There has been almost no scientific analysis of the dynamics involved concerning the force applied to the scalpel on incision and on the effects extended to the tissue or organ being cut. In order to analyze the dynamics involved on incision, we developed a 2-axis tension-sensing apparatus in order to measure the force on incision in 2 directions. Furthermore, we also developed an apparatus to measure the tension of the thumb and index finger during incision by means of a 2-axis tensionsensing tool. Using the scalpel equipped with a sensor, and the tension measurement device we set out to perform access tension analysis in basic experiments and then later to determine differences in the tension when actually performing incision in head and neck operations to determine the conditions necessary for incision. In the fundamental studies when the scalpel was pushed in and then further pulled, when tension was applied at right angles to the direction cutting, it was found to make an incision in a short time with little dynamic force. In actual otorhinolaryngology operations, it was found that, when cutting the thin tissue behind the ear, force is applied both directly vertically to the scalpel and simultaneously in a horizontal plane as it is pulled but in the thicker tissue of the neck, it is pulled horizontally only after the vertical application of force.
