Claim 1
Independent Claim
243 words
A surgical instrument for placing a medical suture about an organic tubular structure comprising a gun portion and a cartridge portion mounted thereon, said cartridge portion comprising a rail assembly including a pair of parallel spaced anvil parts defining anvils with knife guide means extending in between and parallel thereto, medical suture means carried on said rail assembly in sliding relationship therewith and including a plurality of substantially linear wire sutures ejectable therefrom, a pusher cooperating with said linear wire sutures ejectable therefrom, a pusher cooperating with said linear wire sutures, along the longitudinal axis thereof, to eject said linear wire sutures therefrom and to drive same against said anvils to cause said linear wire sutures to wrap about an organic tubular structure held against said anvils, said pusher having a cross section substantially equal to that of said sutures, a knife cooperating with said pusher for severing the tube held against said anvils, said gun including push elements cooperating respectively with said medical suture means and said pusher, means for initially moving said medical suture means and said pusher into proximity with said anvils to hold a tube against said anvils, means for thereafter moving said pusher to eject linear wire sutures from said medical suture means and drive same against said anvils to wrap same about the tube held thereagainst at spaced locations and means for moving said knife to seveR the tube between the wire sutures wrapped about the tube.
Claim 2
Dependent Claim
243 words
A surgical instrument for placing a medical suture about an organic tubular structure comprising a gun portion and a cartridge portion mounted thereon, said cartridge portion comprising a rail assembly including a pair of parallel spaced anvil parts defining anvils with knife guide means extending in between and parallel thereto, medical suture means carried on said rail assembly in sliding relationship therewith and including a plurality of substantially linear wire sutures ejectable therefrom, a pusher cooperating with said linear wire sutures ejectable therefrom, a pusher cooperating with said linear wire sutures, along the longitudinal axis thereof, to eject said linear wire sutures therefrom and to drive same against said anvils to cause said linear wire sutures to wrap about an organic tubular structure held against said anvils, said pusher having a cross section substantially equal to that of said sutures, a knife cooperating with said pusher for severing the tube held against said anvils, said gun including push elements cooperating respectively with said medical suture means and said pusher, means for initially moving said medical suture means and said pusher into proximity with said anvils to hold a tube against said anvils, means for thereafter moving said pusher to eject linear wire sutures from said medical suture means and drive same against said anvils to wrap same about the tube held thereagainst at spaced locations and means for moving said knife to seveR the tube between the wire sutures wrapped about the tube.

Claim 7
Dependent Claim
58 words
A surgical instrument as defined in claim 1, wherein the push elements of said gun comprise a push rod spring biased for retraction into the gun and a sleeve carried on said push rod spring biased for projection out of the gun and a stop means on the push rod to limit the outward travel of said sleeve.
Claim 8
Dependent Claim
57 words
A surgical instrument as defined in claim 1, wherein said medical suture means includes a barrel holder and a pusher guide body in end-to-end abutting relationship and a pair of barrels rotatably position therebetween, each said barrel containing a plurality of said wire sutures, and said pusher including push rods to eject wire sutures from said barrels.
Claim 9
Dependent Claim
16 words
A surgical instrument as defined in claim 7, further including index means for rotating said barrels.
Claim 10
Dependent Claim
33 words
A surgical instrument as defined in claim 8, wherein said index means includes teeth formed on said barrels, a ratchet bar cooperating with said teeth, and cam means for actuating said ratchet bar.

Claim 12
Dependent Claim
22 words
A surgical instrument as defined in claim 8, wherein a wrap encloses said pusher guide body and bears against the shoulder thereon.
Claim 13
Dependent Claim
34 words
