Abstract:
1. A treatment instrument for endoscope comprising: a first forceps member comprising a first electrode part, and a second forceps member; a forceps rotation axis that supports the first forceps member and the second forceps member, such that the first forceps member and the second forceps member are capable of rotating about the forceps rotation axis relative to each other; a first link member and a second link member; a first link member rotation axis that supports the first forceps member and the first link member, and a second link member rotation axis that supports the second forceps member and the second link member, wherein the first link member and the second link member make the first forceps member and the second forceps member open and close; a link support member supporting the first link member and the second link member in a state where the first link member and the second link member are separated at a predetermined interval at least when the first forceps member and the second forceps member are closed; an operation part connecting to the link support member, the operation part opening and closing the first forceps member and the second forceps member by moving the first link member and the second link member; and a first power supply wire, one end thereof being connected to the first electrode part by being attached to the forceps rotation axis, and another end thereof being connected to a current supply means providing a current to the first electrode part, the first power supply wire disposed in a separated space formed according to the predetermined interval between the first link member and the second link member by the link support member, wherein a displacement of the first link member rotation axis and the second link member rotation axis toward the separated space is restricted by the first power supply wire.
