Abstract
A surgical retractor is for use when extended through a trocar sleeve. The retractor has a pair of telescoping tubes. The inner one of the retractor tubes has a number of fingers which may be spread into a fan shape, and then articulated to select a position between 180.degree. and 90.degree. relative to the length of the tubes. For insertion and retraction into and out of the trocar sleeve, the fingers may be pulled into a compact configuration.
