A surgical device is disclosed which includes a handle assembly, an elongated member and a disposable loading unit. The handle assembly includes a mode selection mechanism configured to alternate the surgical device between a first grasping mode of operation and a second clamping mode of operation.
A surgical device is disclosed which includes a handle assembly, an elongated member and a disposable loading unit. The handle assembly includes a mode selection mechanism configured to alternate the surgical device between a first grasping mode of operation and a second clamping mode of operation. The handle assembly includes a rotation control member and an articulation lever. The rotation control member is configured to facilitate rotation of the elongated member with respect to the handle assembly. The articulation lever is configured to facilitate articulation of the tool assembly about an axis substantially perpendicular to the longitudinal axis of elongated member. In one embodiment, the tool assembly includes a cartridge assembly having a plurality of staples and an anvil assembly configured to clamp and staple tissue in the second clamping mode of operation of the device.
What is claimed is: 1. A surgical device comprising:a handle assembly including an actuation shaft, a stationary handle, and a movable handle, the movable handle being operably associated with the actuation shaft such that movement of the movable handle effects axial movement of the actuation shaft;
What is claimed is: 1. A surgical device comprising:a handle assembly including an actuation shaft, a stationary handle, and a movable handle, the movable handle being operably associated with the actuation shaft such that movement of the movable handle effects axial movement of the actuation shaft;an elongated member extending distally from the handle assembly, the elongated member defining a longitudinal axis;a tool assembly mounted to a distal end of the elongated member, the tool assembly having a cartridge assembly having a plurality of staples supported therein and an anvil assembly, at least one of the anvil assembly and the cartridge assembly being movable in relation to each other between open and closed positions;a mode selection mechanism configured to alternate the surgical device between a first mode of operation and a second mode of operation, the mode selection mechanism including a switch for selecting between the first mode of operation, in which the cartridge assembly and anvil assembly are movable back and forth between the open and closed positions, and the second mode of operation, in which the cartridge assembly and anvil assembly clamp tissue;a cam assembly operably associated with a vertical pawl, the vertical pawl being movable from a first position engaged with the actuation shaft to prevent axial movement of the actuation shaft and a second position disengaged from the actuation shaft to permit axial movement of the actuation shaft; andan arm movable between a first position engaged with the actuation shaft and a second position disengaged from the actuation shaft, the cam assembly configured to move the vertical pawl to its second position upon movement of the movable handle when the arm is in its first position and the cam assembly being configured to allow movement of the vertical pawl from its second position to its first position upon movement of the movable handle when the arm is in its second position.
