An electrosurgical instrument with electrode, suction, optional irrigation and means to bend the distal part of the surrounding suction tube is described. A distal part of the suction tube (around the electrode) has two members, whereas one member can be engaged inside the other-to various degrees- in order to control the length of the suction tube and its relation to the tip of the electrode. Means to fixate the electrode within the suction tube are described. Also described are means to evacuate smoke, blood, irrigation anticoagulant fluid and debris via a suction tube to a separation chamber and evacuation of the gaseous portions by a vacuum machine. The separation chamber serves as a blood collection container (the blood could then be re- infused to the patient!). Irrigation means of isotonic fluid with blood-anticoagulant combined with the suction are described. Combination of the various functions and options could be utilized for building various useful surgical instruments. |
