A method is provided for making an electrode tip for use in a bipolar electrosurgical instrument from a single flat blank of metal. The method uses a photo chemical machining process. The resultant electrode tip has a generally loop shaped working portion. Use of the flat blank of metal results in electrodes having working portions with sharp edges in cross-section. The working portions emit concentrated energy in the radial direction.

Method of making flat loop bipolar electrode tips for electrosurgical

An electrode tip is provided for use in a bi polar electrosurgical instrument. The electrode tip has a generally loop shaped working portion, including a first and second electrode, The first electrode is generally loop shaped. The second electrode generally surrounds the first electrode and is generally spaced from and coplanar with the first electrode. The electrodes have sharp edges in cross-section which emit concentrated energy in the radial direction.

Briefly stated, the present invention comprises a resuscitation mask for administering artificial respiration to a patient. The respiration mask has a container for defining an interior region between the container and the face of the patient. Two conduits are provided through the container wall in order to define two air flow passageways which are in fluid communication with the internal region. A valve is disposed in one air flow passageway for permitting air flow into the internal region and preventing air flow from the internal region. A vent is provided to reduce pressure within the internal region in response to an increase in pressure within the internal region. The container is generally cup-shaped and, in the preferred embodiment, it is formed with a cylindrical member coupled to the one-way air flow conduit. The other airflow passageway is adapted to be detachably coupled to an oxygen source. A pressure openable closure permits pressure within the interior region of the resuscitation mask to be released by a further conduit.
