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： 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： If an instruction indicating advance is input, first and second motors are driven to rotate first and second torque wires. A rotary body is circulated by the rotation of the first and second torque wires, and a propelling unit advances. The first and second TGs detect the rotating speeds of the first and second torque wires. If disconnection of the first torque wire is detected by a disconnection detecting section, a motor control section stops driving of the first motor coupled to the disconnected first torque wire, and rotates the second motor coupled to the second torque wire that is not disconnected at a low speed to rotate the second torque wire at a low speed. Through the low-speed rotation of the second torque wire, the propelling unit advances at a low speed or retreats at a low speed.

摘要： A guide assembly for an endoscope includes a shaft sleeve, barrel sleeve, support sleeve and endless track device for propulsion by endlessly moving in an axial direction of an elongated tube. A rotation wheel is supported on the barrel sleeve, for driving the endless track device by rotating. An idler roller is supported on the support sleeve in a rotatable manner, for keeping the endless track device movable in cooperation with the rotation wheel. A small diameter portion is formed with two axial ends of the rotation wheel by decreasing a wheel diameter thereof along a wheel axis, for allowing leaving of the idler roller from the rotation wheel upon rotationally shifting the support sleeve around the barrel sleeve, so that the endless track device is released from tight contact therewith, and separated from the barrel sleeve in the axial direction with the support sleeve.
