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.
摘要翻译：自推进装置的推进装置安装在电子内窥镜的插入部的前端部。推进单元包括设置在其前部的进给辊。在每个进给辊上，带的一端被卷绕。每个进料辊后面都设有卷绕辊和蜗轮。当蜗轮旋转时，皮带从进料辊中拉出，卷绕到卷绕辊上。皮带在与体腔的内壁接触的同时移动，因此对插入部的前端部产生推进力。当皮带和内壁之间的接触不足时，气球被充气以将皮带压靠内壁。

摘要： An endoscope includes a section of an elongated tube for imaging an object by entry in a body cavity. For use with this, a guide assembly includes a shaft sleeve for mounting on the elongated tube by reception thereof. 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 drive sleeve is contained in the housing sleeve, for driving the endless belts. Side projections as side rail portions are disposed on the housing sleeve, for covering lateral side portions of each of the endless belts at least partially, to keep the endless belts slidable. Preferably, the side projections cause curving of a center portion of the endless belts outwards with respect to a transverse direction.

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： 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.

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.
