Patent ID: 11839355

Abstract:
There is an endoscope that allows operations for attaching and detaching the proximal end of a wire to and from an elevating operation mechanism to be easily performed, can reduce the influence of variations of the length of a soft part and the length of an operation wire, and can adjust an operating range of an elevating operation lever for an elevator. The endoscope includes: an operation unit that is provided with an operation member; an insertion unit that is provided on a distal end side of the operation unit and is to be inserted into an object to be examined; a treatment tool-elevator that is provided in a distal end part of the insertion unit; a rotating body that is disposed to be exposed to an outside of the operation unit and operates in conjunction with an operation of the operation member; a movable member that is attachably and detachably connected to the rotating body; a position adjustment member that is capable of adjusting a connection position of the movable member in a rotation direction of the rotating body; an elevating operation wire, of which a distal end side is connected to the treatment tool-elevator and a proximal end side is connected to the movable member and which causes the treatment tool-elevator to operate by being pushed or pulled according to an operation of the movable member; and a mounting member that is provided at a proximal end of the elevating operation wire and is attachably and detachably engaged with the movable member.
