BONE CEMENT MIXING AND DELIVERY SYSTEM WITH AUTOMATED BONE CEMENT TRANSFER BETWEEN MIXER AND DELIVERY DEVICE AND METHOD OF MIXING AND AUTOMATED TRANSFER OF BONE CEMENT BETWEEN MIXER AND DELIVERY DEVICE

摘要

A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a mixing paddle and a mixing shaft connected to the mixing paddle. A motor operatively engages the mixing shaft to rotate the mixing shaft and the mixing paddle to mix the components in a mixing chamber. The motor also operatively engages a transfer mechanism. After a predetermined mixing period has elapsed, the motor automatically actuates the transfer mechanism to transfer the mixture to a delivery device. The mixture is then delivered to a target site, such as a vertebral body of a patient or other anatomical site.
