Abstract:
Medical instrument, especially for use in surgery, comprising two parts which can be joined to each other; with a coupling sleeve which is joined to one of the two parts of said instrument, and a coupling shank which is formed from the other part of the instrument and can be fixed inside the coupling sleeve, where said coupling sleeve and the coupling shank can be joined to each other in a non-positive fit by at least one coupling element arranged inside a guide cage and where the said coupling element is principally slidable in an axial direction only and the coupling is provided with only one spring element, characterized in that the coupling element is in contact with oblique contact members of the coupling sleeve and the coupling shank, and that the angle (alpha) between the center axis of the coupling sleeve and the oblique contact member of said coupling sleeve is larger than the angle (beta) formed between the center axis of the coupling shank and the oblique contact member of said coupling shank.
