PROBLEM TO BE SOLVED: To provide a biological tissue grasping mechanism capable of grasping a biological tissue stably and also realizing stable opening and closing operation of a grasping member.SOLUTION: A biological tissue grasping mechanism 16 comprises: a body member 30； a parallel linkage mechanism 32 that is connected to the body member 30； a grasping member 34 that is connected to the body member 30 through the parallel linkage mechanism 32 and can perform opening and closing operation； and a drive wire 26 that is arranged so as to realize relative displacement to the body member 30 in an axial direction. The grasping member 34 performs the opening and closing operation by the displacement of the drive wire 26.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】安定的に生体組織を把持することができるとともに、把持部材の安定した開閉動作を実現できる生体組織把持機構を提供する。【解決手段】生体組織把持機構１６は、ボディ部材３０と、ボディ部材３０に連結された平行リンク機構３２と、平行リンク機構３２を介してボディ部材３０に連結されるとともに開閉動作可能な把持部材３４と、ボディ部材３０に対して軸方向に相対変位可能に配置された駆動ワイヤ２６とを備える。駆動ワイヤ２６の変位により、把持部材３４が開閉動作する。【選択図】図２
