  • Patent number: 7891533
    Abstract: 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.

  • Patent number: 6488636
    Abstract: An apparatus and method for the biopsy of tissue specimens and, more particularly, a single insertion multiple sample percutaneous biopsy apparatus and method are provided. A tip at a distal end of a vacuum support tube is introduced into a tissue mass. The vacuum support tube is retracted exposing a basket tube bounded by a front washer and a rear washer mounted thereabout forming a tissue basket. The basket tube is supported internally by a thrust tube which provides structure to the apparatus to allow it to penetrate tissue. The thrust tube and the basket tube are in fluid connection and are provided with suction to draw tissue inward. The tissue is then severed by rotating and advancing a knife edge at the distal end of the vacuum support tube. The tissue basket is withdrawn and the tissue sample is removed by rotating the vacuum support tube. The tissue sample is sliced longitudinally, and a stripper scrapes the tissue sample from an opening in the vacuum support tube.
