  • Publication number: 20210186309
    Abstract: An enhanced flexible robotic endoscopy apparatus includes a main body and flexible elongate shaft. The main body comprises a proximal end, a distal end and a housing that extends to the proximal end and the housing comprises a plurality of surfaces and a plurality of insertion inlets which reside on at least one of the surface of the housing at the proximal end of the main body, through which a plurality of channels for endoscopy are accessible. Each of the insertion inlets has insertion axis corresponding thereto, along which flexible elongate assemblies are insertable, with the insertion axes of the insertion inlets being parallel to the central axis of the flexible elongate shaft at the proximal end of the flexible elongate shaft.

  • Publication number: 20200315720
    Abstract: An embodiment of the invention is an endoscopy system with newly designed docking block, brake control, wire tension adjustment, bending angle sensor, memory chip data storage, valve control, imaging lens cleaning, optimized lumen arrangement and distal position sensor. The docking block can have a one-touch retaining mechanism. Braking control can be accessed by the endoscopist at the hand grip or knobs. Wire tension can be relaxed or tightened in response to surgeon or endoscopist control. Bending angle sensors can protect surgical instruments. Memory chip can store usage data of the endoscope. Multiple valves can have priority control. Lenses can be cleaned with one touch of a button. Lumens can be arranged to maximize imaging and lighting angles. Position markers accompanied with sensors can position the distal end of the endoscope automatically in the optimal position.

  • Publication number: 20200221935
    Abstract: An endoscope system is provided. The system comprises an endoscope having a hollow tube formed therein; and an instrument for insertion through the hollow tube, wherein the instrument has a first end for operational control and a second distal end for instrument operation at a distal end of the endoscope, wherein the distal end of the endoscope has an illumination device and a vision device for providing illuminated vision at the distal end of the endoscope for operational control of the instrument operation at the distal end of the instrument, and wherein the distal end of the instrument and the distal end of the endoscope are interoperably coupled for rotational control of the instrument with respect to the endoscope.

  • Publication number: 20190191967
    Abstract: A flexible robotic endoscopy slave system includes an endoscope body and a flexible elongate shaft extending therefrom into which at least one tendon driven robotic endoscopic instrument is insertable; a docking station with which the endoscope body is releasably dockable; and a translation mechanism for selectively longitudinally displacing the endoscopic instrument(s) within the flexible elongate shaft when the endoscope body is docked. The translation mechanism can carry and selectively displace actuators that drive each robotic endoscopic instrument by way of tendons. At least one degree of freedom (DOF) of robotic instrument motion is controlled by a pair of actuators and a corresponding pair of tendons. Actuation engagement structures releasably couple the actuators to an adapter structure for driving each endoscopic instrument. Tendon pretensioning can occur automatically under programmable control.
