Abstract
A cartridge in which bone cement is mixed and from which the cement is discharged. A blade with plural vanes is disposed in the cartridge for mixing the cement. A piston located in one end of the cartridge is actuated to push the mixed cement out of the cartridge. The blade has plural vanes, one for scraping cement off the side of the cartridge, one for scraping cement off the piston and one for scraping cement off the end of the cartridge opposite the end in which the piston is normally located. The blade is collapsible so that when the piston is actuated the blade compresses to allow the cement in the cartridge to be pushed out.
