Abstract:
A tool assembly for a surgical stapling device includes a channel member for supporting a staple cartridge therein and an anvil to deform a plurality of staples ejected from the staple cartridge thereagainst. The tool assembly also includes a sled which is movable to force the staples from the cartridge against the anvil to staple tissue disposed between the anvil and the staple cartridge. A dynamic clamping member is included which has a pin which movably engages the anvil and a flange which movably engages the channel assembly. The dynamic clamping member is mounted to and movable with the sled. The pin and the flange of the dynamic clamping member cooperating to oppose the forces associated with clamping and stapling tissue and also to maintain a substantially uniform gap between the anvil and the staple cartridge during stapling of the tissue.

Claim (Index 16):
A surgical tool for performing robotic surgery, the surgical tool comprising:\n a shaft having a proximal end and a distal end, the proximal end being removably associated with a robotic system; and a tool assembly, the tool assembly comprising:\n a clamping member comprising:\n a lower transverse member comprising first and second transverse protrusions extending in substantially opposite directions, each of the first and second transverse protrusions having an upper engagement surface, \n an upper transverse member comprising third and fourth transverse protrusions extending in substantially opposite directions, and \n an upward extension extending between and connecting the lower transverse member and the upper transverse member substantially perpendicular to the lower transverse member and the upper transverse member, the upper transverse member and the lower transverse member being substantially transverse to the upward extension, \n \n a first jaw comprising:\n a proximal end, \n a distal end, \n the first jaw having a support channel between the proximal end of the first jaw and the distal end of the first jaw, the support channel being configured to receive a staple cartridge assembly, the staple cartridge assembly having at least one tab, a longitudinal slot, and at least three rows of staples disposed on each side of the longitudinal slot, the at least three rows of staples on each side of the longitudinal slot being substantially parallel to the longitudinal slot, the first jaw further comprising at least one aperture along an edge of the first jaw, and the at least one tab of the staple cartridge being engageable with the at least one aperture of the first jaw, at least the at least one aperture and the at least one tab being configured to cooperate to removably and replaceably retain the staple cartridge within the elongated channel, and \n a surface of the first jaw having a longitudinal slot between the proximal end of the first jaw and the distal end of the first jaw, the surface of the first jaw being configured to engage with the upper engagement surfaces of the first and second transverse protrusions of the lower transverse member of the clamping member as the upward extension travels through the longitudinal slot such that the first and second transverse protrusions slide along the surface of the first jaw, a second jaw pivotable relative to the first jaw, the second jaw comprising: \n a proximal end, \n a distal end, \n an anvil having at least one anvil surface, the at least one anvil surface having at least one staple forming pocket, and \n the anvil having an elongated slot between the proximal end of the second jaw and the distal end of the second jaw, the elongated slot being configured to receive the third and fourth transverse protrusions of the upper transverse member of the clamping member as the upward extension travels through the elongated slot, \n \n wherein movement of the clamping member along the first and second jaws such that the upper engagement surfaces of the first and second transverse protrusions of the lower transverse member of the clamping member move along the surface of the first jaw and the third and fourth transverse protrusions of the upper transverse member of the clamping member move through the elongated slot and causes at least one of:\n the first and second jaws to clamp, and \n staples to be ejected from the staple cartridge assembly when a staple cartridge assembly is received within the support channel of the first jaw, and \n \n a connection mechanism connecting the tool assembly to the shaft, the connection mechanism comprising:\n a first pivot axis being substantially perpendicular to a longitudinal axis of the shaft, wherein the tool assembly is pivotable about the first pivot axis with respect to the shaft, and \n a second pivot axis being substantially perpendicular to the first pivot axis, wherein the tool assembly is pivotable about the second pivot axis with respect to the shaft.
