Publication number: 20110137322Abstract: Improved robotic surgical systems, devices, and methods include selectably associatable master/slave pairs, often having more manipulator arms than will be moved simultaneously by the two hands of a surgeon. Four manipulator arms can support an image capture device, a left hand tissue manipulation tool, a right hand tissue manipulation tool, and a fourth surgical instrument, particularly for stabilizing, retracting, tool change, or other functions benefiting from intermittent movement. The four or more arms may sequentially be controlled by left and right master input control devices. The fourth arm may be used to support another image capture device, and control of some or all of the arms may be transferred back-and-forth between the operator and an assistant. Two or more robotic systems each having master controls and slave manipulators may be coupled to enable cooperative surgery between two or more operators.Type: ApplicationFiled: December 3, 2010Publication date: June 9, 2011Applicant: Intuitive Surgical OperationsInventors: Frederic H.

Publication number: 20100332031Abstract: A minimally-invasive surgical system includes a slave surgical instrument having a slave surgical instrument tip and a master grip. The slave surgical instrument tip has an alignment in a common frame of reference and the master grip, which is coupled to the slave surgical instrument, has an alignment in the common frame of reference. An alignment error, in the common frame of reference, is a difference in alignment between the alignment of the slave surgical instrument tip and the alignment of the master grip. A ratcheting system (i) coupled to the master grip to receive the alignment of the master grip and (ii) coupled to the slave surgical instrument, to control motion of the slave by continuously reducing the alignment error, as the master grip moves, without autonomous motion of the slave surgical instrument tip and without autonomous motion of the master grip.Type: ApplicationFiled: June 30, 2009Publication date: December 30, 2010Applicant: Intuitive Surgical, Inc.Inventors: Brandon D.

Patent number: 7574250Abstract: An input device of a teleoperator system can be operatively associated with an image of a surgical worksite. Movement of the image may correspond to movement of the input device so that the worksite image appears substantially connected to the input device. The operator can manipulate the worksite into a desired position, typically by repositioning of an image capture device. Dedicated input devices may be provided for a surgical instrument.Type: GrantFiled: February 4, 2003Date of Patent: August 11, 2009Assignee: Intuitive Surgical, Inc.Inventor: Gunter D. Niemeyer

Patent number: 7155315Abstract: Enhanced telepresence and telesurgery systems automatically update coordinate transformations so as to retain alignment between movement of an input device and movement of an end effector as displayed adjacent the input device. A processor maps a controller workspace with an end effector workspace, and effects movement of the end effector in response to the movement of the input device. This allows the use of kinematically dissimilar master and slave linkages. Gripping an input member near a gimbal point and appropriate input member to end effector mapping points enhance the operator's control. Dexterity is enhanced by accurately tracking orientational and/or angles of movement, even if linear movement distances of the end effector do not correspond to those of the input device.Type: GrantFiled: December 12, 2005Date of Patent: December 26, 2006Assignee: Intuitive Surgical, Inc.Inventors: Gunter D.

Patent number: 6837883Abstract: Improved robotic surgical systems, devices, and methods often include a first assembly with a surgical end effector supported and manipulated relative to a first base by a first robotic linkage, while a second surgical end effector manipulated and supported relative to a second, independent base by a second robotic linkage. One or more of these robotic assemblies may be moved relative to the other. To coordinate the end effector movements with those of input devices being manipulated by a surgeon relative to a display of a surgical worksite, the processor deriving the commands for movement of the robotic linkages may make use of a signal indicating a relative orientation of the bases of the robotic arm assemblies. Surprisingly, the robotic arm assemblies may not transmit signals to the processor indicating a relative translational position of the bases.Type: GrantFiled: October 5, 2001Date of Patent: January 4, 2005Assignee: Intuitive Surgical, Inc.Inventors: Frederic H.
