Abstract

The invention proposes a bone cement mixer and its mixing mechanism, which belong to the technical field of medical devices. The bone cement mixer includes a medicine storage part, and the medicine storage part has a first chamber, and the first chamber is used to accommodate medicine. The bone cement mixing mechanism includes a stirring part, a connecting part and a moving part. The stirring part is located in the first chamber and is used for stirring the medicine. The connecting part is snap-connected with the stirring part. Inside the connecting hole of the stirring element, the connecting block is fixedly arranged at one end of the elastic part. The connecting block has a first supporting inclined surface, the first supporting inclined surface is in contact with the stirring element, the moving element is slidably connected with the connecting element, and the moving element has a constraining portion. The part is in contact with the connection block, and the movement of the moving part on the connection part drives the contact and separation between the restraint part and the connection block, so as to realize the imposition and release of constraints on the deformation movement of the elastic part. The invention improves the efficiency of vertebroplasty operation.

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...
