Abstract: Provided is an endoscopic surgical device and an overtube with which a surgeon can easily obtain a desired image and operability is high. The overtube includes a slider inside the overtube body that guides an endoscope and a treatment tool into a body cavity, the first valve member provided in the endoscope insertion passage, and the second valve member provided in the treatment tool insertion passage. F1>F3 and F2>F3 are satisfied when a fixing force for fixing the slider to the endoscope is defined as F1, a fixing force for fixing the slider to the treatment tool is defined as F2, and a frictional force that receives from the first valve member when the endoscope moves forward and backward is defined as F3.

Abstract: An assist assembly for propulsion of a tip device of an endoscope in a body cavity includes an attachment sleeve and a support sleeve. A deformable circulation device is disposed to extend over inner and outer surfaces of the support sleeve, for endlessly moving in an axial direction of the tip device. Plural rollers are disposed on the support sleeve in a rotatable manner, for pressing an inner surface of the circulation device. An alignment projection is formed on the inner surface of the circulation device to project at a height L1. A location offset prevention groove is formed in the rollers at a depth L2, for receiving the alignment projection, and satisfying a condition L1≧L2, to prevent location offset of the circulation device from the rollers. Drive wheels tension the circulation device in cooperation with the rollers by deforming the alignment projection in the location offset prevention groove.

Abstract translation: 用于在体腔内推动内窥镜的尖端装置的辅助组件包括附接套筒和支撑套筒。 可变形循环装置设置成在支撑套筒的内表面和外表面上延伸，以在尖端装置的轴向方向上不停地移动。 多个辊以可旋转的方式设置在支撑套上，用于按压循环装置的内表面。 在循环装置的内表面上形成一个高度为L1的突起。 在辊的深度L2处形成位置偏移防止槽，用于接收对准突起，并且满足条件L1≥L2，以防止循环装置与辊的位置偏移。 驱动轮通过使位置偏移防止槽中的对准突起变形而与辊协作地张紧循环装置。
