A medical instrument according to the present disclosure includes a contact portion that contacts a biological tissue, a drive portion that generates a driving force for bringing the contact portion into contact with the biological tissue, and a contact force of the contact portion on the biological tissue. And a limiter mechanism that restricts transmission of the driving force to the contact portion. With this configuration, it is possible to limit the force applied to the living tissue during the operation with a simple configuration and to reduce the risk of failure.本開示に係る医療用器具は、生体組織に接触する接触部と、前記生体組織に前記接触部を接触させるための駆動力を発生させる駆動部と、前記生体組織への前記接触部の接触力に応じて、前記駆動力の前記接触部への伝達に制限をかけるリミッター機構とを備える。この構成により、簡素な構成で術中に生体組織に与える力を制限するとともに、故障リスクを低減することができる。
