Abstract
Abstract Needle holder having an elongate tubular member serving as a shaft and having a bore extending therethrough and having proximal and distal extremities. A push-pull rod is slidably mounted in the bore in the tubular member and has proximal and distal extremities. First and second jaws are carried by the distal extremity of the elongate tubular member. The first jaw is secured to the distal extremity of the tubular member in a fixed position. The second jaw is connected to the push-pull rod to cause the second jaw carried thereby to be moved between a closed needle-clamping position and an open position upon relative movement between said push-pull rod and said tubular member. One of said first and second jaws consists of first and second jaw portions having a slot extending therebetween. The other of said first and second jaws overlies and is disposed in the slot. An actuation device is secured to the tubular member and to the push-pull rod for causing the relative movement between the push-pull rod and the tubular member.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
221 words
In a needle holder for use with a curved surgical needle, an elongate tubular member serving as a shaft having a bore extending therethrough and having proximal and distal extremities, a push-pull rod slidably mounted in the bore in the tubular member and having proximal and distal extremities, first and second jaws carried by the distal extremity of the elongate tubular member, means securing the first jaw to the distal extremity of the tubular member in a fixed position, means connecting said second jaw to said push-pull rod to cause the second jaw carried thereby to be moved between a closed needle-clamping position and an open position upon relative movement between said push-pull rod and said tubular member, one of said first and second jaws consisting of first and second jaw portions having a slot extending therebetween, said first and second jaw portions having arcuate needle-engaging surfaces which in cross-sections conform to the curvature of curved surgical needle, the other of said first and second jaws overlying and being disposed in said slot and having first and second corners in close proximity to the arcuate needle engaging surfaces of the first and second jaw portions and actuation means secured to said tubular member and to said push-pull rod for causing said relative movement between the push-pull rod and the tubular member.
Claim 2
Dependent Claim
221 words
In a needle holder for use with a curved surgical needle, an elongate tubular member serving as a shaft having a bore extending therethrough and having proximal and distal extremities, a push-pull rod slidably mounted in the bore in the tubular member and having proximal and distal extremities, first and second jaws carried by the distal extremity of the elongate tubular member, means securing the first jaw to the distal extremity of the tubular member in a fixed position, means connecting said second jaw to said push-pull rod to cause the second jaw carried thereby to be moved between a closed needle-clamping position and an open position upon relative movement between said push-pull rod and said tubular member, one of said first and second jaws consisting of first and second jaw portions having a slot extending therebetween, said first and second jaw portions having arcuate needle-engaging surfaces which in cross-sections conform to the curvature of curved surgical needle, the other of said first and second jaws overlying and being disposed in said slot and having first and second corners in close proximity to the arcuate needle engaging surfaces of the first and second jaw portions and actuation means secured to said tubular member and to said push-pull rod for causing said relative movement between the push-pull rod and the tubular member.
Claim 3
Dependent Claim
26 words
A needle holder as in claim 1 wherein said first and second jaw portions are provided with sharp corners adapted to engage the curved surgical needle.
Claim 4
Dependent Claim
25 words
A needle holder as in claim 2 wherein said first and second corners are substantially right angle corners adapted to engage the curved surgical needle.
Claim 5
Dependent Claim
18 words
A needle holder as in claim 1 wherein said actuation means is in the form of scissors-type handles.
Claim 6
Dependent Claim
17 words
A needle holder as in claim 1 wherein said jaw portions are secured to said tubular member.
Claim 7
Dependent Claim
19 words
A needle holder as in claim 1 together with hook means carried by the first and second jaw portions.
Claim 8
Dependent Claim
216 words
In a needle holder adapted to be used by the human hand, an elongate tubular member serving as a shaft having a bore extending therethrough and having proximal and distal extremities, a push-pull rod slidably mounted in the bore in the tubular member and having proximal and distal extremities, first and second jaws carried by the distal extremity of the elongate tube member, means securing the first jaw to the distal extremity of the tubular member in a fixed position, a cam member having an elongate slot therein, means securing said second jaw to said cam member, a pivot pin secured to said first jaw and extending through said elongate slot in the cam member, means connecting said cam member to said push-pull rod for causing the cam member to be shifted with respect to said pivot pin to cause the second jaw carried thereby to be moved between a closed needle-clamping position and an open position as said push-pull rod is moved relative to said tubular member by causing rocking movement of said cam member with respect to the pivot pin, and handle means adapted to be grasped by the human hand and secured to said tubular member and said push-pull rod for causing said relative movement between the push-pull rod and the tubular member.
Claim 9
Dependent Claim
216 words
In a needle holder adapted to be used by the human hand, an elongate tubular member serving as a shaft having a bore extending therethrough and having proximal and distal extremities, a push-pull rod slidably mounted in the bore in the tubular member and having proximal and distal extremities, first and second jaws carried by the distal extremity of the elongate tube member, means securing the first jaw to the distal extremity of the tubular member in a fixed position, a cam member having an elongate slot therein, means securing said second jaw to said cam member, a pivot pin secured to said first jaw and extending through said elongate slot in the cam member, means connecting said cam member to said push-pull rod for causing the cam member to be shifted with respect to said pivot pin to cause the second jaw carried thereby to be moved between a closed needle-clamping position and an open position as said push-pull rod is moved relative to said tubular member by causing rocking movement of said cam member with respect to the pivot pin, and handle means adapted to be grasped by the human hand and secured to said tubular member and said push-pull rod for causing said relative movement between the push-pull rod and the tubular member.
