Technical Field

[0001] The invention relates to a multi-purpose injection needle with a new structure, and in particular to a shaping injection needle and a puncture injection needle arranged together, so that skin puncture and shaping can be carried out conveniently and sequentially. Background Art

[0002] Figure 1 An example of a plastic surgery injection needle mainly used in plastic surgery is shown, which is composed of a plastic surgery hub 10 extending in the front-to-back direction and a tubular plastic surgery needle part 20 extending in the front-to-back direction, and the rear end of the plastic surgery needle part 20 is connected and fixed to the plastic surgery hub 10.

[0003] The shaping hub 10 is cylindrical and extends in the front-rear direction with an open rear end. A connecting hole 11 penetrating the inside and outside is formed at the front end, and the rear end is connected and fixed to the neck 2 protruding forward from the front end of the syringe 1 .

[0004] The shaping needle part 20 is formed in a tubular shape made of a thin metal material, the rear end of which is fixed to the connection hole 11 , the front end of which is sealed, and a supply hole 21 is formed on one side of the front end.

[0005] At this time, the front end of the shaping needle part 20 is set to be round.

[0006] Therefore, after a hole is formed on the skin of the patient using a separate puncture needle, the above-mentioned shaping needle part 20 is inserted into the hole formed in the skin, and then the piston set in the syringe 1 is pushed forward, and the filler etc. stored in the syringe 1 is supplied to the skin of the patient through the above-mentioned supply hole 21 to perform a cosmetic surgery.

[0007] However, such a plastic injection needle requires using a separate puncture needle to form a hole in the skin, then removing the puncture needle used to form the hole and inserting the plastic injection needle connected to the syringe 1, which is cumbersome and sometimes the hole formed in the skin cannot be found when the plastic injection needle is inserted.

[0008] In addition, since the process of forming the hole and the process of inserting the plastic injection needle are performed separately, there are problems that the operation time increases and the pain felt by the treated person increases.

[0009] Therefore, a new method that can solve these problems is needed.

[0031] Hereinafter, the present invention will be described in detail based on the accompanying drawings.

[0032] Figures 2 to 7 The multi-purpose injection needle according to the present invention is shown, and the multi-purpose injection needle is composed of a shaping injection needle A, a puncture injection needle B and a rubber ring body 50. The shaping injection needle A is connected to the neck 2 of the syringe 1, and the puncture injection needle B is slidably connected to the outside of the shaping injection needle A along the front-to-back direction. The rubber ring body 50 is connected to the outside of the shaping needle part 20 to support the puncture needle part 40 so that it does not retreat.

[0033] The shaping injection needle A is composed of a shaping hub 10 and a shaping needle part 20. The shaping hub 10 is cylindrical, extends in the front-to-back direction and is open at the rear end, a connecting hole 11 penetrating the inside and outside is formed at the front end, and the rear end is connected to the neck 2. The shaping needle part 20 is tubular, extends in the front-to-back direction and is sealed at the front end, the rear end is connected and fixed to the connecting hole 11 of the shaping hub 10, and a supply hole 21 is formed on one side of the front end.

[0034] Since the configuration of the shaping injection needle A is the same as the existing configuration, further detailed description thereof will be omitted.

[0035] The puncture injection needle B is composed of a puncture hub 30 and a puncture needle portion 40. The puncture hub 30 is cylindrically arranged on the outside of the shaping needle portion 20, extends in the front-to-back direction and has an open rear end, and a connecting hole 31 that passes through the inside and outside is formed at the front end. The puncture needle portion 40 is tubularly arranged on the outside of the shaping needle portion 20, extends in the front-to-back direction and has open front and rear ends, and the rear end is connected to the connecting hole 31 of the puncture hub 30.

[0036] The perforated hub 30 is formed to be connected to the outer side of the shaping hub 10 when sliding backward.

[0037] In addition, the connecting hole 31 of the puncture hub 30 is composed of an inclined portion 31a, an insertion portion 31b and a connecting portion 31c. The inner diameter of the inclined portion 31a narrows toward the front. The insertion portion 31b is formed in front of the inclined portion 31a and has the rubber ring body 50 inserted therein. The connecting portion 31c is formed in front of the insertion portion 31b and extends forward and is connected to the rear end of the puncture needle portion 40.

[0038] The puncture needle part 40 is formed to be shorter in the front-rear direction than the shaping needle part 20, and the front end of the puncture needle part 40 is pointed.

[0039] For example, the shaping needle part 20 is formed to have a length of 30 mm to 70 mm, and the puncture needle part 40 is formed to have a length of 0.2 mm to 35 mm.

[0040] The rubber ring 50 is made of elastic rubber material, and its inner diameter is smaller than the outer diameter of the shaping needle 20 . When the rubber ring 50 clamps the outer side of the shaping needle 20 , it is fixed by its own weight.

[0041] At this time, if Figure 3 As shown, the rear end inner diameter D1 of the inclined portion 31a is larger than the outer diameter D2 of the rubber ring body 50 connected to the shaping needle portion 20, and the front end inner diameter D3 of the inclined portion 31a is smaller than the outer diameter D2 of the rubber ring body 50 connected to the shaping needle portion 20.

[0042] In addition, the inner diameter D4 of the insertion portion 31b is larger than the inner diameter D3 of the front end of the inclined portion 31a.

[0043] In addition, the inner diameter D5 of the connection portion 31 c is smaller than the inner diameter D3 of the front end of the inclined portion 31 a to prevent the rubber ring 50 from being inserted into the connection portion 31 c.

[0044] The method of using the multi-purpose injection needle of the above-mentioned construction will be described below.

[0045] First, if Figure 4 As shown, by connecting the rubber ring 50 to the front end of the shaping needle 20, and connecting the puncture injection needle B to the outside of the shaping needle 20, as shown in FIG. Figure 2 As shown, a multi-use injection needle can be assembled.

[0046] At this time, the puncture injection needle B is arranged so that the front end of the puncture needle part 40 protrudes forward of the shaping needle part 20.

[0047] Then, after the user connects the shaping hub 10 of the shaping needle 20 to the neck of the syringe 1, the user injects the front end of the puncture needle 40 into the skin of the patient, thereby forming a hole in the skin.

[0048] At this time, if Figure 5 As shown, when the puncture needle part 40 is pushed backward, the rubber ring 50 is squeezed between the inclined portion 31a of the puncture hub 30 and the outer peripheral surface of the shaping needle part 20 to prevent the puncture injection needle B from being squeezed backward.

[0049] Therefore, the user can perform the operation of injecting the tip of puncture needle 40 into the skin of the patient with one hand.

[0050] And, if Figure 6As shown, when the puncture hub 30 of the puncture needle portion 40 is held by hand and the syringe 1 is slightly pushed forward, the rubber ring body 50 is compressed by the inclined portion 31a, and the rubber ring body 50 is pushed forward and inserted into the insertion portion 31b, so that the rubber ring body 50 will not be stuck and the shaping injection needle A can move forward freely.

[0051] Therefore, the user can push the syringe 1 forward so that the shaping needle 20 is inserted into the skin of the patient, and Figure 7 As shown, the user slides the puncture injection needle B backwards to connect the puncture hub 30 to the outside of the shaping hub 10 .

[0052] Furthermore, the user pushes the piston of the syringe 1 forward, so that the filler or the like stored in the syringe 1 is supplied to the skin of the patient through the supply hole 21 of the shaping needle 20, thereby performing a cosmetic surgery.

[0053] The multipurpose injection needle as described above has the following advantages. The multipurpose injection needle is composed of a shaping injection needle A, a puncture injection needle B and a rubber ring body 50. The shaping injection needle A is connected to the neck 2 of the syringe 1. The puncture injection needle B is slidably connected to the outside of the shaping injection needle A along the front-back direction. The rubber ring body 50 is connected to the outside of the shaping needle part 20 to support the puncture injection needle B so that it does not retreat. Therefore, the user can use the puncture injection needle B to form a hole on the skin of the patient, and then push the shaping injection needle A forward, which can be inserted into the skin of the patient, and the operation becomes very easy.

[0054] Specifically, the multi-purpose injection needle as described above has the following advantages. The connection hole 31 formed in the puncture hub 30 of the puncture injection needle B is composed of an inclined portion 31a, an insertion portion 31b and a connection portion 31c. The inclined portion 31a is formed so that the inner diameter becomes narrower toward the front. The insertion portion 31b is formed in front of the inclined portion 31a and the rubber ring body 50 is inserted inside. The connection portion 31c is formed in front of the insertion portion 31b and extends forward to connect to the rear end of the puncture needle portion 40. Therefore, if the user pushes the plastic injection needle A forward, the rubber ring body 50 is inserted into the insertion portion 31b, so that the plastic injection needle A can move forward freely, and the puncture needle portion 40 can be inserted into the skin of the person being treated with one hand.
