Abstract: An endoscope insertion part of an endoscope and a treatment tool insertion part of a treatment tool are insertable through an overtube inserted into a body wall, and a slider is provided for moving the endoscope insertion part and the treatment tool insertion part forward and backward in an interlocking manner. An operating part of the treatment tool includes a guide member that guides a cable part so as to be movable forward and backward in an axial direction so that the cable part of the endoscope is kept from being separated from the surface of the operating part beyond a fixed distance. Accordingly, the cable part can be reliably held down by an index finger of a right hand gripping the operating part, and, the operation of the operating part and the movement operation of the endoscope insertion part can be performed with only a right hand.

Abstract: A self-propelling device includes a turning unit and a supporter. The supporter includes a first support sleeve, a second support sleeve and a cover formed respectively cylindrically. A drive wheel is secured to the first support sleeve in a rotatable manner. A pair of follower rollers are secured to the second support sleeve together. The cover is fitted on an outer surface of the second support sleeve externally, and disposed in the turning unit together with the second support sleeve. The turning unit is pressed by the follower rollers to the drive wheel. When the drive wheel rotates, the turning unit is circulated around the second support sleeve in a longitudinal direction of the first support sleeve. An inner wall of a body cavity will not be damaged, as the follower rollers are covered by the cover and do not appear externally even if the turning unit breaks.

Abstract: An electronic endoscope system is composed of an electronic endoscope, a light source apparatus, and a temperature converter. The electronic endoscope has a CMOS sensor in a distal portion of an insert section to be inserted into a patient's body cavity. Illumination light from the light source apparatus is applied to the body cavity through the distal portion. The temperature converter obtains an average pixel value of an optical black (OB) region out of an imaging signal from the CMOS sensor, and converts the average OB pixel value into a temperature of the CMOS sensor on a frame-by-frame basis with the use of data in a temperature conversion table. The table represents a relationship between the average OB pixel value and the temperature of the CMOS sensor. Light quantity of the illumination light is adjusted in accordance with the temperature of the CMOS sensor to prevent deterioration of image quality.

Abstract: The overtube includes a slider within an overtube body, which guides an endoscope and a treatment tool into a body cavity. An endoscope-coupled part and a treatment tool-coupled part are provided inside the slider, and the slider has a dead zone where the forward and backward movement of either the endoscope or the treatment tool does not interlock with the movement of the other and a sensing zone where the forward and backward movement of either the endoscope or the treatment tool interlocks with the movement of the other. A contact surface of the overtube body with a body wall is constituted of a wall surface member that serves as a rotation-preventing wall surface for preventing rotation in a rotational direction with an axial direction of the overtube body as a center.
