Abstract

A medical suturing device is provided which basicly includes a base, a bridge and a head. The bridge extends between and is attached at its ends to the base and the head. The head receives the staples therein (in a staple cartridge) and includes the mechanism to fire the staples. The base includes an anvil which the ends of the staples contact when they are driven through a workpiece. The staple driving mechanism includes an H-shaped body member which receives the cartridge of staples in the lower half of the 'H', a rod-like wedge which is slidably received in the upper half of the 'H', a rocker plate which is attached perpendicularly to the body member, a rocker arm which is rotatably attached to the rocker plate and interfaces a portion of the wedge, a staple driver which extends between and interfaces the wedge and the staples, and a pneumatic rod which extends from a pneumatic inlet and interfaces the rocker arm. The pneumatic rod is slidable between an in and an extended position. When a pneumatic cylinder is attached to the bolt, and when the pneumatic cylinder is activated, the pneumatic rod slides from the in to the extended position, rotating the rocker arm with respect to the rocker plate, which in turn slides the wedge within the body member driving the staple driver and thus the staples downward through the workpiece.
