DETAILED DESCRIPTION
[0017] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with embodiments.
[0018] As Figure 1As shown, a shoulder dislocation reduction and compression wire passer includes a wire passing structure 10, an adjusting structure 20, and a longitudinal compression screw guide structure 30; the wire passing structure 10 is used to assist the wire to be arranged around the coracoid process; the wire passing structure 10 includes two wire passing handles 11, the two wire passing structures 10 are symmetrically arranged, the middle parts of the two wire passing structures 10 are hinged through a hinge structure 40, and the two wire passing structures 10 can rotate around the hinge structure 40; the adjusting structure 20 is connected through the first end of the wire passing structure 10; the adjusting structure is used to adjust the relative position and separation of the second end of the wire passing structure 10; the longitudinal compression screw guide structure 30 is radially connected through the adjusting structure 20, and the longitudinal compression screw guide structure 30 is used to guide the threaded Kirschner wire 50 to drill into the bone.
[0019] Among them, the distance between the first ends of the two wire passing handles 11 is greater than the distance between the second ends of the two wire passing handles 11; the two wire passing handles 11 rotate away from each other around the hinge structure 40 to the limit position, and the second ends of the two wire passing handles 11 are opposite to each other.
[0020] Specifically, the wire 60 is a synthetic absorbable surgical suture, under the condition of coracoid process exposure, in the horizontal direction, the side close to the neck is the medial side, and the side close to the shoulder is the lateral side, in use, first place the second end of the wire passing structure 10 at the bottom of the coracoid process, the medial side and the lateral side are the first wire passing handle 11 and the second wire passing handle 11 respectively, then make the wire 60 enter the first wire passing handle 11, and from the second end of the first wire passing handle 11 to the second end of the second wire passing handle 11, then lead out from the position close to the first end of the second wire passing handle 11, and accurately place the wire 60 at the bottom of the coracoid process through the opening between the second ends of the first wire passing handle 11 and the second wire passing handle 11.
[0021] The adjusting structure 20 is arranged at the first end of the wire passing structure 10, so that the operator can control the relative position and state of the second end of the wire passing structure 10 by adjusting the adjusting structure 20.
[0022] The first wire passing handle 11 and the second wire passing handle 11 are hinged by the hinge structure 40 between the first end and the second end of the wire passing structure 10. When the distance between the first end of the first wire passing handle 11 and the first end of the second wire passing handle 11 is expanded, the distance between the second end of the first wire passing handle 11 and the second end of the second wire passing handle 11 is reduced, and vice versa. In the process of placing the first wire passing handle 11 and the second wire passing handle 11 on both sides of the coracoid process, the distance between the first end of the first wire passing handle 11 and the first end of the second wire passing handle 11 is reduced by adjusting the structure 20 to expand the opening of the second end of the wire passing structure 10, so that the coracoid process can be smoothly placed between the hinge structure 40 and the second end of the wire passing structure 10, and the first wire passing handle 11 and the second wire passing handle 11 are respectively located on the inner and outer sides of the coracoid process, and the second ends of the first wire passing handle 11 and the second wire passing handle 11 are located below the coracoid process. Then when the lead wire 60 is inserted into the wire passing structure 10, the opening of the second end of the wire passing structure 10 can be reduced, so that the lead wire 60 can smoothly enter the second wire passing handle 11 from the first wire passing handle 11. In addition, due to individual differences, the shape and size of the coracoid process may be different, and the adjusting structure 20 allows the operator to adjust the position and angle of the wire passing handle 11 according to the specific situation of the patient, thereby ensuring that the shoulder joint dislocation reduction and compression wire passing device can be universal.
[0023] The threaded Kirschner wire 50 is a medical tool with threads for fixing bone fragments or connecting between bones, and threads are designed on the outer surface near the tip position to increase the contact area and friction between the Kirschner wire and the bone, thereby providing a more secure fixing effect. The longitudinal compression threaded guide structure 30 vertically penetrates the connection adjusting structure 20, and the second end of the longitudinal compression threaded guide structure 30 abuts against the clavicle during movement towards the wire passing structure 10, thereby achieving compression of the clavicle and reducing the clavicle to the position it occupies in the normal state. Then the threaded Kirschner wire 50 is moved along the longitudinal compression threaded guide structure 30 from the first end of the longitudinal compression threaded guide structure 30 to the second end of the longitudinal compression threaded guide structure 30, and is drilled into the clavicle from the point of compression of the clavicle at the second end of the longitudinal compression threaded guide structure 30. After removing the shoulder joint dislocation reduction and compression wire passing device, the threaded Kirschner wire 50 drilled through the clavicle can be further drilled into the coracoid process to connect the clavicle and the coracoid process, thereby maintaining the reduction effect of the clavicle. The longitudinal compression threaded guide structure 30 ensures the accurate insertion of the threaded Kirschner wire 50 during the operation.
[0024] The structures in this application are all made of metal, and in addition, a spring is provided at the hinge structure 40 to apply a force to the first end of the first wire passing handle 11 and the first end of the second wire passing handle 11.
[0025] In general, the adjusting structure 20 adjusts the opening and closing size of the second end of the threading structure 10, so as to facilitate and accurately thread the coracoid process with the threading handle 11. In addition, the longitudinal pressure screw guide structure 30 can achieve pressure and reduction of the clavicle, and the threaded Kirschner wire 50 is guided by the longitudinal pressure screw guide structure 30, so that the positioning is more accurate when drilling the bone tunnel, thereby facilitating the operation, saving the operation time, improving the success rate of the operation, and increasing the patient satisfaction.
[0026] In a possible implementation, the two threading handles 11 are arc-shaped hollow tubes; the internal space of the threading handle 11 is used for threading the wire; when the second ends of the two threading handles 11 are opposite, the wire from the second end of the first threading handle 11 enters the second end of the second threading handle 11 and is led out from the second threading handle 11.
[0027] Specifically, the arc-shaped surface of the threading handle 11 is smoother and is not easy to scratch or press the surrounding tissue, thereby reducing the risk of damage to the surrounding soft tissue during the operation. The hollow tube structure provides a stable channel for the wire 60, so as to ensure that the wire 60 can smoothly and accurately pass through the bottom of the coracoid process, thereby reducing the error during the operation. The wire 60 is sequentially threaded through the second ends of the two threading handles, so that the operator can more conveniently control the direction and tension of the wire, ensure the position of the wire 60 at the bottom of the coracoid process, and further help to reduce the crossing and winding of the wire, thereby improving the operation efficiency.
[0028] In a possible implementation, the threading structure 10 further comprises two short columns 12, which are hollow tubes and are respectively arranged on the outer side of each threading handle 11 and communicate with the inner cavity of the corresponding threading handle 11; the opening end of each short column 12 is above the connecting end of the short column 12.
[0029] Specifically, the two short columns 12 are hollow tubes and are respectively arranged on the outer side of each threading handle 11 and communicate with the inner cavity of the corresponding threading handle 11; the opening end of each short column 12 faces the outer side of the two threading handles 11, and the first end of each short column 12 is a free end for threading the wire 60 in and out, and the second end of each short column 12 is a connecting end connected with the corresponding threading handle 11, and the opening end of each short column 12 is above the connecting end, that is, the connecting end faces the second end of the threading structure 10. The short column 12 enables the operator to more conveniently thread the wire 60 in and out without deepening into the interior of the threading handle 11. Moreover, the opening end of each short column 12 is above the connecting end, so that the wire 60 is more smooth when being threaded in and out.
[0030] In a possible implementation, two first threaded holes are formed on the two wire passing handles 11, and the adjusting structure 20 includes a first threaded rod 21 and two first nuts 22. The first threaded rod 21 is inserted into the two first threaded holes at two ends, respectively, for adjusting the distance between the two wire passing handles 11. The two first nuts 22 are screwed on the first threaded rod 21, and each first nut 22 abuts against the inner side of the corresponding wire passing handle 11 to fix the position of the corresponding wire passing handle 11 on the first threaded rod 21.
[0031] Specifically, the two ends of the first threaded rod 21 are connected to the two wire passing handles 11 through the two first threaded holes, respectively. The inner surface of the first threaded hole is larger than the outer diameter of the first threaded rod 21, so that when the middle part of the two wire passing handles 11 rotates around the hinge structure 40 under the action of an external force, the first end of the two wire passing handles 11 can move on the first threaded rod 21, thereby adjusting the size of the opening at the second end of the wire passing structure 10. When the two wire passing handles 11 are adjusted to the appropriate position, the first nut 22 can abut against the inner side of the wire passing handle 11, thereby fixing the position of the wire passing handle 11 on the first threaded rod 21 and preventing it from moving during the operation.
[0032] In a possible implementation, the first end of the first nut 22 is columnar, and the outer surface of the first end is provided with threads. The second end of the first nut 22 is spherical to match the curved shape of the inner side of the corresponding wire passing handle 11 when the first nut 22 is tightened.
[0033] Specifically, the threads on the outer surface of the first end of the first nut 22 facilitate the operation of tools such as wrenches, screwdrivers, or special tightening tools. These tools can tightly match the threads, so that the operator can easily and efficiently tighten the nut, improving work efficiency. The second end of the first nut 22 is spherical, and the contact area between the second end of the first nut 22 and the inner side of the wire passing handle 11 is larger during the tightening process, and the pressure distribution is more uniform, which can reduce the damage or deformation of the components caused by pressure concentration, and at the same time improve the tightening effect.
[0034] In a possible implementation, a second threaded hole is formed on the first threaded rod 21 in the radial direction, and the longitudinal pressure threaded guide structure 30 includes a second threaded rod 31 and a second nut 32. The second threaded rod 31 is a hollow pipe, the second threaded rod 31 matches the second threaded hole, and the second threaded rod 31 is perpendicular to the first threaded rod 21. The second nut 32 is sleeved on the outside of the second threaded rod 31 through threads, and is used for fixing the position of the second threaded rod 31 on the first threaded rod 21. The inner cavity of the second threaded rod 31 matches the threaded Kirschner wire 50 to guide the direction of the threaded Kirschner wire 50.
[0035] Specifically, by radially opening the second threaded hole on the first threaded rod 21 and introducing the longitudinal pressure threaded guide structure 30, the accurate guidance of the threaded Kirschner wire 50 is realized. The second threaded rod 31 is a hollow tube, which cooperates with the second threaded hole, penetrates the first threaded rod 21 through the second threaded hole and is perpendicular to the first threaded rod 21, the inner cavity of the second threaded rod 31 cooperates with the threaded Kirschner wire 50, and the stability and accuracy of the threaded Kirschner wire 50 during the operation are ensured. At the same time, the second nut 32 is threaded on the outside of the second threaded rod 31, which effectively fixes the position of the second threaded rod 31 on the first threaded rod 21, further enhances the stability and reliability of the whole structure, and improves the flexibility and convenience of the operation, so that the operator can more easily control the movement and drilling position of the threaded Kirschner wire 50.
[0036] In a possible implementation, the structure of the second nut 32 is the same as that of the first nut 22.
[0037] Specifically, the first end outer surface of the second nut 32 is also threaded, which facilitates tightening the nut with the help of a tool, so that the operator can easily and efficiently tighten the nut, further improving the work efficiency.
[0038] The application is further illustrated by the following process:
[0039] After the coracoid process is exposed through the small incision on the front side of the clavicle, the acromioclavicular joint dislocation reduction and compression wire passer is prevented from dislocating along the medial and lateral sides of the coracoid process, and the apposition of the second end opening of the wire passing structure 10 is adjusted through the two first nuts 22 and the first threaded rod 21, and the lead wire 60 is introduced through the opening end of one short column 12 and led out from the opening end of another short column 12. The second end of the second threaded rod 31 is pressed against the appropriate site above the clavicle, and the second nut 32 is locked, completing the reduction and compression of the clavicle. Then the threaded Kirschner wire 50 is placed into the second threaded rod 31 from the first end of the second threaded rod 31, and the tip of the threaded Kirschner wire 50 is drilled into the site of the pressed clavicle from the second end of the second threaded rod 31. Then the acromioclavicular joint dislocation reduction and compression wire passer is removed, and the threaded Kirschner wire 50 is drilled through the clavicle to the coracoid process, maintaining the reduction effect, and the threaded Kirschner wire 50 is left in place, and the high-strength wire or graft is introduced through the lead wire 60 that has been passed around the coracoid process.
[0040] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
