Abstract
Abstract In apparatus for applying a plurality of surgical fasteners to body tissue (22) clamped between fastner holding (50) and anvil (52) parts of the apparatus, tissue edge control members (68,74) extend into at least one end. and preferably both ends, of the fastener array to prevent any portion of the tissue from extending beyond the ends of the array. This ensures that the fastener array extends completely across the tissue and that no portion of the tissue remains unfastened.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
146 words
Apparatus for applying to body tissue (22) a linear array of surgical fasteners (64) held ready for application in a holder (50), the apparatus comprising the holder (50), an anvil (52) opposite the holder and spaced apart from the holder to permit accommodation of the tissue (22) between the anvil and the holder, and a pusher (60) for expelling the array of fasteners outwardly from the holder towards the anvil thereby to apply the fasteners to the tissue, the apparatus further comprising a tissue edge control member (68,74: 80,82:90,92) at one end at least of the linear array of fasteners (64), said tissue edge control member being in longitudinal alignment with and overlapping or extending into the respective end of the fastener array, thereby preventing tissue (22) to be fastened by the array of fasteners from extending beyond said one end at least of the array.
Claim 2
Dependent Claim
47 words
Apparatus as claimed in claim 1, characterized in that the space between the holder and the anvil has opposed open and closed ends, with a first said tissue edge control member at the closed end and a second said tissue edge control member at the open end.
Claim 3
Dependent Claim
17 words
Apparatus as claimed in claim 2 characterized in that the first control member is a fixed web.
Claim 4
Dependent Claim
47 words
Apparatus as claimed in claim 2 or 3, characterized in that the second control member is housed in the holder and is movable between a retracted position within the holder and a controlling position in which it extends from the holder across the space to the anvil.
Claim 5
Dependent Claim
22 words
Apparatus as claimed in claim 4 including a recess in the anvil to receive the second control member in its controlling position.
Claim 6
Dependent Claim
34 words
Apparatus as claimed in claim 4 or 5 characterized in that the holder applies to the second control member the force required to move the control member from the retracted to the controlling position.
Claim 7
Dependent Claim
53 words
Apparatus as claimed in any one of the preceding claims characterized in that the tissue edge control member, or at least one of the tissue edge control members, has a line of action which lies closer to the mid-point of the array of fasteners than the adjacent end of the line of fasteners.
Claim 8
Dependent Claim
37 words
Apparatus as claimed in claim 7 characterized in that the array of fasteners is arranged as at least three parallel rows of fasteners, that is, a pair of outer fastener rows and at least one inner row.
Claim 9
Dependent Claim
46 words
Apparatus as claimed in claim 8 characterized in that at least one of the two outer rows extends beyond the end of the or each inner row and the line of action of the control member is at the end of the or each inner row.
Claim 10
Dependent Claim
56 words
Apparatus as claimed in claim 8 characterized in that the outer rows terminate short of the end of the inner row, or at least one of the inner rows, and the control member has two limbs which lies one to each side of the long inner row(s) at the end of each of the outer rows.
Claim 11
Independent Claim
25 words
An apparatus as claimed in any one of the preceding claims wherein said control member (90,92) is U-shaped with a pair of legs facing inwardly.
Claim 12
Dependent Claim
122 words
A cartridge comprising a holder for holding a linear array of surgical fasteners (64) ready for application, and an anvil (52) opposite the holder and spaced apart from the holder to permit accommodation between the anvil and the holder of the bodily tissue to be fastened by expulsion of the fasteners from the holder towards the anvil through the action of a pusher on the fasteners in the holder, the cartridge being characterized by a tissue edge control member (68,74 : 80,82 : 90,92) in longitudinal alignment with, and at one end at least of, the linear array of fasteners, to prevent tissue to be fastened by the array of fasteners from extending beyond said one end at least of the array.
Claim 13
Dependent Claim
47 words
A cartridge as claimed in claim 12 characterized in that the space between the holder and the anvil has opposed open and closed ends, a first said tissue edge control member at the closed end and a second said tissue edge control member at the open end.
Claim 14
Dependent Claim
38 words
A cartridge as claimed in claim 12 or 13, characterized in that the array of fasteners comprises at least three parallel lines of fasteners, namely, a pair of outer lines of fasteners and at least one inner line.
Claim 15
Dependent Claim
64 words
A cartridge as claimed in claim 14, characterized in that the tissue edge control member has a line of action at an end of the inner line or lines of fasteners, and at least one of the outer lines of fasteners extends beyond the said end of the or each inner line of fasteners and beyond said line of action of the control member.
Claim 16
Dependent Claim
80 words
A cartridge as claimed in claim 14, characterized in that the control member has two limbs, each with a line of action at the end of a different one of the lines forming the outer line of fasteners, and further characterized in that at least one end of the inner line or lines of fasteners extends beyond both the corresponding ends of the outer lines of fasteners and the said lines of action of the limbs of the control member.
