Electrosurgical instrument elongated suction tip for electrosurgical instruments , and a method of adjusting the axial position of the suction tip of the electrosurgical instrument

摘要

Electrosurgical instrument ( 1 ) has a hollow elongated body with attached electrode means ( 3 ) ( 2 ) . Suction means comprises a hollow interior extending suction channels of the elongated body ( 2 ) ( 27 ) , a first suction port is disposed opposite to the first means ( 3 ) ( 40 ) , communicating with the vacuum source I have a second suction port with the suction tube ( 11 ) ( 41 ) , the suction tip section ( 6 ) . Suction tip ( 6 ) has connecting end portion ( 76 ) , this connecting end , the second engagement means ( 25 ) provided in the hollow elongated body ( 2 ) and for engaging and a first engagement means ( 78 ) . First engagement means ( 78 ) and the second engagement means ( 25) , longitudinal axis (A in axial position suction tip of the suction tip relative to the first means ( 3 ) ( 6 ) ( 6 ) as can be adjusted in response to movement of the suction tip along around and / or the axis (A) (6) of ) , and is formed .
