ABSTRACT:
A needle manipulator (2), particularly suited for endoscopic use, has an elongate body (4) including a base (6) and an elongate tip carrier tube (8) rotatably mounted to the base. A removable tip assembly (10), mounted at the distal end of the tip carrier tube, includes jaws (26,28) actuated by finger and thumb loops (16,18) mounted to the base. A rotary actuator trigger (78) is slidably mounted to the base. The tip carrier tube has a spiral groove (90) engaged by a cam pin (82) extending from the trigger so that axial movement of the trigger causes rotary motion of the tip carrier tube and the tip assembly therewith. Suture material (93) is supplied through the carrier tube and to a needle (118) held by the jaws.
