きさ等を計測し得る内視鏡装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an endoscope device that can measure the distance to a target site such as an affected area and the size of the target site.
近年、生体腔内の診断、治療等において内視鏡装置が広

対象物の大きさ等を知ることが、診断及び治療において
必要不可欠なものとなって来ている。In recent years, endoscope devices have been widely used in diagnosis, treatment, etc. inside living body cavities. In this case, knowing the distance to the target site, the size of the target object, etc. has become essential for diagnosis and treatment.

しい方式をもった内視鏡装置の出現が強く要望されてい
た。Conventional endoscope devices that meet this demand use a complex optical system to determine the optical position of the lens system and the imaging magnification at a predetermined object relationship. They either determined the distance and the size of the target area, or incorporated special detectors or means for distance measurement. Therefore, the former type of endoscope device can be expected to have high measurement accuracy, but the latter type has the problem of being structurally complex and increasing cost. The biggest drawback is that complicated means such as an optical system or a detector to determine distance and size must be incorporated into the endoscope insertion section, which makes the insertion section too large and reduces operability. However, the diagnostic area is also limited. As a result, there has been a strong demand for an endoscope device with a new method.

することを目的とする。The present invention was made in view of the above-mentioned circumstances, and it is possible to improve the distance to the target site and the size of the target site by modifying only a part of the endoscope without enlarging the endoscope insertion section. The purpose of the present invention is to provide an endoscope device that can measure the following.

The present invention is based on the provision of a surveying light beam projection means.
