BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) FIGS. 1 (a) and 1 (b) are side views showing a configuration of a beating needle according to a first embodiment of the present invention. As shown in FIGS. 1A and 1B, the beating needle according to the present embodiment includes a first needle body 10 and a second needle body 20.

The first needle body 10 is formed of a thin tube 11 (outer diameter D is about 2 mm) made of an elastic metal material having corrosion resistance, for example, stainless steel. The distal end (the lower end in the figure) of the thin tube 11 is a pointed end 12 (length L is about 2 mm), and the base end (the upper end in the figure) is an opening 13.

The second needle body 20 is mainly formed of an elastic metal material also having corrosion resistance, for example, a filament 21 made of stainless steel (outer diameter d is about 1.5 mm).
Since the first needle body 10 has sufficient viscoelasticity as described later, the second needle body 20 does not necessarily need to be formed of an elastic metal material.

The distal end of the filament 21 is provided so as to be inserted into the hollow hollow portion 14 of the first needle body 10 through the opening 13. The distal end of the filament 21 to be inserted into the hollow portion 14 of the first needle body 10 is
The tip 22 has a shape substantially similar to the shape of the one tip 12, that is, a conical shape. It is also possible to cut off the foremost end 23 of the pointed end portion 22 in consideration of the operability at the time of insertion so as to form a truncated cone. A striking head 24 is provided at the base end (the upper end in the figure) of the filament 21.

In the beating needle shown in FIG. 1A, the length of the filament 21 is formed to be slightly longer than the length of the thin tube 11. The neck portion 20 'is exposed over the length G. The neck portion 20 ′ has effects such as improving operability when performing the insertion / removal operation of the filament 21.
It is not always necessary to perform the above, and both may be set to have substantially the same length so that the filament 21 is almost completely accommodated in the thin tube 11.

In the present embodiment, the first needle 10
Is formed of an elastic metal material having corrosion resistance, for example, a thin tube 11 made of stainless steel, and has a so-called pipe shape. For this reason, the viscoelasticity of the needle is remarkably improved as compared with a conventional one formed by a simple linear body. As a result, even if a large bending stress or the like acts on the beating needle, there is no possibility that breakage or the like is easily generated, and the reliability is extremely high. Further, in the present embodiment, the filament 21 of the second needle body 20 can be appropriately inserted into the thin tube 11 of the first needle body 10 for use. Therefore, for example, by heating the filament 21 to a predetermined temperature and inserting it into the inside of the thin tube 11, it is possible to keep the pointed end 12 of the thin tube 11 at a required temperature of 50 ° C. or less. Thus, the stimulation by the needle can be applied while the affected area is heated to an appropriate temperature. As a result, the effect of "moxibustion" is added to the effect of "needle", and a synergistic effect of both can be expected. In addition, it is also possible to attach a magnet or the like to the distal end portion of the striated line 21 so that the magnetic field lines act on the affected part.

(Second Embodiment) FIG. 1C is a side view showing a configuration of a beating needle according to a second embodiment of the present invention. As shown in FIG. 1C, the tapping needle of the present embodiment uses only a thin tube 11 made of a corrosion-resistant elastic metal material, for example, stainless steel, as a needle body. The tip of the thin tube 11 is a pointed end 12 as in the first embodiment. A tapping head 30 is attached to the opening 13 at the base end (upper end in the figure) of the thin tube 11.
The hitting head 30 has an insertion pin 31, which is integrated with the thin tube 11 by inserting the insertion pin 31 into the opening 13.

In this embodiment, the first needle 10
Is formed of an elastic metal material having corrosion resistance, for example, a thin tube 11 made of stainless steel, and has a so-called pipe shape. Therefore, it is formed of a simple linear body as in the case of the first embodiment. The viscoelasticity of the needle body is remarkably improved as compared with the related art. As a result, even if a large bending stress or the like acts on the beating needle, there is no possibility that breakage or the like is easily generated, and the reliability is extremely high.

By filling an appropriate heat storage medium into the thin tube 11 of the first needle body 10 and using the heat storage medium in a state where heat is stored, a thermal effect on the affected part at the pointed end 12 is obtained. May be provided. This makes it possible to stably apply the above-mentioned heating effect to the affected part over a relatively long time.

(Characteristic points in the embodiment) The characteristic points of the tapping needle shown in the embodiment (including the modification) are summarized as follows.

The viscoelasticity of the body is dramatically improved. As a result, even if a large bending stress or the like is applied to the beating needle, there is no possibility that breakage or the like is easily caused, and the reliability is extremely high. [2] The tapping needle shown in the embodiment is made of a corrosive elastic metal material, and has a thin tube 11 having a tip 12 at the tip and an opening 13 at the base. A first needle body formed of a metal material having corrosion resistance, and a distal end portion provided to be insertable into the hollow portion of the first needle body from the opening; A second needle body 20 provided with a beating head 24 in the portion;
It is characterized by having.

In the above-mentioned beating needle, the same effect as [1] is obtained, and the second needle 20 made of the filament 21 is inserted into the thin tube 11 of the first needle 10. Therefore, for example, the filament 21 is heated to a predetermined temperature to
1 inserts into the tip 12 of the capillary 11
Can be set to a required temperature of 50 ° C. or less. Thus, the stimulation by the needle can be applied while the affected area is heated to an appropriate temperature. As a result, the effect of "moxibustion" is added to the effect of "needle", and a synergistic effect of both can be expected. [3] The tapping needle shown in the embodiment is the tapping needle according to the above [1], and the heat storage medium is filled in the thin tube 11 of the first needle body 10. When used in a state in which heat is stored in the head, a heat effect can be imparted to the affected part at the pointed end 12. The above-mentioned beating needle has the same operation and effect as [1] and can stably impart the above-mentioned heating effect to the affected part over a relatively long time.
