摘要： A surgical safety apparatus for use in connection with an energizable surgical device prevents inadvertent activation of a surgical tool. The energizable surgical device may include an electrosurgical system, a laser scalpel, an ultrasonic aspirator, and combinations thereof. An activation circuit is in connection with the source of energy and in connection with the handpiece. The activation circuit has two states: the first state disconnects the source of energy from the handpiece, the second state connects the source of energy to the handpiece. A sensing element is connected to the activation circuit. The sensing element signals the activation circuit to convert the activation circuit from the first state to the second state. The activation circuit may remain in the second state for a preestablished period of time followed by a reversion to the first state. The activation circuit may include a relay which may be connected to operate accessories including smoke evacuators, lights, videos or irrigators. The sensing element may be disposed to sense the proximity of the surgical tool to the surgical site. The sensing element may be disposed to sense a voice command. The sensing element can monitor the activations of an electrical switch associated with the surgical tool. If the sensing element detected a specified timed pattern of activations of the electrical switch, for example a double click, then the sensing element would signal the activation circuit to convert to the second state.

摘要： The present disclosure provides a method for determining the probability of a patient burn under a return electrode in a momopolar electrosurgical system comprising calculating a heating factor adjacent the return electrode utilizing a first algorithm, calculating a cooling factor adjacent the return electrode utilizing a second algorithm, subtracting the calculated cooling factor from the calculated heating factor to obtain a difference value, comparing the difference value to a threshold value, and adjusting the power dependent on the relationship of the difference value to the threshold value.

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.
