    摘要： Apparatus is provided for use with a biologically-compatible-fluid pressure source, the apparatus including an elongate carrier, adapted to be inserted through a proximal opening of a body lumen, and a piston head coupled to a distal portion of the carrier. The piston head is adapted to form a pressure seal with a wall of the lumen after the carrier has been inserted into the lumen, and to be advanced distally through the body lumen in response to pressure from the fluid pressure source. The apparatus is configured to facilitate distal advancement of the piston head by facilitating passage of fluid out of the lumen from a site within the lumen distal to the piston head. The apparatus additionally includes an optical system, coupled to the carrier in a vicinity of the distal portion, the optical system having distal and proximal ends. The optical system includes an image sensor, positioned at the proximal end of the optical system; an optical member having distal and proximal ends, and shaped so as to define a lateral surface, at least a distal portion of which is curved, configured to provide omnidirectional lateral viewing; and a convex mirror, coupled to the distal end of the optical member, wherein the optical member and the mirror have respective rotational shapes about a common rotation axis.

    摘要： An endoscope includes an insertion section including an insertion main body extended along a longitudinal axis and being inserted into a lumen, an operation section provided to a proximal direction side of the insertion section, and an attachment unit including a fin portion spirally extended along the longitudinal axis and provided to an outer peripheral direction side of the insertion section to be rotatable about the longitudinal axis with respect to the insertion main body. The endoscope includes a rotary gear rotating about a gear axis to rotate the attachment unit about the longitudinal axis, and a built-in extended member extended through an inside of the insertion main body and an inside of the operation section from a distal end portion of the insertion section along the longitudinal axis. The insertion main body includes a partition member separating the built-in extended member from the rotary gear.

    摘要： An endoscope (10) 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 (51) for mounting on the elongated tube by reception thereof. A housing sleeve (32, 72, 82, 102) is supported around the shaft sleeve. Three endless belts (30, 90, 110) are secured to the housing sleeve, for endlessly moving in an axial direction (A) of the elongated tube, and propelling the elongated tube by contacting a cavity wall of the body cavity. A drive sleeve (52) is contained in the housing sleeve, for driving the endless belts. Side projections (33c, 33d, 73c, 73d, 83c, 83d) as side rail portions are disposed on the housing sleeve, for covering lateral side portions (37) 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 (36) of the endless belts outwards with respect to a transverse direction.

    摘要： PROBLEM TO BE SOLVED: To provide an endoscope mounting fixture capable of reducing burdens on a patient while obtaining sufficient propulsive force.SOLUTION: A body 40 of a self-propellable apparatus is mounted on an insert section of an endoscope. On a front end part of the body 40, a feeding roller 56 around which a belt 42 with an end is wound is provided. A balloon 43 is provided behind the feeding roller 56, and a worm wheel 57 and a winding roller 59 are provided behind the balloon 43. When the worm wheel 57 is rotated, the belt 42 is drawn out from the feeding roller 56 and wound up onto the winding roller 59 through the outer side of the balloon 43. Thus, propulsive force is supplied to the insert section. When an outer diameter of the body 40 is small and sufficient propulsive force cannot be obtained, the balloon 43 is inflated.
