Fenestrated locking suture anchor assembly

摘要

The technology includes an anchor assembly for tissue repair having an open helical coil sleeve and a tip structure. The tip structure includes an aperture for passing a suture and a suture capture member for capturing a suture. The technology also includes an anchor driver for installing an anchor into bone. The anchor driver includes an outer shaft and a sleeve advancement member for advancing the sleeve as well as an inner shaft and a suture capture advancement member for advancing the suture capture member. The technology also includes a system for tissue repair having an anchor assembly and an anchor driver for installing the anchor assembly into bone.

主权项

1. An anchor driver comprising:
a grooved outer shaft engageable with a sleeve; an inner shaft engageable with a suture capture member of a tip structure; and a handle assembly comprising:
a suture capture advancement member operatively coupled to the inner shaft, wherein the suture capture advancement member advances the suture capture member into a distal, suture-locked position;a sleeve advancement member operatively coupled to the grooved outer shaft wherein the sleeve advancement member advances the sleeve into engagement with the tip structure;a handle grip located between the suture capture advancement member and the sleeve advancement member; andan axially compliant member configured to allow a relative motion between the grooved outer shaft and the inner shaft along a longitudinal axis of the anchor driver;wherein, the suture capture advancement member further comprises a torque limiter for limiting a maximum torque applicable to the inner shaft, the torque limiter providing audible feedback to a user.
