摘要： A propelling unit of a self-propellable apparatus is attached to a front end portion of an insert section of an electronic endoscope. The propelling unit includes feeding rollers disposed at its front. On each feeding roller, one end of a belt is wound. A winding roller and a worm wheel are provided behind each feeding roller. When the worm wheel rotates, the belt is drawn out from the feeding roller, and wound up onto the winding roller. The belts move while making contact with an interior wall of a body lumen, and hence produce propulsive force to the front end portion of the insert section. When the contact between the belts and the interior wall is insufficient, a balloon is inflated to press the belts against the interior wall.

摘要： An endoscope has an elongated tube for entry in a body cavity. A guide assembly includes a shaft sleeve for mounting on the elongated tube. A housing sleeve is supported around the shaft sleeve. Three endless belts are secured to the housing sleeve, for endlessly moving in an axial direction of the elongated tube, and propelling the elongated tube by contacting a cavity wall of the body cavity. A driving device is contained in the housing sleeve, for driving the endless belts. Three curved walls constitute the housing sleeve, and support the endless belts movably and in a transversely curved state. Each of the endless belts includes an upper belt run, curved by the curved walls convexly outwards, for contacting the body cavity. A lower belt run is disposed inside, and tensioned between the driving device and the belt rollers.

摘要： A ligating apparatus includes a clip, a clip connecting member, a clip holding member, an operating wire, an inner sheath member, an outer sheath member and first and second movement restricting portions. The clip ligates a body tissue with arm portions. The clip connecting member connects to a clip base portion. The clip connecting member is inserted through the clip holding member. The operating wire connects to the clip connecting member. The inner sheath member encloses the operating wire to support the clip holding member. The outer sheath member covers an outer periphery of the inner sheath member and freely advances and retreats. The outer sheath member advances and/or retreats to change the degree of opening of the arm portions. The first movement restricting portion restricts the inward movement of the clip holding member. The second movement restricting portion restricts the outward movement of the clip holding member.

摘要： A ligating-apparatus includes a clip, an operating wire, an inner sheath member and an outer sheath member. The clip ligates a body tissue with arms. The operating wire pulls the clip. The inner sheath member encloses the operating wire to support a clip holding member. The outer sheath member advances and retreats while covering the inner sheath member. The outer sheath member changes the degree of opening of the arms by causing each arm to abut on an inner peripheral surface thereof. A pair of arms includes first arm portion and a second arm portion connected continuously to the first arm portion via a bending portion. When the bending portion abuts against an inner peripheral surface end portion of the outer sheath member, the second arm portion is arranged at an inner side in a direction of a radius from an inner peripheral surface of the outer sheath member.

摘要： A guide assembly of a self-propelled type for an endoscope having an elongated tube for entry in a body cavity is provided. First and second self-propelled units are secured to a steering device provided in the elongated tube, arranged in an axial direction of the elongated tube, the second self-propelled unit receiving force for driving from an external drive source. A flexible connector connects the second self-propelled unit to the first self-propelled unit and transmits the force applied to the second self-propelled unit to the first self-propelled unit. Preferably, the connector includes at least two coil springs having diameters different from one another, and combined in such a multi layer form that winding directions thereof are opposite to one another. The force is torque in a rotational direction about an axis of the axial direction.

摘要： An insertion path securing apparatus includes a bending-insertion assisting instrument and a sheath tube that includes a first lumen where the bending-insertion assisting instrument is inserted. The bending-insertion assisting instrument includes a bendable tip bending portion, an intermediate extension portion being connected to the tip bending portion, and a bending operation portion being disposed at a base end of the intermediate extension portion. The state of the intermediate extension portion can be selectively switched to a variable-shape state where the bent shape of the intermediate extension portion can be freely changed and a shape retaining state where the bent shape of the intermediate extension portion is retained. The sheath tube includes a tube-like insertion portion of which the state can be selectively switched to a variable-shape state and a shape retaining state, and an operation portion that is disposed at a base end of the tube-like insertion portion.
