Mechanised bone cement delivery system with a valve that closes to stop the flow of pressurized cement

A device for injecting bone cement into bone, said device including:

• a reservoir, said reservoir having opposed proximal and distal ends, said reservoir tube having a void space located between the ends for holding bone cement;
• a plunger movably mounted to said reservoir, said plunger having a distal end disposed in void space of said reservoir and a proximal end spaced from the distal end, wherein said plunger is mounted to said reservoir so as to be selectively advanced towards the distal end of said reservoir in order to force bone cement out of the distal end of said reservoir;
• a drive assembly connected to the proximal end of said plunger, said drive assembly configured to, when actuated, advance said plunger distally through said reservoir;
• a connector having an extension tube that is connected to the distal end of said reservoir, and at least one component for releasably engaging a cannula that is configured for insertion into living tissue;
• a valve located along the extension tube for regulating flow of bone cement;
• and
• a controller connected to both said drive assembly and said valve for regulating both said drive assembly and said valve and configured to:
• when activating said drive assembly, open said valve;
• and
• when deactivating said drive assembly, close said valve so as to block the flow of bone cement.
