Abstract: The present invention relates to a bone cement mixing apparatus for mixing a quantity of monomer from a monomer dispensing apparatus with a quantity of bone cement in the presence of a vacuum. The mixing device includes a bowl, a lid connectable to the bowl, a luer lock connectable with a luer from the monomer dispensing apparatus, a crank rotatably connectable to the lid and extending through the lid, a blade off-set positioned inside the bowl and non-concentrically connected to the crank, and a vacuum source connectable to the device.

Abstract: A pressurizer apparatus for substantially sealing proximal ends of prepared medullary canals during pressurization with a cement injection device, comprising a body portion including dissimilar surfaces on opposed ends formed to engage the proximal ends and with each surface including dissimilar surfaces and a dissimilar-surface channel extending between the dissimilar surfaces and wherein the dissimilar-surface channel is sized and adapted to receive at least a portion of the cement injection device therein from either end of the channel

Abstract: A surgical instrument case suitable for autoclaving and instrument presenting to the surgeon during surgery comprising a container formed to include an interior region, cradle means for holding a variety of surgical instruments attached to the bottom of the container to be in the interior region; and a top. The top, when it is open, provides support means for propping the instrument case at an acute angle to the horizontal to provide easy access to the instruments by the surgeon while minimizing handling, the top being hingedly attached to the container. The cradle means is formed to include notches of various size to accommodate instruments of various sizes in laterally spaced-apart, upwardly extending positions when the instrument case is opened and propped up.
