An elongated electrosurgical instrument, a suction tip for the electrosurgical instrument and method of adjusting the axial position of the suction tip on the electrosurgical instrument

摘要

An elongated electrosurgical instrument (1) 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).
