Aneurysm clip

Aneurysm clip comprising:

• two rotatably connected scissors-shaped clip parts, each having one clamping arm and one operating arm, the two clip parts being rotatable in a working rotation range between a closed and an open end position each of the two clip parts having a bottom plate, an axially open receptacle with a two oppositely disposed pivot guide sections on the outer periphery and respectively interposed assembly recesses, the two clip parts each comprises two pivot bearing sections, disposed opposite to each other with respect to the open receptacle, for the pivot guide sections of the respective other clip parts, wherein the pivot bearing sections of the second clip pat are frothed as guiding grooves, and in the assembly rotation position, the two clip parts are axially fitted into one another with two assembly recesses between the two pivot bearing sections of the respective other clip part and are transferred, by a subsequent rotary motion, into the working rotation range in which the pivot guide sections of the first clip part engage in the guiding grooves of the second clip part;
• a closing spring is disposed in a through-hole which is formed by bores of the two clip parts, which the bores are being centered with respect to an axis of rotation , the two clip parts being pretensioned into the closed position by the closing spring;
• and
• a push-fit rotary lock connecting the two clip parts to each other, the two clip parts being axially inserted into one another in an open assembly rotation position, the position being disposed outside of the working rotation range, the clip parts are axially locked to one another by subsequent rotation into the working rotation range.
