ABSTRACT:
Arched arms fit over the contour of the chest cavity. Retractor blades are attached to the arms at one end by pivot pins allowing complete rotation vertically of the arms relative to the blades. The blades are attached to the pivot pin by joints which are slightly rotatable in a horizontal direction. Opposite the blade end, a rack bar is rigidly secured to one arm and slides through a slot in a housing at the end of the other arm, A pinion and handle in the housing moves the rack to separate the blades at the other end and bring them together again.
