Abstract:
A surgical instrument includes a force sensor apparatus that is immune to noise from arcing cautery without relying on fiber optic strain gauges, and that is autoclabable. The surgical instrument includes a housing, a shaft, the force sensor apparatus, a joint, and an end component. The force sensor apparatus includes at least one strain gauge that is enclosed in a Faraday cage. The Faraday cage includes a sensor capsule that includes one or more strain gauges, a cable shield tube connected to the sensor capsule, and an electronics enclosure connected to the cable shield tube. The sensor capsule is positioned between the joint and the shaft. The cable shield tube extends through the shaft to the electronics enclosure that is within the housing.
