Title:
MIXING DEVICE AND METHODS FOR MAKING BONE CEMENT
Document Type and Number:
WIPO Patent Application WO/2020/252296
Kind Code:
A9
Abstract:
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.
