Abstract
Abstract A device for manipulating a surgical needle which has been set in tissue is provided which comprises a tube with a telescoping rod therein, the tube and rod having a diametrical slot in one end forming a bifurcated slot. The tube and rod are relatively rotatable resulting in the slot portions being movable in and out of alignment. When the slot portions are in alignment the shank of the needle can be received in the slots, and as they are moved out of alignment, the needle is grasped by the side walls of the slots. Diametrical holes in the tube and rod are also provided forming a bifurcated passage for gripping the tip of the needle in a similar manner.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
114 words
A device for manipulating a surgical needle, comprising: a hollow tube having knurled flange at one end and a pair of diametrically opposed slots at an opposite end, a rod member sized to telescopically fit within said hollow tube having a knurled flange at one end and a flat face with a diametrical slot formed therein at an opposite end, said rod member rotatable within said tube to permit alignment and misalignment between said slots in said tube and said slot in said rod member, whereby, said slots, upon alignment, can receive the shank of said surgical needle, and upon relative rotation of said rod member, said device will grip said needle for manipulation.
Claim 2
Independent Claim
114 words
A device for manipulating a surgical needle, comprising: a hollow tube having knurled flange at one end and a pair of diametrically opposed slots at an opposite end, a rod member sized to telescopically fit within said hollow tube having a knurled flange at one end and a flat face with a diametrical slot formed therein at an opposite end, said rod member rotatable within said tube to permit alignment and misalignment between said slots in said tube and said slot in said rod member, whereby, said slots, upon alignment, can receive the shank of said surgical needle, and upon relative rotation of said rod member, said device will grip said needle for manipulation.
Claim 3
Dependent Claim
62 words
The device of claim 1 including a pair of diametrically opposed holes through said tube and a diametrical hole through said rod member which can be aligned with said holes in said tube, whereby, said holes, upon alignment, can receive the tip of said surgical needle, and upon relative rotation of said rod member, said device will grip said needle for manipulation.
Claim 4
Dependent Claim
26 words
The device of claim 1 wherein said knurled flanges have alignment markings thereon to assist in the alignment of said slots when viewing said knurled ends.
Claim 5
Dependent Claim
26 words
The device of claim 2 wherein said knurled flanges have alignment markings thereon to assist in the alignment of said holes when viewing said knurled ends.
Claim 6
Dependent Claim
74 words
A surgical needle manipulator comprising: a bifurcated slot having two slot portions relatively rotatable for grasping the shank of a surgical needle which has been set into tissue, means for directing said needle through said tissue until the tip of said needle is exposed, means for releasing said shank of said needle, means for grasping said tip of said needle to pull said needle entirely through said tissue, means for releasing said needle tip.
Claim 7
Dependent Claim
74 words
A surgical needle manipulator comprising: a bifurcated slot having two slot portions relatively rotatable for grasping the shank of a surgical needle which has been set into tissue, means for directing said needle through said tissue until the tip of said needle is exposed, means for releasing said shank of said needle, means for grasping said tip of said needle to pull said needle entirely through said tissue, means for releasing said needle tip.
Claim 8
Dependent Claim
26 words
A surgical needle manipulator according to claim 5 wherein said means for grasping said needle tip comprises a bifurcated passage having two passage portions relatively rotatable.
Claim 9
Dependent Claim
93 words
A surgical needle manipulator comprising: means for grasping the shank of a surgical needle which has been set into tissue, which further comprises a bifurcated slot having two slot portions relatively rotatable, side walls of said slot portions forming gripping areas upon relative rotation of said portions, means for directing said needle through said tissue until the tip of said needle is exposed, means for releasing said shank of said needle, means for grasping said tip of said needle to pull said needle entirely through said tissue, means for releasing said needle tip.
Claim 10
Dependent Claim
93 words
A surgical needle manipulator comprising: means for grasping the shank of a surgical needle which has been set into tissue, which further comprises a bifurcated slot having two slot portions relatively rotatable, side walls of said slot portions forming gripping areas upon relative rotation of said portions, means for directing said needle through said tissue until the tip of said needle is exposed, means for releasing said shank of said needle, means for grasping said tip of said needle to pull said needle entirely through said tissue, means for releasing said needle tip.
Claim 11
Dependent Claim
106 words
A surgical needle manipulator comprising: means for grasping the shank of a surgical needle which has been set into tissue, means for directing said needle through said tissue until the tip of said needle is exposed, means for releasing said shank of said needle, means for grasping said tip of said needle to pull said needle entirely through said tissue, which further comprises two members, each with a hole therethrough forming a bifurcated passage having two passage portions relatively rotatable in and out of alignment, side walls of said passage portions forming gripping areas upon relative rotation of said portions, means for releasing said needle tip.
Claim 12
Dependent Claim
106 words
A surgical needle manipulator comprising: means for grasping the shank of a surgical needle which has been set into tissue, means for directing said needle through said tissue until the tip of said needle is exposed, means for releasing said shank of said needle, means for grasping said tip of said needle to pull said needle entirely through said tissue, which further comprises two members, each with a hole therethrough forming a bifurcated passage having two passage portions relatively rotatable in and out of alignment, side walls of said passage portions forming gripping areas upon relative rotation of said portions, means for releasing said needle tip.
Claim 13
Independent Claim
116 words
A system for pulling a surgical needle through tissue into which it has been set in a location of limited accessibility comprising: a cannula positioned with a first end adjacent said location of limited accessibility and with a second end exposed to an area of accessibility, a needle manipulator insertable through said second end of said cannula and having means for securely grasping the shank of said set needle, means for directing said needle through said tissue until the tip of said needle is exposed, means for releasing said shank of said needle, means for grasping said tip of said needle to pull said needle entirely through said tissue, and means for releasing said needle tip.
