Patent number: 11583308Abstract: Apparatus for generating torsional-mode ultrasonic vibrations, for example in a surgical tool, comprises an ultrasonic transducer that would conventionally produce longitudinal-mode ultrasonic vibrations, with a long, hollow, cylindrical, mode converter mounted coaxially to its distal end. A plurality of holes are formed through the walls of the mode converters. These holes are arranged in multiple parallel helical rows, extending along and around the cylindrical mode converters. Holes within the same row are spaced relatively closely, compared with the spacing between rows. Relationships have been established between the hole diameter (d), the spacing between rows (W), the spacing between holes in the same row (l), the spacing between individual holes in adjacent rows (L), and the overall diameter of the mode converter (D). In a preferred version, the holes through the walls of the second mode converter are tapered inwardly, rather than being cylindrical holes as in the first mode converter.Type: GrantFiled: January 17, 2018Date of Patent: February 21, 2023Inventors: Sean Martin Badcott, Stephen Michael Radley Young, Michael John Radley Young

Patent number: 11576742Abstract: A control system for regulating operative control of a surgical instrument by a remote surgeon input device. The surgical instrument is supported by an articulated robot arm, and comprises an end effector connected to a shaft by an articulated coupling. The remote surgeon input device is capable of operatively controlling the surgical instrument by controlling articulation of the end effector, and controlling articulation of the robot arm and coupling. On receiving a request to engage operative control of the surgical instrument by the surgeon input device, the control system initially engages operative control of articulation of the robot arm and coupling by the surgeon input device, whilst maintaining disengagement of operative control of articulation of the end effector by the surgeon input device. Subsequently, the control system engages operative control of articulation of the end effector by the surgeon input device following a manipulation of the surgeon input device.Type: GrantFiled: March 9, 2018Date of Patent: February 14, 2023Assignee: CMR SURGICAL LIMITEDInventors: Edward James Wildin Tucker, Gordon Thomas Deane, Rachel Marie Garsed, Rebecca Anne Cuthbertson, Ross Hamilton Henrywood
