Abstract

The invention is directed to a pair of laparoscopic scissors, comprising a pair of blades connected at a pivot, where the cutting edge forms an angle with the outer surface along the length of the blade such that tension during a cutting operation at the tip portion is about the same as tension at the body portion during the cutting operation. In one aspect of the invention, the angle formed is continuously changing over the length of the blade. In another aspect, the angle at the tip portion is greater than at the body portion, and the angle progressively decreases from the tip portion to the body portion. In yet another aspect, the blade may comprise a proximal portion proximal to the body portion having a third body thickness, where the second body thickness is thicker than the first and third body thicknesses.
