    摘要: Disclosed herein is a distal end electrode assembly for use in connection with electrosurgical devices, particularly those adapted for the modification, sculpting, resection, removal, or vaporization of tissue, configured for coagulation, cauterization or hemostasis purposes, or utilized for thermal treatment of normal and tumorous tissues. In the context of the present invention, mechanical fastening means, epoxies and other high-temperature adhesives connecting electrode(s) to insulator(s) are replaced with brazed joints to yield electrosurgical devices capable of safely and reliably operating at high power densities and elevated temperatures without thermal failure of the bonds between the electrode and the insulator. The use of brazed joints further permits the construction of miniaturized, compact electrosurgical devices, of both monopolar and bipolar configurations, having utility in a number of divergent fields, from arthroscopy to otolaryngology to oncology, and applicable to both laparoscopic and open surgery techniques. Thus, active electrodes and electrosurgical devices of the present invention maximize efficiency, safety and reliability while minimizing manufacturing cost and device profile.

    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 a 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.

    摘要: A high efficiency electrosurgical ablator which is subjected to a combined oscillatory and mechanical debridement motion during resection of tissue is disclosed. The electrosurgical ablator is positioned in the proximity of the tissue to be treated in the presence of an electrically conductive fluid. A high frequency voltage is applied to the electrode of the ablator, and the electrode is subjected to an oscillatory or other repetitive motion created by an element located within the ablator assembly. The ablator electrode is further connected to a suction assembly that supplies suction from an external source.

    摘要: A high efficiency electrosurgical ablator which is subjected to a fast and slight oscillatory motion during resection of tissue. The electrosurgical ablator is positioned in the proximity of the tissue to be treated in the presence of an electrically conductive fluid. A high frequency voltage is applied to the electrode of the ablator, and the ablator is subjected to a vibratory motion created by, for example, a mechanical or electromechanical oscillator or a piezoelectric element. The vibratory motion permits more tissue to become available in the destructive, sparking zone, thereby increasing the efficiency of operation.

    摘要: Herein disclosed are dual-mode electrosurgical devices designed to function in a first mode in which high-density RF energy is used to cut or vaporize tissue, and then a second mode in which lower-density RF energy desiccates tissue to produce hemostasis, as well as methods of performing electrosurgery using same. Devices formed in accordance with the principles of this invention may be used for any surgical procedure in which highly vascular tissue is cut electrosurgically in a dry or semi-dry field, examples of which include tonsillectomy, liver resection, and cosmetic procedures such as breast augmentation, breast reduction, breast mastopexy, and abdominoplasty.
