Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a fishbone wire cutting machine. Background Art

[0002] Medical sutures refer to special medical threads used for ligation and hemostasis, suturing and tissue suture in surgical operations. They are divided into absorbable sutures and non-absorbable sutures.

[0003] Fishbone barbs are a specialized surgical suture with paired, blunt-edged, fishbone-like projections on either side. While first-generation barbs are manufactured by cutting, which compromises the suture's tensile strength, second-generation barbs utilize an embossing process that maintains this strength. These fishbone-shaped barbs provide enhanced tissue grip, effectively preventing incision dehiscence caused by excessive tension.

[0004] The production of fishbone wires requires punching or cutting of the wires. However, existing devices have low efficiency, making it difficult to achieve efficient production. They are also restricted by fixed formats and cannot change the specifications of the fishbone wires as needed, which requires improvement. Utility Model Content
