Description

Technical Field

[0001] The utility model relates to the technical field related to medical devices, in particular to a thread-free suture needle. Background Art

[0002] Medical suture needles are mainly used for surgical sutures. They are mostly made of stainless steel wire with holes or grooves drilled at the needle tail. The surface is polished and electrolytically treated and should be very smooth. The needle type is divided into round needles, angle needles, shovel needles, straight needles, etc. according to actual needs. The curvature is divided into 1 / 2, 3 / 8, etc. according to actual needs. The production process is very complicated and it is a high-tech product. Fine drilling even uses laser drilling technology.

[0003] The existing suture needle has the following shortcomings when in use: medical staff are required to clamp the suture needle and then insert the end of the suture thread through the thread hole of the suture needle. Since the thread hole is small, threading is inconvenient, which affects work efficiency. Utility Model Content

[0004] The purpose of the present invention is to provide a thread-free suture needle to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a thread-free suture needle, comprising a main body and a thread-free mechanism connected to the main body, the main body as a whole being composed of a needle head, a needle body, and a needle tail fixedly connected in sequence, the needle tail being U-shaped as a whole, and the opening being at one end of the principle needle body, the thread-free mechanism being composed of two first fixing blocks and an anti-falling mechanism, the two first fixing blocks being respectively arranged at the ends of the needle tail, the two first fixing blocks and the needle tail together forming a thread hole, and the anti-falling mechanism being arranged on the inner wall of the thread hole.

[0006] Preferably, the anti-falling mechanism is composed of two second fixing blocks, the two second fixing blocks are respectively arranged on the inner sides of the two first fixing blocks, and the inner sides of the lower ends of the two second fixing blocks abut against each other.

[0007] Preferably, a gap communicating with the wire hole is formed between the two first fixing blocks and between the two second fixing blocks.

[0008] Preferably, an arc-shaped groove is provided at the upper end of the gap.

[0009] Preferably, the main body, the thread-free mechanism and the anti-falling mechanism are all made of stainless steel.

[0010] Preferably, the first fixing block, the second fixing block and the needle tail are all integrally formed.

[0011] Compared with the prior art, the beneficial effect of the present invention is that two first fixing blocks are arranged at both ends of the needle tail, and a second fixing block is arranged on the inner side of the first fixing block, and gaps connected to the thread hole are formed between the two first fixing blocks and the two second fixing blocks. When in use, the suture thread is held in the hand so that it spans the arc-shaped groove, and then the suture thread is pulled downward so that the suture thread passes through the gap and enters the thread hole, thereby completing the connection between the suture thread and the main body. At the same time, since the lower ends of the two second fixing blocks abut against each other, the suture thread can be effectively prevented from falling off. The overall structure is simple, and the operation is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-2 The utility model provides a technical solution: a thread-free suture needle, comprising a main body and a thread-free mechanism connected to the main body, wherein the main body as a whole is composed of a needle head 1, a needle body 2, and a needle tail 3 fixedly connected in sequence, the needle tail 3 is U-shaped as a whole, and the opening is at one end of the principle needle body 2, the thread-free mechanism is composed of two first fixing blocks 4 and an anti-falling mechanism, the two first fixing blocks 4 are respectively arranged at the ends of the needle tail 3, the two first fixing blocks 4 and the needle tail 3 together constitute a thread hole 5, and the anti-falling mechanism is arranged on the inner wall of the thread hole 5.

[0017] The anti-falling mechanism is composed of two second fixing blocks 6 , which are respectively arranged on the inner sides of the two first fixing blocks 4 , and the inner sides of the lower ends of the two second fixing blocks 6 abut against each other.

[0018] A gap 7 communicating with the wire hole 5 is formed between the two first fixing blocks 4 and between the two second fixing blocks 6 .
