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： 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 attachment jig includes a cylinder portion at one end of which a ring portion for fixing a self-propelled device to an endoscope is provided, and a handle portion which is provided at the other end of the cylinder portion and is gripped so as to rotate the cylinder portion. An O ring is brought into press-contact with the outer periphery of an insertion section of the endoscope, such that the self-propelled device is fixed to the insertion section. When the handle portion is further turned, a thin-walled breaking portion is broken, and the ring portion is separated from the cylinder portion. When the handle portion is rotated in an opposite direction, the cylinder portion is taken out from the insertion section, while the ring portion remains in the fixed position.

摘要： An endoscope has a head assembly for entry in a body cavity. A guide apparatus for propulsion of the head assembly is provided, and includes a shaft sleeve, a support sleeve, a drive sleeve, drive gears, an endless track device, two intermediate gears, and a motor. Two wire devices are disposed to extend in an axial direction, have distal ends to which the intermediate gears are respectively secured, for transmitting rotation of the motor to the intermediate gears. In fail-safe control, if one of the wire devices is broken, the broken wire device is detected. When the broken wire device is detected, a limited mode is set for driving the endless track device with a normal one of the wire devices in limited performance relative to normal operation. In a preferred embodiment, the guide apparatus has a differential device and two brake devices.

摘要： An endoscope includes a head assembly having a first central axis for entry in a body cavity. In combination with the endoscope, a guide assembly includes a shaft sleeve having a lumen, for mounting on the head assembly therewith. An endless track device is supported around the shaft sleeve, for endlessly moving along the first central axis, for propulsion of the head assembly inside the body cavity.

摘要： A guide assembly for an endoscope has an elongated tube for entry in a body cavity. Plural endless belts move in an axial direction of the elongated tube in contact with a cavity wall of the body cavity, to propel the elongated tube. A driving device is engaged with a first belt surface of the belts, for rotating to drive the belts. A pressure roller has a smaller width than a width of the belts in a transverse direction crosswise to the axial direction, for pressing the belts by contacting a second belt surface reverse to the first belt surface, to apply tension thereto together with the driving device. A regulating projection is formed to project from the second belt surface and to extend in the axial direction, for contacting a side surface of the pressure roller in the transverse direction, to prevent lateral misalignment of the belts.

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.
