Description
Technical Field
The utility model belongs to the field of traditional Chinese medicine acupuncture medical instrument, specifically speaking is a sterile segmentation sleeve pipe mango needle.
Background
The elongated needle is a traditional Chinese medicine acupuncture and moxibustion instrument and is developed from a long needle which is one of ancient nine needles. It is made of stainless steel wire, so that its needle body is slender like wheat and mango, so that it is called Miscanthus needle. As early as 2000 years ago, the monograph of traditional Chinese medicine acupuncture & moxibustion in Ling Shu, nine needles twelve Yuan (Chinese medicine and acupuncture and moxibustion) has been recorded: 'eight long needles, seven inches long, … … long needles are sharp and thin, long arthralgia can be got, … …' long needles are different from general acupuncture, long needles are longer, deep needles are inserted, especially suitable for puncturing, can be directed and deep penetrated, achieve one needle with multiple points, avoid pain caused by repeated needle insertion, enlarge the acupuncture induction surface, penetrate through multiple meridians, and achieve the functions of dredging meridians, regulating qi and blood, calming the nerves, relieving pain, dissipating blood stasis and breaking blood. Has special treatment effect on deep disease positions which are not suitable for nearby acupuncture, and can make up for the deficiency of short needles.
Currently, acupuncture clinical operation is generally aseptic, the needle needs to be kept sterile before the needle pierces the skin, the requirement is more strict abroad, and in the operation process, the hands of a practitioner cannot contact the needle body, so that the needle is prevented from being polluted. However, the long needle has a long specification, and the traditional needle clamping method is required, and the needle clamping method requires the operator to pinch the lower segment of the needle body with one hand, so that the needle tool is inevitably polluted, the wide application of the long needle is limited, and the popularization and the internationalization of acupuncture are not facilitated.
At present, in order to solve the pollution problem in the acupuncture operation process, the trocar technology is generally adopted, namely an acupuncture needle is arranged in a plastic sleeve, a part of the needle tail protrudes out of the sleeve, an inserting piece is clamped between a needle handle and the sleeve, the inserting piece is pulled out when the acupuncture needle is used, the needle is flicked into an acupuncture point, and then the sleeve is taken out. The technology is applied to short needles with good effect and can achieve the effect of avoiding pollution. However, because the elongated needle is long, if the traditional trocar technology is adopted, after the needle is flicked into an acupuncture point and the cannula is taken out, the elongated needle is deviated to one side under the action of gravity due to the long needle body of the elongated needle, and the elongated needle contacts the skin of a patient, so that a needle tool is polluted.
Chinese patent documents: CN203089865U discloses a combined sleeve for sterile acupuncture needle, which comprises a hollow first sleeve and a hollow second sleeve, wherein the opening area of the end of the first sleeve is larger than the opening area of any end of the second sleeve, and the opening area of the other end of the first sleeve is smaller than the opening area of the end of the first sleeve. Because first sleeve pipe is little with skin area of contact for acupuncture needle is adjustable different angle when its inside, with the acupuncture needle insertion mode of adaptation flat thorn or oblique thorn, first sleeve pipe is connected the back with the second sleeve pipe simultaneously, still can avoid giving needle the person's finger of executing needle to pollute the needle body as supplementary the instrument of holding with, and continue to keep first sleeve pipe after the needle insertion is accomplished and avoid pricking the skin at position to receive the infection of pathogenic bacterium as isolation protection device, simultaneously the utility model provides a combination sleeve pipe for aseptic acupuncture needle, simple structure is suitable for and uses in all kinds of acupuncture treatments, and the range of application is wide, and is suitable for industrial production, easily promotes. However, for the elongated needles, the length is long, and the lengths of different elongated needles are different, and the needles are required to be sequentially arranged, the needles of the elongated needles are thin, if the length of the sections of the sleeve is too long, each section is taken down, the exposed sections are lack of the support of the sleeve, the needles are easy to be arranged unstably, pain of a patient can be caused, the curative effect is affected, if the sections are too short, the required number of sections is large, the operation is troublesome, and the elongated needles are not suitable for the elongated needles with the long length; and the sleeve is separated from the needle, the needle body is contaminated in the process of inserting the needle into the sleeve. In summary, there is a need for a sterile segmented sleeve elongated needle which has a segmented telescopic function, can be fixed, sterilized and packaged with the elongated needle, and can perform acupuncture and moxibustion in a sterile manner in the whole process.
