Bone Cement System And Related Assemblies And Methods

A disposable assembly configured to be coupled to a capital assembly to form a bone cement system, the disposable assembly comprising:

• a shell;
• a mixing chamber disposed within the shell;
• a cover removably coupled to the shell to enclose the mixing chamber within the shell;
• a shell coupler coupled to the shell and configured to be removably coupled to a base coupler of the capital assembly;
• a driven shaft rotatably coupled to the shell and configured to receive torque from a drive shaft of the capital assembly with the shell coupler coupled to the base coupler;
• and
• a paddle disposed within the mixing chamber and coupled to the driven shaft,
• wherein the paddle is configured to be rotatable within the mixing chamber to form bone cement with the cover enclosing the mixing chamber and the shell providing a sterile barrier.

A disposable assembly configured to be coupled to a capital assembly to form a bone cement system, the disposable assembly comprising:

• a shell defining a recess;
• a mixing chamber disposed within the shell;
• a cover removably coupled to the shell to collectively provide a sterile barrier to the mixing chamber within the shell;
• a shell coupler coupled to the shell and disposed within the recess, wherein the shell coupler is configured to be removably coupled to a base coupler of the capital assembly;
• a driven shaft rotatably coupled to the shell and configured to be rotated by a drive shaft of the capital assembly;
• and
• a shroud removably coupled to the shell to aseptically seal the recess.
