Abstract

A paste injector gun, especially adapted for injecting bone cement, has first and second mechanical advantages corresponding to different portions of the trigger stroke. The first mechanical advantage is greater than the second such that the first facilitates pressurizing the bone cement and the second facilitates high volume dispensing of the bone cement. The injector gun also includes a pair of U-shaped slots. One of the slots is sized to accept a large cement cartridge and the other slot is sized to accept a small cement cartridge.
