ABSTRACT:
A device and method for treating a patient who is experiencing carpal tunnel syndrome is provided. The invention involves a cannula which has a closed blunt end and an open end. The cannula is dimensioned so that an endoscope and a knife can be simultaneously manipulated inside the cannula. A slot is provided between the ends of the cannula for viewing and incising the carpal ligament. The cannula preferably has a handle attached near its open end. The cannula is typically employed in conjunction with an endoscope and a knife to cut the patients transverse carpal ligament through a small wrist incision, thereby minimizing trauma to surrounding tissue, and post-operative recovery time.
