Abstract
An apparatus for endoscopic surgical treatment of carpal tunnel syndrome, heel spur syndrome, or other conditions requiring fibrous tissue division and a method for endoscopic treatment of carpal tunnel syndrome are disclosed which include a slotted cannula, an obturator for guiding the cannula into a body opening, an elevator, a retractor, and a hooked surgical knife. The elevator and retractor are used in separating tissue at a surgical opening into the wrist, hand, foot or other location and the obturator and cannula are inserted into the opening for endoscopic division of the carpal ligament, plantar fascia or other tissue. The obturator is removed and a videoarthroscope is inserted in the one end of the cannula while the knife is inserted in the other end to permit direct observation of the procedure as the ligament is divided in one step. The instruments are very small and leave only small openings which reduce the trauma and facilitate early recovery from the surgical procedure.
