ABSTRACT:
A cardiovascular retractor is provided which is adapted to be mounted on a thoracic retractor. The cardiovascular retractor includes a clamp support which is mounted along an axis of a thoracic retractor and a retractor blade clamp adjustably secured to a rod of the clamp support. The clamp has a blade grip which grasps a retractor blade. The clamp also includes locking means. When the clamp locking means is not locked, the clamp is adjustable along the clamp support rod, the grip is rotatable in the clamp, the retractor blade is axially adjustable in the clamp, and the retractor blade is rotatable in the clamp. However, when the clamp locking means are locked the clamp locking means securely fix the retractor blade relative to the clamp support so that the retractor blade resists movement and will counteract the tension applied as the cardiovascular retractor is used.
