Description

Multi Injection Needle for Controlling Injection Depth

The present invention relates to a multi-scan needle, and more particularly to a multi-scan needle that can adjust the depth of the needle injected into the skin.

Recently, a method of treating the skin in various forms has been introduced to prevent aging of the skin. The most typical of these is the most widely used form of massage using beneficial substances containing nutrients to the skin.

However, the method of treating the skin in the form of massage is to supply nutrients to the epidermal layer of the skin to make the epidermal layer smooth, but it does not last a long time, and the inconvenience of requiring periodic management as well as economic cost is a problem. Had

As another method, a manual method of injecting cosmetic liquid into the skin using a syringe or the like is also widely used. In other words, a medical treatment called meso therapy has been introduced in the fields of partial obesity, skin beauty, and cosmetic surgery. Mesotherapy is a procedure in which a variety of drug ingredients are appropriately mixed in a site where a therapeutic effect is desired by using a fine needle, and injected directly into the meso tendon, that is, a drug is injected directly into the skin layer.

In the direct injection of drugs into the skin layer, the depth of the needle injected is very important. The thickness of the skin layer may vary according to various conditions, such as Asian and Western people or those with thick subcutaneous fat layers, and the depth of injection of the needle may vary according to the skill of the operator. After injecting hundreds of needles, it is very difficult to inject drugs with uniform depth to each other. Injecting the drug at a uniform depth has a profound effect on the effect of the drug and the recovery time after the procedure.

Referring to the drawings, a multi-scan needle 100 of one preferred embodiment of the present invention is nine needles 110, a multi-scan needle hub 120, a multi-scan needle cap 130, a hollow cylindrical rotating body 140, A protective cap 150 is included.

Nine needles 110 is one needle is placed in the center and eight needles are arranged around it. In the present invention, the number and arrangement of the needles are not limited to the embodiments, and various modifications are possible. For example, various arrangements of a plurality of needles, such as arrangement of 2 × 2, 3 × 3, ..., n × n, arrangement in a row, arrangement in two rows, and the like are possible. In addition, the thickness of the needle may have various thicknesses, for example, within the range of 0.1 mm to 3 mm.

The multi-scan needle hub 120 is composed of a cylindrical front end portion 122 and the pipe-shaped rear end portion (124). The cylindrical tip portion 122 is formed with four guide grooves 122b at equal intervals in a direction perpendicular to the outer circumferential surface 122a. Here, the vertical is the same direction as the direction parallel to the longitudinal direction of the needles (110). Each guide groove 122b is formed by a predetermined length from the outer peripheral surface leading edge. A locking groove 122c is formed in the outer circumferential surface between the trailing edge of the cylindrical tip portion 122 and the rear end of the guide groove 122b. The locking groove 122c extends in the circumferential direction to form an annular shape. An inner space portion 122d is formed inside the cylindrical tip portion 122, and ends of the hollow needles 110 are disposed in the inner space portion 122d to communicate with the inner hollow portions of the needles 110. The pipe-shaped rear end portion 124 has a flange 124a formed at its end and an insertion groove 124b into which the front end of the syringe cylinder is inserted. A connecting passage 126 is formed which communicates from the insertion groove 124b of the pipe-shaped rear end portion 124 to the cylindrical front end portion 122 and the inner space portion 122d. Therefore, the injection liquid is provided at the tip of the needle through the connecting passage 126, the internal space 122d and the hollow of the needles 110.

The multi-scan needle cap 130 has a front 132, outer circumferential surface 134, the rear ruptured cylinder structure having an inner circumferential surface 136. The front surface 132 is formed with through holes 132a through which nine needles 110 pass. The outer diameter formed by the outer circumferential surface 134 is smaller than the inner diameter of the hollow cylindrical rotor 140 and the inner diameter formed by the inner circumferential surface 136 has a size larger than the outer diameter of the cylindrical tip portion 122. Male threads 134a are formed at the rear of the outer circumferential surface 134, and four guide rails 136a extending in the vertical direction are formed at the inner circumferential surface 136 at equal intervals. The guide rails 136a are inserted into four guide grooves 122b formed on the outer circumferential surface of the cylindrical tip portion 122 and slidably coupled in the vertical direction.

The hollow cylindrical rotor 140 has an outer circumferential surface 142 and an inner circumferential surface 144. The inner diameter formed by the inner circumferential surface 144 is larger than the outer diameter of the multi-scan needle cap 130. A female thread 144a is formed on the inner circumferential surface 144, and the female thread 144a is engaged with the male thread 134a and screwed thereto. On the rear inner circumferential surface 144 on which the female thread 144a is formed, an annular locking protrusion 144b or a locking frame is formed. The locking protrusion 144b is inserted into the locking groove 122c and serves to allow the hollow cylindrical rotor 140 to rotate only in place without moving in the vertical direction. Therefore, when the hollow cylindrical rotor 140 is rotated in place, the male thread 134a engaged with the female thread 144a receives a force in the vertical direction, so that the multi-needle cap 130 is in the subic direction, that is, in the longitudinal direction of the needle. Is moved. Therefore, the length of the needle 110 exposed out of the front surface 132 through the through hole 132a of the multi-scan needle cap 130 is variable. That is, the operator can set the depth of the needle injected into the skin by turning the hollow cylindrical rotating body 140. That is, FIG. 2 shows a needle length setting state of deep injection depth, and FIG. 3 shows a needle length setting state of shallow injection depth.

The protective cap 150 is detachably mounted to the tip of the outer circumferential surface 134 of the multi-scan needle cap 130 to protect the exposed needle portion.

As mentioned above, the multi-scan needle according to the embodiment of the present invention has been described with reference to the drawings, but the drawings and the description thereof are exemplary and have ordinary skill in the art without departing from the technical spirit of the present invention. Modifications and changes may be made by the user. For example, in the above-described embodiment, the structure of the guide groove and the guide rail has been described, but a plurality of needles and through holes may be substituted instead of these structures. Therefore, the technical idea of the present invention should not be limited to the embodiments of the present invention.
