Abstract
A laparoscopic cauterization electrode for connection to a source of appropriate electrical power for performing deep surgical operations through an opening in a body such as deep thorax, abdominal perineal, deep rectum, deep gynecological and similar deep body operations, comprising an electrically conductive electrode shaft of a width sized for insertion through the body opening having a proximal and a distal end, the proximal the of said electrode adapted for electrical connectivity to the power source and the distal end having teflon-coated operative tip associated therewith, insulation for providing both electrical and thermal insulation and abrasion resistance along the electrode shaft between the proximal and distal ends of the electrode and the electrode shaft being of a sufficient length to extend from the exterior into the interior of a body for performing the deep surgical operations.
