AI Technical Summary
Traditional acromioclavicular joint fixation methods can damage the acromioclavicular joint, and are prone to complications such as coracoid tunnel wall rupture, iatrogenic coracoid fracture, and clavicle fracture caused by the cutting of bone by the loop or titanium plate during surgery or postoperatively, which can affect sports rehabilitation. Furthermore, internal fixation or ligament reconstruction is prone to failure.
A loop cable system with anchors and titanium plates is used. The anchors are fixed to the distal end of the clavicle, and the cables are screwed into the scapula to form a tight interface without micro-movement, simulating the coracoclavicular ligament and trapezius ligament, avoiding micro-movement and cutting phenomena, and achieving elastic fixation.
It is easy to operate, minimally invasive, reduces bone cutting and fractures during and after surgery, lowers postoperative pain, and promotes postoperative exercise and rehabilitation.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to orthopedic instruments, in particular to a hinged cable system with an anchor and a titanium plate. BACKGROUND
[0002] In modern society, with the development of transportation and industry, and the development of national fitness movement, the incidence of acromioclavicular joint dislocation has increased significantly. The traditional reduction and fixation has many unreasonable aspects and cannot meet the needs of rehabilitation and exercise.
[0003] Traditional surgical methods include Kirschner wire tension band fixation of the acromioclavicular joint, interscapular screw fixation, clavicular hook plate fixation, and endobutton fixation. Kirschner wire of the acromioclavicular joint causes damage to the acromioclavicular joint. Other fixation methods involve drilling bone tunnels on the clavicle and coracoid process, introducing a hinged plate for fixation, and causing intraoperative or postoperative rupture of the coracoid bone tunnel wall, iatrogenic coracoid fracture, postoperative cutting of bone by the hinged buckle or hinged titanium plate, leading to clavicular fracture, fixation and reconstruction failure, and affecting exercise rehabilitation. We found that when there is micro-motion between the bone and the hinged plate and cable, the bone is prone to cutting and grinding, leading to internal fixation or ligament reconstruction failure. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims at providing a hinged cable system with an anchor and a titanium plate, which is mainly used for the repair and reconstruction of acromioclavicular joint dislocation.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme.
[0006] The utility model discloses a hinged cable system with an anchor and a titanium plate, which comprises a first plate body, a first anchor is arranged on the surface of the first plate body, the first anchor is fixed to the distal end of the clavicle, thread holes are formed at the two ends of the first plate body respectively, a cable is arranged in each thread hole, the bottoms of the two cables are screwed into the scapula through screws respectively, and the cable is extruded on the outside of the screw.
[0007] Preferably, in the hinged cable system with an anchor and a titanium plate, two anchors are arranged on the left and right sides.
[0008] Preferably, in the hinged cable system with an anchor and a titanium plate, the cable is in a straightened state.
[0009] Preferably, in the hinged cable system with an anchor and a titanium plate, the cable is one, the middle part of the cable passes through the thread hole, and the two ends of the cable are screwed into the scapula through the screws respectively.
[0010] Preferably, in the hinged cable system with an anchor and a titanium plate, the length of the first plate body is greater than the width of the clavicle.
[0011] Compared with the prior art, the technical scheme has the advantages that the operation is simple, the trauma is small, the glenohumeral joint and acromioclavicular joint of the shoulder are not interfered, bone cutting and fracture during and after the operation can be avoided, the interference and stimulation to the joint are reduced, the postoperative pain is greatly reduced, and postoperative exercise and rehabilitation are facilitated. BRIEF DESCRIPTION OF DRAWINGS
[0012] In order to more clearly illustrate the technical schemes in the embodiments of the present application or the prior art, the drawings needed to be used in the embodiments or the prior art description will be briefly introduced below. Obviously, the drawings described below are only some embodiments described in the present application, and for those skilled in the art, other drawings can also be obtained without creative labor on the basis of these drawings.
[0013] Figure 1 The figure shows the schematic diagram of the halyard cable system with anchor nails and titanium plates in the embodiment of the present application. DETAILED DESCRIPTION
[0014] The technical schemes in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.
[0015] In combination with Figure 1 As shown, the halyard cable system with anchor nails and titanium plates 100 comprises a first plate body 101, the first plate body 101 is provided with a first anchor nail 102 on the surface, the first anchor nail 102 is fixed to the distal end of the clavicle 200, the two ends of the first plate body 101 are respectively formed with a threading hole 103, a cable 104 is arranged in each threading hole 103, the bottoms of the two cables 104 are respectively screwed into the scapula 300 through a screw 105, and the cable 104 is extruded on the outside of the screw 105. The anchor nails are oppositely arranged in left and right directions. The cable 104 is in a straightened state. The cable 104 is one, the middle part of which passes through the threading hole 103, and the two ends of which are screwed into the scapula 300 through the screw 105. The length of the first plate body 101 is greater than the width of the clavicle 200.
[0016] In this embodiment, the existing cable anchor nail and the newly designed hole titanium plate are combined into a halyard cable system with anchor nails and titanium plates, the titanium plate is fixed to the surface of the clavicle, the anchor nail is anchored to the coracoid process, a close and micro-motion interface is formed between the titanium plate and the clavicle, a close and micro-motion interface is also formed between the anchor nail and the coracoid process, only micro-motion and friction exist between the cable and the hole of the titanium plate, the coracoclavicular ligament and the trapezius ligament are reconstructed and simulated, and elastic fixation is formed, so as to avoid the micro-motion and cutting phenomenon between the halyard plate and the halyard cable and the bone, thereby reducing the probability of internal fixation failure and failure.
[0017] This titanium plate and anchor loop cable system is easy to operate, minimally invasive, and does not interfere with the glenohumeral and acromioclavicular joints of the shoulder. It can avoid bone cutting and fractures during and after surgery, reduce interference and stimulation to the joints, greatly reduce postoperative pain, and facilitate postoperative exercise and rehabilitation.
