    摘要： An endoscopic instrument includes: a high-frequency knife for carrying out incisional intervention; a wire having a distal end connected to the high-frequency knife; an outer sheath for allowing the wire to pass therethrough; a main body having a proximal end of the sheath fixed thereto; a first slider, capable of freely sliding on the main body, having the wire fixed thereto; at least a stopper projecting radially outward relative to the wire; a first abutment member making contact with the stopper and regulating distal sliding movement of the wire; and a projection-length-adjusting member, provided in the outer sheath, for regulating proximal sliding movement of the wire by making contact with the stopper. This configuration allows the high-frequency knife to be maintained at different projection lengths based on the stopper making contact with the first abutment member and the stopper making contact with the projection-length-adjusting member.

    摘要： The endoscope treatment tool 1 has a distal end member 3 which is installed in an endoscope. A connection member 4 is attached to the distal end member 3 in a freely rotatable manner. In the connection member 4, a portion which is supported by a cap 12 of the distal end member 3 is a second pivot shaft 15. A portion penetrating a supporting member 21 of a treatment portion 5 is a first pivot shaft 23. The first pivot shaft 23 is also a rotational axis of a pair of forceps members 22 provided in the treatment member 5. When the forceps members 22 are used, a coil sheath 6 is extended by an operation at the side of the proximal end. The connection member 4 rotates about the second pivot shaft 15, which is a fulcrum, and the treatment portion 5 moves forward beyond the cap 12. In accordance with the present invention, it is possible to resolve the difficulty of procedures by positioning the treatment portion in an appropriate location.

    摘要： An endoscope treatment tool includes: a cylindrical cap attached to an outer side of a distal-end section of an endoscope and having first and second radial directions intersecting each other; a treatment tool supported at an outer side of the cap in the first radial direction to be movable in the longitudinal direction; and a linear flexible coupling member coupling the treatment tool with the cap such that the grasper reaches a position where the grasper protrudes from a distal end of the cap. A swing section of the coupling member couples the cap with the treatment tool to allow relative movement in the second radial direction, and, in response to pressed forward in the longitudinal direction by the treatment tool, swings about a swing axis extending in the second radial direction while generating a tensile force and bending the treatment tool inward in the first radial direction.

    摘要： A high-frequency treatment instrument for performing a high-frequency treatment on a pathological lesion portion includes an elongated flexible sheath 2, a pair of arm portions 3A and 3B which is disposed in the sheath 2 so as to freely extend and retract, which is in a closed state in the sheath, and which is opened in a direction moving away from a center axial line of the sheath 2 when it protrudes from the distal end of the sheath 2, a linear treatment electrode which is connected to the distal end sides of the pair of arm portions and which is stretched between the arm portions when the pair of arm portions are opened, an operating wire (elongated extension member) which is disposed in the sheath 2 so as to freely extend and retract and the distal end of which is connected to the treatment electrode, and an operating portion, to which the proximal ends of the sheath and the operating wire are connected, and which operates the operating wire to extend and retract relative to the sheath 2. According to the invention, it is possible to facilitate a procedure by enabling a treatment on a target tissue without performing a curving operation of an endoscope.
