AI Technical Summary
Traditional fracture fixation methods suffer from problems such as screw breakage, bone tunnel wall rupture, iatrogenic fractures, and fixation failure. In particular, micromovement between the bone and the implant loops and cables leads to bone wear, affecting rehabilitation and exercise.
The cable with anchor loops, including a first anchor body and a second anchor body, is screwed into the clavicle and scapula respectively. The cable is wrapped around the connecting strip and passes through the through hole to form a tight interface without micro-movement. Combined with a double-layer cable pressure fastening device, it avoids bone cutting and micro-movement.
Simplify procedures, reduce trauma, lower postoperative pain, avoid early removal of internal fixation, promote recovery, reduce financial burden, and improve fixation success rate.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to orthopedic instruments, in particular to a reconstruction of interosseous ligament with anchor loop cable. BACKGROUND
[0002] In modern society, traffic, construction industry, industrial development, the whole people fitness movement is widely carried out, ankle fracture dislocation combined with tibiofibular separation and acromioclavicular joint dislocation incidence is seen from time to time, the traditional reduction and fixation exist a variety of unreasonable, can not meet the needs of rehabilitation and sports.
[0003] The traditional surgical method includes tibiofibular interosseous screw internal fixation, titanium cable, hook loop fixation of tibiofibular joint, Kirschner wire tension band fixation of acromioclavicular joint, interscapular screw fixation and locking hook plate fixation, endobutton fixation, etc. There are screw breakage, which needs to be removed early. Kirschner wire hook plate and other exists damage to acromioclavicular joint, other fixation methods are to drill bone tunnel on the bone, introduce loop steel plate fixation, which exists intraoperative or postoperative bone tunnel wall rupture, iatrogenic fracture, postoperative loop buckle or loop titanium plate cutting bone fracture, fixation and reconstruction failure, affect sports rehabilitation, etc. We found that when there is micro-motion between the bone and the loop plate and cable, the bone is easy to cut and grind, which leads to internal fixation or ligament reconstruction failure. CONTENT OF THE UTILITY MODEL
[0004] The utility model discloses a reconstruction of interosseous ligament with anchor loop cable, mainly used in the repair and reconstruction of tibiofibular separation and acromioclavicular joint dislocation.
[0005] In order to realize the above-mentioned purpose, the utility model provides the following technical scheme.
[0006] The utility model discloses a reconstruction of interosseous ligament with anchor loop cable, including first peg body and second peg body, the first peg body twists into the distal end of clavicle, the second peg body twists into scapula, the axle of second peg body forms the through -hole, the through -hole is formed with the connecting strip close to the bottom, still includes cable, the middle part of cable is around set up in connecting strip, and is worn in through -hole, and the both ends of cable are extruded in the both sides of first peg body.
[0007] Preferably, in the reconstruction of interosseous ligament with anchor loop cable, the outer side of the first peg body and the second peg body is formed with sawtooth.
[0008] Preferably, in the reconstruction of interosseous ligament with anchor loop cable, the cable is in straightened state.
[0009] Compared with the prior art, the technical scheme has the advantages of simple operation, small trauma, less interference to the tibiofibular syndesmosis, glenohumeral joint and acromioclavicular joint, avoidance of intraoperative and postoperative bone cutting and fracture, reduction of interference and stimulation to the joint, great reduction of postoperative pain, avoidance of forced removal of internal fixation in the early stage, facilitation of postoperative exercise and rehabilitation, reduction of the economic burden of patients and saving of social cost. BRIEF DESCRIPTION OF DRAWINGS
[0010] In order to more clearly illustrate the technical schemes in the embodiments or the prior art of the present application, the drawings needed to be used in the embodiments or the prior art description will be briefly introduced as follows. Obviously, the drawings described below are only some embodiments described in the present application, and other drawings can be obtained by those skilled in the art without creative labor on the basis of these drawings.
[0011] Fig. 1 Fig. 1 shows the use state diagram of the anchor loop cable for reconstructing interosseous ligament in the embodiment of the present application;
[0012] Fig. 2 Fig. 1 shows the use state diagram of the anchor loop cable for reconstructing interosseous ligament in the embodiment of the present application;
[0013] Fig. 3 Fig. 1 shows the use state diagram of the anchor loop cable for reconstructing interosseous ligament 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 fall within the scope of protection of the present application.
[0015] In combination with Figs. 1-3 As shown, the anchor loop cable 100 for reconstructing interosseous ligament comprises a first nail body 101 and a second nail body 102. The first nail body 101 is screwed into the distal end of clavicle 200, and the second nail body 102 is screwed into scapula 300. The axis of the second nail body 102 forms a through hole 103, and a connecting strip 104 is formed at the bottom of the through hole 103. The anchor loop cable 100 further comprises a cable 105. The middle part of the cable 105 is wound around the connecting strip 104 and passes through the through hole 103. The two ends of the cable 105 are extruded on the two sides of the first nail body 101. The outer sides of the first nail body 101 and the second nail body 102 are formed with sawteeth. The cable 105 is in a straightened state.
[0016] In this embodiment, the existing cable anchor (metal, PEEK, xenobiotic bone) and the newly designed double-layer cable compression fastening locking device are combined to form a cable with anchor loop for reconstruction of the interosseous ligament. The titanium plate is fixed to the surface of the clavicle (fibula), the anchor is anchored to the coracoid process (tibia), the anchor and the interosseous ligament form a tight and micro-motion-free interface, the outer column of the double-layer cable compression fastening locking device forms a tight and micro-motion-free interface with the bone, and after the cable is compressed and tensioned appropriately, the cable is fastened and locked between the inner and outer columns. The reconstruction simulates the inferior tibiofibular ligament, coracoclavicular ligament, and trapezius ligament, forming an elastic fixation that avoids the fracture of the inferior tibiofibular screw, the micro-motion and cutting of the cable with the bone, thereby reducing the probability of internal fixation failure and failure.
[0017] This cable with anchor loop for interosseous ligament reconstruction is simple to operate, minimally invasive, and has little interference with the inferior tibiofibular joint, glenohumeral joint, and acromioclavicular joint. It can avoid intraoperative and postoperative bone cutting and fracture, reduce interference and stimulation to the joint, greatly reduce postoperative pain, avoid forced removal of internal fixation in the early stage, facilitate postoperative exercise and rehabilitation, and reduce the economic burden on patients and save social costs.
