Patent number: 11617499Abstract: A system comprises an instrument having a bendable portion with first and control elements extending in the bendable portion and a control system operably coupled to an actuator and a sensor. The control system operates to, while the bendable portion is in a neutral position, command the actuator to move the first control element a first amount until slack is removed from the first control element and command the actuator to move the second control element a second amount until slack is removed from the second control element. The control system also receives a first control element calibration position after moving the first control element the first amount and receives a second control element calibration position after moving the second control element the second amount. The control system also commands the actuator to bend the bendable portion from the neutral position and determine a resulting shape of the bendable portion.Type: GrantFiled: July 30, 2021Date of Patent: April 4, 2023Assignee: INTUITIVE SURGICAL OPERATIONS, INC.Inventors: Kevin Durant, David S.

Patent number: 10959807Abstract: A system may comprise an instrument with an elongate body portion to be moved along a path, one or more datums, and a plurality of sense elements disposed at positions spaced along a length of the elongate body portion. Each sense element may sense or be sensed by one of the datums when in proximity to the datum. The system may also include a processor configured to compare signals transmitted from the datums or from the sense elements, including a first signal and a second signal, and identify, based on the comparison, a state of motion of the elongate body chosen from a state of motion in a forward direction (insertion) along a path and a state of motion in a rearward direction (withdrawal) along the path. The processor may identify the state of motion of the elongate body based on whether the first signal is lower than or higher than the second signal and whether the first and second signals are both increasing or decreasing.Type: GrantFiled: May 9, 2018Date of Patent: March 30, 2021Assignee: Intuitive Surgical Operations, Inc.Inventors: Robert M.
