Abstract

Abstract An improved combination forceps and cutting instrument. A pair of opposed elongated metal arms are coupled to a first end and have opposing planar forceps-grasping surfaces at a second end. Behind this second end are a pair of opposed cutting blades extending inward from the arms. The cutting blades are perpendicular to the arms and form a scissors type cutting mechanism. The blades are biased towards each other so that the cutting edges scrape each other as the instrument is closed.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 104 words
A forceps and cutting instrument comprising: a pair of opposed, elongated metal arms immovably coupled at a first end and having opposing planar surfaces at a second end for grasping objects therebetween; a pair of opposed cutting blades extending inward from said arms, said blades being rearward of said second end of said arms, each blade having a planar surface perpendicular to one of said arms, said blades being offset so that said blades extend past each other when said arms are closed toward each other; and means for biasing said planar surfaces of said blades toward each other when said arms are closed.
Claim 2
Dependent Claim 104 words
A forceps and cutting instrument comprising: a pair of opposed, elongated metal arms immovably coupled at a first end and having opposing planar surfaces at a second end for grasping objects therebetween; a pair of opposed cutting blades extending inward from said arms, said blades being rearward of said second end of said arms, each blade having a planar surface perpendicular to one of said arms, said blades being offset so that said blades extend past each other when said arms are closed toward each other; and means for biasing said planar surfaces of said blades toward each other when said arms are closed.
Claim 3
Dependent Claim 128 words
A forceps and cutting instrument comprising: a pair of opposed, elongated metal arms coupled at a first end and having opposing planar surfaces at a second end for grasping objects therebetween; a pair of opposed cutting blades extending inward from said arms, said blades being rearward of said second end of said arms, each blade having a planar surface perpendicular to one of said arms, said blades being offset so that said blades extend past each other when said arms are closed toward each other, said blades having aligned slots; and means for biasing said planar surfaces of said blades toward each other when said arms are closed, said biasing means comprising a member extending through said slots, said member having ends which are wider than said slots.
Claim 4
Dependent Claim 128 words
A forceps and cutting instrument comprising: a pair of opposed, elongated metal arms coupled at a first end and having opposing planar surfaces at a second end for grasping objects therebetween; a pair of opposed cutting blades extending inward from said arms, said blades being rearward of said second end of said arms, each blade having a planar surface perpendicular to one of said arms, said blades being offset so that said blades extend past each other when said arms are closed toward each other, said blades having aligned slots; and means for biasing said planar surfaces of said blades toward each other when said arms are closed, said biasing means comprising a member extending through said slots, said member having ends which are wider than said slots.
Claim 5
Dependent Claim 51 words
The instrument of claim 1 wherein said arms are immovably coupled at said first end, each of said arms diverging outwardly for a first portion and extending inwardly from said first portion to said second end, each of said blades being coupled to one of said arms at said second portion.
Claim 6
Dependent Claim 31 words
The instrument of claim 3 wherein each of said blades has an inclined, sharp cutting edge extending rearwardly from proximate said second end of said arm and toward the other arm.
Claim 7
Dependent Claim 74 words
The instrument of claim 4 wherein said blades have aligned slots and said biasing means comprises a member extending through said slots, said member having ends which are wider than said slots, each slot being elongated in a direction substantially perpendicular to said second portion of one of said arms and said slots being curved so that said member moves freely through said slots without binding when said arms are closed towards each other.
Claim 8
Dependent Claim 41 words
The instrument of claim 3 wherein said biasing means comprises a planar member parallel to one of said blades and defining a slot between said planar member and said one of said blades for receiving the other one of said blades.
Claim 9
Dependent Claim 17 words
The instrument of claim 3 wherein at least one of said blades has a serrated cutting edge.
Claim 10
Dependent Claim 26 words
The instrument of claim 3 wherein said opposing planar surfaces at said second ends of said arms and said blades are removably attached to said arms.
Claim 11
Dependent Claim 156 words
A forceps and cutting instrument comprising: a pair of opposed, elongated metal arms immovably coupled at a first end, said arms diverging outwardly for a first portion and extending inwardly at a second portion from said first portion to a second end of said arms; a pair of opposing planar surfaces coupled to said second ends of said arms for grasping objects therebetween; a pair of opposed cutting blades attached to said second portions of said arms, each blade being offset relative to the other so that said blades extend past each other when said arms are closed, said blades having aligned, elongated slots extending in a direction substantially perpendicular to said second portion of said arm, at least one of said blades having a serrated edge extending rearwardly from proximate said second end of said arm and toward the other arm; and a rivet extending through said slots for holding said blades in close proximity.
Claim 12
Dependent Claim 156 words
A forceps and cutting instrument comprising: a pair of opposed, elongated metal arms immovably coupled at a first end, said arms diverging outwardly for a first portion and extending inwardly at a second portion from said first portion to a second end of said arms; a pair of opposing planar surfaces coupled to said second ends of said arms for grasping objects therebetween; a pair of opposed cutting blades attached to said second portions of said arms, each blade being offset relative to the other so that said blades extend past each other when said arms are closed, said blades having aligned, elongated slots extending in a direction substantially perpendicular to said second portion of said arm, at least one of said blades having a serrated edge extending rearwardly from proximate said second end of said arm and toward the other arm; and a rivet extending through said slots for holding said blades in close proximity.
