Abstract

A spreader insert for use with a surgical retractor is provided. The spreader insert includes a circular head with two or more downwardly extending blades. One end of each blade of the insert is rotatably fastened to the head of the insert, such that each blade can be tilted inwardly or extended outwardly from a central axis of the device. Suitable fasteners are provided to rotate the blades from a closed position in which the distal ends of the blades are almost touching each other in order to improve ease of introduction into the surgical field. In an open position, the blades rotate outwardly to hold body tissue in place. Alternatively, the entire spreader insert is machined from a hardenable steel tube, the blades of which are formed so that, when released, they spring outwardly to an open position.
