Abstract
Sharpness of surgical blades is an important parameter in cutting human tissues and
skins. It has a critical effect on the quality of cutting (scarring, pain, sharps injury and
infection transmission issues), the required energy to do the cutting, the surgery
operation time and the protection for medical officers. Presently, there is no standard
or protocol available to quantify the blade penetration and sharpness. In this work, a
customized cutting test machine is designed and developed for the purpose of
measuring the cutting force of surgical blade. A specific system of cutting with the
test parameters (the thickness of PE foil test material, the tip geometry and the tip
surface roughness) is created to represent the real surgical blade application. The
ultimate aim is to study the relationship of these parameters for the measurement of
the penetration and cutting force, thus estimating the cutting force of a surgical blade.
From the experiments carried out, it can be concluded that the tip geometry and the tip
surface roughness of the surgical blade do have effect on the sharpness performance
of the surgical blade.
