Abstract
Palm-size staplers for surgical procedures are proposed. The staplers include cartridge and slider assemblies with the cartridge assembly containing staples. As the slider assembly advances step-wise incrementally it provides a staple ejection force causing ejection of staples. Optionally a blade element may be included for cutting. An anvil member is operable in closed and open positions with respect to the cartridge assembly. When in a closed position, the anvil member holds a portion of tissue against the cartridge assembly, ejected staples passing through the held tissue. Actuation of the staplers is effected by a lever member. The staplers have a selector element which is used to select an operational mode of the stapler. A locking linking mechanism, when in its locked position, holds the anvil member adjacent to the cartridge assembly allowing closure of the staple to occur. The devices are intended for one hand use.
