    Abstract: A distal end of an endoscope insertion passage of an overtube is provided with a fluid supply and discharge port. When an observation window of the endoscope insertion part inserted through the endoscope insertion passage is cleaned, an operator can set a distal end surface at a predetermined positioning position using a positioning mechanism, without extracting the endoscope insertion part from the endoscope insertion passage. A concave cleaning storage part that communicates with the fluid supply and discharge port is formed inside the endoscope insertion passage on the distal end side. Cleaning water is supplied from the fluid supply and discharge port to remove foreign matter from the observation window, and stored in the cleaning storage part, and then, the cleaning water stored in the cleaning storage part is suctioned from the fluid supply and discharge port.

    Abstract: An overtube to be inserted into a body wall is provided with an endoscope insertion passage and a treatment tool insertion passage, the treatment tool insertion passage is provided parallel to a reference axis of the overtube, and the endoscope insertion passage is provided obliquely to the reference axis. A slider, which is engaged with the endoscope and the treatment tool inserted through the respective insertion passages and causes the endoscope and the treatment tool to interlock with each other and move forward and backward, is arranged inside the overtube so as to be movable in a forward-backward direction of the overtube. An endoscope engagement part engaged with the endoscope in the slider is movable in an upward-downward direction, and moves upward and downward along the position of the oblique endoscope insertion passage together with the movement of the slider in the forward-backward direction.

    Abstract: A propulsion apparatus for an endoscope includes a propulsion assembly for mounting on a tip device of the endoscope, for propulsion in a body cavity. First and second wire devices are disposed to extend from the tip device in a proximal direction, having a coil winding, for rotating to drive the propulsion assembly. First and second motors are connected with proximal ends of respectively the first and second wire devices, for rotating the first and second wire devices. A timer is actuated if a speed difference between rotational speeds of the first and second motors becomes equal to or more than a reference speed value, for measuring an elapsed time. A break detector detects breakage of the first wire device if the elapsed time becomes equal to or longer than a predetermined time. A controller controls the first and second motors in response to an output of the break detector.

    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 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. F1>F2 is satisfied when a fixing force for fixing the endoscope-coupled part to the endoscope tool is defined as F1 and a fixing force for fixing the treatment tool-coupled part to the treatment tool is defined as F2.

    Abstract: A surgery system includes an overtube that has a distal end, a proximal end, and a longitudinal axis and holds a treatment tool and an endoscope so as to be movable forward and backward in a direction of the longitudinal axis. The overtube has an endoscope holding part that has an endoscope holding surface for holding the endoscope and allowing circumferential rotation of the endoscope about a central axis of the endoscope, and a treatment tool holding part that has a treatment tool holding surface for holding the treatment tool. The surgery system further includes an endoscope that is inserted into the overtube and has a held surface held by the endoscope holding surface. The endoscope has an orientation maintaining part that maintains the circumferential orientation of the endoscope even in a case where the overtube rotates around the longitudinal axis.

    Abstract: An overtube, which is punctured into a body wall and guides an endoscope and a treatment tool into a body cavity, includes an interlocking member that interlocks the forward and backward movements of the endoscope and the treatment tool with each other. The interlocking member is constituted of a first sleeve coupled to the endoscope, a second sleeve coupled to the treatment tool, and a coupling member having an elastic body, which couples the first sleeve and the second sleeve together. Accordingly, in a case where the stretching of the coupling member is small, the endoscope interlocks with the forward and backward movement of the treatment tool at a slow response, and in a case where the stretching of the coupling member is large, the endoscope interlock with the forward and backward movement of a treatment tool at a quick response.
