Bone pressure-reducing needle

Abstract

The invention relates to a bone pressure-reducing needle comprising a needle point, self-tapping threads, a needle rod and a handle. The middle of the handle and the back end of the needle rod are connected in a T shape, the front part of the needle rod is provided with the self-tapping threads, and the needle point arranged at the front ends of the self-tapping threads is a triangular needle point. Because the needle point is in a triangular cone shape, the bone pressure-reducing needle is easily penetrated into a bone, the self-tapping threads behind the needle point can enhance the propulsive force of the needle point so that the bone pressure-reducing needle smoothly drills on the bone during rotation, and the bone pressure-reducing needle is penetrated by clockwise rotation and is withdrawn by counterclockwise rotation. The bone pressure-reducing needle can drill a smooth and rounded pressure-reducing pore on the bone with raised internal pressure under the pressure and the slow rotation state of the handle in a straight line shape so that overhigh pressure in a bone cavity can be discharged out of the pore, the bone has balanced external and internal pressure, and the pressure in the bone returns to normal. The invention has the advantages of simple and reasonable structure, safe and convenient use, good pressure-reducing effect, small wound, rapid recovery after operation and the like, fills the blank of special bone pressure-reducing appliances for needle and knife operations and is suitable for all-level hospitals and clinics.

Description

technical field [0001] The invention relates to a needle, in particular to a needle tool for treating osteoarthritis by alleviating the increase of intraosseous pressure. It is a special needle in needle-knife surgery and belongs to the field of medical equipment. Background technique [0002] Human bones can be caused by many reasons to increase intraosseous pressure. The clinical manifestation is long-term pain in joints, and it is difficult to take anti-inflammatory drugs to be effective. Drilling treatment is often used in surgery to reduce the internal pressure of bones, which can restore the intraosseous pressure to normal and relieve pain. But because there is no special tool at present, can only adopt electric drill drilling or thicker Kirschner wire to carry out operation, but the damage that electric drill drilling causes to patient is bigger, and Kirschner wire is difficult to get out of hole again, also can There are problems such as high environmental requiremen...

Problems solved by technology

But because there is no special tool at present, can only adopt electric drill drilling or thicker Kirschner wire to carry out operation, but the damage that electric drill drilling causes to patient is bigger, and Kirschner wire is difficult to get out of hole again, also can There are problems such as high environmental requirements and high postoperative infection rate, and high requirements for medical personnel, making it unsuitable for general hospitals to carry out
