Description

Technical Field

[0001] The invention belongs to the field of ear canal treatment and relates to a real-time observation type plasma ear canal treatment instrument and a use method. Background Art

[0002] While widely used, traditional treatments for external auditory canal diseases have several significant drawbacks. First, drug therapy faces the challenge of poor drug penetration, particularly for deep-lying infections. Topical medications struggle to maintain adequate drug concentrations, while systemic medications can cause unwanted side effects. Second, prolonged or frequent use of antibiotics can lead to the emergence of drug-resistant bacteria, complicating subsequent treatment. While necessary, ear canal cleaning can cause discomfort and, if performed improperly, can lead to damage to the external auditory canal skin or perforation of the tympanic membrane. For chronic or recurring conditions, repeated cleaning and medication use can reduce patient compliance. While surgical intervention can address some persistent problems, it is invasive and can lead to complications such as infection, bleeding, or hearing loss, increasing medical costs and recovery time. Furthermore, traditional treatments often employ a one-size-fits-all approach, making it difficult to tailor treatment to individual differences and the specific characteristics of specific pathogens. Their effectiveness is particularly limited when treating biofilm-associated infections. Finally, these approaches are inadequate in preventing recurrence, as they struggle to fundamentally alter the microenvironment of the external auditory canal.

[0003] Plasma technology has shown tremendous potential and broad prospects for the treatment of external auditory canal diseases. This innovative therapy leverages the unique physical and chemical properties of low-temperature plasma, potentially overcoming many of the limitations of traditional treatments. Plasma produces a variety of active substances, such as free radicals, ions, and ultraviolet light, which possess potent bactericidal properties and can effectively eliminate bacteria, fungi, and viruses, even showing promising results against antibiotic-resistant strains. Its low temperature minimizes the risk of thermal damage to sensitive ear canal tissue during treatment. Furthermore, plasma can penetrate deep and narrow areas of the ear canal, addressing the inaccessibility of traditional topical medications.

[0004] A small plasma device is needed to treat ear canal diseases. However, existing small plasma devices cannot accurately locate the electrode in the ear canal for treatment and cannot accurately monitor the treatment status during discharge, and cannot perform online treatment. Summary of the Invention

[0005] 1. Technical problems to be solved: Existing plasma equipment cannot accurately position the electrodes for treating the ear canal and cannot accurately monitor the discharge. 2. Technical solution: To address the above problems, the present invention provides a real-time observation plasma ear canal treatment instrument, comprising a power drive unit, an electrode unit, a camera light sensor unit, and an integrated screen display and data storage unit, wherein the power drive unit comprises a lithium battery, a voltage regulating and stabilizing module, and an AC module connected in sequence via electrical connection lines.

At this time, the position of the ear canal inflammation lesion can be monitored in real time, and the direction of the camera in the camera light sensor unit can be adjusted by the camera adjustment knob to complete the lesion positioning. After the lesion positioning is completed, the plasma generator button switch is pressed, and the FE-DBD electrode starts to discharge.

[0025] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 and Figure 2 As shown, a real-time observation plasma ear canal treatment instrument includes a power drive unit, an electrode unit, a camera light sensor unit 8, and an integrated screen display and data storage unit. The power drive unit includes a lithium battery, a voltage regulating and stabilizing module, and an AC module connected in sequence via electrical connection lines. The power drive unit supplies the high voltage required for discharge to the electrode unit via electrical connection lines. The camera light sensor unit 8 is fixedly connected to the electrode unit. The integrated screen display and data storage unit is connected to the camera light sensor unit 8 via a data connection line 4. The electrode unit includes a plasma generator. The plasma generator 6 includes a plasma generator housing and an FE-DBD electrode 9. The plasma generator housing 6 is located at the front end of the FE-DBD electrode 9. The dielectric layer of the FE-DBD electrode 9 is quartz glass, and a metal needle is provided in the quartz glass.

[0027] The present invention is primarily used for precise location, real-time monitoring, and efficient sterilization of ear canal inflammation. A plasma ear canal treatment device with an integrated camera and display screen is provided. This device enables precise location and real-time monitoring of ear canal inflammation, thereby improving treatment effectiveness and simplifying the operation process. The device uses plasma discharge to achieve efficient sterilization and anti-inflammatory treatment of target areas within the ear canal, and displays the treatment process in real time on the display screen 1.

[0028] The electrode of this invention is a floating electrode dielectric barrier discharge (FE-DBD) device, an optimized version of the DBD device. FE-DBD replaces the ground electrode in the DBD structure with a larger, floating, ungrounded object to be treated (e.g., the human body). Discharge occurs between the high-voltage electrode and the suspended object.

[0029] During use, the FE-DBD electrode is placed in the ear canal, which acts as a ground electrode. The FE-DBD discharges electricity within the ear canal, effectively sterilizing and reducing inflammation in the target area inside the ear canal. This addresses the limitations of traditional wet-treatment ear canal inflammation treatments, such as infection and drug resistance.

[0030] Therefore, FE-DBD can not only flexibly replace the functions of traditional DBD, but also directly apply the generated plasma to the human body, improving the treatment effect and efficiency.

[0031] In one embodiment, the metal needle in the FE-DBD electrode 9 has a diameter of less than 3 mm, and the treatment electrode head is less than or equal to 10 mm long. This limits the plasma discharge area, thereby limiting the maximum discharge current during the entire ear canal treatment process and ensuring the electrical safety of the plasma treatment in the ear canal.

[0032] In one embodiment, in order to realize the high-voltage electrode inside the FE-DBD electrode 9, a high-voltage metal needle and copper powder are combined to form the high-voltage electrode of the present invention. The injection of copper powder ensures that the high-voltage electric field parameters inside the quartz glass tube remain consistent, does not cause tip discharge problems, and ensures that the length of the treatment electrode head can generate plasma active components with equivalent discharge intensity. At the same time, the high-voltage potential is introduced into the copper powder through the high-voltage metal needle, and the high-voltage metal needle is connected to the high-voltage port of the driving power supply.

[0033] In one embodiment, the camera light sensor unit 8 is mounted on the FE-DBD electrode 9. To address the issue of high-voltage discharge interfering with the sensor's weak electrical insulation, the camera light sensor unit 8 comprises a fixed camera and LED light. The LED light illuminates the lesion during lesion localization, while the camera captures the treatment area in real time during discharge therapy. The camera is metal-wrapped and connected to the power ground. It is also wrapped with multiple layers of insulating tape of varying materials, improving its withstand voltage rating and addressing electromagnetic interference.

[0034] In one embodiment, a plasma generator button switch 5 is also included. The plasma generator button switch 5 is internally grounded. When a person presses the button, the FE-DBD electrode 9 generates a discharge plasma. This design ensures reliable connection between the human body and the ground electrode of the driving power supply, ensuring reliable discharge operation.

[0035] In one embodiment, the integrated screen display and data storage unit includes a display screen 1 and a control unit. The display screen 1 is provided with a display screen operation button 2. By pressing the relevant button of the display screen operation button 2, the LED lights on the display screen 1 and the camera light sensor unit are turned on.

[0036] The display screen 1 is used to display the internal image and processing status of the ear canal in real time. The control unit is connected to the camera light sensor unit 8, the display screen 1 and the FE-DBD electrode 9, and is used to control the generation of plasma and the transmission of images collected by the camera light sensor unit 8.

[0037] In one embodiment, the control unit includes a microprocessor and a memory, which can store image data and operation records during the treatment process and provide a data playback function to facilitate subsequent analysis and diagnosis.

[0038] In one embodiment, a camera adjustment knob 3 is further included for adjusting the angle of the camera light sensor unit 8 . One end of the camera adjustment knob 3 is connected to the camera light sensor unit 8 , and the other end is connected to the display screen 1 .

[0039] In one embodiment, the display screen 1 is a handheld display screen, which allows the user to control operations through the display screen operation buttons 2, including real-time viewing of camera images, positioning and adjusting light sources, and plasma intensity and switch control. In one embodiment, the high-voltage driving power supply and the FE-DBD electrode form an independent handheld operating device, which is separated from the integrated display screen and powered by a lithium battery. The handheld device is more convenient and flexible to handle and is portable.

[0040] In one embodiment, the FE-DBD electrode 9 is provided with an electrode protection sleeve 10, and the protection sleeve 10 is fixedly connected to the plasma generator housing 6. The electrode protection sleeve 10 is used to protect the mechanical safety of the FE-DBD electrode 9.

[0041] The present invention also provides a method for using the real-time observation type plasma ear canal treatment instrument, wherein the electrode protection sleeve 10 is removed, the FE-DBD electrode (9) is placed in the ear canal, and the display screen 1 and the LED light on the camera light sensor unit 8 are turned on by pressing the relevant button of the display screen operation button 2. At this time, the position of the ear canal inflammation lesion can be monitored in real time, and the direction of the camera in the camera light sensor unit 8 can be adjusted by the camera adjustment knob 3 to complete the lesion positioning; after the lesion positioning is completed, the plasma generator button switch 5 is pressed, and the FE-DBD electrode 9 will start to discharge. The relevant button on the display screen operation button 2 is pressed again to turn off the LED light on the camera light sensor unit 8, and the discharge image is observed on the display screen 1 to monitor the treatment situation; the discharge time is flexibly controlled by the plasma generator button switch 5, and the plasma generation intensity is adjusted as needed.

[0042] The experiment of locating the wound surface inside the ear canal was conducted when the camera light was off and when it was on. An ear model was used to simulate the ear canal environment, and a camera light sensor unit was used to capture real-time images of the ear canal. Finally, the integrated screen display and data storage unit was used for real-time monitoring and storage of image data and operation records during the treatment process. A data playback function was also provided to facilitate subsequent analysis and diagnosis. When the light was on, the lesion could be located by illuminating the dark ear canal environment. When the light was off, discharge could be performed and the discharge situation could be monitored in real time. The experiment proved that the wound surface inside the ear canal could be located by the camera light sensor unit and the integrated screen display and data storage unit of the device.

[0043] Experimental verification of the feasibility of plasma discharge inside the ear canal.

[0044] An experimental platform was built to conduct a discharge feasibility experiment. The working waveform of the device was observed through an oscilloscope. Discharge filaments were observed at the rising and falling edges of the waveform, indicating the generation of plasma discharge. The discharge image can be captured by the camera integrated at the electrode end. The image is as follows: Figure 3 As shown, the discharge picture of the display screen is taken by a mobile phone. The discharge image is in the red circle, proving that plasma can discharge in the ear canal.

[0045] The present invention uses a camera integrated in the electrode of the plasma generator head to photograph the inside of the ear canal and display it in real time on the display screen. The lesion can be accurately located before treatment. When the button on the plasma generator pen is pressed, the discharge treatment begins and the discharge treatment lesion status can be monitored in real time through the camera.
