ABSTRACT:
A retractor for use in partial sternotomy includes a toothed crossbar to which a pair of small, parallel grips are attached. The first grip is attached to an arm which is fixed to one end of the crossbar. The second grip is attached to an arm which is movably attached to the crossbar by a pinion, thereby permitting the second grip to be moved along the crossbar toward or away from the first grip. A first rod is connected to the fixed arm by means of a bracket, while a second rod is connected to the movable arm by means of a similar bracket. Retractor blades of different configurations can be connected to the rods by universal clamps. Suture holders are disposed atop each of the arms. A holder for a carbon dioxide tube can be removably connected to the toothed portion of the crossbar.
