A hand-held manual surgical instrument that enables the user performing an internal suturing procedure (e.g., suturing a heart valve in the thoracic cavity) to advance suture knots created extracorporeally to the point of appropriate suture tension. It is a long, thin, rod-like device that has a guiding mechanism (e.g., an eyelet or groove) at its distal end, allowing it to be steered down one end of the suture as it pushes the knot with its blunted nose. Saline may be used to lubricate the suture and the knot pusher if necessary. This is a reusable device.
