[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Such as Figure 1An ultrasonic treatment head as shown includes a housing 100, a cover 200, a sound-transmitting membrane 400, an ultrasonic imaging probe 600, and an ultrasonic treatment probe 500. The housing 100 includes a side portion 101 and a bottom portion 102. The side portion 101 and the bottom portion 102 enclose an assembly space 01. An assembly opening 02 is provided at one end of the side portion 101 away from the bottom portion 102. The bottom portion 102 is provided with a sound-transmitting window 04 for transmitting sound waves (i.e., in actual use, the sound waves emitted by the ultrasonic imaging probe 600 and the ultrasonic treatment probe 500 are emitted through the sound-transmitting window 04); the cover 200 is hermetically covered on the assembly opening 02; the sound-transmitting membrane 400 is disposed on the sound-transmitting window 04 and is hermetically connected to the bottom portion 102; the ultrasonic imaging probe 600 and the ultrasonic treatment probe 500 are connected to form a composite probe body, and the composite probe body is connected to the cover 200, and of course, it can also be connected to the housing 100; the cover 200 and the sound-transmitting membrane 400 respectively seal the assembly opening 02 and the sound-transmitting window 04 to make the assembly space 01 airtight. The assembly space 01 is used to accommodate a sound-transmitting liquid for conducting sound waves, and the composite probe body is disposed in the assembly space 01 and immersed in the sound-transmitting liquid. Through the above design, during the treatment process of the ultrasonic treatment head provided by the present application, the ultrasonic imaging probe 600 can image and record the state of the skin tissue, solving the problem that the action situation of ultrasonic waves and tissue changes cannot usually be dynamically displayed in real time during the treatment process.

[0036] The technical details of each component will be introduced one by one below.

[0037] In some embodiments, as Figure 2 、 Figure 3 shown, the above-mentioned cover 200 is provided with a liquid injection port 07 for injecting the sound-transmitting liquid into the interior of the assembly space 01. The liquid injection port 07 is communicated with the assembly space 01; correspondingly, the cover 200 is further provided with a sealing plug 21, and the sealing plug 21 is used to block the liquid injection port 07 to prevent the sound-transmitting liquid from overflowing from the liquid injection port 07 due to vibration during the use of the ultrasonic treatment head.

[0038] In some embodiments, as Figure 2 、 Figure 4 、 Figure 5 shown, the above-mentioned housing 100 includes an inner housing 11 and an outer housing 12. The inner housing 11 and the outer housing 12 are nested. The assembly space 01 is disposed in the inner housing 11. The inner housing 11 and the outer housing 12 are respectively provided with a first sound-transmitting opening 05 and a second sound-transmitting opening 06. The first sound-transmitting opening 05 and the second sound-transmitting opening 06 coincide with each other to form the sound-transmitting window 04.

[0039] A flange 111 is disposed around the edge of one side of the first sound transmission port 05 close to the outer shell 12, and a pressure ring 121 is disposed around the second sound transmission port 06. The pressure ring 121 is used to abut against the flange 111 to clamp the edge of the sound transmission film 400. During the actual assembly process, the pressure ring 121 can be sleeved outside the flange 111. The sound transmission film 400 is disposed between the inner shell 11 and the outer shell 12. The flange 111 at the edge of the first sound transmission port 05 of the inner shell 11 will push the sound transmission film 400 towards the outer shell 12, and the pressure ring 121 at the edge of the second sound transmission port 06 of the outer shell 12 will push the edge of the sound transmission film 400 towards the inner shell 11. Under the opposite pushing actions of the flange 111 and the pressure ring 121, the edge of the sound transmission film 400 will be clamped between the flange 111 and the pressure ring 121, and a sealed structure will be formed to seal the first port. Through the above settings, the clamping actions of the flange 111 and the pressure ring 121 can quickly assemble and fix the sound transmission film 400 without operations such as adhesion. And in addition to the above effects, under the opposite pushing actions of the flange 111 and the pressure ring 121, the sound transmission film 400 can also be tightened, so that after the sound transmission film 400 is assembled, the part opposite to the sound transmission window 04 can be very flat, and it is not easy to have depressions and wrinkles. In this way, the sound waves emitted by the ultrasonic imaging probe 600 and the ultrasonic treatment probe 500 can stably pass through the sound transmission window 04 to image and treat the skin, avoiding interference with the sound waves.

[0040] In some other embodiments, vent holes are formed in the inner shell 11 or the outer shell 12, and an installation interlayer is formed between the inner shell 11 and the outer shell 12. The vent holes communicate with the installation interlayer. During the actual assembly process, when the inner shell 11 and the outer shell 12 are nested, the air between their connection parts needs to be discharged so that the inner shell 11 and the outer shell 12 can closely fit with each other.

[0041] In some embodiments, as Figure 2 、 Figure 5 shown, the inner shell 11 is hermetically connected to the cover body 200, and a sealing ring 300 is disposed between the inner shell 11 and the cover body 200. The sealing ring 300 can enhance the sealing performance between the inner shell 11 and the cover body 200 to prevent the leakage of the sound transmission liquid.

[0042] In some embodiments, as Figure 2 、 Figure 3 shown, the ultrasonic treatment head provided by the present application further includes a moving mechanism 700. The moving mechanism 700 is connected to the cover body 200 and / or the housing 100, and the composite probe body is disposed at the moving end of the moving mechanism 700. The composite probe body is disposed opposite to the sound transmission window 04. The moving mechanism 700 drives the composite probe body to move relative to the sound transmission window 04 to change the position of the composite probe, so as to treat and image different areas of the skin.

[0043] It can be understood that during the above operation, since the composite probe is arranged inside the device, it is impossible to directly determine the position of the composite probe. Furthermore, in some other embodiments, a laser emitting device is arranged on one side of the composite probe relative to the acoustic window 04. The laser emitting device is used to emit laser relative to the acoustic window 04. After the laser passes through the acoustic window 04, it will irradiate the skin, thereby facilitating the user to identify and determine the position of the composite probe during the operation.

[0044] In some embodiments, the movable mechanism 700 includes a guide rail 71, a sliding sleeve 72, and a movable frame 73. The guide rail 71 is connected to the cover body 200 and / or the housing 100. The guide rail 71 extends along the length direction of the acoustic window 04. The sliding sleeve 72 is slidably connected to the guide rail 71. One end of the movable frame 73 is connected to the sliding sleeve 72.

[0045] As Figure 5 shown, the guide rail 71 is connected to the cover body 200. Through the above design, the composite probe can slide along the guide rail 71 following the movable frame 73, thereby changing the position of the composite probe to facilitate the treatment of the skin at different parts.

[0046] In order to facilitate the electrical connection between the composite probe and other devices, in some embodiments, the movable frame 73 is provided with a wire passing channel to facilitate the threading of the wire connecting the composite probe, thereby avoiding damage to the internal circuit during the movement of the movable frame 73.

[0047] In some embodiments, as Figure 2 、 Figure 5 shown, the housing 100 is provided with a through hole 03, and the through hole 03 is arranged opposite to the movable frame 73. The ultrasonic treatment head further includes a handle for pushing the movable frame 73 to move along the guide rail 71. One end of the handle passes through the through hole 03 and is detachably connected to the movable frame 73. In actual use, the operator passes the handle through the through hole 03 and connects it to the movable frame 73, and then can pull or push the movable frame 73 to move through the handle, thereby changing the position of the composite probe.

[0048] In order to prevent the transmission fluid from leaking through the through hole 03, as Figure 2 、 Figure 5As shown in the figure, the ultrasonic treatment head provided by the present application further includes a sealing sleeve 800. One end of the sealing sleeve 800 is hermetically connected to the edge of one side of the through hole 03 opposite to the movable frame 73. The tube body of the sealing sleeve 800 can be telescoped. The other end of the sealing sleeve 800 is hermetically connected to the movable frame 73. One end of the handle passes through the through hole 03 and the lumen of the sealing sleeve 800 in sequence and is detachably connected to the movable frame 73. In this way, a channel isolated from the assembly space 01 can be formed between the movable frame 73 and the through hole 03, so that during the process of the operator moving the movable frame 73 through the handle, the transmission liquid will not leak from the through hole 03.

[0049] Specifically, as Figure 5 shown in the figure, one of the movable frame 73 and the handle is provided with a magnetic attraction part 731, and the other of the movable frame 73 and the handle is provided with a magnet 08. The magnet 08 is used for magnetic attraction to the magnetic attraction part 731. One end of the handle passes through the through hole 03 and the lumen of the sealing sleeve 800 in sequence and is magnetically connected to the movable frame 73. Preferably, the magnet 08 is arranged on the handle, and the magnetic attraction part 731 is arranged on the movable frame 73. Arranging the magnet 08 on the handle can facilitate the replacement of the magnet 08 when the magnetism of the magnet 08 is insufficient; if the magnet 08 is arranged on the movable frame 73, it is not easy to operate when replacing it through the through hole 03. The magnetic attraction method is relatively fast, and the operator does not need to align the handle very accurately with the magnetic attraction part 731. Under the action of the magnetic force, the handle will automatically be attracted to the magnetic attraction part 731 after extending into the through hole 03.

[0050] The present application also provides an assembly method for assembling the above ultrasonic treatment head. The assembly method of the ultrasonic treatment head is as follows:

[0051] S1. Fix the ultrasonic treatment probe 500 and the ultrasonic imaging probe 600 at the movable end of the movable mechanism 700, and then assemble the movable mechanism 700 into the assembly space 01;

[0052] S2. Assemble the sound transmission film 400. Place the sound transmission film 400 on the side of the second sound transmission port 06 close to the inner shell 11, and then sleeved the outer shell 12 on the outside of the inner shell 11. At this time, the flange 111 and the pressing ring 121 will respectively abut against both sides of the sound transmission film 400. When the outer shell 12 and the inner shell 11 are sleeved, the edge of the sound transmission film 400 will be clamped between the flange 111 and the pressing ring 121, thereby fixing the sound transmission film 400. Under the clamping action of the flange 111 and the pressing ring 121, the edge of the sound transmission film 400 will produce a sealing effect. The clamping action of the flange 111 and the pressing ring 121 can quickly assemble and fix the sound transmission film 400 without operations such as adhesion, and the assembly is fast.

[0053] S3. Place the sealing ring 300 between the cover body 200 and the inner shell 11, and then connect and fix the cover body 200 to the inner shell 11. The sealing ring 300 is pressed between the cover body 200 and the inner shell 11, thereby sealing the assembly port 02.

[0054] S4. Fill the acoustic transmission liquid. Remove the sealing plug 21 from the liquid injection port 07, and then fill the interior of the assembly space 01 with the acoustic transmission liquid through the liquid injection port 07 until the assembly space 01 is full, and then use the sealing plug 21 to block the liquid injection port 07.

[0055] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0056] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0057] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

When the outer shell (12) and the inner shell (11) are sleeved, the edge of the sound transmission membrane (400) will be clamped between the flange (111) and the pressing ring (121), thereby fixing the sound transmission membrane (400). Under the clamping action of the flange (111) and the pressing ring (121), the edge of the sound transmission membrane (400) will produce a sealing effect. S3. Place the sealing ring (300) between the cover body (200) and the inner shell (11), and then connect and fix the cover body (200) and the inner shell (11). The sealing ring (300) is pressed tightly between the cover body (200) and the inner shell (11), thereby sealing the assembly port (02). S4. Inject the acoustic transmission liquid. Remove the sealing plug (21) from the liquid injection port (07), then inject the acoustic transmission liquid into the interior of the assembly space (01) through the liquid injection port (07) until the assembly space (01) is filled, and then use the sealing plug (21) to block the liquid injection port (07).
