Abstract
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.
Claims15
A closed bone cement mixing and dispensing system, comprising:
- a double-barrelled syringe device having:
- a first barrel with a first plunger, said first plunger having a shaft that is at least partially threaded, said first plunger actuatable to move along said first barrel;
- a second barrel with a second plunger actuatable to move along said second barrel;
- a locking mechanism including a cam and having first and second relative positions, wherein in said first relative position said cam engages said shaft of said first plunger to allow twist-actuation of said first plunger, and in said second position said cam does not engage said shaft of said first plunger to allow push actuation of said first plunger.
A closed bone cement mixing and dispensing system, comprising:
- a double-barrelled syringe device for delivering bone cement having a first barrel, a second barrel, and a valve,
- wherein said first barrel initially contains a first bone cement component and said second barrel initially contains a second bone cement component, and
- wherein said valve allows for the first and second barrels to be in fluid communication to allow mixing, and
- wherein said system further comprises an outlet connected to said valve for dispensing bone cement formed in one or both of said barrels by mixing the bone cement components.
