Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a medical tissue suture clamp. Background Technology

[0002] During orthopedic surgery, surgical instruments are used to clamp and fix the ligaments at the injured site. Then, a suture mechanism on the surgical instruments, with its telescopic movement, threads and sutures the ligaments. For example, publication CN219147719U discloses a suture device for reconstructing anterior cruciate ligaments with residual ligament retention. The needle is positioned at the top between two arc-shaped metal clips. When threading the suture through the needle, the arc-shaped metal clips can both cooperate with a movable plate to clamp the ligament remnant to facilitate needle puncture, and also clamp the suture end after threading to bring it back.

[0003] However, ligaments are strong, and the flat suture mechanism in existing surgical instruments is difficult to puncture ligaments, resulting in technical problems such as difficult ligament suturing and long operation time. Utility Model Content
