ABSTRACT:
A surgical endoscopic instrument has a stem portion and a handle portion and an operating insert axially extending through both of those portions. The insert carries at least one hf operating electrode which can project beyond the distal end of the stem portion. An insulated electrical conductor extends along the length of the operating insert to connect the electrode to a plug subassembly forming the proximal end of the operating insert. The plug subassembly is electrically connected to a removable jack with a connection cable leading to an hf energy source. The operating insert is rotatably supported inside the implement and the jack is non-rotatably coupled to the plug subassembly which is itself non-rotatably linked to the operating insert.
