Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traditional Chinese medicine clinical medicine, in particular to a chi needle. Background Art
[0002] The chi needle is one of the nine ancient needles, also known as the pushing needle and the lifting needle. According to "The Spiritual Pivot. Treatise on the Nine Needles": "The chi needle is made in the shape of the tip of millet, three and a half inches long, mainly for pressing the pulse to obtain qi and expelling pathogenic factors. Modern chi needles are often made of thick steel wire, and some are made of bone or hard wood. Its characteristic is that the needle tip is blunt and round, and it will not cause puncture damage to the skin and muscles. The chi needle is used to press and acupoint at human acupoints or stimulation points. From the anatomical position, the chi needle only acts on the skin layer, muscle layer, and fascia layer, and does not enter deeper tissues for treatment. Therefore, it does not treat the intervertebral disc tissue buried deep in the skin, muscle, and fascia layers.
[0003] A normal intervertebral disc is wrapped by multiple layers of annulus fibrosus around the central nucleus pulposus. Under the action of long-term continuous pressure, the nucleus pulposus generates pressure on the restricted annulus fibrosus, resulting in the rupture of multiple layers of annulus fibrosus. Eventually, the nucleus pulposus completely breaks through the annulus fibrosus restraint and enters the spinal canal, squeezing the nerve tissue in the spinal canal and causing symptoms. The protruding nucleus pulposus is stuck between the ruptured annulus fibrosus, which also makes it difficult for the annulus fibrosus to heal on its own. Obviously, the ideal treatment idea for intervertebral disc herniation is to reset the protruding nucleus pulposus back to the center of the intervertebral disc and wrap the annulus fibrosus around the nucleus pulposus as much as possible. The part of the ruptured annulus fibrosus without the nucleus pulposus stuck has the condition for re-healing. The re-healed annulus fibrosus will eventually re-wrap and fix the nucleus pulposus in the annulus fibrosus, thus relieving nerve compression and achieving the goal of clinical cure.
[0004] This operation is difficult to perform with traditional chi needles because traditional chi needles are designed to treat the skin, muscle, and fascia layers outside the intervertebral disc. The needle tip of traditional chi needles is spherical, with a diameter too small (about 3 mm), and it is easy to slide on the surface of the protruding nucleus pulposus tissue when touching it, making it difficult to fix it; and the too small diameter may cause too high local pressure, which may damage the surrounding skin, muscle, and nerve tissues.
