Abstract
The invention relates to a spreadable medical instrument, comprising a handle part and at least two spatula elements which are connected to said handle part and, via at least one adjusting mechanism, can be adjusted parallel or at an angle to one another between an initial position, in which the spatula elements rest against one another, and at least one working position. In the working position, the individual spatula elements are spaced at intervals so that they form lateral gaps at least in the distal area, and when the spatula elements are in a working position, these lateral gaps between the spatula elements can be covered almost entirely by swiveling flap elements. In order to produce a spreadable medical instrument that ensures that no soft tissues can penetrate between the spatula elements through the lateral gaps, the invention proposes that the adjusting flap elements of each side are secured on at least one of the spatula elements in such a way that, in the initial position of the spatula elements, they rest in a form-fitting manner on the outside of the other spatula part that is not equipped with the respective flap element.
