Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, in particular, relate to a fire needle. BACKGROUND

[0002] Fire needle is a traditional Chinese medicine external treatment method, through the red needle is quickly inserted into the body surface to treat diseases. In dermatology, fire needle is mainly used for treating various skin diseases, including acne, flat warts, vitiligo, eczema, neurodermatitis, nodular prurigo and herpes zoster. Fire needle operation is to quickly insert into the human body part when the needle body is red, the process is very fast, and it is difficult to operate, so we summarize the basic essentials of the operation process as "red, accurate, fast" three links. "Red" means that the needle body must be red, "accurate" means that the needle insertion site and the needle insertion depth must be accurate, and "fast" means that the needle body must be fast after being red. The fire needle treatment of psoriasis is a traditional Chinese medicine external treatment method, and the effect is good and the side effect is small. The method is to quickly insert the red needle into the skin to achieve the treatment purpose. The specific operation of fire needle treatment of psoriasis is to take a medium fire needle and burn it on an alcohol lamp, and then point and prick the part with the tinea mass, the depth is about 0.5 cm, and the density is about 0.5 cm. The fire needle for treating psoriasis by conventional needle adopts the mode that a plurality of needle bodies are fixed in the needle handle, in order to facilitate the 0.5 cm gap between the bundled needle bodies, the needle body needs to be twisted manually, the needle body will be deformed again after being heated, and the deformed needle body needs to be corrected again. The reciprocating twisted needle body has reduced overall service life, cannot be replaced by single or multiple needles, and the needle tips of the plurality of needle bodies are difficult to keep in the same plane, which is not conducive to uniform needle treatment.

[0006] As a preferred technical scheme of the utility model, the half circumference side surface close to the knurled nut of the cylinder body is fixed with a row of annular plates.

[0007] As a preferred technical scheme of the utility model, the other half circumference side surface of the cylinder body is provided with a row of ventilation holes; the ventilation holes are composed of four circular ventilation holes arranged in a well shape, and the four circular ventilation holes are all communicated with the inner cavity of the cylinder body.

[0008] As a preferred technical scheme of the utility model, the needle pressing cone core comprises a circular truncated cone matched with the conical surface opening; the small diameter end surface of the circular truncated cone is fixed with a cylindrical rod; the other end of the cylindrical rod is fixed with a threaded stud arranged coaxially; the threaded stud is threadedly connected with the knurled nut; the conical surface of the circular truncated cone is provided with a plurality of U-shaped opening grooves for arranging the needle body.

[0009] As a preferred technical scheme of the utility model, when the needle body main part is completely attached in the U-shaped opening groove, it protrudes out of the conical surface of the circular truncated cone.

[0010] The utility model has the following beneficial effects:

[0011] The utility model adopts the design of needle handle, needle pressing cone core and knurled nut, so that the needle body can be quickly and stably clamped between the needle handle and the needle pressing cone core during assembly, the operation process is simplified, and the working efficiency is improved. Through the annularly and uniformly arranged needle bodies, the distance between the needle tips is fixed at about 0.5 cm, so that the depth and density of the needle application are uniform, and the treatment effect is improved.

[0012] When the needle body needs to be replaced, the knurled nut is loosened, the needle body to be replaced is pulled out, a new needle body is installed, and then the knurled nut is fastened again to complete the replacement operation, which is simple and efficient.

[0013] The utility model fixes a row of annular plates on the half circumference side surface close to the knurled nut of the cylinder body, increases the heat dissipation area, avoids heat concentration, reduces the temperature feeling when holding the needle handle, and reduces the interference during needle application. A row of ventilation holes are arranged on the other half circumference side surface of the cylinder body, forming an annular airflow channel, which has a good heat dissipation effect on the cylindrical rod and the cylinder body, and further reduces the influence of heat on the operator.
