    • An electrosurgical generator for applying output power to tissue (14) to desiccate tissue. The electrosurgical generator comprises a controller (12) for cycling the output power to cause a cycling of the tissue impedance; and a tissue impedance measurement circuit (15) coupled to said controller for measuring impedance of the tissue. The controller cycles the output power by applying a predetermined amount of output power to said tissue, lowering the output power upon an output voltage reaching a predetermined maximum, re-applying the predetermined amount of output power to said tissue if a measured tissue impedance does not indicate desiccation of the tissue, and terminating output power when the measured tissue impedance exceeds a predetermined value, the predetermined value corresponding to a desiccated condition of the tissue.

    • An electrosurgical generator has an output power control system (10) that causes the impedance of tissue (14) to rise and fall in a cyclic pattern until the tissue (14) is desiccated. The advantage of the power control system (10) is that thermal spread and charring are reduced. In addition, the power control system (10) offers improved performance for electrosurgical vessel sealing and tissue welding. The output power is applied cyclically by a control system with tissue impedance feedback. The impedance of the tissue follows the cyclic pattern of the output power several times, depending on the state of the tissue (14), until the tissue becomes fully desiccated. High power is applied to cause the tissue (14) to reach a high impedance, and then the power is reduced to allow the impedance to fall. Thermal energy is allowed to dissipate during the low power cycle. The control system is adaptive to tissue in the sense that output power is modulated in response to the impedance of the tissue.
    • 电外科发生器具有输出功率控制系统(10),其使得组织(14)的阻抗以循环模式上升和下降直到组织(14)干燥。 功率控制系统(10)的优点是减少了散热和炭化。 此外,功率控制系统(10)提供了电外科容器密封和组织焊接的改善的性能。 输出功率由具有组织阻抗反馈的控制系统周期性地施加。 取决于组织(14)的状态,组织的阻抗几次遵循输出功率的循环模式,直到组织完全干燥。 施加高功率以使组织(14)达到高阻抗,然后降低功率以允许阻抗下降。 允许热能在低功率循环期间消散。 在输出功率响应于组织的阻抗被调制的意义上,控制系统适应于组织。

    • Bei einer Regelanordnung für die Leistungsendstufe (E) eines frequenzvariablen Senders, welche die Amplituden der auf der Antennenzuleitung vorlaufenden und rücklaufenden Wel­len mißt und zur Ableitung eines Regelsignals auswertet, werden aus dem Sendesignal vor der Endstufe zwei gleich­frequente um 90° gegeneinander phasenverschobene Überla­gungssignale abgeleitet (SI, SQ). Die mittels eines Richtkopplers (RK) aus der Antennenzuleitung (L) ausgekoppelten, den vorlaufenden und rücklaufenden Wellen proportionalen Signalspannungen werden in Quadraturamplitudendemodulatoranordnungen (DQR, DQV) mit den beiden Überlagerungssignalen umgesetzt und aus den niederfrequenten Anteilen werden Vorlauf- und Rücklaufsi­gnale zur Ableitung eines Regelsignals für den Verstär­kungsfaktor der Leistungsendstufe gewonnen. Fremdsignale auf der Antennenzuleitung führen nicht zu einer Reaktion des Regelkreises.
