This application proposes an intense pulsed light treatment head for treating cavity tissue.

In the embodiment of the present application, as shown in FIGS. 1 to 5, the intense pulsed light treatment head includes: a light-transmitting tube 10, the wall of the light-transmitting tube 10 is at least partially light-transmissive, and the light-transmitting tube 10 is used for To extend into the cavity tissue; a sterilization light source 20, the sterilization light source 20 is arranged in the light-transmitting tube 10 to irradiate the cavity tissue through the light-transmitting part of the light-transmitting tube 10.

In this embodiment, the light-transmitting tube 10 can emit light completely or partly. It only needs to satisfy that the light of the sterilization light source 20 can irradiate the cavity tissue through the light-transmitting part after the light-transmitting tube 10 extends into the cavity tissue. The light of the sterilization light source 20 has a killing effect on bacteria and pathogens. For example, the spectral wavelength of the sterilization light source 20 can be set to not less than 200 nm and not greater than 1200 nm, so that the wavelength range of the sterilization light source 20 covers a variety of monochromatic lights. , It can kill different kinds of bacteria and pathogens. Specifically, the germicidal light source 20 can be set as a pulsed xenon lamp, which is an electric light source that emits light by using xenon gas, and the pulsed xenon lamp can use stored electrical energy or chemical energy to generate high-intensity flashes in a very short time. The high-intensity flash of the pulsed xenon lamp can effectively kill bacteria and shorten the irradiation time of the germicidal light source 20 in the cavity tissue, so as to reduce the influence of the temperature or light generated by the germicidal light source 20 on the cavity tissue during the illumination process. As a result, the therapeutic effect can be further improved.

In practical applications, in order to improve the therapeutic effect, the optical power density of the sterilization light source 20 can be set to 50mw/cm ² to 500mw/cm ² , preferably 150mw/cm ² to 300mw/cm ² ; in order to adapt to different degrees of disease, sterilization The light source 20 can be set to four gears of 150mw/cm ² , 200mw/cm ² , 250mw/cm ² and 300mw/cm ^2.

The outer peripheral wall of the outer end of the mounting cylinder 30 may be protrudingly provided with a positioning boss extending in the axial direction, and the positioning boss abuts against the open periphery of the light-transmitting tube 10 to limit the insertion depth of the mounting cylinder 30. The specific shape of the fixing member 40 is not limited, and it only needs to be fixedly matched with the mounting barrel 30.

The germicidal light source 20 is set as a lamp tube, which can increase the illumination range. Correspondingly, the wall of the light-transmitting tube 10 is all light-transmissive, so as to cooperate with the germicidal light source 20 arranged in the lamp tube to increase the irradiation area of the cavity tissue, thereby improving the treatment efficiency , Shorten the treatment time. The length of the light-transmitting tube 10 can be set to be 3 cm to 12 cm, and the length of the sterilization light source 20 is adapted to the length of the light-transmitting tube 10. The light-transmitting tube 10 can be made of materials with higher light transmittance, and its inner and outer surfaces are frosted to reduce light reflection on the tube wall, increase the transmitted light and change the spatial distribution of light, so that all parts of the tube wall are illuminated.

The peripheral wall of the sterilization light source 20 protrudes from the two surfaces of the baffle 50, so that when the air flows along the baffle 50, it can directly contact the surface of the sterilization light source 20 to exchange heat, so as to improve the cooling effect. The end of the sterilization light source 20 away from the fixing member 40 can be welded to the baffle 50 to make the fixing structure of the sterilization light source 20 more stable. In addition, the power cord of the sterilization light source 20 can be attached to the surface of the deflector 50 and extend along the surface of the deflector 50 to connect to the end of the sterilization light source 20 away from the fixing member 40, so that the power cord is in the light-transmitting tube The wiring method within 10 is more regular and stable.

Different effects, make it fall off, so as to achieve the purpose of treatment. During the treatment process, by rotating the light-transmitting tube 10, the sterilization light and the heat generated by the radio frequency electrode 60 can alternately act on the same part, so as to further enhance the treatment effect. The radio frequency electrodes 60 can extend in the circumferential direction of the radio frequency zone 12, and the number of radio frequency electrodes 60 can be multiple.

The reflecting surface of the reflecting plate 70 can be a flat surface or a curved surface. For example, the middle of the reflecting surface of the reflecting plate 70 can protrude toward the germicidal light source 20 to form a convex ridge, thereby dividing the reflecting surface into two inclined surfaces forming an angle. As a result, the light can be more uniformly reflected to each part of the light-transmitting area 11.

In practical applications, the central angle of the projection of the light-transmitting area 11 on the cross-section of the light-transmitting tube 10 is not less than 180° and not more than 210°.

At this time, the trigger circuit of the trigger 240 is activated to trigger the pulsed xenon lamp 310 and make the pulsed xenon lamp 310 flash. The trigger circuit is composed of partial resistors, capacitors, and trigger transformers (trigger coils), etc., and is installed on the ignition pole of the pulsed xenon lamp 310. When the switch button of the interaction unit 400 is pressed, the trigger circuit of the pulsed xenon lamp 310 generates a pulsed high voltage through the synchronous contact, so that the xenon gas in the pulsed xenon lamp 310 is ionized into xenon ion conduction. Therefore, a large amount of electric charge stored in the energy storage capacitor 230 is quickly discharged through the pulsed xenon lamp 310 to form a large current, and the electric energy is instantly converted into light energy to emit strong light. Please refer to FIG. 8 for the specific circuit of the external trigger when the switch button of the interaction unit 400 is pressed.

When the pulsed xenon lamp 310 is working, a large amount of heat is generated, which causes the temperature of the pulsed xenon lamp 310 to increase. The above-mentioned refrigeration module 320 can be used to cool the pulse xenon lamp 310. The setting of the light intensity sensor 330 can prevent excessive light from causing harm to the human body, and the setting of the temperature sensor 340 can prevent the human body from being harmed by excessively high or low temperatures, thereby ensuring that the treatment device has high safety and better performance. Efficacy. Specifically, the detection module 250 may transmit the light intensity detected by the light intensity sensor 330 and the temperature detected by the temperature sensor 340 to the control unit 210. The control unit 210 may determine whether the light intensity is too high or too low, and whether the temperature is too high or too low according to the preset light intensity value and the preset temperature value stored in advance, and adjust and control according to the determination result.

The foregoing descriptions are only optional embodiments of the application, and do not limit the scope of the patent for this application. Under the inventive concept of the application, any equivalent structural transformation made by using the content of the specification and drawings of the application, or direct/indirect Applications in other related technical fields are included in the scope of patent protection of this application.
