Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope apparatus which can be selectively connected to an endoscope used with an overtube and an endoscope used without an overtube. Regarding

[0002]

2. Description of the Related Art Conventionally, by inserting an elongated insertion portion into a body cavity, the organ inside the body cavity can be observed and, if necessary,
2. Description of the Related Art Endoscopes that can perform various kinds of treatments and treatments using a treatment instrument inserted in a treatment instrument channel are widely used. Also,
Also in the industrial field, industrial endoscopes capable of observing and inspecting scratches and corrosion inside boilers, turbines, engines, chemical plants and the like are widely used.

Endoscopes used for examinations, treatments, treatments, etc. in body cavities are washed between cases, or are washed together after the endoscopic examination to prevent infections caused by the endoscopes. I was trying to do it.

In the endoscope, each endoscope is connected to a washing device having a liquid feed pump to feed the washing liquid into the pipe line for washing, or the endoscope is ultrasonicated. The cleaning is performed by immersing in an cleaning solution in an ultrasonic cleaning tank having an oscillating device and ultrasonically vibrating the cleaning solution. However, when washing an endoscope used for a patient with hepatitis or the like, a considerable amount of time was required to ensure sterilization.

For this reason, recently, an observation optical system and an illumination optical system are provided so that the overtube can be attached to the endoscope each time an endoscopic examination is performed, or the overtube can be attached without increasing the outer diameter. The system is constructed with a semi-circular cross section, and an overtube with a flow path system is attached to the endoscope to perform an endoscopic inspection.After the inspection, the overtube attached to the endoscope is replaced with a new one. There has been proposed a disposable overtube which can be replaced with another one so that the cleaning time between cases can be eliminated and endoscopy can be performed.

[0006]

However, if a disposable overtube is attached to all endoscopic examinations of a patient suspected of having an infectious disease and a patient having no possibility of having an infectious disease, it may cause a financial problem. There is a possibility that the problem of adverse effects on the environment due to industrial waste may occur.

The present invention has been made in view of the above circumstances, and an endoscopic device capable of realizing the most efficient endoscopic medical treatment by being selectively used depending on the presence or absence of an infectious disease of a patient and the purpose of use. Is intended to provide.
