Arthroscopic suture passing instrument
First Claim
1. An instrument for arthroscopic suture passing, the instrument comprising:
- a shaft having a proximal end and a distal end;
a jaw disposed distally on the shaft and having a needle and a hook;
a handle disposed proximally on the shaft for manipulating the jaw; and
a movable suture shuttle disposed on the distal end of the shaft.

Abstract
An instrument for arthroscopic suture passing having a shaft with a proximal end and a distal end. A jaw disposed on the distal end has a needle and a hook. The jaw opens and closes with respect to a stationary distal tip of the instrument. A handle disposed on the proximal end manipulates the jaw. A movable suture shuttle is disposed in the distal tip of the instrument. Arthroscopic suture passing takes place by initially loading a length of suture into the suture shuttle, and capturing the suture by moving the suture shuttle away from a position in which it would engage the needle and hook. The needle then is advanced through tissue using the handle to close the jaw against the stationery tip. The suture shuttle then is advanced to load the suture onto the hook. Opening the jaw draws the needle back through the tissue, pulling the suture in a loop through the tissue. A spring arm urges tissue off of the needle. The loop of suture then is available for further suturing or knot tying.

10. A method of arthroscopic suture passing using an instrument having:
-
a shaft having a proximal end and a distal end;
a jaw disposed on the distal end and having a needle and a hook;
a handle disposed on the proximal end for manipulating the jaw; and
a movable suture shuttle disposed in the tip of the shaft, the method comprising the steps of;
loading a length of suture into the suture shuttle;
moving the suture with the suture shuttle away from a position of engagement with the needle and hook;
moving the distal end of the instrument toward tissue to be repaired;
advancing the needle through tissue by closing the jaw;
moving the suture shuttle so as to load the suture onto the hook; and
opening the jaw and removing the needle from the tissue, thereby pulling the suture through the tissue. - View Dependent Claims (11)

12. An instrument for arthroscopic suture passing, the instrument comprising:
-
a shaft;
a jaw supported on the shaft and having a needle with a hook;
a handle operatively engaged to manipulate the jaw; and
a shuttle arranged and configured to move a suture strand alternately between a position of engagement and a position of disengagement with the hook. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
