Abstract

The invention relates to a surgical retractor, in particular, for spreading a severed sternum, comprising a first retaining device and a second retaining device, which each have a spreader arm with at least one retaining element held thereon, a holding device for holding the retaining devices on each other, and a drive device with which the distance of the spreader arms from each other along a retraction direction is alterable for transfer to a spread position. In order to provide a retractor of this kind which, having a compact design, is easy to handle, it is proposed in accordance with the invention that the retaining devices each have a holding arm connected to the respective spreader arm, and both holding arms couple with the drive device and be displaceable via the drive device relative to each other and relative to the holding device along a displacement direction.
