Abstract
The invention described herein is a device for tying knots intracorporeally during laparoscopic surgery. It is intended to simplify the process of tying intracorporeal knots to the point that the average laparoscopist can quickly learn to suture laparoscopically with confidence. The unique features of this invention include: a driven shuttle; integral grasper; the system is reloadable; and the system may have a detachable end effector. The system also may have a multi function handle.

7. A surgical suturing device comprising:
-
a rotatable shuttle having containment means to maintain a plurality of strands of suture like material in opposition; means to insert said suture like material to said shuttle when said shuttle is maintained by the containment means of the shuttle; a shaft comprising a drive mechanism connected to said shuttle to transfer motion from the user along said shaft to said shuttle, causing said shuttle to rotate; alignment means on said shuttle for positioning said shuttle into alignment with said drive mechanism; and a handle connected to said shaft for assembly providing a means to actuate said drive mechanism. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
