Description of the Related Art When performing an inspection diagnosis or an operation under observation with an endoscope, the outer surface of an objective lens of an endoscope inserted and installed in a body cavity is liable to be fogged or stained with blood, water spray, smoke or the like. As a result, the viewing field often deteriorates. Conventionally, in order to solve this, a nozzle is installed near the objective lens at the tip of the endoscope, and water and air are supplied to the outer surface of the objective lens for cleaning.

る。Generally, a water / air supply channel is formed in the endoscope main body, and water / air is supplied through this channel. In the endoscope apparatus disclosed in Japanese Patent Laid-Open No. 6-189893, The endoscope insertion portion is covered with a pipe-shaped sheath, a space is formed between the sheath and the endoscope insertion portion, and the space here is used as a water supply channel.

In the endoscope device disclosed in Japanese Patent No. 3, the endoscope insertion portion is covered with a pipe-shaped sheath, and a gap formed between the sheath and the endoscope insertion portion serves as a water supply channel. However,
When water is supplied through the water supply channel, the water flows directly from the hand toward the distal end while directly touching the outer surface of the endoscope insertion portion. Therefore, when cold water is poured, the endoscope insertion part is immediately cooled, the lens group inside the endoscope insertion part is cooled, and water droplets are attached to the surface of the lens, which causes the observation image by the endoscope. The phenomenon that it becomes cloudy occurs.

原価が嵩む原因ともなる。Further, as disclosed in Japanese Unexamined Patent Publication No. 6-189893, when a pipe line is formed along the endoscope insertion portion, the pipe line forms an elongated closed space. Therefore, the inside of the pipeline is easily clogged with dirt. As a result, dirt or the like cannot be sucked from the distal end of the endoscope insertion portion through the conduit, and it becomes difficult to clean the equipment after use. In addition, by forming a narrow pipeline, the strength of the pipeline is insufficient, and a complicated manufacturing process for forming the pipeline is required,
It also causes the cost to rise.

題も起きる。Further, since the pipe line is formed along the insertion portion of the endoscope, the appearance of the entire insertion portion is not cylindrical,
In some cases, the shape must be uneven. In that case, there are problems such as damage to the patient and the inability to maintain airtightness when combined with a trocar for laparoscopic surgery.

提供することにある。The present invention has been made in view of the above-mentioned problems. The purpose of the present invention is to prevent the endoscope from cooling easily even if cold water is supplied, and to remove dirt from the tip of the endoscope insertion portion. An object of the present invention is to provide a device in which the equipment can be easily washed after use even when sucked, has a higher strength, and has a simple external appearance.
