摘要： There is provided an endoscope and an endoscope flexible section that can secure bending rigidity and have the resistance against high temperature-and-pressure steam during sterilization. The endoscope flexible section includes a spiral tube, a net-like tube, and an outer cover member. The spiral tube is formed by winding a belt-like member made of metal, in a spiral shape. The net-like tube is formed in an annular shape on the periphery of the spiral tube by braiding thin metal wires. The outer cover member is formed on the periphery of the net-like tube. In the outer cover member, a polyparaxylene resin layer is formed in a pattern on the periphery of a cover layer that covers the periphery of the net-like tube and is made of fluororubber. The polyparaxylene resin layer is a pattern of the plural rings that are disposed in a circumferential direction at predetermined intervals.

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 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： 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.
