CAVITATING ULTRASONIC SURGICAL ASPIRATOR WITH RF ELECTRODES |
摘要 |
An CUSA having a cannula with an ultrasonic frequency vibrating tip with a flue disposed around the cannula. A first electrode is disposed on an outside of the flue and an RF generator provides current to the first electrode. A current flow is formed between the electrode and the tip and the tip acts as a ground. The first electrode can take the shape of a complete circumferential ring or a partially circumferential ring. The first electrode can be removably disposed on and/or movable along a length of the flue to allow the surgeon to "clip-on" or adjust the electrode at the position of their choice. A second electrode can be disposed on the outside of the flue and proximal to the first. A second current flow can be formed between the first electrode and the second electrode. |
