Abstract
Abstract An apparatus for applying a surgical clip which comprises a staple having a central portion and first and second legs extending from said central portion. A retainer is provided having an opening dimensioned for passage of an end portion of each of said legs when the legs are bent from an open position to a closed position. The apparatus comprises staple forming means in the form of a pair of pivotable members movable from an open position to a closed position when slid into engagement with a camming surface. Staple pusher means engage the central portion of the staple and slides the staple distally into contact with an anvil and with the pivotable members to bend the staple legs to their closed position.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
103 words
In combination: a staple having a pair of legs; a retainer having an opening and adapted to receive said staple legs; and a surgical apparatus for applying said staple to said retainer, said apparatus containing said staple and said retainer therein, said apparatus comprising first and second pivotable arms, means for moving said staple distally towards said retainer, and means for pivoting said arms between an open position and a closed position, so the staple legs contact said arms in said closed position and are thereby bent at an angle to extend inwardly towards each other and enter the opening in the retainer.
Claim 2
Dependent Claim
103 words
In combination: a staple having a pair of legs; a retainer having an opening and adapted to receive said staple legs; and a surgical apparatus for applying said staple to said retainer, said apparatus containing said staple and said retainer therein, said apparatus comprising first and second pivotable arms, means for moving said staple distally towards said retainer, and means for pivoting said arms between an open position and a closed position, so the staple legs contact said arms in said closed position and are thereby bent at an angle to extend inwardly towards each other and enter the opening in the retainer.
Claim 3
Dependent Claim
44 words
A surgical apparatus as recited in claim 1, wherein said pivot means is a pair of opposing stationary camming surfaces for pivoting said arms to the closed position, and the apparatus further comprises means for sliding said arms istally to engage said camming surfaces.
Claim 4
Dependent Claim
23 words
A surgical apparatus as recited in claim 1, further comprising an alignment member connected to said staple pusher means to engage the staple.
Claim 5
Dependent Claim
41 words
A surgical apparatus as recited in claim 1, wherein each said arm has a widened head portion at its proximal end and a narrowed distal portion having a pointed tip, each said head portion mounted to the apparatus by a pin.
Claim 6
Dependent Claim
29 words
A surgical apparatus as recited in claim 1, further comprising a spring member movable from an engaged position to a disengaged position to thereby release said staple moving means.
Claim 7
Dependent Claim
109 words
A surgical apparatus for applying a surgical staple which has a central portion and a pair of spaced apart legs extending from the central portion, said apparatus comprising: a housing having proximal and distal end portions and oppositally disposed raised stationary cam surfaces; a base portion having proximal and distal end portions, said base portion being at least partially slidably disposed between said cam surfaces; and a pair of staple forming members pivotally secured to said base portion distal end, wherein distal movement of the base portion relative to said housing causes said staple forming members to pivot upon contact with a corresponding stationary cam surface of said housing.
Claim 8
Dependent Claim
109 words
A surgical apparatus for applying a surgical staple which has a central portion and a pair of spaced apart legs extending from the central portion, said apparatus comprising: a housing having proximal and distal end portions and oppositally disposed raised stationary cam surfaces; a base portion having proximal and distal end portions, said base portion being at least partially slidably disposed between said cam surfaces; and a pair of staple forming members pivotally secured to said base portion distal end, wherein distal movement of the base portion relative to said housing causes said staple forming members to pivot upon contact with a corresponding stationary cam surface of said housing.
Claim 9
Dependent Claim
26 words
The apparatus according to claim 6, wherein each staple forming member is secured to the distal end of said base portion by a single pivot pin.
Claim 10
Dependent Claim
21 words
The apparatus according to claim 7, wherein the distance between said pivot pins remains constant throughout the operation of the apparatus.
Claim 11
Dependent Claim
19 words
The apparatus according to claim 6, wherein each said staple forming member is spring biased in an open position.
Claim 12
Dependent Claim
39 words
The apparatus according to claim 6, wherein each said staple forming member has a curved exterior surface and the stationary cam surfaces of said housing contact said curved exterior surfaces to cause pivoting motion of said staple forming members.
Claim 13
Dependent Claim
26 words
The apparatus according to claim 6, wherein the housing has a substantially planar base plate and the stationary cam surfaces protrude from the planar base plate.
Claim 14
Dependent Claim
30 words
The apparatus according to claim 11, wherein said base portion is substantially restricted to longitudinal movement relative to said housing as the base portion moves between the stationary cam surfaces.
Claim 15
Dependent Claim
120 words
A surgical apparatus for applying a surgical staple which has a central portion and a pair of spaced apart legs extending from the central portion, said apparatus comprising: a housing having proximal and distal end portions and a longitudinal axis; a base portion having a longitudinal axis and proximal and distal end portions, said base portion being longitudinally slidable within said housing along said housing longitudinal axis; and a pair of staple forming members each pivotally secured by a single pivot pin to said base portion distal end, wherein longitudinal distal movement of the base portion relative to said housing longitudinal axis causes said staple forming members to pivot towards each other upon contact with a portion of said housing.
Claim 16
Dependent Claim
120 words
A surgical apparatus for applying a surgical staple which has a central portion and a pair of spaced apart legs extending from the central portion, said apparatus comprising: a housing having proximal and distal end portions and a longitudinal axis; a base portion having a longitudinal axis and proximal and distal end portions, said base portion being longitudinally slidable within said housing along said housing longitudinal axis; and a pair of staple forming members each pivotally secured by a single pivot pin to said base portion distal end, wherein longitudinal distal movement of the base portion relative to said housing longitudinal axis causes said staple forming members to pivot towards each other upon contact with a portion of said housing.

Claim 20
Dependent Claim
39 words
The apparatus according to claim 13, wherein each said staple forming member has a curved exterior surface and the stationary cam surfaces of said housing contact said curved exterior surfaces to cause pivoting motion of said staple forming members.
