    • Various embodiments provide an electrosurgical instrument with a disposable electrosurgical cartridge. In one embodiment, the cartridge has first and second energy-delivery surfaces that carry first and second opposing polarity conductors coupled to a voltage source, together with first and second temperature-responsive variable impedance bodies exposed partly in the respective-delivery surfaces. The cartridge further carries a slidable blade member. The temperature-responsive variable impedance bodies are coupled to the voltage source by series and parallel circuitry. In use, the variable impedance bodies are adapted to modulate current flow and ohmic heating in engaged tissue by providing controlled current paths in the tissue and through the variable impedance bodies as the temperature-responsive bodies sense the temperature of adjacent engaged tissue. The engagement surfaces are capable of highly localized modulation of Rf energy application to engaged tissue to provide high and low temperatures, voltage and current in the tissue to create high strength welds.
    • 各种实施例提供具有一次性电外科手术盒的电外科器械。 在一个实施例中,盒具有第一和第二能量传递表面,其承载耦合到电压源的第一和第二相对极性导体以及部分地暴露在相应输送表面中的第一和第二温度响应可变阻抗体。 该盒还带有可滑动的刀片部件。 温度响应可变阻抗体通过串联和并联电路耦合到电压源。 在使用中,可变阻抗体适于通过在温度响应体感测相邻接合组织的温度时通过在组织中和通过可变阻抗体中提供受控的电流路径来调制接合组织中的电流和欧姆加热。 接合表面能够对接合组织进行Rf能量的高度局部调节,以在组织中提供高和低温度,电压和电流以产生高强度焊缝。
