Abstract
In an episiotomy retractor, distal portions of the blades are shaped to diverge away from one another for enhanced retraction and gripping of respective adjacent vaginal walls, proximal portions of the blades are shaped to diverge away from one another to retract the labia as the blades retract respective adjacent vaginal walls, and the proximal inferior longitudinal edges of the blades cooperatively define, when the retractor is in use, an open work area for a surgeon about the perineum and the posterior vaginal wall of a patient.
