Abstract
Abstract A fastener applying device for applying surgical fasteners to body tissue is provided. The fastener applying device includes an approximation mechanism having a single actuator to perform fast closure and incremental approximation of a cartridge carrier and anvil. The cartridge carrier and anvil can be approximated into a multiplicity of predetermined firing enabled positions. An adjustment member is operably associated with a firing mechanism of the device to vary the maximum stroke of a pusher bar. The adjustment member facilitates ejection of multiple size fasteners from the device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
A device for applying a plurality of surgical fasteners to body tissue, the device comprising: a housing having a distally extending body portion; an anvil and a cartridge carrier supported at a distal end of the housing for relative movement; an approximation mechanism operably associated with the cartridge carrier and being movable to approximate the cartridge carrier and the anvil; a pusher bar extending within the housing, the pusher bar being movable over a predetermined stroke to effect ejection of fasteners from a cartridge positioned in the cartridge carrier; and an adjustment member operably associated with the pusher bar to selectively vary the stroke of the pusher bar to accommodate ejection of different size fasteners from the device.
Claim 2
Independent Claim
118 words
A device for applying a plurality of surgical fasteners to body tissue, the device comprising: a housing having a distally extending body portion; an anvil and a cartridge carrier supported at a distal end of the housing for relative movement; an approximation mechanism operably associated with the cartridge carrier and being movable to approximate the cartridge carrier and the anvil; a pusher bar extending within the housing, the pusher bar being movable over a predetermined stroke to effect ejection of fasteners from a cartridge positioned in the cartridge carrier; and an adjustment member operably associated with the pusher bar to selectively vary the stroke of the pusher bar to accommodate ejection of different size fasteners from the device.
Claim 3
Dependent Claim
32 words
A device according to claim 1, wherein the adjustment member is movable to different positions of engagement with respect to the pusher bar to selectively vary the stroke of the pusher bar.
Claim 4
Dependent Claim
33 words
A device according to claim 2, wherein the adjustment member includes at least two abutment surfaces, the adjustment member being movable to selectively position the abutment surfaces for engagement with the pusher bar.
Claim 5
Dependent Claim
43 words
A device according to claim 3, wherein the pusher bar includes an adjustment slot having a stop surface, the adjustment member extending through the adjustment slot and being movable to selectively position one of the abutment surfaces for engagement with the stop surface.
Claim 6
Dependent Claim
14 words
A device according to claim 4, wherein the adjustment member includes a rotatable shaft.
Claim 7
Dependent Claim
26 words
A device according to claim 5, wherein the at least two abutment surfaces are formed as circumferentially spaced recesses on a periphery of the rotatable shaft.
Claim 8
Dependent Claim
45 words
A device according to claim 1, wherein the pusher bar includes a plurality of integrally formed distally extending fingers, the pusher bar being movable with respect to the cartridge carrier to engage and effect ejection of fasteners from a cartridge positioned in the cartridge carrier.
Claim 9
Dependent Claim
37 words
A device according to claim 7, further including a cavity formed in the distal end of the pusher bar, wherein the pusher bar is constructed of plastic and a metal support plate is positioned in the cavity.
Claim 10
Dependent Claim
40 words
A device according to claim 1, further comprising an alignment mechanism including lateral and longitudinal alignment members operably connected to the approximation mechanism to align the cartridge carrier and the anvil during approximation of the anvil and the cartridge carrier.
