Abstract:
1. A surgical retractor comprising: a first arm having a utility end and a handle end comprising a first finger hole; a first blade having proximal and distal ends wherein the proximal end is connected to the utility end of the first arm, the first blade being pivotally and lockably adjustable about the longitudinal axis of the utility end of the first arm; a second arm having a finger lever, a ratchet lock, a utility end and a handle end comprising a second finger hole; a second blade having proximal and distal ends wherein the proximal end is connected to the utility end of the second arm, the second blade being pivotally and lockably adjustable about the longitudinal axis of the utility end of the second arm; a first spring connected to the first blade and the first arm; the first spring exerting pressure on the first arm and on the first blade to bias the distal end of the first blade toward the distal end of the second blade; a second spring connected to the second blade and the second arm; the second spring exerting pressure on the second arm and on the second blade to bias the distal end of the second blade toward the distal end of the first blade; wherein the first and second arms are adjustably connected between a closed position having a small distance between the utility end of the first arm and the utility end of the second arm and at least one open position having a larger distance between the utility end of the first arm and the utility end of the second arm and wherein the closed position is further characterized by the utility ends of the first and second arms being substantially parallel; and wherein said first and second blades are pivotally and lockably adjustable so as to be capable of providing a larger opening between said blades inside a surgical cavity than at an entrance to said surgical cavity.
