Description

Technical Field

[0001] This utility model relates to the field of acromioclavicular joint dislocation reduction technology, and in particular to the acromioclavicular joint dislocation reduction channel structure. Background Technology

[0002] Acromioclavicular joint dislocation is not uncommon, and may present with local pain, swelling, and tenderness. Abduction or elevation of the injured limb is difficult, and flexion and extension movements are also limited. Local pain is exacerbated. During examination, a depression can be felt at the acromioclavicular joint, and joint loosening can be detected. Manual reduction followed by immobilization is difficult, resulting in a high surgical rate. In patients with complete acromioclavicular joint dislocation (Type III injury), the joint capsule, acromioclavicular ligament, and coracoclavicular ligament are all ruptured, causing complete instability of the acromioclavicular joint. External fixation is ineffective in these cases, and surgical repair is recommended for patients under 45 years of age. Commonly used surgical methods include open reduction and internal fixation of the acromioclavicular joint, coracoclavicular ligament reconstruction or fixation, lateral clavicle resection, and muscle dynamic reconstruction.

[0003] Some existing acromioclavicular joint dislocation reduction devices typically use two loop plates to apply pressure and fix the bone during the reduction process. The operation of positioning the loop plates is cumbersome, which not only increases the difficulty of the operation, but also easily causes secondary damage to the patient and causes local discomfort at the wound site after the operation. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing acromioclavicular joint dislocation reduction devices, which typically use two loop plates to pressurize and fix the bone during the reduction process. The operation of the loop plates during positioning is cumbersome, which not only increases the difficulty of the operation, but also easily causes secondary damage to the patient and causes local discomfort at the wound site after surgery. This invention provides an acromioclavicular joint dislocation reduction channel structure.

[0005] The purpose of this utility model is achieved through the following technical solution: a reduction channel structure for acromioclavicular joint dislocation, including a clavicle channel cannula, an upper loop steel plate and a lower loop steel plate, the upper loop steel plate and the lower loop steel plate are connected by a loop line, the upper loop steel plate and the lower loop steel plate are located above and below the clavicle channel cannula respectively, and the loop line passes through the middle of the clavicle channel cannula;

[0006] The clavicular cannula is tapered, and an opening groove is provided on the side of the clavicular cannula. By setting the clavicular cannula, the inferior loop plate can easily pass through the clavicle to reach the position where the coracoid process needs to be reduced, thus reducing the difficulty of the operation. Furthermore, the inferior loop plate can directly reach the predetermined area through the clavicular cannula, reducing damage to the patient's tendons during the operation and reducing postoperative discomfort.

[0007] A further technical solution is to have a U-shaped groove on the upper part of the lower loop steel plate, through which the loop wire passes through the lower loop steel plate. By setting the U-shaped groove, the loop wire can drive the lower loop steel plate to press the coracoid process upward, so that the coracoid process and clavicle are repositioned. The structure is simple and easy to operate.

[0008] A further technical solution is that the upper loop steel plate is provided with tightening holes, and the bottom of the upper loop steel plate is provided with two sets of through holes that are connected to the inner wall of the tightening holes. The two ends of the loop are respectively connected through the two sets of through holes.

[0009] A further technical solution involves installing a threaded cap inside the tightening hole, with a pressure block at the bottom of the threaded cap that contacts the loop. By controlling the tightening of the threaded cap inside the tightening hole, the pressure block presses the loop downward, thereby adjusting the tension of the loop and ensuring the accuracy of the coracoid process and clavicle repositioning. At the same time, it can close the loop within the clavicle channel, reducing the contact between the clavicle and the tendon and reducing postoperative discomfort.

[0010] A further technical solution is to install positioning holes for installing bone screws on the upper loop steel plate, which facilitates the fixation of the upper loop steel plate.

[0011] This invention has the following advantages: By setting a clavicle channel cannula, the lower loop plate can easily pass through the clavicle to reach the position where the coracoid process needs to be reduced, thus reducing the difficulty of the operation. Furthermore, the lower loop plate can directly reach the predetermined area through the clavicle channel cannula, reducing damage to the patient's tendons during the operation and reducing postoperative discomfort. By controlling the tightening of the threaded cap in the tightening hole, the pressure block is pressed downward to tighten the loop line, thereby adjusting the tension of the loop line and ensuring the accuracy of the coracoid process and clavicle reduction. At the same time, the loop line can be closed within the clavicle channel, reducing the contact between the clavicle and the tendons and reducing postoperative discomfort.

[0022] like Figures 1-3As shown, the acromioclavicular joint dislocation reduction channel structure includes a clavicle channel cannula 1, an upper loop plate 2, and a lower loop plate 3. The upper loop plate 2 and the lower loop plate 3 are connected by a loop line 4. The upper loop plate 2 and the lower loop plate 3 are located above and below the clavicle channel cannula 1, respectively, and the loop line 4 passes through the middle of the clavicle channel cannula 1.

[0023] The clavicle channel cannula 1 is conical, and an opening groove 8 is provided on the side of the clavicle channel cannula 1. By setting the clavicle channel cannula 1, the lower loop plate 3 can easily pass through the clavicle 13 to reach the position where the coracoid process 14 needs to be reduced, thus reducing the difficulty of the operation. Furthermore, the lower loop plate 3 can directly reach the predetermined area through the clavicle channel cannula 1, reducing damage to the patient's tendons during the operation and reducing postoperative discomfort.

[0024] The lower loop steel plate 3 has a U-shaped groove 6 on its upper part. The loop wire 4 passes through the lower loop steel plate 3 through the U-shaped groove 6. By setting the U-shaped groove 6, the loop wire 4 can drive the lower loop steel plate 3 to press the beak protrusion 14 upward, so that the beak protrusion 14 and the clavicle 13 are reset. The structure is simple and easy to operate. The upper loop steel plate 2 is provided with a tightening hole 7. The bottom of the upper loop steel plate 2 is provided with two sets of through holes 9 that are connected to the inner wall of the tightening hole 7.

[0025] A threaded cap 11 is installed in the internal thread of the tightening hole 7. A pressure block 12 that contacts the loop 4 is installed at the bottom of the threaded cap 11. By controlling the tightening of the threaded cap 11 in the tightening hole 7, the pressure block 12 presses the loop 4 downward, thereby adjusting the tension of the loop 4 and ensuring the accuracy of the repositioning of the coracoid process 14 and the clavicle 13. At the same time, the loop 4 can be closed in the channel of the clavicle 13, reducing the contact between the clavicle 13 and the tendon and reducing postoperative discomfort.
