Abstract
The utility model discloses a fixer for re-establishing muscle tendon/ligament attachment points. The fixer comprises a nail body and a head of the nail, wherein, the nail body and the head of the nail are connected; the front part of the nail body adopts coarse-screw threads, and the back part thereof adopts fine screw threads; the nail head adopts a hollow circular outer edge in which a suture line is wound; a front notch and a back notch are formed on the hollow circular outer edge; the suture line is led out through the front incision; and atraumatic suture needles are arranged at two ends of the suture line. The utility model has the advantages of simple structure and convenient use; as the re-establishing fixer separates a fixed part and a suture part, the suture operation is convenient, the tension of tendon or ligament can be maintained, the selection of fixation points is convenient, the fixation operation of a bolt is simple, the strength is high, and the repeated operations are feasible.
Description
Technical field
This utility model relates to technical field of medical instruments, and particularly a kind of Orthopeadic Surgery is rebuild holder with tendon ligament attachment point.
Background technology
Periarticular ligament and tendon injury very clinically more sees that majority is tearing of ligament and tendon attachment point, if malpractice causes arthrochalasis, dislocation and chronic pain easily, and then influences function of joint.Therefore, most important to the reparation of ligament and tendon, recover ligament and tendon tension force, keep the balance of power in joint, be the importance of rebuilding function of joint.
It is a clinical difficult problem that bone and tendon or interligamentous stability are rebuild always, traditional fixing means has: 1. the direct sewing of silk thread: with silk thread directly with tendon or ligament and periosteum and surrounding tissue sutured, by cicatrix healing restore funcitons, though sewing method is simple, but constant intensity is lower, higher fracture incidence rate is again arranged, the tension force of tendon or ligament is little simultaneously, occur postoperative joint strength imbalance easily and cause joint instability or subluxation, and then influence the identical damage of articular surface articular cartilage, finally cause osteoarthritis; 2. introduce the osseous tunnel method:, tendon or ligament are introduced sutured behind the opisthotonos by getting through osseous tunnel near the attachment point.There is this method of bone ridge person still can operate for around the joint, for more flat surface of bone, the operation easier of osseous tunnel is bigger, and the possibility of bone splitting is arranged, though this method can access stronger stability, but need ligament and tendon transplantation could guarantee length more, increase wound, simultaneously, when the operation by osseous tunnel, ligament and tendon have been had certain damage, the postoperative osseous tunnel can produce cutting to ligament and tendon, and the possibility of fracture is arranged.3. screw is clamp-oned method: it is bigger to introduce ligament and tendon difficulty, and this outside nut has strand to roll and dissection to it, and fracture more easily takes place postoperative.4. screw adds steel wire or tuft method: screw is a rivet, and with being fixed in the screw afterbody behind steel wire or silk suture ligament and the tendon, steel wire has tangible dissection to ligament and tendon, and the intensity of silk thread is little, is fixed in the screw afterbody and can be cut and ruptures.
Summary of the invention
The purpose of this utility model provides a kind of tendon ligament attachment point and rebuilds holder, and this holder is fixed, wound is little, easy to operate.
The technical solution of the utility model is achieved in that
This utility model comprises the nail body and the head of a nail, the nail body is connected with the head of a nail, nail body front portion is divided into coarse-pitch thread, nail body rear portion is a fine thread, the head of a nail is the outer rim of hollow circular, twines stitching thread in the outer rim of hollow circular, breach and back breach before having on the outer rim of hollow circular, preceding breach is drawn stitching thread, and there is the noinvasive sewing needle at stitching thread two.
Described nail body is plain edition or self-taped type.
Between the nail body and the head of a nail, also has pad.
This utility model is simple in structure, easy to use, because this reconstruction holder separates standing part and sutured portion, is convenient to sew application, keep tendon or tough belt tension, the convenient fixing point of selecting, the screw fixing operation is simple, and the intensity height can repeatable operation, the combination of pad and screw has good stable fixedly the time, and the design of the characteristic of pad is avoided sutural cutting and the possibility that ruptures.Utilize the noinvasive sewing needle can guarantee the relative integrity of tendon or ligament, the coupling fully of the pad and the screw head of a nail and the circular design of pad outer rim have reduced the cutting damage to surrounding tissue, therefore have fixed, simple to operate, wound is little, has improved curative effect.
Description of drawings
Fig. 1 is the structural representation of nail body of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is a head of a nail structural representation of the present utility model.
Below in conjunction with accompanying drawing content of the present invention is described in further detail.
The specific embodiment
Shown in Fig. 1,2,3, nail body of the present utility model 1 the place ahead major part is a coarse-pitch thread, can be plain edition or self-taped type, the rear portion of nail body is a fine thread, the head of a nail 2 is thick sloping type structure in outer the approaching, the head of a nail 2 afterbody central authorities are interior hexagonal configuration, and the interior hexagonal spiral shell cutter of available coupling screws or unclamp operation.The pad outer rim is a hollow circular, walked in it slidably that nylon wire maybe can absorb the polyglycolic acid stitching thread, the two ends of line all have atraumatic suture needle 6, and the semi-ring breach is arranged before and after the outer rim of hollow circular, the place ahead breach 4 is sutural outlet, and rear breach 5 can suitably be adjusted stitching thread; The pad inwall is provided with female thread, this female thread and nail body 1 rear fine thread coupling; The outer rim of hollow circular has the high outside and low outside gradient, is complementary with the head of a nail 2.Lock screw is screwed in the pad, promptly becomes this utility model tendon ligament attachment point and rebuild holder.
This utility model is made up of lock screw and pad, lock screw nail body long 25mm, external diameter 3.5mm, pad internal diameter 3.5mm and its coupling.Pad external diameter 12.0mm, thick 6.0mm, the hollow outer rim internal diameter 0.5mm on the pad.
During operation, sew up tendon or ligament from the broken ends of fractured bone to body " 8 " word or the braiding of tendon or ligament with the stitching thread on the head of a nail 2 earlier, it is firm to tie a knot, tractive tendon or ligament, keep certain tension force, the position of locating shim mesopore and bone will be followed closely body and be worn spacers in this position, promptly reach to rebuild fixedly purpose.
