In the prior art, a wedge-shaped sheet (inserting sheet) is generally inserted into a gap between a needle handle and a needle inlet tube to fix the needle handle and the needle inlet tube, and the inserting sheet is firstly taken out and then a needle is penetrated into an acupoint through a catheter in use, so that the inserting sheet becomes redundant garbage, and the fixing inserting sheet sometimes falls off or loosens in the transportation process, so that the fixing mode has a plurality of defects and shortcomings; in addition, the needle handle and the needle inlet tube are adhered by an ultraviolet light dispensing and curing mode, although the needle handle and the needle inlet tube can be operated by one hand by using the lever principle with the glue fixing point as a fulcrum, the defects are that the procedure is complicated, the connection fastness is uneven, special glue is needed, and the manufacturing cost is increased.
According to the search, as in patent application No. 200480044247.8, publication No. 2007, 9 and 26 discloses a method for fixing an acupuncture needle and a needle insertion tube, in which an acupuncture needle having a metal shank is fixed in a resin needle insertion tube, and the resin at the contact portion between the surface of the shank of the acupuncture needle and the inner surface of the needle insertion tube is melted and fixed by high-frequency induction heating or microwave heating. In this case, the fixing strength between the needle and the tube can be changed by forming the concave-convex portion such as the protruding portion on the metal shank. This application uses high frequency induction heating or microwave heating, and the needle handle must be made of metal, which is not applicable to the current common plastic handles.
