Abstract
A knife having a blade tip configuration that reduces incisional force by providing a more efficient distribution of tissue piercing and cutting forces over the cutting edges. The distal tip of the blade has a profile in plan view that may be described as bounded by the following equations w=5.886(d)and w=1.561(d)where w is the distance in microns from the blade's longitudinal axis to the blade's cutting edge and d is the distance in microns along the blade's longitudinal axis from the extreme distal point of the blade tip. The extreme distal point of the tip has a slightly rounded, rather than pointed, profile, with a tip radius of approximately 40 microns or less.
