<p>A probe (100) for use in electrosurgery includes a lumen (101 ) having a proximal end (101 a) and a distal opening (101 b). There is an electrode (103) within the lumen which has a proximal end (103a) connectable to a high frequency current source (105) and a discharge end (103b) recessed within the lumen. The lumen includes a gas outlet (107) in a distal region of the lumen for releasing gas pressure. During use, when the distal opening (101 b) of the lumen (101 ) contacts target tissue while the electrode is activated, gas pressure within the lumen is released through the gas outlet (107) thus avoiding gas embolism. A probe attachment (300) is also provided.</p> |
