AN ELECTROSURGICAL INSTRUMENT AND ELECTROSURGICAL CONDUCTIVE ELECTRODE FOR USE WITH THE INSTRUMENT

摘要

An elongated electrosurgical instrument (1) serves to at least cutting tissue of a patient during surgery by application of electrical energy supplied from an electrosurgical generator to a surgical site. The electrosurgical instrument has a hollow elongated main body (2) with an electrode means (3). Suction means comprises a suction channel (27) extending inside the hollow elongated main body (2), a first suction port (40) arranged facing the first means (3), a second suction port (41) provided with a suction tubing (11) in communication with the vacuum source, and a suction tip (6). The suction tip (6) has a coupling end part (76) that has a first engagement means (78) for engagement with a second engagement (25) means provided on the hollow elongated main body (2). The first engagement means (78) and the second engagement means (25) are configured so that an axial position of the suction tip (6) in relation to the first means (3) is adjustable in response to movement of the suction tip (6) about and/or along a longitudinal axis (A) of said suction tip (6). The invention provides the possibility of combining separate components into plural different electrosurgical instruments and thus offers the surgeon a hitherto unknown possibility of creating his/her favourite tool with excellent suction properties.
