Abstract: A surgical stapler includes a body portion and a tool assembly. The body portion includes a large diameter portion and a small diameter portion extending distally from the large diameter portion. The large diameter portion supports larger internal components of the device including a lockout assembly adapted to prevent refiring of the stapler to allow the diameter of the small diameter portion of the device to be minimized to facilitate passage of the small diameter portion of the stapler and the tool assembly through an 8 mm trocar.

Abstract: An adapter assembly includes a cam housing defining a proximal cam slot and a distal cam slot, a first elongate shaft, and a second elongate shaft. The first elongate shaft has a proximal end portion received in the proximal cam slot, and a distal end portion configured to be coupled to a surgical loading unit. The second elongate shaft has a proximal end portion received in the distal cam slot, and a distal end portion configured to be coupled to the surgical loading unit. The first and second elongate shafts are configured to move in opposing longitudinal directions in response to a rotation of the cam housing to articulate the surgical loading unit.

Abstract: A surgical apparatus for application of surgical clips to body tissue is provided. The surgical apparatus includes a housing, a drive assembly, a trigger, and a shaft assembly. The trigger is operatively connected with the drive assembly. The drive assembly is at least partially positioned within the housing. The shaft assembly extends distally from the housing and has a first tubular member pivotally connected with a second tubular member located distally from the first tubular member. An articulation mechanism is operatively connected between the first and second tubular members, and includes a gear rack, at least one gear, and a gear segment, respectfully connected with each other to pivot the second tubular member about the pivot axis. The gear rack and at least one gear are located within the first tubular member. The gear segment extends proximally from the second tubular member.
