【 要旨 】 最近,オリンパス社は,術者が容易な操作で任意に硬度を変更できる硬度可変式大腸内視鏡(3機種)を製品化した.それらは,極細径のコイル&ワイヤ方式による硬度可変機構を採用しているため,従来の大腸内視鏡と比べ,サイズ,光学系,彎曲性能などの仕様は劣らない.そして,それら3機種の硬度可変式大腸内視鏡は,さまざまな術者の手技に対応できるように,各々外径や硬度(最軟~最硬)が異なるものとなっている.また,硬度可変式大腸内視鏡の取り扱いにおいては,検査前の点検や,検査後の消毒,保管において留意すべき点がいくつかある.

Title Variable Stiffness Colonoscope -- Structure and Handling
Author Hiroki Moriyama Gastrointestinal Products Business Department, Olympus Optical Co., Ltd
[ Summary ] There has been the needs for a user to change the stiffness of a colonoscope at their discretion, during insertion. Auxiliary instruments, such as the splinting tube were developed to meet this need. However, since they are separated from the scope, it is cumbersome to handle them. Olympus has recently introduced three kinds of colonoscopes equipped with a variable stiffness function, which allows the user to easily change the stiffness of the endoscope, at will. To produce this variable stiffness function, an ultra-thin coil and wire system was adopted. These variable stiffness colonoscopes, therefore, have specifications comparable to those of conventional types, in terms of size, an optical system, angulation performance, etc. These three kinds of colonoscopes are available in different sizes and levels of stiffness so that they can accommodate differences in technique by various users. Regarding the handling of these variable stiffness colonoscopes, there are some points to consider in relation to preendoscopic inspection, and disinfection/storage after examination.
Olympus will continue to develop endoscopes, aiming at easier and safer examinations.
