Description

Technical Field

[0002] Benign prostatic hyperplasia is one of the most common urological diseases in men. Existing minimally invasive treatment techniques for benign prostatic hyperplasia include radiofrequency ablation, microwave ablation, electropermeation ablation, water jet ablation, thermal steam ablation, etc. Among them, the thermal steam ablation treatment technology is to send a steam catheter to the target position and release high-temperature water vapor to achieve the purpose of destroying and ablating diseased tissues. The latent heat released during the condensation process of high-temperature water vapor can cause the cell membrane proteins of diseased tissues to coagulate and denature, resulting in the death of cells at the diseased site. The damaged tissues will be cleared by the body's immune system in the following days or weeks, ultimately achieving the treatment goal.

[0055] For the steam generating device for ablation treatment (hereinafter simply referred to as the steam generating device) according to the embodiments of the present invention, please refer to Figure 1 and Figure 2 , the steam generating device includes an atomization component 100 and a heating component 200. The atomization component 100 is provided with an atomization chamber 101, and the atomization component 100 is adapted to atomize the liquid into spray-like particles; the heating component 200 is provided with a heating channel 201, the atomization chamber 101 is communicated with the heating channel 201, and the heating component 200 is adapted to heat the spray-like particles to the steam state.

[0056] According to the steam generating device of the embodiments of the present invention, the liquid sequentially passes through the atomization chamber 101 and the heating channel 201. The atomization component 100 atomizes the liquid into spray-like particles in the atomization chamber 101, and the spray-like particles are more easily heated to the steam state, thereby greatly improving the steam generation efficiency.

[0057] It can be understood that the atomization component 100 atomizes the liquid into spray-like particles. The sum of the surface areas of the spray-like particles is larger than the liquid surface area of the non-atomized liquid. The larger the surface area, when it passes through the heating channel 201, the heat of the heating component 200 can more easily heat the spray-like particles to the vapor state, thereby accelerating the evaporation rate of the liquid. Secondly, the spray-like particles are more likely to be evenly distributed in the heating channel 201, further improving the utilization efficiency of the heat of the heating channel 201 by the spray-like particles. By atomizing the liquid into spray-like particles through the atomization component 100, better heat transfer effects can be achieved under the same heating power.

[0058] Moreover, the temperature of the generated steam can be controlled by the settings of the atomization component 100 and the heating component 200. It can be understood that the user can control parameters such as the atomization speed of the atomization component 100 by controlling the size and distribution of the spray-like particles of the atomization component 100. At the same time, since the size and distribution of the spray-like particles are controllable, the user can control the heating speed and temperature range of the steam by adjusting the heating temperature of the heating component 200, so that the temperature of the steam used in the steam generating device for ablation treatment can be controlled.

[0059] It should be noted that for the steam generator of the traditional steam generating device, the steam temperature directly heats the liquid to evaporation, and it must heat the liquid to 100 degrees Celsius or above to generate steam. However, in this application, the liquid is atomized into small spray-like particles by the atomization component 100, and then the heating component 200 heats the small spray-like particles to the vapor state. The generated steam temperature can be between 60 degrees Celsius and 100 degrees Celsius.

[0060] It should be noted that the steam temperature in the temperature range of 60 degrees Celsius to 70 degrees Celsius can already treat some hyperplastic diseases. It can be understood that the lower the steam temperature, the less harm to other human tissues. While achieving the same treatment effect with the steam ablation device of this application, the harm to the patient is small.

[0061] It can be understood that the user can control the steam temperature by adjusting the heating temperature of the heating component 200. The steam ablation setting of this application can be provided with different steam temperature ranges according to different treatment stages. For example, in the first stage of treatment, steam with a temperature range of 90 degrees Celsius to 100 degrees Celsius is used, in the second stage of treatment, steam with a temperature range of 80 degrees Celsius to 90 degrees Celsius is used, in the third stage of treatment, steam with a temperature range of 70 degrees Celsius to 80 degrees Celsius is used, and in the fourth stage of treatment, steam with a temperature range of 60 degrees Celsius to 70 degrees Celsius is used. It should be noted that the above examples are not limitations on the present invention, and this application does not limit the specific values of the treatment stages and the corresponding temperature ranges.

[0062] In one embodiment, the liquid is sterile water.

[0063] In one embodiment, the diameter of the spray particles ranges from 1 micrometer to 100 micrometers.

[0064] In one embodiment, the atomization assembly 100 is an ultrasonic atomizer. When the ultrasonic generating device of the ultrasonic atomizer is activated, the atomization sheet 120 of the ultrasonic atomizer generates mechanical vibrations. The oscillation of the ultrasonic waves generates surface waves on the liquid and forms standing waves, thereby dispersing the liquid into spray particles. It can be understood that the size of the spray particles generated by the ultrasonic atomizer is more uniform, and the speed of generating spray particles is fast.

[0065] It should be noted that the atomization assembly 100 being an ultrasonic atomizer here is only an example, rather than a limitation on the atomization assembly 100. The atomization assembly 100 can also be others. For example, a sprayer and a rotary disk atomizer, etc. Among them, the nozzle of the sprayer is provided with small holes, and the liquid is quickly passed through the holes by pressure to form spray particles. The rotary disk atomizer uses centrifugal force to throw the liquid off the disk to form spray particles.

[0066] In one embodiment, the heating assembly 200 is a resistance wire heater, which converts electrical energy into heat energy by means of resistance heating. When an electric current passes through the resistance wire, the resistance wire generates heat and transfers the heat to the surrounding medium to heat it. When the spray particles are sprayed near the resistance wire heater, the spray particles will quickly evaporate to form steam.

[0067] It should be noted that the heating assembly 200 being a resistance wire heater here is only an example, rather than a limitation on the heating assembly 200. The heating assembly 200 can also be others. For example, a ceramic heater, an electromagnetic induction heater, an FPC flexible heating element, a heat exchanger, and a burner, etc. Among them, the heat exchanger conducts heat exchange by means of conduction, convection or radiation. When the spray particles come into contact with the heat medium in the heat exchanger, they will be heated and quickly evaporate to form steam. The burner generates a high-temperature combustion flame by burning gas to heat the spray particles into steam.

[0068] According to an embodiment of the present invention, please refer to Figure 1 , the steam generating device includes a housing 300 and a pressure balancing member 400. The heating assembly 200 is installed in the housing 300, and a steam chamber 301 is formed inside the housing 300; the atomization chamber 101, the heating channel 201, and the steam chamber 301 are communicated in sequence; the pressure balancing member 400 is communicated with the steam chamber 301. The pressure balancing member 400 is adapted to be activated before the heating assembly 200 and the atomization assembly 100 work to generate steam, and is used to balance the air pressure difference between the steam chamber 301 and the outside. When the heating assembly 200 and the atomization assembly 100 are working, the pressure balancing member 400 is disconnected from the outside.

[0069] It can be understood that through the atomization component 100, the liquid can be atomized into spray-like particles in the atomization chamber 101, and through the heating component 200, the spray-like particles passing through the heating channel 201 can be heated to the steam state. The steam floats up into the steam chamber 301 that can accommodate the steam. The more steam generated by the heating component 200, the greater the pressure in the steam chamber 301 drives the steam to leave the steam chamber 301 through the steam delivery component 500 (introduced later).

[0070] It can be understood that the air pressure balancing component 400 can use the mechanical force of the air pressure balancing component 400 to balance the steam pressure inside the steam chamber 301, enabling the steam to flow naturally to the steam delivery component 500, which can effectively enhance the flow rate of the steam.

[0071] It should be noted that the air pressure balancing component 400 can be an air pump or an air valve. The present invention does not limit the specific implementation form of the air pressure balancing component 400.

[0072] According to an embodiment of the present invention, a part of the steam chamber 301 surrounds the outer periphery of the heating channel 201, and the air pressure balancing component 400 is connected to the bottom of the steam chamber 301. It can be understood that when the steam condenses into droplets, they will adhere to the inner wall of the steam chamber 301. Since a part of the steam chamber 301 surrounds the outer periphery of the heating channel 201, when the droplets flow down along the inner wall of the steam chamber 301, they will not directly enter the heating channel 201, avoiding the condensation and backflow of the steam to the heating channel 201.

[0073] It can be understood that the air pressure balancing component 400 can be connected to the bottom of the steam chamber 301, and the air pressure balancing component 400 can be arranged at the bottom of the steam generating device. Such an arrangement can effectively reduce the interference of the air pressure balancing component 400 on the steam delivery component 500.

[0074] Of course, the air pressure balancing component 400 of the present invention can also be connected to other positions of the steam chamber, as long as it can achieve the balance of the steam pressure inside the steam chamber 301.

[0075] According to an embodiment of the present invention, please refer to Figures 1 to 3 , a first pipe section 3211 protruding from the bottom wall of the steam chamber 301 is provided at the bottom of the steam chamber 301, and the first pipe section 3211 is connected to the air pressure balancing component 400. It can be understood that by providing the first pipe section 3211 protruding from the bottom wall at the bottom of the steam chamber 301, the droplets condensed from the steam can be blocked outside the first pipe section 3211, preventing the droplets from flowing back into the air pressure balancing component 400. It can avoid the damage or failure of the internal components of the pump caused by the droplets entering the air pressure balancing component 400, ensure the normal operation of the air pressure balancing component 400, and extend the service life of the air pressure balancing component 400.

[0076] According to an embodiment of the present invention, the steam chamber 301 includes an upper chamber wall 302 that is constricted along the height direction. It can be understood that the upper chamber wall 302 that is constricted along the height direction can cause the steam to accumulate along the height direction on the upper chamber wall 302 and concentrate upward, thereby improving the speed and efficiency of steam delivery.

[0077] According to an embodiment of the present invention, please refer to Figure 1 , Figure 3 and Figure 4 , a liquid storage chamber 303 is provided at the bottom of the housing 300. The liquid storage chamber 303 communicates with the steam chamber 301, and the liquid storage chamber 303 is used to store the droplets that flow back from the steam chamber 301. It can be understood that by providing the liquid storage chamber 303, the steam generating device has a storage space for the droplets condensed from the steam, which can prevent the droplets condensed from the steam from accumulating and affecting the normal operation of the atomization assembly 100 and the heating assembly 200, is beneficial to improving the steam generation efficiency, and the droplets stored in the liquid storage chamber 303 can be collected and reused. Of course, when the droplets do not need to be recovered, the droplets stored in the liquid storage chamber 303 can also be discharged.

[0078] According to an embodiment of the present invention, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 , a circular partition 3221 is provided at the bottom of the housing 300. The circular partition 3221 encloses an installation cavity 304. The installation cavity 304 is used to install the atomization assembly 100. The liquid storage chamber 303 is arranged on the outer periphery of the circular partition 3221. The circular partition 3221 is provided with a through hole 3222, and the through hole 3222 communicates the liquid storage chamber 303 and the installation cavity 304. It can be understood that the circular partition 3221 separates the liquid storage chamber 303 and the installation cavity 304. The liquid storage chamber 303 is arranged on the outer periphery of the circular partition 3221, and the installation cavity 304 is located in the inner circle formed by the enclosure of the circular partition 3221. The through hole 3222 communicates the liquid storage chamber 303 and the installation cavity 304. The droplets stored in the liquid storage chamber 303 that flow back from the steam chamber 301 can enter the installation cavity 304 through the through hole 3222 and be provided for use by the atomization assembly 100 in the installation cavity 304.

[0079] According to an embodiment of the present invention, please refer to Figures 1 to 3 , the atomization assembly 100 includes a liquid guide 110 and an atomization sheet 120. The installation cavity 304 includes a liquid guide cavity 305 and an atomization cavity 101 that are arranged in sequence and communicate with each other. The liquid guide 110 is fixed in the liquid guide cavity 305, the atomization sheet 120 is arranged in the atomization cavity 101, the through hole 3222 communicates with the atomization cavity 101, and a through groove 3223 is provided on the bottom plate of the atomization cavity 101. The through groove 3223 communicates the through hole 3222 and the liquid guide cavity 305.

[0080] It can be understood that the liquid guide 110 contacts the liquid and can guide the liquid to the atomizing sheet 120. The liquid guide 110 is pre-pressed against the atomizing sheet 120. The liquid flows through the liquid guide 110 and contacts the atomizing sheet 120. The atomizing sheet 120 generates continuous mechanical vibrations, causing the liquid to break up into spray-like particles. The spray-like particles float up into the heating channel 201 and are heated to the steam state.

[0081] It can be understood that the liquid guide 110 can filter large particle impurities in the liquid and effectively prevent large particle impurity objects from entering the atomizing chamber 101 and affecting the normal operation of the atomizing sheet 120. The liquid guide 110 can be a medical fiber or medical cotton with excellent liquid guiding performance, or a honeycomb ceramic body.

[0082] It can be understood that the through groove 3223 has a drainage effect on the liquid storage chamber 303 and can guide the liquid droplets flowing back from the steam chamber 301 in the liquid storage chamber 303 to the liquid guide 110, facilitating the secondary utilization of the liquid droplets by the atomizing assembly 100.

[0083] In one embodiment, please refer to Figure 1 , the liquid guide 110 includes a first liquid guide and a second liquid guide. The liquid guide cavity 305 includes a first liquid guide cavity and a second liquid guide cavity. The installation cavity 304 includes a first liquid guide cavity, a second liquid guide cavity, and an atomizing chamber 101 that are arranged in sequence and communicated. The first liquid guide is fixed in the first liquid guide cavity, the second liquid guide is fixed in the second liquid guide cavity, the atomizing sheet 120 is arranged in the atomizing chamber 101, and the through groove 3223 communicates the through hole 3222 with the second liquid guide cavity. The shape of the first liquid guide cavity is adapted to the shape of the liquid inlet pipe 600 (introduced later), and the shape of the second liquid guide cavity is adapted to the shape of the atomizing sheet 120. The first liquid guide is adapted to guide the liquid in the liquid inlet pipe 600 to the second liquid guide, and the second liquid guide guides the liquid to the atomizing sheet 120.

[0084] According to an embodiment of the present invention, please refer to Figure 1 and Figure 6 , the number of the through grooves 3223 is multiple, and the multiple through grooves 3223 are evenly distributed on the bottom plate of the atomizing chamber 101. It can be understood that the multiple through grooves 3223 can guide the liquid to the liquid guide 110 evenly in multiple directions, and the liquid absorbed by the liquid guide 110 is more uniform. The multiple through grooves 3223 can prevent the reflux liquid droplets from accumulating or staying in the atomizing chamber 101. Even if one through groove 3223 is blocked, the liquid droplets can continue to flow back through other channels.

[0085] According to an embodiment of the present invention, please refer to Figure 1The atomizing chamber 101 and the liquid guiding chamber 305 are coaxially arranged. It can be understood that when the atomizing chamber 101 and the liquid guiding chamber 305 are coaxially arranged, the transmission path from the liquid guiding chamber 305 to the atomizing chamber 101 is shorter, and at the same time, the liquid level of the liquid guiding chamber 305 and the atomizing plate 120 are coaxial, so that the spray-like small particles generated by the atomizing plate 120 are more uniform.

[0086] According to one embodiment of the present invention, please refer to Figure 1 The housing 300 includes a steam chamber cover 310 and a steam chamber base 320, and the heating assembly 200 and the atomizing assembly 100 are both fixed to the steam chamber base 320. It is understandable that the heating assembly 200 and the atomizing assembly 100 are mounted on the steam chamber base 320, and the steam chamber cover 310 is connected to the steam chamber base 320, and a steam chamber 301 is formed between the steam chamber cover 310 and the steam chamber base 320 on which the heating assembly 200 and the atomizing assembly 100 are mounted.

[0087] It is understood that during installation and assembly, the heating assembly 200 and the atomizer assembly 100 are fixed to the steam chamber base 320 to ensure that the heating assembly 200 and the atomizer assembly 100 are in a stable position before the steam chamber cover 310 is installed on the steam chamber base 320, thereby facilitating the assembly of the steam chamber cover 310. In addition, such an arrangement facilitates the user's inspection of the heating assembly 200 and the atomizer assembly 100, as the user only needs to remove the steam chamber cover 310, thereby reducing the user's workload.

[0088] According to one embodiment of the present invention, please refer to Figure 1 、 Figure 4 and Figure 5 The steam chamber base 320 includes a steam chamber lower shell 3210 , the heating assembly 200 includes a heating fixture 210 and a mounting tube 220 , the heating fixture 210 is connected to the steam chamber lower shell 3210 , and the mounting tube 220 is mounted on the heating fixture 210 .

[0089] It is understandable that the heating fixture 210 is used to fix the mounting tube 220 , which can ensure the stability of the position of the mounting tube 220 and further ensure the stability of the heating channel 201 .

[0090] In one embodiment, the mounting tube 220 is provided with a heating ring 221, which surrounds the mounting tube 220 to form a heating channel 201. It will be appreciated that the heating fixture 210 can also prevent the mounting tube 220 provided with the heating ring 221 from directly contacting the steam chamber lower shell 3210, thereby reducing heat conduction between the heating ring 221 and the steam chamber lower shell 3210. The heating fixture 210 can also act as a thermal insulation layer to prevent the steam chamber lower shell 3210 from overheating.

[0091] It can be understood that the heating ring 221 can be formed by a single annular heating element, or two or more heating elements can be installed around the installation pipe 220 for one week to form the heating ring 221. The two heating elements can be arranged at intervals or connected to each other. What leaves the atomization chamber 101 can enter the heating channel 201 formed by the heating ring 221, and the spray-like particles can be quickly heated to the steam state when contacting the heating ring 221. Of course, the heating ring 221 can also transfer heat to the surrounding medium (such as air and the installation pipe 220), and the spray-like particles can be heated to the steam state without directly contacting the heating ring 221.

[0092] In one embodiment, there are multiple heating rings 221, and the multiple heating rings 221 are arranged along the extending direction of the heating channel 201. It can be understood that the multiple heating rings 221 can evenly distribute heat throughout the entire length of the heating channel 201 to ensure that the liquid or gas is evenly heated when passing through the heating channel 201. In addition, the multiple heating rings 221 can be controlled separately, making it easier to achieve precise temperature control and adjustment. For example, the heating ring 221 near the end of the heating channel 201 can have a higher temperature to ensure that the spray-like particles at the end of the heating channel 201 are heated to the steam state.

[0093] According to one embodiment of the present invention, please refer to Figure 1 and Figure 3 , the heating assembly 200 further includes a heating housing 230 and a sensor 240. The sensor 240 covers the installation pipe 220, or the installation pipe 220 covers the heating housing 230. The sensor 240 is arranged between the heating housing 230 and the installation pipe 220, and the probe of the sensor 240 is arranged at the outlet of the heating channel 201.

[0094] It can be understood that whether the sensor 240 covers the installation pipe 220 or the installation pipe 220 covers the heating housing 230, an installation space for electrical components (including the sensor 240) is formed between the heating housing 230 and the installation pipe 220. This installation space can reduce the influence of external pollutants (steam or spray-like particles) on the electrical components, thereby reducing the risk of component wear, corrosion, or short circuit.

[0095] It can be understood that arranging the probe of the sensor 240 at the outlet of the heating channel 201 can more accurately reflect the actual temperature situation in the heating channel 201, thereby achieving more precise control of the steam temperature.

[0096] In one embodiment, the heating assembly includes a sensor fixing member 270, and the sensor fixing member 270 is used to fix the sensor 240. The sensor fixing member 270 can be arranged around the end of the installation pipe 220, or can be separately arranged on one side of the end of the installation pipe 220.

[0097] According to one embodiment of the present invention, a heating sealing pad 250 is provided between the heating shell 230 and the mounting tube 220 , and a heating sealing ring 260 is provided between the mounting tube 220 and the heating fixture 210 .

[0098] It is understood that the heating seal 250 can prevent the mounting tube 220, equipped with the heating ring 221, from directly contacting the steam chamber lower shell 3210, thereby reducing heat conduction between the heating outer shell 230 and the mounting tube 220, and ensuring a tight seal between the heating outer shell 230 and the mounting tube 220. Similarly, the heating seal 260 can prevent the mounting tube 220, equipped with the heating ring 221, from directly contacting the heating fixture 210, thereby reducing heat conduction between the mounting tube 220 and the heating fixture 210, and ensuring a tight seal between the mounting tube 220 and the heating fixture 210.

[0099] According to one embodiment of the present invention, please refer to Figure 1 and Figure 5 The steam chamber lower shell 3210 is provided with a second pipe section 3212 that protrudes toward the steam chamber 301. The second pipe section 3212 is used to mount the heating assembly 200. It is understood that by providing the steam chamber lower shell 3210 with the second pipe section 3212 that protrudes toward the steam chamber 301, condensed steam droplets can be blocked outside the second pipe section 3212, preventing the droplets from directly flowing back into the heating assembly 200. This can prevent the droplets from directly entering the heating assembly 200 and affecting the overall heating efficiency, thereby ensuring the normal operation of the heating assembly 200.

[0100] In one embodiment, the second pipe section 3212 is provided with an avoidance groove for installing the sensor 240 and electrical components connecting the sensor 240 and the heating ring 221 .

[0101] According to one embodiment of the present invention, please refer to Figure 1 The top of the steam chamber cover 310 is provided with a first mounting interface 311, which is connected to the steam chamber 301. It can be understood that the top space of the steam chamber cover 310 is large and has strong expandability. Through the first mounting interface 311, different steam delivery components 500 can be easily added to meet different treatment needs.

[0102] According to one embodiment of the present invention, please refer to Figure 1 and Figure 6, the vapor chamber base 320 further includes an atomization fixing shell 3220. The atomization fixing shell 3220 is connected to the vapor chamber lower shell 3210 and is used for installing the atomization component 100. It can be understood that the vapor chamber lower shell 3210 is used for installing the heating component 200, and the atomization fixing shell 3220 is used for installing the atomization component 100. The heating function and the atomization function are independent modules respectively. Such a setting not only facilitates maintenance but also facilitates the assembly among the vapor chamber lower shell 3210, the heating component 200, the atomization fixing shell 3220, and the atomization component 100.

[0103] In one embodiment, please refer to Figure 1 and Figure 6 , the atomization fixing shell 3220 is provided with an annular partition 3221. The annular partition 3221 encloses to form the installation cavity 304 mentioned above. The liquid storage cavity 303 is arranged on the outer periphery of the annular partition 3221. The annular partition 3221 is provided with through holes 3222, and the through holes 3222 communicate the liquid storage cavity 303 and the installation cavity 304. The bottom plate of the atomization cavity 101 is provided with a through groove 3223, and the through groove 3223 communicates the through hole 3222 with the liquid guiding cavity 305.

[0104] It can be understood that the atomization fixing shell 3220 integrates the installation function of the atomization component 100 and the function of recycling the liquid flowing back from the vapor chamber 301. Through the settings of the annular partition 3221, the through holes 3222, and the through groove 3223, the liquid flowing back and the atomization component are closely connected, effectively improving the space utilization rate.

[0105] According to an embodiment of the present invention, please refer to Figure 1 , Figure 5 and Figure 6 , the vapor chamber lower shell 3210 is provided with an opening 3213, and the opening 3213 is arranged above the liquid storage cavity 303. It can be understood that the opening 3213 can ensure that the liquid flowing back from the vapor chamber 301 enters the liquid storage cavity 303. The bottom plate of the vapor chamber lower shell can also be provided with a liquid guiding surface (not marked in the figure) inclined towards the opening 3213. When the vapor generating device is placed flat, the liquid can automatically flow towards the opening 3213 according to its own gravity and then enter the liquid storage cavity 303.

[0106] It should be noted that the number of the openings 3213 matches the number of the liquid storage cavities 303. For example, Figure 4 the number of the liquid storage cavities 303 is two, Figure 3 and the number of the openings 3213 is also two. It should be noted that the number of the openings 3213 matching the number of the liquid storage cavities 303 can be set according to a one-to-one mathematical relationship, or can be set without a one-to-one relationship. For example, multiple openings 3213 correspond to one liquid storage cavity 303.

[0107] According to an embodiment of the present invention, please refer to Figure 1 and Figure 3 , a steam chamber sealing ring 301 is provided on the contact surface between the upper cover 310 of the steam chamber and the lower shell 3210 of the steam chamber, and an atomization seal 340 is provided on the contact surface between the lower shell 3210 of the steam chamber and the atomization fixing shell 3220. It can be understood that the steam chamber sealing ring 301 can ensure the sealing performance between the upper cover 310 of the steam chamber and the lower shell 3210 of the steam chamber. The atomization seal 340 can ensure the sealing performance between the lower shell 3210 of the steam chamber and the atomization fixing shell 3220.

[0108] It should be noted that the contact surface between the upper cover 310 of the steam chamber and the lower shell 3210 of the steam chamber or the contact surface between the lower shell 3210 of the steam chamber and the atomization fixing shell 3220 can be a stepped surface.

[0109] According to an embodiment of the present invention, please refer to Figure 1 , the bottom of the atomization fixing shell 3220 is provided with a second installation interface 3224, a third installation interface 3225, and a fourth installation interface 3226. The second installation interface 3224 communicates with the atomization chamber 101, the third installation interface 3225 communicates with the heating channel 201, and the fourth installation interface 3226 communicates with the steam chamber 301.

[0110] It can be understood that the second installation interface 3224, the third installation interface 3225, and the fourth installation interface 3226 are located at the bottom of the atomization fixing shell 3220. The bottom space of the atomization fixing shell 3220 is large and has strong scalability, which can facilitate the addition of corresponding input components. At the same time, the second installation interface 3224, the third installation interface 3225, and the fourth installation interface 3226 are all input interfaces of the steam generating device and are located at the bottom of the atomization fixing shell 3220, while the first installation interface 311 is located at the top of the upper cover 310 of the steam chamber, which can reduce the chance of mutual interference. In addition, the liquid or gas located in the atomization chamber 101 or the steam chamber 301 usually flows downward, and the second installation interface 3224, the third installation interface 3225, and the fourth installation interface 3226 located at the bottom of the atomization fixing shell 3220 help to reduce the risk of leakage.

[0111] According to an embodiment of the present invention, the second installation interface 3224 is provided in the middle of the atomization fixing shell 3220.

It can be understood that through the mutual spacing of the first installation interface 311, the second installation interface 3224, and the third installation interface 3225, the space utilization rate of the atomization fixing shell 3220 reaches the maximum, and the three interfaces do not interfere with each other.

[0112] An embodiment of the present invention further provides a steam ablation device. Please refer to Figure 1 , the steam ablation device includes the steam generating device for ablation treatment mentioned above.

The liquid channel 601 is formed inside it, and the liquid flows into the interior of the steam ablation device through the liquid channel 601 to ensure that the liquid flows from the liquid inlet pipe 600 into the atomization chamber 101. The atomization chamber 101 is the part for converting the liquid into an atomized state, and the liquid is dispersed into spray-like particles through the atomization assembly 100. The heating channel 201 is for heating the spray-like particles to turn the spray-like particles into steam. The steam channel 501 is the channel for transmitting steam. In the heating channel 201, the liquid droplets are heated and converted into steam, and then the steam is transmitted to the target position through the steam channel 501 of the steam delivery assembly 500.

[0114] In some embodiments, a steam chamber 301 is further provided between the heating channel 201 and the steam channel 501.
