AI Technical Summary
In existing double-loop plate surgeries for acromioclavicular joint dislocations, the lower loop plate has a small contact area with the coracoid process, which increases the tension of the loop rope during the patient's recovery process. This can cause the rope to embed into the coracoid process and result in bone damage.
A novel loop plate is designed, comprising a first part and a second part that are rotatably connected, and a restoring force is provided by an elastic element, so that its area is larger than that of a single part after unfolding, thereby reducing the pressure on the beak.
By increasing the unfolding area, damage to the coracoid process is reduced, surgical outcomes are improved, and secondary harm to the patient is avoided.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a novel loop plate. Background Technology
[0002] Acromioclavicular joint dislocation is a relatively serious shoulder injury, often accompanied by ligament rupture. Clinically, a double-loop plate with loops is commonly used for reduction surgery. Figure 4 As shown, the double-loop plate includes an upper loop plate and a lower loop plate, which are connected by loops. The upper loop plate is installed on the upper part of the clavicle, and the lower loop plate is installed on the lower part of the coracoid process. The upper and lower loop plates are tightened by the loops to reduce the dislocated clavicle.
[0003] Due to the limited diameter of the surgical opening, the width of the lower loop plate is often small, resulting in a small contact area with the coracoid process. After the lower loop plate is pulled by the loop and contacts the lower part of the coracoid process, as the patient gradually recovers and the mobility of the injured upper limb gradually increases, the tension of the lower loop plate under the loop becomes greater and greater, which may cause it to stick tightly to the lower part of the coracoid process or even embed itself in the coracoid process, causing damage to the bone.

[0021] The following is in conjunction with the appendix Figure 1-4 This document provides a detailed description of the specific embodiments of this utility model. These embodiments are exemplary and intended only to explain the present utility model, and should not be construed as limiting the scope of the present utility model. Clearly, the embodiments described in this utility model are merely a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0022] The terms "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of the present invention include the specific features, structures, or characteristics described in connection with that embodiment. Therefore, the terms "comprising," "including," "having," and variations thereof in this specification mean "including but not limited to," unless otherwise specifically emphasized.
[0023] like Figure 1 As shown, the novel loop plate of the first embodiment of this utility model includes a first part 1 and a second part 2. The first part 1 and the second part 2 can be made of metal such as stainless steel, titanium, titanium alloy, etc., and the shape can be rectangular. Preferably, the first part 1 and the second part 2 have the same shape and the same size.
[0024] The long side of the first part 1 and the long side of the second part 2 are connected by a pivot, so that the first part 1 and the second part 2 can rotate relative to each other and be in a closed or unfolded state.
[0025] The first part 1 and the second part 2 are also connected by a reset member, which may be one or more, preferably an elastic member, such as... Figure 1 As shown, there are two elastic elements, which are connected to the upper and lower parts of the first part 1 and the second part 2, respectively.
[0026] The elastic element can be a spring, with the first end of the first spring 6 fixedly connected to the upper part of the first part 1 and the second end of the first spring 6 fixedly connected to the upper part of the second part 2; the first end of the second spring 7 fixedly connected to the lower part of the first part 1 and the second end of the second spring 7 fixedly connected to the lower part of the second part 2.
[0027] When the first part 1 and the second part 2 are engaged, the first spring 6 and the second spring 7 are compressed, providing an unfolding elastic force for the first part 1 and the second part 2.
[0028] The first part 1 has at least one first sleeve 11 on the edge of its long side, and the second part 2 has at least one second sleeve 21 on the edge of its long side. The first sleeve 11 and the second sleeve 12 are staggered in the length direction. The pivot 3 is inserted into the first sleeve 11 and the second sleeve 12 so that they can pivot.
[0029] The first part 1 has a first loop hole 5 (which is a through hole) in the upper part and a second loop hole 4 (which is a through hole) in the lower part, and the second part 2 has a second loop hole 4 (which is a through hole) in the upper part and a second loop hole 4 in the lower part. Preferably, the first loop hole 5 and the second loop hole 4 are set in corresponding positions.
[0030] The aforementioned new type of loop plate is a lower loop plate.
[0031] like Figure 2 The image shows a second embodiment of the novel loop plate of this utility model. Its main structure is basically the same as that of the first embodiment, with the main difference being the structure of the resetting member. Figure 2 In this process, the reset component is also an elastic component, preferably a spring. A first spring 6 and a second spring 7 are respectively provided in the first sleeve 11 and the second sleeve 12. The first spring 6 and the second spring 7 are sleeved on the rotating shaft 3, with one end connected to the rotating shaft 3 and the other end connected to the first sleeve 11 and the second sleeve 12.
[0032] When the first part 1 and the second part 2 are engaged, the first spring 6 and the second spring 7 are deformed by force, providing an unfolding elastic force for the first part 1 and the second part 2.
[0033] like Figure 3 As shown, this is the third embodiment of the novel loop plate of this utility model. Its main structure is basically the same as that of the first embodiment, with the main difference being the structure of the rotating structure and the resetting member. Figure 3 As shown, the first part 1 and the second part 2 are stacked on top of each other in a cross shape, with an acute angle or a right angle, preferably a right angle. The first part 1 and the second part 2 are connected to each other by a rotating shaft 3 inserted into a rotating shaft through hole in the overlapping part of the two parts, so that the two parts can rotate horizontally. A reset component, such as an elastic component, is fitted on the rotating shaft 3. The elastic component is a spring (not shown in the figure), one end of which is connected to the rotating shaft and the other end of which is connected to the rotating shaft hole. After the first part 1 and the second part 2 rotate and overlap, the spring is deformed by force, providing elastic force for the first part 1 and the second part 2 to return to their original cross shape.
[0034] Similar to embodiment 1, the elastic element can be a spring, with the first end of the first spring 6 fixedly connected to the first side of the first part 1 and the second end of the first spring 6 fixedly connected to the first side of the second part 2; the first end of the second spring 7 fixedly connected to the second side of the first part 1 and the second end of the second spring 7 fixedly connected to the second side of the second part 2.
[0035] like Figure 3 As shown, the first part 1 and the second part 2 form a cross shape when the elastic element is not deformed. Alternatively, they can also form an L-shaped cross or an X-shaped cross.
[0036] When using the novel loop plate, the first and second parts are first aligned or rotated to overlap, clamped with a clamp, and inserted along the hole opened on the clavicle. After reaching the predetermined position, the clamp is released, and the first and second parts unfold under the action of the repositioning component. The unfolded area is larger than the area of a single first or second part. It is tightened at the lower part of the coracoid process by the loop rope passing through the loop rope hole. Because the unfolded area is large, it is less likely to cause damage to the coracoid process, avoiding secondary injury to the patient after surgery and improving the surgical outcome.
[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
