[Industrial applications]

 The present invention relates to a cover-type endoscope apparatus capable of connecting an external connection portion of a cover endoscope to an external apparatus for a cover-less endoscope.

[0002]

[Prior art]

 In recent years, endoscopes have been widely used in the medical field and the like. When an endoscope used in the medical field is inserted into a living body, the observation window provided at the distal end of the insertion section may become dirty due to adhesion of dirt, mucus, etc. on the affected area, and it may not be possible to fully observe it. It For this reason, the endoscope is provided with an air / water supply function of supplying liquid to the observation window for cleaning or manually operating the operator's hand side to blow the remaining water to the air. In addition, this insufflation function is also used when insufflating the body cavity to make it easier to observe the observation site. This air supply and water supply are supplied via an air supply line and a water supply line.

In addition, an endoscope is provided with a suction conduit for sucking and discharging unnecessary dirt, mucus, and the like, and further, for collecting tissue with biopsy forceps, medical treatment with a treatment tool, and the like. In some cases, a forceps channel (treatment instrument channel) is provided so that the forceps can be performed.

In the endoscope used in the medical field as described above, the endoscope once used for a patient or the like is subjected to cleaning or sterilization treatment in order to reliably prevent an infectious disease and the like.

However, it takes time to completely clean and disinfect, not only the workability is poor, but also the use efficiency of the endoscope is reduced.

[0006] In particular, since each of the above-mentioned conduits is communicated with the outside of the body from the distal end opening opening into the body cavity of the patient via the conduit of the insertion portion, the distal end opening and the inside of the conduit are completely It had to be cleaned and detoxified, and the work was troublesome.

Therefore, recently, there is a so-called cover-type endoscope that covers the endoscope itself with an endoscope cover and discards the endoscope cover for each floor to simplify cleaning and disinfection after use. Has been adopted.

According to this cover-type endoscope, a conduit opening into the body cavity of the patient is provided on the side of the endoscope cover, and an observing means and an illuminating means not opening into the body cavity of the patient are provided on the endoscope side. By covering it with an endoscope cover, even if it is a very expensive video endoscope that uses illumination means and a solid-state image sensor (SID), the video endoscope does not become dirty after use, and By disposing of the endoscope cover, cleaning and disinfection can be simplified.

A so-called cover-type endoscope of this type is disclosed, for example, in Japanese Examined Patent Publication No. 2-54734 (US Pat. No. 4,646,722) or US Pat. No. 3,162,190.

[0010]
