摘要： Endoscopic surgical instruments (10) are provided that have bipolar electrodes on opposing movable members (18, 19) for passing a high frequency current through tissue for simulataneously severing or manipulating the tissue and causing hemostasis of the tissue. An electrically insulating material is interposed between the movable members so that the electrodes are spaced apart from .002 to 0.050 inches and the current passes between the opposing electrodes through the tissue.

摘要： A surgical instrument is described that incorporates bipolar electrodes on opposing shearing members (21,31) for passing a high frequency current through the tissue for causing hemostasis of the tissue and for cutting the tissue. An electrically insulating material (13) is interposed between the shearing members so that the electrodes are spaced apart from .002 to 0.050 inches and the current passes between the opposing electrodes through the tissue and not between the opposing shearing surfaces (22,32). The insulating material (13) has a higher hardness than the opposing members to reduce wear of the insulation and provide a self-sharpening feature.
The use of a constant voltage high frequency power supply to deliver current to the tissue to cause hemostasis is described.

摘要： A hemostatic surgical blade (10) and methods of manufacturing such blades are provided, wherein the blade comprises a laminate region (40) having a hardenable center layer (22) and highly thermally conductive outer layers, joined to a second region of a low thermal conductivity material (21). A heating element (16) is secured to the laminate region and in thermal communication therewith to thermally reform the collagen of tissue as it is incised. The heat generated by the heating element (16) is conducted to the cutting edge (13) of the blade to maintain the cutting edge temperature within 20 °C to 70 °C of a user-selected operating temperature. The second region (21) reduces the conduction of heat to the handle of the instrument. The heating element (16) comprises a thermally conductive dielectric layer attached to an outer surface of the laminate region (17), resistive conductive elements deposited on the dielectric (18), a second dielectric layer (19) covering the resistive conductor elements, and an adherent coating (12) disposed thereon to reduce coagulum buildup on the blade.
