Patent number: 11484379Abstract: A local haptic hand controller is provided for enabling an operator to remotely perform fine manipulation, such as microsurgery, in conjunction with a remotely located robotic manipulator, for example at which the microsurgery is to be performed. The local haptic hand controller includes a base, a kinematic structure in communication with the base and comprises a gimbal as an end effector. A local surgical tool is provided at the gimbal and has a shape and construction substantially similar to a remote surgical tool provided at the remote robotic manipulator. A control system is in communication with the local surgical tool and with the remote surgical tool, and configured to enable operation of the local haptic hand controller when a local surgical tool identifier matches a remote surgical tool identifier.Type: GrantFiled: December 28, 2018Date of Patent: November 1, 2022Assignee: ORBSURGICAL LTD.Inventors: Garnette Roy Sutherland, Hamidreza Hoshyarmanesh, Kourosh Zareinia, Sanju Lama

Patent number: 10987155Abstract: Bipolar forceps of the type where each of the prongs has a manually engageable portion spaced from the tip for manual squeezing of the prongs and an electrical supply system for applying a high-frequency electric current between tool tips to dissect through tissue planes and/or seal blood vessels includes a set of force measuring sensors for measuring forces, particularly squeezing forces, applied to the prongs at the tip. A temperature sensor is included to provide temperature information and temperature compensation. The sensors are applied to each prong in opposing pairs on the inside and outside surfaces and the outputs thereof are applied to a bridge arrangement. The signals are sent to a processor for generating warning signals and for recording forces for training purposes where a haptic system can be used.Type: GrantFiled: June 28, 2013Date of Patent: April 27, 2021Inventors: Garnette Roy Sutherland, Kourosh Zareinia, Liu Shi Gan, Tomas Jens Hirmer, Sanju Lama

Patent number: 8396598Abstract: A robot system for use in surgical procedures has two movable arms each carried on a wheeled base with each arm having a six of degrees of freedom of movement and an end effector which can be rolled about its axis and an actuator which can slide along the axis for operating different tools adapted to be supported by the effector. Each end effector including optical force sensors for detecting forces applied to the tool by engagement with the part of the patient. A microscope is located at a position for viewing the part of the patient. The position of the tool tip can be digitized relative to fiducial markers visible in an MRI experiment. The workstation and control system has a pair of hand-controllers simultaneously manipulated by an operator to control movement of a respective one or both of the arms. The image from the microscope is displayed on a monitor in 2D and stereoscopically on a microscope viewer. A second MRI display shows an image of the part of the patient the real-time location of the tool.Type: GrantFiled: November 22, 2006Date of Patent: March 12, 2013Assignee: Neuroarm Surgical Ltd.Inventors: Garnette Roy Sutherland, Deon Francois Louw, Paul Bradley McBeth, Tim Fielding, Dennis John Gregoris
