The invention relates to a device for injecting bone cement. The aim of the invention is to improve such a device so that the direction of issuance of t he bone cement, once the cannula has been introduced, can be controlled to a certain extent. To this end, the inventive device is provided with a radial outlet opening (5) on the front end of the cannula (3). Since the cannula (3 ) is introduced by way of a guiding wire (1), it has an opening (4) at its fro nt end which must be closed by a ball (15) before the bone cement is injected. Said ball (15) is introduced by means of a plunger (16). The handle (17) of the cannula has an asymmetric shape so that the position of the radial openi ng (5) is always known even when the cannula (3) is introduced. |
