Abstract

A gyroscopic stabilizer configured to stabilize a surgical instrument relative to a patient includes a frame having a central axis and a hub configured to releasably couple with the surgical instrument. A first gyroscope assembly is coupled with a first frame portion and a second gyroscope assembly is coupled with a second frame portion. Each gyroscope assembly includes a gimbal pivotably coupled with the respective frame portion about a precession axis, a motor, and a rotor rotatably coupled with the motor about a spin axis perpendicular to the respective precession axis. Each gyroscope assembly is operable generate a torque in a torque plane that contains the respective spin axis and the respective precession axis. The torques are configured to resist rotation of the gyroscopic stabilizer relative to the patient about respective device axes that are perpendicular to the central axis and to one another.
