A surgical apparatus is provided for penetrating body tissue. The apparatus includes a cannula and an obturator configured for insertion into the cannula. The obturator has a body tissue cutting member mounted to a distal portion which is movable between deployed and non-deployed positions. An actuating mechanism is operatively associated with the tissue cutting member and is selectively controllable by a user so as to move the tissue cutting member between the deployed and non-deployed positions independent of the position of the obturator.

Trocar having movable blade

A surgical instrument for percutaneous accessing body tissue including a tissue piercing element for creating an opening through a body wall. The surgical instrument may include a working member for performing a surgical procedure within the body. Alternatively, the surgical instrument may include an introducer having a stabilizing structure for facilitating the passage of the tissue piercing element and for releasably affixing the surgical instrument to the body tissue surface, thereby securing the surgical instrument relative to the patient's body.

Percutaneous introducer

A fastener for securing adjacent layers of body tissue to each other and being configured and composed of a material so as to emerge from the body tissue after a limited period of time. The fastener includes a backspan and at least two prongs extending from the backspan. Each prong has a tapered tip culminating in a sharp point. The prongs each include a shaft having a cylindrical portion of uniform diameter. In one embodiment, the prong includes a serrated portion having a plurality of notches spaced apart so as to define ridge portions there between. In another embodiment, the prong includes a pair of tapered projecting surfaces extending around a portion thereof.

Skin fastener

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.

Purse string stapler

A device for positioning a surgical instrument having an elongated portion, the device comprising a housing having an opening therethrough to receive the elongated instrument portion and an actuation member mounted to said housing and movable between a first position and a second position. The actuation member overlaps a portion of said opening in said second position to prevent movement of the elongated portion of the instrument. The actuation member may be movable along a plane parallel, perpendicular or lateral to a longitudinal axis of the surgical instrument.

Surgical instrument positioning device

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.
