Abstract

Abstract An endoscope is provided with an operation unit provided with at least one operation member, an insertion section to be inserted in a human cavity, the operation unit being connected with a proximal end of the insertion section, a direction setting table provided at a distal end portion of the insertion section, the direction setting table adjusting a direction in which a distal end of a treatment instrument inserted through an instrument-inserting channel protrudes from a distal end portion of the insertion section of the endoscope, and an operation wire that moves along the axis thereof upon operation of the operation member, the operation wire being connected to the direction setting table so that the direction setting table is moved in accordance with operation of the operation member. With this structure, the distal end portion of the insertion section and the operation unit is electrically insulated.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 170 words
An endoscope, comprising: an operation unit provided with at least one operation member; an insertion section configured to be inserted in a human cavity, the operation unit being connected with a proximal end of the insertion section; a metal body member provided at a distal end portion of the insertion section; a metal direction setting table provided on the body member, the direction setting table adjusting a direction of a treatment accessory; an insulation member provided between the distal end of the insertion section and the body member so that the body member is insulated from the distal end of the insertion section; an insulating cap that covers the entire body member and the direction setting table except for an opening through which the treatment accessory protrudes to an exterior; an operation wire that is axially movable upon operation of the operation member, the operation wire being connected to the direction setting table so that the direction setting table is moved in accordance with an operation of the operation member.
Claim 2
Dependent Claim 170 words
An endoscope, comprising: an operation unit provided with at least one operation member; an insertion section configured to be inserted in a human cavity, the operation unit being connected with a proximal end of the insertion section; a metal body member provided at a distal end portion of the insertion section; a metal direction setting table provided on the body member, the direction setting table adjusting a direction of a treatment accessory; an insulation member provided between the distal end of the insertion section and the body member so that the body member is insulated from the distal end of the insertion section; an insulating cap that covers the entire body member and the direction setting table except for an opening through which the treatment accessory protrudes to an exterior; an operation wire that is axially movable upon operation of the operation member, the operation wire being connected to the direction setting table so that the direction setting table is moved in accordance with an operation of the operation member.
Claim 3
Dependent Claim 33 words
The endoscope according to claim 1 , said operation wire being surrounded by electrically insulating material, and said operation wire being electrically insulated with respect to the operation member of said operation unit.
Claim 4
Dependent Claim 66 words
The endoscope according to claim 1 , wherein said operation wire is connected to said operation member via a link mechanism, said link mechanism including a link member connected to said operation member, and a rod member connecting said link member and said operation wire, said rod member being fitted in and guided by a tube member so as to move in an axial direction thereof.
Claim 5
Dependent Claim 16 words
The endoscope according to claim 3 , wherein said tube member is formed of insulating material.
Claim 6
Dependent Claim 28 words
The endoscope according to claim 4 , wherein a proximal end of said wire is secured to said rod member, said rod member being made of insulating material.
Claim 7
Dependent Claim 48 words
The endoscope according to claim 3 , wherein an O-ring is provided on said rod member, said O-ring being deformed to have an elliptic shape, a rotational movement of said rod member with respect to said tube member being prevented due to the elliptic shape of said O-ring.
