摘要
Electrosurgical forceps are described that have jaws capable of being closed relative to one another, the jaws each supporting electrode structures especially shaped to enhance the ability of the instrument to desiccate/seal or cut tissue structures clamped between the opposed jaws. One of the opposed jaws has a generally arcuate cross-section with a raised central zone and the other electrode has a recess adapted to accommodate the raised central zone of the cooperating electrode. By appropriating the shaping the mating electrode surfaces, tissue structures placed between the jaws are stretched laterally as clamping occurs. The stretching action prevents bunching of the tissue and results in improved desiccation, sealing and cutting. A fine, uninsulated conductor disposed on the one jaw, but insulated from the electrode surface on that jaw, serves as a cutting electrode.
