PROBLEM TO BE SOLVED: To provide a probe which is inserted through an endoscope channel and which enables both imaging by an endoscope body and observation by the probe to be performed with preferable operability and observation properties.SOLUTION: A probe 4 includes at least a light-projecting optical fiber 9 and a light-receiving optical fiber 10 and is configured in such a way that the region of a living organism which is to be observed is irradiated with excitation light guided by the light-projecting optical fiber, and light radiated, due to the excitation light, from the portion to be observed, is received by the light-receiving optical fiber. The probe 4 also includes illumination means used for the capture of an image by the image capturing means of an endoscope body. The illumination means is, for example, a light-emitting diode which is disposed at the front end of the probe, an illumination light guiding optical fiber 11 which guides illumination light from an illumination light source 5c to the front end of the probe, a light-emitting substance piece that is disposed at the front end of the probe and emits white fluorescent by excitation.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】内視鏡チャネルに挿通されるプローブであって、内視鏡本体による撮像及び本プローブによる観察の双方を、操作性、観察性良好に行えるプローブを提供する【解決手段】プローブ4は、少なくとも投光用光ファイバー9と、受光用光ファイバー10とを備えて、投光用光ファイバーにより導光された励起光を生体組織の観察対象部位に照射し、励起光に起因して観察対象部位から放射される放射光を受光用光ファイバーにより受光するように構成され、さらに内視鏡本体の撮像手段により撮像するための照明手段を備えるプローブであり、その照明手段としては、プローブ先端部に配置された発光ダイオードや、照明用光源5cからの照明光をプローブ先端部に導光する照明光導光用光ファイバー11、プローブ先端部に配置され励起により白色蛍光を発する発光物質片などとされる。【選択図】図1
