Background
The floating needle is short for floating needle therapy, and is also short for disposable floating needle of special tools. The floating needle therapy is improved from a wrist ankle needle, is an acupuncture therapy of a sweeping and scattering method by using a disposable floating needle on a superficial fascia layer (mainly subcutaneous loose connective tissue) in a non-pain area, and has the characteristics of little pain, quick response, wide adaptation diseases and the like.
For example, conventional float needle structures are disclosed in CN204709389U and CN204932248U5, respectively. In the use of float needle, need the needle point to be at the settlement contained angle with skin, insert the setting depth of shallow rete fast, then the operator pushes the holistic subcutaneous tissue of needle body into. In this process, in order to increase the speed of inserting the needle tip and reduce the discomfort of the patient, a floating needle inserting device is generally adopted.
The inventor knows about a floating needle inserting device, which comprises a base, an elastic device is arranged at the rear part of the upper surface of the base, and a through groove is formed at the front part of the upper surface of the base through a positioning part, so that a floating needle is arranged in the through groove and can slide along the through groove; when the floating needle is used, after the floating needle is arranged in the through groove, the through groove needs to be forcibly extruded towards the elastic device, so that the elastic device accumulates elastic potential energy and fixes the elastic potential energy; then through the button switch, the elastic device can instantly release energy to eject the floating needle along the through groove for setting the length, thereby achieving the purpose of needle insertion.
The inventor believes that the floating needle inserter has the following disadvantages:
(1) the handle of the floating needle needs to be pushed to extrude the floating needle towards the elastic device and enable the elastic device to continue elastic potential energy, but the contactable area of the handle of the floating needle is small, and when the elastic modulus of the spring in the elastic device is large, the difficulty of accumulating the elastic potential energy by the elastic device by utilizing the handle of the floating needle is large.
When the floating needle is used for treating special positions such as the neck, the position of the floating needle inserting device in the space is uncertain, the floating needle is easy to fall off from the needle inserting device, the position posture of the ejected floating needle is also uncontrollable, the situation of needle inserting failure is easy to generate, and the pollution of a needle body is caused.
