Abstract:
A bipolar endoscopic instrument comprising a tubular stem, wherein a distal end of said tubular stem supports two jaws, said jaws being pivotable relative to one another, a proximal end of said tubular stem has a bipolar hf plug inserted therein at an acute angle to a push/pull wire, said plug applying a bipolar output of a high-frequency (hf) voltage source into the inside of said instrument, an inserted end of said hf plug being shaped such that the plug contacts are axially insulated from each other and each plug contact touches an electrically conducting contact element inside the instrument which, in turn, is connected in electrically conducting manner to one of said two jaws, wherein a unit (6, 6â€²) is present inside the instrument (1) and comprises the two contact elements (8, 9, 8â€², 9â€²) and an insulator (7, 7â€²) electrically separating the contact elements (8, 9, 8â€², 9â€²), said unit (6, 6â€²) and the hf plug (10) being designed and mounted in the instrument (1) such that the hf plug (10) engages the insulator (10) and such that a particular plug contact (12, 13) of the hf plug (10) touches a particular contact element (8, 9, 8â€², 9â€²).
