DEVICES AND METHODS FOR ABLATING AND REMOVING A TISSUE MASS

摘要

Disclosed herein are high efficiency surgical devices and methods of using same using radio frequency (RF) electrical power to destroy, vaporize and remove soft tissues, such as tumors, both malignant and benign, from within a target surgical site. In one particularly preferred embodiment, the electrosurgical device employs a combination of rotary and translational motion to incrementally vaporize a calculated volume of tissue. According to the principles of this invention, the electrosurgical devices can be used with externally supplied conductive or non-conductive irrigants, whether liquid, gas, or gasa combination thereof, as well as without externally supplied liquids, a mode of operation often referred to as dry field environment. The electrosurgical devices may further optionally include aspiration components to permit removal of vaporization by-products.
