RATCHETING INSERTER DEVICE AND SUTURE ANCHOR ARRANGEMENT

摘要

A ratcheting inserter device for tensioning a knotless suture anchor includes an outer inserter shaft and an inner inserter shaft having a common longitudinal axis. A ratcheting mechanism provided between the inner inserter shaft and the outer inserter permits rotation of the inner inserter shaft in one direction relative to the outer inserter shaft. The outer inserter shaft has a protrusion at a distal end that is received by an anchor outer sleeve of a suture anchor to prevent relative rotation thereof, and the inner inserter shaft has a projection at the distal end that is received by an inner core of the anchor for rotational movement therewith. The ratcheting inserter device rotates the inner core of the suture anchor to spool and tension suture thread. Thereafter, the ratcheting mechanism is disengaged and the inner inserter shaft is forced axially into the anchor outer sleeve.

1. A ratcheting inserter device, comprising:
a hollow outer inserter shaft having a distal end and a proximal end, including an outer shaft handle disposed at the proximal end and a protrusion projecting from the outer shaft distal end; an inner inserter shaft having a distal end and a proximal end, including an inner shaft control at the proximal end and a projection at the inner shaft distal end; and a ratcheting mechanism permitting rotation of the inner inserter shaft in one direction relative to the outer inserter shaft and preventing rotation of the inner inserter shaft in the opposing direction relative to the outer inserter shaft, wherein at least a portion of the inner shaft is positioned within the outer inserter shaft and the inner inserter shaft is rotatable relative to the outer inserter shaft in the one direction.
