AI Technical Summary

Technical Problem

In existing technologies, the suture perforations of the sealing membrane are irregular, easily deformed, and unstable, which leads to instability of the sealing disc during the closing and release process. The sutures are easily pulled out with large through holes, affecting the sealing effect, and the connection position between the sutures and the sealing membrane is difficult to control precisely.

Method used

Through holes are set on the sealing membrane at circumferential intervals. The radial length of the through holes is less than the circumferential length along the substrate. The edges of the through holes are reinforced. The sutures are sewn into the support mesh through the through holes. The shape of the through holes is elliptical or other regular shape. The ablation structure is formed by laser processing to enhance stability.

Benefits of technology

It achieves a uniform tensile force distribution between the suture and the sealing membrane, avoiding deformation or breakage of the through-hole, ensuring the stability and sealing effect of the sealing membrane, avoiding suture connection misalignment and fraying, and improving the stability of the sealing disc's closure and release.

Abstract

The application relates to the technical field of medical devices, in particular to a sealing membrane, a sealing disc and a sealing device. The sealing membrane comprises a disc-shaped base body and a plurality of through holes which are arranged on the base body in a circumferential direction at intervals, the length of the through holes in the radial direction of the base body is smaller than the length of the through holes in the circumferential direction of the base body, and the edges of the through holes are reinforcing structures. In the application, the connecting position of the suture and the base body can be accurately controlled, and the technical problem that the connecting position between the suture and the sealing membrane is unevenly distributed is avoided; by arranging the through holes in the radial direction of the base body, the length of the through holes in the radial direction of the base body is smaller than the length of the through holes in the circumferential direction of the base body, and the edges of the through holes are reinforcing structures, the moving space of the suture in the radial direction of the membrane is small, the suture is prevented from being excessively pulled, the pulling force between the suture and the sealing membrane is evenly distributed in the process of folding and releasing of the sealing disc, the suture is not prone to pulling the sealing membrane, the phenomenon that the position of the through hole is deformed or broken is avoided, and the quality of the sealing membrane is ensured.
