ABSTRACT:
A tool for laparoscopic surgery comprising an elongated handle, an actuator connected to the handle between the opposite ends, a bore extending therethrough, a tool rod positioned in the bore, an actuator connected to the handle and engaging the tool rod for reciprocal motion within the bore. A sleeve extends over the tool rod and is secured to the handle. An instrument is secured to the tool rod at its distal end and is actuable by the sliding motion of the tool rod within the handle and sleeve. The handle has a cylindrical external surface and a grip remote from the distal end of the handle such that the handle can be held in the surgeon's hand like a writing instrument and the actuator be manipulated by the forefinger of the hand holding the tool to operate the instrument equally conveniently by right handed and left handed surgeons.
