Abstract
An inserter for the positioning of an intrauterine device in the uterus, which inserter includes a plunger, a handle attached to the plunger, a string for the removal of the IUD, a locking device to lock the string in such a way that the IUD remains immobile in relation to the plunger, and a protective tube around the plunger. The protective tube is arranged in relation to the plunger in such a way that it can be pushed, at the forward end that goes into the uterus, past the plunger at distance (L) , which corresponds substantially to the length of the IUD assembled for insertion. The stop members ensure that the front edge of the protective tube is stopped in a configuration in which the hemispherical tips of the wings of the transverse member of a T-shaped IUD remain partly uncovered by the protective tube, but the wings nevertheless remain pressed against each other.
