Publication number: 20190357858Abstract: A method for controlling an orientation of a steerable distal portion of an elongate instrument, said instrument comprising at least one tensioning member attached to said steerable distal portion may include receiving an input command at a controller for articulation of said steerable distal portion, the articulation correlating to an approximate y-bend and an approximate x-bend of said steerable distal portion; calculating an approximate overall bend from said approximate y-bend and said approximate x-bend; and setting a limit of said approximate overall bend beyond which said steerable distal portion is not permitted to achieve. The method may further include one of: causing actuation of said at least one tensioning member to achieve said y-bend and said x-bend on a condition of said calculated approximate overall bend being equal to or less than said limit, and repeating the receiving, calculating, and setting steps on a condition of said calculated approximate overall bend being greater than said limit.Type: ApplicationFiled: August 9, 2019Publication date: November 28, 2019Applicant: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Robert ENO, Amir BELSON, David BLAHA, David MINTZ, Bruce R.

Patent number: 10426412Abstract: The present invention relates, generally, to reporting the approximate three-dimensional orientation of the steerable distal portion of an endoscope to the user of the endoscope. More particularly, the present invention relates to a system and method for providing the endoscope-user a display from which to more easily determine the approximate three-dimensional orientation of the steerable distal portion of the endoscope, thereby facilitating navigation of the endoscope. The present invention also relates to a system and method for limiting the amount the steerable distal portion can bend overall to reduce or eliminate the user's ability to over-retroflex the steerable distal portion of the endoscope.Type: GrantFiled: May 17, 2016Date of Patent: October 1, 2019Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Robert Eno, Amir Belson, David Blaha, David Mintz, Bruce R.
