Hereinafter, the present invention will be described in detail with reference to the preferred embodiments of the present invention with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

2 to 4 are block diagrams showing a configuration of a medical lancing needle according to an embodiment of the present invention.

2 to 4, a medical lancing needle 200 according to an embodiment of the present invention includes a needle tube 210, a wing 220, a needle 230, 240, 250 and 255, a fixing portion 260, A cover 270, and the like.

The needle tube 210 is configured in a hollow form and the treatment thread is disposed so as to penetrate therethrough so that the treatment thread can be inserted into the skin as the tip of the needle tube 210 penetrates into the skin.

That is, the medical lancing needle 200 according to the exemplary embodiment of the present invention is particularly applicable to facial lifting procedures for removing wrinkles and the like. Accordingly, in the specification and drawings of the present invention, Only the case where the procedure room T is inserted will be described.

The wing 220 functions as a handle for improving convenience of operation and may have any conventional configuration. In the embodiment of the present invention, a comb tooth is formed on the blade 220 for slip prevention or the like, but the present invention is not necessarily limited thereto.

The hoppers 230, 240, 250 and 255 are formed in a hollow form and accommodate a middle lower end portion of the tubular tube 210 therein. One end of the tubular tube 230 is tightly coupled to the tubular tube 210, So that the fixing portion 260 is fixedly supported on the opening region 235.

In other words, the pouring tube 210 is disposed to penetrate the puddles 230, 240 and 250, one end of the puddle is fixedly supporting the puddle tube 210, and the other end thereof is fixedly supported by the fixing part 260.

In this case, the sinkers 230, 240 and 250 may have a stepped portion having a stepped portion B on the outer surface. In this case, the cover 270 may have an inner diameter and an outer diameter corresponding to the stepped portion B of the stepped portion. And may be configured to be fixedly supported through fitting engagement with the sinker 230.

That is, the outer diameter of the lid 270 is set to have the same outer diameter as that of the settler 240 having the maximum outer diameter, and the inner diameter of the lid 270 is set to be the same as that of the settler 230, The lid 270 can be fitted to the sink 230 and the outer surface of the lid 270 can be flush with the outer surface of the sinker 240 .

The fixing portion 260 is inserted and fixed in the other end opening region 235 of the needle 230 as described above and is fixed to the treatment chamber T passing through the needle tube 210, . The diameter of the opening A of the sinker 230 and the diameter of the hole 260 of the fixing part 260 may be equal to each other. It is preferable that the fixing portion 260 can be stably accommodated in the opening region of the droplet 230 by properly matching the diameter A of the region.

With the provision of the fixing portion 260 as described above, it is possible to quickly and easily fix the treatment chamber T without the need of separately knotting the treatment chamber T, thereby improving the convenience of the procedure and further improving the safety of the procedure And the like can be provided.

Here, the fixing portion 260 may be formed of an object having an elasticity of a proper level or more so that the fixing portion 260 can be easily inserted into the opening region 235, and it is preferable that the fixing portion 260 is formed of a medical cotton, have. However, it should be understood that the present invention is not necessarily limited thereto.

The lid 270 is configured to have an inner diameter and an outer diameter corresponding to the deposits 230 and 240, so that the lid 270 can be easily and stably fixed.

Accordingly, it is possible to secure the safety of the surrounding persons from the capillary tube 210 by using the stably fixed cap 270, and to protect the capillary tube 210 from the external pressure or the like. It is preferable that the lid 270 is formed so that its end is equal to or longer than the end of the capillary tube 210 as shown in the drawings.

The medical punctum needle 200 according to the embodiment of the present invention may be detachably installed between the needle tube 210 and the needle holders 230, 240, 250 and 255, And the remaining components can be configured to be recyclable.

In other words, it is possible to recycle the portion other than the capillary tube 210 in which the capillary is directly inserted into the human body in the single-use capillary needle, thereby reducing the manufacturing cost of the capillary needle 200 and protecting the environment .

It will be appreciated by those skilled in the art that any conventional detachable coupling method (screw coupling, rivet coupling, etc.) may be applied between the tubing 210 and the sinkers 230, 240, 250,

FIG. 5 is an exemplary view for explaining the internal configuration of the medical lancing needle according to the embodiment of the present invention. The coupling method between the needle tube 210 and the sinkers 230, 240, 250, .

5 (a) and 5 (b), it can be seen that one end of the sinker 250 is composed of at least two structures 250 and 255. In other words, An outer sinker 250 spaced apart from the inner sinker 255 and surrounding and accommodating the inner sinker 255 and an outer sinker 250 separated from the inner sinker 255 and the outer sinker 250 And an elastic body 280 connecting between the elastic body 280 and the like.

That is, the inner needle 255 may be formed to have an inner diameter large enough to engage with the outer diameter of the cap 210, and may have an inner diameter that is the same as the outer diameter of the cap 210, (E.g., synthetic resins, etc.).

Accordingly, it is possible to stably fix the capillary tube 210 through a process of inserting the capillary tube 210 into the inner capillary 255 in such a manner that the capillary tube 210 can be stably inserted into the capillary tube 255. The inner capillary 255 can be elastically deformed by a small amount of elastic force The inner diameter is slightly enlarged by the inner diameter of the inner tube 210, so that the inner tube 210 can be received.

A case in which the inner sinker 255 in which the sinker pipe 210 is accommodated is shown in (b) and a case in which the inner sinker 257 is provided with a clearance portion for facilitating the inner diameter expansion is shown in (b) Respectively.

At this time, in the case of the inner sinker 257 having the clearance portion as shown in (c), the body portion can be formed using various methods such as having a dual structure of an inner wall having a slight elastic force and a solid outer wall . However, the present invention is not necessarily limited thereto.

In the embodiment of the present invention, when the capillary tube 210 is accommodated in or separated from the inner capillary 255 or 257, the inner diameter of the inner capillary 255 or 257 corresponds to the degree of expansion or contraction of the inner capillary 255 or 257, A plurality of elastic members 280 are provided for supporting the inner sinkers 255 and 257 with the outer sinkers 250 in a stable manner at all times.

It should be noted that any elastic body including a conventional spring may be used as the elastic body 280, and it is preferable that the number of the elastic body 280 is two or more.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art. The embodiments described above are therefore to be considered in all respects as illustrative and not restrictive.
