Abstract
Abstract A scissor-type surgical stapler is disclosed in which a pair of pivotally connected forcep handles are used with an elongated cartridge housing at the forward end of one of the handles, this cartridge housing being adapted to hold a staple cartridge containing a plurality of staples positioned in a line along the length of the housing, and an anvil is positioned in parallel apposition to the cartridge housing in line with the staples to be ejected from the staple cartridge, the anvil and the cartridge housing being interlinked so as to be relatively movable toward and away from each other while maintaining said parallel apposition as the handles are moved to open and close the staples.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
113 words
A surgical stapler comprising an elongated cartridge housing of channel cross-section, said cartridge housing being adapted to hold at the open upper end of said channel a staple cartridge containing a plurality of staples positioned in a line along the length of the cartridge housing, said staple cartridge having the staples thereof positioned at the upper portion of the cartridge overlying a lifter which, when lifted, will cause the ejection of all of the staples, movable lifting rods extending across the lower portion of the channel of said cartridge housing, and means movable at an angle to the movement of said rods to cause said rods to be elevated to lift said lifter.
Claim 2
Dependent Claim
113 words
A surgical stapler comprising an elongated cartridge housing of channel cross-section, said cartridge housing being adapted to hold at the open upper end of said channel a staple cartridge containing a plurality of staples positioned in a line along the length of the cartridge housing, said staple cartridge having the staples thereof positioned at the upper portion of the cartridge overlying a lifter which, when lifted, will cause the ejection of all of the staples, movable lifting rods extending across the lower portion of the channel of said cartridge housing, and means movable at an angle to the movement of said rods to cause said rods to be elevated to lift said lifter.
Claim 3
Dependent Claim
214 words
A scissor-type surgical stapler comprising a pair of pivotally connected forcep handles movable from an open position to a closed position, an elongated cartridge housing of channel shape at the forward end of one of said forcep handles, said cartridge housing being adapted to hold a staple cartridge containing a plurality of staples positioned in a line along the length of the cartridge housing, actuator means associated with said cartridge housing for operating said staple cartridge to cause the ejection of staples therefrom, said actuator means being constituted by a U-shaped member embracing the exterior of said cartridge housing, an anvil positioned in parallel apposition to said cartridge housing in line with the staples to be ejected from said staple cartridge, said anvil and said cartridge housing being interlinked so as to be relatively movable toward and away from each other while maintaining said parallel apposition as said handles are moved between said open and closed positions, and said cartridge housing and U-shaped actuator having at least one pair of crossing slots with a rod extending through each of said pairs of crossing slots and through the lower portion of the channel of said cartridge housing to underlie the staple cartridge when it is positioned in said cartridge housing, to operate said actuator means.
