Abstract

A combined knot pusher/suture cutter device for manipulating a knotted suture to properly locate the knot relative to the tissue being sutured, and then for removing excess suture from the knot. The knot pusher/suture cutter includes a body member with a handle and an inner member (or inner rod) having a knot-engageable section at the opposite end (distal end) for engaging and moving the knotted suture by manipulation of the handle. The knot-engageable section of the inner member is provided with a slot at its distal end which allows suture to be threaded through it. The inner member is provided within an outer sleeve that is designed to be actuated by a spring and a thumb pusher (trigger) located on a surface of the handle. By actuating the thumb trigger (for example, by sliding forward the thumb trigger), the outer sleeve is advanced and the suture post is cut.
