Abstract
A retractor for use in surgical operations comprises a pair of blade assemblies. In operation, the blade assemblies are initially in a closed position to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The retractor is adapted to rotate a first blade about a first axis and a second blade about a second axis. The retractor is adapted to move the pair of blade assemblies apart along a third axis. The retractor is adapted to pivot the first blade about a fourth axis and the second blade about a fifth axis. In some embodiments, a method of performing an operation, e.g. a spinal operation, on a patient using the disclosed retractor is provided.
