摘要： A ligating apparatus includes a clip, a clip connecting member, a clip holding member, an operating wire, an inner sheath member, an outer sheath member and first and second movement restricting portions. The clip ligates a body tissue with arm portions. The clip connecting member connects to a clip base portion. The clip connecting member is inserted through the clip holding member. The operating wire connects to the clip connecting member. The inner sheath member encloses the operating wire to support the clip holding member. The outer sheath member covers an outer periphery of the inner sheath member and freely advances and retreats. The outer sheath member advances and/or retreats to change the degree of opening of the arm portions. The first movement restricting portion restricts the inward movement of the clip holding member. The second movement restricting portion restricts the outward movement of the clip holding member.

摘要： A ligating-apparatus includes a clip, an operating wire, an inner sheath member and an outer sheath member. The clip ligates a body tissue with arms. The operating wire pulls the clip. The inner sheath member encloses the operating wire to support a clip holding member. The outer sheath member advances and retreats while covering the inner sheath member. The outer sheath member changes the degree of opening of the arms by causing each arm to abut on an inner peripheral surface thereof. A pair of arms includes first arm portion and a second arm portion connected continuously to the first arm portion via a bending portion. When the bending portion abuts against an inner peripheral surface end portion of the outer sheath member, the second arm portion is arranged at an inner side in a direction of a radius from an inner peripheral surface of the outer sheath member.

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 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.
