Abstract
Abstract An apparatus for applying a relatively large number of surgical fasteners to body tissue, application of some fasteners is made to precede application of other fasteners in order to spread out and thereby reduce the peak fastener applying load or force.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
145 words
Apparatus for applying a longitudinal array of surgical fasteners to body tissue comprising: a plurality of surgical fasteners in a longitudinal array; fastener pusher means for pushing the fasteners into the tissue along an axis transverse to the longitudinal array, the fastener pusher means including a first rigid longitudinal member parallel to and coextensive with the longitudinal array; a second member for supplying the work required for pushing the fasteners into the tissue; and first means for transmitting the work supplied by the second member to the first member so that one end of the first member initially moves parallel to the transverse axis substantially faster than the other end of the first member to cause the fasteners adjacent said one end of the first member to be applied to the tissue in advance of the fasteners adjacent said other end of the first member.
Claim 2
Dependent Claim
145 words
Apparatus for applying a longitudinal array of surgical fasteners to body tissue comprising: a plurality of surgical fasteners in a longitudinal array; fastener pusher means for pushing the fasteners into the tissue along an axis transverse to the longitudinal array, the fastener pusher means including a first rigid longitudinal member parallel to and coextensive with the longitudinal array; a second member for supplying the work required for pushing the fasteners into the tissue; and first means for transmitting the work supplied by the second member to the first member so that one end of the first member initially moves parallel to the transverse axis substantially faster than the other end of the first member to cause the fasteners adjacent said one end of the first member to be applied to the tissue in advance of the fasteners adjacent said other end of the first member.
Claim 3
Dependent Claim
37 words
The apparatus defined in claim 1 wherein the first means includes second means for increasing the rate of motion of said other end of the first member parallel to the transverse axis as the fasteners are applied.
Claim 4
Dependent Claim
48 words
The apparatus defined in claim 2 wherein the first and second means cooperate so that both ends of the first member have moved substantially the same distance parallel to the transverse axis when all the work supplied by the second member has been transmitted to the first member.
Claim 5
Dependent Claim
34 words
The apparatus defined in claim 1 wherein the second member supplies the work required for pushing the fasteners into the tissue by moving with a component of motion substantially parallel to the longitudinal array.
Claim 6
Dependent Claim
133 words
The apparatus defined in claim 4 further comprising: a third member; and third means for mounting the first member relative to the third member so that the first member can only move relative to the third member substantially parallel to the transverse axis, the second member being in sliding contact with the first member substantially parallel to the longitudinal array; the first means further including first and second cam and cam follower assemblies connected between the second and third members and respectively located adjacent said one and said other end of the first member for causing the second member to move relative to the third member with a component of motion substantially parallel to the transverse axis as the second member moves relative to the third member substantially parallel to the longitudinal array.
Claim 7
Dependent Claim
49 words
The apparatus defined in claim 5 wherein the initial portion of the cam surface traversed by the cam follower of the first cam and cam follower assembly is more nearly parallel to the transverse axis than the corresponding cam surface portion of the second cam and cam follower assembly.
Claim 8
Dependent Claim
52 words
The apparatus defined in claim 6 wherein after the initial cam surface portion of the first cam and cam follower assembly, there is a portion of said cam surface which is more nearly parallel to the longitudinal array than the corresponding cam surface portion of the second cam and cam follower assembly.
