    Abstract: A medical system includes a first electrical circuit, a second electrical circuit electrically isolated from the first electrical circuit, an optical isolator circuit coupled between the first and second electrical circuits, and a common-mode choke comprising a plurality of wires wound around a core and configured to reduce a voltage transient at an input of the optical isolator circuit to a level within a tolerance of the optical isolator circuit. A first end of the wires is conductively coupled to an output of the first electrical circuit and a second end of the wires is conductively coupled to the input of the optical isolator circuit.

    Abstract: A surgical instrument support arm of a teleoperated patient side cart may include a first arm portion including a first connector end and a second a second arm portion including a second connector end. The second arm portion may be removably connectable to the first arm portion via mating engagement of the first and second connector ends. The first and second connector ends may each include complementary mechanical connections and complementary electrical connections. At least one of the electrical connections of the first and second connector ends may include electrical shielding to protect against electrical interference in a position in which the electrical connections are matingly engaged. The electrical shielding may be configured to axially compress when the electrical connections of the first and second connector ends are matingly engaged.

    Abstract: A variety of applications can include apparatus and/or methods that provide an axial force transducer. Two coils wound coaxially with respect to each other can be used with a magnet to determine a distance traveled based on application of an axial force to an instrument component. The two coils and magnet can be configured in a number of ways with respect to the instrument component. In various embodiments, the difference between an inductance associated with one of the two coils along with its relation to the magnet and an inductance associated with the other one of the two coils along with its relation to the magnet can be used to determine the axial force on the component of the instrument associated with the distance travelled. Additional apparatus, systems, and methods are disclosed.

    Abstract: A surgical instrument includes a housing configured to removably attach to a component separate from the surgical instrument, the component comprising a carriage attached to a main frame of a manipulator arm of a surgical system and configured to slidably move along the main frame, the housing comprising a first electrical circuit, and a common-mode choke. When the housing is removably attached to the component, the common-mode choke is coupled between the first electrical circuit and an optical isolator circuit included in the component, and the optical isolator circuit is configured to optically transmit data representative of a signal between the first electrical circuit and a second electrical circuit included in the component.

    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.
