System, device and method for delivery of biomaterials for fracture fixation

The invention relates to a delivery system, device and method for delivering biomaterials for fracture fixation (including augmented fixation), in particular, for delivery of bone cements. The mixingsystem ensures the biomaterial only commences setting upon extrusion from the mixer, cannula or during injection through an appropriate internal fracture fixation device, allowing for rapid closing bythe surgeon. The system also permits the surgeon to cease injecting the cement for an extended period of time before continuing the injection in another area using the same cartridge, through the simple removal of one mixer and attaching another in its place. The invention also provides a method of delivery of biomaterials to a desired implantation site. 本发明涉及用于递送用于骨折固定术(包括增强固定术)的生物材料、特别是用于递送骨黏合物的系统、装置和方法。本混合系统确保了生物材料只有在从混合器、插管挤出时或者在通过适当的内部骨折固定装置注射过程中才开始凝固，允许外科医生快速关闭。本系统还允许外科医生停止注射黏合物延长的时间段，然后通过简单的移除个混合器并且将另个混合器附接到其位置而在另区域中、使用同个盒继续注射。本发明还提供了将生物材料递送到预期植入部位的方法。
