Abstract
A medical operation apparatus includes a body graspable by an operator, an operation part that is arranged to enable a part of the operation part to be moved relative to the body, and a holder that receives the fingers of the operator and transmits a movement of the fingers to the operation part. The holder includes a contact portion that comes in contact with the body, and a connector that supports a relative posture of the holder and the operation part so as to change the relative posture in accordance with a posture change of the fingers of the operator. In a relative arrangement position of the operation part and the body, when the relative posture of the holder and the operation part is changed, an amount of change in the relative arrangement position of the body and the operation part is within a specified permissible range.
