    摘要： An electrosurgery system includes an electrosurgical generator (10) coupled to or part of an electrosurgical instrument, the generator being operable to generate electrosurgical power in low frequency (typically at 1 MHz) and high frequency bands (typically at 2.45 GHz) either simultaneously or individually. The generator includes a load-responsive control circuit which, in one mode, causes power to be generated predominantly at 1 MHz when the load impedance is high and predominantly at 2.45 MHz when it is low. This allows automatic switching between cutting and coagulation operation. In one embodiment, the instrument includes a gas plasma generator operating such that an ionisable gas is energised in a gas supply passage by the 2.45 GHz component to form a plasma stream which acts as a conductor for delivering the 1 MHz component to a tissue treatment outlet of the passage.

    摘要： A device for morcellating tissue within a body cavity of a patient comprises a stationary tube having a distal end portion, and a bipolar electrosurgical electrode assembly located at the distal end of the tube. The electrosurgical electrode assembly comprises first and second electrodes separated by an insulation member, the bipolar electrosurgical electrode assembly extending around the circumference of the distal edge of the tube. When an electrosurgical cutting voltage is applied to the electrode assembly, and relative movement is initiated between the tube and the tissue, a core of severed tissue is formed within the tube such that it can be removed from the body cavity of the patient. A tissue-pulling device such as a jaw assembly can be employed to pull tissue against the distal end of the tube.

    摘要： An electrosurgical generator for supplying RF power to an electrosurgical instrument for cutting or vaporising tissue has an RF output stage with RF output devices, a series-resonant output network and an RF output. The generator offers improved cutting and vaporising performance, especially in relation to the reliability with which an arc can be struck when presented with an initial load impedance load. This is achieved by virtue of the output stage being capable of maintaining output pulses of at least 1 kW peak by supplying the RF output devices from a large reservoir capacitor. An appropriate combination of cutting performance and haemostasis is provided by allowing for pulsed or continuous wave operation once an arc has been established, according to whether or not a surplus energy condition exists, as indicated by the voltage across the reservoir capacitor.

The apparatus comprises a housing (180) adapted to be placed against the body on which a procedure is to be formed, a first electrode (140) external to the housing for contacting the body, an elongated electrically insulated probe (130) extending from the housing (180) and being insertable into an intracorporeal body cavity (C) in which a procedure is to be performed, a second electrode (150) at the free end of the probe, and circuit means (110) for generating voltage between said first and second electrodes. The method comprises applying a voltage between the electrodes sufficient to cause local ionisation of particles within the body cavity such that they migrate away from the second electrode, thereby removing or reducing the number of particles generated during the procedure from the enclosed atmosphere at or around the site of the procedure.

    摘要： An electrosurgical generator for coagulating tissue comprises a source of radio frequency (RF) energy, and at least a pair of output terminals for connection to a bipolar electrosurgical instrument adapted to contact tissue, the output terminals delivering RF energy from the source to the instrument such that the source delivers RF energy into tissue. The generator also includes boiling detection means for determining when the RF energy starts to cause the boiling of electrolytes within the tissue. A timer is adapted to determine when a predetermined period of time has elapsed since the boiling detection means has indicated the start of the boiling of electrolytes. An indication means gives an indication when the predetermined period of time has elapsed.

    摘要： Apparatus for forming a lesion in body tissue includes a probe having an active region with an electrode for contacting tissue to be treated, and an inactive region including an insulative sleeve around a portion of the electrode. The temperature of the inactive region is monitored using a temperature sensor. A controller supplies radio frequency energy to the electrode and samples signals from the temperature sensor. By performing a calculation using the sampled signals and a predetermined inactive region threshold temperature, and by adjusting the supplied radio frequency power, the inactive region of the probe can be maintained at or below an inactive region maximum temperature while the controller continues to supply radio frequency energy to the electrode. The probe has a second temperature sensor, mounted at a distal end of the electrode, the controller being configured to reduce the supplied radio frequency power when the electrode temperature reaches a predetermined maximum electrode temperature.

    摘要： An electrosurgical system has an electrosurgical generator with a multiple-phase RF output stage coupled to a multiple-electrode electrosurgical instrument. The instrument has three treatment electrodes each of which is coupled to a respective generator output driven from, for instance, a three-phase output transformer. Continuous RF output voltage waveforms are simultaneously delivered to respective generator outputs at the operating frequency, each waveform being phase-displaced with respect to the other waveforms. The magnitude of the RF output voltage waveform delivered to at least one of the generator outputs is sufficient to cause tissue vaporization at the respective treatment electrodes when the system is used for tissue treatment. Also disclosed is an electrosurgical generator in which the output transformer has windings forming at least three phases, the transformer core being constructed to provide at least three magnetic circuits each of which is inductively linked to the windings of at least two of the three phases.
