The low frequency module comprises a resonant transformer comprising a ferrite core, a primary coil and a secondary coil, the secondary coil having a larger number of turns than the primary coil, wherein the resonant transformer has a resonant frequency equal to the second frequency. The gas module is adapted to control a flow of an inert gas. | 2021-02-04 |
20210030460 | ELECTROSURGICAL TIP - The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to an electrosurgical surgical tip that includes a conductive and low-profile cutting surface to provide high current density radiofrequency energy with minimal thermal damage to surrounding tissues. For example, an electrosurgical tip of the present disclosure may include a ring of conductive material sputter-coated around a distal opening of a non-conductive base component and a strip of conductive material sputter-coated along a longitudinal axis of the non-conductive base component. | 2021-02-04 |
20210030461 | APPARATUS AND METHOD FOR REGULATING TISSUE WELDER JAWS - A surgical apparatus and methods for severing and welding tissue, in particular blood vessels. The apparatus includes an elongated shaft having a pair of relatively movable jaws at a distal end thereof. A first heating element on one of the jaws is adapted to heat up to a first temperature and form a welded region within the tissue, while a second heating element on one of the jaws is adapted to heat up to a second temperature and sever the tissue within the welded region. The first and second heating elements may be provided on the same or opposite jaws. A control handle provided on the proximal end of the elongated shaft includes controls for opening and closing the jaws, and may include an actuator for sending current through the first and second heating elements. The first and second heating elements may be electrically connected in series, and the first heating element may be bifurcated such that it conducts about one half of the current as the second heating element. A force-limiting mechanism provided either within the control handle, in the elongated shaft, or at the jaws limits the pressure applied to the tissue by the jaws to ensure that the tissue is severed and the ends effectively welded within a short amount of time. | 2021-02-04 |
