Abstract
Bipolar surgical instruments for simultaneously cutting and coagulating tissue are provided that feature increased manufacturability and durability, reduced component cost and reduced assembly requirements. The bipolar instruments include opposite polarity electrodes isolated by a layer of electrical insulation deposited and specially prepared to reduce electrical breakdown and increase smoothness. A pivot pin connecting the electrodes is impregnated with hydrophobic material, and organic materials are generally avoided in the components and manufacture of the instruments. A simplified design for an endoscopic bipolar instrument is also provided to reduce cost and improve manufacturability and durability of such devices.
