Abstract
Abstract A multiple fire surgical stapler comprises an elongate frame and a pair of jaws movably secured to one another at a proximal end and to the frame at a distal end thereof. Each of the jaws includes a plurality of segments movably secured to one another, whereby the jaws can alternately assume different configurations. A plurality of staples is mounted to one of the jaws, while a firing mechanism is operatively connected to the frame for firing the staples to close the staples.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
79 words
A multiple fire surgical stapler comprising: an elongate frame; a pair of jaws movably secured to one another at a proximal end and to said frame at a distal end thereof, each of said jaws including a plurality of segments movably secured to one another, whereby said jaws can alternately assume different configurations; a plurality of staples mounted to one of said jaws; and firing means operatively connected to said frame for firing said staples to close said staples.
Claim 2
Dependent Claim
79 words
A multiple fire surgical stapler comprising: an elongate frame; a pair of jaws movably secured to one another at a proximal end and to said frame at a distal end thereof, each of said jaws including a plurality of segments movably secured to one another, whereby said jaws can alternately assume different configurations; a plurality of staples mounted to one of said jaws; and firing means operatively connected to said frame for firing said staples to close said staples.
Claim 3
Dependent Claim
21 words
The stapler defined in claim 1, further comprising means for stiffening said jaws prior to an actuation of said firing means.
Claim 4
Dependent Claim
20 words
The stapler defined in claim 2 wherein said means for stiffening serves to rigidify said jaws in a predetermined configuration.
Claim 5
Dependent Claim
12 words
The stapler defined in claim 3 wherein said predetermined configuration is linear.
Claim 6
Dependent Claim
24 words
The stapler defined in claim 1 wherein said segments are provided with mating projections and recesses, the projections being slidably inserted into corresponding recesses.
Claim 7
Dependent Claim
17 words
The stapler defined in claim 1 wherein said staples are arrayed in a plurality of parallel rows.
Claim 8
Dependent Claim
35 words
The stapler defined in claim 1, further comprising severing means disposed in part between a pair of said rows for severing tissues stapled between the rows of said pair upon actuation of said firing means.
Claim 9
Dependent Claim
40 words
The stapler defined in claim 1 wherein said frame is flexible and has a diameter smaller than a biopsy channel of an endoscope, whereby the stapler may be used in conjunction with the endoscope to perform an endoscopic surgical operation.
Claim 10
Dependent Claim
95 words
A multiple fire surgical stapler comprising: an elongate frame; a pair of jaws movably secured to one another at a proximal end and to said frame at a distal end thereof; a plurality of staples mounted to one of said jaws; means on said jaws for enabling a bending of said jaws during an endoscopic insertion procedure; firing means operatively connected to said frame for firing said staples to close said staples; and means operatively connected to said frame and to said jaws for stiffening said jaws prior to an actuation of said firing means.
Claim 11
Dependent Claim
95 words
A multiple fire surgical stapler comprising: an elongate frame; a pair of jaws movably secured to one another at a proximal end and to said frame at a distal end thereof; a plurality of staples mounted to one of said jaws; means on said jaws for enabling a bending of said jaws during an endoscopic insertion procedure; firing means operatively connected to said frame for firing said staples to close said staples; and means operatively connected to said frame and to said jaws for stiffening said jaws prior to an actuation of said firing means.
Claim 12
Dependent Claim
20 words
The stapler defined in claim 9 wherein said means for stiffening serves to rigidify said jaws in a predetermined configuration.
Claim 13
Dependent Claim
12 words
The stapler defined in claim 10 wherein said predetermined configuration is linear.
Claim 14
Dependent Claim
41 words
The stapler defined in claim 9 wherein each of said jaws includes a plurality of segments movably secured to one another, said means for enabling including mating projections and recesses on said segments, the projections being slidably inserted into corresponding recesses.
Claim 15
Dependent Claim
17 words
The stapler defined in claim 9 wherein said staples are arrayed in a plurality of parallel rows.
Claim 16
Dependent Claim
35 words
The stapler defined in claim 9, further comprising severing means disposed in part between a pair of said rows for severing tissues stapled between the rows of said pair upon actuation of said firing means.
Claim 17
Dependent Claim
40 words
The stapler defined in claim 9 wherein said frame is flexible and has a diameter smaller than a biopsy channel of an endoscope, whereby the stapler may be used in conjunction with the endoscope to perform an endoscopic surgical operation.
Claim 18
Independent Claim
104 words
A method for use in a surgical procedure, comprising the steps of: providing a pair of jaws movably secured to one another at a proximal end; bending said jaws along their respective lengths; rigidifying said jaws so that each assumes a predetermined configuration; disposing said jaws about internal body tissues of a patient; firing a plurality of staples from one of said jaws through the surrounded internal body tissues and against the other of said jaws; and closing said staples so that said staples are arrayed in said internal body tissues in the predetermined configuration assumed by said jaws during said step of rigidifying.
Claim 19
Independent Claim
104 words
A method for use in a surgical procedure, comprising the steps of: providing a pair of jaws movably secured to one another at a proximal end; bending said jaws along their respective lengths; rigidifying said jaws so that each assumes a predetermined configuration; disposing said jaws about internal body tissues of a patient; firing a plurality of staples from one of said jaws through the surrounded internal body tissues and against the other of said jaws; and closing said staples so that said staples are arrayed in said internal body tissues in the predetermined configuration assumed by said jaws during said step of rigidifying.
Claim 20
Dependent Claim
46 words
The method defined in claim 16 wherein said jaws each includes a plurality of segments movably secured to one another, said step of bending including the step of pivoting said segments relative to each other, whereby each of said jaws assumes different configurations at different times.
Claim 21
Dependent Claim
12 words
The stapler defined in claim 16 wherein said predetermined configuration is linear.
Claim 22
Dependent Claim
17 words
The stapler defined in claim 16 wherein said staples are arrayed in a plurality of parallel rows.
Claim 23
Dependent Claim
