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.

摘要： The present invention provides an endoscopic treatment tool (1) that enables a technique such as tissue excision to be carried out more easily, and is provided with: a rod shaped cutting section (2); a wire (3), the cutting section (2) connected at the distal end thereof; and a sheath (4), into which the wire (3) is inserted. The cutting section (2) has a large diameter part (6) at its distal end. The treatment tool (1) further comprises a tubular distal member (9) which has a through hole (11A) along the axis and is attached to the distal end of the sheath (4), the diameter of the through hole (11A) being smaller than the outer diameter of the large diameter part (6). The tubular distal member (9) includes a rounded tip (11) which is exposed outside the sheath (4) and has a curving outer distal surface.

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.
