Electrosurgical device having a multiplexer
First Claim
1. An electrosurgical system, comprising:
- an electrosurgical generator configured to provide electrosurgical energy to an electrosurgical device coupled thereto which, in turn, is configured to deliver electrosurgical energy to tissue, the electrosurgical device including;
a plurality of sensors configured to detect at least one tissue property and output a detected tissue property signal relating thereto;
at least one multiplexer having a plurality of channels, each channel of the plurality of channels electrically connected to a respective sensor of the plurality of sensors, the at least one multiplexer configured to receive the detected tissue property signal from each sensor of the plurality of sensors and output at least one output signal along at least one signal line, wherein the at least one signal line is configured to connect to the electrosurgical generator to control a power output of the electrosurgical generator;
user-operated controls associated with the electrosurgical generator configured to select at least one variable from the group consisting of temperature, impedance, electromagnetic field, fluid pressure, tissue density, and piezoelectric voltage; and
a channel select system configured to select at least one channel from the plurality of channels as a function of the at least one user-selected variable.

Abstract
An electrosurgical system includes an electrosurgical generator configured to provide electrosurgical energy to an electrosurgical device coupled thereto which, in turn, delivers electrosurgical energy to tissue. The electrosurgical device may include a plurality of sensors configured to detect one or more tissue properties and output a detected tissue property signal relating thereto. One or more multiplexers having a plurality of channels are electrically connected to each of the corresponding plurality of sensors. The multiplexer(s) may be configured to receive the detected tissue property signal from each sensor of the plurality of sensors and output at least one output signal along a signal line. The signal line is configured to connect to the electrosurgical generator to control a power output of the electrosurgical generator. A channel select algorithm is configured to automatically select channels from the plurality of channels.
