Abstract:
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. A contact surface of the overtube body with a body wall is constituted of a wall surface member that serves as a rotation-preventing wall surface for preventing rotation in a rotational direction with an axial direction of the overtube body as a center.

Claim (Index 1):
An endoscopic surgical device comprising:\n an endoscope that observes the inside of a body cavity; a treatment tool that inspects or treats an affected part within the body cavity; an overtube that guides the endoscope and the treatment tool into the body cavity; and an exterior tube that fixes the overtube to an abdominal wall, wherein the overtube includes an overtube body that passes through a body wall and is inserted into the body cavity, a slider member provided in the overtube; and a sleeve member provided in the overtube; wherein the slider member has a first stopper and a second stopper which are provided separately from each other in a longitudinal axis direction of the overtube, the sleeve member is slidably located on a first path formed between the first stopper and the second stopper, the slider member has a first holder part configured to hold the endoscope and a second path through which the endoscope is inserted, the sleeve member has a third path through which the treatment tool is inserted, and the sleeve member comprises a second holding part configured to hold the treatment tool inserted through the third path, wherein the exterior tube comprises: an insertion part that covers the portion of the overtube body that passes through the body wall, a base end part that is provided on a base end side of the insertion part and has a larger external diameter than that of the insertion part, and an airtight valve that is provided at the base end part and maintains the airtightness with the overtube body, and wherein a plurality of transverse grooves along a circumferential direction are formed in an axial direction in an outer peripheral surface of the insertion part, the transverse grooves have a distal end-side wall surface and a base-end-side wall surface, and an inclination angle of the distal end-side wall surface with respect to a radial direction of the insertion part is made smaller than an inclination angle of the base-end-side wall surface with respect to the radial direction of the insertion part.
