Abstract: A surgical device for performing surgery generally includes a handle assembly, an elongate member extending from the handle assembly, an articulation mechanism operatively associated with the handle assembly, and an end effector. The elongate member has an articulating section and straight section. The articulating section is configured to articulate with respect to the straight section. The articulation mechanism is operatively associated with the handle assembly and the articulating section such that the articulating section articulates toward a first direction relative to the straight section upon movement of the handle assembly towards the first direction with respect to the straight section. The end effector is operatively coupled to the articulating section of the elongate member and includes first and second jaw members. The surgical device further includes a locking mechanism configured for fixing a relative position of first and second jaw members.

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.
