Abstract
The invention relates to a medical instrument having on its proximal end a shaft with a handle consisting of two gripping members and on its distal end a tool consisting of two jaw members and in which, to open and close the tool, at least one jaw member can rotate with respect to the other jaw member around a point of rotation by means of a push-pull rod and in which the push-pull rod is connected on the proximal side with a rotatable gripping member of the handle. To produce a medical instrument that can be used even in closely confined spaces and with sufficient transmission of force, it is proposed with the invention that the point of rotation should be configured as a variable, virtual point of rotation that is dependent on the position of the jaw members to one another.
