Abstract:
A surgical retractor wherein a plurality of segments are strung together on a strand which may be tensioned; the segments are separated from each other by spacers also strung on the strand; the mating surfaces of the segments are concave and the intervening spacers are convex; tensioning of the strand causes the segments and spacers to frictionally engage each other and rigidize the attitude of the segments with respect to each other.
