Abstract
Techniques for reducing blade exposures include one or more processors and a drive system configured to be coupled to a cutting instrument. The cutting instrument includes an end effector located at a distal end of the cutting instrument, the end effector comprising opposable gripping jaws and a cutting blade, a shaft configured to be coupled to the drive system, an articulated wrist coupling the end effector to the shaft and one or more drive mechanisms in the shaft for coupling force or torque from the drive system to the end effector and the articulated wrist. The one or more processors are configured to measure a jaw angle between the gripping jaws, measure articulation of the articulated wrist, correct the jaw angle based on the articulation of the articulated wrist, determine a cutting length based on the corrected jaw angle, and perform a cutting operation according to the cutting length.
