Combined tool for suture hook in sports medicine rotator cuff injury operation

Abstract

The invention discloses a combined tool for a suture hook in a sports medicine rotator cuff injury operation. The combined tool comprises a first bending tool and a second bending tool. The first bending tool comprises a fixing device, a primary bending operation assembly, a secondary bending fixing assembly and a secondary bending operation sleeve, wherein the primary bending operation assembly is operated by a user to conduct bending, and the secondary bending operation sleeve is operated by the user to conduct bending. The primary bending operation assembly is rotatably mounted on the fixing device; the secondary bending fixing assembly is detachably installed on the fixing device; and the second bending tool comprises a base, an inner locking sleeve, an outer locking sleeve, a positioning and clamping block, a movable clamping block, a rotating pin, a positioning block used for being installed on the positioning and clamping block to make contact with the base so as to limit the position of the positioning and clamping block, and a detachable stop block used for abutting against the sharp corner of a sewing hook blank so as to position the sewing hook blank. The combined tool has the beneficial effects that the bending efficiency is high, the stability is high, and the consistency of sharp corners of cutting edges is good.

Description

technical field [0001] The invention relates to a combination tool for suturing hooks in sports medicine rotator cuff injury operation. Background technique [0002] With the development of sports medicine, surgical treatment of rotator cuff tear has been paid more and more attention and application. There are many methods of surgical treatment. For third-degree partial tears and full-thickness tears with tear openings less than 5cm, anchors with sutures are used for suturing. The shape and angle of the thread-passing suture hook are changeable, and it needs to be bent in multiple places. [0003] At present, there are three main bending methods for thread suture hooks: [0004] The first method: use forming mold to bend; [0005] The second type: use a special CNC pipe bending machine to bend; [0006] The third method: use manual bending. [0007] At present, there are two main processing methods for the cutting edge and sharp corner of the suture hook: [0008] The ...

Problems solved by technology

[0010] Using forming molds for bending, the bending shape of this method is fixed and immutable, and the mold needs to be changed again if the angle or radius is changed. Machine bending, the quality of products processed by this method is stable, but the equipment is expensive, and the operator's skill requirements are also high; using manual bending, the processing quality of this method is unstable and inefficient

[0011] After all the bending is completed, the cutting edges and sharp corners are thrown out manually on the grinding wheel. This method requires high skills of the operator, otherwise it is difficult to ensure the consistency of the cutting edges and sharp corners; after all the bending is completed, use mechanical processing methods, such as milling / grinding cutting edges and sharp corners, because the bending is multiple bends that can not be folded in one plane, the cumulative error is large, the tooling design is difficult, and the consistency of the sharp corners of the cutting edges is relatively low. Difficult to control
