Improved dilation device for surgical protocols involving the treatment of fractured or diseased bone

摘要

The present invention is an apparatus 12 used to compress the bones and bone marrow (also called medulla or columnar bone) of reticulated tissue against the internal cortex, with or without bone fractures. The instrument consists of an expandable non-expandable instrument that can be inserted into such bones. The body forms a cavity in the reticular bone and has a shape and size that can press at least a portion of the reticular bone to restore the original location of the outer medulla when the bone is broken or dislocated. This mechanism prevents excessive pressure on the external medulla bone. The wall of the instrument is properly inflated to allow for optimal pressure on all bone marrow. The instrument is foldable and can be quickly inserted into the bone. This device may be manufactured to include a suction catheter 16. This therapeutic material may be coated. The main purpose of the instrument is to form or enlarge a cavity or passageway in the bone, which can be used especially for the vertebrae, but not limited thereto. Another important purpose is to administer therapeutic substances to bone in an improved way.
