  • Variable-frequency stimulator for electrosurgery
    Patent number: 10092349
    Abstract: A variable-frequency stimulator for electrosurgery includes an impedance analyzer to identify the electrical impedance of biological tissue being treated by an electrosurgical instrument, such as a laparoscope. Based on the identified tissue impedance, a controller adjusts the frequency of electrical current delivered to the electrosurgical instrument to reduce, minimize or normalize the impedance of the tissue, thereby preventing collateral damage to the tissue in and about the surgical site. Additionally, the laparoscope may be configured with multiple electrically conductive grasping arms that are used to deliver the electrical current to the surgical site. The conductive grasping arms provide multiple current paths for the electrical current to flow, thus concentrating the electrical current at the surgical site during an electrosurgical procedure.
