摘要：
A surgical instrument that includes a housing linkable with a manipulator arm of a robotic surgical system, a shaft coupled to the housing, a force transducer on a distal end of the shaft, and a plurality of fiber optic strain gauges on the force transducer is disclosed. The plurality of strain gauges are coupled to a fiber optic splitter or an arrayed waveguide grating (AWG) multiplexer, which can be coupled to a fiber optic connector. A wrist joint coupled to an end effector is coupled to a distal end of the force transducer. A robotic surgical manipulator that includes a base link coupled to a distal end of a manipulator positioning system, and a distal link with an instrument interface, and a fiber optic connector optically linkable to a surgical instrument. A method of passing data between an instrument and a manipulator via optical connectors is also provided.
