SYSTEMS AND METHODS FOR TISSUE RETRACTION

摘要

A retractor system for percutaneous surgery in a patient includes first and second retractor portions positionable opposite one another in an incision of the patient. The system also includes at least one actuating member operable to provide an oscillating motion to at least one of the first and second retractor portions. The actuating member is in communication with a controller and is responsive to the controller to oscillate at least one of the first and second retractor portions between a first position and a second position. In another form, a method is directed to retracting tissue for percutaneous access to a surgical site in a patient. However, other embodiments, forms and applications are also envisioned.
