摘要： A control system and method for the operation of neurosurgical bipolar electrodes for application to the tissue and bodily fluids of a patient provides a source of high frequency energy connected to bipolar electrodes. Contacting surfaces are on the bipolar electrodes of highly electrically conductive material with resistance per unit area substantially less than the impedance of the tissue and bodily fluids. A current transducer attached to the source of high frequency energy responds to the RMS current applied through the tissue and bodily fluids between the contact surfaces as a measure relative to the instantaneous values of the RMS current. A current transducer attached to the source of high frequency energy responds to the RMS current through a capacitor applied across the contact surfaces to provide a signal correlated to the instantaneous values of the RMS voltage between the contacts and across the tissue and bodily fluids. A control connects to the source of high frequency energy for initially regulating the RMS current applied through the tissue and bodily fluids by the contacting surfaces in response to the impedance until the signal divided by the measure reaches a predetermined value. The control regulates the RMS power applied to the tissue and bodily fluids by the contacting surfaces in accord with the impedance until the signal divided by the measure reaches a predefined value. The control responds to the measure and the signal so that the RMS voltage applied to the impedance being treated between the contacting surfaces is regulated while monitored until a prescribed value is reached. The control regulates the RMS voltage applied to the tissue and bodily fluids by the contacting surfaces in accord with the impedance by changing the RMS voltage to a percentage of that applied until the prescribed value is obtained so that the tissue and bodily fluids being treated are moist but coagulated at the surface and not completely dry and carbonized or turned to eschar.

摘要： An apparatus and method are provided for performing parametric measurements using sensor transducer devices to recover frequency variant, amplitude modulated information from encoded sensory signals. A unique network is employed to achieve low-impedance current sensing in conjunction with analog signal decoding. More particularly, the network includes a circuit for current sensing the desired parameter and providing an analog sensor output signal related to the unit measure (i.e., relative value) of the desired parameter. The network also includes a circuit for receiving the demodulating the sensor output signal to obtain a signal representing the electrical equivalence of the measured parameter. The circuit for demodulating employs synchronous sampling techniques and includes a subcircuit, closed-loop through which the demodulated output is fed for generating an offset or error correcting signal. The offset signal is combined with the sensor output signal to generate a resultant signal reflecting static and dynamic changes in the parameter of interest.
