Claim Text:
1. A mixer gun system comprising: a removable holder cap configured to separately store two or more components in separate chambers formed therein, the two or more components being selectively releasable through channels fluidly communicating with the separate chambers, the two or more components being constituent materials for a bone cement; a body forming a mixing chamber therein and configured to receive the holder cap, the mixing chamber including at least one opening corresponding with the channels for the separate chambers; a piston disposed within the mixing chamber; and a plunger coupled to the piston and configured to be biased toward the mixing chamber such that when the two or more components are released into the mixing chamber from the holder cap a pressure developed by a biased motion of the plunger and piston infuses the two or more components to form the bone cement and, upon resetting the plunger and the piston, the bone cement is dispensed from the mixing chamber by the same biased motion, wherein the body includes a handle and a trigger is pivotally coupled to the handle for releasing the plunger for the biased motion and a switch is pivotally coupled to the body, the plunger including a threaded portion that engages the switch to prevent the biased motion of the plunger, the trigger being configured to activate the switch to release the plunger to provide the biased motion.
