    摘要: A handpowered, low cost, disposable laparoscopic surgical tool has a proximal hand engageable unit, an elongate extension unit and a distal jaw unit. Pulling a trigger of the hand engageable unit forwards an extension rod in the extension unit to pivot the jaws together. In one embodiment of the invention, the handle unit is primarily of molded plastic material for low cost and disposability. In an embodiment, electrocautery contact with the extension unit is through a bendable spring element. In an embodiment specially shaped links and connected jaw portions improve strength and control in opening and closing the jaws.
