Abstract: An endoscope has an insertion portion inserted through a living body, an illumination fiber arranged at a distal end of the insertion portion and irradiates the living body with illumination light, a detection fiber which detects return light from the living body, an actuator which swings a free end of the illumination fiber, and a ferrule which has a through-hole based on a diameter of the illumination fiber and is arranged between the illumination fiber and the actuator. The actuator has an actuator arranged at a first side face of the ferrule and an actuator arranged at a second side face of the ferrule that is different from a face point-symmetric to the first side face with respect to an axial direction of the illumination fiber.

Abstract: The disclosed technology is directed to an endoscope processor used in an endoscope system which comprises a receptacle configured to receive a plug of an endoscope. The plug includes an illumination plug terminal, an electric plug terminal, and a light-receiving plug terminal. The receptacle includes an illumination receptacle terminal that is displaceable within a predetermined range in a housing for the receptacle and is to be connected to the illumination plug terminal. An electric receptacle terminal is displaceable within a predetermined range in the housing and is to be connected to the electric plug terminal. A light-receiving receptacle terminal that is arranged between the illumination receptacle terminal and the electric receptacle terminal, is attached relative to the housing and is to be connected to the light-receiving plug terminal.

Abstract: An endoscopic system includes a sheath portion including an opening, a translucent balloon, an endoscope main body, and a display. The balloon includes a first index group having a plurality of balloon indices. Adjacent two of the plurality of balloon indices are different from each other. The balloon covers the opening and is configured to inflate and deflate. The endoscope main body is configured to be retracted into and projected from the opening. The endoscope main body is located inside the inflated balloon and is configured to observe an interior portion of a sinus. The display is configured to display an image obtained by the endoscope main body.

Abstract: 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.
