Description

Micro-needle apparatus for medical treatment

The present invention relates to a medical roughening device, and more particularly, to a medical roughening device having an improved structure so as to lance quickly and smoothly over a large part of the human body.

Medical procedures are performed to circulate the blood of the human body smoothly for good health. In particular, in the case of oriental medical procedures, when blood circulation disorder occurs due to agglomeration or narrowing of blood vessels at certain portions of blood vessels, the blood is forced to flow out of the human body by immersing the blood in a specific region of the human body. Afterwards, the pressure of the specific site to be immersed is increased so that blood flows smoothly to the specific site.

In general, the lanceolating tool is made of a cylindrical member having a long in one direction, and a needle member coupled to the case member, the needle member is elastically moved along the longitudinal direction of the case member by the operator, the case It protrudes from the tip of the member.

Therefore, when the tip of the needle member is brought into contact with the skin of the human body and the needle member protrudes, a hole of a predetermined size is formed by introducing the needle member into the skin of the human body. In this case, blood flows outward through the hole.

On the other hand, when the blood is to be spilled over a wide range of the human body repeatedly by operating the lanceolating tool to form a plurality of holes in the human skin. However, such an immersion tool has a problem that the needle member is repeatedly drawn into the skin of the human body, causing pain to the patient and causing inconvenience in its operation.

Recently, rotary needle tools have been developed to overcome these problems. The rotatable lancet tool comprises a handle member, a plurality of disk-shaped rotation members rotatably coupled to the handle member, and a needle member disposed between the rotation members.

The rotatable lancet tool coaxially arranges the respective rotating members, and arranges a plurality of needle members radially along the circumferential direction between the rotating members, and then couples the rotating members with an adhesive. In this case, the needle member is fixed between the rotating members.

However, the rotary immersion tool as described above has the following problems.

That is, since each of the rotating members are bonded by an adhesive harmful to the human body, there is a problem that may damage the health of the speaker.

In addition, since the separation and recombination process is difficult or impossible at the time of erroneous coupling of each of the rotating members, there is a problem in that the coupling efficiency is demanded and the coupling efficiency is lowered.

In addition, since the needle member is fixed between the respective rotating members by an adhesive, the position alignment state of the needle member can not be easily checked when the respective rotating members are coupled, which lowers product reliability due to defective products. There is also a problem.

Techniques for solving this problem have been filed in Patent Application No. 10-2007-0036647 (filed date; April 13, 2007).

However, this technology is assembled only by the fitting method, and the assembly tolerances of each part make it difficult to recycle the blood between the fitting members when invading the skin of the human body, and it is difficult to recycle the product. There is a disadvantage that it is expensive to discard because of the blood.

Accordingly, the present invention has been made to solve the above disadvantages, and to provide a medical roughening device that can suppress blood from seeping through the parts when immersed in the human skin.

The present invention for solving the above problems is provided with radial ribs which are rotated about a rotation center axis extending in one direction, are radially disposed along the circumferential direction and extend in the rotation center axis direction, and adjacent radial ribs among the radial ribs. A rotation member having a long slit formed in the direction of the center of rotation between the rotational axes; Fitting members to each of the slits, one end of which is fitted along the rotation center axis direction; A needle member penetrating through the fitting member and exposed to the outside, the needle member being rotated together with the rotating member while the fitting member is coupled to the rotating member; A filling hole provided between the adjacent fitting members in a state in which the fitting members are fitted into and coupled to the slits, the filling holes being elongated in the rotation center axis direction; And a filling member filled in the filling hole by an injection molding method.

In the medical roughening device according to the present invention, it is possible to recycle the product by inhibiting blood from seeping between the parts, and the disposal process of the product is reduced when the product is disposed of, thereby reducing the disposal cost of the product.

Hereinafter, a medical roughening apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In this embodiment, the rotating member 1 is rotatably coupled to the handle member 7, and each of the slits 13 includes a first slit part 13a and a second slit part 13b.

One end side of each fitting member 2 is fitted to each of the slits 13 along the rotation center axis direction. By the fitting structure, the assembly efficiency between the rotating member 1 and the plurality of fitting members 2 can be increased.

Particularly, at one end of the fitting member 2, the first inserting portion 21 inserted into the first slit portion 13a and the first slit portion 13a communicate with the second slit portion 13b. The second inserting portion 22 to be inserted into is provided. Here, the first slit portion 13a is formed such that the distance A in the circumferential direction becomes narrower toward the radially inner side of the rotating member 1, and the second slit portion 13b is radially inward. It has the site | part B which becomes increasingly wider in the circumferential direction. By this structure, the fitting member 2 fitted to the slit 13 is prevented from being displaced to the radially outer side of the rotating member 1.

On the other hand, in a state in which the fitting members 2 are coupled to the respective slits 13, a canyon-shaped channel 6 is provided between the other end side of the fitting member 2. The channel 6 is elongated in the direction of the center of rotation axis. As the fitting member 2 is formed to form the channel 6, the contact area with the skin of the human body is reduced, so that the needle member 3 can be precisely penetrated into the human skin.

The rotating member 1 and the fitting member 2 are each made of a synthetic resin material such as ABS (acrylonitrile butadiene styrene copolymer).

A plurality of through holes 23 are formed in each of the fitting members 2 in a line along the direction of the rotation center axis of the rotating member 1. The plurality of needle members 3 are coupled to the fitting members 2 through the through holes 23.

The needle member 3 is exposed to the outside through the fitting member 2, and rotates together with the rotating member 1 in a state where the fitting member 2 is coupled to the rotating member 1.

The needle member 3 is formed by, for example, plating gold on stainless steel. Since the needle member 3 is pressed against the skin of the human body while being rotated together with the rotating member 1, it enables a quick and smooth lance over a large part of the human body.

Next, the filling holes 4 and the filling members 5 will be described with reference to FIGS. 3, 4, and 5.

The filling holes 4 are provided between the adjacent fitting members 2 in a state in which the fitting members 2 are fitted and coupled to the slits 13 and are formed long in the direction of the rotation center axis. . In this embodiment, each of the filling holes 4 is formed at a position far from the first hole 41 in the position close to the slit 13 and in the circumferential direction than the first hole 41. The second hole 42 is formed.

Each of the filling members 5 includes a first filling portion 51 filled in the first hole 41 and a second filling portion 52 filled in the second hole 42. In this embodiment, the filling member 5 is made of a synthetic resin material.

The filling member 5 is filled in the filling hole 4 by an injection molding method, thereby filling gaps due to component tolerances between the fitting member 2 and the rotating member 1. For example, as shown in FIG. 4, the first hole is inserted as shown in FIG. 4 by inserting an assembly in which the rotating member 1 and the fitting member 2 are combined into a mold and injecting a melt into the mold. The first filling portion 51 is filled in the 41 and the second filling portion 52 is filled in the second hole 42. According to this molding process, the blood generated by the needle member 3 penetrates into the skin of the human body to be prevented from seeping through the gap, the product can be recycled or introduced into the gap when discarded The process for removing blood has the advantage of reducing the cost of disposal.

On the other hand, the filling member 5 is provided with the third filling portion (53). Although the third filling part 53 is illustrated separately from FIGS. 4 and 5 for convenience of description, the melt flowing into the first hole 41 and the second hole 42 of FIG. 4 is rotated by the rotating member 1. It is formed by filling in the both ends of the axial direction of (). In this case, the third filling portion 53 is filled on both end sides of the rotating member 1, so that the rotating member 1 is positioned in the fitting direction (rotation center axis direction) of the fitting member 2. It is possible to prevent the departure.

And the annular groove part 15 is provided in the both ends of the axial direction of the said rotating member 1. As shown in FIG. As the melt flows into the annular groove 15, the coupling between the rotating member 1 and the third filling portion 53 may be more firmly performed.

Hereinafter, the operation of the medical rough device according to an embodiment of the present invention will be described in detail.
