Patent number: 9095253Abstract: The invention provides articulating mechanisms, and flexible members and flexible segments that can form such articulating mechanisms. The mechanisms are useful, for example, for remote steering, guidance and/or manipulation of various instruments and tools at a targeted location. The mechanisms, members or segments include links connected by flexible hinges. The proximal and distal ends of the mechanisms are connected by at least one set of cables in such a fashion that a proximal active flexible segment forms a discrete pair with a distal active flexible segment. Movement of active flexible segments at the proximal end of the mechanism results in a corresponding, relative movement of segments at the distal end of the mechanism. This configuration allows each flexible segment pair to move independently of one another and also permits the articulating mechanism to undergo complex movements and adopt complex configurations.Type: GrantFiled: November 2, 2012Date of Patent: August 4, 2015Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Cameron D. Hinman, David J. Danitz

Patent number: 9089354Abstract: Featured are systems, devices and apparatuses for use in minimally invasive surgical, diagnostic or therapeutic methods and/or techniques, in particular methods and/or techniques for a mammalian throat. In particular embodiments, a dexterity apparatus including one or more dexterity devices is featured, where each of the dexterity devices comprises surgical tools and each is configured and arranged with end-tip dexterity for enhanced manipulation. A portion of the dexterity devices is snake like, which is re-configurable (i.e., can be bent) so as to in effect maneuver the surgical tool and put the tool in a desired position with respect to the surgical site. Another portion of the dexterity device includes the surgical tool thereby providing the capability of performing surgical actions such as sewing, gripping, soft tissue manipulation, cutting and suction of saliva, blood and other materials from the surgical site.Type: GrantFiled: January 14, 2013Date of Patent: July 28, 2015Assignee: The Johns Hopkins UniversityInventors: Nabil Simaan, Russell H. Taylor, Paul Flint, Gregory Chirikjian, David Stein

Patent number: 9085085Abstract: The invention provides an articulating mechanism useful, for example, for remote manipulation of various surgical instruments and diagnostic tools within, or to, regions of the body. Movement of segments at the proximal end of the mechanism results in a corresponding, relative movement of segments at the distal end of the mechanism. The proximal and distal segments are connected by a set of cables in such a fashion that each proximal segment forms a discrete pair with a distal segment. This configuration allows each segment pair to move independently of one another and also permits the articulating mechanism to undergo complex movements and adopt complex configurations. The articulating mechanisms may also be combined in such a way to remotely mimic finger movements for manipulation of an object or body tissue.Type: GrantFiled: August 28, 2013Date of Patent: July 21, 2015Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: David J.

Patent number: 9039607Abstract: A shaft element for an endoscopic instrument includes a first, proximal shaft segment and a second, distal shaft segment, such that the second shaft segment is connected with the first shaft segment by three connecting elements, such that the connecting elements each include a first two-axis joint, such that the first joints form a triangle and such that the first connecting element is connected with the first shaft segment in such a way that it cannot slide with respect to the latter in a longitudinal direction, and a second and third connecting elements can each be slid with respect to the first shaft segment in a longitudinal direction independently of one another. The invention also relates to an endoscopic instrument, in particular an endoscope with such a shaft segment.Type: GrantFiled: August 12, 2011Date of Patent: May 26, 2015Assignee: KARL STORZ GMBH & CO.

Patent number: 9011318Abstract: A highly articulated robotic probe (HARP) is comprised of a first mechanism and a second mechanism, one or both of which can be steered in desired directions. Each mechanism can alternate between being rigid and limp. In limp mode the mechanism is highly flexible. When one mechanism is limp, the other is rigid. The limp mechanism is then pushed or pulled along the rigid mechanism. The limp mechanism is made rigid, thereby assuming the shape of the rigid mechanism. The rigid mechanism is made limp and the process repeats. These innovations allow the device to drive anywhere in three dimensions. The device can “remember” its previous configurations, and can go anywhere in a body or other structure (e.g. jet engine). When used in medical applications, once the device arrives at a desired location, the inner core mechanism can be removed and another functional device such as a scalpel, clamp or other tool slid through the rigid sleeve to perform.Type: GrantFiled: June 24, 2005Date of Patent: April 21, 2015Assignee: Carnegie Mellon University and University of Pittsburg—Of the Commonwealth System of Higher EducationInventors: Howard M. Choset, Alon Wolf, Marco A. Zenati

Patent number: 8992421Abstract: A highly articulated robotic probe comprises an outer sleeve and an inner core. The outer sleeve and inner core include a plurality of links. The links of the outer sleeve and inner core are configured to pivot relative to one another. Various characteristics of the links determine the overall pivot angle of the articulated probe. Each of the plurality of links may have one or more channels. The channels form a semi-continuous passage from link to link and are configured to receive an elongated member such as an inner core, tool or cable. One or more cables may be used to control the outer links of the outer sleeve and the inner links of the inner core. Various characteristics of the cables determine the overall performance of the articulated probe.Type: GrantFiled: October 21, 2011Date of Patent: March 31, 2015Assignee: Medrobotics CorporationInventors: Joseph A. Stand, Robert A. Didomenico, Brett Zubiate, Ian J. Darisse, J. Christopher Flaherty

Patent number: 8986196Abstract: A surgical instrument extends through a guide tube and exits at an intermediate position of the guide tube. The instrument includes a parallel motion mechanism that changes the position of a distal end of the surgical instrument without changing the orientation of the distal end. An image capture component is at the distal end of the guide tube, and a joint allows the image capture component to move while the intermediate position remains stationary. The configuration allows a cross section of the guide tube to be oblong. In some aspects, a joint for the image capture component is placed between exit ports for surgical instruments, which allows the guide tube cross section to be further reduced.Type: GrantFiled: June 13, 2007Date of Patent: March 24, 2015Assignee: Intuitive Surgical Operations, Inc.Inventors: David Q. Larkin, Thomas G. Cooper, David C. Shafer, David J. Rosa, Matthew R. Williams, Eugene F. Duval
