A skin retention device 10 for a medical jet-injection unit 20 comprises a contact face provided with adhesive 12 in the area surrounding and close to the injection opening(s) 11 of the nozzle 21 which ensures god contact between the nozzle 21 and the skin 30 of a subject in the area chosen for an injection. Consequently the injection force can be lowered dramatically. In case of two-stage jet-injections, the initial injection force can be lowered because the skin retention close to the injection point significantly reduces the energy consuming elastic expansion of the skin 30 in the injection area, and the second injection force can be lowered because of the high degree of fixed positioning of the injection opening of the nozzle 21 relative to the injection channel in the skin 30 made during the initial injection stage. Thus a high degree of injection safety is achieved, minimizing the risk of whet shots, while skin lift and lower injection force decreases the risk of damage of the underlying tissue.

Disclosed is a device for directional drilling including a drill head mounted on a drill column. A driving device applies an axial driving force to the drill column.
