Problems solved by technology

[0005] In view of the above-mentioned related technical solutions, the inventors found that although titanium alloy or other metal materials with belt loops meet the strength and stiffness requirements of the repair structure in sports medicine operations such as shoulder joint dislocation, it is also because of this that the belt loops The titanium plate cannot be deformed in the process of passing through the through hole opened on the clavicle 1 and the coracoid process 2, so the diameter of the through hole needs to be larger to allow the titanium plate with loops to pass through, which results in a larger bone removal process. amount and may cause greater iatrogenic damage

Embodiment 1

[0045] refer to figure 2 , the application provides an acromioclavicular joint repair device, comprising a first loop plate member 6 made of elastic material and a second loop plate member 7 made of elastic material; the first loop plate member 6 and the second loop plate member 7 A tail line 5 is arranged between the 7, and when the tail line 5 is pulled, the first loop board member 6 and the second loop board member 7 can move toward each other in a direction close to each other; The shape is annular and the structure of the first loop plate member 6 is an inner hollow tubular structure; the shape and structure of the second loop plate member 7 and the first loop plate member 6 are the same, and the difference between the two is only the difference in the installation position, The details are not repeated here; the area enclosed by the inner circle contour of the first flap member 6 and the area enclosed by the inner circle outline of the second flap member 7 form the defo...

Embodiment 2

[0056] refer to Image 6 , the difference between this embodiment and the first embodiment is that the first loop plate member 6 is provided with a first thread hole 65 and a second thread hole 66 distributed along the circumferential direction of the first loop plate member 6, and the second loop plate The member 7 is provided with a third threading hole 75 and a fourth threading hole 76 distributed along the circumferential direction of the second flap member 7 at intervals.

[0057] In this embodiment, the first threading hole 65 and the second threading hole 66 are respectively opened on both sides of the first loop plate member 6 and communicate with the inside of the first loop plate member 6; the third threading hole 75 and the fourth threading hole 76 are respectively opened on both sides of the second loop board member 7 and communicate with the inside of the second loop board member 7 .

[0058] The common point of the routing paths of the two tail wires 5 is that t...

Embodiment 3

[0061] refer to Figure 7 , the difference between this embodiment and the second embodiment is that the coiling method of the tail wire 5 on the first loop board member 6 and the second loop board member 7 is different.

[0062] It is further explained that a plurality of through holes distributed along the circumferential direction of the first loop board member 6 are provided on the inner side and the outer side of the first loop board member 6, and after the tail wire 5 enters the inside of the first loop board member 6, Passing through these through holes in turn enables the tail wire 5 to reciprocately penetrate into and out of the first loop member 6;

[0063] In this way, the number of connection parts between the first loop board member 6 and the tail wire 5 and between the second loop board member 7 and the tail wire 5 is increased. When the tail wire 5 is inside the first loop board member 6 and the second loop board When the inside of the piece 7 shrinks and becom...

Abstract

The present application relates to the field of acromioclavicular joint reduction therapy, in particular to a device for repairing acromioclavicular joints. The key points of the technical solution are: comprising a first loop made of an elastic material and a second loop made of an elastic material, There is at least one deformation hole on the first tab part and the second tab part; a tail line for making the two move toward each other is passed between the first tab part and the second tab part; The compression-deformability of the first tab piece allows the first tab piece to compress in size to pass through the openings in the clavicle and coracoid process, such that the openings are smaller in size than would be required for the metal plate , achieved the purpose of reducing the amount of bone removed during the reduction treatment operation to reduce iatrogenic damage.

Description

technical field [0001] The present application relates to the field of acromioclavicular joint reduction treatment, in particular to an acromioclavicular joint repair device. Background technique [0002] For the treatment of acromioclavicular joint dislocation in sports medicine, titanium plates with loops are generally used in pairs to fix the disengaged clavicle and coracoid process to achieve the reduction and treatment of the acromioclavicular joint. [0003] refer to figure 1 , the titanium plate with a loop recorded in the related art includes a metal plate 3 processed from a titanium alloy, and the metal plate 3 is provided with two tail wire holes 31 penetrating the titanium plate with a loop, and the two tail wire holes 31 are close to the metal plate 3 The middle position of the metal plate 3 is opened; the two tail holes 31 on the metal plate 3 are provided with pulling holes 32 on one side away from each other; A tail wire 5 is arranged between the two metal p...
