This invention relates to a process for incising the transverse carpal ligament in the hand for relief of the symptoms of carpal tunnel syndrome. More specifically, a process is disclosed in which incising energy, preferably laser energy, is introduced from under the ligament for transecting the transverse carpal ligament while permitting the surgeon to view the interface of transection. A probe, preferably attached to a pistol-type grip, includes at least one tube containing an optic viewing device (preferably fiber-optic), and a conduit for directing incising radiation for the ligament transection. The fiber-optic viewing device, energy conduit, and an optional suction tube commence at the pistol grip where they are connected to the requisite viewing device, energy source, and suction pump. The fiber-optic viewing device terminates at a sufficient distance from the pistol grip to permit extension from the insertion at the wrist to pass under the entire length of the transverse carpal ligament. The energy conduit terminates within the field of view of the fiber-optic viewing device for the discharge of ligament-transecting energy in the view of the fiber-optic device and preferably is maneuverable with respect to the probe itself. The protective device keeps vital structures away from the energy tip. The optional suction evacuates smoke and soot from the site of the surgery. An operative process is disclosed which includes the insertion of the probe into the wrist and transection of the transverse carpal ligament during visualization by the surgeon. |
