  • Patent number: 10973391
    Abstract: A system for virtual reality/mixed reality viewing of a surgical procedure includes an endoscope having an elongated flexible or rigid main body with a proximal end and a distal end. A spherical element is coupled to the distal end. A plurality of wide field-of-view cameras or optical collections lenses are aligned about the spherical element to provide 360 degree omnidirectional stereoscopic visualization. A fiber optic illumination strip is positioned around the periphery of the spherical element adjacent each camera. A central processing unit is in communication with the plurality of cameras/lenses configured to receive real-time video from each of the plurality of cameras or lenses. A partial field-of-view virtual reality headset or a mixed reality headset is electronically coupled to the central processing unit. The headset displays real-time video from a select portion of the plurality of cameras or lenses, which provides 360 degree omnidirectional visualization based upon a position of the headset.

  • Patent number: 10959606
    Abstract: The image acquisition unit acquires an image captured by an endoscope. The extraction unit extracts a blood vessel of an observation target. The index value calculation unit calculates a plurality of blood vessel index values based on the blood vessel. The determination unit determines whether each of the plurality of blood vessel index values is a normal value or an abnormal value. The color information setting unit sets color information for an abnormal index value, which is the blood vessel index value determined to be the abnormal value by the determination unit, or sets color information for a normal index value, which is the blood vessel index value determined to be the normal value by the determination unit. The image generation unit generates an emphasized image, in which the blood vessel is emphasized, based on the color information.

  • Patent number: 10959807
    Abstract: 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.

  • Patent number: 10881268
    Abstract: A device to set and retrieve a reference point during a surgical procedure. The device (12) has an endoscope (312) which captures several images successively as an image sequence and generates image data corresponding to the image sequence, which data are then processed and output on at least one display unit (44). A control unit (40) determines the first position of a first point at a first point in time, a second position of a second point at a second point in time, and a first distance vector between the first position and the second position. The positions are determined via the kinematic chain of a manipulator arm (16a,16b).

  • Patent number: 10881281
    Abstract: A capsule endoscope includes a sensor, an analyzer, a counter, a signal generator, and an imager. A count value becomes a reference value when an imaging synchronization signal is generated. When the count value changes from the reference value to a first predetermined value, the signal generator generates the imaging synchronization signal. A second time that is necessary for the count value to change from the reference value to the first predetermined value is fixed or variable. The second time is longer than a first time in a case in which the second times is fixed. A maximum value of the second time is longer than the first time in a case in which the second time is variable.
