Description

Technical Field

[0001] This utility model relates to the technical field of arc needle sewing devices, specifically to the clamping end structure of a semi-automatic arc needle sewing device. Background Technology

[0002] The semi-automatic arc needle suturing device is a medical device designed to improve tissue alignment efficiency in clinical surgery. Through its mechanical structure design, the device achieves semi-automatic operation of the arc needle, thereby simplifying the complex steps of the traditional suturing process.

[0003] Specifically, a semi-automatic arc needle suture device typically includes key components such as the main body, handle mechanism, clamping arm, guide rail, and clamping end. The handle mechanism drives the clamping arm to rotate, thereby completing the needle insertion, withdrawal, and holding actions. This design not only improves suturing speed but also reduces the operational difficulty during surgery.

[0004] However, the current clamping end structure suffers from insufficient precision and clamping force stability, as well as poor flexibility, which cannot meet the needs of high-efficiency surgical suturing. Utility Model Content

On both sides of the upper left clamping head slider and the lower left clamping head slider, upper left clamping head round pins and lower left clamping head round pins are respectively connected. On both sides of the upper right clamping head slider and the lower right clamping head slider, upper right clamping head round pins and lower right clamping head round pins are respectively connected.

[0012] Furthermore, upper left clamping head and lower left clamping head are respectively provided on the right sides of the upper left clamping head round pin and the lower left clamping head round pin, and upper right clamping head and lower right clamping head are respectively provided on the left sides of the upper right clamping head round pin and the lower right clamping head round pin.

[0014] Furthermore, the upper left clamping head round pin and the lower left clamping head round pin drive the upper left clamping head and the lower left clamping head to perform an in-opposition or separation movement in the upper guide rail cavity and the lower guide rail cavity of the left clamping arm; the upper right clamping head round pin and the lower right clamping head round pin drive the upper right clamping head and the lower right clamping head to perform an in-opposition or separation movement in the upper guide rail cavity and the lower guide rail cavity of the right clamping arm.

[0015] Furthermore, the distance dimension between the top end of the left clamping arm and the axis of the left clamping arm is equal to the distance dimension between the top end of the right clamping arm and the axis of the right clamping arm; the distance dimension between the top end of the left clamping head guide post and the axis of the left clamping head guide post is equal to the distance dimension between the top end of the right clamping head guide post and the axis of the right clamping head guide post.
