At the beginning, when we used floating needle therapy, we used traditional acupuncture needles - filiform needles. Filiform needles are used as tools for floating needle therapy, which can achieve quick results when treating diseases with smaller parts and less pain. , the curative effect is relatively accurate, but the following factors prompted us to make the decision to change the needles:
(1) When the lesion is large or deep, the effect of floating needle therapy using filiform needles as tools is not obvious. Often multiple filiform needles are needed, and even multiple needles are ineffective.
(2) Because floating needle therapy requires needle retention for a long time, when filiform needles made of metal are left in the body, they often cause pain due to movement and other factors, or puncture blood vessels and other tissues.
(3) Leaving metal needles in the body will cause a huge psychological burden on the patient.
(4) According to our observation, the efficacy of floating needle therapy is closely related to the thickness of the needle.
(5) When using filiform needles as floating needle therapy devices, many patients are worried that leaving metal needles in the body will cause consequences that they cannot handle at home, so they would rather waste time and wait for the doctor to get them before leaving get off work. Needle. This not only consumes the doctor's time, but also is not conducive to the use of department space.
Due to the above-mentioned various situations, we invented the floating needle needle (referred to as floating needle), which is now the soft trocar needle. Although there is nothing magical about floating needles now, it took us a lot of time and energy at the time, and it took several steps to come up with this little invention:
(1) First of all, we thought Use physical methods to achieve your 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 composite method: the main structure is a soft cannula and a The stainless steel needle core set in it has good softness while the latter has sufficient rigidity and hardness. Obtained the national invention patent in 2002 (see picture).
