Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
A surgical stapler (10) having initiating means (40) slidable between a retracted position and an extended position to activate driving means (12) to drive staples into tissue, characterised in that said initiating means is operatively linked to camming means (74) such that movement of the initiating means towards the retracted position causes said camming means to move to an inoperative position against biasing means, whereby said initiating means are biased towards the extended position by said biasing means.
Claim 2
Dependent Claim
41 words
A stapler according to claim 1, wherein said camming means (74) is pivotally mounted and includes a surface located between the pivotal mounting (78) of said camming means and said biasing means (72) adapted to bear against said driving means (12).
Claim 3
Dependent Claim
24 words
A stapler according to claim 1 or claim 2 including first detent means (5) to retain said initiating means (40) in its retracted position.
Claim 4
Dependent Claim
32 words
A stapler according to any one of claims 1 to 3 wherein said biasing means (72) includes a spring acting between said camming means (74) and the body (20) of said stapler.
Claim 5
Dependent Claim
50 words
The surgical stapler of claim 2, said initiating means (40) comprising handle means (42) connected to said driving means, said handle means terminating in a dowel (54) insertable in a groove (76) in said camming means (74) to be held within said groove pending disengagement of said first detent means.
Claim 6
Dependent Claim
49 words
The surgical stapler of claim 1 wherein said stapler comprises a first jaw (22) attached to a second jaw (24) to fit around said tissue, and further comprises overriding means (80) capable of holding said camming means (74) in place until said jaws are properly attached to each other.
Claim 7
Dependent Claim
75 words
The surgical stapler of claim 6 wherein said first jaw (22) is attached to said second jaw (24) by means of a clamp actuating a lever (60) on said first jaw, said overriding means (80) comprising second detent means spring-loaded and insertable into said driving means (12), said second detent means pivotable out of said driving means by contact with a peg (90) located on said lever upon closing of said first and second jaws.
Claim 8
Dependent Claim
67 words
The surgical stapler of claim 7 wherein said second detent means includes a hooking bar (86) spring-loaded and pivotable into a mating groove (88) on said driving means (12), said hooking bar holding said driving means within said stapler, until said peg pivots said hooking bar out of said mating groove upon the proper clamping of said first jaw to said second jaw (24) of said stapler.
