  • Patent number: 9629517
    Abstract: A scanning endoscope system includes: a fiber that guides illuminating light emitted from a light source; a first actuator provided on a side of the fiber, the first actuator expanding/contracting according to an applied voltage, thereby swinging the fiber; a second actuator disposed at a position facing the first actuator across the fiber, the second actuator expanding/contracting according to an applied voltage, thereby swinging the fiber; and a drive signal output section that applies a first drive signal that varies with reference to a first voltage that brings the first actuator into a contracted state to the first actuator and applies a second drive signal that varies with reference to a second voltage that brings the second actuator into a contracted state to the second actuator.

  • Patent number: 9615724
    Abstract: A gas feeding duct, a suction duct, a first valve that is installed in the gas feeding duct and opens a flow passage only when gas feeding is underway, and a second valve that is installed in a part of the flow passage on an upstream side relative to the first valve, and opens the flow passage K along with gas feeding and closes the flow passage at least when suction is underway are included, and when neither gas feeding nor gas suctioning is underway, the second valve closes the flow passage in conjunction with the first valve unexpectedly opening the flow passage as a result of pressure variation in a part of the gas feeding duct on a downstream side relative to the first valve and thereby prevents reverse flow of a fluid to the upstream side relative to the second valve.

  • Patent number: 9603515
    Abstract: A catheter for tracheal or bronchial suction including a unit for displaying the artificial airways, the trachea and the bronchial tree so as to allow the removal of secretions; in particular, the catheter for tracheal or bronchial suction includes optical fibers, a microcamera or another visualization technology positioned in the distal end. The operator can identify the position of the distal end, of the artificial airways, of the trachea and of the bronchial tree on the screen. Therefore, it is possible to ensure that the tube of the catheter is adjacent to or inside collections of fluid secretions or other material to be sucked up. The suction can be selectively applied to avoid damage to the mucosa and to facilitate the more complete elimination of secretions.

  • Patent number: 9545194
    Abstract: An embodiment in accordance with the present invention provides a scope lens cleaning system disposed within a trocar shaft to allow the surgeon to clean the scope lens without losing orientation of the operative field. The lens cleaning system is configured to remove solid debris, liquid, and condensation from the scope lens. The cleaning system includes a first cleaning component configured to remove the solid debris from the scope lens. A second cleaning component is configured to remove the liquid and condensation from the scope lens. A third cleaning component wicks the solid debris and liquid away from the cleaning components and the scope lens and allows it to fall out the end of the trocar shaft. The cleaning system minimizes distraction during the surgical procedure to improve efficiency and safety.

  • Patent number: 9504371
    Abstract: An endoluminal surgical instrument has first and second steering controls on a handle. A flexible shaft attached to the handle has a distal steerable end including a first link and a second link separated by a plurality of intermediate links. First and second steering elements, such as pairs of steering wires, are linked to first and second steering controls and to the first and second links. One or more of the links is pivotable through an angle of at least 30 degrees relative to an adjoining link. The set back position of the second steering elements from the first steering elements, and the pivoting capability of the links allows the steerable end to be steered into a small bend radius. This makes the instrument highly maneuverable for use in endoluminal surgery, such as incision-less surgery of the stomach.
