A leg spring pretensions the two clip parts into an initial rotation position. The pivot bearing of the two clip parts is formed by a bearing sleeve and the winding body of the leg spring is arranged at least in part inside the bearing sleeve. ## Claims ### Claim 1 A surgical clip comprising: two rotatably connected clip parts, each clip part having a clamping arm, an operating arm, and an interposed annular section with an opening; and a pivot bearing formed by a bearing sleeve, the bearing sleeve disposed at least partially inside the opening of the two rotatably connected clip parts; and a leg spring which pretensions the two clip parts into an initial rotation position, wherein a winding body of the leg spring is arranged at least in part inside the bearing sleeve. ### Claim 2 (depends on 1) The surgical clip according to claim 1, wherein the openings of the two clip parts are circular and the bearing sleeve is fitted into both openings and is pivoted therein. ### Claim 3 (depends on 2) The surgical clip according to claim 2, wherein the circular openings of the two clip parts have the same opening diameter. ### Claim 4 (depends on 1) The surgical clip according to claim 1, wherein the bearing sleeve is non-rotatably mounted to one clip part and has a bearing section which is fitted into the circular opening of the other clip part and is pivoted therein. ### Claim 5 (depends on 4) The surgical clip according to claim 4, wherein the bearing sleeve is produced in one piece with one of the clip parts. ### Claim 6 (depends on 4) The surgical clip according to claim 4, wherein the bearing sleeve has a fitting section of non-circular outer cross-section which is non-rotatably fitted into the non-circular opening of one of the clip parts. ### Claim 7 (depends on 1) The surgical clip according to claim 1, wherein the two clip parts are formed from weldable material and the two spring legs of the leg spring are welded to the two clip parts or are welded to both the bearing sleeve which is non-rotatably mounted to one of the clip parts, and to the other clip part. ### Claim 8 (depends on 1) The surgical clip according to claim 1, wherein the two clip parts are formed from non-weldable material and one spring leg of the leg spring is welded to the bearing sleeve which is non-rotatably mounted to one of the clip parts, and the other spring leg engages the other clip part. ### Claim 9 (depends on 1) The surgical clip according to claim 1, wherein the winding body of the leg spring is arranged completely inside the bearing sleeve. ### Claim 10 (depends on 1) The surgical clip according to claim 1, wherein the two clip parts are connected to each other via a push-fit rotary lock, wherein the two clip parts are axially fitted into one another in an assembly rotation position and are axially locked to each other by subsequent rotation towards the initial rotation position. ### Claim 11 (depends on 10) The surgical clip according to claim 10, wherein the annular section of at least one of the two clip parts has two first annular segments which are disposed opposite to each other with respect to the opening, and a respectively interposed second annular segment which is radially set back towards the inside with respect to the first annular segments, and at least the other clip part has a push-fit receptacle which is formed by two side walls which are disposed opposite to each other with respect to the opening and are provided with circumferential grooves, wherein in the assembly rotation position, the two second annular segments of one of the clip parts are fitted into the push-fit receptacle between the side walls of the respective other clip part and through subsequent rotation, the first annular segments of the one clip part engage the circumferential grooves of the other clip part, thereby locking the two clip parts to each other in a direction opposite to the fitting direction. ### Claim 12 (depends on 1) The surgical clip according to claim 1, wherein the two clip parts are axially held together by the bearing sleeve, one end of which has an annular shoulder and the other end of which has a rivet head that is bent to the outside. ### Claim 13 (depends on 1) The surgical clip according to claim 1, wherein the flat inner surfaces of the annular sections of the two clip parts, which face each other, lie on top of each other. ### Claim 14 (depends on 1) The surgical clip according to claim 1, where the clip parts, pivot bearing and leg spring comprises an aneurysm clip. ### Claim 15 A surgical clip, comprising: two rotatably connected clip parts, each clip part having an annular section aligned with an opening, each annular section and opening disposed between a clamping arm opposite an operating arm; a bearing sleeve disposed within the opening of one of the clip parts or integrally formed as part of one of the clip parts, wherein the bearing sleeve is also disposed within the opening of the other clip part; and a leg spring pretensioning the two clip parts into an initial rotation position, wherein a winding body of the leg spring is arranged at least partially inside the bearing sleeve.
