Abstract
Various embodiments disclosed relate to a device and methods for electrosurgery, where the device end effector includes an anti-smoke layer. The present disclosure includes a device having first and second electrodes that include the anti-smoke layer, which can be a hydrophobic layer to aid in reduction of smoke production during operation.
Claims15
A device for smoke reduction in electrosurgery, the device comprising:
- a DC smoke ionization electrode, configured to be coupled to a DC voltage source to provide an ionizing DC voltage to a surgical site to ionize smoke particles and to reduce a level of smoke present at the surgical site;
- and
- a radiofrequency (RF) electrical current conductive low adhesion layer comprising one or more hydrophobic pillars, on a substrate, at least partially covering the DC smoke ionization electrode;
- and
- wherein the DC smoke ionization electrode is further configured to be coupled to an RF energy source to receive RF energy and to also pass the RF electrical current through the RF electrical current conductive low adhesion layer to affect target tissue at the surgical site.

A method of reducing smoke at a surgical site, the method comprising:
- applying a DC voltage to a DC smoke ionization electrode at the surgical site;
- and
- providing an ionizing DC voltage to the surgical site to ionize smoke particles and to reduce smoke at the surgical site,
- wherein the DC smoke ionization electrode is at least partially covered by a radiofrequency (RF) electrical current conductive low adhesion layer comprising one or more hydrophobic pillars on a substrate, the RF electrical current conductive low adhesion layer having a surface energy less than that of an underlying portion of the smoke ionization electrode, and
- wherein the DC smoke ionization electrode is further configured to be coupled to an RF voltage source to receive RF energy and to also pass the RF electrical current through the RF electrical current conductive low adhesion layer to affect target tissue at the surgical site.
