<p>The invention concerns a lock device for use in connection with elongated surgical instruments such as surgical needles, electrodes, etc., wherein the lock device consists of at least a first and a second distance member which surround the surgical instrument and a third stop member. All the parts are movable in the longitudinal direction relative to the instrument and thereby relative to one another, they are individually lockable in the depth position relative to the instrument and are equipped with indication devices for indication of position relative to one another, with the result that the instrument's movement in the longitudinal direction (depth) is controlled by controlling the distance for the relative movement between the distance members.</p> |
