Embodiment Construction

[0042] Next, an endoscope treatment tool 1 according to an embodiment of the present invention will be described with reference to the drawings.

[0043] Such as figure 1 As shown, the endoscope treatment instrument 1 of the present embodiment includes: a spring tube (sheath) 2; a front end support member 3 fixed on the front end of the spring tube 2; a pair of grasping members supported by the front end support member 3 4a, 4b; the operation part 5 provided at the root end of the spring tube 2; and the operation wire 6 connecting the operation part 5 and the grip members 4a, 4b.

[0044] Reference numeral 7 in the figure is a resin coating tube that covers the outer surface of the spring tube 2 . The spring tube 2 is formed by tightly winding a steel wire such as stainless steel in a helical shape. The spring tube 2 and the cover tube 7 have a constant outer diameter that can be inserted into a channel of an unillustrated endoscope.

Abstract

A treatment tool (1) for an endoscope is provided with: a sheath (2) having a longitudinal axis (A); a rotating shaft extending in an axial direction orthogonal to the longitudinal axis (A) of the sheath (2); a pair of gripping members (4a, 4b) pivotably connected to the rotating shaft extending in the axial direction; an operating wire (6) connected to the pair of gripping members (4a, 4b); and a plate including a bearing to which the rotating shaft is fit and an abutting section protruding outward in the radial direction of the sheath (2). The plate extends between the rotating shaft and the sheath (2).

Description

technical field [0001] The present invention relates to a treatment tool for an endoscope. Background technique [0002] There is known a treatment tool for an endoscope in which a front end treatment member as a biopsy forceps is openably and closably supported around a fulcrum on a front end support member fixed to the front end of a flexible sheath. Pair the pliers cup (for example, refer to Patent Document 1). [0003] The front end support member has gaps facing each other with a gap therebetween. A link mechanism for opening and closing the pliers cup is arranged in the gap. Through the forward and backward operation of the operating wire inserted in the flexible sheath, the link mechanism can be driven to make the pliers cup open and close in the shape of a mouth. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2002-58675 Contents of the invention [0007] The technical problem to be solved by t...
