Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic pain treatment devices, and more particularly to an ultrasonic massage probe for pain treatment and a pain treatment device. Background Art

[0002] Existing ultrasonic massage devices on the market use ultrasonic waves to massage human tissues. The principle of using ultrasonic waves to treat and relieve pain mainly utilizes the physical effects of ultrasonic waves. The physical effects include mechanical effects and thermal effects. The mechanical effect means that when ultrasonic waves propagate in a medium (such as human tissues), it will cause tiny vibrations of tissue molecules, and this vibration is called the mechanical effect. The mechanical effect can change the permeability of cell membranes, stimulate the diffusion process of the cell semi-permeable membrane, thereby promoting metabolism. The vibration of ultrasonic waves can also accelerate blood and lymph circulation, improve the ischemic and anoxic state of cells, and enhance the regeneration function. Under the action of the mechanical effect, hard connective tissues can be extended and softened, thus reducing pain. The thermal effect means that when ultrasonic waves propagate in the human body or other transmitters, heat will be generated, causing the local tissue temperature to rise. The thermal effect can dilate blood vessels, increase blood flow, improve local tissue nutrition, and enhance the activity of enzymes. At the same time, the thermal effect can also reduce the tension of muscles and connective tissues, relieve spasms and reduce pain.

[0003] The problem with existing ultrasonic massage devices is that they can only generally act on the painful parts of the human body and cannot accurately act on the tissues at the painful sites. Based on the above situation, it is necessary to design an ultrasonic massage probe for pain treatment and a pain treatment device to solve the above problems. Summary of the Invention

[0004] The present invention provides an ultrasonic massage probe for pain treatment and a pain treatment device. By transforming the existing ultrasonic massage device, it can detect the specific location of the patient's pain during ultrasonic massage, so as to more accurately perform ultrasonic massage on the painful part and improve the effect of ultrasonic massage in treating pain.

[0005] The technical problems solved by the present invention are achieved by the following technical solutions:

[0006] On the one hand, the present invention provides an ultrasonic massage probe for pain treatment, which includes a handle part and an ultrasonic massage module at one end of the handle part for treating human pain. The other end of the handle part has an ultrasonic imaging module for positioning the pain site inside the human body. The end of the handle part fixed to the ultrasonic imaging module is the first handle part, and the end fixed to the ultrasonic massage module is the second handle part. The first handle part and the second handle part are detachably connected, and an electrical plug connector is also provided at the detachable connection position of the first handle part and the second handle part. When the first handle part and the second handle part are separated, the electrical plug connector is disconnected, and when the first handle part and the second handle part are separated, the electrical plug connector is connected.

[0007] Preferably, the first handle part and the second handle part are detachably plugged and connected by a buckle.

[0008] Preferably, a guiding convex part is provided at the detachable connection end position of the first handle part, a guiding notch is provided at the detachable connection end position of the second handle part, a plug end of the electrical plug connector is provided on the guiding convex part, and a socket end of the electrical plug connector is provided inside the guiding notch. When the first handle part and the second handle part are connected, the plug end and the socket end are aligned and plugged through the guiding of the guiding convex part and the guiding notch.

[0009] Preferably, a temperature sensor is further provided inside the ultrasonic massage module for monitoring the temperature of the massage position of the human body during ultrasonic massage.

[0010] On the other hand, the present invention also provides a pain treatment device for pain treatment, which includes a host device with a touch display screen. The host device is connected to the ultrasonic massage probe for pain treatment described in any one of the above through a bus cable. The host device sends a control signal through the bus cable to control the operation of the ultrasonic massage probe and receives the signal fed back by the ultrasonic massage probe through the bus cable.

[0011] Preferably, the host device generates an ultrasonic wave signal by applying a voltage to the piezoelectric crystal inside the control ultrasonic imaging module to cause it to deform. After the ultrasonic wave signal is reflected by the human body, it is received by the piezoelectric crystal, causing the piezoelectric crystal to deform and generate an electrical signal. The host device processes the electrical signal generated by the piezoelectric crystal to obtain an internal image of the human tissue and displays it on the touch display screen.

[0012] Preferably, the host device controls the ultrasonic oscillator inside the ultrasonic massage module to vibrate to generate ultrasonic waves, and the ultrasonic waves act on the human body to treat the pain site.

[0013] Preferably, an alarm module is also provided inside the host device. The input end of the host device is also connected to the output end of the temperature sensor inside the ultrasonic massage module for receiving the temperature signal monitored by the temperature sensor. When the temperature sensor reaches the set value, the host device controls the alarm module to perform an alarm operation.

[0014] The beneficial effects of the present invention are as follows: By improving the existing ultrasonic massage probe, an ultrasonic imaging module is provided inside it, which is used to image the internal tissues of the human body when treating pain in the human body, so as to facilitate accurate positioning of the pain location.

[0015] The ultrasonic imaging module and the ultrasonic massage module are detachably connected through a handle, which can facilitate the replacement of different ultrasonic massage modules for treatment during ultrasonic treatment, so as to be applicable to different positions of the human body.

[0016] A temperature sensor is provided inside the ultrasonic massage module, which can prevent the temperature of the human body from rising too high under the action of ultrasonic massage and causing damage to the human body. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0029] In order to enable those skilled in the art to know the innovative points of the present invention, first, the prior art part related to the present invention will be introduced. The existing device for pain treatment using ultrasound includes a host device 1 with a display screen and an ultrasonic massage probe that can be controlled by the host device 1. The host device 1 powers the ultrasonic oscillator 3041 inside the ultrasonic massage probe, so that the ultrasonic oscillator 3041 emits ultrasonic waves. Attaching the ultrasonic massage probe to the skin surface of the human body can achieve the massage effect on the human body. The ultrasonic massage effect has good penetration, can drive the deep tissues to perform tiny vibrations, promote the metabolism of tissue cells, and the vibration can also accelerate blood and lymph circulation, improve the ischemic and hypoxic state of cells, and improve the regeneration function. Under the action of the mechanical effect, the hard connective tissue can be extended and softened, thereby reducing pain. At the same time, when the tissue cells are vibrating, a thermal effect will also be generated due to friction. The thermal effect can dilate blood vessels, increase blood flow, improve local tissue nutrition, enhance the activity of enzymes. At the same time, the thermal effect can also reduce the tension of muscles and connective tissues, relieve spasm and reduce pain. The above is the principle of the existing pain treatment using ultrasound.

[0030] The existing ultrasonic pain treatment device has the problem that during the ultrasonic treatment process, it can only roughly know the pain location, cannot achieve ultrasonic treatment at the precise location, and cannot view the tissue condition of the pain location during the treatment. Based on the above situation, the present invention improves the prior art to overcome the above problems.

[0031] First, the present invention provides an ultrasonic massage probe. The difference between it and the ultrasonic massage probes of the prior art is that in addition to the ultrasonic massage module 304 capable of massaging human tissues on the handle portion of the ultrasonic massage probe 3 of the present invention, there is also an ultrasonic imaging module 303 capable of positioning human tissues. Specifically, refer to Figures 2 - 5 , one end of the handle portion has an ultrasonic massage module 304, and the other end has an ultrasonic imaging module 303. When treating pain in human tissues, first, one end of the ultrasonic imaging module 303 is attached to the human skin, and the ultrasonic imaging module 303 is used to observe the tissue of the pain site in the human body to find the cause of the pain site. Then, one end of the ultrasonic massage module 304 is attached to the human body to perform precise ultrasonic massage treatment on the pain site of the human body. Since existing ultrasonic massage modules usually have different-shaped ultrasonic massage modules 304 due to the size of the pain site or to better apply to tissues in different parts of the human body, in order to facilitate the replacement of ultrasonic massage modules of different shapes and sizes during the ultrasonic treatment process, the ultrasonic massage module and the ultrasonic imaging module are set to be detachably connected through the handle, that is, the ultrasonic massage module 304 and the ultrasonic imaging module 303 are respectively at both ends of the handle portion. The end of the handle portion connected to the ultrasonic imaging module 303 is the first handle portion 301, and the end of the handle portion connected to the ultrasonic massage module 304 is the second handle portion 302. An electrical plug-in connector is also provided at the connection position between the first handle portion 301 and the second handle portion 302. When the first handle portion 301 and the second handle portion 302 are separated, the electrical plug-in connector is disconnected, and when the first handle portion 301 and the second handle portion 302 are separated, the electrical plug-in connector is connected.

[0032] Furthermore, the first handle portion 301 and the second handle portion 302 can be detachably connected by a buckle. As Figure 4 and Figure 5 shown, a reed buckle body 309 is provided on the first handle portion 301, and a slot 310 with a buckle hole on its side wall is provided on the second handle portion 302. The end of the reed buckle body 309 has a claw that can be hooked in the buckle hole to realize the connection between the first handle portion 301 and the second handle portion 302. This buckle connection is very common in daily life, and those skilled in the art can easily understand it through the drawings, so the specific process of its use will not be elaborated in detail here. This buckle connection has the advantages of being easy to disassemble and capable of quick installation.

[0033] Further, to ensure that when the first handle portion 301 and the second handle portion 302 are connected, the electrical plug connector can be stably aligned to achieve reliable electrical connection, a guiding convex portion 305 is provided at the detachable connection end position of the first handle portion 301, a guiding notch 307 is provided at the detachable connection end position of the second handle portion 302, a plug end 306 of the electrical plug connector is provided on the guiding convex portion 305, a socket end 308 of the electrical plug connector is provided inside the guiding notch 307. When the first handle portion 301 and the second handle portion 302 are connected, the plug end 306 and the socket end 308 are guided and aligned and inserted through the guiding convex portion 305 and the guiding notch 307, so as to achieve stable alignment.

[0034] Further, to ensure that during the ultrasonic massage treatment process, the thermal effect on human tissues is not too intense and the human tissues are damaged due to high temperature, a temperature sensor 3043 is further provided inside the ultrasonic massage module 304 to monitor the temperature of the massage position of the human body during the ultrasonic massage process.

[0035] The above is the improvement made by the present invention to the ultrasonic massage probe 3 of the existing device for pain treatment using ultrasound. The main improvement points are that by adding an ultrasonic imaging module 303 on the handle portion, image acquisition of the patient's pain site can be realized, so as to facilitate accurate treatment of the pain site. For example, Figure 8 As shown, there are multiple sizes of the ultrasonic massage module 304 connected to the second handle portion 302, all of which can be connected to the first handle portion 301 through the second handle portion 302 to adapt to different positions of the human body for treatment.

[0036] On the other hand, since the present invention adds an ultrasonic imaging module 303, on this basis, the present invention also improves the host device 1 to be able to control the ultrasonic imaging module 303 and the ultrasonic massage module 304 to work. Specifically, the present invention provides a pain treatment device, including the above-mentioned ultrasonic massage probe 3 and the host device 1. For example, Figure 1 As shown, the host device 1 is provided with a touch display screen 2. The touch display screen 2 is used to display a human-computer interaction interface, facilitating personnel to set control parameters through the touch display screen 2, and is also used to display the human tissue image obtained by the host device 1 processing the signal acquired by the ultrasonic imaging module 303. The host device 1 transmits control signals to the ultrasonic imaging module 303 and the ultrasonic massage module 304 on the handle portion through a bus cable 4. Specifically, the bus cable 4 can extend from the output end of the host device 1 into the inside of the first handle portion 301 and then be divided into two parts. One part is used to connect to the ultrasonic imaging module 303, and the other part extends to the plug end 306 of the electrical plug connector. The socket end 308 and the ultrasonic massage module 304 are also connected through a cable, thereby realizing the connection of the bus cable 4 to the ultrasonic massage module 304.

[0037] Furthermore, the specific structure of the ultrasonic imaging module 303 can be referred to Figure 6 , which includes a backing layer 3031, piezoelectric crystals 3032 (array elements), a matching layer 3033, and an acoustic lens layer 3034 (the names of the backing layer 3031, the matching layer 3033, and the acoustic lens layer 3034 are consistent with the naming of the parts of the existing ultrasonic imaging probe, and the functions of each part are not elaborated in detail here). The host device 1 energizes the piezoelectric crystals 3032, causing the piezoelectric crystals 3032 to deform (when a voltage is applied to it, it will expand; when the voltage is removed, it will contract back to its original thickness. If the voltage is repeatedly applied and removed quickly, the piezoelectric crystals 3032 will expand and relax quickly, thus generating ultrasonic waves), thereby generating ultrasonic waves. The piezoelectric crystals 3032 include a part for emitting ultrasonic waves and a part for receiving ultrasonic waves, that is, after the generated ultrasonic waves enter the human body and are reflected back, they are received by some of the piezoelectric crystals 3032. When the piezoelectric crystals 3032 are struck by the ultrasonic waves, they will deform, and after generating the deformation, an electrical signal will be generated. After the electrical signal is fed back to the host device 1, the host device 1 processes the electrical signal to obtain the corresponding human tissue image. The specific principle of this ultrasonic imaging module 303 is the same as that of the existing B-ultrasound probe, and will not be elaborated in detail here.

[0038] Furthermore, as Figure 7 , the ultrasonic massage module 304 is internally composed of multiple ultrasonic vibrators 3041. When the host device 1 supplies power to the ultrasonic vibrators 3041, the ultrasonic vibrators 3041 emit ultrasonic vibrations. It should be noted that the ultrasonic vibrators 3041 are similar in structural principle to the ultrasonic vibrators 3041 in the prior art, and its main components are composed of piezoelectric ceramic sheets, magnets, coils, etc. (prior art, the detailed structure is not shown in the figure). Among them, the piezoelectric ceramic sheet is the working part of the vibrator, responsible for converting electrical energy into mechanical energy. The magnet and the coil form an electromagnetic field, and the vibration amplitude and frequency of the piezoelectric ceramic sheet are regulated by controlling the strength of the magnetic field. The ultrasonic vibrators 3041 transmit the vibration to the housing cover 3042 (the monitoring end of the temperature sensor 3043 is placed on the housing cover 3042). When the housing cover 3042 contacts the human tissue, the vibration is transmitted to the interior of the human tissue. The number of ultrasonic vibrators 3041 is not limited, and it is designed according to the shape and volume of the ultrasonic massage module 304 and the required massage intensity.

[0039] Furthermore, as Figure 9As shown in the figure, a temperature sensor 3043 is also provided inside the ultrasonic massage module 304 to monitor the temperature of human tissues during the operation of the ultrasonic module. The signal output end of the temperature sensor 3043 is connected to the signal input end of the host device 1. An alarm module is also provided on the host device 1. When the host device 1 determines through the temperature sensor 3043 that the temperature of the human body at the ultrasonic massage treatment position is too high (exceeding the previously set threshold), the host device 1 controls the alarm module to work and reminds the personnel. Specifically, the alarm module can be the speaker 5 on the host device 1, which alarms by emitting a prompt sound. At the same time, it can also be prompted by displaying text on the touch display screen 2.

[0040] For those skilled in the art to understand the working principle of the present invention in detail, as Figure 9 shown in the figure, the usage process of the pain treatment device of the present invention is described herein. First, turn on the host device 1, and the touch display screen 2 displays the operation interface. Set the control parameters for the ultrasonic imaging module 303 through the operation interface. Then, bring one end of the handle corresponding to the ultrasonic imaging module 303 into contact with the human tissue. Obtain the tissue image inside the human body through the ultrasonic imaging module 303 to locate and mark the pain site. Then, set the control parameters for the ultrasonic massage module 304 through the operation interface according to the condition of the pain site. Align the end of the handle with the ultrasonic massage module 304 to the pain-marked position to achieve precise treatment of the human pain site. After obtaining the image of the pain site inside the human body, different-sized ultrasonic massage modules 304 can also be installed to treat the pain site. During the treatment process, the temperature sensor 3043 always monitors the temperature of the epidermal tissue at the massage position to avoid damage caused by high temperature. After the massage treatment is completed, the tissue at the pain site can be observed through the ultrasonic imaging module 303 for subsequent treatment.

[0041] It should be further noted that although the basic principles of the ultrasonic imaging module 303 and the ultrasonic massage module 304 are both to achieve ultrasonic imaging and ultrasonic treatment through piezoelectric materials, there are significant differences in their structures. The operating frequency of the ultrasonic imaging device is between 2MHZ - 20MHZ (M represents 10 to the sixth power), while the operating frequency of the ultrasonic massage module 304 is between dozens of KHZ and hundreds of KHZ (K represents 10 to the third power), and there is a large difference in their operating frequencies. Secondly, the number of piezoelectric crystals (array elements) inside the ultrasonic imaging device is generally large, and common array element numbers are 32, 64, 128, 192, 256, 512, etc. Each group of array elements can independently transmit and receive ultrasonic signals and is the basic constituent unit of the ultrasonic imaging module 303. Moreover, the volume of each array element is about a few millimeters, so the amplitude of the ultrasonic vibration generated by it is not sufficient to meet the requirements of massage. While for the ultrasonic massage module 304, the piezoelectric ceramics inside generally only need to receive voltage and emit vibration, and generally do not need to perform feedback vibration. Its main function is to generate sufficient amplitude to achieve massage of the human body. Its piezoelectric ceramics are mostly made into ultrasonic vibrators 3041 with relatively large sizes. Generally, the number of ultrasonic vibrators 3041 is one or several, so that it can generate sufficient amplitude to achieve massage of the human body. During the treatment process, by adjusting the frequency of the ultrasonic vibrator 3041, the adjustment of the massage gear or working mode can be achieved. For example, during conventional massage treatment, the ultrasonic vibrator 3041 is maintained at a lower frequency of operation. When it is necessary to better transport external liquid medicine to the painful tissue part of the human body, by increasing the vibration frequency of the ultrasonic vibrator 3041, the liquid medicine can be better atomized and enter the human tissue.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
