摘要： An improved surgical stapler for applying a suture to a tissue is provided. The surgical stapler includes handles and a stapling assembly for emplacing a suture and staples into tissue as a purse string suture. Retainer structure, for example, a plurality of guides are provided for releasably retaining a portion of the suture substantially adjacent to the handles. The suture may also be releasably retained substantially adjacent to the handles by passing the suture through a tubular member releasably mounted on one of the handles. A clamp may be used to clamp and secure the suture within the tubular member either before or after removal of the tubular member from the handles.

摘要： A surgical apparatus for attaching two portions of cutaneous body tissue includes a pair of opposed elongated members having jaws which have tissue gripping members thereon at one end and which are movable toward each other to a closed position to engage two body tissue portions positioned within the members to move the body tissue portions into close approximation. Manually gripping systems of several alternative configurations are provided to actuate a mechanical transmission system to close the jaws. In a preferred embodiment, a fork is movable from a first position to a second position by manually operable devices to move the jaws toward each other. A pair of cam faces is located adjacent the opposite ends of the jaws. As the fork moves to its second position, the tines of the fork engage against the cam faces to move the opposed jaws to their closed position. A plurality of rod-like fasteners are carded in a stacked configuration proximally of the jaws such that when the jaws are in their closed position and the two body tissue portions are held in close approximation. Each rod-like fastener is movable to a position in ingress to penetrate the body tissue portions to attach the body tissue portions together. In another preferred embodiment, the elongated members are biased outwardly by a coil spring and a unique plate-like fastener drive member is provided to facilitate driving a fastener after the jaws are closed. A fastener cartridge is provided with fasteners stacked in a sloped fashion and having a coil spring to bias the fasteners toward the ejection position. Another embodiment includes a rack and gear teeth arrangement for approximating the jaws and for firing the fasteners. The rack and gear teeth function somewhat like a linear analog of a set of rotary gears. A method of attaching cutaneous body tissue portions is also disclosed.
