Description

Stitch clamping structure and medical suture wire reel Technical Field The utility model relates to the field of medical instrument packaging, in particular to a stitch clamping structure and a medical suture wire spool. Background Medical suture is a common biological textile used for suturing human body operation, is used for suturing wounds, connecting tissues, ligating blood vessels and the like, and consists of a suture needle made of hard materials and a suture made of flexible materials. Medical sutures are usually stored in sterile bags, opened at the operation site and taken out for use, but after long-term storage in sterile bags, the suture is easy to bend and tie, cannot be taken out smoothly and the barb structure on the suture may be damaged. Currently, the package of medical suture mainly comprises two types, namely a paper winding plate and a plastic winding tray. Most of paper winding plates adopt an 8-shaped winding method, the suture is fixed on the paperboard after being wound in an 8 shape, the suture needle and the suture are packaged by the paperboard in a layered mode, the suture is pulled out when the suture is taken out, the suture can be straightened conveniently before operation, but the suture is easy to produce adverse effects when the suture is extruded by external force due to the fact that the paperboard is soft. Most of plastic winding trays adopt an O-shaped winding method, which mainly winds suture in the plastic tray and fixes the suture needle on the tray, and the plastic tray has better strength, so that the suture can be protected when being extruded by external force. Chinese patent publication No. CN201389047Y discloses a "medical suture packaging box", which has a hard tray type box body composed of an upper shell and a lower shell, wherein the upper shell is internally provided with a discontinuous arc-shaped inner edge bead and outer edge bead, the upper shell and the lower shell are buckled, a 8-shaped slot is formed between the inner edge bead and the outer edge bead, and a plurality of suture mounting positioning holes are respectively arranged on the upper shell and the lower shell along the 8-shaped slot. The medical suture packaging box combines the advantages of the paper winding plate and the plastic winding tray, so that the suture can be pulled out smoothly and is not easy to tie. Chinese patent publication No. CN205094527U discloses an inner package capable of containing a plurality of medical suture needles with threads, wherein the package material is made of medical polypropylene material, each suture thread is orderly fixed around an inner frame in a surrounding manner, a plurality of pressure caps are arranged on the periphery, so that the suture thread cannot deviate from the inner frame, each suture needle is provided with a specific bayonet, and the ordered arrangement of the suture thread and the suture needle is ensured. The inner package of the suture needle with the thread adopts a multi-piece design, and the suture needle and the suture thread can be extracted for multiple times in the operation process, so that the problem of operation delay is avoided to a certain extent. Similar prior art is that the package for suture and needle disclosed in Chinese patent publication No. CN 109928086A, the medical suture needle wire spool disclosed in Chinese patent publication No. CN215534693U, and the like, which all adopt a hard winding tray structure to realize the winding of suture and the fixation of suture needle. However, in the prior art, the two modes of sponge and clamping columns are generally adopted for fixing the suture needle, the suture needle is inserted into the sponge for fixing, but the taking operation of the suture needle is relatively complicated, and the three or four clamping columns are utilized for clamping and fixing the suture needle. Disclosure of Invention 1. Technical problem to be solved by the utility model The utility model aims to overcome the defects in the prior art and provide a needle clamping structure and a medical suture wire spool, by adopting the technical scheme of the utility model, the needle clamping structure adopts a three-column design to realize orderly clamping and fixing of arc needles, and the lower part of the corresponding clamping column is provided with a hollow cavity, so that the lower part of the clamping column is provided with a space which elastically deforms towards the opposite side of the clamping groove, the needles can be elastically clamped, and the clamping column is extruded and deformed by the needles to form the clamping groove with small upper part and big lower part, thereby not only improving the clamping firmness of the needles, but also avoiding the problem that the needles are ejected and fall off; in addition, the medical suture wire reel adopts a runway type winding groove design, has simple structure and convenient production process, can greatly reduce the damage to
