Abstract: Provided are a surgical apparatus for an endoscope and an outer tube that ease limitation of the types of available medical instruments to improve convenience and improve operability. An outer tube, which passes through a body wall, is inserted into a body cavity, and guides an endoscope and a treatment tool into the body cavity, includes therein a slider that is an interlocking member that moves the endoscope and the treatment tool forward and backward in an interlocking manner. The slider is provided with a cylindrical pressure-contact member that is brought into pressure-contact with and coupled to an outer peripheral surface of the treatment tool. The pressure-contact member is formed of compressible foamed rubber having pores, and an oil component is held in the pores of the foamed rubber.

Abstract: An endoscope and a treatment tool are respectively inserted through an endoscope insertion passage and a treatment tool insertion passage of an overtube inserted into a body wall. A forward and backward movement operating part provided in a cable part provided to extend from a base end of an endoscope insertion part of the endoscope is arranged at a position adjacent to an operating part of the treatment tool. The forward and backward movement operating part includes a hook part having an opening, and a forward and backward movement operation of the endoscope can be performed by passing the index finger of a right hand gripping the treatment tool through the opening. Therefore, the forward and backward movement operation of the endoscope can be performed with the forward and backward movement operation of the treatment tool using only the one hand that operates the treatment tool.

Abstract: The overtube includes a slider within an overtube body, which guides an endoscope and a treatment tool. 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 includes a distal-end-side stopper and a base-end-side stopper that restrict the movable range of the slider. A length L from a coupling position of the endoscope to a distal end position of the overtube body and a length Ls from the coupling position of the endoscope to a distal end position of the endoscope are set to satisfy Ls≧L.

Abstract: An endoscope and an illuminator are safely placed in a body cavity without generating a noticeable postoperative scar. A method of placing medical insertion instruments into a body cavity includes a first step of inserting, into the body cavity through a first opening formed on a body wall, an endoscope together with a first illuminator; and a second step of inserting, into the body cavity through a second opening formed at a position different from the first opening, a second illuminator. Preferably, the method further includes a third step of pulling out the first illuminator from the first opening and inserting the first illuminator into the body cavity through a third opening formed at a position different from the first and second openings.

Abstract: An auxiliary thrust device includes a membrane, a carrier tube, and a drive cylinder. First and second insertion holes into which first and second torque wires are inserted are formed in a wire sheath. First and second gears are fixed to tip portions of the torque wires, which protrudes from a tip of the wire sheath, respectively. The first gear fixed to the first torque wire meshes with a spur gear portion of the drive cylinder, and the second gear connected to the second torque wire meshes with the first gear. Since the respective torque wires are inserted into one wire sheath and are bent in the same shape, a frictional force generated between the first torque wire and the inner surface of the wire sheath is substantially the same as that generated between the second torque wire and the inner surface of the wire sheath.

Abstract: A propulsion assembly includes a support sleeve for mounting on a tip device of an endoscope. An endless track device is supported on the support sleeve in an endlessly movable manner, for contacting a wall of a body cavity, for propulsion of the tip device relative to the body cavity. A drive sleeve drives the endless track device. First and second torque wire devices have proximal and distal end portions, the proximal end portion being rotated by a motor, the distal end portion actuating the drive sleeve. Plural helical windings of a first group constitute the first wire device, and are so wound as to increase tightness thereof upon moving the endoscope in a distal direction. Plural helical windings of a second group constitute the second wire device, and are so wound as to increase tightness thereof upon moving the endoscope in a proximal direction.
