The system in order to irradiating the body open part, including the microscopic examination which has the optical waveguide of head conical form, it becomes, the said microscopic examination, it has the hole which passes by with the base, the base and the point which of microscopic examination are wider than the point and the said point, at least partly it connects with the annular body wall, and microscopic examination, in order microscopic examination to be spread light from the illuminant complying with the body wall, it includes the base where the illuminant is accepted. In ideal execution example, the body wall does the fluid channel which sends the fluid to with the point of microscopic examination with the surface and external surface among the body walls and the absorption channel which discharges the fluid from the point of microscopic examination picture forming.身体開口部を照射するためのシステムが、截頭円錐形状の光導波路をもつ検鏡を含んで成り、該検鏡は、先端部、該先端部よりも幅広い基部、検鏡の基部と先端部との間を通る穴をもつ少なくとも部分的に環状の体壁、および検鏡と連結し、検鏡が光源からの光を体壁にそって伝播するように光源を受け入れるベースを含む。好適実施例において、体壁は、体壁の内表面と外表面との間に検鏡の先端部へと流体を送る流体チャネルと、検鏡の先端部から流体を排出する吸引チャネルとを画成する。
