Abstract

Abstract A densely wound coil and a wire which passes through the coil are inserted into a flexible part which has a flexibility. The coil which is fixed in the vicinity of a distal end of the wire has a proximal end thereof which is regulated in movement toward a rearward side by a stopper. The wire which extends rearward from the proximal end of the coil has a proximal end thereof which is drawn or pulled toward the rearward side by angular movement of an adjustment knob which is provided in the vicinity of a forward end of an operation part. By this traction, a compressive force is relatively applied to the coil to make flexibility of the coil changeable. Indicia associated with the adjustment knob alerts the user to the level of flexibility to which the adjustment knob is moved.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 107 words
An endoscope comprising: an elongated insertion part provided with a flexible part which has flexibility with respect to bend; an operation part formed in a vicinity of a proximal end of said insertion part, and provided with a grip for gripping by an operator; a flexibility varying member arranged within said flexible part, and varying in flexibility with respect to curvature; a flexibility modifying operation member provided in said operation part, for performing an operation to vary a flexibility of said flexibility varying member; and a notification mechanism for notifying to a user, levels of said flexibility corresponding to the operation of said flexibility modifying operation member.
Claim 2
Dependent Claim 107 words
An endoscope comprising: an elongated insertion part provided with a flexible part which has flexibility with respect to bend; an operation part formed in a vicinity of a proximal end of said insertion part, and provided with a grip for gripping by an operator; a flexibility varying member arranged within said flexible part, and varying in flexibility with respect to curvature; a flexibility modifying operation member provided in said operation part, for performing an operation to vary a flexibility of said flexibility varying member; and a notification mechanism for notifying to a user, levels of said flexibility corresponding to the operation of said flexibility modifying operation member.
Claim 3
Dependent Claim 22 words
An endoscope according to claim 1, wherein said notification mechanism is a notification mechanism for providing a visual notification to a user.
Claim 4
Dependent Claim 24 words
An endoscope according to claim 2 wherein said notification mechanism notifies a level of the flexibility by light emission of a light emitting element.
Claim 5
Dependent Claim 23 words
An endoscope according to claim 2, wherein said notification mechanism displays a level of flexibility onto a monitor which displays an endoscope image.
Claim 6
Dependent Claim 25 words
An endoscope according to claim 4, wherein said level which is displayed on said monitor is within a given display region of said endoscope image.
Claim 7
Dependent Claim 26 words
An endoscope according of claim 4, wherein said level which is displayed on said monitor is outside of a given display region of said endoscope image.
Claim 8
Dependent Claim 32 words
An endoscope according to claim 2, wherein, when an image which is displayed on said monitor is photographed on a film, said level which is displayed on said monitor is not photographed.
Claim 9
Dependent Claim 56 words
An endoscope according to claim 1, wherein said flexibility modifying operation member is movable and said notification mechanism is a mark which indicates a position occupied by said flexibility modifying operation member, and said mark notifies a level of flexibility of said flexibility varying member which corresponds to a position of said flexibility modifying operation member.
Claim 10
Dependent Claim 46 words
An endoscope according to claim 1, wherein said flexibility modifying operation member is a substantially cylindrical-shaped, rotatable operation knob, and said notification mechanism has a surface configuration in a peripheral direction of said operation knob to present different configurations, each representing a different level of flexibility.
Claim 11
Dependent Claim 51 words
An endoscope according to claim 1, wherein said flexibility modifying operation member is a substantially cylindrical-shaped, rotatable operation knob, and said notification mechanism indicates a level flexibility of said flexibility varying member from a position in a peripheral direction of a lever, by said lever which extends from said operation knob.
Claim 12
Dependent Claim 21 words
An endoscope according to claim 1, comprising a flexibility detection sensor for detecting a value of flexibility of said flexible part.
Claim 13
Dependent Claim 25 words
An endoscope according to claim 1, comprising a correction mechanism for correcting levels of said flexibility corresponding to operation of said flexibility modifying operation member.
Claim 14
Dependent Claim 20 words
An endoscope according to claim 2 wherein said notification mechanism notifies a level of the flexibility by generating a sound.
Claim 15
Dependent Claim 14 words
An endoscope according to claim 13, wherein said notification mechanism generates a click sound.
