  • 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.

The insufflation apparatus is connected to an endoscope and an insertion assisting tool which guides the endoscope into the gastrointestinal tract. Carbon dioxide can be insufflated into a gastrointestinal tract of a patient through an internal conduit of the endoscope according to an operator's operation (manual insufflation). When the operator instructs the insufflation apparatus to perform the automatic insufflation, carbon dioxide is intermittently insufflated into the gastrointestinal tract through the insertion assisting tool so as to make the pressure inside the gastrointestinal tract become a set pressure (automatic insufflation). The insufflation flow rate of the manual insufflation is switched between the high flow rate and the low flow rate according to ON/OFF state of the automatic insufflation.

  • Patent number: 9182337
    Abstract: An insertion module inserted into inside of an observed object includes a light-source light emitting module, around its distal end, configured to emitted light from a light source and a detector, provided close to the distal end, configured to detect a light quantity of incident visible light. A controller controls the light source such that a null signal is transmitted from the light-source light emitting module, the null signal being characteristic for detection of the position of the distal end and obtained by making at least light of a predetermined wavelength region have an absence of visible light. The detector performs detecting operation in a period in which the null signal is transmitted. A determination module performs determination relating to the position of the distal end, based on detection information outputted by the detector.

  • Patent number: 9113806
    Abstract: An image converter receives image data of an object and performs a kind of image conversion on the image data to generate converted image data for display. A measurement section measures at least one spatial characteristic of the object based on: the converted image data, and optical data, which relates to optical characteristics of an optical system through which the image data of the object has been obtained, and which is made to correspond to the kind of image conversion performed by the image converter. Alternatively, a measurement section measures at least one spatial characteristic of the object by relating, based on the kind of image conversion, coordinates of the converted image data to coordinates of the image data of the object before the image conversion, and by measuring the at least one spatial characteristic based on the coordinates of the image data of the object before the image conversion.

  • Patent number: 9066677
    Abstract: An illumination unit includes semiconductor light sources, a target light quantity setting unit for setting a target light quantity for a total outgoing light quantity, a light quantity ratio setting unit for setting an outgoing light quantity ratio among the semiconductor light sources, an amplitude value setting unit for setting amplitude values of driving signals for the semiconductor light sources based on the set outgoing light quantity ratio and a driving signal generating unit for generating the driving signals by use of common pulse modulation control while keeping the set amplitude values. When the target light quantity is set, a driving pulse signal corresponding to the target light quantity is set in common among the semiconductor light sources. The driving pulse signal is formed to have amplitude values corresponding to the outgoing light quantity ratio to generate individual driving signals for driving the semiconductor light sources respectively.

  • Patent number: 9028396
    Abstract: Broadband light and narrowband light are simultaneously projected toward a subject. The subject is imaged by a color CCD to obtain a blue signal, a green signal, and a green signal. A base image is generated from the signals of three colors. Based on a luminance ratio B/G between the blue signal and the red signal, a B/G image is generated. A high frequency component is extracted from the B/G image to obtain a superficial-blood-vessel extracted image, and a medium frequency component is extracted from the B/G image to obtain a middle-deep-blood-vessel extracted image. Based on the base image and one of the superficial-blood-vessel extracted image and the middle-deep-blood-vessel extracted image, a blood vessel emphasized/de-emphasized image, in which the superficial blood vessels or the middle-deep blood vessels are emphasized or de-emphasized, is generated. The blood vessel emphasized/de-emphasized image is displayed on a monitor.

  • Patent number: 9011318
    Abstract: A highly articulated robotic probe (HARP) is comprised of a first mechanism and a second mechanism, one or both of which can be steered in desired directions. Each mechanism can alternate between being rigid and limp. In limp mode the mechanism is highly flexible. When one mechanism is limp, the other is rigid. The limp mechanism is then pushed or pulled along the rigid mechanism. The limp mechanism is made rigid, thereby assuming the shape of the rigid mechanism. The rigid mechanism is made limp and the process repeats. These innovations allow the device to drive anywhere in three dimensions. The device can “remember” its previous configurations, and can go anywhere in a body or other structure (e.g. jet engine). When used in medical applications, once the device arrives at a desired location, the inner core mechanism can be removed and another functional device such as a scalpel, clamp or other tool slid through the rigid sleeve to perform.
