In Situ Measurements of Cutting Forces During Surgery

Several experiments were completed in conjunction with a surgical doctor to acquire force data during cutting surgical acts for analysis. The force-position relationship, the frequency components present in the signal and the significance of the cutting rate, as well as any invariant properties are investigated. A database of the collected data has been created and preliminary analysis performed. (Figure 6.2)
