[0002] Shoulder arthroscopy is a minimally invasive procedure that involves inserting an arthroscope into the joint cavity through a tiny incision around the shoulder joint for examination and treatment. This minimally invasive procedure requires the patient to lie in a side-lying position, using an auxiliary traction device to open the joint space of the shoulder joint for positioning before the surgical procedure can be performed.

[0003] China's authorization announcement number CN212140492U discloses an adjustable shoulder arthroscopy bedside traction device, which is configured as a cantilever beam traction device. The cantilever beam traction device is provided with a fixer, a longitudinal rod, a long-arm transverse rod, a short-arm transverse rod and a threaded angle fine-tuning rocker. The longitudinal rod is fixedly connected to the fixer, and the long-arm transverse rod and the short-arm transverse rod are movable through the longitudinal rod. The long-arm transverse rod and the short-arm transverse rod are respectively connected to the threaded angle fine-tuning rocker. Through the adjustment of the threaded angle fine-tuning rocker, the long-arm transverse rod and the short-arm transverse rod are made to move as a connecting rod to adjust the traction direction and traction force. The traction of the adjustable shoulder arthroscopy bedside traction device is stable and reliable, the traction process is easy to operate, and it can well cooperate with the continuous and stable traction required for shoulder joint surgery, so that the shoulder joint field of view is fully displayed, and the traction angle can be changed at any time, thereby saving operation time and effectively preventing contamination of the surgical area.

[0004] However, this device has the following drawbacks: while the traction angle can be adjusted at any time, the threaded angle fine-tuning rocker, long-arm transverse rod, and short-arm transverse rod are designed as an integrated unit that cannot be folded and stored, thus taking up too much space when not in use. To address these drawbacks, we propose a shoulder joint surgical positioning device. Utility Model Content

[0033] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a shoulder joint surgery positioning device of the present invention in conjunction with the accompanying drawings.

[0034] like Figure 1-5As shown, a shoulder joint surgical positioning device of the present invention includes: a support frame, a support structure, a fixing component and a pulling structure.

[0035] The support frame includes a vertical pole 1, a turntable 2 rotatably mounted on the upper end of the vertical pole 1, and a cross bar hinged to the outer surface of the turntable 2, and the cross bar is composed of a telescopic frame 3 and a telescopic rod 21 slidably connected to the inner wall of the telescopic frame 3. The lower surface of the telescopic frame 3 is threadedly connected with a locking bolt 19 that can lock the telescopic rod 21. The threaded end of the locking bolt 19 extends to the interior of the telescopic frame 3. Tightening the locking bolt 19 can drive the threaded end of the locking bolt 19 to press against the telescopic rod 21, thereby locking the telescopic rod 21.

[0036] The supporting structure includes a sliding seat 4 sleeved on the surface of the vertical pole 1, a rotating disk 5 rotatably installed on the top of the sliding seat 4, and a support rod 6 hinged on the lower surface of the telescopic frame 3. The surface of the sliding seat 4 is threadedly connected with a fixing bolt 20 that can lock the rotating disk 5. The threaded end of the fixing bolt 20 overlaps the lower surface of the rotating disk 5. Tightening the fixing bolt 20 can drive the threaded end of the fixing bolt 20 to tighten the rotating disk 5, thereby locking the rotating disk 5 and preventing the cross bar from rotating.

[0037] The fixing assembly is arranged between the sliding seat 4 and the upright pole 1. The fixing assembly includes a straight rack 16 fixedly mounted on the right side of the upright pole 1. A pin 17 compatible with the straight rack 16 is inserted on the right side of the sliding seat 4. The left end of the pin 17 extends to the interior of the sliding seat 4. The surface of the pin 17 is provided with a tension spring 18 that can insert the pin 17 into the inner wall of the tooth groove of the straight rack 16. When the pin 17 is inserted into the tooth groove in the straight rack 16, the pin 17 can be used to limit the sliding seat 4 to prevent the sliding seat 4 from falling. At the same time, the pin 17 is inserted into the tooth groove of the straight rack 16 at different positions, so as to change the height of the sliding seat 4.

[0038] An assembly component that can be assembled with the rotating disk 5 is provided at one end of the support rod 6 close to the rotating disk 5. The assembly component includes a through groove opened on the surface of the support rod 6, an assembly pin 13 slidably installed on the inner wall of the through groove, and a plug-in rack 14 fixedly installed on the upper end of the rotating disk 5. The inner wall of the plug-in rack 14 is provided with an assembly hole that is compatible with the assembly pin 13, and the interior of the through groove is provided with a compression spring 15 that can drive the assembly pin 13 to insert into the inner wall of the assembly hole.

[0039] After the assembly pin 13 is inserted into the assembly hole, the assembly pin 13 and the assembly hole are rotationally connected. At the same time, one end of the support rod 6 will be assembled with the rotating disk 5 as a whole, so that the cross bar can be unfolded using the support rod 6. Conversely, pressing the assembly pin 13 drives the compression spring 15 to contract. At this time, the assembly pin 13 will be disengaged from the assembly hole, so that the support rod 6 can be taken out of the socket rack 14. After being disengaged from the support of the support rod 6, the cross bar will rotate to be folded and stored, thereby facilitating the storage of the device and saving space.

[0040] The rotating disk 5 is arranged to be rotatably connected to the sliding seat 4, and the cross bar is hinged to the rotating disk 2. When the rotating disk 5 is rotated, the cross bar is driven to rotate along with it by the pulling of the support rod 6. When the height of the sliding seat 4 is changed, the support rod 6 drives the cross bar to rotate, thereby changing the angle of the cross bar, and then the cross bar can be flexibly adjusted according to the patient's arm position.

[0041] The pulling structure is arranged on the surface of the support frame, and the pulling structure includes pulleys 7 respectively arranged at the upper end of the turntable 2 and the right end of the telescopic rod 21, and a pulling rope 8 slidably installed on the surface of the two pulleys 7. A strap 9 is fixedly installed at one end of the pulling rope 8, and a counterweight assembly is fixedly installed at the other end of the pulling rope 8. A through hole for the pulling rope 8 to pass through is provided on the surface of the rotating disk 5. The counterweight assembly includes a limiting rod 10 fixedly installed at one end of the pulling rope 8, and a tray 11 fixedly installed at the lower end of the limiting rod 10. A weight 12 is placed on the upper surface of the tray 11, and an open groove is provided on the surface of the weight 12 for the limiting rod 10 to pass through.

[0042] After the strap 9 is tied to the patient's arm, weights 12 of different weights can be placed on the tray 11. The weight of the weights 12 can be used to drive the traction rope 8 to pull and fix the patient's arm, thereby opening the joint space of the patient's shoulder joint for positioning.

[0043] It is understood that the present invention is described by way of certain embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. Furthermore, under the guidance of the present invention, these features and embodiments may be modified to suit specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are intended to be protected by the present invention.
