The user interface is configured to enable finger-touch selection of a fluid flow rate through the tubing and configured to operate in at least one of a first mode or a second mode. In the first mode, the flow rate is controlled via direct selection of one of a plurality of selectable digital numeric values, while in the second mode the flow rate is controlled via user selection of one alphanumeric identifier within a scale of alphanumeric identifiers. Each respective alphanumeric identifier directly corresponds to just one instrument size within a scale of instrument sizes.

  • Patent number: 10314463
    Abstract: A surgical robotic system automatically calibrates tubular and flexible surgical tools such as endoscopes. By accounting for nonlinear behavior of an endoscope, the surgical robotic system can accurately model motions of the endoscope and navigate the endoscope while performing a surgical procedure on a patient. The surgical robotic system models the nonlinearities using sets of calibration parameters determined based on images captured by an image sensor of the endoscope. Calibration parameters can describe translational or rotational movements of the endoscope in one or more axis, e.g., pitch and yaw, as well as a slope, hysteresis, or dead zone value corresponding to the endoscope's motion. The endoscope can include tubular components referred to as a sheath and leader. An instrument device manipulator of the surgical robotic system actuates pull wires coupled to the sheath or the leader, which causes the endoscope to articulate.

  • Patent number: 10314464
    Abstract: An insertion apparatus includes an insertion section, a rotational housing, a motor, and a controller. The motor rotates the rotational housing. The controller designates a rotational direction of the motor. The controller limits the rotational direction of the motor to allow the insertion section to move only in a removal direction when inspection control for inspecting an operation relative to an insertion direction of the insertion section is initiated.

  • Patent number: 10105039
    Abstract: The present specification describes a jet distributor provided to supply fluids to each of a plurality of jet openings in a multi-jet endoscope tip. In an embodiment, the jet distributor is supplied with a fluid from a jet pump. The jet distributor includes at least two fluid channels to provide the fluid supplied via the jet pump to the front-jet, right-side-jets and left-side-jets in the endoscope tip. The jet-distributor includes a motor which rotates a rotating plug. The rotating plug includes an internal fluid pathway which becomes intermittently aligned with each of a plurality of fluid output channels in the jet distributor as the plug rotates, thereby providing fluid in a successive manner to the jets in the endoscope tip.

  • Patent number: 10084963
    Abstract: A stage apparatus includes a base member, a movable member which moves relative to the base member, thrust generators which generate thrust forces against the movable member, and a position detector which detects a translation position and a rotational position of the movable member relative to the base member. An interaction of the thrust forces causes the movable member to at least one of: translate, rotate, translate while rotating, and translate after rotating relative to the base member. The position detector includes permanent magnets fixed to one of the movable member and the base member, and pairs of magnetic sensors fixed to the other of the movable member and the base member. The position detector detects the translation position and the rotational position of the movable member relative to the base member based on detection signals input from the pairs of magnetic sensors.
