Claims

[Scope of Claim for Utility Model Registration] (1) An objective aperture at the distal end for obtaining a field of view inside the bladder, an eyepiece provided at the base for observing the image obtained at the objective aperture, and an eyepiece provided near the base. A catheter, endoscope, forceps, etc. that is inserted into the forceps insertion port and protruded from the forceps projection port in a cystoscope having a forceps insertion port provided and a forceps protrusion port provided near the tip portion. observation operating tools,
An insertion length measuring device for reading the insertion length of the observation operation tool inserted, and a position display device for displaying the insertion length read by the insertion length measuring device side by side in the field of view of the eyepiece. Characteristic cystoscope. (2) The observation operation tool has a scale printed in advance on the side surface, and the insertion length measuring device prints the insertion length of the observation operation tool inserted through the forceps insertion port on the side surface of the observation operation tool. The cystoscope according to claim 1, which is characterized in that the cystoscope measures by optically detecting the graduated scale. (3) The observation operating tool is equipped with a magnetic scale formed in advance on the side surface, and the insertion length measuring device measures the length of the observation operating tool inserted through the forceps insertion port on the side surface of the observation operating tool. 2. The cystoscope according to claim 1, which measures the cystoscope by electromagnetically detecting a scale of a magnetic material. (4) The insertion length measuring device is characterized in that the insertion length of the observation operation tool inserted through the forceps insertion port is detected from the rotational speed of a roller pressed against a side surface of the observation operation tool. The cystoscope according to claim 1 of the patent registration claim.
