1. A device for mixing and containing fumes for a bone cement component comprising:
a vial holder comprising a body having an inner surface that defines a cavity, the vial holder comprising a distal portion having a threaded outer surface, the vial holder comprising an opening that extends through the distal portion and is in communication with the cavity; a vial positioned within the cavity; a container comprising a proximal chamber and a distal chamber, the body being positioned within the proximal chamber, a first portion of the distal chamber being defined by a threaded inner surface that is configured to engage the threaded outer surface to move the vial holder axially relative to the container, the container comprising an outer surface that defines a ledge, the container comprising a vial-breaking device disposed therein and an elastomeric seal having a first surface and an opposite second surface, the seal being positioned such that the vial-breaking device extends through the first and second surfaces, the seal being configured to form a seal against an unthreaded inner surface that defines a second portion of the distal chamber so as to prevent fumes from escaping from the container; and a mixing vessel comprising a port and a syringe that is in communication with the port, the syringe comprising a plunger that is movable within the syringe, the mixing vessel comprising a second threaded inner surface that engages a second threaded outer surface of the container to move the container axially relative to the mixing vessel between a first orientation in which the ledge is spaced apart from the plunger and a second orientation in which the ledge engages the plunger to move the plunger relative to the syringe and drive contents of the syringe out of the port. |
