[0040] Hereinafter, the most preferred embodiment of the present invention will be described in detail to enable a person having ordinary skill in the art to easily carry out the present invention.
[0041] The numbers cited in the examples below are not limited to the referenced objects and can be applied to all examples. Objects that achieve the same purpose and effect as the structures presented in the examples are equivalent replacement objects. The superordinate concepts presented in the examples include subordinate concepts not described.
[0042] (Example 1-1) The present invention relates to a handpiece for drug injection, comprising: a multi-needle (100) in which a drug syringe (10) containing a drug is coupled, and which penetrates the drug when the needle (20) is inserted into the skin to perform a procedure; a main body (500) which fixes the multi-needle (100) and the drug syringe (10) and controls the amount of drug injected and the temperature of the multi-needle (100); a drug injection device (600) formed inside the main body (500) and which controls the amount of drug injected by controlling the pressure of the drug syringe (10); and a temperature control device (700) formed at a lower portion of the drug injection device (600) and connected to the multi-needle (100) to control the temperature.
[0043] (Example 1-2) The drug injection handpiece of the present invention includes, in Example 1-1, the drug syringe (10) formed as a syringe in which a drug is stored.
[0044] (Example 1-3) The drug injection handpiece of the present invention includes, in Example 1-2, the needle (20) protruding outward from the multi-needle (100) and inserted into the skin.
[0045] (Example 1-4) The drug injection handpiece of the present invention includes, in Example 1-3, the multi-needle (100) connected to the main body (500) and having its temperature controlled.
[0046] (Example 1-5) The drug injection handpiece of the present invention includes, in Example 1-4, the temperature control device (700) that supplies cold air or heat.
[0047] The present invention relates to a drug injection handpiece, and more specifically, to a drug injection handpiece for injecting drugs into the skin. This drug injection handpiece comprises a drug syringe (10) containing a drug, and a plurality of needles (20) protruding from the syringe to inject a predetermined amount of the drug into the skin.
[0048] In general, medical devices using multi-needles (20) include water light syringes that inject specific drugs into the skin and high-frequency multi-needle (20) treatment devices that apply high-frequency waves into the skin. At this time, the water light syringe is a medical device that uses multi-needles (20) consisting of 3*3 or 4*4 needles to inject specific drugs into the subcutaneous layer at a certain depth, and injects the drugs subcutaneously through the central cavity of each needle. In addition, as a method of inserting multiple needles into the skin by passing through the resistance of the skin, an air suction device is installed at the tip of the multi-needle (20) to pull the skin toward the needles so that the skin is inserted into the needles.
[0049] In addition, the high-frequency multi-needle (20) treatment device uses a multi-needle (20) connected to a high-frequency generator to generate multiple microscopic tissue coagulations at a certain depth under the skin. At this time, when high-frequency is applied to the needles inserted into the skin, Joule heating is generated in the subcutaneous tissue, and the microscopic tissue coagulation (coagulation) caused by this heat causes tissue damage (electrothermal damage) and the body's natural healing process (wound healing process) occurs. This increases collagen and elastin in the skin and has the effect of reducing minor wounds and wrinkles, making the skin smoother and looking younger. In order to artificially generate multiple microscopic tissue damages in this way, the high-frequency needle treatment device (Fractional Radio Frequency Microneedling) has multiple needles attached to a single surface, 7*7 or 9*9. It is a medical device that injects high-frequency waves into the skin through each needle to raise the temperature around the needle to 42℃ or higher, thereby generating small tissue coagulations in the subcutaneous layer around the needles. The multi-needle (20) used in such water light syringes and high-frequency multi-needle (20) treatment devices causes pain when inserted into the skin or when injecting medication, which can cause discomfort to the patient. In addition, temperature control of the treatment area is required to improve the effectiveness of high-frequency multi-needle (20) or drug-injecting multi-needle (20) treatments.
[0050] On the other hand, referring to FIG. 1, the drug injection handpiece of the present invention is formed by combining a drug syringe (10) formed as a syringe in which a drug is stored, a multi-needle (100) that injects the drug as the needle (20) is inserted into the skin to perform the procedure, a main body (500) that fixes the multi-needle (100) and the drug syringe (10), and controls the amount of drug injected and the temperature of the multi-needle (100), a drug injection device (600) formed inside the main body (500) and that controls the amount of drug injected by controlling the pressure of the drug syringe (10), and a temperature control device (700) formed at the bottom of the drug injection device (600) and connected to the multi-needle (100) to control the temperature. At this time, the multi-needle (100) is inserted into the skin so as to protrude outward, and the surface of the skin is formed of metal so that the temperature can be controlled to reduce pain and increase the hemostatic effect. And the main body (500) can guide the injection of a precise amount of drug at an accurate location by fixing the multi-needle (100) and the drug syringe (10), and can inject a precise amount of drug while reducing pain at the same time by the drug injection device (600) and the temperature control device (700).
[0051] Therefore, the drug injection handpiece of the present invention has the characteristic of being able to supply a fixed amount of drug while simultaneously controlling the surface temperature in contact with the skin.

[0059] The present invention relates to an injection unit (110), and specifically, the injection unit (110) is configured to deliver a drug to a needle (20) by coupling a drug syringe (10) to the rear surface. Referring to FIGS. 4 and 5, the injection unit (110) is configured to deliver a drug by coupling a drug syringe (10) formed as a syringe to the rear surface. The injection unit (110) is configured to have an injection case (120) through which the drug penetrates, and an injection cover (140) formed on the outside of the injection case (120) and connected to a suction unit (300).
[0060] And, a connecting body (130) is formed on the rear side of the injection case (120) to which the end of the drug syringe (10) is connected, and the connecting body (130) extends from the injection case (120) to the rear side and penetrates the injection cover (140). In addition, a fixing body (131) is formed on the connecting body (130) to fix the drug syringe (10) so that it does not come off, and the fixing body (131) is fixed by a screw connection or a force-fit by pressure with the drug syringe (10), thereby preventing the drug from coming off. And, the injection cover (140) has a protrusion or a groove formed on the outside and is fastened by a force-fit to the outside of the suction part (300), so that the injection case (120) is seated inside the injection cover (140).
[0061] Accordingly, the injection unit (110) of the present invention has a feature of guiding the drug from the drug syringe (10) coupled to the rear to be delivered to the needle (20) as the injection case (120) is installed inside the injection unit (300) by being connected to the suction unit (300).
[0062] (Example 2-7) The drug injection handpiece of the present invention, in Example 2-1, includes: the injection case (120); an injection container (121) in contact with the needle coupling portion (200); and a distribution groove (122) formed inside the injection container (121) and distributing the drug to a plurality of the needles (20).
[0063] (Example 2-8) The drug injection handpiece of the present invention includes an injection groove (123) formed at the center of the injection container (121) in Example 2-7 and through which the drug delivered from the drug syringe (10) passes.
[0064] (Example 2-9) The drug injection handpiece of the present invention includes, in Example 2-8, a first distribution groove (122) formed in the distribution groove (122) and delivered outward from the injection groove (123); and a second distribution groove (122) formed at an end of the first distribution groove (122) and delivering the drug to the needle (20).
[0065] The present invention relates to an injection case (120), and specifically, the injection case (120) is formed inside an injection cover (140) to inject a drug with a needle (20). Referring to FIG. 5, the injection case (120) includes a configuration having a shape corresponding to that of the injection cover (140), and is formed inside the injection cover (140) to deliver the drug with the needle (20). At this time, the injection case (120) is formed with an injection groove (123) through which a drug delivered from a drug syringe (10) passes, and the injection groove (123) is formed at the center of the injection case (120). In addition, a distribution groove (122) is formed on the outside of the injection groove (123), and a first distribution groove (122) is formed in the distribution groove (122) to deliver the drug to the outside from the injection groove (123).

[0066] And the injection case (120) is attached to the rear of the needle coupling part (200). This is to prevent the drug from leaking out by the needle coupling part (200) and the injection case (120) being attached to each other, thereby allowing the drug to be smoothly distributed to the distribution groove (122).

[0073]
[0074] (Example 4-1) The present invention relates to a handpiece for drug injection, and in Example 3-1, the suction part (300) includes a suction case (310) in which the needle coupling part (200) is accommodated inside; and a fixing projection (320) protruding from the front of the suction case (310) and through which the needle (20) passes.
[0075] (Example 4-2) The drug injection handpiece of the present invention is formed inside the suction case (310) in Example 4-1 and includes a receiving space (314) in which the needle coupling part (200) is received.
[0076] (Example 4-3) The drug injection handpiece of the present invention includes a suction space (311) formed on the front of the suction case (310) in Example 4-2 and sucking air between the plurality of fixing protrusions (320).
[0077] (Example 4-4) The drug injection handpiece of the present invention includes a contact protrusion (312) formed on the outside of the suction space (311) and in contact with the temperature control unit (400) in Example 4-3.
[0078] (Example 4-5) The drug injection handpiece of the present invention includes a suction port (313) formed on the outside of the suction space (311) in Example 4-1 and protruding to the outside of the suction case (310) to suck in air.
[0079] (Example 4-6) The drug injection handpiece of the present invention includes a suction tube (315) extending from the suction port (313) in Example 4-1 and connected to a suction pump by being coupled to the main body (500).
[0080] The present invention relates to a suction unit (300), and specifically, the suction unit (300) has a needle coupling unit (200) housed inside, and allows the skin to be pressed against the suction unit by sucking air from the front. Referring to FIGS. 5 and 6, the suction unit (300) can insert a needle (20) to an accurate depth by sucking air to form a vacuum at a location in contact with the skin, and the temperature control unit (400) controls the surface temperature in contact with the skin to reduce pain. At this time, the suction unit (300) is formed in a shape corresponding to the needle coupling unit (200), and a suction case (310) in which the needle coupling unit (200) is housed is formed inside.
[0081] The conventional method of inserting a multi-needle (20) into the skin by pushing the multi-needle (20) into the skin with a strong pressure device has caused fear and rejection in the patients receiving the treatment due to pain caused by the strong pressure, pain caused when multiple needles are inserted into the skin at the same time, and pain caused by drug injection. In addition, when the multi-needle (20) with multiple needles densely arranged is inserted by pulling the skin with vacuum pressure, a phenomenon occurs in which each needle is inserted at an uneven depth depending on the condition and state of the skin. As a result, since the depth of the needles inserted into the skin cannot be inserted consistently, some of the drug is not injected into the skin and may leak out of the skin. In order to prevent this, if the needles are inserted deeply or the vacuum pressure is strong, it causes great pain to the patient receiving the treatment.
[0082] On the other hand, the suction part (300) has a needle coupling part (200) accommodated in the receiving space (314) formed inside the suction case (310), and a suction space (311) formed on the front side to suck air between the fixing protrusions (320). At this time, the suction space (311) sucks air between the temperature control part (400) and the suction case (310), and the suction space (311) is secured by a contact protrusion (312) protruding from the outside of the suction space (311) to the front side. In addition, a suction port (313) protruding from the outside of the suction case (310) is formed, and air is sucked by a suction pipe (315) connected through the suction port (313), so that air is sucked between the fixing protrusion (320) penetrating the temperature control part (400) and the temperature control part (400), and the skin is adhered to the skin with a constant pressure rather than a strong pressure. In addition, the suction pipe (315) is connected to the suction pump by being connected to the main body (500) to prevent detachment and twisting in order to maintain a vacuum state.
[0083] Accordingly, the suction unit (300) of the present invention has a feature of forming a vacuum at a location in contact with the skin to guide the needle (20) to be inserted at an accurate depth.

[0085] (Example 5-1) The present invention relates to a handpiece for drug injection, and in Example 4-1, the temperature control unit (400) includes a control case (410) that is connected to the temperature control device (700) and allows a refrigerant or a heat medium to pass through the inside to control the temperature; and a control member (420) that is coupled to the front of the control case (410) and receives the fixing protrusion (320) and allows the needle (20) to pass through it.
[0086] (Example 5-2) The drug injection handpiece of the present invention includes, in Example 5-1, a refrigerant inlet (411) formed on both sides of the control case (410) and protruding outward so that refrigerant or a heat source is introduced; and a refrigerant discharge port (412) formed at a position corresponding to the refrigerant inlet (411) and through which refrigerant or a heat source is discharged.
[0087] (Example 5-3) The drug injection handpiece of the present invention includes a connecting pipe (550) extending from the coolant inlet (411) and the coolant outlet (412) and connected to the temperature control device (700) in Example 5-2.

[0089] (Example 5-5) The drug injection handpiece of the present invention includes vacuum holes (422) formed at equal intervals on the control plate (421) in Example 5-4 and extending to the rear, and having a vacuum formed inside as the fixing protrusion (320) passes through them.
[0090] The present invention relates to a temperature control unit (400), and specifically, the temperature control unit (400) is a unit that comes into contact with the skin, and can increase the efficacy of a drug and reduce pain as a coolant or a substance supplied by a temperature control device (700) passes through it. Referring to FIG. 6, the temperature control unit (400) is coupled to the front of the suction unit (300), and the fixing protrusion (320) of the suction unit (300) passes through it so that the skin is in close contact with the needle (20), and at the same time, the coolant or substance passes through it so that the in-contact skin can be cooled or warmed. At this time, the temperature control unit (400) is formed with a control case (410) through which the coolant or substance passes, and a control member (420) coupled to the front of the control case (410) is formed.
[0091] And the control case (410) is in close contact with the front of the suction part (300), and a refrigerant inlet (411) and a refrigerant outlet (412) are formed on both sides of the control case (410) so as to protrude outward and through which refrigerant or heat is introduced and discharged. In addition, the refrigerant inlet (411) and the refrigerant outlet (412) are formed at positions facing each other, so that the refrigerant or heat introduced through the refrigerant inlet (411) passes through the interior of the control case (410) and is discharged through the refrigerant outlet (412).
[0092] And the adjusting member (420) formed on the front of the adjusting case (410) has an adjusting plate (421) that comes into contact with the skin and a vacuum hole (422) formed at equal intervals on the adjusting plate (421) and extending downward. At this time, the vacuum hole (422) has a fixing protrusion (320) inserted into it, and the fixing protrusion (320) and the adjusting plate (421) may be formed at the same position or the position of the fixing protrusion (320) may be variable. In this way, as air is sucked from the suction unit (300), the skin is pulled between the vacuum hole (422) and the fixing protrusion (320), so that the needle (20) is effectively inserted into the skin.
[0093] And the temperature of the control plate (421) is controlled as the refrigerant or fruit moves. When the control plate (421) is cooled by the refrigerant, the pain when the needle (20) is inserted into the skin is reduced and hemostasis is achieved as the skin contracts. In addition, when the control plate (421) is warmed by the fruit, the effect can be maximized through thermal stimulation, such as collagen.
[0094] Accordingly, the temperature control unit (400) of the present invention has a feature that can reduce pain and increase the hemostatic effect by cooling or warming the needle (20) when it is inserted into the skin.
