An endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes a frame portion, an elongated portion extending from the frame portion, and an articulating fastener applying assembly associated with a distal end of the elongated portion. The fastener applying assembly includes a base portion, a staple cartridge housing, and an anvil member which has a forming surface thereon against which surgical fasteners are driven as they are ejected from the cartridge housing. A first mechanism is provided for effectuating the rotation of the fastener applying assembly about an axis defined by the body portion, a second mechanism is provided for effectuating the articulation of the fastener applying assembly, and a third mechanism is provided for independently rotating the cartridge housing and anvil member relative to a longitudinal axis defined by the base position to increase the range of operability of the apparatus.

Surgical stapling apparatus

A site marker device and marker are provided. The site marker device includes a housing and a distally extending delivery tube. A pusher rod is movably positioned within the delivery tube to eject a marker from the distal end thereof. An elongated tubular body is positioned about the delivery tube. An actuator is provided to provide two stage advancement. During the first stage, the delivery tube and the pusher rod are advanced through the distal end of the elongated tubular body. During the second stage of advancement, the pusher rod is advanced independently of the delivery tube to eject a marker from the distal end thereof. The marker is formed from a shape memory material and has a circular or hoop configuration in the relaxed state.

Site marker device

A surgical stapler is disclosed including a first body portion supporting an anvil plate defining a fastener forming surface, and a second body portion releasably mating with the first body portion. A disposable loading unit is removably supported in the second body portion and includes a cartridge defining a plurality of slots, a plurality of surgical fasteners disposed in the slots, a plurality of ejectors positioned adjacent the surgical fasteners, and a wedged actuator for sequentially interacting with the ejectors. An elongated actuation member is mounted for longitudinal movement within the second body portion and is releasably engageable with the wedged actuator. A locking mechanism having a locking member and a biasing member is included in the second body portion.

Surgical stapler

A surgical stapler is disclosed which includes a first body portion supporting an anvil plate defining a fastener forming surface, and a second body portion configured to releasably mate with the first body portion. A disposable loading unit is removably supported in the second body portion and includes a cartridge defining a plurality of slots, a plurality of surgical fasteners disposed in the slots, a plurality of ejectors positioned adjacent the surgical fasteners, and a wedged actuator configured to enter into and translate through the cartridge to sequentially interact with the ejectors. An elongated actuation member is mounted for longitudinal movement within the second body portion and is releasably engagable with the wedged actuator, whereby longitudinal movement of the actuation member causes the wedged actuator to interact with the ejectors, driving the surgical fasteners from the cartridge to be formed against the anvil plate.

A surgical apparatus for securing a needle extending therethrough includes a post having a channel therein mounted to a base. The post is positioned in operative alignment with the needle mounted on the base. A locking member is associated with the post in operative alignment with the needle. The locking member defines an opening therethrough to receive the needle, and the locking member is operable between a needle receiving position wherein the needle may be inserted or removed from the locking member and a needle retaining position wherein the needle is retained in at least one direction of movement. A method for surgically localizing and removing tissue includes the steps of providing a tissue cutting member mounted on a base and defining an opening near a distal end, the tissue cutting member further forming a tissue receiving cavity in communication with the opening, a needle disposed within the cavity and defining a longitudinal passageway therethrough, a post mounted on the base and a locking member mounted on the post and defining having a needle receiving opening in operative alignment with the needle, the locking member being operable between a needle receiving position wherein the needle may be inserted or removed from the locking member and a needle retaining position wherein the needle is retained in at least one direction of movement, locking the needle within the locking member by rotating the locking member into the needle retaining position, positioning the needle within target tissue, severing the tissue to be removed and removing the severed tissue from a patient.
