DEVICE FOR STORING AND MIXING BONE CEMENT

The invention relates to a device for storing, mixing, and applying polymethylmethacrylate bone cement, and to a method for producing a polymethylmethacrylate bone cement therewith. The device and method separates the processes of pressing out and mixing both in time and in space, rather than simultaneously combining the processes of pressing out and mixing through the use of static mixers, which is common with pasty two-component polymethylmethacrylate bone cements. The liquid, pasty and/or powdery components of the bone cement are mixed in a manually operated mixer into a cement dough before being pressed out in a homogeneous mixture. The press-out force required for dispensing is low and manually operated inexpensive cementing guns can be used. A mobile volume compensation element is used to compensate for volume fluctuations during the mixing process, without any cement dough exiting and without air being drawn into the cement dough.

The outer cylinder receives a cap thereon which hermetically seals the cartridge. The cap includes an outlet pod in which a break-away agitator is installed and a pod for connection of a vacuum pump. In use, a desired vacuum pressure is drawn on the cartridge and the inner cylinder is allowed to be drawn into the outer cylinder while the vacuum is being drawn, whereupon the inner cylinder automatically stops moving relative to the outer cylinder when the desired vacuum pressure is reached. Mixing of the bone cement is then performed under the partial vacuum thereby created. The agitator paddles provide a scraping action against both inner cylinder walls of the telescoping cylinders thereby improving mixing. After mixing, the agitator is broken away, an appropriate nozzle is attached to the cartridge and the cartridge is inserted into a cement gun. The leading portion of the bone cement develops a convex profile when axially advanced through the cartridge and the piston plug includes a tapered protrusion which generally corresponds to the profile of the bone cement. The cap and paddles are also shaped correspondingly to the convex profile developed by the bone cement, resulting in substantially all of the bone cement being squeezed from the cartridge. An air escape passage is also provided to vent air contained within an annular gap between the agitator shaft and the cap upon initial expulsion of bone cement, resulting in the bone cement expelled from the cartridge being essentially free from entrained air.

Calcium phosphate cement kneading apparatus and method for preparing calcium phosphate cement kneaded material

Apparatus and method for mixing and dispensing bone cement

A method and apparatus for mixing bone cement which produces bone cement essentially free of entrained air. The apparatus includes a cartridge having two telescoping cylinders. The outer cylinder receives a cap thereon which hermetically seals the cartridge. The cap includes an outlet port in which a break-away agitator is installed and a port for connection of a vacuum pump. In use, a desired vacuum pressure is drawn on the cartridge and the inner cylinder is allowed to be drawn into the outer cylinder while the vacuum is being drawn, whereupon the inner cylinder automatically stops moving relative to the outer cylinder when the desired vacuum pressure is reached. Mixing of the bone cement is then performed under the partial vacuum thereby created. The agitator paddles provide a scraping action against both inner cylinder walls of the telescoping cylinders thereby improving mixing. After mixing, the agitator is broken away, an appropriate nozzle is attached to the cartridge and the cartridge is inserted into a cement gun. The leading portion of the bone cement develops a convex profile when axially advanced through the cartridge and the piston plug includes a tapered protrusion which generally corresponds to the profile of the bone cement. The cap and paddles are also shaped correspondingly to the convex profile developed by the bone cement, resulting in substantially all of the bone cement being squeezed from the cartridge. An air escape passage is also provided to vent air contained within an annular gap between the agitator shaft and the cap upon initial being essentially free from entrained air.
