Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 111 words
A surgical instrument for suturing tissue with a double armed suture having a needle attached to each end of the suture comprising: a casing having at least two guide tubes formed therein- the guide tubes each having a cross-sectional diameter sufficient to accept a needle, attached to the suture, when positioned longitudinally within the guide tube; a push rod for each of the guide tubes with each push rod being dimensioned to slidably fit within the guide tube; and means for driving the push rods against the needles when they are positioned within the guide tubes such that the needles are caused to move outwardly and away from the guide tubes.
Claim 2
Dependent Claim 111 words
A surgical instrument for suturing tissue with a double armed suture having a needle attached to each end of the suture comprising: a casing having at least two guide tubes formed therein- the guide tubes each having a cross-sectional diameter sufficient to accept a needle, attached to the suture, when positioned longitudinally within the guide tube; a push rod for each of the guide tubes with each push rod being dimensioned to slidably fit within the guide tube; and means for driving the push rods against the needles when they are positioned within the guide tubes such that the needles are caused to move outwardly and away from the guide tubes.
Claim 3
Dependent Claim 75 words
The surgical instrument according to claim 1 wherein the casing further includes a longitudinal slit for each guide tube which slits extend longitudinally parallel to the guide tubes from a forward end of the casing where the needles are positioned in a rearward direction and wherein each slit pierces through the casing to the respective guide tube and through which slits the suture may be drawn when the needles are positioned within the guide tubes.
Claim 4
Dependent Claim 38 words
The surgical instrument according to claim l'wherein finger grips are mounted to the casing and a thumb ring is mounted with a swivel to the ends of the push rods opposite the ends which push against the needles.
Claim 5
Dependent Claim 98 words
4 . A surgical instrument for use in placing a single mattress stitch using a double armed suture comprising: a casing; at least two guide tubes formed within the casing, each of the guide tubes having a cross-sectional diameter sufficient to accept a needle, attached to the suture, when positioned longitudinally within the guide tube; means for slidably moving the needles in a direction outwardly and away from the guide tubes; and means for permitting the length of suture between the needles to follow the needles when the needles are moved to a position entirely outside the casing.
Claim 6
Dependent Claim 98 words
4 . A surgical instrument for use in placing a single mattress stitch using a double armed suture comprising: a casing; at least two guide tubes formed within the casing, each of the guide tubes having a cross-sectional diameter sufficient to accept a needle, attached to the suture, when positioned longitudinally within the guide tube; means for slidably moving the needles in a direction outwardly and away from the guide tubes; and means for permitting the length of suture between the needles to follow the needles when the needles are moved to a position entirely outside the casing.
