Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a plasma skin introduction treatment device and a control method. Background Art

[0002] Skin introduction therapy is a treatment method that introduces drugs or nutrients into the skin to achieve skin treatment effects, thereby improving skin quality and enhancing skin gloss and softness. Traditional skin introduction therapy methods usually use microneedles, electroporation or chemical transdermal techniques to form perforations in the skin to introduce drugs or nutrients into the skin. However, these methods may cause skin trauma, pain to the patient or low introduction efficiency.

[0003] At present, the instruments used for skin introduction treatment in the field of medical cosmetology generally use fractional radio frequency, fractional laser, or single-point plasma to form perforations on the skin. However, these methods all have some shortcomings. Among them, the energy of fractional radio frequency is mainly concentrated on the epidermis of the patient, and the energy is relatively low. It cannot reach the dermis and cannot treat more serious wrinkles and scars. Fractional laser is a laser product, which poses a greater risk to both the therapist and the operator. Single-point plasma generally uses a lower frequency current excitation, and the plasma column has poor directivity and low power. The energy size is difficult to control, the consistency is poor, and the treatment speed is relatively slow. Summary of the invention

[0071] Example

[0072] refer to Figures 1 to 9 The embodiment of the present invention provides a plasma skin introduction treatment device 100, which includes a treatment needle 1, a first conductor 2, a fluid supplier 3, a nozzle 4, and a controller 5, wherein:

[0073] The treatment needle 1 is used to generate a plasma column. When the plasma column contacts the skin of the patient, the area toward which the plasma column is directed can form a perforation on the skin of the patient. The surface where the plasma column forms the perforation is the treatment surface 200.

[0074] The first conductor 2 is used to obtain external electrical energy; and the first conductor 2 is configured to be able to turn on and off the treatment needle 1, so that the treatment needle 1 generates or does not generate a plasma column;

[0075] The fluid supplier 3 is used to transport fluid, and the fluid supplier 3 can be a device for transporting liquid such as a liquid pump or a peristaltic pump; the nozzle 4 is arranged beside the treatment needle 1 and is connected to the fluid supplier 3 to spray the fluid transported by the fluid supplier 3 to the treatment surface 200.

[0076] It is understandable that when the treatment needle 1 is turned on, a plasma column can be generated at the front end of the treatment needle 1 to form a perforation on the skin of the patient. Plasma is the fourth state of matter different from solid, liquid and gas. The plasma column generated by the treatment needle 1 is an ionized substance with a columnar structure. The surface where the plasma column forms the perforation is the treatment surface 200. At this time, the treatment surface 200 is also the area to be treated of the patient.

[0077] The first conductor 2 is connected to an external power source to obtain external electrical energy. Therefore, when the first conductor 2 is connected to the treatment needle 1, the first conductor 2 can transmit electrical energy to the treatment needle 1, so that the treatment needle 1 is in a conductive state, so that the treatment needle 1 generates a plasma column, and performs perforation treatment on the treatment surface 200 toward which the treatment needle 1 is facing. After the first conductor 2 is disconnected from the treatment needle 1, the treatment needle 1 is in a non-conductive state, and the treatment needle 1 does not generate plasma. By controlling the conduction or disconnection of the first conductor 2 and the treatment needle 1, the plasma skin introduction treatment device 100 can realize the control of the excitation state of the treatment needle 1.

[0078] In this embodiment, the controller 5 is at least used to control the execution of the actions of the fluid supplier 3 and the nozzle 4. As an example of the present invention, the controller 5 may be an MCU control board, and the controller 5 is configured as follows:

[0079] When it is determined that the treatment needle 1 has finished generating the plasma column, the fluid supplier 3 is turned on to allow the fluid supplier 3 to deliver the fluid to the nozzle 4 , and the nozzle 4 sprays the fluid delivered by the fluid supplier 3 onto the treatment surface 200 .

[0080] It is understandable that when the treatment needle 1 is turned on, the treatment needle 1 will generate a plasma column, thereby forming a tiny perforation on the skin of the person being treated. Therefore, when the treatment needle 1 is turned on, the skin layer opposite to the treatment needle 1 is the treatment surface 200. After that, the treatment needle 1 is disconnected from the first conductor 2, which can be regarded as the treatment needle 1 ending the generation of the plasma column. At this time, the treatment needle 1 can leave the treatment surface 200 or keep not generating the plasma column, so that there is no plasma column in the area where the treatment surface 200 is located. In addition, the controller 5 can also control the conduction between the treatment needle 1 and the first conductor 2 by receiving a specified signal or losing a specified signal, and then determine whether the treatment needle 1 ends generating the plasma column. The specified signal can be a trigger signal set based on the time when the treatment needle 1 has excited the plasma column or based on the time when the treatment needle 1 stays at the current position, etc., and is set according to the use requirements of the plasma skin introduction treatment device.

[0081] After treatment by the treatment needle 1, tiny perforations will be formed in the area where the treatment surface 200 is located. Therefore, after the treatment needle 1 finishes generating the plasma column, the controller 5 turns on the fluid supplier 3, and the fluid delivered by the fluid supplier 3 is sprayed through the nozzle 4 to the area where the perforations are located, so that the fluid sprayed by the nozzle 4 can be introduced into the interior of the skin through the perforations formed by the plasma column.

[0082] The fluid delivered by the fluid supplier 3 may be liquid medicine, nutrients, active substances, etc. Under the control of the controller 5, the liquid medicine, nutrients or active substances are delivered to the nozzle 4 through the fluid supplier 3, and are sprayed to the treatment surface 200 through the nozzle 4, so that the liquid medicine, nutrients or active substances fall into the area where the perforations are located, and are introduced into the interior of the skin through the perforations formed by the plasma column.

[0083] refer to Figure 4 , Figure 5 In some embodiments, the first conductor 2 is configured to be able to rotate in a circumferential direction, and the plasma skin introduction treatment device 100 also includes a conductive contact 9a, which is disposed on the rotation path of the first conductor 2, and when the first conductor 2 rotates to be connected to the conductive contact 9a, the treatment needle 1 is connected to the first conductor 2, and the treatment needle 1 excites the plasma column; when the first conductor 2 rotates to be disconnected from the conductive contact 9a, the treatment needle 1 is disconnected from the first conductor 2, and the treatment needle 1 does not excite the plasma column.

[0084] By setting the first conductor 2 to be rotatable in a circumferential direction, the connection between the first conductor 2 and the conductive contact 9a can be changed into a periodic connection, so that the first conductor 2 and the treatment needle 1 are periodically connected, and the first conductor 2 and the treatment needle 1 are prevented from being connected at a single point for a long time. Moreover, the conductive contact is arranged on the rotation path of the first conductor 2, so that the first conductor 2 can be moved to realize the connection control of the first conductor 2 and the conductive contact, so that the operator can control the timing and position of the treatment needle 1 to excite the plasma column.

[0085] refer to Figure 1-Figure 6 In some embodiments, the plasma skin introduction treatment device 100 further includes a driving motor 7, and the output end of the driving motor 7 is connected to a turntable 8. The turntable 8 is provided with an access terminal 8a, and the access terminal 8a is located at the rotation center of the turntable 8; and the first conductor 2 is provided on the turntable 8 and electrically connected to the access terminal 8a, and the first conductor 2 deviates from the rotation center of the turntable 8.

[0086] By driving the turntable 8 to rotate by the driving motor 7, the first conductor 2 can rotate relative to the rotation center of the turntable 8 with the distance between itself and the rotation center of the turntable 8 as the radius, thereby realizing the periodic rotation of the first conductor 2. The first conductor 2 and the access terminal 8a can be electrically connected through a microstrip line, and the microstrip line is attached to the end surface of the turntable 8. In this way, when the first conductor 2 rotates relative to the rotation center of the turntable 8, the first conductor 2 can maintain communication with the access terminal 8a.

[0087] refer to Figure 1-Figure 5In some embodiments, the plasma skin introduction treatment device 100 further includes a code disk 9, which is connected to the turntable 8 and is used to install a conductive contact 9a; and a central contact 9b is provided in the middle of the code disk 9 to connect to an external power source. The central contact 9b is connected to the access terminal 8a, so that the electric energy introduced from the external power source can be conducted to the access terminal 8a.

[0088] There are multiple conductive contacts 9a, which are fixedly mounted on the code disk 9 around the rotation center of the turntable 8 and arranged on the rotation path of the first conductor 2. Moreover, there are multiple treatment needles 1, which are arranged along the first direction, and the treatment needles 1 are connected one-to-one with the conductive contacts 9a through wires.

[0089] When the driving motor 7 drives the turntable 8 to rotate, the first conductor 2 can rotate relative to the access terminal 8a, and each conductive contact 9a arranged on the rotation path of the first conductor 2 will rotate with the first conductor 2, and be connected and conducted with the first conductor 2 in turn. In this way, each treatment needle 1 connected to the conductive contact 9a one by one can be connected and conducted with the first conductor 2 in turn, so that multiple treatment needles 1 can be triggered cyclically, and multiple treatment needles 1 arranged along the first direction can make the plasma column be cyclically excited in turn along the first direction in the treatment surface 200.

[0090] When the driving motor 7 causes the first conductor 2 to rotate at a constant speed and the conductive contacts 9a are evenly distributed around the rotation center of the turntable 8, the time interval for each treatment needle 1 to take effect can be kept consistent during the treatment process, thereby ensuring the consistency of the treatment intensity and the treatment effect achieved based on the plasma column generated by the treatment needle 1 during the treatment process.

[0091] During the rotation of the first conductor 2, the conduction between the first conductor 2 and the conductive contact 9a is periodic. When the first conductor 2 and the conductive contact 9a are not connected, if the first conductor 2 keeps discharging, arcing will occur, which will affect the service life of the conductive contact 9a. Therefore, in some embodiments, the controller 5 is further configured as follows:

[0092] When the first conductor 2 is in contact with the conductive contact 9a, the first conductor 2 is discharged and conducts electricity between the first conductor 2 and the conductive contact 9a; when the first conductor 2 is not in contact with the conductive contact 9a, the first conductor 2 is not discharged.

[0093] It can be understood that when the first conductor 2 is connected to the conductive contact 9a, the controller 5 generates a discharge signal to connect the first conductor 2 to the external power supply, thereby discharging the first conductor 2, and when the first conductor 2 is not connected to the conductive contact 9a, the controller 5 does not generate a discharge signal. At this time, the first conductor 2 is not connected to the external power supply, and the first conductor 2 does not discharge. In this way, the controller 5 can control the execution of the discharge action of the first conductor 2 based on the connection between the first conductor 2 and the conductive contact 9a, and avoid the phenomenon of arcing when the first conductor 2 and the conductive contact 9a are not connected.

[0094] refer to Figure 1-Figure 6 In some embodiments, the plasma skin introduction treatment device 100 further includes a second conductor 6, which is electrically connected to the treatment needle 1, and the second conductor 6 is connected to the conductive contact 9a, so that when the first conductor 2 is rotated to be connected to the conductive contact 9a, the treatment needle 1, the second conductor 6, and the first conductor 2 are electrically connected.

[0095] The second conductor 6 may be a conductive spring needle, so that the second conductor 6 can be close to the treatment needle 1 and connected to the treatment needle 1. The number of the second conductors 6 corresponds to the number of the treatment needles 1. When there are multiple treatment needles 1, the number of the second conductors 6 is also multiple. The multiple second conductors 6 are arranged along the first direction and connected to the treatment needles 1 in a one-to-one correspondence.

[0096] The driving motor 7 drives the turntable 8 to rotate, and the first conductor 2 on the turntable 8 is connected to each conductive contact 9a in turn, so that the central contact 9b on the code disk 9 and the multiple conductive contacts 9a are connected in turn. In this way, the conductive contacts 9a on the code disk 9 are connected to the second conductors 6 one by one, and the central contact 9b is connected to the external power supply. The external electric energy is sequentially transmitted to the treatment needle 1 through the second conductor 6. The treatment needle 1 generates a plasma column, which acts on the human skin to achieve the effect of treatment. Moreover, the multiple treatment needles 1 are designed in an array along the first direction, so that the plasma skin introduction treatment device 100 can achieve multi-point plasma treatment, improve the treatment speed, and ensure the consistency and uniformity of the treatment effect.

[0097] refer to Figure 1-Figure 8 In some embodiments, the plasma skin introduction treatment device 100 further includes a treatment head holder 10 and a treatment head 11, wherein:

[0098] The treatment head base 10 is used to install the second conductor 6. A plurality of second conductors 6 are arranged on the treatment head base 10 along a first direction. Figure 1 The treatment head base 10 is shown in its length direction; the treatment head 11 is connected to the treatment head base 10 and is used to install the treatment needle 1 and the nozzle 4.

[0099] The treatment head base 10 has a first fluid channel 10a for receiving the fluid delivered by the fluid supplier 3. The first fluid channel 10a has a fluid outlet 100a, and the fluid outlet 100a is arranged at the end of the first fluid channel 10a and located at the end surface where the second conductor 6 is located, and the direction of the fluid outlet 100a is the same as the extension direction of the second conductor 6.

[0100] The treatment head 11 has a second fluid channel 11a extending along the first direction, and the nozzle 4 is installed on the treatment head 11 so that the second fluid channel 11a is connected with the fluid outlet 100a and the nozzle 4, so that the fluid discharged from the fluid outlet 100a is delivered to the nozzle 4.

[0101] It can be understood that, while the treatment head seat 10 provides protection for the second conductor 6, it can set a first fluid channel 10a and limit the position of the fluid outlet 100a, so that the fluid delivered by the fluid supplier 3 flows to the end surface where the second conductor 6 is located through the fluid outlet 100a, and then, through the second fluid channel 11a set in the treatment head 11, the fluid delivered by the fluid supplier 3 flows to the nozzle 4, thereby realizing fluid delivery.

[0102] refer to Figure 2 In some embodiments, the nozzle 4 is provided with a plurality of nozzle holes 4a, and the plurality of nozzle holes 4a are arranged along a first direction, and the nozzle holes 4a are arranged toward the treatment surface 200 to ensure that the medicine, nutrients, active substances, etc. delivered by the fluid supplier 3 can be sprayed to the end surface corresponding to the plasma excited by the treatment needle 1, that is, the treatment surface 200. In this way, after the treatment needle 1 excites plasma and perforates the skin layer where the treatment surface 200 is located, the medicine, nutrients, and active substances can reach the perforations and be introduced into the skin through the perforations formed by the plasma.

[0103] refer to Figure 1 , Figure 2In some embodiments, the nozzle 4 is mounted on the treatment head 11, and the nozzle hole 4a and the treatment needle 1 are arranged on the same end face of the treatment head 11. On the end face, the direction perpendicular to the first direction is defined as the second direction, and the nozzle hole 4a is located beside the treatment needle 1. The nozzle hole 4a and the treatment needle 1 are arranged in parallel with each other and the nozzle hole 4a and the treatment needle 1 are arranged in sequence in the second direction to seal the second fluid channel 11a, and the nozzle hole 4a can be directed to the treatment surface 200 at the same time as the treatment needle 1, so that after the treatment needle 1 excites the plasma column and leaves the current position, the nozzle hole 4a comes to the previous position of the treatment needle 1, and the position of each nozzle hole 4a can directly correspond to the perforation position formed by the treatment needle 1, so that the fluid ejected through the nozzle hole 4a can directly reach the perforation formed by the plasma column. Moreover, after the nozzle 4 seals the second fluid channel 11a, the liquid medicine, nutrients, and active substances flowing in the second fluid channel 11a can be kept clean, and before being ejected by the nozzle 4, the fluid transported by the fluid supplier 3 can flow in a relatively sealed environment to avoid contamination by external impurities.

[0104] As an example of the present invention, the nozzle 4 can be a piezoelectric nozzle. The mist liquid sprayed by the nozzle 4 has a small particle size, which is suitable for the perforations formed by plasma liquid medicine, nutrients, and active substances, so that after the liquid medicine, nutrients, and active substances are sprayed by the nozzle 4, their particle size is suitable for introduction into the perforations formed by the plasma column. Specifically, a piezoelectric contact can be provided on the treatment head seat 10, and the piezoelectric contact is connected to the controller 5. After the treatment head 11 is installed on the treatment head seat 10, the piezoelectric contact can be connected to the nozzle 4, so that the controller 5 can control the action of the nozzle 4.

[0105] It should be noted that the nozzles of piezoelectric nozzles are generally micro-holes with very small apertures. Figure 1 The spray hole 4a shown is a schematic diagram for explaining the location of the spray hole 4a of the spray head 4 in this embodiment, and does not limit the aperture of the spray hole 4a.

[0106] In addition, as an example of the present invention, the piezoelectric contact can adopt elastic contact, so that when the treatment head 11 is installed on the treatment head base 10, the treatment head 11 and the treatment head base 10 can be connected more tightly, and the piezoelectric contact will not affect the tightness of the connection between the treatment head 11 and the treatment head base 10. Moreover, the treatment head 11 is tightly connected to the treatment head base 10, which can ensure that the piezoelectric contact is tightly connected to the nozzle 4, thereby ensuring that the controller 5 can smoothly execute the action control of the nozzle 4.

[0107] refer to Figure 1 , Figure 2 , Fig. 9In some embodiments, the plasma skin introduction treatment device 100 further includes a sensing switch 12, which is configured to periodically trigger an on signal and transmit the on signal to the controller 5; at this time, the controller 5 is also used to control the action of the treatment needle 1, and the controller 5 is further configured to:

[0108] When receiving the connection signal, the first conductor 2 is connected to the treatment needle 1, so that the treatment needle 1 generates a plasma column;

[0109] When the connection signal is lost, the first conductor 2 is disconnected from the treatment needle 1, so that the treatment needle 1 stops generating the plasma column;

[0110] After the connection signal is lost, when the connection signal is received again, the first conductor 2 and the treatment needle 1 are connected again, so that the treatment needle 1 generates a plasma column, and the fluid supplier 3 is turned on to transport the fluid to the nozzle 4, and the nozzle 4 sprays the fluid transported by the fluid supplier 3 onto the treatment surface 200.

[0111] It is understandable that the induction switch 12 periodically triggers the on signal, so that the controller 5 can make the treatment needle 1 periodically generate a plasma column based on the on signal. After the treatment needle 1 generates a plasma column in the current round, the treatment needle 1 will form a perforation on the end face currently facing, thereby forming a first treatment surface 200 in the area to be treated by the patient. As the induction switch 12 periodically triggers the on signal, the treatment needle 1 ends generating the plasma column in the current round, and during the next round of conduction with the first conductor 2, the operator can move the treatment needle 1 to the next area, so that the treatment needle 1 leaves the first treatment surface 200. Based on the nozzle 4 being arranged beside the treatment needle 1, by controlling the movement direction of the treatment needle 1, the nozzle 4 can enter the first treatment surface 200 after the treatment needle 1 leaves the first treatment surface 200. When the connection signal is received again, the treatment needle 1 generates a plasma column in the next area to form a second treatment surface 200, and the fluid supplier 3 and the nozzle 4 spray fluid to the first treatment surface 200 after being pierced by the treatment needle 1. In this way, the action of the treatment needle 1 to stimulate the plasma column and the action of the nozzle 4 to spray the fluid are cyclically stimulated, so that the plasma skin introduction treatment device 100 can cyclically perform skin introduction treatment.

[0112] It should be noted that the generation of the contact signal is periodic. Therefore, when the plasma skin introduction treatment device 100 starts treatment, there may be a state where the connection signal is interrupted as the starting point of the treatment action. At this time, since the plasma column of the treatment needle 1 has not been excited and the skin of the treated person has not been pierced, the controller 5 may not control the fluid supplier 3 to deliver fluid.

[0113] It is understandable that the controller 5 can control the action of the first conductor 2 by means of an electric control switch, a contact signal, etc. By periodically triggering the on signal by the induction switch 12, the plasma skin introduction treatment device 100 can periodically excite the plasma column and periodically eject the fluid. By converting the triggering condition of the periodic triggering of the on signal by the induction switch 12 into the moving distance of the treatment needle 1, the plasma skin introduction treatment device 100 can realize the fixed-distance cyclic excitation of the skin introduction treatment.

[0114] refer to Figure 1 , Figure 2 , a roller member 13 is provided on the treatment head 11 or the treatment head seat 10, and the roller member 13 can move on the skin, so that the treatment needle 1 moves on the skin, and the roller member 13 rolls in the second direction. As an example of the present invention, in this embodiment, the roller member 13 is connected to the treatment head seat 10, and the operator pushes the plasma skin introduction treatment device 100, so that the roller member 13 can drive the treatment head 11 and the treatment head seat 10 to move on the skin of the treated person.

[0115] Furthermore, the induction switch 12 is configured to include an induction magnet block 12a and an induction trigger block 12b, wherein:

[0116] The induction magnet block 12a is used to generate a magnetic field, and the induction magnet block 12a is disposed on the roller member 13 to perform periodic rotation along with the roller member 13;

[0117] The induction trigger block 12b is connected to the controller 5, and the induction trigger block 12b has an induction contact 120b, and the induction contact 120b is arranged on the rotation path of the induction magnet block 12a; and the induction trigger block 12b is arranged as follows:

[0118] When the sensing magnet block 12 a rotates to the position where the sensing contact 120 b is located, the sensing trigger block 12 b triggers a connection signal and transmits the connection signal to the controller 5 .

[0119] It can be understood that the induction magnet block 12a is arranged on the inner end surface or the outer end surface of the roller member 13 and deviates from the rotation center of the roller member 13. In this way, when the roller member 13 rotates, the induction magnet block 12a can rotate therewith, and when the roller member 13 rotates multiple times, the induction magnet block 12a will rotate therewith to achieve periodic rotation.

[0120] By the periodic rotation of the induction magnet block 12a with the roller member 13, the induction magnet block 12a will cyclically trigger the connection signal with the induction trigger block 12b. For example, if the rotation path of the induction magnet block 12a is a circle, the induction electric shock is arranged at any point of the circle. When the roller member 13 moves on the skin of the treated person, the distance traveled by the roller member 13 will be equivalent to the distance rotated by the induction magnet block 12a on the circle. In this way, when the roller member 13 moves one circle, the induction magnet block 12a will also move one circle on the circular path, and mutually induce with the induction trigger block 12b to trigger the connection signal, so that the controller 5 receives the connection signal, so that the first conductor 2 is connected to the treatment needle 1, and the treatment needle 1 generates a plasma column.

[0121] Therefore, after a rolling member is provided on the treatment head seat 10 and an induction magnet block 12a is configured on the rolling member, the triggering condition for the induction switch 12 to periodically trigger the connection signal is the number of revolutions of the rolling member, which is equivalent to the distance traveled by the rolling member on the skin of the patient, and is also equivalent to the distance traveled by the treatment head 11, the treatment head seat 10, or the treatment needle 1 on the skin of the patient, so that the plasma skin introduction treatment device 100 can cyclically excite plasma columns at a fixed distance, and by changing the diameter of the roller member 13, the number of induction magnet blocks 12a, and the number of induction electric shocks, the plasma skin introduction treatment device 100 can change the spacing of the cyclically excited plasma columns to adapt to different treatment environments.

[0122] It should be noted that after receiving the connection signal, based on the relative position between the first conductor 2 and the conductive contact 9a, the controller 5 may be in a position where the first conductor 2 is not connected to the conductive contact 9a. Therefore, the controller 5 can also be configured to control the operation of the drive motor 7, so that the drive motor 7 drives the first conductor 2 to rotate until it is connected to the conductive contact 9a, so that the first conductor 2 is conductive to the treatment needle 1.

[0123] refer to Figure 1 As an example of the present invention, there are four induction magnet blocks 12a arranged on the roller member 13, and the four induction magnet blocks 12a are evenly arranged around the rotation axis of the roller member 13, so that the induction trigger block 12b can periodically trigger the connection signal as the roller member 13 rotates a quarter of a turn.

[0124] Based on the aforementioned plasma skin introduction treatment device 100, this embodiment further provides a control method of the plasma skin introduction treatment device 100, which is applicable to the aforementioned plasma skin introduction treatment device 100. The control method includes:

[0125] When the first conductor 2 is electrically connected to the treatment needle 1, the treatment needle 1 generates a plasma column toward the treatment surface 200;

[0126] When the treatment needle 1 stops generating the plasma column and there is no plasma column on the treatment surface 200 , the fluid supplier 3 delivers the fluid to the nozzle 4 , and the nozzle 4 sprays the fluid delivered by the fluid supplier 3 onto the current treatment surface 200 .

[0127] Based on the aforementioned control method, when the plasma skin introduction treatment device 100 performs skin introduction treatment, the treatment head 11 can be first aligned with the treatment area to be treated, and then the roller 13 can be rolled to rotate the induction magnet block 12a to the position of the induction trigger block 12b, so that the induction magnet block 12a and the induction trigger block 12b are mutually inductively sensed, triggering a connection signal, so that the controller 5 receives the connection signal.

[0128] After the controller 5 receives the connection signal, the controller 5 determines whether the first conductor 2 is connected to the conductive contact 9a:

[0129] If the first conductor 2 is connected to the conductive contact 9a, the controller 5 sends a discharge signal to discharge the first conductor 2, thereby achieving conduction between the first conductor 2 and the treatment needle 1;

[0130] If the first conductor 2 is not connected to the conductive contact 9a, the controller 5 activates the drive motor 7 to drive the first conductor 2 to rotate until it is connected to the conductive contact 9a, and then sends a discharge signal to discharge the first conductor 2, thereby achieving conduction between the first conductor 2 and the treatment needle 1.

[0131] After the first conductor 2 is connected to the treatment needle 1, the corresponding treatment needle 1 will excite a plasma column, thereby forming a tiny perforation on the treatment surface 200 facing the treatment needle 1, and within a single connection signal cycle, the controller 5 can drive the drive motor 7 to cyclically operate, so that the first conductor 2 is connected to any conductive contact 9a for a period of time, and then rotates to the next position, and connects to the next adjacent conductive contact 9a, so that the treatment needles 1 arranged along the first direction cyclically excite plasma columns, so that the treatment needle 1 array excites plasma columns within a single connection signal cycle.

[0132] After the plasma column generated by the treatment needle 1 forms sufficient perforations on the treatment surface 200, the operator can push the plasma skin introduction treatment device 100, and the roller member 13 rolls in the second direction, so that the treatment head seat 10 drives the treatment needle 1 to leave the treatment surface 200 from the second direction and move to the next position. At this time, the nozzle 4 will move to the treatment surface 200, that is, the treatment surface 200 previously perforated by the plasma column.

[0133] As the roller 13 rotates, the induction magnet block 12a previously in the trigger position will leave the induction position with the induction trigger block 12b, the induction device loses the connection signal, and the treatment needle 1 does not excite the plasma column. The controller 5 then controls the fluid supplier 3 to deliver the liquid medicine, nutrients, and active substances to the nozzle 4. The controller 5 cooperates with the fluid supplier 3 to control the delivery amount of the fluid, and controls the piezoelectric contact through the controller 5, so that the nozzle 4 can accurately control the amount of fluid introduced, so that the mist liquid sprayed by the nozzle 4 can be appropriately introduced into the perforation formed by the plasma column.

[0134] In summary, the embodiment of the present invention provides a plasma skin introduction treatment device 100, which can generate tiny perforations in the skin of the treated person through the plasma generated by the treatment needle 1, and control the actions of the fluid supplier 3 and the nozzle 4 through the controller 5, so that the fluid supplier 3 delivers the fluid to the nozzle 4 for spraying after the treatment needle 1 performs plasma perforation treatment, so that the medicine or nutrients can be sprayed to the treatment surface 200 perforated by the treatment needle 1, ensuring that the active ingredients of the medicine or nutrients can penetrate deeply into the skin and improve the absorption efficiency of the active ingredients; moreover, compared with the traditional perforation introduction method of microneedles or electroporation, the plasma skin introduction treatment device 100 uses the first conductor 2 and the treatment needle 1 to generate plasma, which can reduce the trauma of the skin tissue of the treated person and the pain of the treated person during treatment, thereby improving the convenience and acceptability of skin introduction treatment.

[0135] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
