Abstract A self-retaining retractor for use in hand surgery comprising a paddle-shaped pallet with notches around its periphery on which the hand is placed wound-side up, elastic bands for holding the fingers in place on the pallet and at least one flexible balland-link chain with a hook at one end which is hooked over the edge of the wound and which is fastened to the pallet edge at a predetermined point along its length by inserting one of its links into one of the pallet notches, thereby holding the wound open.
