Abstract
A surgical instrument includes a shaft deflection detection system including one or more sensors positioned at a first mechanical junction between a shaft and an actuator coupled with the shaft and/or a second mechanical junction between the shaft and an end effector coupled with the shaft. The shaft is movable relative to the actuator at the first mechanical junction and/or relative to the end effector at the second mechanical junction. The one or more sensors are configured to generate signals indicative of movement of the shaft relative to the actuator and/or the end effector. The movement of the shaft is caused by an external force experienced by the shaft as the shaft of the surgical instrument is maneuvered inside a body of a patient.
