PROBLEM TO BE SOLVED: To provide a medical probe which can measure a dynamic component of a blood flow or the like inside a biological tissue without hiding a surface of the biological tissue.SOLUTION: A medical probe 2 includes: a first transmission channel 8 which transmits laser beams P, Q emitted to a biological tissue A and emits from an emission end 8a; a second transmission channel 9 which receives scattering light from the biological tissue A including information on a dynamic component in the biological tissue A at an incident end 9a and transmits the light; an optical element 10 which refracts the laser beams P, Q emitted from the emission end 8a to emit the refracted laser beams to the biological tissue A, condenses the scattering light R from the biological tissue A to allow the incident end 9a to receive condensed light, and has positive power as a whole; and a separation element 11 which separates the scattering light R returning from the biological tissue A along an optical path of the laser beams P, Q refracted by the optical element 10 from the optical path of the laser beams P, Q to make the separated scattering light be incident on the incident end 9a.SELECTED DRAWING: Figure 2【課題】生体組織の表面を隠すことなく生体組織内の血流等の動的成分を測定することができる医療用プローブを提供する。【解決手段】生体組織Aに対して照射するレーザ光P,Qを伝送し射出端8aから射出する第1の伝送路8と、生体組織Aにおける動的成分の情報を含む生体組織Aからの散乱光を入射端9aにおいて受光して伝送する第2の伝送路9と、射出端8aから射出されたレーザ光P,Qを屈折して生体組織Aに照射するとともに、生体組織Aからの散乱光Rを集光して入射端9aに受光させる、全体として正のパワーを有する光学素子10と、光学素子10により屈折されたレーザ光P,Qの光路に沿って生体組織Aから戻る散乱光Rをレーザ光P,Qの光路から分離して入射端9aに入射させる分離素子11とを備える医療用プローブ2。【選択図】図2
