Technical Field
[0001] This utility model relates to the field of support technology, and in particular to a positional fixation support for closed reduction surgery of supracondylar fracture of the humerus. Background Technology
[0002] A supracondylar fracture of the humerus refers to a fracture of the distal part of the humerus near the elbow joint. This type of fracture is more common in children. Closed reduction refers to manually reducing the fracture site to its normal position without cutting the skin.
[0003] During closed reduction surgery for supracondylar fracture of the humerus, the surgeon's assistant needs to hold and fix the patient's arm to facilitate the surgeon's operation. Over time, the surgeon's assistant will be continuously exposed to radiation, which will cause damage to the body. Moreover, holding the arm for too long can easily lead to fatigue and loss of reduction. Traditional surgical positioning and fixation devices are very complex in structure, expensive and inconvenient to operate.
[0004] To address the aforementioned issues, this utility model proposes a positioning fixation bracket for closed reduction surgery of supracondylar fractures of the humerus. Utility Model Content
[0005] This invention provides a positioning fixation bracket for closed reduction surgery of supracondylar fracture of the humerus, which solves the problems of existing technologies where, during closed reduction surgery of supracondylar fracture of the humerus, a doctor's assistant needs to hold and fix the patient's arm to facilitate the operation of the surgeon. However, this can lead to continuous exposure of the doctor's assistant to radiation over time, causing harm to the body. Furthermore, prolonged holding can cause fatigue and loss of reduction. In addition, traditional surgical positioning fixation devices are very complex in structure, expensive, and inconvenient to operate.
[0006] This utility model provides the following technical solution:
[0007] A positioning fixation frame for closed reduction surgery of supracondylar fracture of the humerus, comprising:
[0008] A U-shaped clamping seat is provided with a main rod above the U-shaped clamping seat, and a forearm grip and an upper arm grip are arranged sequentially from top to bottom on the main rod;
[0009] The first adjustment component, located on the U-shaped clamp, is used to adjust the position of the main rod to adapt to the placement and fixing requirements;
[0010] The second adjustment component, located on the main rod, is used to adjust the position and tilt of the forearm grip and upper arm grip to further adapt to placement and fixation requirements.
[0011] In one possible design, the first adjustment assembly includes a hinge frame fixedly mounted on the top of the U-shaped clamp, the main rod being rotatably mounted on the hinge frame by welded bolts, and the other end of the bolts being threaded with a nut for locking the position of the main rod.
[0012] In one possible design, the adjustment assembly includes two collars slidably mounted on the main rod, the collars being locked to the main rod by a threaded second bolt.
[0013] In one possible design, a corresponding support rod is fixedly installed on the outer wall of the collar, and a hard block is fixedly installed on the outer wall of both the forearm grip and the upper arm grip. A screw is fixedly installed in the center of the hard block, and the support rod is provided with a limiting sliding hole for the lateral movement of the corresponding screw. The other end of the screw passes through the limiting sliding hole and is threadedly connected to a locking cap for locking the tilt.
[0014] In one possible design, both the forearm grip and the upper arm grip include a sheath and a strap, the sheath being a rigid material that facilitates support for the arm, and the sheath having a soft inner lining.
[0015] In one possible design, the bottom of the U-shaped clamp is threaded with a first bolt, the top of which penetrates the inner wall of the U-shaped clamp and is fixedly fitted with a rubber block.
[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.
[0017] The working principle and usage process of this technical solution are as follows:
[0018] Before use, the U-shaped clamp should be simulated and adjusted on the healthy limb before surgery. In specific operation, place the U-shaped clamp in an appropriate position on the operating table or treatment table. By rotating the first bolt, the rubber block is tightly attached to the operating table or treatment table to achieve a stable fixation of the U-shaped clamp. Loosen the nut to allow the main rod to rotate freely on the articulated frame. According to the patient's body shape and surgical needs, rotate the main rod to a suitable position and then tighten the nut to lock the position of the main rod and prevent it from moving.
[0019] Then loosen the second bolt to allow the collar to slide freely on the main rod. Slide the collar to the desired position for the forearm grip and upper arm grip, then loosen the locking cap to allow the forearm grip and upper arm grip to freely adjust their tilt within the limiting slide hole of the support rod. Once the tilt is adjusted to the appropriate position, tighten the locking cap and the second bolt to lock the position and tilt of the forearm grip and upper arm grip. Then place the patient's arm into the sheath of the forearm grip and upper arm grip respectively, and secure it with straps to achieve fixed support for the arm.
[0020] This utility model has the following beneficial effects:
[0021] This invention can fix the position of surgical patients, reduce the risk of radiation exposure to assistants and doctors, and has a simple and convenient overall structure. It is easy to operate, and doctors can quickly complete the fixation of patients and surgical preparation, improving surgical efficiency. Moreover, it can be folded and stored after disassembly.
[0022] This invention ensures the stable fixation of the patient's arm during surgery through a sturdy U-shaped clamping seat and adjustable main rod, forearm grip, and upper arm grip, reducing surgical risks caused by patient movement. Furthermore, the position and inclination of the forearm and upper arm grips can be precisely adjusted according to the patient's body shape and surgical needs, helping doctors to better perform fracture reduction operations and improve surgical precision.

[0033] U-shaped clamp 1, with a main rod 2 above it. From top to bottom, a forearm grip 12 and an upper arm grip 11 are arranged on the main rod 2. Both the forearm grip 12 and the upper arm grip 11 include a rigid sheath and a strap. The sheath is made of a rigid material that can support the arm, such as plastic or lightweight metal, and has a soft inner lining, such as sponge or soft fabric, to increase patient comfort. The strap is used to fix the patient's arm to the grip device to ensure stability during the operation.
[0034] The first adjustment component, located on the U-shaped clamp 1, is used to adjust the position of the main rod 2 to adapt to the placement and fixation requirements. The first adjustment component includes a hinge frame 5 fixedly installed on the top of the U-shaped clamp 1. The lower end of the main rod 2 is rotatably connected to the hinge frame 5 by a welded bolt 6, so that the main rod 2 can rotate around the axis of the bolt 6 within a certain range to adapt to different patient body shapes and surgical needs. The other end of the bolt 6 is threaded with a nut 7. By rotating the nut 7, it can be made to fit tightly against the outer wall of the hinge frame 5, thereby locking the position of the main rod 2 and preventing it from moving during the operation.
[0035] The second adjustment component, located on the main rod 2, is used to adjust the position and tilt of the forearm grip 12 and the upper arm grip 11 to further adapt to the placement and fixation requirements. The adjustment component includes two collars 10 slidably mounted on the main rod 2. The collars 10 can slide freely along the length of the main rod 2 to adjust the longitudinal position of the forearm grip 12 and the upper arm grip 11. The collars 10 can also rotate laterally to adjust the lateral position of the forearm grip 12 and the upper arm grip 11. Each collar 10 is threaded with a second bolt 16. By tightening the threaded second bolt 16, the position of the collar 10 can be locked to ensure that it will not slide during the operation.
[0036] A support rod 8 is fixed on the outer wall of the collar 10. Hard blocks 13 are fixed on the outer walls of the forearm grip 12 and the upper arm grip 11. A screw 14 is fixed in the center of the hard block 13. The support rod 8 is provided with a limiting slide hole 9 for the lateral movement of the screw 14. The other end of the screw 14 passes through the limiting slide hole 9 and is threadedly connected to a locking cap 15. The screw 14 passes through the limiting slide hole 9 and is locked by the locking cap 15, thereby realizing the tilt adjustment of the forearm grip 12 and the upper arm grip 11 and ensuring their stable fixation.
[0037] This application can be used for closed reduction surgery of supracondylar fractures of the humerus, or for other fields applicable to this application.
[0038] Example 2
[0039] An improvement based on Example 1: a positional fixation frame for closed reduction surgery of supracondylar fracture of the humerus, which is used in the field of medical auxiliary frames;
