AI Technical Summary
The existing radio frequency instruments cannot have both nutritional solution injections when performing radio frequency operations, and the effect of supplementing nutrient solution injection after radio frequency treatment is greatly reduced, so it is impossible to accurately inject nutrient solution at the radio frequency treatment location.
An operating handle is designed, including a housing, a control unit, a liquid feeding unit and a needle. The needle includes a needle base, a needle tube group and an electrode group. The electrodes of the electrode group are needle-shaped and can enter the epidermis to a certain depth. The liquid feeding unit and the needle tube group can inject nutrient solution into the skin synchronously.
The electrode enters the subepideria without directly acting on the epidermis, which reduces the risk of scalds in the epidermis, shortens the stimulation cycle, and improves the treatment effect. At the same time, synchronous injection of nutrient solution improves the skin's absorption effect of nutrient solution, and relieves the pain during the treatment process through anesthetic ingredients.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of radio frequency instruments, in particular to an operating handle and a radio frequency instrument provided with the operating handle. Background Art
[0002] Radiofrequency devices use low-frequency electromagnetic waves to act on the human body or skin, causing water molecules in the tissue to move at high speed to generate heat. This endogenous heat effect can cause proteins to coagulate and lose their activity, and eventually cause them to fall off through the body's rejection, thereby achieving the purpose of treatment. However, the electrodes of most existing radiofrequency devices act on the epidermis, which is prone to the risk of scalding the epidermis. In addition, since the electrodes of existing radiofrequency devices are surface stimulation, they have the disadvantages of a long stimulation cycle and limited effect.
[0003] In order to solve the above-mentioned shortcomings, a small number of new radio frequency devices currently use microneedles as electrodes. When used, the microneedles enter the human epidermis to a certain depth, and generate radio frequency waves at a specific depth under the skin through radio frequency, which act on the water molecules in the collagen, causing the bipolar water molecules to vibrate and rotate at high speed, generating heat through friction, and achieving the effect of heating the dermal collagen. However, the shortcomings of this new radio frequency device are: it is impossible to inject nutrient solution while performing radio frequency operation; and if the nutrient solution is injected again after completing the radio frequency treatment, its use effect will be greatly reduced, and it is impossible to accurately inject the nutrient solution at the location of radio frequency treatment, and it is also necessary to use other instruments and equipment for operation; it can be seen that the function and practicality of the existing new radio frequency device still need to be improved and perfected. Summary of the invention
[0004] In order to solve the above problems, the main purpose of the utility model is to provide an operating handle with the functions of injection and sending radio frequency waves.
[0005] Another object of the utility model is to provide a radio frequency instrument provided with the above-mentioned operating handle.
[0006] In order to achieve the main purpose of the utility model, the utility model provides an operating handle, including a shell and a control unit, the control unit is arranged in the shell, wherein the operating handle also includes a liquid feeding unit and a needle, the liquid feeding unit is installed in the shell and electrically connected to the control unit, the needle includes a needle seat, a needle tube group and an electrode group, the needle seat is installed on the shell or the liquid feeding unit, the liquid outlet of the liquid feeding unit is connected to the needle head, the needle seat has a flow channel, the needle tube group and the electrode group are both installed on the needle seat, the flow channel connects the needle tube group and the liquid outlet, the electrode of the electrode group is needle-shaped, and the electrode group is electrically connected to the control unit.
[0007] As can be seen from the above, the electrodes of the electrode group are designed to be needle-shaped, so that the electrodes can enter the epidermis to a certain depth, and then the radio frequency generates radio frequency waves at a specific depth under the skin, which acts on the water molecules in the collagen, causing the bipolar water molecules to vibrate and rotate at high speed, generating heat through friction, and thus achieving the effect of heating the dermal collagen. Since the electrodes enter under the epidermis and do not directly act on the epidermis, the risk of epidermal burns can be reduced, and the stimulation cycle can be shortened to improve the effect. In addition, by providing a liquid feeding unit and a syringe group, when the electrode group emits radio frequency waves to the skin, nutrient solution can be injected into the skin through the liquid feeding unit and the syringe group at the same time, so as to improve the skin's absorption of the nutrient solution. At the same time, when the injected nutrient solution contains anesthetic components (such as sodium hyaluronate containing anesthetics on the market), the anesthetic components in the nutrient solution can also relieve the pain during radio frequency treatment and when the electrode group punctures the skin, thereby improving the user experience.

[0012] A further solution is that an end of the connecting portion close to the extending end of the needle tube assembly is provided with an inclined surface, and the inclined surface is inclined to the extending direction.

[0017] As can be seen from the above, this design is conducive to the miniaturization of the needle, so that the operator can observe the treatment area and avoid repeated treatment of the same treatment area.
[0018] A further solution is that the needle tube group includes more than two needle tubes, and the more than two needle tubes are distributed along the width direction; the electrode group includes a positive electrode and a negative electrode, and the positive electrode and the negative electrode are distributed along the width direction, and the needle tube group is located between the positive electrode and the negative electrode, and the positive electrode and the negative electrode are both needle tube-shaped; the surrounding wall of the positive electrode is coated with an insulating layer, and the surrounding wall of the negative electrode is coated with an insulating layer.
[0019] As can be seen from the above, through the layout design of the needle tube group and the electrode group, each needle tube and each electrode can maintain synchronization and depth of entering the epidermis, thereby ensuring the treatment effect; and an insulating layer is coated on the surrounding wall of the positive electrode and the surrounding wall of the negative electrode, so that the discharge of the positive and negative electrodes is under the skin, thereby ensuring that the epidermis will not be burned.
[0020] A further solution is that the liquid feeding unit includes a liquid storage tube, a liquid feeding rod and a driving mechanism, the liquid storage tube has a liquid storage cavity, a liquid outlet is formed at the first end of the liquid storage tube, and the opening of the liquid storage cavity is formed at the second end of the liquid storage tube, the liquid feeding rod includes a piston and a push rod, the piston is slidably installed in the liquid storage cavity and is sealed adjacent to the cavity wall of the liquid storage cavity, the push rod is connected to the piston and extends out of the liquid storage cavity, the push rod is parallel to the depth direction of the liquid storage cavity, and the driving mechanism can drive the push rod to slide along the depth direction.
[0021] As can be seen from the above, the driving mechanism can drive the liquid feeding rod to move smoothly toward the liquid outlet of the liquid storage tube, thereby enabling the liquid feeding unit to achieve stable and quantitative nutrient solution injection, thereby ensuring both the treatment effect and the safety and rationality of the treatment.
[0022] A further solution is that the push rod is rotatably connected to the piston around its own axis, the push rod is provided with an external thread, the driving mechanism includes a motor and a reducer, the motor shaft of the motor is connected to the input shaft of the reducer, the output shaft of the reducer has an internal thread, the output shaft is sleeved on the push rod, and the internal thread is threadedly connected to the external thread; or a dial is provided at the end of the push rod away from the piston, the driving mechanism is a linear module, and a claw is provided on the slide of the linear module, and the claw is engaged and connected with the dial.

At the same time, it can also avoid excessive vibration when the driving mechanism drives the liquid feeding rod to move, thereby improving the experience of the patient.
[0024] In order to achieve another purpose of the utility model, the utility model provides a radio frequency instrument, including a power supply device, which also includes the above-mentioned operating handle, and the power supply device is electrically connected to the control unit.

[0035] Operating handle embodiment
[0036] Reference Figure 1 and Figure 2 The operating handle 100 includes a housing 1, a control unit 2, a needle 3 and a liquid feeding unit 4. The housing 1 is preferably pen-shaped, the control unit 2 and the liquid feeding unit 4 are arranged in the housing 1, the needle 3 is installed on the housing 1 or the liquid feeding unit 4, and the needle 3 is connected to the liquid outlet 411 of the liquid feeding unit 4.
[0037] Combination Figure 3 and Figure 4 The needle 3 includes a needle seat 31, a needle tube group 33 and an electrode group 32. The needle seat 31 is installed on the housing 1 or the liquid feeding unit 4, and the needle seat 31 is connected to the liquid outlet 411 of the liquid feeding unit 4; the needle seat 31 has a flow channel 310. The needle tube group 33 and the electrode group 32 are both installed on the needle seat 31, and the flow channel 310 connects the needle tube group 33 and the liquid outlet 411; the electrode of the electrode group 32 is needle-shaped, and the motor 431 group is electrically connected to the control unit 2.
[0038] Preferably, the needle seat 31 has a connecting portion 311 and a mounting portion 312, the mounting portion 312 is used to connect to the housing 1 or the liquid feeding unit 4, and the needle tube group 33 and the electrode group 32 are mounted on the connecting portion 311. Preferably, as in the present embodiment, the connecting portion 311 and the mounting portion 312 both extend along the extension direction of the needle tube group 33, and the connecting portion 311 and the mounting portion 312 are distributed along the extension direction of the needle tube group 33; of course, as another optional solution, the extension direction of the connecting portion 311 can also be distributed at an obtuse angle to the extension direction of the mounting portion 312, so that the connecting portion 311 is bent relative to the mounting portion 312.
[0039] In order to avoid the risk of shrinkage of the connection part 311 after molding, as in the present embodiment, a groove is molded in the connection part 311, and the groove is molded into an opening on the side wall of the connection part 311, and the groove runs through the end of the connection part 311 close to the mounting part 312, so that the groove is connected to the flow channel 310, and the groove is filled with an adhesive 3111 (such as glue) to seal the groove and prevent the nutrient solution from leaking out of the connection part 311 from the groove. Of course, as another optional solution, the connection part 311 can also be directly injection molded into a solid structure, that is, there is no groove structure, but this structure may increase the risk of shrinkage of the connection part 311 during molding and cooling.
[0040] Combination Figure 5In the extension direction of the needle tube group 33, the first length L1 of the needle tube group 33 extending from the connecting portion 311 is preferably between 1 mm and 2 mm, the first length L1 of the electrode group 32 extending from the connecting portion 311 is preferably also between 1 mm and 2 mm, and the length of the needle tube group 33 extending from the connecting portion 311 is preferably equal to the length of the electrode group 32 extending from the connecting portion 311; and by designing the length of the needle tube group 33 extending from the connecting portion 311 and the length of the electrode group 32 extending from the connecting portion 311, the needle seat 31 can limit the maximum depth of the needle tube group 33 and the electrode group 32 entering the epidermis, so as to prevent the needle tube group 33 or the electrode group 32 from entering the epidermis too deeply, thereby preventing skin tissue damage or even nerve damage.
[0041] In addition, the first diameter D1 of the needle tube 331 of the needle tube group 33 is preferably between 0.1 mm and 0.3 mm, and the second diameter D2 of the electrode of the electrode group 32 is preferably between 0.1 mm and 0.3 mm, and the first diameter D1 of the needle tube 331 is preferably equal to the second diameter D2 of the electrode. By designing the first diameter D1 of the needle tube 331 and the second diameter D2 of the electrode, the needle tube 331 and the electrode are both in the shape of micro needles, so that when the operating handle 100 is used to treat the patient, the pain of the needle tube 331 and the electrode entering the subcutaneous tissue can be reduced, and it is also conducive to the miniaturized design of the needle head 3. The miniaturized design of the needle head 3 is more convenient for the operator of the operating handle 100 to observe the treatment area, and it is better to avoid repeated treatment of the same treatment area. Among them, the end of the electrode of the electrode group 32 is preferably the same as the needle tube 331, that is, the end of the electrode has an elliptical surface, and the elliptical surface is inclined to the axial direction of the electrode; of course, as another optional scheme, the end of the electrode can also be conical; by designing the end of the electrode, the electrode can better enter the epidermis.
[0042] Furthermore, combined Figure 6 In the extension direction of the needle tube assembly 33, the second length L2 of the needle seat 31 extending from the housing 1 is preferably between 20 mm and 26 mm; and the width of the extending end of the connecting portion 311 of the needle seat 31 (i.e., the end of the connecting portion 311 away from the mounting portion 312) is preferably between 3 mm and 8 mm; wherein the width direction of the connecting portion 311 is perpendicular to the extension direction of the needle tube assembly 33. The relevant size design of the needle seat 31 is conducive to miniaturization of the needle seat 31, thereby making it easier for the operator to observe the treatment area and avoiding repeated treatment of the same treatment area.
[0043] In addition, a slope 313 is formed at the extended end of the connection portion 311 of the needle seat 31, and the slope 313 is inclined to the extension direction of the needle tube group 33. By providing the slope 313 on the connection portion 311, the operator's visual range of the treatment site during operation can be effectively expanded, and the operator is prevented from operating the operating handle 100 to repeatedly treat the same treatment area, thereby ensuring the treatment effect while further reducing the pain caused to the patient during the treatment process, and also reducing the risk of the patient's epidermis being scalded. Among them, the angle a between the slope 313 and the axial direction of the electrode of the electrode group 32 (or the axial direction of the needle tube 331) is preferably between 30° and 50°.
[0044] Combination Figure 7 The liquid feeding unit 4 includes a liquid storage tube 41, a liquid feeding rod 42 and a driving mechanism 43. In this embodiment, the first end of the liquid storage tube 41 is provided with the above-mentioned liquid outlet 411 and the plug hole 412; wherein, the front end of the housing 1 is provided with a mounting hole, and the first end of the liquid storage tube 41 is installed in the mounting hole, that is, the plug hole 412 is located in the mounting hole, and the liquid outlet 411 is located in the plug hole 412; the liquid storage tube 41 has a liquid storage cavity 413, and the liquid storage cavity 413 is used to store the nutrient solution to be injected, and the opening of the liquid storage cavity 413 is formed at the second end of the liquid storage tube 41. In addition, an electrical connection part is provided in the plug hole 412, and the electrical connection part is electrically connected to the control unit 2, and the needle 3 is detachably connected to the plug hole 412 through the mounting part 312 of the needle seat 31. Preferably, the first end of the liquid storage tube 41 is formed with a liquid outlet tube in the plug hole 412, and the liquid outlet 411 is formed on the liquid outlet tube, and when the needle seat 31 of the needle 3 is docked with the plug hole 412, the liquid outlet tube is inserted into the flow channel 310 of the needle seat 31, so that the flow channel 310 is better connected with the liquid outlet 411, and the sealing of the connection between the needle 3 and the plug hole 412 is ensured. Further, a first fool-proof structure is provided on the mounting portion 312 of the needle seat 31, and a second fool-proof structure is provided in the plug hole 412. When the mounting portion 312 is inserted into the plug hole 412, the first fool-proof structure and the second fool-proof structure cooperate. This design can prevent the needle 3 from being incorrectly assembled with the plug hole 412, thereby enabling the electrode group 32 to be accurately docked with the electrical connection portion in the plug hole 412.
[0045] When the needle 3 is installed in the socket 412, the flow channel 310 of the needle seat 31 is connected and docked with the liquid outlet 411, and the electrodes of the electrode group 32 are electrically connected to the electrical connection part, so that the control unit 2 can control the electrode group 32 to emit radio frequency waves according to the preset operation. It should be noted that, as another optional solution, the socket 412 can also be formed at the front end of the shell 1, and the liquid outlet 411 of the liquid storage tank is extended into the socket 412, so that when the needle 3 is installed in the socket 412, the flow channel 310 of the needle seat 31 can still be connected with the liquid outlet 411 of the liquid storage tube 41. By designing the needle 3 to be detachable relative to the liquid feeding unit 4 or the shell 1, the needle 3 is replaceable to ensure the safety and hygiene of the operating handle 100 when in use, and to prevent the problem of cross infection between different patients due to the use of the same needle 3, thereby ensuring the safety of the patients.
[0046] Among them, the needle tube group 33 includes more than two needle tubes 331, and the more than two needle tubes 331 are distributed along the width direction of the connecting portion 311 of the needle seat 31; the electrode group 32 includes a positive electrode 321 and a negative electrode 322, and the positive electrode 321 and the negative electrode 322 are distributed along the width direction; in addition, the needle tube group 33 is located between the positive electrode 321 and the negative electrode 322; the first spacing S between two adjacent needle tubes 331 is preferably between 0.65 mm and 0.85 mm, the second spacing between the needle tube 331 and the adjacent positive electrode 321 is preferably between 0.65 mm and 0.85 mm, and the third spacing between the needle tube 331 and the adjacent positive and negative electrodes is preferably between 0.65 mm and 0.85 mm, and the first spacing S, the second spacing and the third spacing are preferably equal. As in the present embodiment, the needle tube group 33 includes two needle tubes 331, and the electrode group 32 includes one positive electrode 321 and one negative electrode 322. By designing the layout of the needle tube group 33 and the electrode group 32, each needle tube 331 and each electrode can maintain synchronization and depth of entering the epidermis, thereby ensuring the treatment effect. Furthermore, the peripheral wall of the positive electrode 321 is preferably coated with an insulating layer, and the peripheral wall of the negative electrode 322 is preferably coated with an insulating layer, so that the discharge points of the positive electrode 321 and the negative electrode 322 are both subcutaneous, avoiding the positive electrode 321 and the negative electrode 322 from scalding the epidermis.
[0047] The liquid feeding rod 42 includes a piston 421 and a push rod 422. The piston 421 is slidably installed in the liquid storage chamber 413 of the liquid storage tube 41, and the piston 421 is sealed and connected to the cavity wall of the liquid storage chamber 413; the push rod 422 is connected to the piston 421, and the push rod 422 extends through the opening of the liquid storage chamber 413 to the outside of the liquid outlet chamber to connect with the driving mechanism 43, so that the driving mechanism 43 can drive the push rod 422 and its piston 421 to slide along the depth direction of the liquid storage chamber 413; wherein, the push rod 422 is parallel to the depth direction of the liquid storage chamber 413.
[0048] In this embodiment, the push rod 422 is rotatably connected to the piston 421 around its own axis, and the push rod 422 is provided with an external thread; the driving mechanism 43 includes a motor 431 and a reducer 432, the motor 431 shaft of the motor 431 is connected to the input shaft of the reducer 432, the output shaft 4321 of the reducer 432 has an internal thread, and the output shaft 4321 is sleeved on the push rod 422, so that the internal thread on the output shaft 4321 is threadedly connected to the external thread of the push rod 422, so that the driving mechanism 43 can drive the push rod 422 to feed slowly through the reducer 432. It can be seen that through the design of the driving mechanism 43, the driving mechanism 43 can drive the liquid feeding rod 42 to move smoothly toward the liquid outlet 411 of the liquid storage tube 41, so as to ensure that the amount of nutrient solution injected by the liquid feeding unit 4 in a single injection can be kept consistent or within the set range, which not only ensures the treatment effect, but also ensures the safety and rationality of the treatment; at the same time, it can also avoid excessive vibration when the driving mechanism 43 drives the liquid feeding rod 42 to move, thereby improving the experience of the patient and reducing the pain of the patient.
[0049] It should be noted that, as another optional scheme, in other embodiments, the piston 421 and the push rod 422 can be fixedly connected, and a dial can be provided on the end of the push rod 422 away from the piston 421; accordingly, the driving mechanism 43 is designed as a linear module, and a claw is provided on the slide of the linear module so that the claw and the dial are engaged and connected, so that the driving structure can push the liquid feeding rod 42 to move toward the liquid outlet 411 of the liquid storage tube 41 through the claw and the dial to realize the injection of nutrient solution.
[0050] In addition, a control module is preferably installed on the shell 1, and the control module may be a physical button, a touch button, etc. The control module is electrically connected to the control unit 2; preferably, when the operating handle 100 is in a held state, the control module is located at the operator's finger, so that the operator can quickly and conveniently control the radio frequency waves emitted by the electrode group 32 and / or control the liquid feeding unit 4 to inject nutrient solution.
[0051] In summary, the operating handle 100 provided by the utility model designs the electrode of the electrode group 32 into a needle shape so that the electrode can enter the epidermis to a certain depth, thereby causing the radio frequency to generate radio frequency waves at a specific depth under the skin, acting on the water molecules in the collagen, causing the bipolar water molecules to vibrate and rotate at a high speed, generating heat by friction, and thus achieving the effect of heating the dermal collagen. Since the electrode enters under the epidermis instead of directly acting on the epidermis, the risk of epidermal burns can be reduced, and the stimulation cycle can be shortened to improve the effect. In addition, by providing the liquid feeding unit 4 and the needle tube group 33, when the electrode group 32 emits radio frequency waves to the skin, nutrient solution can be injected into the skin through the liquid feeding unit 4 and the needle tube group 33 simultaneously to improve the skin's absorption effect of the nutrient solution. At the same time, when the injected nutrient solution contains anesthetic components (such as sodium hyaluronate containing anesthetics on the market), the anesthetic components in the nutrient solution can also relieve the pain during the radio frequency treatment and when the electrode group 32 punctures the skin, thereby improving the user experience.
[0052] Radio frequency instrument embodiment
[0053] Reference Figure 8 The radio frequency instrument 5 includes a power supply device 51 and an operating handle 52 described in the above operating handle embodiment, and the power supply device 51 is electrically connected to the control unit. The radio frequency instrument 5 is provided with the above operating handle 52 so that it will not burn the skin of the patient when in use, and can realize that when the electrode group emits radio frequency waves to the skin, the nutrient solution is injected into the skin through the liquid feeding unit and the needle tube group synchronously, thereby improving the skin's absorption effect of the nutrient solution; and when the injected nutrient solution contains an anesthetic component (such as sodium hyaluronate containing anesthetics on the market), the anesthetic component in the nutrient solution can also alleviate the pain during the radio frequency treatment process and when the electrode group punctures the skin, thereby improving the user experience.

For those skilled in the art, the present invention may have various changes and modifications.
