Description

A component for RF needle tips for pushing and stretching the skin

[0001] The present invention relates to a member for an RF needle tip for pushing and stretching skin coupled to an RF needle tip for skin treatment.

[0002] While RF high-frequency devices for skin treatment are highly effective, the high-frequency nature of the device can inevitably cause significant pain to patients. Therefore, prior to RF high-frequency skin treatment, anesthesia, such as the application of anesthetic creams like lidocaine, is typically administered. However, refrigerant anesthetic creams take approximately 30 minutes to take effect, making them inefficient. Furthermore, the duration of anesthesia varies from patient to patient, requiring re-anesthesia mid-procedure if the anesthesia wears off too quickly.

[0003] Accordingly, the applicant has developed a skin treatment RF high frequency device in which the skin is vacuum-sucked and a refrigerant and a needle are inserted into the vacuum-sucked skin, as disclosed in Korean Patent Registration No. 2438033 (August 25, 2022), "Handpiece tip for RF high frequency device for skin treatment." In addition, when the patented invention of No. 2438033 had a problem in that the skin was pushed up due to the body structure, making it difficult to insert a needle, the applicant has disclosed an invention in which a grid-shaped pressurizing part is configured to push the skin flat through Korean Patent Registration No. 2629325 (January 22, 2024), "Handpiece tip for RF high frequency device with refrigerant injection function."

[0004] However, the invention of the above Korean Patent Registration No. 2629325 has a problem in that the refrigerant is sprayed inside the body, and over time, the refrigerant liquefies inside the body. In addition, there is a problem in that the refrigerant is not sprayed evenly due to the bulkhead structure.

[0005] To address the issue of needle liquefaction, a physical means is needed to ensure that skin contact occurs prior to the needle, and a local anesthetic refrigerant is injected between the skin and the needle, allowing the refrigerant to be injected from outside the body. Furthermore, to address the issue of uneven refrigerant injection, technological improvements to the baffle structure are needed to ensure that the refrigerant is not blocked in the injection area.

[0006] The present invention provides a member for an RF needle tip for pushing and stretching skin, which includes a support so that a needle hole into which a needle is inserted and a skin pressure plate in contact with the skin are spaced apart and connected.

[0007] Specifically,

[0008] A support joint configured at the rear end of the support joint to be coupled to the RF needle tip;

[0009] An elastic member coupled to the inside of the support member to provide elasticity to the support member;

[0010] A skin pressure frame formed in a frame shape along the hollow circumference and connected to the front end of the support so as to be in contact with the skin;

[0011] A component for an RF needle tip for pushing and stretching the skin is provided, which comprises a treatment area-specific portion formed hollow inside a skin pressure frame so that the RF needle can pass through.

[0012] It has the effect of solving the problem of the injected refrigerant liquefying inside the body.

[0013] As the refrigerant is physically sprayed from the outside of the body, the body is cooled by continuous refrigerant spraying, which has the effect of preventing liquefaction of the refrigerant, which occurs when this temperature is the same as the vaporization temperature of the refrigerant.

[0014] Additionally, the skin pressure plate pushes the skin to flatten it, thereby maintaining the depth of needle insertion and the amount of coolant within the same treatment area evenly, which allows for precise control of the amount of coolant and high-frequency energy.

[0015] The skin pressure plate has the effect of pushing the skin out and flattening it, making needle insertion easier.

[0016] Since refrigerant injection is possible along with the needle procedure, the anesthesia time is shortened compared to when anesthesia cream is used, and anesthesia can be resumed immediately after the anesthesia wears off, which is effective in relieving the patient's fear of the procedure.

[0017] Since the treatment area inside the skin pressure plate that comes into contact with the skin can be visually confirmed, it is effective in making it easy for the practitioner to specify the treatment area.

[0025] Figure 8 is a cross-sectional view comparing the before and after pressurization of a fixed assembly according to the present invention.

[0026] A member for an RF needle tip for pushing and stretching the skin according to the present invention is:

[0027] A skin pressure frame formed in a frame shape along the hollow circumference and connected to one end of a support so as to be spaced apart from the RF needle tip and in contact with the skin;

[0028] A treatment area-specific part formed hollow inside the above skin pressure frame;

[0029] A support member that is connected to the skin pressure frame at one end and has a support member formed at the other end to be connected to the RF needle tip or a border member, and extends vertically;

[0030] It is composed of an elastic member formed on the inside of the support member to provide elasticity when pressure is applied to the RF needle tip.

[0031] The present invention relates to a member (100) for an RF needle tip for pushing and stretching the skin. The member for the RF needle tip for pushing and stretching the skin is a member that is used by being combined with an RF needle tip (2) for skin treatment.

[0032]

[0033] The RF needle tip member for pushing and stretching the above skin is coupled to an RF needle tip in which the coolant injection hole is not centered with respect to the needle plate of the RF needle tip in order to prevent the coolant from liquefying when the coolant is injected.

[0034] The above refrigerant injection hole is connected to the RF needle tip near the edge of the needle plate of the RF needle tip, as illustrated in Fig. 4.

[0035]

[0036] The RF needle tip member (100) for pushing and stretching the skin is composed of a support joint (110), a support (120), and a skin pressure member (130).

[0037] The RF needle tip member (100) for pushing and stretching the above skin may further include a border member (140).

[0038] The RF needle tip member (100) for pushing and stretching the above skin may further include a skin contact sensor unit (150).

[0039] First, the support joint (110) will be described. The support joint (110) is composed of a joint member for being coupled to an RF needle tip for skin treatment, and is formed at one end of the support member to be coupled to the RF needle tip or the edge member.

[0040] The above support joint (110) is configured at the rear end of the support.

[0041] The above support joint (110) may be fixedly coupled (A) or detachably coupled (B) to the RF needle tip for skin treatment.

[0042]

[0043] Looking at an example of a fixed connection (A) of the above support joint (110), it can be integrally connected with the RF needle tip for skin treatment. For example, the rear end of the support (120) is inserted into the inside of the RF needle tip for skin treatment and fixedly connected to the RF needle tip for skin treatment by being screwed through the support joint (110).

[0044] As another example, the rear end of a support (120) may be inserted into the inside of the RF needle tip for skin treatment and fixedly connected to the RF needle tip for skin treatment by being fixedly fixed by a magnet through the support joint (110). In this case, the support (120) must be made of a material capable of being attached to a magnet, such as iron.

[0045]

[0046] Looking at an example of a detachable joint (B) of the above support joint (110), it is configured by further including a frame member (140).

[0047] The above-mentioned frame member (140) is composed of a support insertion hole (141), an RF needle tip coupling portion (142), and an RF needle tip insertion portion (143).

[0048] The above-mentioned frame member (140) has a partition formed along the circumference of the RF needle tip for skin treatment, and a hollow RF needle tip insertion portion (143) is formed between the partitions. The RF needle tip for skin treatment is inserted into the hollow RF needle tip insertion portion (143) of the above-mentioned frame member (140), thereby being connected.

[0049] The above support insertion hole (141) is formed on the inside of the frame member (140) and includes a connecting member so as to be connected to the rear end of the support member.

[0050] The above RF needle tip coupling part (142) is for attachment to and detachment from the above therapeutic RF needle tip, and can be anything that can be attached to the RF needle tip.

[0051] The above RF needle tip coupling part (142) is configured to be coupled with the edge member coupling part (210) on the outer surface of the therapeutic RF needle tip so that the support coupling part (110) can be detached by elastic force.

[0052] For example, the RF needle tip coupling portion (142) may be formed of a hook (142a), in which case the hook (142a) is positioned on the side of the edge member so as to be detached from the therapeutic RF needle tip. In addition, the hook (142a) may include an elastic member such as a spring and be coupled with the edge member coupling portion (210) on the outer surface of the therapeutic RF needle tip so that the support coupling portion (110) can be detached by elastic force.

[0053]

[0054] The support (120) of the present invention will be described.

[0055] The above support (120) has one end connected to the RF needle tip and the other end connected to the skin pressure frame.

[0056] The above support (120) is a vertically extending support so that the RF needle tip for skin treatment and the RF needle tip member for pushing and stretching the skin are spaced apart and connected. The above support (120) may be configured in a rod shape or a bar shape and may have any shape extending vertically.

[0057] At this time, the front end of the support (120) is connected to the skin pressure frame (131).

[0058] The rear end of the above support (120) is coupled to the RF needle tip (200) when the support joint (110) is fixed, and is coupled to the frame member (140) when the support joint (110) is detachable.

[0059] The support (120) includes an elastic member (121) to provide elasticity before needle insertion. The elastic member (121) may be any elastic member. For example, the elastic member may be a spring. Additionally, the support (120) may be a spring pogo pin including an elastic member such as a spring.

[0060] The above support (120) must be formed so that the area where the refrigerant is sprayed is not sealed to prevent the refrigerant from liquefying. For example, a body structure that completely seals the area where the refrigerant is sprayed should be avoided as this can cause the refrigerant to liquefy when blocked by the bulkhead the moment it is sprayed.

[0061] Looking at the operating principles of the above support (120) and elastic member (121), when pressure is applied to the support by external pressure, elastic force is provided to the support (120) by the elastic member (121), and the skin combined with the support (120) is pushed by the skin pressure member (130) to become flat.

[0062]

[0063] Let us examine the skin pressure portion (130) of the present invention.

[0064] The above skin pressure portion (130) is a portion that comes into direct contact with the skin and is connected to one end of the support (120) so as to be spaced apart from the RF needle tip. The skin pressure portion (130) receives elastic force from the support (120) and pushes the skin, thereby flattening the skin.

[0065] The above skin pressure part (130) is composed of a skin pressure frame (131) formed in a frame shape along a hollow perimeter and a treatment area-specific part (132) formed in a hollow shape on the inside of the skin pressure frame.

[0066] The above skin pressure frame (131) can be any shape, such as a polygon, circle, or curve, depending on the shape of the hollow body, and can be a frame shape with angles or a frame shape without angles.

[0067] The above treatment area-specific part (132) is formed as a hollow part inside the skin pressure frame, and an RF needle is inserted and a coolant is sprayed through the hollow part. The above treatment area-specific part (132) specifies the treatment area inside the skin pressure frame.

[0068]

[0069] Let us examine the skin contact sensor unit (150) of the present invention.

[0070] The RF needle tip member for pushing and stretching the skin of the present invention may further include a skin contact sensor unit (150).

[0071] The above skin contact sensor unit (150) is for detecting whether the skin pressure frame (131) of the skin pressure unit (130) touches the skin.

[0072] This is to ensure that the refrigerant is sprayed at the moment of contact with the skin.

[0073]

[0074] The RF needle tip (200) for skin treatment of the present invention will be examined.

[0075] The above-mentioned RF needle tip (200) for skin treatment is an RF needle tip (200) that is coupled to a handpiece tip of a RF high-frequency device for skin treatment with a needle insertion and refrigerant injection function.

[0076] The RF needle tip (200) may have a border member joining portion (210) formed on the outer surface to be joined with the RF needle tip joining portion (142) of the border member.

[0077] In addition, the RF high frequency device for skin treatment may further have a function of providing negative pressure to suction the skin.

[0078]

[0079] The above RF high frequency device for skin treatment is,

[0080] When pressure is applied to the RF needle tip, elastic force is generated from the support (120),

[0081] As the above elasticity is provided to the skin contact frame, the skin is stretched,

[0082] The refrigerant is sprayed from the refrigerant injection hole provided in the RF needle tip,

[0083] It can be a handpiece tip of a skin treatment RF high frequency device including a control unit so that a needle is inserted after the above refrigerant is sprayed.

[0084]

[0085] The present invention relates to a member for an RF needle tip for pushing and stretching skin, which includes a support so that a needle hole into which a needle is inserted and a skin pressure plate in contact with the skin are spaced apart and connected, and has industrial applicability.
