Detailed Description
Currently, ultrasonic technology is applied to stimulate human tissues and produce several effects to cause the change of pathological tissues, thereby achieving the purpose of treatment. The effects produced by these ultrasounds are mainly thermal, mechanical and cavitation effects.
In the stimulation mechanism of thermal effect, during the propagation of ultrasonic wave, part of the sound energy is absorbed by the medium due to the viscosity, thermal conductivity and the like of the medium, and is converted into heat energy, and the local temperature is raised. When the tissue is subjected to such a thermal effect, certain reactions occur, such as vasodilatation, increased blood circulation, and increased tissue metabolism, thereby promoting the absorption and dissipation of pathological products.
In the stimulation mechanism of the mechanical effect, the mechanical effect of particle vibration in the medium causes the vibration of acceleration, rotation, impulse flow and the like of certain fine tissues in the transmission process of the ultrasonic wave, thereby playing a role of massage, enhancing the dispersion of the semipermeable membrane (namely enhancing the permeability), the metabolic function of cells and the vitality of the cells, and generating better influence on the material exchange of the cells and the tissue nutrition.
In the stimulation mechanism of cavitation effect, when the ultrasonic wave is transmitted and meets certain liquid tissues in a human body with enough ultrasonic intensity, cavitation is generated, micro shock waves with high intensity can be generated, and pathological change tissues can be changed or damaged, so that the treatment purpose is achieved.

Fig. 1 is a schematic structural diagram illustrating an example of a head-mounted ultrasonic neurostimulation device according to an embodiment of the present application.
As shown in fig. 1, the head-mounted ultrasonic nerve stimulation device 100 includes a head-mounted bracket 110, a connection structure 120, and an ultrasonic transducer 130.
In particular, the head mount 110 may be worn on the head by the wearer and may be of various head-fitting configurations, such as a semi-toroidal support or a toroidal support, among others.
In some examples of embodiments of the present application, ultrasound transducer 130 may integrate ultrasound generation functionality such that a driving signal (electrical signal) can be independently and autonomously generated at ultrasound transducer 130 and a corresponding ultrasound neurostimulation signal (acoustic signal) is output. In other examples of embodiments of the present application, the ultrasonic transducer 130 may be electrically connected to an ultrasonic generator (also referred to as an ultrasonic driving power supply), which may convert the commercial power into a high-frequency alternating current signal (e.g., an ultrasonic electrical signal of various parameter types) matched with the ultrasonic transducer to drive the ultrasonic transducer to operate. Further, the ultrasonic transducer may output a corresponding ultrasonic nerve stimulation signal (acoustic signal) according to the driving signal generated by the ultrasonic generator.
The connection structure 120 connects the head mount 110 and the ultrasonic transducer 130, and the relative position between the head mount 110 and the ultrasonic transducer 130 can be adjusted by the connection structure 120. It should be understood that the adjustment direction with respect to the relative position may be restrictive or varied (e.g., adjustable in any angular direction with respect to the headset mount 110).
In some application scenes, when a wearer uses the head-wearing type ultrasonic nerve stimulation device, the wearer does not need to lie down and only needs to wear the head-wearing support like a hat, the operation is very convenient, and the wearer has a large free activity space. In addition, the relative position between the head-mounted support and the ultrasonic transducer can be adjusted through the connecting structure, so that the ultrasonic transducer can have more action positions, and the operation error can be reduced.
It is noted that herein, the "wearer" or "user" of the head-mounted ultrasound neurostimulation device or system may be a variety of identities, such as a doctor, a patient, etc. The terms "doctor" and "patient" as referred to elsewhere herein are used as examples only and are not intended to be limiting as to the identity of the wearer, e.g., in some cases the wearer may wear a head-mounted ultrasound neurostimulation device to perform the stimulation operation on himself, when the wearer is both a doctor and a patient.
Fig. 2 shows a schematic structural diagram of an example of a head-mounted ultrasonic neurostimulation device according to an embodiment of the application.
In some examples of embodiments of the present application, the headgear 110 is a retractable headgear. Therefore, the head-mounted bracket can be adapted to the sizes of the heads of different wearers, and the application range of the head-mounted ultrasonic nerve stimulation device is expanded. In addition, in order to increase comfort, a soft material such as sponge may be applied to the inner surface of the head mount 110 (which may be made of metal or carbon material, etc.) to protect the scalp and reduce additional injuries.
In connection with the example in fig. 2, the headgear support 110 may include an annular headband 14, a headband intersection 15, a fastener 16 (preferably a screw), and an auxiliary support 17. Specifically, the annular head band 14 may be divided into a front head band portion and a rear head band portion, which are connected by a head band intersecting portion 15 and have an overlapping area, and the head band size may be adjusted by the head band intersecting portion 15, for example, if the area where the front head band portion and the rear head band portion overlap is larger, the head band is smaller. Furthermore, after the size of the head ring is adjusted, the head ring can be screwed by the fixing member 16, so that the head ring can be adapted to different head sizes. Thus, the head mount 110 is similar to a hat, can be worn on the head, and can be appropriately sized according to the size of the head so as to be completely fitted to the head of the wearer. The head band is worn on the head, so that the ultrasonic transducer and a wearer can be integrated into a whole, and the whole process does not restrict the movement freedom of the wearer when the ultrasonic stimulation is carried out on nerves (for example, peripheral nerves).
In some examples of embodiments of the present application, a predetermined number of auxiliary supports for contacting a head of a wearer of the headgear are provided at an inner loop of the headgear. Thereby, the auxiliary support can also be used for auxiliary supporting and fixing of the head-mounted ultrasonic nerve stimulation device, so that the head-mounted ultrasonic nerve stimulation device can be reliably and stably fixed on the head of a wearer (such as a patient) wearing the head-mounted bracket.
In connection with the example in fig. 2, the head loop is assisted in completing the head loop fixing operation by the auxiliary support member 17, and the auxiliary support member 17 may be an elastic band which helps to bear a part of the weight of the entire apparatus and cushions the head loop from pressing against the head.
Further, the head-mounted ultrasound neurostimulation device may comprise an electrode array which is arranged in a preset number of auxiliary supports and by which physiological feedback signals of a wearer (e.g. a patient) of the head-mounted support may be acquired. Therefore, compared with the method that a doctor is required to sequentially attach a plurality of electrode devices (or electrode plates) to the head of a patient at present, the user only needs to wear the head frame in the embodiment of the application, and the acquisition process of stimulation effect data of the head-mounted ultrasonic nerve stimulation device is simplified. In some embodiments, the auxiliary support may be made of elastic material such as rubber, so that the auxiliary support has elasticity and can assist in bearing a part of the weight of the whole device, and the pressure of the head-mounted support on the head is buffered.
In connection with the example of fig. 2, an electrode device may be mounted on (e.g., each of) the auxiliary support 17, and since the auxiliary support is elastic so that the auxiliary support can be brought into close contact with the head, the electrode device may effectively sense signals of brain waves to capture variations of various feedback signals (e.g., brain wave signals) by the electrode device, so as to facilitate analysis of neurostimulation effects.
It should be noted that, the type of the physiological feedback signal and the arrangement of the electrode devices in the electrode device array should not be limited herein, and may be determined according to the stimulation effect data. For example, after the ultrasonic transducer outputs the ultrasonic nerve stimulation signal, the change of various feedback signals (e.g., brain wave signals) can be collected through the electrode device array, and the nerve stimulation effect can be analyzed according to the change of the feedback signals. Therefore, the electrode device is placed on the fixing strip, the electrode device is prevented from being additionally manually pasted on the head, and human errors can be reduced.
In one example of an embodiment of the present application, the connection structure is a connection structure having a fixed length between a headset and the ultrasound transducer. In another example of an embodiment of the present application, the connection structure is a telescoping connection structure, whereby the relative position between the headset and the ultrasound transducer can be adjusted along the direction of the connection structure.
In some examples of embodiments of the present application, the connection structure includes a connection rod, and a first connection member and a second connection member provided to the connection rod. Here, the position of the head mount relative to the connecting bar may be adjusted by the first connecting member, and the position of the ultrasonic transducer relative to the connecting bar may be adjusted by the second connecting member. Therefore, the relative position between the head-mounted support and the ultrasonic transducer can be adjusted by adjusting the connecting piece on the connecting rod, so that the ultrasonic transducer has a larger operating position range.
In connection with the example in fig. 2, the connecting rod may comprise a fixing rod 2, a support rod 3 and a fixing member 4 (preferably a screw), so that the connecting rod has a telescopic function. Here, the fixing rod 2 may be a tubular hollow structure, and the fixing rod 2 is sleeved outside the supporting rod 3 such that the supporting rod 3 can slide or stretch up and down inside the fixing rod 2, and the fixing rod 3 can be pressed by the fixing member 4 through a hole (not shown) in the fixing rod 2, thereby adjusting the relative position between the head coil and the ultrasonic transducer in the direction of the connecting rod. In addition, the support rod 3 can also rotate within a range of 360 degrees. Preferably, the surface of the support rod 3 is frosted or provided with concave and convex points so that the fixing member 4 can more firmly fix the support rod 3. In some embodiments, the fixing rod 2 and the supporting rod 3 may be made of metal or carbon fiber.
In some examples of embodiments of the present application, the first connector comprises a clamp for clamping the headgear. Therefore, different parts of the head-mounted support can be clamped (for example, clamped by sliding displacement) through the clamp, and diversified head-mounted support wearing modes are realized.
In connection with the example in fig. 2, the first connecting member may include a fixing clip 1, and the fixing clip 1 may fix (or clamp) the head loop, while the fixing clip 1 may move (e.g., slide) on the head loop according to actual requirements to clamp different positions of the head mount 110. In some embodiments, the fixing clip 1 may be made of metal or carbon fiber.
In some examples of embodiments of the present application, the second connector may include an ultrasound transducer fixing module for telescopically adjusting a position of the ultrasound transducer. Therefore, the ultrasonic transducer with a larger position range can be realized, and the ultrasonic transducer is favorably positioned to a required precise position.
Furthermore, a ball shaft module can be further arranged in the second connecting piece and used for fixing the ultrasonic transducer fixing module, so that the ultrasonic transducer fixing module can be driven by the ball shaft module to rotate. Here, the ball axle module has a free rotation function, so that the ultrasonic transducer fixing module can be driven by the ball axle module to rotate, and the ball axle module can adopt diversified structures, for example, a ball axle structure in a current vehicle-mounted mobile phone support can be adopted, which should not be limited herein. Therefore, the ultrasonic transducer fixing module in more directions can be realized in a ball shaft connection mode, and the ultrasonic transducer can be positioned to a required accurate position more conveniently.
In connection with the example in fig. 2, the second connection may comprise an inner movable ball 5, an outer fixed ball 6, a fixed ring 7, a fixture 8 (preferably a screw) and an ultrasound transducer fixing module 9. The ultrasonic transducer fixing module 9 may fix the ultrasonic transducer 130, and the ultrasonic transducer 130 may be made of a piezoelectric material or a flexible transducer material. In some examples of the embodiments of the present application, as shown in fig. 3A and 3B, the ultrasound transducer fixing module 9 can extend and contract the sliding ring 10 according to actual needs to adjust the far and near positions of the ultrasound transducer 130. In the state of the ultrasound transducer fixing module 9 of fig. 3A, the slide ring 10 is extended to realize the ultrasound transducer 130 in the farther position, and in the state of the ultrasound transducer fixing module 9 of fig. 3B, the slide ring 10 is contracted to realize the ultrasound transducer 130 in the closer position. Therefore, the ultrasonic transducer fixing module 9 can fix the ultrasonic transducer, is convenient to operate, can utilize the sliding ring to telescopically adjust the position of the transducer, and can stimulate nerves more accurately and individually. In some embodiments, the ultrasonic transducer fixing module may be made of metal or carbon fiber.
Specifically, the movable ball pivot (or, the ball pivot module) includes an inner movable ball 5, an outer fixed ball 6, and a fixing member 8 (preferably, a screw), the spherical surface of the inner movable ball 5 is in contact with the spherical surface of the outer fixed ball 6, and the inner movable ball 5 can be rotated with respect to the outer fixed ball 6, and the outer fixed ball 6 is tightened by rotating the fixing member 8 when adjusted to a proper direction, thereby fixing the position of the inner movable ball 5, and the spherical surface of the inner movable ball 5 is connected to the ultrasonic transducer fixing module 9. Therefore, the ball shaft is connected with the ultrasonic transducer fixing module 9, and the direction of the ultrasonic transducer can be adjusted in multiple angles and multiple dimensions. In some embodiments, the outer surface of the inner movable ball 5 and the inner surface of the outer fixed ball 6 are frosted or provided with concave-convex points for the construction of the movable ball shaft, which can increase the friction force of the two balls and facilitate the fixing of the movable ball shaft at any position. In addition, the outer fixed ball 6 may have certain elasticity, the inner diameter may be reduced by the fixed ring 7 and the fixed member 8, and the outer movable ball may be a solid ball and may be made of metal or carbon fiber.
In the head-mounted ultrasonic nerve stimulation device that this application embodiment provided, utilize can slide from top to bottom and can rotate 360 bracing piece, multi-angle rotating's movable ball axle and slip ring to realize that ultrasonic transducer can be in almost arbitrary position's multi-angle and the ascending accommodation process of multidimension degree direction, can also simply nimble and accurately operate ultrasonic transducer's position, realized collecting portablely, amazing and feeding back in function of an organic whole.
It is to be understood that the type of the term "nerve" described herein may be non-limiting and may be a variety of nerves capable of acting through ultrasound techniques, such as peripheral nerves (including facial nerves, cervical vagus nerves, etc.) or central nerves, etc. By way of example, when the non-invasive ultrasound medical technology is applied to peripheral nerves, which are closely related to organ functions and diseases, the treatment process for some diseases can achieve better clinical effects, and the peripheral nerves regulated by ultrasound can effectively intervene in diseases such as inflammation, hypertension, diabetes, obesity, and gastrointestinal tract.
Fig. 4 shows a block diagram of an example of a head-mounted ultrasound neurostimulation system according to an embodiment of the present application.
As shown in fig. 4, the head-mounted ultrasonic neurostimulation system 400 comprises the head-mounted ultrasonic neurostimulation device 100 and a display 420. Specifically, the head-mounted ultrasound neurostimulation device 100 comprises the head-mounted bracket 110, the ultrasound transducer 130 and the connecting structure 120 connecting the head-mounted bracket 110 and the ultrasound transducer 130, so that a wearer can receive an ultrasound non-invasive treatment process like wearing a hat, and the medical experience of ultrasound stimulation can be improved.
Specifically, ultrasound transducer 130 may acquire neuro-image information, display 420 may display the neuro-image information, and ultrasound transducer 130 may also output ultrasound neuro-stimulation signals.
In the embodiment of the present application, the ultrasonic transducer may be of various types, and may perform different operation processes according to driving signals of different operating parameters (for example, power, frequency, waveform, and the like for defining an ultrasonic signal), for example, an image detection function (or an ultrasonic diagnostic function) is performed based on some driving signals (for example, a first driving signal), and a modulation stimulation function is performed by some driving signals (for example, a second driving signal).
In some application scenarios of the embodiments of the present application, after the patient wears the head-mounted support, the doctor can see the neural image information on the display through the ultrasound transducer in the first working mode (e.g., under the action of the first driving signal), and can clearly see the specific position of the target point on the display, thereby facilitating accurate stimulation of the ultrasound transducer in the second working mode (e.g., under the action of the second driving signal).
In some examples of embodiments of the present application, the head-mounted ultrasonic neurostimulation system 400 may further include an ultrasonic generator 430 electrically connected to the ultrasonic transducer 130. Specifically, the ultrasonic generator 430 may generate a driving signal (e.g., corresponding to various operating parameter types of ultrasonic waves), and the ultrasonic transducer 130 may perform a corresponding functional operation, such as an ultrasonic detection function or an ultrasonic stimulation function, according to the driving signal input by the ultrasonic generator 430. Specifically, the ultrasonic transducer 130 may collect nerve image information according to the first driving signal generated by the ultrasonic generator, for example, probe a specific position of a peripheral nerve such as a subcutaneous nerve and a vagus nerve, and output an ultrasonic nerve stimulation signal according to the second driving signal generated by the ultrasonic generator, so as to achieve the effect of accurately positioning a target.
In some examples of embodiments of the present application, the ultrasound generator may receive a user operation to update the driving signal in a preset driving signal set, the preset driving signal set including the first driving signal and the second driving signal. Thereby, switching the ultrasonic detection and ultrasonic stimulation functions can be achieved by user operation for the ultrasonic generator. In other examples of embodiments of the present application, the functionality of the ultrasound generator (i.e., the functionality of generating the drive signal for the ultrasound transducer) is integrated into the ultrasound transducer, and the switching of the ultrasound detection functionality and the ultrasound stimulation functionality may be achieved by operating the ultrasound transducer.
In some examples of embodiments of the present application, the headgear is further provided with a preset number of auxiliary supports (e.g., 17 in fig. 2) for contacting with the head of the wearer of the headgear, and an electrode array (e.g., 18 in fig. 2) is provided in the preset number of auxiliary supports to acquire physiological feedback signals (or brain wave signals) of the wearer of the headgear. Further, the display 420 may display a feedback result corresponding to the physiological feedback signal. As an example, the electrode device array is connected to a receiver (a mobile terminal such as a computer, a special device, etc.) through a signal transmission cable 19, and after feedback results are obtained by operations such as signal filtering and conversion, the corresponding feedback results are displayed on a display of the receiver. Therefore, when the nerve (for example, the peripheral nerve) is stimulated, the operator can check the effect of the nerve stimulation (for example, the effect of the peripheral nerve regulated and controlled by the ultrasonic waves) in real time through the display, so that the stimulation scheme can be corrected in time, and the high-quality nerve stimulation process can be guaranteed.
It should be noted that, in addition to using the signals collected by the electrode array as feedback signals, various types of feedback signals can be captured in various ways, so that the operator can view and evaluate the effect of the neural stimulation in real time, such as signals of myoelectricity, eye movement, and brain CT (Computed Tomography), MR (Magnetic Resonance) imaging, and the like.
Through this application embodiment, a wear portable supersound stimulation nerve and brain wave feedback system is provided, possess and have not creating, safe, accurate advantage, can satisfy the demand that individualized supersound does not have the treatment of creating and operates. It is understood that due to the non-invasive nature of ultrasound stimulation, ultrasound energy applies peripheral nerve stimulation of different organs (e.g., heart, spleen, liver, pancreas, gall bladder, etc.) and can intervene in the associated disease by stimulating different organ targets. In addition, the neural stimulation device in this application embodiment is the wear-type, and the use is simple, convenient for the person that is stimulated can the free activity, and can be more quick, accurate and individuation stimulation target point (promptly, neural position), makes when increasing compliance, can also improve the efficiency and the success rate of ultrasonic stimulation peripheral nerve.
