Abstract

A medical instrument comprises a tubular body, housing at least one injection needle with a radially outwardly directed tip portion in an axially undisplaceable manner. A control element serves for deploying the tip of the injection needle out sideways from the tubular body. It is proposed that the control element is housed in the tubular body in an axially displaceable manner, and that said element it in operative connection with the at least one injection needle in such a way that, in a first axially displaced position, the outwardly directed tip portion of the injection needle is fully retracted in the body and, in a second axially displaced position, at least the tip of the outwardly directed tip portion is pressed sideways out from the tubular body (FIG. 5).
