First Claim
1. A surgical instrument comprising:
- an elongate shaft;
a working end platform formed on a distal end portion of said elongate shaft;
a handle mounted on a proximal end portion of said elongate shaft;
a stitching needle rotatably mounted relative to said platform and rotatable from a concealed position in which a tip of said stitching needle is concealed within said platform to an exit position where said tip is inserted into a suture anchor releasably attached to said platform, and counter-rotatable from said position where said tip is inserted into said suture anchor to said position in which said tip is concealed within said platform; and
a stabilizing pin movably mounted to said platform, said stabilizing pin being actuatable from a recessed position in which a tip of said stabilizing pin is concealed within said platform to a stabilizing position where said tip extends out of said platform, and vice versa.

10. A surgical instrument comprising:
-
an elongate shaft; a stitching needle rotatably mounted relative to said elongate shaft and rotatable from a concealed position in which a tip of said stitching needle is concealed within said platform to an exit position where said tip is inserted into a suture anchor releasably attached to said platform, and counter-rotatable from said position where said tip is inserted into said suture anchor to said position in which said tip is concealed within said platform; and a suture releasably mounted on said stitching needle, said suture including a catch member fixed to a distal end portion of said suture, wherein said stitching needle delivers said suture to said suture anchor when driven from said concealed position to said exit position, and wherein said catch member is retained by said suture anchor, preventing said suture from returning to said concealed position when said stitching needle counter-rotates to said concealed position. - View Dependent Claims (11, 12)

13. An assembly for surgical treatment of a patient, said assembly comprising:
-
a stitching instrument comprising; a first elongate shaft; a stitching needle rotatably mounted relative to said elongate shaft and rotatable from a concealed position in which a tip of said stitching needle is concealed within said platform to an exit position where said tip is inserted into a suture anchor releasably attached to said platform, and counter-rotatable from said position where said lip is inserted into said suture anchor to said position in which said tip is concealed within said platform; a suture releasably mounted on said stitching needle, said suture including a catch member fixed to a distal end portion of said suture, wherein said stitching needle delivers said suture to said suture anchor when driven from said concealed position to said exit position, and wherein said catch member is retained by said suture anchor, preventing said suture from returning to said concealed position when said stitching needle counter-rotates to said concealed position; and a suturing instrument connected to said stitching instrument, said suturing instrument comprising; a second elongate shaft; each said suture extending proximally from each said suturing needle, respectively, thorough said second elongated shaft and proximally of said second elongated shaft; and a cutting mechanism configured to cut each said suture at a location of a distal end portion of said second elongate shaft, proximal of said suturing needle, respectively. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
