[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] Please see Figure 1This utility model provides an upper limb skin traction-assisted manual reduction device, including a strip frame 1, a wrist support 3, and positioning rods 4. Each of the two opposite corners of one end of the strip frame 1 has an upwardly extending limiting rod 2, which is positioned to abut against the surgeon's armpit to prevent displacement of the surgeon's torso during traction. Furthermore, the outer periphery of the limiting rod 2 is covered with a flexible padding layer to reduce pain caused by force on the surgeon's armpit. The strip frame 1 of this application is a rectangular frame structure welded from square or round tubes. The wrist support 3 is positioned on the inner side or top surface of the strip frame 1, allowing it to slide back and forth along its length. Multiple positioning rods 4 are positioned on both sides of the strip frame 1 along its length to position the traction band 5 during counter-traction. In particular, to enhance the stability of the device, a cushion 6 is provided at the end of the strip frame 1 away from the limiting rod 2, so that the doctor can sit on the cushion 6 when performing bedside manual repositioning, which is convenient for operation and can also prevent the device from sliding and shifting by the doctor's own weight.

[0024] When using this device, first place it flat on the bed and have the surgeon lie down, with the limiting rod 2 against the surgeon's armpit. Place the wrist support 3 on the wrist support 3 to support the arm. Then, place the traction strap 5 and pull it to the required tension before attaching it to the corresponding positioning rod 4. Using this device, only one doctor needs to independently complete the manual reduction, making full use of limited medical resources. In particular, this device can provide continuous traction before reduction, creating favorable conditions for manual reduction. After the surgeon has performed the manual reduction, the wrist support 3 can be slid to adjust its support point on the surgeon's arm, leaving sufficient space for splint or plaster fixation.

[0025] As a further improvement to the above solution, please refer to 1-2. The wrist rest 3 includes a sliding frame 31 and a bracket 33. Limiting grooves 32, such as C-grooves or T-grooves, are provided on opposite sides of the sliding frame 31 for sliding connection with the inner side of the strip frame 1. Obviously, sliding strips can also be provided on the strip frame 1 to cooperate with the limiting grooves 32. The bracket 33 is fixedly connected to the top surface of the sliding frame 31. Generally, the outer periphery of the bracket 33 is also covered with a flexible padding layer. By providing the limiting grooves 32, the stability of the wrist rest 3 on the strip frame 1 is ensured. In one embodiment, the inner side of the strip frame 1 is provided with a U-shaped slide rod 11, and the two arms of the U-shaped slide rod 11 are slidably connected to the limiting slide grooves 32 on both sides of the slide frame 31. On the one hand, by replacing two slide bars with one U-shaped slide rod 11, the device is more convenient to manufacture; on the other hand, when the device is not in use, it can be stored upright, such as in a storage cabinet. The closed end (i.e., the bent part) of the U-shaped slide rod 11 can effectively prevent the wrist rest 3 from slipping off. In addition, if the actual supporting part of the bracket 33 is eccentrically set relative to the entire wrist rest 3, i.e. Figure 2As shown, depending on actual needs, the wrist rest 3 can also be easily detached from the open end of the U-shaped slide bar 11, rotated 180 degrees, and then reconnected to the U-shaped slide bar 11. The unused portion of the bracket 33 then functions as a handle. Obviously, in practical use, the wrist rest 3 can also be separated from the U-shaped slide bar 11 as needed, such as by placing the wrist rest 3 directly in a suitable position on the strip frame 1. However, since the wrist rest 3 is not connected to the limiting slide groove 32, its stability is slightly lower.

[0026] As a further improvement to the above solution, the positioning rod 4 and the strip frame 1 can be connected in an assembly manner, i.e., please refer to [link to relevant documentation]. Figure 2 All positioning rods 4 located on the same side of the strip frame 1 pass through the strip frame 1 and are fixedly connected to the rod base 41 located on the bottom side of the strip frame 1. Preferably, the rod base 41 can be detachably connected to the strip frame 1 by bolts, thereby making the rod base 41 and the multiple positioning rods 4 integrally set, which is convenient for modular production. Obviously, the positioning rods 4 can also be directly and evenly welded to both sides of the strip frame 1. In addition, the positioning rods 4 generally need to be set at an angle, with their angle direction opposite to the wrist rest 3.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
