An electrosurgical method and apparatus for coagulating by fulguration where the electrical discharge is established through a formation of flowing inert gas where the formation may either be a diffuse blanket of the flowing gas or a well defined column thereof.

Electrosurgical method and apparatus for establishing an electrical

A single or multichannel electrical connector including a male connector having at least two prongs depending resiliently from a base, the prongs each having defined in the outer edge thereof a notch with at least one of the notches having at least one conductor exposed at the bottom portion of the notch, the conductor extending internally through the prong, the prongs also having end portions with outwardly facing mutually inclined surfaces, the male connector being adapted to fit a female connector having an opening defined therethrough and configured to receive the prongs with the sides of the notches engaging the front and back endwalls of the female connector adjacent the opening and the connector in the bottom of the notch engaging a contact in a sidewall of the opening in the female connector such that the male connector may be inserted by engaging the opposed inclined planes of the prongs within the opening of the female connector, deforming the prongs towards one another to pass through the female connector thereupon again expanding the prongs to bring the contact of the female connector into engagement with the conductor of the male connector with the notches engaging the front and back end walls of the female connector to secure the male connector therein. In the event more than one conductor is provided in a prong, the prong may be formed of independent sections.

Electrical connector

A single or multichannel electrical connector including a male connector having at least two prongs depending resiliently from a base, the prongs each having defined in the outer edge thereof a narrow notch with at least one of the notches having at least one conductor exposed at the bottom portions of the notch, the conductor extending internally through the prong, the prongs also having end portions with outwardly facing mutually inclined surfaces, the male connector being adapted to fit a female connector having an opening defined therethrough the configured to receive the prongs with the sides of the notches and the connector at the bottom of the notch engaging a protruding contact in a sidewall of the opening in the female connector such that the male connector may be inserted by engaging the opposed inclined planes of the prongs within the opening of the female connector, deforming the prongs towards one another to pass through the female connector thereupon again expanding the prongs to bring the contact of the female connector into engagement with the conductor of the male connector with the notches also engaging the front and back end walls of the female connector contact to secure the male connector therein. In the event more than one conductor is provided in a prong, the prong may be formed of independent sections.
