Handle for a medical instrument

摘要

A handle is provided for a medical instrument having a tubular shaft. The handle comprises at least one movable grip element as well as a coupling portion through which the tubular shaft is connected or can be connected to the handle. The movable grip element is or can be connected to a force transmission element axially movable in the direction of a longitudinal axis of the tubular shaft. Motion of the at least one movable is translated into an axial motion of the force transmission element. The coupling portion is pivotal and lockable relative to a handle axis about a pivot axis running transversely to the longitudinal axis of the tubular shaft. A control element formed as a dual-arm lever is provided whose one lever arm is connected to the movable grip element and whose other lever arm is connected to the force transmission element, such that motion of the movable grip element causes rotation of the control element, which is translated into an axial movement of the force transmission element.
