Abstract
Abstract In a surgical fastener applying instrument of the type in which the tissue is first clamped by operation of a lever mechanism, a releasable latch is included in the lever mechanism for releasably holding the tissue clamping elements at an intermediate latching position. In this position, the tissue to be fastened is enclosed but not fully clamped by the instrument so that the position of the instrument relative to the tissue can be adjusted without reopening the instrument.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
122 words
Apparatus for applying surgical fasteners to body tissue comprising: an anvil assembly (18), a fastener holding assembly (20) movably mounted relative to the anvil assembly (18); and actuator means (70) for moving the fastener holding assembly (20) toward the anvil assembly (18) to clamp the tissue to be fastened between the anvil assembly (18) and the fastener holding assembly (20), the actuator means (70) including detent means for releasably holding the fastener holding assembly (20) at a predetermined position intermediate the position in which the actuator means (70) begins to move the fastener holding assembly (20) toward the anvil assembly (18) and the position in which the tissue is fully clamped between the fastener holding assembly (20) and the anvil assembly (18).
Claim 2
Dependent Claim
122 words
Apparatus for applying surgical fasteners to body tissue comprising: an anvil assembly (18), a fastener holding assembly (20) movably mounted relative to the anvil assembly (18); and actuator means (70) for moving the fastener holding assembly (20) toward the anvil assembly (18) to clamp the tissue to be fastened between the anvil assembly (18) and the fastener holding assembly (20), the actuator means (70) including detent means for releasably holding the fastener holding assembly (20) at a predetermined position intermediate the position in which the actuator means (70) begins to move the fastener holding assembly (20) toward the anvil assembly (18) and the position in which the tissue is fully clamped between the fastener holding assembly (20) and the anvil assembly (18).
Claim 3
Dependent Claim
33 words
The apparatus defined in claim 1 wherein the actuator means (70) further includes a pivotal actuator member (72), and wherein the detent means releasably holds the actuator member (72) at a predetermined position.
Claim 4
Dependent Claim
41 words
The apparatus defined in claim 2 wherein in the actuator means (70) further includes a pusher member (52) which is operatively connected to the fastener holding assembly (20) and which translates linearly in response to pivoting of the actuator member (72).
Claim 5
Dependent Claim
43 words
The apparatus defined in claim 3 wherein the actuator member (72) includes a cam surface portion (80a, 80b, 80c) and the pusher member (52) includes a cam follower surface portion (62a, 62b, 62c) in contact with the cam surface portion (80a, 80b, 80c).
Claim 6
Dependent Claim
23 words
The apparatus defined in claim 4 wherein the detent means comprises cooperating segments (80b, 62b) of the cam and cam follower surface portions.
Claim 7
Dependent Claim
48 words
The apparatus defined in claim 2 wherein the anvil assembly (18) and the fastener holding assembly (20) are both longitudinal, and wherein the longitudinal axes of the anvil assembly (18) and the fastener holding assembly (20) are coplanar at all times during operation of the actuator means (70).
Claim 8
Dependent Claim
91 words
The apparatus defined in claim 6 wherein the fastener holding assembly (20) is pivotally mounted adjacent one end of each of the fastener holding and anvil assemblies (20, 18), and wherein the fastener holding assembly (20) includes means (30) adjacent the end of the fastener holding assembly remote from the pivotal mounting (24, 26) for contacting the anvil assembly (18) adjacent the end of the anvil assembly remote from the pivotal mounting (24, 26) when the fastener holding assembly (20) has pivoted toward the anvil assembly (18) to a predetermined degree.
Claim 9
Dependent Claim
27 words
The apparatus defined in claim 7 wherein the detent means becomes operative after the means (30) for contacting the anvil assembly (18) has contacted the anvil assembly.
