Publication number: 20100274086Abstract: A system measures a change in position of a medical appliance, such as an endoscopy capsule. A device uses this measurement in order to influence the position of the medical appliance. The medical appliance sends a signal that is received by a multiplicity of spatially separate receiving devices. The time profile of the phase differences between the received signals and a reference signal provides an indication of whether the medical appliance has moved. In the event of a movement being detected, a maneuvering device can be regulated by a regulating means in such a way that the maneuvering device generates forces and/or torques and applies them to the medical appliance to counteract the detected movement.Type: ApplicationFiled: December 8, 2008Publication date: October 28, 2010Inventors: Dirk Diehl, Ralph Oppelt, Johannes Reinschke

Publication number: 20100274087Abstract: In a coupled control mode, the surgeon directly controls movement of an associated slave manipulator with an input device while indirectly controlling movement of one or more non-associated slave manipulators, in response to commanded motion of the directly controlled slave manipulator, to achieve a secondary objective. By automatically performing secondary tasks through coupled control modes, the system's usability is enhanced by reducing the surgeon's need to switch to another direct mode to manually achieve the desired secondary objective. Thus, coupled control modes allow the surgeon to better focus on performing medical procedures and to pay less attention to managing the system.Type: ApplicationFiled: May 14, 2010Publication date: October 28, 2010Applicant: Intuitive Surgical Operations, Inc.Inventors: Nicola Diolaiti, David Q.

Patent number: 7819799Abstract: Apparatus for controlling force applied to and for manipulation of a surgical instrument. Movement and/or forces applied to the surgical instrument are preferably sensed within the apparatus. An actuator is preferably used to apply force to the surgical instrument for control and manipulation of the instrument. The apparatus applies variable force feedback to apply force to the surgical instrument in one or more degrees of freedom to provide an enhanced haptic experience to the user.Type: GrantFiled: October 27, 2005Date of Patent: October 26, 2010Assignee: Immersion Medical, Inc.Inventors: Gregory L. Merril, Richard L. Cunningham, J. Michael Brown, Robert F. Cohen, Philip G. Feldman

Patent number: 7811227Abstract: An endoscope apparatus includes an endoscope, a signal processing unit, and a communication unit. The endoscope includes an information storage section including an endoscope information memory and a first controller controlling readout of the information in the endoscope information memory. The endoscope is detachably connected to the signal processing unit, which includes a second controller issuing at least an instruction for a readout operation of the information to the information storage section. Data is transmitted and received between the first controller and the second controller through the communication unit. The endoscope apparatus includes a communication speed setting unit setting the communication speed of the communication unit to a higher communication speed allowable in the first controller and a switching unit switching the communication speed.Type: GrantFiled: August 23, 2006Date of Patent: October 12, 2010Assignee: Olympus Medical Systems Corp.Inventor: Takeshi Urasaki
