Description

Technical Field

[0001] This invention relates to the field of ultrasound therapy technology, and in particular to an ultrasound therapy device and method based on the synergistic effect of multiple ultrasound effects. Background Technology

[0002] Ultrasound therapy is a technique that utilizes the physical effects of ultrasound waves (such as thermal, mechanical, and cavitation effects) to exert biological effects on human tissues, thereby achieving therapeutic goals. Currently, ultrasound therapy is widely used in various medical fields, including rehabilitation therapy, soft tissue injury repair, tumor ablation, and transdermal drug delivery.

[0003] Traditional ultrasound therapy devices typically use only a single frequency and mode of continuous or pulsed wave output, which can only exert one dominant effect. However, in clinical practice, many complex diseases (such as deep fascial adhesions, chronic inflammation, postoperative edema, etc.) often require the synergistic effect of multiple ultrasound effects in time and space to achieve the best therapeutic effect.

[0004] In existing handheld ultrasound therapy devices, the handle and treatment head are mostly fixedly connected, making it impossible to flexibly adjust the extension length of the treatment head or replace it with different sizes and shapes according to the treatment site (such as joint surfaces, sides of the spine, etc.). Prolonged use can easily cause operator fatigue, affecting the stability and precision of the treatment. Furthermore, the pressure between the treatment head and the skin lacks real-time feedback; operators rely solely on experience, which can easily lead to patient discomfort due to excessive pressure or ineffective ultrasound energy delivery to the tissue due to insufficient pressure.

[0005] Therefore, there is an urgent need for an ultrasound therapy device and method that can achieve synergistic control of multiple ultrasound effects, has an adjustable structure, and provides pressure feedback for fit, in order to solve the aforementioned problems in the existing technology. Summary of the Invention

[0006] The purpose of this invention is to provide an ultrasound therapy device and method with synergistic multi-effect ultrasound, in order to solve the technical problems of single ultrasound effect, lack of synergistic control, and inconvenient operation in the prior art.

[0007] This invention is implemented as follows: an ultrasound therapy device based on the synergistic effect of multiple ultrasound effects, comprising: The main unit of the therapeutic device integrates a multi-effect collaborative control module, and the main unit of the therapeutic device is provided with at least one port; A treatment assembly comprising a composite ultrasound transducer array, the composite ultrasound transducer array including at least two independently driveable effect regions configured to produce different types of ultrasound effects; and A handle assembly, which is electrically and pluggably connected to the main unit of the therapeutic instrument via the socket and is used for the operator to hold; The multi-effect synergistic control module is electrically connected to the composite ultrasonic transducer array and is configured to control the driving parameters of each effect region so that at least two effect regions generate different ultrasonic effects simultaneously or at different times.

[0008] A further technical solution of the present invention is: the composite ultrasonic transducer array includes a central effect region, an intermediate effect region and an outer effect region distributed sequentially from the center outward, with each region separated by a silicone insulating layer.

[0009] A further technical solution of the present invention is that the treatment component further includes: A flexible coupling layer disposed on the working surface of the composite ultrasonic transducer array; and A cooling cavity is arranged around the composite ultrasonic transducer array, and the housing of the treatment component is provided with a fluid exchange opening communicating with the cooling cavity.

[0010] A further technical solution of the present invention is: the handle assembly includes a housing and a telescopic adjustment mechanism disposed within the housing; the treatment component is connected to the housing via the telescopic adjustment mechanism, and the telescopic adjustment mechanism is capable of changing the axial extension length of the treatment component relative to the housing.

[0011] A further technical solution of the present invention is: it also includes a quick-release assembly; the quick-release assembly includes a positioning ring and at least one locking block disposed on the non-working surface of the treatment assembly, and a locking groove disposed at the end of the telescopic adjustment mechanism; the locking block is connected to the rotating shaft of the positioning ring and is provided with a reset torsion spring, and the locking block and the locking groove form an unlockable locking connection.

[0012] A further technical solution of the present invention is: the telescopic adjustment mechanism includes: An adjusting rod, one end of which is connected to the treatment component, and the other end which is slidably disposed within the movable cavity inside the housing; A first elastic element is disposed within the movable chamber, with its two ends respectively abutting against the adjusting rod and the inner wall of the movable chamber, and tending to force the adjusting rod to extend outward; and A locking assembly, disposed on the housing, is used to overcome the elastic force of the first elastic element and lock the adjusting rod in multiple different axial positions.

[0013] A further technical solution of the present invention is as follows: the locking assembly includes a sliding key and a fixing sleeve; the fixing sleeve is sleeved on the adjusting rod and linked with the sliding key, and the inner wall of the fixing sleeve is provided with a conical surface; the movable chamber is also provided with a fixing block that is fixed relative to the adjusting rod, and the fixing block has a conical surface that matches the conical surface of the fixing sleeve; by moving the sliding key, the fixing sleeve can be driven to move axially, thereby releasing or clamping the fixing block.

[0014] A further technical solution of the present invention is that the locking assembly further includes a second elastic member, the two ends of which abut against the sliding key and the housing respectively, and tend to force the fixing sleeve to maintain the locked state of holding the fixing block tightly.

[0015] A further technical solution of the present invention is: a pressure sensor is provided on the treatment component, and multiple indicator lights are provided on the housing of the handle component; the pressure sensor is electrically connected to the multi-effect synergistic control module, and the multi-effect synergistic control module controls the indicator lights to indicate the current fitting pressure state with different colors or flashing frequencies according to the feedback value of the pressure sensor.

[0016] A treatment method based on a synergistic multi-effect ultrasound therapy device includes the following steps: S1: Apply the treatment component to the patient's treatment area and adjust the application pressure to a preset threshold range based on feedback from the pressure sensor and indicator light. S2: Set and input treatment parameters through the interactive interface of the treatment device host; S3: Activate the multi-effect synergistic control module, first drive the effect area that generates thermal effect to output ultrasound waves to preheat the target tissue; S4: After preheating is started, the effect area that produces mechanical effect is driven to output ultrasound to apply mechanical action to the preheated tissue; S5: After the preset conditions are met, the effect area that produces cavitation effect is driven to output ultrasound waves to apply cavitation effect to the tissue.

[0017] The beneficial effects of this invention are: 1.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0024] like Figure 1 As shown, this embodiment provides an ultrasound therapy device based on the synergistic effect of multiple ultrasound effects. The device includes a main unit 1, a handle assembly 3, and a treatment assembly 4.

[0025] Specifically, the main unit 1 of the therapeutic device has a box-like structure, which integrates a multi-effect collaborative control module, for example, implemented using a digital signal processor combined with a field-programmable gate array, to independently control the frequency, power, duty cycle, and output timing of multiple ultrasound output channels. The front panel of the main unit 1 is equipped with an intelligent touch screen (not labeled in the diagram), which is used to input treatment parameters such as treatment mode, total duration, power ratio of each effect zone, etc., and to display the working status in real time.

[0026] The main unit 1 is also equipped with multiple equally spaced ports 2 so as to connect multiple handle components or spare interfaces at the same time.

[0027] like Figure 3 As shown, the handle assembly 3 is for the operator to grip, and its tail end is connected to a quick-connect plug via a flexible cable. This quick-connect plug is compatible with the socket 2 on the main unit, enabling a pluggable electrical connection. This structure allows the handle assembly to be quickly changed to different sizes of treatment heads or to be sterilized and maintained as needed.

[0028] The specific structure of the handle assembly 3 is as follows: Figure 3 as well as Figure 4 As shown, it includes a housing 31, a telescopic adjustment mechanism disposed within the housing 31, and a locking assembly 34. The housing 31 is generally cylindrical and has an internal movable chamber 311.

[0029] Specifically, the telescopic adjustment mechanism includes an adjusting rod 32 and a first elastic element 35. One end of the adjusting rod 32 is connected to the treatment component 4, and the other end extends into the movable chamber 311 and can slide axially. The first elastic element 35 is a compression spring, sleeved on the adjusting rod 32, with its two ends abutting against the flange of the adjusting rod 32 and the inner wall of the movable chamber 311, respectively, tending to push the adjusting rod 32 outward, i.e., toward the treatment component.

[0030] like Figure 4 as well as Figure 5 As shown, the locking assembly 34 is used to overcome the elastic force of the first elastic element 35 and lock the adjusting rod 32 in multiple different axial positions.

[0031] Specifically, the locking assembly 34 includes a sliding key 341, a fixing sleeve 342, and a fixing block 344. The fixing block 344 is fixed to the adjusting rod 32, and its outer surface is conical. The fixing sleeve 342 is sleeved on the adjusting rod 32, and its inner wall has a conical surface that mates with the fixing block 344. The sliding key 341 is slidably installed in a keyway on the side wall of the housing 31 and is linked with the fixing sleeve 342. When the operator moves the sliding key 341 up or down, it can drive the fixing sleeve 342 to move axially, causing the inner conical surface of the fixing sleeve 342 to disengage from the outer conical surface of the fixing block 344. At this time, the adjusting rod 32 can extend and retract freely. After the sliding key 341 is released, the second elastic element 343, such as a return spring, pushes the sliding key 341 back to its original position, and the fixing sleeve 342 re-clamps the fixing block 344, using the self-locking characteristic of the conical surface to lock the adjusting rod 32 at the current extension length. This fine-tuning component is compact and locks securely, allowing the operator to adjust the contact pressure between the treatment head and the skin in real time during treatment or to adapt to different body contours.

[0032] It should be noted that a quick-connect device can be set on the sliding key 341 to replace manual pressing of the sliding key 341. When the sliding key 341 is pushed to the end of its stroke, the position of the sliding key 341 is locked by the quick-connect device. At this time, the fixing block 344 locks the adjusting rod 32. When it is necessary to release the adjusting rod 32, the quick-connect device can be unlocked.

[0033] In this embodiment, the treatment component 4 is connected to the front end of the adjustment rod 32 via the quick-release component 41.

[0034] like Figure 8 as well as Figure 9 As shown, the quick-release assembly 41 includes a positioning ring 411 fixed to the non-working surface of the treatment assembly 4 and at least one locking block 412, as well as a locking groove 321 opened at the end of the adjusting rod 32. The locking block 412 is connected to the positioning ring 411 by a pivot and is provided with a torsion spring to keep it inclined to open outward or close inward.

[0035] During installation, align the positioning ring 411 with the end of the adjusting rod 32. The locking block 412 will engage with the slot 321 under the action of the torsion spring, producing a "click" sound. For disassembly, press the lever (not labeled in the diagram), and refer to a conventional quick-release mechanism to disengage the locking block 412 from the slot 321, thus separating the device. This structure enables tool-free, quick replacement of the treatment head, facilitating the selection of different sizes and frequencies of treatment heads for different indications in clinical practice.

[0036] The internal structure of treatment component 4 is as follows Figure 7 As shown, it includes a housing, inside which is a composite ultrasonic transducer array. The array is divided into a central effect region 46, an intermediate effect region 47, and an outer effect region 48 from the center outwards. Each region is separated by a silicone insulating layer 42 to prevent acoustic crosstalk.

[0037] Each effect zone is led out by an independent pair of positive and negative electrodes and connected to the multi-effect synergistic control module. In a typical configuration, the central effect zone 46 is driven by a low-frequency continuous wave, such as 0.5–1.5 MHz, primarily generating thermal effects; the intermediate effect zone 47 is driven by a medium-frequency pulse wave, such as 1–2 MHz, primarily generating mechanical effects such as micro-vibrations and shear forces; and the outer effect zone 48 is driven by a higher-frequency short pulse, such as 3–5 MHz, primarily generating cavitation effects. Of course, the frequency and waveform of each zone can be reconfigured according to different treatment targets.

[0038] The working surface of the treatment component 4 is covered with a flexible coupling layer 44, such as medical silicone or hydrogel, to ensure good acoustic matching with the skin. A cooling chamber 43 is provided inside the housing, surrounding the transducer array. The cooling chamber is provided with a fluid exchange opening 45, which can circulate coolant such as sterile water at 15-25°C through an external peristaltic pump to effectively remove the heat generated by the transducer during operation and prevent the treatment head surface temperature from being too high and burning the skin.

[0039] like Figure 2 and Figure 7 As shown, a pressure sensor 5 is embedded in the working surface or inside the treatment component 4, and this sensor is electrically connected to the multi-effect collaborative control module. A ring-shaped indicator light 33 is provided on the housing 31 of the handle component 3. The color or flashing frequency of the indicator light is controlled by the multi-effect collaborative control module. When the operator places the treatment head against the patient's skin, the pressure sensor 5 detects the contact pressure in real time. The multi-effect collaborative control module drives the indicator light 33 to display different colors according to a preset pressure threshold, such as a suitable range, from light to moderate pressure: red indicates poor coupling due to insufficient pressure, green indicates optimal working condition due to moderate pressure, and yellow or orange flashing indicates excessive pressure to remind the operator to reduce the pressure. This feedback mechanism helps the operator maintain stable and effective coupling pressure, improving the safety and consistency of the treatment.

[0040] The following section uses the treatment of chronic soft tissue adhesions as an example to explain in detail the method of using the above-mentioned device for multi-effect synergistic treatment.

[0041] S1: Install the selected treatment component 4 onto the handle component 3 using the quick-release component 41, and then insert the quick-connect plug of the handle component 3 into the socket 2 of the main unit 1. Turn on the main unit, select "Multi-effect Synergistic Mode" on the smart touch screen, and set the total treatment time, for example, 15-30 minutes. The operator holds the handle component 3 and places the working surface of the treatment component 4 against the patient's painful or adhesive area, while observing the indicator light 33: gently press until the green light illuminates, indicating that the pressure has entered the preset appropriate range. If it is necessary to fine-tune the contact pressure between the treatment head and the skin, the sliding key 341 can be moved to appropriately change the extension length of the adjustment rod 32, thereby adjusting the contact pressure.

[0042] S2: After pressing the start button, the multi-effect synergistic control module first drives the central effect zone 46 to output continuous ultrasound waves, with the power gradually increasing from small to large to the set value, to slowly and evenly preheat the deep tissues.

[0043] The main purpose of the preheating phase is to raise the temperature of the target tissue to a physiologically warm state of approximately 40–42°C, softening collagen fibers, dilating capillaries, and increasing local blood flow, thus creating favorable tissue conditions for subsequent mechanical and cavitation effects. This phase lasts for several minutes, with the specific duration automatically calculated by the system or set by the physician's experience based on the lesion depth and treatment area.

[0044] S3: When the tissue temperature reaches the preset threshold, the multi-effect synergistic control module automatically activates the intermediate effect zone 47 and outputs pulsed ultrasound, while appropriately reducing the power of the central effect zone 46 to maintain a stable temperature.

[0045] The mechanical effects generated by pulsed ultrasound include minute acoustic streams and particle vibrations, which can apply shear and tensile forces to preheated and softened adhesions, gradually loosening abnormal adhesions between fascia, tendons, or ligaments. Simultaneously, it can enhance cell membrane permeability, promoting the transmembrane transport of drugs or metabolites. The intensity of the mechanical effects is controlled by adjusting the pulse duty cycle and output power to avoid overstimulation.

[0046] S4: After the mechanical effect has been applied for a period of time, such as 5 to 10 minutes, the multi-effect synergistic control module further activates the outer effect zone 48 and outputs high-frequency pulse ultrasound to induce a stable transient cavitation effect in the lesion area.

[0047] Cavitation bubbles expand during the negative pressure phase and collapse rapidly during the positive pressure phase, generating microjets and shock waves. These microjets can further pulverize loosened tissue fragments, clear blocked lymphatic vessels or microvessels, and accelerate the absorption of local edema and inflammatory products. The intensity of the cavitation effect is controlled by adjusting the ultrasound frequency and pulse repetition frequency to ensure that the cavitation activity is confined to the target area without damaging surrounding healthy tissue.

[0048] S5: Throughout the treatment process, the multi-effect synergistic control module monitors the feedback value of pressure sensor 5 and the temperature sensor inside the treatment head in real time (not specifically shown in the diagram, but data from conventional technology). If the operator accidentally changes the application pressure, causing the indicator light to turn red, the system will automatically reduce the output power of each effect zone or pause the output, and issue an audible alert. It will automatically resume operation once the pressure returns to normal. If the surface temperature of the treatment head exceeds the safe upper limit, the system will activate the coolant circulation pump, injecting coolant into the cooling chamber 43 through the coolant exchange opening 45 to quickly reduce the temperature.

[0049] Meanwhile, the control module can dynamically adjust the timing and intensity ratio of each effect zone according to the preset coordination strategy. For example, when the cavitation effect generates more heat, the output of the central effect zone can be appropriately reduced; or when the patient feels overstimulated, the power of a certain effect zone can be manually reduced.

[0050] S6: After the set total treatment time is reached, the multi-effect synergistic control module sequentially shuts down the output of each effect zone in the order of cavitation effect → mechanical effect → thermal effect to prevent discomfort caused by sudden stoppage. Finally, the main unit emits a beep, and indicator light 33 flashes to indicate that the treatment is complete. The operator removes the treatment head from the skin, presses the sliding key 341 to unlock, retracts the adjustment lever 32 to the initial position, and then presses the lever of the quick-release assembly 41 to remove the treatment head for cleaning and disinfection.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
