| description | An electrosurgical instrument for the treatment of tissue via an electrode assembly is disclosed having at least one active electrode and an aspiration system for configured to collect aspirated materials and to remove those aspirated materials from a surgical site while preventing the materials from melting and thereby clogging the aspiration system. In at least one embodiment, the aspiration system may include an internal aspiration collection chamber positioned at a distal end of the instrument to collect aspirated material and insulate the aspirated material to prevent the aspirated material from melting within the aspiration system and thereby clogging the aspiration system. The internal aspiration collection chamber may also be subjected to reduced heating from the active electrode by limiting the exposure of the internal aspiration collection chamber to a minimally sized support arm extending from active electrode to the channel of the aspiration system in the electrosurgical instrument shaft. |
