At this time, the needle tube is pressed in the direction of the skin by pressing the needle tube in a state where the plurality of leg pieces provided at the tip of the needle tube are in contact with the skin. The vicinity of the skin of the body insertion portion is pressed with a predetermined pressure by the appropriate elasticity of each leg piece, and each leg piece is bent by its elasticity, so that the skin of the needle insertion portion causes the skin of the needle insertion portion to be compressed. It will be in the state of being pushed open in the outward radial direction with the entrance as the center. Therefore, in this state, after the cut skin (perforation) and the subsequent insertion of the needle body are performed, the outer cylinder is extracted while leaving the needle inserted into the skin.
[0011]
As described above, the needle tip can be stabilized by contacting the plurality of leg pieces with the skin, so that the needle tip can be accurately inserted into the acupoint without supporting the needle body by hand. In addition, the pain of the subject at the time of incision (perforation) can be reduced by compressing and expanding the skin, and the subsequent insertion of the needle can be performed smoothly.
Therefore, since the hands of the practitioner do not directly touch the skin of the practitioner during the treatment, the effect of preventing contamination of the punctured portion can be obtained.
In addition, by setting the elasticity of each of the leg pieces to a predetermined value, it becomes possible to stabilize the compressive strength of the skin within a predetermined range regardless of the experience and skill of the practitioner.
[0012]
In the acupuncture and moxibustion treatment tool according to the second aspect of the present invention, since the needle is configured as described above, the needle tip is housed in the hollow portion of the movable inner cylindrical portion in a state where the needle tip is protruded by a predetermined length. By pushing the knocking part protruding from the end into the outer cylinder with the index finger etc., the movable inner cylinder part containing the needle is pressed against the urging force of the coil spring, and thereby the needle tip is 2 to 2. Not only a cut skin (perforation) that penetrates into a skin as hard as about 3 mm, but also subsequent insertion can be performed continuously.
[0013]
Since the acupuncture and moxibustion treatment device according to the third aspect of the present invention is configured as described above, the interval between the plurality of locking holes formed in the side wall of the outer cylinder in the axial direction is set to a predetermined length. This makes it possible to stabilize the length of insertion at the time of cutting (piercing) and to perform subsequent insertion stepwise.
[0014]
Since the acupuncture and moxibustion treatment tool according to claim 4 of the present invention is configured as described above, it is possible to reuse other members except for the needle by replacing only the leg directly touching the skin with a new one. Thus, the cost can be reduced.
