- the operation knob 48 may be fixed using a friction generating member provided in the operation unit 13.
- a plurality of projections and depressions are formed on the rotation position of the operation knob 48 when the position of the guide wire 56 on the arbitrary side surface 13s of the exterior member 13g of the operation unit 13 is fixed.
- a friction generating member 13m which is a configured fixing means, is provided.
- the friction generating member 13m provided on the arbitrary side surface 13s of the operation unit 13 is used for friction, It can be carried out easily and reliably with a simple structure.
- the operation knob 48, the elevator drive mechanism 41, and the raising wire 30 are not provided with means for fixing the rotation of the operation knob 48, the rotation of the operation knob 48 can be fixed.
- the treatment instrument raising base 27 can be raised without changing the force with which the operation knob 48 is rotated.
- the place where the friction generating member 13m is provided is not limited to the place of the present embodiment, but may be a place where the rotation position of the operation knob 48 can be fixed when the position of the guide wire 56 is fixed. Any place may be provided.
- FIG. 12 is an enlarged perspective view of the gripping portion showing a modified example of the slip stopper formed on the gripping surface of the gripping portion of the operation knob of FIG.
- the outer peripheral surface of the gripping portion 48a is a gripping surface 48am when operated by the user, and the anti-slip 48as of the gripping surface 48am is as shown in FIG. It was formed by multiple protrusions!
- an anti-slip 48as is added to a plurality of protrusions, and a letter composed of the protrusions, for example, an endoscope with a guide wire fixing function, such as an "V" Characters like 148 may be formed.
- an endoscope with a guide wire fixing function such as an "V" Characters like 148
- the user uses the endoscope with the guide mechanism fixing function. This can be easily recognized with the finger of the user without looking at the endoscope.
- the character 148 formed on the gripping surface 48am is not limited to "V", and for example, "GW” indicating a guide wire may be used. Any character can be used as long as it allows the endoscope to be recognized. Further, the character 148 may be a guide wire size (inch) that allows the slit 27b of the treatment instrument elevator 27 to lock the guide wire 56, for example, “0.035” or “0.025”.
- the user recognizes that the endoscope is equipped with a guidewire fixing function during the operation of fixing the position of the guidewire 56. Therefore, the user mistakes the endoscope with a guide wire fixing function to use a conventional scope, and rotates the other operation knob to misunderstand that the guide wire 56 is fixed. Can be prevented.
- the character is not limited to an endoscope with a guide wire fixing function, and may be a character distinguishable from other endoscopes having no guide wire fixing function. .
- the convex character 148 is simply formed on the gripping surface 48am of the gripping portion 48a of the operation knob 48.
- the grip 48 of the operation knob 48 is formed in a color different from the color of the bending operation knob 35, as shown in FIG.
- the bending operation knob 35 is usually formed in black, but in this case, if the operation knob 48 is formed in a fluorescent color or the like, the user is temporarily in a dark laboratory. Even so, it can be easily recognized that the endoscope is an endoscope with a guide wire fixing function.
- the color of the grip portion 48a is not limited to an endoscope with a guide wire fixing function, and may be a color for recognizing an endoscope having no other guide wire fixing function. Absent.
- a guide wire fixing function is provided.
- the letter “V” 400 indicating the attached endoscope may be turned on so that the user can visually recognize it. Note that the letter “V” 400 is not limited to lighting, but may be blinking.
- FIG. 13 is a diagram showing a modification example in which the user recognizes that the endoscope has a guide wire fixing function using the monitor 4 of FIG.
- any character may be used as long as the character to be lit on the monitor 4 is a character that allows the user to recognize the endoscope with a guide wire fixing function.
- the lighting of the character 400 is not limited to the lower side of the monitor 4 but may be on the monitor screen 4a, and of course any position on the monitor 4 may be used.
- it is not limited to endoscopes with a guide wire fixing function, and it may be a display for recognizing other endoscopes. V. Needless to say!
- the treatment instrument raising base 27 is shown to be configured to have the function of the guide wire fixing means.
- the present invention is not limited to this, and the guide wire fixing means and the treatment A tool stand 27 may be provided separately.
- a guide wire fixing operation member for operating the guide wire fixing means may also be provided separately from the operation knob 48 to fix the operation position of the guide wire fixing operation member.
- the endoscope according to the present invention is useful for an endoscope that performs a medical act on the digestive tract and splenic bile duct system, and in particular, a treatment instrument in the splenic bile duct system and the like.
- This is suitable for an endoscope that can fix a guide wire for guiding the guide wire at a desired position.
