Disclosed is a positioning device (1) for a medical catheter (14) to be positioned in a bodily orifice or cavity, said device containing an elongated tubular or sleeve-type catheter receiving member (11), one end of which receives the catheter (14) to be positioned, an elongated catheter release member (10) which is held inside or outside the catheter receiving member (11) and which can be displaced in the longitudinal direction of said member and a motion mechanism comprising a motion conversion device (2 to 9, 12), by means of which the catheter receiving member (11) and the catheter release member (10) can be displaced relative to one another in the longitudinal direction of the device, thus releasing the catheter (14) from the catheter receiving member (11); the motion conversion device (2 to 9, 12) has an actuating member (4, 5), by means of which motion that is carried out transversely to said longitudinal direction of the device or pivoting motion can be converted into longitudinal motion running in the longitudinal direction of the device. |
