Patent attributes
A medical instrument comprising a device for activating or deactivating a function of the instrument. The device comprises first and second parts, which are each movable into an operative position relative to the other part to activate or deactivate a function of the instrument. A second control element for moving the second part into the operative position provides a control portion and comprises, for moving the first part into the operative position, a first control element which provides an additional control portion. The first control element can be moved in an opposite direction the direction from the second control element. Accordingly, the function is activated by moving a control element in a distal direction, and by moving another control element in a proximal direction. A deflection of force by one actuating element for actuating the first part or the second part in the opposite direction is not necessary.
