DEVICE FOR INTRODUCING BONE-PLASTIC MATERIAL

摘要

The invention relates to medicine, and specifically to traumatology, orthopedics and neurosurgery, and may be used for introducing bone-plastic materials when fixing bone defects resulting from vertebral fractures. A device for introducing a bone-plastic material is capable of being disassembled and contains a funnel, a guide and a pusher. The upper portion of the guide is threaded for screwing the funnel onto same, and a handle, which is affixed to the guide via a bushing and screw, is capable of being moved to a set level. A pusher is installed in the guide, said pusher protruding 5mm past the lower edge of the guide. A lower end of the guide is provided with a threaded portion having a thread pitch of 2.5-3mm. The device allows for reliably securing the position of an instrument in a wound, as the device may only be removed by unscrewing same. The present invention eliminates the possibility of slipping and injuring a vertebra by means of providing an inner threading in the vertebral canal, which allows for later introducing transpedicular screws via a low-invasive method without additional effort and complications. The proposed invention is made of high-strength, hypoallergenic, high-quality modern materials with the use of modern technologies.
