Abstract
The present invention is a new kind of bipolar coagulating instrument which has special application in certain microsurgical or neurosurgical contexts in which one must grip and coagulate a web of tissue or membrane which is inside a deep surgical hole, and where the web hangs from the side wall of the hole and is in a plane perpendicular to the line of sight. The instrument must then be adapted to grip the hanging membrane with its tips and close down on the membrane in a direction which is parallel to the line of sight, and then apply a coagulating potential to its tips to coagulate the membrane. The invention then has a side-biting tips which close in a longitudinal direction, i.e. parallel to the line of sight or the distal axis of the instrument, and which has tips that are electrically insulated to become the two poles of the coagulating electric potential. Thus this longitudinally, side-biting, bipolar coagulating, surgical instrument is in marked contrast to conventional bipolar coagulating forceps, the tips of which always close in direction which is transverse, i.e. perpendicular, to the direction of line of sight or the distal axis of the instrument.
