AI Technical Summary

Technical Problem

The depth penetration limiter of existing tissue repair devices is prone to accidentally detaching from the device housing during use, increasing surgical time and operational difficulty, and the high friction on the connecting feature surfaces makes rapid assembly difficult.

Method used

A depth penetration limiter was designed with a built-in self-stopping feature. It is locked in the recess of the housing by a cantilevered flexure to prevent detachment, and the pull-out resistance is increased by connecting features such as circumferential ribs or barbs to simplify the assembly process.

Benefits of technology

It effectively prevents the deep penetration limiter from accidentally dislodging, reduces surgical time, improves operational efficiency, and simplifies the assembly process through improved connection features.

Abstract

用于与半月板修复装置一起使用的深度穿透限制器,所述深度穿透限制器具有内置的自止动特征以防止限制器从装置壳体脱离。自止动特征是限制器的底表面上的悬臂式挠曲部,其在移动通过壳体时挠曲。随着挠曲部通过壳体中的凹部的边缘,挠曲部返回到其原始形状,从而使挠曲部卡在凹部内,并且防止限制器 / 深度管进一步向远侧移动。限制器上的连接特征提供深度管从限制器的增大的拉出阻力。
