Abstract: Systems, methods, and devices are disclosed for surgical instruments, systems, and methods for detecting skiving of a surgical instrument, such as an instrument used during a robotic or robot-assisted surgery. The embodiments disclosed herein may include one or more sensors adjacent to, coupled to, disposed on, or embedded into an instrument in order to measure deflection thereof during use that may indicate skiving of the instrument. A variety of sensors may be utilized, including strain gauges, resistance-based sensors, fiber optic cables, laser distance measurement units, ultrasonic distance measurement units, optical cable measurement units, etc. In some embodiments, multiple such sensors may be included in an instrument in order to measure magnitude and/or direction of deflection.
