Abstract: An integrated circuit includes a nexus and a first, a second, a third, and a fourth circuit board. Each of the first and second circuit boards is coupled to opposing sides of the nexus, and each of the third and fourth circuit boards is coupled to opposing sides of the second circuit board. The integrated circuit is transitionable between a first, open configuration, in which the first, second, third and fourth circuit boards and the nexus are substantially coplanar, and a second configuration, in which the first, second, third and fourth circuit boards and the nexus are coupled to one another to define a cavity therein.

Abstract: A method of calibrating a torque sensor for a motor with a controller includes determining a gain of the torque sensor, zeroing a torque reading of the torque sensor, accelerating the motor at a known rate, and determining an inertia of the motor in response to accelerating the motor. Zeroing the torque reading occurs when the motor is in an unloaded and unactivated condition and accelerating the motor occurs when the motor is in an unloaded condition.

Abstract: A torque transducer for mounting a motor includes a mounting flange, a motor flange, a body, and a strain gauge. The mounting flange is configured to secure the torque transducer to a fixed structure. The motor flange is configured to secure to a motor. The body interconnects the mounting and motor flanges. The body defines a channel about a longitudinal axis of the body and is configured to flex in response to the mounting flange and the motor flange rotating relative to one another in response to torque of the motor. The strain gauge is positioned on the body to measure flexation of the body.

Abstract: The present disclosure is directed to an electromechanical surgical system having an end effector and an adapter assembly for selectively interconnecting the end effector and a hand-held surgical instrument. A one-wire bidirectional serial communications interface or bus extends through the end effector, the adapter assembly, and the hand-held surgical instrument. The hand-held surgical instrument includes a master circuit coupled to the bus and configured to identify or control the adapter assembly or the end effector. A power source is couplable to the bus and configured to provide power to the adapter assembly or the end effector. A first switch connects the master circuit to the bus and a second switch connects the power source to the bus. A processor controls operation of the hand-held surgical instrument. The controller has a wake-up pin connected to the bus and is configured to receive a presence pulse from the adapter or end effector.

Abstract: An instrument drive unit includes a housing configured to be coupled to a surgical robotic arm, a motor assembly, and a flex spool assembly. The motor assembly is rotatably disposed within the housing. The flex spool assembly includes a first printed circuit board mounted to the housing, a second printed circuit board configured to be non-rotatably coupled to and electrically connected to the motor assembly, and a first flex circuit. The first flex circuit has a first end portion connected to the first printed circuit board, a second end portion connected to the second printed circuit board, and an intermediate portion coiled about the second printed circuit board such that rotation of the motor assembly relative to the housing effects movement of the second end portion of the first flex circuit along an annular path.
