Abstract
Abstract Surgical fastener applying apparatus having an articulated shaft assembly (100) intermediate a proximal actuator assembly (20) and a distal fastener applying assembly (200). The rotational axis of the articulation (112) is transverse to the proximal-distal axis of the shaft assembly (102). The apparatus is fully operational at any rotational position of the articulation (110). A detent mechanism (116) may be included to releasably hold the articulation in any of its rotational positions. A locking mechanism (190) may also be provided for locking the articulation in any of its rotational positions. The shaft assembly (100) may also include a second articulation whose rotational axis is the proximal-distal axis (102). The apparatus is fully operational at any rotational position of the second articulation, and detent and locking mechanisms may also be associated with the second articulation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
87 words
A surgical fastener applying apparatus having a proximal actuator assembly (20), a distal fastener applying assembly (220) and an intermediate shaft assembly (100) connecting said actuator assembly (20) to said fastener applying assembly (200) characterized in that said fastener applying assembly (200) is manually rotatable about a longitudinal axis (102) of said shaft assembly (100) relative to said actuator assembly (20) and in that said fastener applying assembly (200) is manually rotatable about a second axis (112) perpendicular to said axis (112) of said shaft assembly (100).
Claim 2
Dependent Claim
87 words
A surgical fastener applying apparatus having a proximal actuator assembly (20), a distal fastener applying assembly (220) and an intermediate shaft assembly (100) connecting said actuator assembly (20) to said fastener applying assembly (200) characterized in that said fastener applying assembly (200) is manually rotatable about a longitudinal axis (102) of said shaft assembly (100) relative to said actuator assembly (20) and in that said fastener applying assembly (200) is manually rotatable about a second axis (112) perpendicular to said axis (112) of said shaft assembly (100).
Claim 3
Dependent Claim
38 words
A surgical fastener applying apparatus as set forth in claim 1 characterized in having a first articulation (140) between said shaft assembly (100) and said fastener applying assembly (200) to permit rotation therebetween about said longitudinal axis (102).
Claim 4
Dependent Claim
100 words
A surgical fastener applying apparatus as set forth in claim 2 characterized in that said shaft assembly (100) includes a first tube (160) rotatably receiving said articulation (140), a second tube (170) keyed to said articulation (140) and rotatably mounted on said first tube (160) and a rotatable locking ring (190) mounted on said first tube (160) between said actuator assembly (20) and said second tube (170), said locking ring (190) being rotatable between a first position to permit relative rotation between said tubes (160, 170) and a second position to releasably hold said tubes (160, 170) in locked relation.
Claim 5
Dependent Claim
66 words
A surgical fastener applying apparatus as set forth in claim 3 further characterized in having a collar (180) with teeth (182) mating with teeth (176) on said second tube (170) and at least one compressible bushing (184) between said collar (180) and said locking ring (190) to bias said collar into engagement with said second tube (170) in said second position of said locking ring (190).
Claim 6
Dependent Claim
40 words
A surgical fastener applying apparatus as set forth in claim 3 characterized in that said locking ring (190) has proximally extending teeth (192) for selective reception in notches (40a, 40b) of a main body (30) of said actuator assembly (20).
Claim 7
Dependent Claim
42 words
A surgical fastener applying apparatus as set forth in any one of claimsl to 5 characterized in having a second articulation (110) between said shaft assembly (100) and said fastener applying assembly (200) to permit rotation therebetween about said second axis (112).
Claim 8
Dependent Claim
29 words
A surgical fastener applying apparatus as set forth in claim 6, as dependent on claim 2, characterized in that said second articulation (110) rotatably receives said first articulation (140).
Claim 9
Dependent Claim
49 words
A surgical fastener applying apparatus as set forth in claim 7, as dependent on claim 3, characterized in that said second articulation (110) includes a pinion (116)·and said second tube (170) includes a toothed rack (174) for engaging said pinion in said second position of said locking ring (190).
Claim 10
Dependent Claim
70 words
A surgical fastener applying apparatus as set forth in claim 1 characterized in that said fastener applying assembly (200) includes a fastener holding part (210) and an anvil (290) facing said part (210), and in having a first cable (106) extending between said actuator assembly (20) and said fastener holding part (210) through said shaft assembly (100) for moving said part (210) relative to said anvil to clamp tissue therebetween.
Claim 11
Dependent Claim
79 words
A surgical fastener applying apparatus as set forth in claim 9 characterized in that said fastener holding part (210) includes a pusher actuator (248) for expelling fasteners (212) from said holding part (210) and in having a second cable (108) extending between said actuator assembly (20) and said pusher actuator (248) through said shaft assembly (100) for moving said pusher actuator (248) to expel said fasteners (212) to staple tissue between said anvil (290) and said holding part (210).
