Device and method for mixing and dispensing a bone cement mixture

摘要

In at least one embodiment of the present invention, a device for mixing and dispensing a bone cement mixture is provided. The device comprises a first chamber and a second chamber. The first chamber is for containing a first bone cement component. The second chamber is for containing a second bone cement component. A valve is in fluid communication with the first and second chambers. A first and a second plunger are respectively within the first and second chambers and are configured to actuate within their respective chambers. When the valve is in a first position actuating the first plunger advances the first bone cement component into the second chamber to form the bone cement mixture.
