PROBLEM TO BE SOLVED: To provide a method for quickly and easily cleaning a nasal hard mirror lens part having poor visibility due to adhesion of blood or the like in a nasal surgery, and to provide a nasal hard mirror lens part cleaning tool not narrowing a work space of the nasal surgery.SOLUTION: The nasal hard mirror lens part cleaning tool includes: a main tubular member including a lumen communicating a distal end and a proximal end and a sub tubular member including a lumen supplying cleaning water. The main tubular member includes a hole penetrating from an outer side face to an inner side face of a tube wall, an inner diameter of the main tubular member from the proximal end to distal end corresponds to an outer diameter of a hard mirror, and a groove is formed on a tube wall inner face from the mouth of the hole opened in a tube wall inner side face to the distal end of the main tubular member. The sub tubular member is connected such that the lumen is communicated with the lumen of the hole opened in the tube wall side face of the main tubular member, and supplied cleaning water flows along an outer side face of the hard mirror by utilizing surface tension of the cleaning water.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】経鼻手術において血液などの付着で視界不良となった経鼻硬性鏡のレンズ部を迅速かつ容易に洗浄する方法および経鼻手術の作業スペースを狭めない経鼻硬性鏡レンズ部用洗浄具を提供する。【解決手段】 遠位端と近位端を連通する内腔を有する主管状部材と、 洗浄水を供給するための内腔を有する副管状部材とを具備し、 前記主管状部材は、その管壁の外側面から内側面までを貫通する孔を有し、 主管状部材の近位端から遠位端までの内径が硬性鏡の外径に対応する大きさであり、且つ管壁内側面に開いた前記孔の口から主管状部材の遠位端までの管壁内面に溝があり、 副管状部材は、その内腔が主管状部材の管壁外側面に開いた前記孔の内腔に連通するように接続されていて、供給された洗浄水が硬性鏡の外側面を洗浄水の表面張力を利用して伝わり流れるようにすることができる、経鼻硬性鏡レンズ部用洗浄具。【選択図】図1
