Technical Field

[0002] Shoulder arthroscopy is a core technology in sports medicine. It allows for intra-articular exploration and treatment through a minimally invasive 0.6cm incision. Its development began in the late 1980s and has become the preferred diagnostic and treatment option for conditions such as rotator cuff injuries and labral tears. This technique utilizes multiple surgical approaches, including a posterior-posterior approach and anterior-superior approach. Combined with specialized instruments such as transparent cannulas and radiofrequency vaporizers, it can perform high-precision procedures such as acromioplasty and tendon transfer in the lateral or beach-chair position.

[0003] Currently, during shoulder arthroscopic surgery, medical staff are often required to pull and rotate the patient's arm so that the shoulder joint can be better exposed. However, since surgical treatment often takes a certain amount of time, long-term traction by medical staff is not only prone to fatigue and a heavy workload, but also difficult to effectively restrain and stabilize, and is prone to tremors that affect surgical operations, thereby greatly affecting safety and resulting in poor results.

[0036] The fixing assembly includes a stud 29 screwed to the bottom end of the U-shaped holder 28, a handle 30 is fixed to the bottom end of the stud 29, and the top end of the stud 29 extends into the U-shaped holder 28 and is movably connected to a pressure plate 31 through a bearing.

[0037] The top side of the pressing plate 31 is provided with a rubber pad 32. Based on this, the pressing effect can be greatly enhanced by the rubber pad 32.

[0038] When in use, the device can be moved to the head of the operating bed, and by clamping the two U-shaped clamps 28 on the bedside and turning the handle 30 at the bottom end of the U-shaped clamp 28, the handle 30 can drive the stud 29 to rotate, and then the stud 29 can drive the pressure plate 31 to move and press against the bottom side of the bedside, so that the U-shaped clamp 28 can be clamped on the bedside, and then the device can be fixedly installed on the operating bed.

[0039] The adjustment mechanism includes slots 24 symmetrically opened on both sides of the top of the fixing frame 1. The two ends of the connecting frame 2 can be respectively inserted into the two slots 24.

The side walls of the two sides of the connecting frame 2 are symmetrically provided with multiple groups of positioning holes 25 that match the fixed knobs 27.

[0040] By pushing and pulling the connecting frame 2, the end of the connecting frame 2 can be slid in the slot 24 on the fixing frame 1. After moving, the fixing knob 27 on the threaded hole 26 can be tightened so that the end of the fixing knob 27 is inserted into the corresponding positioning hole 25, and the connecting frame 2 and the fixing frame 1 can be locked and fixed. The height position of the pull ring mechanism can be adjusted according to needs to better adapt to the patient's use, which greatly improves the applicability of the device.

[0046] The two clamping rings 20 are arranged in a staggered manner, and the inner sides of the clamping rings 20 are provided with anti-slip convex patterns.

[0047] When in use, the moving assembly can be started to drive the moving block 17 to move up and down in the frame 16, and then the moving block 17 can drive the push-pull rods 19 on both sides to rotate, so that the push-pull rods 19 drive the limiting arms 18 to rotate, and then the limiting arms 18 can drive the clamping rings 20 to move, so that the two clamping rings 20 are closed or opened. By controlling the opening and closing of the clamping rings 20, the distance between the two clamping rings 20 can be adjusted according to the thickness of the patient's arm, so that the arm can be effectively restrained between the two clamping rings 20;

[0048] Then the driving component can be started, and the slider 5 can be slid back and forth in the sliding cavity 4 through the driving component, and then the slider 5 can drive the support arm 6 to rotate through the connecting arm 7, and then the support arm 6 can drive the support column 8 to move, so that the support column 8 drives the guide column 11 to slide along the arc guide groove 10, so that the support column 8 can drive the pull ring mechanism to move up and down along the arc trajectory, and the patient's arm can be pulled by the pull ring mechanism to rotate slowly, thereby effectively assisting shoulder arthroscopic surgery.

The moving block 17 is screwed onto the outside of the second threaded rod 21. Based on this, the second motor 22 drives the second threaded rod 21 to rotate forward and reverse, which in turn drives the moving block 17 to slide up and down within the frame 16.
