Abstract
For the application of bone cement, the cement must be ejected with maximum uniformity. The proposed device comprises a cylinder (10) including a distal ejection nozzle (11), said cylinder with its proximal end (12) being adapted for mounting on a displacing unit (20) for displacing a piston (13). The displacing unit (20) comprises gear means (21, 22) for converting the rotary movement of a driving journal (23) into the linear displacing movement of a driven plunger (14). The piston (13) is adapted to be connected with the driven plunger (14). In the vicinity of the driving journal (23) the displacing unit (20) comprises adapter means (30) for detachable assembly with a pneumatic drilling machine (40).
