Description

RF Needle Handpiece Tip for Refrigerant Dispensing

[0001] The present invention relates to a handpiece tip for an RF high-frequency device for skin treatment.

[0002] The present invention relates to a refrigerant injection RF needle handpiece tip comprising a refrigerant injection nozzle and an RF needle.

[0003] The present invention relates to a handpiece tip that implements a refrigerant injection function of an RF high-frequency device for skin treatment.

[0004] The present invention relates to a handpiece tip that implements a vacuum suction function of an RF high-frequency device for skin treatment.

[0005] The present invention relates to a handpiece tip that simultaneously implements a refrigerant injection function and a vacuum suction function.

[0006] Although RF high-frequency devices for skin treatment offer excellent therapeutic effects, patients inevitably experience severe pain due to the nature of the treatment, which involves creating abrasions on the skin with high-frequency waves. Consequently, it is common practice to include an anesthesia process, such as applying anesthetic cream like lidocaine, before RF high-frequency skin treatment procedures. However, since refrigerant anesthetic creams take about 30 minutes to become effective after application, they are not highly efficient in terms of time. Furthermore, because the duration of anesthesia varies from patient to patient, there is a side effect where anesthesia must be re-administered in the middle of the procedure if it wears off quickly.

[0007] Accordingly, the applicant has developed an RF high-frequency device for skin treatment in which a refrigerant and a needle are inserted into the vacuum-suctioned skin, as disclosed in Korean Patent Registration No. 2438033 (Aug. 25, 2022), "Handpiece Tip for Refrigerant Spraying of RF High-Frequency Device for Skin Treatment." Furthermore, when the invention of Patent No. 2438033 encountered a problem where the skin was pushed up due to a partition structure, making needle insertion difficult, the applicant disclosed an invention comprising a grid-shaped pressure part that pushes the skin flat through Korean Patent Registration No. 2629325 (January 22, 2024), "Handpiece Tip of RF High-Frequency Device Combined with Refrigerant Spraying Function."

[0008] However, the invention of the aforementioned Korean Patent Registration No. 2629325 has a problem in that the refrigerant becomes liquefied due to the partition structure.

[0009] In addition, regarding the tip of a handpiece for an RF high-frequency device that has both a function of spraying a refrigerant onto the skin and a function of vacuum suctioning the skin according to the invention of Patent No. 2629325, the procedure for local anesthesia typically involves spraying the refrigerant first and then vacuum suctioning the skin, but there is a problem with the vacuum suction function being reduced. This is because, for vacuum suction, negative pressure must be used to create a vacuum inside, whereas the refrigerant spraying function uses positive pressure in the opposite way.

[0010] In addition, the invention of Patent No. 2629325 has a problem in that the refrigerant is difficult to spray evenly because, since the refrigerant is sprayed laterally, a large amount of refrigerant is sprayed onto the skin close to the refrigerant spray nozzle, while a small amount is sprayed onto the skin far away.

[0011] The present invention provides an RF needle handpiece tip for refrigerant injection.

[0012] Specifically, the present invention is,

[0013] Housing having an internal space;

[0014] A pressurizing guide portion formed at the bottom of the housing, extending along the perimeter of the housing, and including one or more residual refrigerant discharge ports;

[0015] A case-shaped pressure part fitted along the inner circumference of the pressure guide part and having a skin contact pressure part formed on the lower surface that contacts the skin;

[0016] A pressure member support having one end connected to the inner side of the housing and the other end connected to the rear end of the pressure member, and comprising an elastic member;

[0017] One or more refrigerant injection nozzles formed at the bottom of the pressurizing part to spray refrigerant toward the skin;

[0018] An RF needle guide portion comprising one or more through holes formed in a vertical direction to the above-mentioned pressure portion;

[0019] An RF needle section comprising at least one RF needle so that the RF needle is inserted toward the skin through the above RF needle guide section;

[0020] The present invention provides an RF needle handpiece tip for refrigerant injection, comprising a linear actuator receiving portion located at the top of the RF needle portion and generating an up-and-down linear reciprocating motion of the RF needle portion.

[0021] Since the refrigerant escapes through the residual refrigerant discharge port formed in the skin contact pressurized part, there is an effect of preventing the refrigerant from liquefying.

[0022] Even if a refrigerant is sprayed onto the skin for local anesthesia and then vacuum suction is performed, the effect of vacuum suction is not significantly reduced.

[0023] Before the needle, the skin first comes into contact with the skin contact pressure part, and after the coolant is sprayed, the skin pushed up into the pressure part guide part is pressed through the pressure part, or is pressed through the pressure part simultaneously with vacuum suction, so the skin is flattened and then the needle is inserted, thus having the effect of allowing the depth of the needle to be carefully controlled even when treating areas with thin skin.

[0024] Since refrigerant spraying is possible along with the needle procedure, it reduces the anesthesia time compared to using anesthetic cream, and allows for immediate anesthesia even after the initial anesthesia wears off, thereby alleviating the patient's fear of the procedure.

[0025] The skin on the inner side of the skin contact pressure part is pressed by the pressure part and flattened, so that needle insertion becomes easier.

[0026] Since the refrigerant injection nozzle is formed around the lower perimeter of the pressurization part, the refrigerant is evenly sprayed throughout the entire treatment area.

[0046] Housing having an internal space;

[0047] A pressurizing guide portion formed at the bottom of the housing, extending along the perimeter of the housing, and including one or more residual refrigerant discharge ports;

[0048] A case-shaped pressure part fitted along the inner circumference of the pressure guide part and having a skin contact pressure part formed on the lower surface that contacts the skin;

[0049] A pressure member support having one end connected to the inner side of the housing and the other end connected to the rear end of the pressure member, and comprising an elastic member;

[0050] One or more refrigerant injection nozzles formed at the bottom of the pressurizing part to spray refrigerant toward the skin;

[0051] An RF needle guide portion comprising one or more through holes formed in a vertical direction to the above-mentioned pressure portion;

[0052] An RF needle section comprising at least one RF needle so that the RF needle is inserted toward the skin through the above RF needle guide section;

[0053] A refrigerant injection RF needle handpiece tip comprising: a linear actuator receiving portion located at the top of the RF needle portion and generating an up-and-down linear reciprocating motion of the RF needle portion.

[0054] The present invention relates to an RF needle handpiece tip (1) for spraying a refrigerant. The RF needle handpiece tip for spraying a refrigerant is coupled to a handpiece of an RF device for skin treatment.

[0055]

[0056] The above RF needle handpiece tip for refrigerant injection is composed of a housing (10), a pressurizing part (20), a pressurizing part support (30), an RF needle part (40), a linear actuator receiving part (50), a negative pressure forming part (60), and a packing part (70).

[0057]

[0058] First, the housing (10) of the present invention will be described.

[0059] The above housing (10) serves to protect each component of the RF needle handpiece tip from the outside by positioning it in the internal space.

[0060] The above housing (10) is composed of a PCB part (11), a body part support part (12), a body part (13), and a pressure part guide part (14).

[0061] The above PCB part (11) is formed on one side of the uppermost part of the housing (10).

[0062] The above PCB part (11) is configured to include a refrigerant transfer pipe PCB coupling hole (111) to which a refrigerant transfer pipe coupling part (1211) is coupled, and a handpiece coupling part (112) for direct coupling with a handpiece of an RF high-frequency device.

[0063] The above body part support part (12) is combined with the above PCB part and is configured to be inserted into the upper interior of the housing, and has the function of supporting the internal components of the body part (13) as a whole.

[0064] The above body support part (12) includes a refrigerant transfer pipe (121) and a fitting member (122).

[0065] The above refrigerant transfer pipe (121) has the function of transferring refrigerant from the handpiece to the refrigerant injection nozzle.

[0066] The above refrigerant transfer pipe (121) includes a refrigerant transfer pipe coupling part (1211) on one side and the other side. One side of the refrigerant transfer pipe coupling part is coupled to the PCB part (11), and the other side is coupled to the upper refrigerant transfer pipe connection part (24) of the pressurizing part and connected to the refrigerant injection nozzle (23).

[0067] The fitting member (122) of the above body part support part (12) is intended to support the internal components of the body part (13) as a whole.

[0068] The fitting member (122) of the above body part support part (12) can be a guide screw.

[0069]

[0070] The above body part (13) extends along the circumference of the body part support part (12) and is formed at the bottom of the body part support part (12), and has the function of protecting the internal components of the housing (10) from the outside.

[0071] The above body part (13) is composed of a body part partition (131) and a body part internal hollow part (132).

[0072] The above body partition (131) is formed in the shape of a partition extending along the perimeter of the housing to protect each component of the RF needle handpiece tip from the outside.

[0073] The above-mentioned internal hollow portion (132) of the body part is an internal space formed by the body part partition, and is formed hollow so that all or part of each component of the RF needle handpiece tip of the present invention is disposed inside the body part.

[0074]

[0075] The above-mentioned pressure guide part (14) is located at the bottom of the body part (13) of the housing (10).

[0076] The above-mentioned pressure guide portion (14) is formed in the shape of a partition extending along the circumference of the lower part of the housing body, and the tip of the lower part of the partition comes into direct contact with the skin.

[0077] The above pressure guide part (14) is configured to guide a case-shaped pressure part (20) that is fitted along the circumference of the inner side of the pressure guide part.

[0078] The above-mentioned pressure guide section (14) is composed of a residual refrigerant discharge section (141), a refrigerant injection area section (142), and a skin contact pressure guide section (143).

[0079] The above residual refrigerant discharge section (141) consists of one or more residual refrigerant discharge ports formed in the partition wall of the pressurizing section guide section (14). This is because, when the refrigerant is sprayed, the refrigerant remaining after being applied to the skin cools the pressurizing section, causing the refrigerant to become liquid rather than vaporize; therefore, a discharge port is provided to allow the refrigerant remaining after being applied to the skin to naturally escape.

[0080] The above residual refrigerant discharge port may be formed along the perimeter of the lower partition of the pressurized guide part (14) to prevent liquefaction of the refrigerant as much as possible.

[0081] The above residual refrigerant discharge port can be any shape to prevent the liquefaction of the refrigerant as much as possible.

[0082] The refrigerant injection area (142) is for specifying the refrigerant injection area and refers to a hollow portion inside the partition wall equipped with a residual refrigerant discharge portion (141) at the bottom of the pressurizing guide portion (14).

[0083] The above-mentioned pressure guide part (14) or refrigerant injection area part (142) may be made of a transparent material so that the treatment area can be easily checked with the naked eye.

[0084] The above skin contact pressure guide part (143) is the lower tip of the pressure guide part (14) and is the part that comes into direct contact with the skin. The above skin contact pressure guide part (143) serves to specify the treatment area inside the skin contact pressure guide part.

[0085]

[0086] The pressurizing part (20) of the present invention will be described.

[0087] The above-mentioned pressure part (20) is intended to flatten the skin by applying pressure and pushing it out. This is because when the skin is pressed by the lower skin contact pressure part guide of the pressure part guide part (14) that contacts the skin, the skin is pushed up between the coolant injection area part (142), making it difficult to insert the RF needle due to the elasticity of the skin. Therefore, a technical configuration that applies pressure to flatten the skin is required.

[0088] The above-mentioned pressure member (20) is configured in a case shape that fits along the circumference of the inner side of the pressure member guide member, and includes a skin contact pressure member (21), an RF needle guide member (22), a refrigerant injection nozzle member (23), and a refrigerant transfer pipe connection member (24).

[0089] The above skin contact pressure part (21) is the lower surface of the pressure part (20) that comes into direct contact with the skin. The above skin contact pressure part (21) serves to flatten the skin by pressing and pushing the skin.

[0090] The above RF needle guide part (22) is configured to guide the RF needle, is formed in a vertical direction to the above pressure part, and consists of one or more through holes.

[0091]

[0092] The above refrigerant injection nozzle part (23) is for spraying refrigerant toward the skin exposed to the above refrigerant injection area part (142).

[0093] The above refrigerant injection nozzle part (23) has the function of spraying the refrigerant generated from the RF high-frequency device towards the skin when it is delivered through the refrigerant transfer pipe (121).

[0094] The above refrigerant injection nozzle section (23) includes one or more refrigerant injection nozzles (231) formed in the pressurizing section so that the refrigerant is sprayed toward the skin.

[0095] Specifically, the refrigerant injection nozzle section (23) is composed of one or more refrigerant injection nozzles (231) arranged along the lower circumference of the pressurizing section (20).

[0096] The above refrigerant injection nozzle section (23) is composed of one or more refrigerant injection nozzles (231) formed around the lower RF needle guide section (22) of the above pressurizing section (20).

[0097] Specifically, the refrigerant injection nozzle section (23) is composed of one or more refrigerant injection nozzles (231) arranged along the circumference of the pressurizing section (20) around the lower RF needle guide section (22) of the pressurizing section (20).

[0098] For example, the refrigerant injection nozzle (231) may be composed of a plurality of refrigerant injection nozzles (231) arranged along the circumference of the pressurizing part (20) around the lower RF needle guide part (22) so that the refrigerant is evenly sprayed.

[0099] The above refrigerant injection nozzle (231) may have a refrigerant injection hole formed in a rectangular or elliptical shape so that the refrigerant is evenly sprayed, but is not limited thereto.

[0100] The refrigerant injection of the above refrigerant injection nozzle (231) can be injected according to a sequence preset by the control unit.

[0101] Specifically, the refrigerant injection of the refrigerant injection nozzle (231) can be injected according to a preset sequence by the control unit when a signal is input through the input unit (90).

[0102] For example, after the refrigerant is sprayed toward the skin from the above-mentioned refrigerant spray nozzle, pressure is transmitted to the skin contact pressure part through the pressure part support, causing the skin in the refrigerant spray area formed inside the pressure part guide part to be pressed and spread, and one or more RF needles can be controlled to be inserted into the skin spread by the skin contact pressure part. This is because it is effective to pressurize the skin before inserting the RF needle in order to make the RF needle insertion depth uniform, so pressure is transmitted to the skin contact pressure part after the refrigerant is sprayed.

[0103] For example, the above refrigerant injection sequence can be controlled so that at least one refrigerant is injected from the time pressure begins to be transmitted to the skin contact pressure part through the pressure part support until the skin comes into contact with the skin contact pressure part.

[0104] For example, the above refrigerant injection sequence can be controlled so that the refrigerant is injected multiple times from the time pressure begins to be transmitted to the skin contact pressure part through the pressure part support until the skin comes into contact with the skin contact pressure part.

[0105] In this regard, if the refrigerant is sprayed all at once, a large amount of refrigerant is required, and in such cases, residual refrigerant may not be able to fully escape through the residual refrigerant discharge port. Therefore, in such cases, it is advisable to spray small amounts in bursts. Additionally, if a large amount of refrigerant must be sprayed due to the characteristics of the affected area, spraying it all at once may lead to frostbite; therefore, in such cases, it is advisable to spray small amounts in bursts.

[0106] Additionally, the refrigerant injection of the refrigerant injection nozzle (231) may be injected temporarily or repeatedly according to the time, speed, sequence, and one or more specified refrigerant injection holes where the refrigerant is injected, which are preset by the control unit (80).

[0107] Meanwhile, the control unit (80) and input unit (90) may be configured in a refrigerant injection RF needle handpiece or main body to which a refrigerant injection RF needle handpiece tip is coupled.

[0108] The refrigerant transfer pipe connection part (24) is located at the top of the refrigerant pressurization part, and one side is connected to the refrigerant transfer pipe, and the other side is connected to the refrigerant injection nozzle (23).

[0109]

[0110] The pressurized support member (30) of the present invention will be described.

[0111] The above-mentioned pressure support member (30) has one end connected to the inside of the housing (10) and the other end connected to the rear end of the pressure member (20), serving to provide elasticity to the pressure member (20).

[0112] The above-mentioned pressure support member (30) includes an elastic member (31) in the shape of a rod.

[0113] The above-mentioned pressure support member (30) may be formed in the shape of a single rod or in the shape of multiple rods.

[0114] Additionally, the elastic member (31) of the above-mentioned pressure support (30) may be made up of a single member or a plurality of members.

[0115] The above-mentioned pressure support (30) may be composed of a bolt with a spring attached. Alternatively, it may be composed of a pogo pin with a spring included on the inside.

[0116]

[0117] The RF needle part (40) of the present invention will be described.

[0118] The above RF needle part (40) is formed at the upper end based on the pressure part (20) inside the housing (10).

[0119] The above RF needle portion (40) is composed of one or more RF needles (41) that are vertical for insertion into the skin and an RF needle plate (42) to which the RF needles are combined.

[0120] The RF needle (41) of the above RF needle section (40) is characterized by penetrating the RF needle guide section (22) and being inserted in the direction of the skin of the refrigerant injection area section (142) located at the bottom of the RF needle guide section (22).

[0121]

[0122] The linear actuator receiving part (50) of the present invention will be described.

[0123] The above linear actuator receiving portion (50) is formed on the upper part of the RF needle portion (40) as a component of the RF needle handpiece tip for refrigerant injection, in which a linear actuator configured in the RF needle handpiece for refrigerant injection is received.

[0124] When the force of linear reciprocating motion from the linear actuator is transmitted to the linear actuator receiving part (50), the force of vertical linear reciprocating motion is transmitted from the linear actuator receiving part (50) to the RF needle part (40), thereby performing vertical linear reciprocating motion.

[0125]

[0126] The sound pressure forming part (60) of the present invention will be described.

[0127] The above-mentioned sound pressure forming unit (60) is configured to receive sound pressure energy generated from an RF high-frequency device and form a vacuum inside the housing (10). The sound pressure formation is performed inside the housing (10) and inside the pressurizing unit (20).

[0128] When the above negative pressure energy is transmitted, the skin of the refrigerant injection area (142) is sucked in due to the negative pressure. As described above, when the skin is sucked in by vacuum, precise control of the insertion depth of the RF needle becomes easier.

[0129] At this time, the vacuum-suctioned skin is pressurized by the pressurizing unit; however, if the pressure is excessive and the skin is spread too thin, the vacuum loses its meaning, and if the pressure is too weak, there is a problem where the RF needle cannot be easily inserted due to the skin's elasticity, so an appropriate level of pressure must be applied.

[0130] The sound pressure generation of the present invention can be performed according to a preset sequence.

[0131] Specifically, the sound pressure generation of the present invention can be controlled according to a sequence preset by a control unit.

[0132] In addition, the sound pressure generation of the present invention can be generated according to a preset sequence by the control unit when a signal is input through the input unit (90).

[0133] The above-mentioned negative pressure generation can be controlled through a control unit so that pressure is transmitted to the skin contact pressure part through the pressure support, and is generated before, after, or simultaneously with contact with the skin contact pressure part.

[0134] Specifically, the negative pressure generation of the present invention may be configured such that, after pressure begins to be transmitted to the skin contact pressure part through the pressure part support, at least one refrigerant is sprayed before, after, or simultaneously with contact with the skin contact pressure part, and the skin is vacuum-suctioned before, after, or simultaneously with the spraying of the refrigerant.

[0135] For example, the negative pressure generation of the present invention may be configured such that at least one refrigerant is sprayed from the time pressure begins to be transmitted to the skin contact pressure part through the pressure part support until the skin comes into contact with the skin contact pressure part, and the skin is vacuum-suctioned before, after, or simultaneously with the spraying of the refrigerant.

[0136] In addition, after pressure begins to be transmitted to the skin contact pressure part through the pressure part support, at least one refrigerant spray is performed before the skin comes into contact with the skin contact pressure part, and then at least one vacuum suction is performed after the skin comes into contact with the skin contact pressure part. This is because refrigerant spraying uses positive pressure, whereas vacuum suction uses negative pressure. When pressure begins to be transmitted to the skin contact pressure part through the pressure part support, the pressure part descends; at this time, until the skin comes into contact with the skin contact pressure part, the refrigerant discharge port is open, allowing refrigerant spraying to occur through positive pressure. Afterward, when the skin comes into contact with the skin contact pressure part, the refrigerant discharge port closes, sealing the inside of the housing, thereby enabling negative pressure. Therefore, vacuum suction is performed at this time.

[0137] The above-mentioned negative pressure generation is performed according to the above-mentioned preset sequence, but pressure is transmitted to the skin contact pressure part through the pressure part support, and at least one vacuum suction may be performed after the skin comes into contact with the skin contact pressure part. This is because, when the refrigerant injection function is unnecessary, positive pressure is not utilized, so negative pressure is generated immediately regardless of the refrigerant injection sequence. As described above, when the skin comes into contact with the skin contact pressure part, the refrigerant discharge port closes and the inside of the housing is sealed, thereby enabling negative pressure, and thus vacuum suction is performed at this time.

[0138] The RF needle handpiece tip for refrigerant injection of the present invention can perform appropriate vacuum suction and skin pressure according to preset sound pressure and pressure levels through the control unit (80) of the RF high-frequency device.

[0139]

[0140] The packing part (70) of the present invention will be described.

[0141] The packing portion (70) of the present invention is composed of one or more packings (71) that are inserted between gaps or joints inside the housing (10) to maintain a vacuum state inside the housing (10) when negative pressure is formed.

[0142] The above packing portion (70) includes one or more packings formed in the refrigerant transfer pipe (121) or the refrigerant transfer pipe connection portion (24).

[0143] For example, the packing portion (70) includes one or more refrigerant transfer pipe packings (711) formed on one or both sides of the refrigerant transfer pipe (121). At this time, the packing portion (70) may be composed of one or more packings (711) formed on one or both sides of the refrigerant transfer pipe coupling portion (1211).

[0144] Additionally, the packing portion (70) includes one or more refrigerant transfer pipe connection packings (712) formed on one or both sides of the refrigerant transfer pipe connection portion (24).

[0145] The above packing portion (70) includes one or more pressure portion packings (713) formed in the pressure portion (20). Specifically, the packing portion (70) may be composed of one or more packings (713) formed in a case-shaped pressure portion (20) that is fitted along the circumference of the inner side of the pressure portion guide portion (14).

[0146] The above packing can be an O-ring.

[0147]

[0148] The configuration of the RF needle handpiece tip for refrigerant injection according to the present invention can be as follows.

[0149] The present invention relates to a refrigerant injection RF needle handpiece tip comprising a refrigerant injection nozzle and an RF needle, wherein

[0150] The RF needle handpiece tip for refrigerant injection of the present invention is,

[0151] Housing (10) having an internal space;

[0152] A pressure guide portion (14) formed extending along the circumference of the housing at the bottom of the housing;

[0153] A case-shaped pressure part (20) including a skin contact pressure part that is fitted along the inner circumference of the pressure part guide part and has one end in contact with the skin;

[0154] A pressure member support (30) having one end connected to the inside of the housing and the other end connected to the rear end of the pressure member, and an elastic member configured thereon; and

[0155] It may be formed by including a negative pressure forming part (60) configured inside the housing so that the skin is vacuum-suctioned to the skin contact pressure part.

[0156] In addition, the above-mentioned sound pressure generation can be performed according to a preset sequence.

[0157] At this time, regarding the aforementioned preset sequence, pressure is transmitted to the skin contact pressure part through the pressure part support, and after the skin comes into contact with the skin contact pressure part, at least one vacuum suction is performed.

[0158]

[0159] Let's examine the operating mechanism of the above-mentioned RF needle handpiece tip for refrigerant injection.

[0160] The RF needle handpiece tip for refrigerant injection of the present invention operates by receiving a signal from the control unit of an RF high-frequency device and can be operated in a sound-pressure RF needle insertion mode and a sound-pressure RF needle insertion mode.

[0161]

[0162] [Silent Pressure Refrigerant Injection RF Needle Insertion Mode]

[0163] The silent pressure refrigerant injection RF needle insertion mode is used when performing procedures without generating negative pressure energy.

[0164] The operation method of the above-mentioned silent pressure refrigerant injection RF needle insertion mode is as follows.

[0165] The above-mentioned RF needle handpiece tip for refrigerant injection is,

[0166] After refrigerant is sprayed toward the skin from one or more refrigerant spray nozzles (231), pressure is transmitted to the skin contact pressure part through the pressure part support, and the skin of the refrigerant spray area formed inside the pressure part guide part is pressed and spread out.

[0167] One or more RF needles are controlled to be inserted into the skin spread by the above-mentioned skin contact pressure part.
