Development of floating needle therapy

When we used floating needle therapy, we used the traditional acupuncture needle-filiform needle as a tool of floating needle therapy, which was effective for treating diseases with small parts and less pain, but the following factors prompted us to make up our mind to change needles:

(1) When the lesion is large or deep, the effect of floating needle therapy with filiform needle as a tool is not obvious, and many filiform needles are often needed or even ineffective.

(2) Because floating needle therapy needs to keep the needle for a long time, the filiform needle made of metal left in the body often causes pain due to sports and other factors, or pierces blood vessels and other tissues.

(3) Metal needle indwelling in the body will cause a strong psychological burden to patients.

(4) According to our observation, the curative effect of floating needle therapy is closely related to the thickness of needle.

(5) When using the filiform needle as a floating needle treatment instrument, many patients are worried that leaving the metal needle in the body will cause consequences that they can't handle at home, so they would rather waste time waiting for the doctor to get the needle and then get off work. This not only consumes doctors' time, but also is not conducive to the use of department space.

Due to the above situation, we invented the floating needle (floating needle for short), which is now a soft trocar. Although it seems that the floating needle is nothing remarkable now, at that time, we spent a lot of time and energy and took several steps to get this little invention:

(1) First of all, we think of using physical methods to achieve our goals.

(2) Chemical methods can also be considered.

(3) Inject a certain amount of liquid (such as glucose injection) into the subcutaneous loose connective tissue.

Finally, we thought of a compound method: the main structure is a soft sleeve and a stainless steel needle core sheathed inside. The former has good flexibility, while the latter has sufficient rigidity and hardness. In 2002, it won the national invention patent (see photo).
