Abstract: A retractor instrument for opening a surgical incision on a human limb having a first tissue holder for grasping an edge of the incision, a second tissue holder for grasping another edge of the incision, a band extending from the first tissue holder to the second tissue holder in a generally circular configuration around the limb away from the incision, and an adjustor connected to the band so as to vary a distance between the first and second tissue holders. The band includes a first band member connected to the first tissue holder and a second band member connected to the second tissue holder. The adjustor is a clamp which is suitable for engaging grooves formed in the first band member. The tissue holders are rake members having a plurality of prongs extending therefrom. The rake members are pivotally connected to the ends of the bands. The first band member and the second band member are arranged in overlapping configuration.
