Embodiment Construction

[0027] Below, refer to Figure 1 ~ Figure 5 A treatment tool for an endoscope according to the first embodiment of the present invention will be described.

[0028] Such as figure 1 As shown, the treatment tool for endoscope in this embodiment, that is, the treatment tool 1 includes: a treatment part 10 for treating tissue in a body cavity; an operating part 20 for operating the treatment part 10; a connecting part 30 It is used to connect the treatment part 10 and the operation part 20; and a long-length insertion part 40 for inserting into a body cavity.

[0029] The treatment section 10 is configured such that a pair of forceps members composed of a first forceps member 11 and a second forceps member 12 is supported by a forceps rotation shaft 13 so as to be relatively freely rotatable. The forceps rotation shaft 13 is supported by a cover (cover member) 14 arranged to sandwich the forceps members 11 and 12.

[0030] The operation portion 20 includes a main body 21 to which the i...

Abstract

A treatment tool (1) for endoscope includes a pair of forceps members (first forceps members (11) and second forceps member (12)) supported by a forceps rotation axis such that they can rotate relatively, an operation part for performing an open-close operation of the pair of forceps members, an operation wire that connects the pair of forceps members and the operation part, an insertion part which the operation wire is inserted into, a cover member (14) that secures the forceps rotation axis to the insertion part, a connection member including a link rotation axis, provided at a distal-end part of the operation wire, and a pair of link members (first link member (35) and second link member (36)), first end parts of each being rotatably connected via respective rotation axis members (38, 39) to a proximal-end part of each of the pair of forceps members, and second end parts of each being rotatably connected to the link rotation axis. The cover member (14) includes grooves (14A, 14B) formed such that, by engaging with end parts of the rotation axis members, they restrict the movement of the rotation axis members in a direction of approaching the axis (X1) of the operation wire.

Description

Technical field [0001] The present invention relates to a treatment tool for an endoscope used by being inserted into a body cavity through an endoscope. This application is based on Japanese Patent Application No. 2010-124664, which was filed in Japan on May 31, 2010, as the basis for claiming priority, and its content is cited here. Background technique [0002] Conventionally, there has been known a treatment tool for an endoscope (hereinafter, simply referred to as "treatment tool") for performing various manipulations on tissues in the body cavity of a patient or the like by inserting it into a body cavity through an endoscope. [0003] As an example of a treatment tool, a forceps described in Patent Document 1 is known. In this pliers, a pair of pliers members supported to be relatively rotatable with each other via a rotation shaft are provided at the tip. [0004] A pair of forceps members are connected to the operating part on the hand side by operating wires. Two link me...
