The utility model discloses a tip can directly pierce through the tendon, and open the direct centre gripping tendons of two tips and carry out the tendon and weave and sew up, easy operation, reliable and stable, thus convenient safety is effectively pull the fracture tendon and is carried out the tendon and weave and sew up the operation.

Description

A kind of traction apparatus sewed up for tendon braiding

Art

This utility model relates to area of medical devices, especially relates to a kind of traction apparatus sewed up for tendon braiding.

Background technology

Tendon is the vital tissue structure connecting osteoarthrosis with muscle, if osteoarthrosis ratio does the steelframe of crane, tendon is the rope pulling weight, and the nerve arranging muscle is then circuit.Even osteoarthrosis and muscle function are in normal condition after Tendon Defection or fracture, joint also can only carry out passive activity, can not complete active movement.Tendon injury or the treatment of Tendon Defection and due to after nerve injury reconstruction be the most all that of hands surgical field is important and the problem of complexity, braiding stitching is that in hands surgical field, Tendon Defection is transplanted and reconstruction tendon repair in late period is most common method, also being one of most reliable method, the quality of tendon repair quality and therapeutic effect have vital effect.

Previously commonly using sharp knife sheet when tendon braiding is sewed up and tendon pierces through an osculum, then passed from aperture by mosquito clamp, after transplanting tendon or braiding tendon are pulled out from tendon hole, braiding is sewed up.The shortcoming of the method: 1. tendon is easily completely cut off by sharp knife, is also not easy to grasp the size of cut hole；During the most braidings, program bothers, it is also desirable to assistant coordinates, and easily hurts assistant.3. tendon is caused damage by mosquito formula blood vessel far-end pincers teeth groove.

Summary of the invention

It is an object of the invention to be to provide a kind of simple to operate, easy to use, safely and effectively traction fracture tendon carries out the traction apparatus that tendon braiding is sewed up.

In order to achieve the above object, the technical scheme of this utility model following structure of employing: a kind of traction apparatus sewed up for tendon braiding, it is made up of first-hand depression bar and second-hand's depression bar, being characterized in: have the semicircle connecting plate of evagination in the middle part of first-hand depression bar, top is the long body of rod of arc, and body of rod arc side has longitudinal groove, constitute triangular groove body of rod cross section, its top is tapered for tip, and tip medial surface is carved with anti-slip veins, and bottom connects circular hole handle ring；Second-hand's depression bar is identical with first-hand pressure rod structure, by two corresponding superpositions of semicircle connecting plate in the middle part of first-hand depression bar and second-hand's depression bar, it is fixedly connected as dynamic hinge rotating mechanism by rivet, the triangular groove body of rod of second-hand's depression bar embeds in first-hand depression bar triangular groove, two tips tightly engage, two circular hole handle rings have spacing parallel relatively, thus constitute the traction apparatus sewed up for tendon braiding.

During this utility model operation, its tip can be directed through tendon, utilizes compressing two to hold ring and opens two tips, directly clamping tendon carries out tendon braiding stitching, avoiding secondary and change the tedious steps of apparatus, its die contact area amasss little, degree of injury to tendon when pinching.

This utility model is simple to operate, reliable and stable, can easily safely and effectively draw fracture tendon thus carry out tendon braiding suture operation, reach purpose.
