Abstract
A distractor device includes a longitudinal guiding element and a longitudinal driving element, such as a threaded rod, which may be arranged substantially parallel to the guiding element such that the threaded rod may rotate about a rotation axis substantially parallel to the longitudinal axis of the guiding element. First and second distractor arms are arranged extending along first and second lateral axes from the guiding element. The first and second lateral axes are substantially orthogonal to the longitudinal axis of the guiding element. The first and second distractor arms are captively displaceable along the guiding element, such that the first and second distractor arms are displaceable away from each other by rotating the threaded rod in a first rotational direction, and towards each other by rotating the threaded rod in a second rotational direction, the second rotational direction being opposite to the first rotational direction.
