Abstract

Abstract A surgical stapling instrument with a remotely articulated staple head assembly on a rotatable support shaft. A joy stick mounted to the shaft of the instrument near the handle allows for remote articulation of the staple head assembly. The staple head assembly includes a narrow contour for insertion between adjacent rib pairs without rib spreading. The staple head assembly further includes a reloadable staple cartridge which may be replaced with differently sized staples of a second cartridge. A closure trigger clamps tissue prior to stapling and cooperates with a second trigger that performs the staple firing operation. The triggers include a safety lock mechanism for preventing premature staple firing.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 232 words
A surgical instrument for applying one or more surgical fasteners to tissue, comprising: an articulatable fastener applying assembly including a proximal moveable jaw, said proximal moveable jaw including fastener holding means including a reloadable fastener cartridge for holding one or more surgical fasteners, means for driving said surgical fasteners into the tissue, a distal jaw including anvil means for forming said surgical fasteners about the tissue, means for capturing and clamping said tissue prior to forming said fasteners and for releasing said tissue after forming said fasteners; a shaft assembly for articulatably mounting to the distal end thereof said fastener applying assembly; an actuator handle assembly mounted to the proximal end of said shaft assembly and including means for actuating said means for driving said surgical fasteners wherein said fastener applying assembly includes pulley means for reversing direction of a pull cable, said pull cable having two ends, said pull cable being anchored at one end to said fastener holding means and at its other end to actuator means of said actuator handle assembly, whereby as said actuator means is acted upon by a pulling motion, said pull cable translates said pulling motion of said actuator means into distal motion of said fastener holding means, thereby moving said proximal moveable jaw distally toward said distal jaw; said fastener applying assembly sized and contoured for insertion between human ribs without spreading said ribs.
Claim 2
Dependent Claim 232 words
A surgical instrument for applying one or more surgical fasteners to tissue, comprising: an articulatable fastener applying assembly including a proximal moveable jaw, said proximal moveable jaw including fastener holding means including a reloadable fastener cartridge for holding one or more surgical fasteners, means for driving said surgical fasteners into the tissue, a distal jaw including anvil means for forming said surgical fasteners about the tissue, means for capturing and clamping said tissue prior to forming said fasteners and for releasing said tissue after forming said fasteners; a shaft assembly for articulatably mounting to the distal end thereof said fastener applying assembly; an actuator handle assembly mounted to the proximal end of said shaft assembly and including means for actuating said means for driving said surgical fasteners wherein said fastener applying assembly includes pulley means for reversing direction of a pull cable, said pull cable having two ends, said pull cable being anchored at one end to said fastener holding means and at its other end to actuator means of said actuator handle assembly, whereby as said actuator means is acted upon by a pulling motion, said pull cable translates said pulling motion of said actuator means into distal motion of said fastener holding means, thereby moving said proximal moveable jaw distally toward said distal jaw; said fastener applying assembly sized and contoured for insertion between human ribs without spreading said ribs.
Claim 3
Dependent Claim 12 words
The surgical instrument of claim 1 wherein said pull cable comprises Vectran®.
Claim 4
Dependent Claim 14 words
The surgical instrument of claim 2 wherein said pull cable comprises a continuous loop.
Claim 5
Dependent Claim 14 words
The surgical instrument of claim 1 wherein said fastener applying assembly is remotely articulatable.
Claim 6
Dependent Claim 13 words
The surgical instrument of claim 1 wherein said fastener assembly is remotely rotatable.
Claim 7
Dependent Claim 35 words
The surgical instrument of claim 1 wherein said means for capturing said tissue includes an alignment pin operable to reciprocate within said fastener holding means and seat within said anvil means, thereby capturing said tissue.
Claim 8
Dependent Claim 21 words
The surgical instrument of claim 1 wherein said fastener holding means is adapted for receiving at least two different size fasteners.
Claim 9
Dependent Claim 78 words
The surgical instrument of claim 7 wherein said fastener cartridge includes one or more spacing means comprising protuberances on a surface thereof abutting said anvil means for maintaining a predetermined spacing between said surface and said anvil means and thereby forming a fastener of predetermined formed size, said reloadable fastener holding means adapted for receiving multiple fastener cartridges each having differently sized spacing means for varying the size of a formed fastener produced by each respective fastener cartridge.
Claim 10
Dependent Claim 25 words
The surgical instrument of claim 1, further including seal means for maintaining a pressure gradient between the distal and proximal ends of said shaft assembly.
