るようにしていた。 In general, endoscopes use the operating section to bend the insertion tube and perform operations such as supplying air and water, but in recent years, even more functions have been added to the operating section. I'm getting used to it. That is, the operation section has additional functions such as suction operation, forceps raising operation, air supply operation of other fluids (for example, CO 2 gas), and focus adjustment operation, and also has functions such as multiple forceps channels, liquid medicine, etc. They have come to be equipped with injection ports for injecting water. When such a wide variety of functions are added,
In the past, the main body of the operating section was made thicker or longer to accommodate the above-mentioned functions in a single main body.
しかしながら、操作部の本体を太くした場合に
は術者の手指の自由度が少なくなり、主機能の操
作がしづらくなり、また、操作部を長くすると操
作部の取り回しが行ない難く操作性が低下する不
都合があつた。 However, when the main body of the operating section is made thicker, the surgeon's fingers have less freedom, making it difficult to operate the main functions, and when the operating section is made longer, it becomes difficult to maneuver around the operating section, reducing operability. There was an inconvenience.
本発明は上記事情に着目してなされたもので、
その目的とするところは、操作部に多数の操作機
