Abstract: A medical endoscopic device for crushing urinary stones having an insertion portion including an optical window, an illumination window, a laser fiber, an elongate internal channel, and a procedure tube coaxially and movably disposed inside the elongate internal channel is disclosed. The distal end of the procedure tube is comprised of a distal tip portion having a diameter larger than that of the attached elongate portion. The distal tip portion of the tube also includes openings for flushing the fragments of the urinary stones and the like. The washed out fragments are suctioned through the opening between the inner diameter surface of the elongate internal channel and the outer peripheral surface of the tube and the distal tip portion may be used to scrape out the contaminated fragments of the urinary stones within the elongate internal channel.

Abstract: A medical instrument includes an insertion portion, first transmitting coils, second transmitting coils, a signal control unit, a position detection unit, a memory, and a position estimating unit. The signal control unit controls the first transmitting coils to transmit magnetic fields during a first predetermined period and controls the second transmitting coils to transmit magnetic fields during a second predetermined period. The position detection unit detects positions of the first transmitting coils during the first predetermined period and detects positions of the second transmitting coils during the second predetermined period. The memory stores the positions of the first transmitting coils. The position estimating unit estimates a shape of the insertion portion based on the positions of the second transmitting coils and the positions of the first transmitting coils stored in the memory.

Abstract: An endoscope system includes an endoscope that acquires an image of a subject and a processor. The processor acquires position and posture information of the endoscope, estimates a three-dimensional shape of the subject based on the image and the position and posture information, generates, based on the position information, a cross section crossing a trajectory on which the endoscope passed, and determines an erroneous estimation portion based on a shape characteristic of the three-dimensional shape on the cross section.

Abstract: An electrode unit includes: an electrode supporting member provided with a pair of distal end rigid members, surfaces of which are covered by an electrically insulating material, and an elastic region having lower bending rigidity than bending rigidity of each of the pair of distal end rigid members; an electrode configured with electrode bodies respectively protruding downward from the pair of distal end rigid members of the electrode supporting member and a spanning portion that spans between respective lower end portions of the electrode bodies; and an operation member provided in a proximal end rigid member, and configured to move relative to the proximal end rigid member to cause the electrode to move in a direction in which the electrode protrudes relative to the distal end rigid members.

Abstract: A navigation system includes an alignment unit configured to generate corrected position information in which position information of a viewpoint of an endoscope that is inserted in a subject is aligned with a three-dimensional image of a luminal organ, a determination unit configured to determine performance/non-performance of observation of a branch conduit based on the corrected position information, a target setting unit configured to set one unobserved conduit as a first target region based on a distance between the position information of the current viewpoint and the unobserved conduit, and a navigation information generation unit configured to generate navigation information for the first target region.
