Abstract
An endoscope includes: an endoscope distal end rigid member; an objective optical system fixing frame; a moving frame; a wire unit including a rigid shaft portion; a wire unit connecting projection portion configured such that a flange having a diameter larger than the rigid shaft portion is screwed to a distal end face side; a first wire unit insertion hole through which a flange of the rigid shaft portion can pass in a state that screwing to the wire unit connecting projection portion is canceled; a lid member; a second wire unit insertion hole configured to be coaxial with a center axis of the first wire unit insertion hole, and through which the flange of the rigid shaft portion can pass; and a sealing member.
Claims5
An endoscope comprising:
- an endoscope distal end rigid member;
- an objective optical system fixing frame configured to hold an optical member configuring an objective optical system arranged on a distal end side inside a through-hole formed along a longitudinal axis of the endoscope distal end rigid member;
- a moving frame arranged on a holding frame freely movably forward and backward and configured to hold a moving lens such that the moving lens is moved forward and backward along an optical axis of the objective optical system;
- a wire unit including an operation wire, one end portion of which is connected to an operation lever, and a rigid shaft portion configured such that another end portion of the operation wire is integrally fixed to one end face side, a diameter of the rigid shaft portion being larger than the operation wire;
- a wire unit connecting projection portion provided protruding outward from an outer peripheral surface of the moving frame, and configured such that a flange provided on another end face side of the rigid shaft portion and having a diameter larger than the rigid shaft portion is screwed to a distal end face side;
- a first wire unit insertion hole provided on a holding frame protrusion portion including a proximal end face to which a distal end face of the wire unit connecting projection portion protruding outward from an outer peripheral surface of the holding frame comes into contact, and configured to be a through-hole through which a flange of the rigid shaft portion can pass in a state that screwing to the wire unit connecting projection portion is canceled;
- a lid member attached to the first wire unit insertion hole;
- a second wire unit insertion hole formed along the longitudinal axis of the endoscope distal end rigid member, configured to be coaxial with a center axis of the first wire unit insertion hole, and configured to be a through-hole through which the flange of the rigid shaft portion can pass in the state that screwing to the wire unit connecting projection portion is canceled;
- and
- a sealing member configured to seal the second wire unit insertion hole.
