Needle insertion device for floating needle

Abstract

The disclosure relates to a needle insertion device for floating needles, which includes a base, the surface of the base has a through groove for guiding the floating needle, an ejector is installed at one end of the base, and a detachable clamping plate is attached to the base. For the through groove and can slide along the direction of the through groove, the side of the pressure plate close to the through groove is fixed with a baffle, and the end of the baffle close to the through groove is provided with an opening, and the opening can be engaged with the outside of the floating needle, so that the pressure plate can drive The floating needle moves towards the catapult. The present disclosure is convenient for realizing the position limitation of the floating needle during ejection, avoiding the dislocation of the floating needle during ejection, and simultaneously reducing the difficulty of placing the floating needle in the ejector.

Description

technical field [0001] The disclosure belongs to the technical field of medical equipment, and in particular relates to a needle insertion device for floating needles. Background technique [0002] Floating needle is the abbreviation of floating needle therapy, and it is also the abbreviation of its special tool for one-time use of floating needle. Floating needle therapy is improved from wrist-ankle acupuncture. It is an acupuncture therapy that uses one-time use of floating needles to sweep away the superficial fascia layer (mainly subcutaneous loose connective tissue) in non-painful areas. It has almost painless, Quick results, wide indications and other characteristics. [0003] Some commonly used floating needle structures are disclosed in existing patent documents CN204709389U and CN204932248U5 respectively. During the use of the floating needle, the needle tip needs to be at a set angle with the skin, quickly inserted into the superficial fascia layer to set the dep...

AI Technical Summary

Problems solved by technology

[0006] (1) It is necessary to push the handle of the floating needle so that the floating needle is pressed towards the elastic device, and the elastic device continues to have elastic potential energy, but the contactable area of ​​the handle of the floating needle is small, when the elastic modulus of the spring in the elastic device When it is larger, it is more difficult for the elastic device to accumulate elastic potential energy by using the floating needle handle

[0007] In the treatment of special positions such as the neck with floating needles, the position of the floating needle injector in space is uncertain, the floating needles are easy to fall off from the needle injector, and the position and posture of the floating needles after ejection are also uncontrollable, which is prone to Failed to insert the needle and cause contamination of the needle body
