Multifunctional electrosurgical apparatus

摘要

An electrosurgical apparatus having improved placement accuracy is provided. The electrosurgical apparatus comprises an elongate shaft having a proximal region, a distal region and at least one lumen therethrough, a conductive region at the distal region for delivery of energy to the tissue, at least one aperture defined by the shaft, an electrical coupling means at or near the proximal region for flexibly coupling a power source control unit to supply energy to the conductive region and a fluid delivery connection interface flexibly coupled at or near the proximal region for coupling a fluid delivery mechanism. The apparatus further comprises a temperature sensing means and may also comprise a means of occluding a distal end of the apparatus. The apparatus may beneficially be used to treat pain.
