PROBLEM TO BE SOLVED: To achieve compatibility between the ease of piercing a probe for living tissue into a living tissue for detecting its reactions and the follow-up ability of the probe to the tissue after it is retained in the living tissue.SOLUTION: The probe for living tissue has a cylindrical tube constituted of a shape-memory alloy that becomes an austenite phase at a temperature higher than the body temperature of a living tissue and becomes a martensitic phase at the body temperature of the living tissue, and a fluid mechanism for recovering the tissue fluid from a living tissue and/or injecting a liquid medicine into the living tissue. The tube contains at least the fluid mechanism in part.COPYRIGHT: (C)2010,JPO&INPIT【課題】生体組織の反応を検出する生体組織プローブにおいて、生体組織への刺入の容易さと、生体組織留置後の生体組織への追従性とを両立する。【解決手段】生体組織の体温よりも高い温度でオーステナイト相となり、生体組織の体温でマルテンサイト相となる形状記憶合金によって構成された筒状のチューブ部と、生体組織からの組織液の回収及び/又は生体組織への薬液の注入を行う流体機構部とを有し、チューブ部の内部に流体機構部の少なくとも一部が収納される。【選択図】図2
