Abstract: Provided is an endoscopic surgical device and an overtube with which a surgeon can easily obtain a desired image and in which operability is high. The overtube includes a slider within an overtube body, which guides an endoscope and a treatment tool into a body cavity. An endoscope-coupled part and a treatment tool-coupled part are provided inside the slider, and the slider has a dead zone where the forward and backward movement of either the endoscope or the treatment tool does not interlock with the movement of the other and a sensing zone where the forward and backward movement of either the endoscope or the treatment tool interlocks with the movement of the other. The overtube body is configured to allow the treatment tool to rotate around an axis thereof without changing the positional relationship of the endoscope and the treatment tool with respect to the overtube body.

Abstract: An object of the present invention is to provide an endoscopic surgery device and an outer tube, capable of easily obtaining an image desired by an operator to facilitate treatment as well as of performing minimally invasive surgery. In the endoscopic surgery device and the outer tube, an endoscope and a treatment tool are inserted into a body cavity through an outer tube. The outer tube is provided with a built-in slider. The slider is provided so as to be axially movable in the outer tube body. The endoscope and the treatment tool, inserted into the outer tube, are held by the slider. Moving the treatment tool allows endoscope to be moved in conjunction with the movement of the treatment tool.

Abstract: This endoscopic surgical device includes: an endoscope; a treatment tool; and a mantle tube. The inside of the mantle tube is partitioned by a partition wall member provided with an endoscope guide groove and a treatment-tool guide groove, to form an endoscope insertion passage and a treatment-tool insertion passage. An endoscope fixation tool and a treatment-tool fixation tool are respectively disposed inside the endoscope guide groove and the treatment-tool guide groove. The endoscope fixation tool advances and retracts in conjunction with the endoscope insertion part inserted through the endoscope insertion passage. The treatment-tool fixation tool moves in conjunction with the treatment-tool insertion part inserted through the treatment-tool insertion passage. When a coupling ring externally fitted to the partition wall member interlocks the endoscope fixation tool with the treatment-tool fixation tool, the endoscope insertion part also moves in conjunction with the advancement and retraction of the treatment-tool insertion part.
