<p>An apparatus which is particularly useful for the mixing of hydroxyapatite cement comprises a syringe body (10) within which a plunger (5) is slidably and sealingly located for expelling the syringe contents, the plunger having an axial passageway and the shaft (2) of an agitator (4) extending therethrough. The agitator has a head portion (25) designed to cause materials (8) contained in the chamber defined between the inner end of the plunger and the syringe interior to be mixed when the actuator is agitated by manual operation of the agitator shaft where it is accessible outside of the plunger. To facilitate dispensing of the mixture, the apparatus can be received in a support frame (60) having a turnscrew (72) at one end enabling the plunger to be operated with mechanical advantage. A removable end cap (16) seals the mixing chamber (8) during mixing and the mixture can be dispensed through an elongate tube into limited access locations.</p> |
