摘要： An insertion assisting device includes a rotary body formed in a toroidal shape, and a support and drive unit that rotatably supports and rotates the rotary body. The support and drive unit has two supports, a first support and a second support. The first support is formed in a substantially cylindrical shape, and rotatably supports the rotary body. The second support is formed in a substantially triangular tubular shape, is arranged inside the first support, and supports driving gears that transmit a driving force to the rotary body. The second support is shorter than the first support, and is arranged so that front and rear end portions thereof are located inside front and rear end portions of the first support.

摘要： A self-propelled device nips an endless belt between a worm wheel and a driven roller. The endless belt is circulated by rotating the worm wheel, and thereby an insertion section of an endoscope advances and retreats inside a body cavity. The driven roller has a width larger than the worm wheel, and is provided with a pair of flanges at both ends. The worm wheel is disposed between the pair of flanges. When the endless belt is nipped between the worm wheel and the driven roller, the endless belt is deformed by the pair of flanges.

摘要： A propelling device includes a traveling body that rotates in a state of being brought into contact with an inner wall of an alimentary canal, an external cylinder around which the traveling body is wound, and a mounting cylinder on which a tip end portion of an endoscope is mounted. Three driven rollers are rotatably attached to the external cylinder. The traveling body is pinched between the driven rollers and driving gears. As the driving gears rotate, the traveling body travels in a circulating manner. A rotating shaft of the driven roller located at the center among the three driven rollers is held by a shaft hole that is made long in a gear arrangement direction in which the driving gears are disposed side by side.

摘要： An insertion assisting device includes a rotary body in the form of toroid, and a support and drive part for supporting the rotary body in a rotatable manner and rotating it. The support and drive part has an approximately cylindrical supporting member for supporting the rotary body in a rotatable manner. The rotary body is provided with a convex portion for increasing the thickness to improve the strength thereof. A concave portion having a shape corresponding to the shape of the convex portion is formed on a portion of a front end surface of the supporting member, which is made in contact with the convex portion. The concave portion prevents the rotary body from stopping rotating, which may be caused by point contact between the convex portion and the supporting member.

摘要： An insertion and extraction assisting device of an endoscope has a promotion unit attached on the front end side of the endoscope and a transmission section whose one end is connected to a promotion unit, and the other end is drawn along the endoscope, and an outside unit. The other end of the transmission section is connected to the outside unit, and rotational force or a turn signal from the outside unit is transmitted to the promotion unit, so that driving force is generated by the promotion unit. When the other end of the transmission section is connected to, the outside unit reads an ID code expressing a kind of the promotion unit and controls the rotational force or the turn signal to send to the promotion unit.

摘要： A cylinder portion is inserted into a gap fanned between an outer peripheral surface of a tip end rigid portion of an endoscope and an inner peripheral surface of a self-propelled device from the side of a tip end face of the tip end rigid portion. A ring portion is disposed at a front end side of the cylinder portion, and a handle portion is disposed at a rear end side thereof. A position regulating portion for receiving the tip end face of the tip end rigid portion to define an insertion position of the tip end rigid portion is disposed in the cylinder portion. In some instances, the self-propelled device moves to a fixed position on the tip end rigid portion, and is fixed thereto by the ring portion. The cylinder portion is separated from the ring portion, and pulled out from the tip end rigid portion.

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.
