Bipolar surgical instruments having focused electrical fields
TLDR
A bipolar surgical device comprises a pair of actuable jaws as mentioned in this paper, which are laterally spaced-apart and arranged in a linear manner so that the lateral distance there between remains generally constant.Abstract:
A bipolar surgical device comprises a pair of actuable jaws. A first electrode member which optionally includes a line of electrically coupled tissue-penetrating elements is formed on one of the jaws, and a second electrode member which optionally includes a line of electrically coupled tissue-penetrating elements is formed on the same or the other jaw. The electrode members are laterally spaced-apart and arranged in a parallel, usually linear manner so that the lateral distance therebetween remains generally constant. In operation, tissue may be grasped between the jaws so that the electrode members contact and/or the tissue-penetrating elements enter into the tissue. By energizing the electrode members at opposite polarities using a high frequency energy source, tissue between the jaws will be heated, coagulated, and/or necrosed, while heating of tissue outside of the lines will be minimized.read more
