Publication number: 20230256609Abstract: An electronic circuit for a surgical robotic system includes a central power node, a first voltage bus that electrically couples a first power source to the node, a second voltage bus that electrically couples a second power source to the node, and several robotic arms, each arm is electrically coupled to the node via an output circuit breaker and is arranged to draw power from the node. Each bus is arranged to provide power from a respective power source to the node and each bus has an input circuit breaker that is arranged to limit a first output current flow from the node and into the bus. Each breaker that is arranged to limit a second output current flow from the node and into a respective arm. A breaker is arranged to open in response to a fault occurring within the respective arm, while the other breakers remain closed.Type: ApplicationFiled: April 25, 2023Publication date: August 17, 2023Inventors: Rochelle Rea, Klaus Zietlow, Adam Hoffman, Yiqi Zeng

Patent number: 9993135Abstract: An endoscopic system can include an endoscope shaft having a proximal end and a distal end. The endoscopic system can have a sensor system that includes an electrically active sensor mounted proximate the distal end and positioned to sense at least one characteristic of an environment in which the distal end is located, a data signal transmission line connected to the sensor to transmit data signals between the sensor and a signal processor, and an electrical power transmission line connected to the sensor to transmit power to the sensor. The endoscopic system also can include a floating ground element arranged to provide an electrical reference for the sensor system. Voltage induced by an electromagnetic interference external to the endoscopic system on at least one of the data signal transmission line or electrical power line is substantially similar to the voltage induced by the electromagnetic interference on the floating ground element.Type: GrantFiled: November 14, 2013Date of Patent: June 12, 2018Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Dominique Brichard, David D.
