a treatment tool including an operation unit in a proximal end of a rod-shaped insertion part; and
an outer tube including an endoscope insertion path in which the insertion part of the endoscope is insertable in a back-and-forth movable manner, and a treatment tool insertion path in which the insertion part of the treatment tool is insertable in a back-and-forth movable manner,
wherein the insertion part of the endoscope inserted in the endoscope insertion path is configured to be movable back and forth with a predetermined allowance amount, in interlock with a back-and-forth movement of the insertion part of the treatment tool inserted in the treatment tool insertion path.
2. The endoscopic surgery device according to claim 1, wherein
a back-and-forth movement amount of the insertion part of the treatment tool with respect to the outer tube is 60 mm or more, and
the allowance amount in an axial direction of the insertion part of the treatment tool with respect to the insertion part of the endoscope is 10 mm to 30 mm.
3. The endoscopic surgery device according to claim 1, further comprising
a coupling member which is disposed inside the outer tube and configured to couple the insertion part of the endoscope and the insertion part of the treatment tool, wherein
the coupling member includes:
a first movable object which includes an endoscope holding member that holds the insertion part of the endoscope and is configured to move back and forth in an integral manner with the insertion part of the endoscope; and
a second movable object which includes a treatment tool holding member that holds the insertion part of the treatment tool and is configured to move back and forth in an integral manner with the insertion part of the treatment tool, and
one of the first movable object and the second movable object is configured to move back and forth with the allowance amount in interlock with a back-and-forth movement of another one of the first movable object and the second movable object.
4. The endoscopic surgery device according to claim 3, wherein
the first movable object is held to the outer tube through a first friction force, and
the second movable object holds the insertion part of the treatment tool through a second friction force larger than the first friction force, is held to the first movable object through a third friction force less than the first friction force and is slid by the allowance amount with respect to the first movable object.
The claims below are in addition to those above.
