Abstract
An endoscope includes an insertion part to be inserted into a body, and first and second angle knobs that change a direction of a distal end of the insertion part. An angle knob attaching shaft is inserted into the first and second angle knobs. An angle knob locking member is engaged with a distal end of the angle knob attaching shaft via a pressing member. When the angle knob locking member is engaged with the angle knob attaching shaft, movement of the first and second angle knobs toward a distal end side of the angle knob attaching shaft is regulated.
Claims14
An endoscope including:
- an insertion part to be inserted into a body of an observation target;
- an angle knob that changes a direction of a distal end of the insertion part in accordance with rotational operation;
- and
- an angle knob attaching shaft that is inserted into a rotation center of the angle knob and that pivotally supports the angle knob rotatably, the angle knob being detached from the angle knob attaching shaft at a stage before use and being attached to the angle knob attaching shaft at the time of use,
- the endoscope comprising:
- an angle knob locking member that is attachably and detachably provided at a distal end portion of the angle knob attaching shaft and that regulates movement of the angle knob attached to the angle knob attaching shaft to a distal end side of the angle knob attaching shaft to prevent the angle knob from falling off,
- wherein the endoscope further comprises:
- a shaft part that is provided at one of the angle knob locking member and the angle knob attaching shaft;
- and
- an opening that is provided in the other of the angle knob locking member and the angle knob attaching shaft and into which the shaft part is inserted,
- the shaft part has a distal end provided with a frange whose cross section perpendicular to the shaft part is formed in a non-circular shape,
- the opening is formed in the same shape as the flange, and
- the angle knob locking member is attached to the angle knob attaching shaft by rotation around the shaft part after the flange penetrates the opening.
