An improved visceral retractor is provided for use by a surgeon during closure of a surgical incision or the like. The visceral retractor comprises an elongated, relatively thin sheet of flexible plastic or rubber-based material having a generally fishlike shape to include a generally oval body portion joined by a relatively narrow waist region to a comparatively small tail portion. Either the body portion or the tail portion is insertable through an incision, depending upon the size of the incision, to separate underlying internal organs from overlying tissue thereby preventing the organs from bulging into the incision or from being sutured as the incision is closed. With a relatively large incision, the body portion may be inserted during initial suturing until the incision is closed to a smaller size, whereupon the retractor is reversed and the tail portion is inserted during further suturing. In one form of the invention, the visceral retractor is imprinted with contoured pattern lines indicating smaller sizes to which the retractor may be cut for use with smaller incisions.
