  • Patent number: 9326761
    Abstract: An access device includes a body, a first tube, a second tube, and a mechanism. The first and second tubes extend through the body. The mechanism operably couples the first and second tubes such that at least one tube is pivotable about an axis with respect to the other tube. The body may form a substantially fluid-tight seal at the incision. In another embodiment, the access device further includes a third tube extending through the body and the mechanism operably couples the tubes together such that at least two tubes are pivotable about the axis with respect to the remaining tube.

  • Patent number: 9005238
    Abstract: According to an aspect of the present disclosure, an endoscopic surgical device is provided and includes a handle assembly; a tube assembly operatively supported on and extending from the handle assembly, the tube assembly defining a longitudinal axis; an articulation assembly operatively supported on and extending from a distal end of the tube assembly; and a tool assembly operatively supported on and extending from a distal end of the articulation assembly. In use, a rotation of the handle assembly about the longitudinal axis results in a concomitant rotation of the tool assembly; an actuation of the handle assembly in a particular manner results in a concomitant actuation of the tool assembly; and a pivoting of the handle assembly in any off-axis direction relative to the longitudinal axis results in a concomitant articulation of the tool assembly via the articulation assembly.

  • Publication number: 20140303640
    Abstract: A specimen retrieval pouch (pouch) is provided. The pouch including a closed bottom portion, an open upper portion and an elongated tube operably coupled to an interior wall of the pouch. The elongated tube has a plurality of openings positioned along a length thereof. A suture accessible at a proximal end of the pouch is positioned within the elongated tube and extends past a distal end thereof. The suture is movable within the elongated tube and relative to the pouch. The suture has either a needle or a loop at a distal end thereof for attaching to tissue and subsequently drawing the tissue into the pouch when the suture is pulled. One or more reinforced tabs are operably disposed on the pouch. The reinforced tab(s) is/are configured to be grasped by a user to provide a counter pull force as the suture is being pulled through the elongated tube.
