A firing mechanism is positioned within the housing movable to a second position to effect firing of fasteners. A power pack is removably loadable into the compartment, the power pack having one or both of a) a first motor and a first engagement member removably engageable with the firing mechanism when the power pack is loaded into the compartment to effect movement of the firing mechanism; and b) a second motor and a second engagement member removably engageable with an articulating mechanism in the housing of the surgical fastener applier to effect movement of an articulation mechanism to effect articulation. One or both of a firing position and an articulation position are tracked during the surgical procedure. Sensors are provided to detect select parameters and instrument functions. ## Claims ### Claim 1 A surgical fastener applier comprising: a housing; an elongated member extending distally of the housing and having a longitudinal axis; a first jaw and a second jaw, at least the first jaw movable with respect to the second jaw to a clamping position to clamp tissue between the first and second jaws; a jaw clamping mechanism, the clamping mechanism including a clamping member movable to move at least the first jaw toward the second jaw to clamp the tissue between the first and second jaw; and a cartridge devoid of fasteners positioned in one of the first and second jaws, wherein a staple height size for a fastener cartridge is determined by the cartridge positioned in one of the first and second jaws. ### Claim 2 (depends on 1) The surgical fastener applier of claim 1, wherein the fastener applier further comprises a motor powered firing mechanism positioned within the housing, the firing mechanism movable between a first position and a second position, wherein movement to the second position effects firing of fasteners into the tissue clamped between the first and second jaws. ### Claim 3 (depends on 2) The surgical fastener applier of claim 2, wherein the fastener applier comprises a motor powered articulation mechanism positioned within the housing, the articulation mechanism movable between a first position and a second position to move the first and second jaws to a position angled with respect to the longitudinal axis of the elongated member, wherein the first and second jaws are articulable in a first direction with respect to the longitudinal axis and articulable in a second direction with respect to the longitudinal axis. ### Claim 4 (depends on 3) The surgical fastener applier of claim 3, further comprising a screen to indicate a firing position and an articulated position. ### Claim 5 (depends on 1) The surgical fastener applier of claim 1, wherein the fastener applier comprises a motor powered articulation mechanism positioned within the housing, the articulation mechanism movable between a first position and a second position to move the first and second jaws to a position angled with respect to the longitudinal axis of the elongated member, wherein the first and second jaws are articulable in a first direction with respect to the longitudinal axis and articulable in a second direction with respect to the longitudinal axis. ### Claim 6 (depends on 1) The surgical fastener applier of claim 1, wherein the cartridge devoid of fasteners is a dummy cartridge without any fasteners, the dummy cartridge loaded into one of the first and second jaws prior to firing of any fasteners. ### Claim 7 (depends on 1) The surgical fastener applier of claim 1, wherein jaw clamping is manually actuated. ### Claim 8 (depends on 1) The surgical fastener applier of claim 1, wherein proximal movement of the clamping member clamps the first and second jaws on tissue. ### Claim 9 (depends on 8) The surgical fastener applier of claim 8, wherein movement of the clamping member to clamp the first and second jaws is effected by a cam slot and pin arrangement. ### Claim 10 (depends on 9) The surgical fastener applier of claim 9, further comprising a clamp force measurement device, the measurement device in line with the clamping member and at a handle housing of the fastener applier. ### Claim 11 (depends on 1) The surgical fastener applier of claim 1, wherein a cartridge load is determined for indicating the fastener cartridge. ### Claim 12 (depends on 1) The surgical fastener applier of claim 1, wherein the staple height size is outputted to a screen. ### Claim 13 (depends on 12) The surgical fastener applier of claim 12, wherein the screen is provided on the fastener applier. ### Claim 14 (depends on 12) The surgical fastener applier of claim 12, wherein the screen is provided on a power pack removably inserted into the fastener applier. ### Claim 15 (depends on 12) The surgical fastener applier of claim 12, wherein the staple height size is determined by clamping the cartridge on tissue. ### Claim 16 (depends on 1) The surgical fastener applier of claim 1, further comprising a clamping indicator indicating where in a range tissue falls based on cartridge selected. ### Claim 17 (depends on 1) The surgical fastener applier of claim 1, wherein after the staple height size is determined, the cartridge is removed and replaced with a second cartridge having fasteners, and a firing mechanism of the surgical fastener applier is activated to fire the fasteners. ### Claim 18 (depends on 17) The surgical fastener applier of claim 17, wherein the firing mechanism is motor driven. ### Claim 19 (depends on 18) The surgical fastener applier of claim 18, further comprising a screen to indicate a firing position.
