Abstract:
A pivoting device (16; 106) for two pivotally connected two electrically conductive parts (12, 14; 102, 104) of a bipolar electo-surgical device (10; 100) connected wherein the parts have opposed surfaces which are adjacent to each other and wherein the pivoting device (16; 106) and said surfaces (26, 28; 122, 130) of the two parts (12, 14; 102, 104) are electrically insulated from one of the parts (12, 14, 102, 104), wherein the pivoting device (16; 106) is a screwed joint which comprises a screw (46; 158) having a screw head, and a nut (74; 154), and a first hole (36; 108) in one (12; 102) of the two parts (12, 14; 102, 104) for the recessed accommodation of the screw (46; 158) and a second hole (38; 110) in the other part for the recessed accommodation of a nut (74; 154) and wherein electrically insulating material is provided at least on surfaces of the screw (46; 158) and nut (74; 154) and/or on surfaces of the holes (36, 38; 108, 110) in the two parts (102, 104) wherein the screw (46; 158) and/or the nut (74; 154) of the screwed joint (16; 106) are.
