  • Patent number: 11160594
    Abstract: A device for producing a bone cement dough from a monomer liquid and a cement powder and dispensing the bone cement dough. The device includes a cartridge holding the cement powder in an internal space. A monomer receptacle screws onto the cartridge, forms a chamber, and has a plunger with a passage that is permeable to gases and the monomer liquid but is impermeable to the cement powder and that connects the internal space to the chamber. The plunger tightly closes the internal space with the exception of the passage. A gas supply opening is arranged in the wall of the monomer receptacle. A monomer liquid container holds the monomer liquid and is located in the chamber. An opening facility opens the container, and closes the gas supply opening before opening the container. Also provided is a method for producing and dispensing the bone cement dough.

    Abstract: A system for bone cement includes a vial holder configured for receiving a vial and including a holding structure for maintaining the vial in the vial holder. The vial includes a monomer component for bone cement. A holder chamber is configured to receive and secure the vial holder. The vial holder is advanced toward a vial-breaking device for breaking the vial and releasing its contents into the holder chamber past the elastomeric seal. Once the vial holder is advanced further the elastomeric seal is deformed to form a seal and prevent fumes produced from escaping from the device.

  • Patent number: 8657482
    Abstract: A system and method for mixing bone cement. The components forming the cement are contained in a cartridge. A motorized device, such as a surgical handpiece, rotates a blade in the cartridge that mixes the cement. The current drawn by the motor is monitored. The current draw is evaluated to determine the viscosity of the cement. If the current draw indicates that the cement is at the target viscosity, the mixing may be terminated. A low current draw measure may be interpreted as an indication that the cement is of low viscosity and that it may be necessary to continue the mixing process.
