A surgical stapler instrument is provided for applying lateral lines of staples to tissue while cutting the tissue between those staple lines. The instrument includes a handle portion, an implement portion, a reciprocating section, a drive member and a movable actuator. The implement portion includes a staple cartridge and an anvil. The reciprocating section is adapted to move back and forth along an axis of the implement portion. The movable actuator is associated with the handle portion and is engaged with the drive member such that motion of the actuator causes the drive member to move back and forth between first and second drive positions separated by a first distance. Further structure is provided to position only a correct amount of tissue (a predetermined range) between the anvil and cartridge. A multiplier is further provided and is associated with the reciprocating section and the drive member for causing the reciprocating section to move back and forth between first and second reciprocating positions in response to movement of the drive member. The reciprocating section includes a work portion which, when moved distally, effects the firing of staples in the staple cartridge toward the anvil. The work portion is also provided with a reciprocating knife. The first and second reciprocating positions are separated by a second distance which differs from the first distance.
A surgical stapler instrument (100) comprising: an implement portion (110) having an elongated channel (112) releasably receiving a staple cartridge (120) therein, said cartridge housing a plurality of drivers (122a-122d), each of said drivers supporting one or more staples (124), and an anvil (114)
A surgical stapler instrument (100) comprising: an implement portion (110) having an elongated channel (112) releasably receiving a staple cartridge (120) therein, said cartridge housing a plurality of drivers (122a-122d), each of said drivers supporting one or more staples (124), and an anvil (114) movable toward and away from said cartridge for clamping bodily tissue (200) and thereafter releasing said bodily tissue positioned between said anvil and said cartridge after said staples have been fired; a handle portion (130) having a base section (130a), and a closure trigger (150) including an elongated, generally linear handle section (150a) having a longitudinal axis, said closure trigger pivotally mounted in said handle portion for pivoting said handle section from a first handle position spaced from said base section to a second handle position adjacent said base section, said closure trigger normally biased toward said first handle position; a closure tube (152) having a proximal end connected to said handle portion and a distal end being adapted to engage said anvil for effecting movement of said anvil toward and away from said cartridge when said handle section of said closure trigger is pivoted to and from said first and second handle positions; a closure yoke (154) reciprocatable within said handle portion from a first proximal yoke position to a second intermediate and third distal yoke positions, respectively, said yoke having distal and proximal ends, said distal end of said yoke being connected to said proximal end of said closure tube and said proximal end of said yoke connected to said closure trigger such that pivotal movement of said handle section of said closure trigger from said first handle position to said second handle position effects movement of said closure tube; and a releasable locking assembly (138) mounted in said handle portion and engageable with said yoke only when said yoke is in said third distal yoke position so as to lock said handle section of said closure trigger in said second handle position adjacent said base section of said handle portion and prevent said handle section from returning to said first handle position when said pivotal movement is released; wherein said closure yoke includes a sliding surface (154h) and a recessed surface (154f), and said releasable locking assembly includes a release button pivotally mounted in said handle portion, said release button having a latch arm (138a) slidable on said sliding surface of said yoke when said yoke reciprocates from said first proximal yoke position to said second intermediate yoke position, and said latch arm pivotably engages said recessed surface so as to prevent proximal reciprocating movement of said yoke when said yoke is in said third distal yoke position.
