Abstract
A retractor for opening and holding open an incision to allow a surgeon ready access through the incision during an operation or the like. A plurality of substantially opposed flesh engaging blades for engaging the sides of a surgical incision are pivotally mounted on a body which is provided with an aperture for placement over the surgical incision. A trigger is operatively coupled to the plurality of flesh engaging blades to cause the blades to simultaneously diverge from one another to thereby open the surgical incision and to allow the surgeon access into the surgical incision through the aperture in the body.
