Abstract
Abstract A surgical scissors for excising tissue in areas of limited access where straight scissors cannot reach. The scissors has a hook-shaped end with cutting blades on a cutting axis which is generally perpendicular to the axis along which handle members of the scissors extend. The hook-shaped end may carry a second pair of cutting blades in a cutting plane which is generally parallel to the axis along which the handle members extend.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
54 words
A pair of surgical scissors comprising two handle members extending along a first axis and each having a hook-shaped end carrying a cutting edge, and two aligned pivots pivotally connecting the hook-shaped ends, the cutting edges cooperating to form two blades for cutting in a plane which is generally perpendicular to the first axis.
Claim 2
Dependent Claim
54 words
A pair of surgical scissors comprising two handle members extending along a first axis and each having a hook-shaped end carrying a cutting edge, and two aligned pivots pivotally connecting the hook-shaped ends, the cutting edges cooperating to form two blades for cutting in a plane which is generally perpendicular to the first axis.
Claim 3
Dependent Claim
85 words
A pair of surgical scissors comprising two handle members extending along a first axis and each having a hook-shaped end carrying two cutting edges, and two aligned pivots pivotally connecting the hook-shaped ends, the cutting edges cooperating to form first cutting blades for cutting in a plane generally perpendicular to the first axis and second cutting blades in a cutting plane which is generally parallel to the first axis, the aligned pivots extending along an axis which is between the first and second cutting blades.
Claim 4
Dependent Claim
85 words
A pair of surgical scissors comprising two handle members extending along a first axis and each having a hook-shaped end carrying two cutting edges, and two aligned pivots pivotally connecting the hook-shaped ends, the cutting edges cooperating to form first cutting blades for cutting in a plane generally perpendicular to the first axis and second cutting blades in a cutting plane which is generally parallel to the first axis, the aligned pivots extending along an axis which is between the first and second cutting blades.
Claim 5
Dependent Claim
84 words
A pair of surgical scissors comprising two handle members which are joined at a first pivot and extend along a first axis, each having a hook-shaped end, the bent portions of the hook-shaped ends having blade edges which cooperate to cut in a plane generally perpendicular to the first axis, and said hook-shaped ends also having blades which are joined at a second pivot aligned with said first pivot and which blades form reverse-acting scissors extending rearward past the axis of said second pivot.
Claim 6
Dependent Claim
84 words
A pair of surgical scissors comprising two handle members which are joined at a first pivot and extend along a first axis, each having a hook-shaped end, the bent portions of the hook-shaped ends having blade edges which cooperate to cut in a plane generally perpendicular to the first axis, and said hook-shaped ends also having blades which are joined at a second pivot aligned with said first pivot and which blades form reverse-acting scissors extending rearward past the axis of said second pivot.
