16. A manually powered surgical instrument for placing a self-tapping bone screw and an associated suture on the posterior portion of a pubic bone during a surgical procedure for treating incontinence, the instrument comprising:
-
a handle, a manually movable lever having an end, the end of the lever being movable relative to the handle between a release position with the end of the lever spaced from the handle and a squeezed position with the end of the lever spaced closer to the handle than in the release position, a body portion, a screw mount for receiving the self-tapping screw, the screw mount being rotatable to rotate the self-tapping screw into pubic bone in a delivery rotation direction; and
a drive operatively associated with the lever to rotate the screw mount in the delivery rotation direction both when the lever moves from the release position toward the squeezed position and when the lever moves from the squeezed position toward the release position.
