusted to accommodate patients with different heights and arm lengths. The flexible adjustment of the arm rotation position can be adjusted according to the specific body shape of the patient, ensuring that the device can be suitable for different individuals, making it more comfortable and effective during use. Through personalized adjustment, the correct posture and movement during stretching or exercise can be guaranteed, avoiding improper operation or additional injuries due to inappropriate device settings;

[0051] Furthermore, the hand at one end of the injured shoulder holds the placement handle 315, and the other hand rotates the first toggle lever 101. The rotation of the first toggle lever 101 drives the second rotating shaft 102 to rotate, and the rotation of the second rotating shaft 102 drives the first right-angle gear 103 to rotate, and the rotation of the first right-angle gear 103 drives the second right-angle gear 104 to rotate. Further, the rotation of the first right-angle gear 103 drives the second right-angle gear 104 to rotate, and the rotation of the second right-angle gear 104 drives the fourth rotating shaft The shaft 105 rotates, and the rotation of the fourth shaft 105 drives the third right-angle gear 106 to rotate, and the rotation of the third right-angle gear 106 drives the fourth right-angle gear 108 to rotate, so that the circular rotation of the shoulder can not only move the joint, but also enhance the shoulder muscle strength by promoting the coordinated movement of the shoulder muscles. Postoperative rehabilitation requires gradually strengthening muscle strength to restore the stability of the shoulder joint and reduce the risk of re-injury. Through conscious shoulder rotation, the stability and support capacity of the shoulder can be enhanced.

[0052] Furthermore, the rotation of the No. 4 right-angle gear 108 can drive the No. 3 rotating shaft 107 to rotate, and the rotation of the No. 3 rotating shaft 107 can drive the No. 1 gear 109 to rotate, and finally the rotation of the No. 1 gear 109 can drive the No. 2 gear 110 to rotate, and the rotation of the No. 2 gear 110 can drive the main body turntable 3 to rotate. The rotation of the main body turntable 3 can simultaneously drive the No. 6 switch 305 to rotate and drive the patient's shoulder joint to move. The differential gear design of the No. 1 gear 109 and the No. 2 gear 110 can make the patient stretch the shoulder joint with less force. In this way, the patient does not need to directly use a large force to stretch, which helps to avoid secondary damage caused by excessive force, and can enable the shoulder joint to maintain a certain degree of flexibility and avoid joint stiffness caused by long-term inactivity.

[0053] Furthermore, when the patient rotates the No. 1 toggle rod 101 to make the placement handle 315 drive the shoulder joint to move to the maximum range and needs to be relaxed, the sliding button 313 is pressed to drive the No. 4 connecting rod 314 to move, and the No. 5 connecting rod 317 is driven to move toward the No. 2 spring 316 through the No. 4 connecting rod 314. Further, the No. 6 connecting rod 318 is driven by the movement of the No. 5 connecting rod 317 to squeeze the squeezing disc 310, and the squeezing disc 310 squeezes the No. 1 gear 109, thereby disengaging the No. 1 gear 109 from the No. 2 gear 110. At this time, the placement handle 315 can be rotated freely as the patient's shoulder joint relaxes.

[0054] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
