The system and method provides a retractor and use which gives the traditional ability to apply force and hold the surgical field open, but with the ability to select the depth, and shape of retraction tips for use during surgery, and in particular, spinal surgery. Any surgery may be carried out in an open surgical field with minimal patient trauma. A keyhole surgical opening accords a surgeon a maximum open operating field and necessitates only a minimal incision. An instrumentation-interchangeable tip junction facilitates the inserted support of interchangeable tips and may preferably include a connection shape which provides for a rotation lock.
