The Bone Decompression Needle is a kind of medical device, whose structure consists of the needle tip, self-tapping thread and the needle shaft and handle, the middle of the said handle and the back end of the needle shaft are connected in the form of a d-ring, and the needle shaft is equipped with a self-tapping thread at the front part of the needle shaft, and the tip of the needle is a three-pronged tip at the front end of the self-tapping thread. As the tip of the needle is tri-angled conical, it is easy to pierce the bone, the self-tapping thread behind the tip of the needle can strengthen the propelling force of the tip of the needle and smoothly drill holes in the bone during the rotation, clockwise rotation is used to enter the needle, and counterclockwise rotation is used to exit the needle. The pressure of the zigzag handle and the slow rotation of the state of the internal pressure rise in the bone on the drilling of smooth and rounded decompression holes, the bone cavity can be too high pressure from the small holes discharged, so that the internal and external pressure balance of the bone and the pressure in the bone to return to normal. It has the advantages of simple and reasonable structure, safe and convenient use, good decompression effect, small trauma and fast postoperative recovery. It fills the blank of special apparatus for bone decompression for needle knife surgery and is suitable for use in hospitals and clinics at all levels. It is suitable for the decompression treatment of all kinds of high pressure in bone. Such as: knee osteoarthritis, femoral head necrosis, frozen shoulder, old ankle sprain, dizziness, headache, cervical spondylosis, lumbar spondylosis and so on.
