Abstract

A device for disconnection of a connecting device between an implant (2) and a device (12) connectable thereto, which coupling device is of the type incorporating a first and a second coupling part (6 and 11, resp.), one of which parts (11) in coupling position being elastically retained in a recess provided in the other one of the parts (6), said recess having a depth permitting the second coupling part to project into it to coupling position and where the coupling parts (6, 11) in coupling position are arranged with mutual end-to-end contact and substantially in the axial extension of each other, thus that they are mutually rotatable about a substantially common axis, whereby at least one of the coupling parts (6, 11) is provided with at least one member (19), which together with the other coupling part (11, 6) in at least one mutual rotational position for the two coupling parts, have a total added axial longitudinal measure, which gives the part introduced in the recess a clearance to the other coupling part in interconnected position, and which together with the other coupling part in at least one other mutual rotational position have an overall added axial longitudinal measure, which does not permit the coupling parts to be interconnected, whereby the coupling parts without axial influence upon the implant are brought apart during the mutual rotation of the coupling parts to said at least one other mutual rotational position.
