Description

technical field

[0001] The invention belongs to the technical field of medical devices, in particular to a bone cement mixer and a mixing mechanism thereof. Background technique

[0002] At present, there are various mixing methods for bone cement used in percutaneous vertebroplasty and percutaneous kyphoplasty. Injection into the vertebral body. However, this method will volatilize the pungent odor, which will affect the intraoperative experience and physical health. At the same time, the transfer of bone cement will waste the operation time, and it is easy to cause the bone cement to harden without bolus injection. Therefore, there is a bone cement mixer, which can realize the integration of bone cement mixing and advancing, that is, both the stirring and advancing process of bone cement are completed by one device.

[0003] Existing bone cement mixers include a cartridge, a push rod, a gun nozzle and a stirring rod, wherein the inside of the cartridge is a space for con...
