The rotatable base cap with an internal gear is attached to and is rotatable relative to the main housing. The mixing blade has a plurality of prongs extending from a shaft. The prongs are in the mixing chamber and the shaft extends through an opening in the main housing to inside the rotatable base cap. The gear mechanism has at least one gear, each of the at least one gears is connected to or intermeshed with the internal gear of the base cap and the gear of the shaft end.

A liquid dispersion device of the present invention includes at least one liquid flow member attachable to a rotary shaft. The liquid flow member includes at least one tubular suction portion extending along the rotary shaft and including a suction port at a lower end thereof, and at least one ejection portion extending in a direction inclined with respect to the suction portion and having one end that is in communication with an upper end of the suction portion and the other end that includes an ejection port. An angle .sub.2 between a horizontal direction and an axial direction of the ejection portion at an opening surface of the ejection port is 90.sub.220 with respect to the horizontal direction.

A mixing device and methods for making bone cement. A piston (156) of the mixing device is located in a first region (158) of a chamber (112) such that a mixing paddle (154) rotates to mix bone cement components at a first pressure to make a bone cement mixture. The piston (156) is moved passed an inlet opening (136) to be located within a second region (160) of the chamber (112) to compress the bone cement mixture to a second pressure greater than the first pressure to compress the bone cement mixture and make the bone cement. The bone cement may be transferred to a delivery device. The mixing device may include features that automatically initiate the compression and transferring phases after completion of the mixing phase, and further include features that automatically terminate the operational cycle. A three-step intuitive workflow utilizing the mixing device to improve efficiency in the surgical suite is also disclosed.

A mixing shaft has a tool holder rotatable about a tool axis and at least one mixing blade. The tool holder includes at least one recess in which a mixing blade portion of the at least one mixing blade is received. A clamping member inserted into the recess is configured to fix the mixing blade portion in the recess. The recess includes a first and a second recess portion. The mixing blade portion is arranged in the first recess portion and the clamping member is arranged at least partly in the second recess portion, wherein the first recess portion and the second recess portion are arranged adjacently in one plane extending perpendicularly to the tool axis.
