Combined Tooling for Suture Hooks in Sports Medicine Rotator Cuff Injury Surgery

Abstract

The invention discloses a combined tooling for suturing hooks in rotator cuff injury surgery in sports medicine, which includes: a first bending tool and a second bending tool; the first bending tool includes: a fixing device, which is operated by a user to perform A primary bend operating assembly for bending, a secondary bend securing assembly, and a secondary bending operating sleeve operated by the user to perform the bending; the primary bending operating assembly is rotatably mounted to the fixture; the secondary bending securing The components are detachable and installed to the fixture; the second bending tooling includes: base, inner locking sleeve, outer locking sleeve, positioning clamping block, movable clamping block, rotating pin, for installation to positioning clamping block and The base is in contact with the positioning block to limit the position of the positioning clamping block, and the detachable stopper is used to withstand the sharp corner of the suture hook blank to position the suture hook blank. The invention is beneficial in that the bending efficiency is high, the stability is high, and the sharp angle of the cutting edge is consistent.

Description

Technical field [0001] The present invention relates to a combination tooling for suturing hooks in sports medicine rotator cuff injury surgery. Background [0002] With the development of sports medicine, the surgical treatment of rotator cuff tears has received more and more widespread attention and application. There are a variety of surgical treatment methods, for the third degree partial tear and the full layer tear of the tear mouth less than 5 cm, the use of thread anchor nails for suturing, in this process, limited by the micro-traumatic opening, the shape and angle of the slender tubular over-line suture hook is changeable, and it needs to be bent in multiple places. [0003] At present, there are three main bending methods for stitching hooks: [0004] The first: the use of forming mold bending; [0005] The second kind: the use of special CNC pipe fittings bending machine bending; [0006] The third: use manual bending. [0007] At present, there are two main processin...

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
