Abstract

A retractor endoscope for less invasive, direct access endoscopic surgery includes a rigid frame capable of supporting applied loads required to perform retraction of an incision site. The rigid frame includes a handle at one end and a lower blade mount rotatably connected to the opposite end. A translation frame is slidably connected to the rigid frame and includes an upper blade mount rotatably connected thereto. Lower and upper blades are removably mounted to the lower and upper blade mounts respectively, with at least one of the blades including pivot mounts for high intensity fiberoptics. The angle of the lower blade along the lower blade mount rotatable connection and the angle of the upper blade along the upper blade mount rotatable connection are independently adjustable. The size of an operating window is determined by the distance between the lower and upper blade mounts and the angles of the lower and upper blades. A method of less invasive, direct access open surgery includes using the retractor with a tool having an angled handle.
