    摘要： A dilator, dilating a narrowed part of a paranasal sinus, includes an end effector, and the end effector includes a pair of treatment pieces openable and closable relative to each other. Each of the treatment pieces includes a treatment surface facing a side on which the treatment piece opens, and each of the treatment surfaces includes an inclined surface inclined to be closer to a side on which the treatment piece closes as a distance to a distal end of the treatment piece decreases. The pair of inclined surfaces become parallel or substantially parallel to each other when the treatment pieces are opened to a maximum angle. The end effector opens anisotropically.

    摘要： An insertion assist device for an endoscope includes a grip, an operation portion, a liquid storage, and a tubular member. The grip includes a channel through an inside of which an insertion portion of the endoscope is inserted. The operation portion is configured to advance the insertion section by moving forward relative to the grip. The liquid storage is provided on an interior portion of the grip and configured to store a liquid. The tubular member is provided on an interior portion or an exterior portion of the insertion portion of the endoscope, is connected to the liquid storage at one end of the tubular member, and is configured to guide the liquid toward another end of the tubular member opposite to said one end.

    摘要： The disclosed technology is directed to an endoscopic system comprises an endoscope having a shank and a photodetector engaged with one another and having an optical axis in a direction transverse to the shank. A display device for displaying an image acquired through the photodetector. A first probe is disposed in the endoscope on or around the optical axis at a position off the shank. A second probe is disposed in the endoscope at or near a position where the shank and the optical axis intersect with each other. A sensor for detecting the position of the first probe and the position of the second probe and a controller. The controller is configured to establish a first reference direction in an actual space. To acquire a direction from the second probe toward the first probe and to perform a process for indicating the first reference direction to a user.

    摘要： 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.
