Abstract:
An accelerometer is included within the confined space and limited volume of a distal portion of a surgical instrument. The surgical instrument includes an end component, a joint coupled to the end component, a shaft coupled to the joint, and a force transducer and accelerometer apparatus. The force transducer and accelerometer apparatus is coupled between the joint and the shaft. The force transducer and accelerometer apparatus includes a force sensor and an accelerometer. The accelerometer includes an optic fiber having a Fiber Bragg Grating. Information acquired from the Fiber Bragg Grating is used to drive a vibro-tactile haptic feedback output device coupled to a master control arm surgeon grip.
