【Effect of the invention】
As is apparent above, according to the present invention, the surgeon when inserting the rigid endoscope to the surgical unit, or when performing an operation work in the observation image under the rigid endoscope, wherein an observation image of the rigid endoscope rigid Since the observation image of the tip of the mirror can be observed by the same display means, the operator can easily grasp the positional relationship between the tip of the rigid mirror and the surgical site, and easily and surely move the rigid mirror to the surgical site. It can be guided, the workability of the operator can be improved, and fatigue can be reduced. Further, even when the surgical instrument is inserted in the vicinity of the tip of the rigid mirror, the surgical instrument can be easily guided to the vicinity of the tip of the rigid mirror by the observation image of the tip of the rigid mirror, which greatly increases the operation time. Can be shortened to.
