Electrosurgical device including an optical sensor

摘要

An electrosurgical device and system including a blade operatively coupled to an energy source is disclosed herein. The electrosurgical device includes an optical sensor to monitor physical characteristics of the blade such that the device may automatically regulate the energy supplied to the blade and/or the operator may adjust several parameters including how the blade is removed and how much energy is supplied to the blade. A method of using the device and system is also disclosed.

主权项

1. An electrosurgical pencil, comprising:
a housing including a distal portion; an electrode supported within the distal portion of the housing; and an optical sensor assembly configured to measure a temperature of the electrode, the optical sensor assembly including:
a light source configured to provide light;an optical fiber operatively coupled to the light source; andan optical sensor operatively coupled to the optical fiber and configured to detect at least one change in a wavelength of the light transmitted from the light source through the optical sensor, wherein the at least one change in the wavelength of the light corresponds to a change in the temperature of the electrode.
