Description

Technical Field

[0001] This utility model belongs to the field of shoulder joint training technology, specifically relating to a shoulder joint rehabilitation training device for orthopedic surgery. Background Technology

[0002] The shoulder joint is the ball-and-socket joint with the largest range of motion in the human body. It consists of the glenoid cavity of the scapula and the head of the humerus. The shoulder joint allows the arm to move in multiple directions, including flexion, extension, internal rotation, external rotation, adduction, and abduction. When performing activities such as throwing and weightlifting, the shoulder joint can effectively transmit force, enabling the arm to generate a large torque.

[0003] Traditional shoulder joint training devices typically involve patients performing large-amplitude rotation and swinging movements of the shoulder joint. For some patients with poor recovery, performing such movements directly not only fails to provide training but may also cause secondary damage to the shoulder joint, affecting the recovery effect.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a shoulder joint rehabilitation training device for orthopedic surgery.

[0005] The information disclosed above in this background section is only intended to enhance the understanding of the background section of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0026] Example 1:

[0027] Please see Figures 1-4 As shown, a shoulder joint rehabilitation training device for orthopedic surgery includes:

[0028] The installation mechanism includes a base 2 and a vertical plate 1 fixedly installed on the upper surface of the base 2. The vertical plate 1 and the base 2 are L-shaped. One end of the vertical plate 1 has an inner cavity 19. A lifting platform 3 is provided inside the inner cavity 19. The lifting platform 3 slides with the vertical plate 1 through the inner cavity 19.

[0029] The training mechanism includes mounting arms 4 fixedly installed on both sides of the lifting platform 3. One end of the mounting arm 4 is provided with a movable shaft 12, and a movable arm 5 is installed on the movable shaft 12. The movable arm 5 is rotatably engaged with the mounting arm 4 through the movable shaft 12. A traction component is provided on the mounting arm 4. One end of the movable arm 5 is provided with a telescopic groove 13, and a telescopic arm 14 is provided in the telescopic groove 13. The telescopic arm 14 is slidably engaged with the telescopic groove 13. A tension spring is fixedly connected inside the telescopic groove 13, and one end of the tension spring is fixedly connected to the telescopic arm 14.

[0030] Specifically, a wrist strap 15 and a handle 16 are fixedly installed on the telescopic arm 14, with the handle 16 located above the wrist strap 15.

[0031] Specifically, the traction assembly includes a first fixed pulley 17 and a second fixed pulley 18 fixedly mounted on the mounting arm 4, with traction ropes 6 wrapped around the sides of both the first fixed pulley 17 and the second fixed pulley 18.

[0032] Specifically, one end of the traction rope 6 is fixedly connected to several counterweights 7, and the other end of the traction rope 6 passes through the mounting arm 4 and is fixedly connected to the movable arm 5.

[0033] As can be seen from the above, this device, by setting up a stand plate 1 with a traction component, allows patients to stand on the base 2 after shoulder joint surgery and need to undergo rehabilitation training. They can pass their wrists through the wrist fixation strap 15, hold the handle 16, bend their forearms downwards, and pull the counterweight 7 through the first fixed pulley 17 and the second fixed pulley 18. This can train the longitudinal traction ability of the shoulder.
