Patent ID: 8114107

Claim:
A laparoscopic scissor comprising: an actuator; and a shaft connected to the actuator and having a first and a second scissor blade extending from the shaft, the first scissor blade having a first non-planar blade surface, a first non-planar opposing surface opposite the first non-planar blade surface, the first non-planar blade surface and the first non-planar opposing surface defining one of a first parabolic, cubic and quadratic cutting edge extending between the first non-planar blade surface and the first non-planar opposing surface and the second scissor blade having a second non-planar blade surface, a second non-planar opposing surface opposite the second non-planar blade surface, the second non-planar blade surface and the second non-planar opposing surface defining one of a second parabolic, cubic and quadratic cutting edge extending between the second non-planar blade surface and the second non-planar opposing surface.
