Ratcheting inserter device and suture anchor arrangement
First Claim
1. A method for securing a suture anchor into a bone comprising:
- providing a suture anchor comprising an anchor inner core and an anchor outer sleeve having an open bore hole at a proximal end for receiving and enclosing a first portion of the anchor inner core;
driving the suture anchor into bone with an inserter device to dispose the proximal end of the anchor outer sleeve adjacent a bone surface;
tensioning suture threads coacting with the suture anchor by moving an inner inserter shaft of the inserter device in a first direction to rotate the anchor inner core relative to the anchor outer sleeve; and
securing the anchor inner core to the anchor outer sleeve by moving the inner inserter shaft in a second direction different from the first direction.

Abstract
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 shaft 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.

27. A method for securing a suture anchor into a bone comprising:
-
providing a suture anchor comprising an anchor inner core and an anchor outer sleeve having an open bore hole at a proximal end for receiving and enclosing a first portion of the anchor inner core with a second portion of the anchor inner core extending away from the proximal end of the anchor outer sleeve; driving the suture anchor into bone with an inserter device to dispose the proximal end of the anchor outer sleeve adjacent a bone surface; and tensioning suture threads coacting with the suture anchor; driving the anchor inner core into the anchor outer sleeve; wherein the inserter device comprises; a hollow outer inserter shaft having an outer shaft distal end and an outer shaft proximal end; a protrusion projecting from the outer shaft distal end of the outer inserter shaft; a handle having a handle distal end and a handle proximal end, the handle distal end being connected to the outer shaft proximal end of the outer inserter shaft, with the outer inserter shaft extending from the handle; an inner inserter shaft having an inner shaft distal end and an inner shaft proximal end, the inner inserter shaft extending at least partially through the outer inserter shaft and the handle; an inner shaft control connected to the inner shaft proximal end of the inner inserter shaft at the handle proximal end; a projection projecting from the inner shaft distal end of the inner inserter shaft; 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 an opposing direction relative to the outer inserter shaft; wherein the inner inserter shaft is rotatable relative to the outer inserter shaft in the one direction; wherein movement of the inner inserter shaft relative to the outer inserter shaft drives the anchor inner core of the suture anchor into the anchor outer sleeve of the suture anchor; and wherein the anchor outer sleeve defines a bore therein which opens proximally through an outer sleeve proximal end of the anchor outer sleeve and in which the anchor inner core is disposed. - View Dependent Claims (28, 29, 30, 31, 32, 33)
