Problems solved by technology
However, as mentioned above, the gap between the diameter of the needle body and the diameter of the steel wire of the traditional steel wire suture needle is too large, and a large amount of bleeding often occurs during specific suturing, and this is the main shortcoming of the traditional technology.

Embodiment approach
[0054] Such as Figure 11 As shown, it is the second embodiment of the present invention. The steel wire 20 includes a connecting end 21 and a steel wire body 22. A connecting layer 30 is arranged on the steel wire body 22. The cross-sectional area size of the connecting layer 30 is the same as that of the suture needle. The ratio between the cross-sectional area dimension C of the steel wire connection end 12 and the arc transition portion 13 of 10 is 0.75:1.

The invention relates to a suture needle without an astrictive steel wire, comprising a suture needle and a steel wire. The steel wire is connected to one end of the suture needle. The suture needle comprises a skeleton penetrating end, a steel wire connecting end and an arc transition part. The steel wire is connected to the steel wire connecting end of the suture needle. The steel wire comprisesa connecting end and a steel wire body. The steel wire connecting end and the arc transition part of the suture needle have a uniform size of cross section. The ratio of the cross section size of thesteel wire body to the cross section size of the steel wire connecting end and the arc transition part of the suture needle is (0.6 to 0.8):1.
Description
technical field [0001] The invention relates to a suture needle, in particular to a steel wire suture needle which is used for suturing human bones and can reduce bleeding. Background technique [0002] As we all know, bones are hard organs that make up the endoskeleton of vertebrates, and their functions are to move, support and protect the body. The bones of the human body play a role in supporting the body and are part of the human body movement system. The bones are generally connected by joints and ligaments. Bone is mainly composed of three parts: bone, bone marrow and periosteum, and contains rich blood vessels and nerve tissues. Bone is composed of organic matter and inorganic matter. The organic matter is mainly protein, which makes the bone have a certain toughness, while the inorganic matter is mainly calcium and phosphorus, which make the bone have a certain hardness. The bones of the human body are composed of a certain proportion of organic and inorganic subs...
