Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and more specifically relates to a fully sutured riveted composite adjustable loop titanium plate device for acromioclavicular joint reconstruction. Background Technology

[0002] The acromioclavicular joint is a joint formed by the lateral end of the clavicle and the acromion, fixed by structures such as the articular ligament, acromioclavicular ligament, and clavicular ligament to maintain joint stability. When the acromioclavicular joint is subjected to violent impact (such as shoulder landing or shoulder impingement), damage to the articular ligament, acromioclavicular ligament, and clavicular ligament can cause acromioclavicular joint dislocation. Clinically, it often presents with symptoms such as shoulder pain, local swelling, and limited shoulder joint movement. In recent years, with the development of shoulder arthroscopy and the application of flexible fixation techniques, the technique of using looped titanium plates to treat acromioclavicular joint dislocation has become increasingly mature. Various internal fixation methods have brought a series of complications related to internal fixation devices, such as acromial impingement after clavicle hook plate surgery, instability of the looped plate, overreduction or underreduction, infection, and bone tunnel resorption. Furthermore, most fixation methods require multiple bone tunnel creations and multiple suture guide pin and traction suture setups during surgery, making the traction suture group extremely complex, resulting in a cumbersome and lengthy operation.

[0003] Therefore, how to provide a safe and efficient fully sutured riveted composite adjustable loop titanium plate device for acromioclavicular joint reconstruction is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a fully sutured riveted composite adjustable loop titanium plate device for acromioclavicular joint reconstruction, adopting the following technical solution: A fully sutured rivet combined with an adjustable loop titanium plate device for acromioclavicular joint reconstruction includes a fully sutured rivet and a titanium plate; one end of the fully sutured rivet is riveted to the outer end of the clavicle, and the other end extends downward from the outer end of the clavicle through the soft tissue inside the acromioclavicular joint and extends upward from the underside of the acromion through the acromion to form an adjustable loop, which is connected to the titanium plate.

[0005] Furthermore, the full-suture rivet includes a fixing part and a traction part, the fixing part being fixed inside the clavicle; one end of the traction part is connected to the fixing part, and the other end is connected to a titanium plate.

[0006] Furthermore, the traction part includes a first suture and a second suture; the titanium plate is configured in a dog bone shape, and two sets of through holes are symmetrically arranged on the titanium plate, forming a crossbeam in the middle to connect the traction part; the through holes are set to open towards the edge of the titanium plate on the side away from the center of the titanium plate, for the passage of the first suture and the second suture.

[0007] Furthermore, a bone channel is pre-drilled at the acromion to house the traction unit; the traction unit passes through the bone channel from bottom to top and connects to the titanium plate; the first suture and the second suture are respectively inserted into the through hole through the opening at the edge of the titanium plate, and after crossing each other, they are inserted into the through hole again through the opening to form an adjustable loop.

[0008] The beneficial effects of this utility model are as follows: This invention provides a fully sutured rivet combined with an adjustable loop titanium plate device for acromioclavicular joint reconstruction. One end of the fully sutured rivet is riveted to the outer end of the clavicle, and the other end extends upward from the outer end of the clavicle, penetrating downward through the soft tissue within the acromioclavicular joint, and then upward through the acromion from the lower side to form an adjustable loop connecting the titanium plate. The fully sutured rivet forms an "N"-shaped structure from the clavicle to the acromion. The application of the fully sutured rivet combined with a canine bone-type titanium plate to treat acromioclavicular joint dislocation results in a smaller incision, shorter operation time, higher surgical efficiency, and a shorter patient recovery period, which has positive clinical significance.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see the appendix Figure 1-3This utility model provides a fully sutured rivet composite adjustable loop titanium plate device for acromioclavicular joint reconstruction, including a fully sutured rivet 1 and a titanium plate 2; one end of the fully sutured rivet 1 is riveted to the outer end of the clavicle 3, and the other end extends downward from the outer end of the clavicle 3 through the soft tissue inside the acromioclavicular joint, and extends upward from the lower side of the acromion 4 through the acromion 4 to form an adjustable loop, which is connected to the titanium plate 2.

[0016] The full-suture rivet 1 includes a fixing part and a traction part. The fixing part is fixed inside the clavicle 3. After drilling a hole at the end of the clavicle 3, an inserter is inserted into the hole. The fixing part is pushed into the bone channel by the push rod inside the inserter. Rotating the end of the inserter stimulates the fixing part to expand the suture coil and fix it in the bone channel to form the fixing part. After releasing the suture, the rivet rod is removed to complete the fixation of the full-suture rivet 1. One end of the traction part is connected to the fixing part, and the other end is connected to the titanium plate 2.

[0017] The traction part includes a first suture and a second suture, which connect to the titanium plate 2.

[0018] The titanium plate 2 is configured in a dog bone shape, and two sets of through holes are symmetrically arranged on the titanium plate 2, forming a crossbeam in the middle to connect the traction part; the through holes are set to open towards the edge of the titanium plate 2 on the side away from the center of the titanium plate 2, so as to facilitate the passage of the first and second stitches.

[0019] The traction unit penetrates the soft tissue within the acromioclavicular joint with the assistance of an integrated suture guide. A bone channel is pre-drilled at the acromion 4 for the installation of the traction unit. The traction unit connects to the titanium plate 2 through the bone channel from bottom to top. The first and second sutures are respectively inserted into the through-holes through openings on the edge of the titanium plate 2, cross each other, and then inserted into the through-holes again through openings to form an adjustable loop connecting the titanium plate 2. The end of the traction unit is knotted at the lower end of the acromion 4 through the bone channel to prevent suture protrusion. The traction unit forms an "N"-shaped structure from the clavicle 3 to the acromion 4. By tightening the ends of the first and second sutures, the titanium plate 2 can be pressed against the acromion 4, pulling the acromion 4 and clavicle 3 to produce relative displacement, thereby restoring the dislocation.

[0020] This invention utilizes a combination of fully sutured rivets 1 and canine bone-shaped titanium plates 2 to treat acromioclavicular joint dislocation. The small incision and short operation time result in higher surgical efficiency and a shorter patient recovery period, demonstrating significant clinical value.
