A bone cement mixing device has a canister which is modular in design and constructed from a transparent material. The mixing device further has a mixing head assembly having a crank which is operatively coupled to a mixing blade via a gear train. The gear train is configured to drive the mixing blade in a reciprocating manner including the varying of the angular velocity, direction of travel, and angular distance of travel of the blade while the crank is rotated at a constant velocity and direction. The mixing blade has a fluid passage defined therein which allows the liquid cement component to be delivered at various locations within the mixing chamber of the canister. A method of mixing bone cement is also disclosed.

Bottle cap removal device with an opening therein to receive a bottle cap, including a top and a base which combine to provide an envelope for the bottle cap removal device and including an annular member and a surface opposed to the annular member operative to apply increased gripping forces on the bottle cap upon relative rotation between the annular member and bottle cap, thereby efficiently removing the bottle cap.
