Description

Poking needle assembly

Technical Field

The utility model relates to the field of traditional Chinese medicine acupuncture and moxibustion instruments, in particular to a poking needle assembly.

Background

The acupuncture and moxibustion technique is a treasure in the Chinese medicine culture, and is deeply favored by people all over the world with outstanding treatment effect. "the worker wants to do his best, he must first make good use of his apparatus", so that the innovation of acupuncture and moxibustion is desired to have the effect without leaving the acupuncture needle set. The traditional acupuncture treatment can treat diseases such as cervical spondylosis, lumbar spondylosis, scapulohumeral periarthritis, knee osteoarthritis, myofascitis and the like, and has slow effect, so that a patient is difficult to insist. The common character of the diseases is that tendons and knots exist, and the diseases such as 'pressure pain spots', 'induration', 'cord' and the like appear at the meridians, joints, muscles and the like of four limbs due to long-term strain and the like, and the pain and the discomfort of the focus parts of the tendons and knots are mainly clinically shown.

The acupuncture needle in the prior art comprises a luxury needle, a long-hair needle and a poking needle, wherein the luxury needle is a sharp needle with the longest needle body being no more than 250 mm and the largest diameter being no more than 0.4 mm, and is usually used for acupuncture points; the needle body of the elongated needle is as thin as a wheat awn, the length of the elongated needle is generally 167-266 mm, the elongated needle is thick, and the needle tip is pointed. The poking needle is 0.5-2mm in diameter, the needle point is blunt, the poking needle is a special needle tool for stripping and loosening tissue adhesion, and only the poking needle is involved. The traditional poking needle has the defects of painful insertion, complex needle handle and high cost.

Zhang Yunfei in Heilongjiang, which discloses a giant needle (publication number: CN2066741U, published: 1990, 12 and 5), and aims to solve the problem of poor needle poking feeling in the prior art, the giant needle comprises a needle body 1 and a needle point 3, wherein a thin copper wire at the top of the needle body 1 is wound with a stainless steel wire to form a needle handle 2. The needle tip 3 is round. The needle has large stimulation and strong needle feeling, and has special effect on certain severe intractable diseases because the thick needle is not easy to bend and block. And because the needle point is round and not blunt, so that the needle is easy to prick along the skin, and because the needle is long, a needle can penetrate through multiple acupuncture points, so that the effects of dredging the channels and collaterals, regulating the tendons and skin, regulating qi and blood, and opening carbuncles and dredging the embolism can be achieved, and the effect of treating the severe aeipathia is good. The needle application method comprises the following steps: the lower end of the needle body is clamped by the thumb and index finger of the right hand, the needle point is exposed by 14-17 mm, the needle is quickly inserted by aiming at the acupuncture point, then the needle is twisted and penetrated along the skin, the needle feeling is strong, if the needle feeling is not needed, the needle can be slightly lifted and inserted to obtain the needle feeling, and then the needle is taken out. Generally, the needle should be withdrawn slowly without leaving the needle, and the needle hole should be pressed with cotton ball for a while. However, puncturing the skin with a round-headed needle is very painful and the needle insertion experience for the patient is poor.

Anhui congratulations successfully disclose a prickle (publication number: CN101940531A, published day: 2011 1 month 12 days), aiming at solving the technical problems that the handle of the traditional prickle is in a straight line with the needle body and the lifting and inserting manipulation is not easy to be performed during subcutaneous transverse puncturing, the prickle comprises a needle point 1, a needle body 2, a wing-shaped needle root 3 and a Z-shaped needle handle 4, wherein the needle body 2 is in a slender cylinder shape and is made of tungsten steel, and the needle point is in a blunt round shape and is sharp but not sharp; the front end of the needle handle is vertical to the wing-shaped needle root 3, the wing-shaped needle root 3 is a flat plate of 0.5x1.5, and the needle handle is a circular tube. The effect is that the needle handle and the needle body are Z-shaped, the wing-shaped needle root 3 is pinched, and the lifting and inserting method is easy to be carried out when the subcutaneous transverse puncturing method is performed; secondly, the thinner elongated needles are used for deep puncturing or hole penetration, the thicker elongated needles are used for stripping and releasing tissue adhesion, and the application range of the elongated needles is expanded. But the disadvantage is that the blunt round needle point is very painful and hard to pierce the skin, and the needle insertion experience of the patient is poor. The second defect is that although the Z-shaped needle handle is large in part and convenient to lift and pinch, the Z-shaped needle handle is high in cost and only equivalent to the needle handle in use.

Therefore, on the premise of not damaging nerves and blood vessels easily, having wide adaptive parts and rapidly untying nodules, the development of poking with small pain feeling of needle insertion, convenient operation (such as transverse needling, lifting and twisting) and low cost becomes a bottleneck of the development of acupuncture needles.
