Description

Handheld ultrasonic treatment head TECHNICAL FIELD

[0001] The present disclosure relates to the field of ultrasonic treatment, in particular to a handheld ultrasonic treatment head. BACKGROUND

[0002] The method of applying ultrasonic waves to the human body to achieve therapeutic purposes is called ultrasonic treatment. The use of ultrasonic treatment is increasingly widespread, far beyond the general therapy of physiotherapy department, such as ultrasonic treatment of cancer, urinary system lithotripsy and application of oral medicine, etc. When ultrasonic waves propagate in human tissues, mechanical, thermal and cavitation effects are produced, which can achieve the purpose of treating diseases or relieving symptoms according to different biological effects.

[0003] Most of the existing ultrasonic treatment equipment adopts a fixed ultrasonic treatment head, and the existing ultrasonic treatment head is mostly provided with a water bag, resulting in a large volume and weight. Therefore, due to the large weight and volume and the limitation of the installation method, the existing fixed ultrasonic treatment head can only perform ultrasonic treatment on a specific area of the patient's body (such as the chest and abdomen) and cannot perform ultrasonic treatment on other areas (such as the side of the body when the patient is lying down and the body parts that cannot be reached). Thus, the existing ultrasonic treatment equipment has certain treatment limitations.

[0004] Therefore, the present application provides a handheld ultrasonic treatment head, mainly composed of an ultrasonic transducer, a drive control module and a connecting cable, etc. By directly acting on human tissues with ultrasonic waves, a non-invasive or non-invasive treatment effect is achieved. To solve the above problems and the problem of low ultrasonic treatment efficiency caused by the complicated operation steps and process of the existing handheld ultrasonic treatment head. SUMMARY

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the present disclosure is to provide a handheld ultrasonic treatment head to solve the problems in the related art.

[0006] The first aspect of the present disclosure provides a handheld ultrasonic treatment head, comprising:

[0007] a body;

[0011] the controller, in response to the loading signal and the firing signal, controls the driving unit to drive the ultrasonic output unit to emit ultrasonic waves.

[0012] In an embodiment of the first aspect, before the loading switch is triggered, the firing switch is in a locked state and cannot be triggered.

[0013] In an embodiment of the first aspect, before the ultrasonic output unit stops emitting ultrasonic waves, both the loading switch and the firing switch are in a continuously triggered state.

[0014] In an embodiment of the first aspect, a heartbeat protocol is established between the controller and the driving unit, and the heartbeat protocol comprises:

[0015] When the controller detects that a treatment parameter deviates from a preset safety threshold or the temperature sensor overheats, an emergency procedure is started; the controller communicates emergency braking information to the driving unit through an internal communication path, and instructs the power management unit to cut off power supply to the driving unit, to implement emergency braking of the treatment process;

[0016] When the handheld ultrasonic treatment head enters the emergency braking state, the controller does not terminate its self-checking and signal output functions, and communicates the abnormal working state of the handheld ultrasonic treatment head to the outside through at least one fault warning mechanism.

[0017] In an embodiment of the first aspect, the heartbeat protocol further comprises: when communication with the controller is interrupted or system stability is detected to be abnormal, emergency braking of the treatment process is implemented;

[0018] When the handheld ultrasonic treatment head enters the emergency braking state, the controller communicates the abnormal working state of the handheld ultrasonic treatment head to the outside through at least one fault warning mechanism.

[0019] In an embodiment of the first aspect, the control assembly further comprises an indicator light electrically connected to the controller; in response to receiving the loading signal, the controller sets the indicator light to a first color; in response to receiving the firing signal while receiving the loading signal, the indicator light displays a second color; and in response to an emission end signal of the ultrasonic waves, the indicator light displays a third color.

[0020] In an embodiment of the first aspect, the controller is communicatively connected with the ultrasonic treatment master device; and the controller is configured to perform operations comprising:

[0021] The task receiving unit acquires the treatment parameters issued by the ultrasonic treatment master device; in response to the loading switch being triggered, the loading signal output by the loading switch is received to enable the transmission switch to be in an active state; in response to the transmission switch being triggered, the transmission signal output by the transmission switch is received to enable the driving unit to drive the ultrasonic output unit to output ultrasonic waves, and the operation is stopped in response to the transmission end signal of the ultrasonic waves sent by the driving unit.

[0022] In an embodiment of the first aspect, the transmission switch is implemented as a mechanical key switch, which is fixedly arranged on the surface of the controller.

[0023] In an embodiment of the first aspect, the loading operation key is fixedly connected to the body by a first elastic member, so that the loading operation key is reset to a position away from the loading switch; and / or a second elastic member is arranged between the transmission operation key and the transmission switch, so that the transmission operation key is reset to a position away from the transmission switch.

[0024] As described above, the handheld ultrasonic treatment head in the embodiment of the present disclosure includes a body, a control assembly fixedly arranged on the body, and an ultrasonic output unit, a task receiving unit, a controller, a driving unit, a power management unit, a loading switch, and a transmitting switch. The task receiving unit is coupled to the controller. The loading switch and the transmitting switch are electrically connected to the controller. The controller is coupled to the driving unit. The driving unit is coupled to the ultrasonic output unit. The power management unit is electrically connected to the controller and the driving unit. A loading operation key is arranged. When the loading operation key is operated to trigger the loading switch, the loading switch outputs a loading signal to the controller. A transmitting operation key is arranged. When the transmitting operation key is operated to trigger the transmitting switch, the transmitting switch outputs a transmitting signal to the controller. The controller controls the driving unit to drive the ultrasonic output unit to transmit ultrasonic waves in response to the loading signal and the transmitting signal. When a user holds the handheld ultrasonic treatment head with one hand, the short stroke of the microswitch can be avoided to prevent misoperation and thus prevent errors caused by misoperation. In addition, the long stroke of the mechanical key switch can provide a better feeling of single-handed operation for the user, so as to facilitate the operation and use of the user, improve the efficiency of treatment, and reduce errors. The existing water bag design is replaced by the medium pad, so that the overall volume of the handheld ultrasonic treatment head in the embodiment of the present disclosure is small, so as to facilitate the operation and holding of the user. In addition, the user squeezes the sound transmission part, so that the gas between the medium pad and the notch and the sound transmission part can be discharged to the accommodation cavity and finally discharged to the outside through the exhaust part, so as to avoid the influence of the gas between the medium pad and the notch and the sound transmission part on the spread and reflection of ultrasonic waves, and finally cause errors in the test results.

[0045] Fig. 1 shows a schematic diagram of the overall structure of a handheld ultrasonic treatment head according to an embodiment of the present disclosure. Fig. 2 shows a schematic diagram of the overall sectional view of the handheld ultrasonic treatment head according to an embodiment of the present disclosure. Fig. 3 shows an enlarged view of A in Fig. 1. In the examples of Figs. 1, 2 and 3, the handheld ultrasonic treatment head comprises a body 10, a control assembly 20, a loading operation key 30 and a transmitting operation key 40. The control assembly 20 is fixedly connected (e.g. threaded, snap-fit) to the body 10. The control assembly 20 comprises an ultrasonic output unit 27, a task receiving unit, a controller 21, a driving unit 24, a power management unit 25, a loading switch 22 and a transmitting switch 23. The task receiving unit is coupled to the controller 21. The loading switch 22 and the transmitting switch 23 are both electrically connected to the controller 21. The controller 21 is coupled to the driving unit 24. The driving unit 24 is coupled to the ultrasonic output unit 27. The power management unit 25 is electrically connected to the controller 21 and the driving unit 24.

[0046] Exemplarily, the task receiving unit is communicatively connected to the controller 21. In some embodiments, the task receiving unit is built-in the controller 21. Or the task receiving unit is communicatively connected to an interface on the controller 21. Exemplarily, the task receiving unit can be implemented by hardware, software or a combination of hardware and software.

[0047] In the example of Fig. 2, when the loading operation key 30 is operated to actuate the loading switch 22, the loading switch 22 outputs a loading signal to the controller 21; when the transmitting operation key 40 is operated to actuate the transmitting switch 23, the transmitting switch 23 outputs a transmitting signal to the controller 21; the controller 21, in response to the loading signal and the transmitting signal, controls the driving unit 24 to drive the ultrasonic output unit 27 to emit ultrasonic waves.

[0048] Exemplarily, before the loading switch 22 is activated, the transmitting switch 23 is in a locked state in which it cannot be activated. That is, before the loading switch 22 is activated, even if the user actuates the transmitting switch 23 alone, the controller 21 will not drive the ultrasonic output unit 27 to emit ultrasonic waves according to the transmitting signal generated by the transmitting switch 23; or the transmitting switch 23 cannot generate a transmitting signal.

[0049] Exemplarily, before the ultrasonic output unit 27 stops outputting ultrasonic waves, the loading switch 22 and the transmitting switch 23 are in a continuously triggered state. Since the loading switch 22 and the transmitting switch 23 have been triggered and remain in the triggered state, even if the loading switch 22 and the transmitting switch 23 are pressed again, the corresponding signals cannot be generated again. Until the ultrasonic output unit 27 stops outputting ultrasonic waves, the loading switch 22 and the transmitting switch 23 return to the original state that can be triggered to perform the next operation.

[0050] In another embodiment, before the ultrasonic output unit 27 stops outputting ultrasonic waves, the loading switch 22 and the transmitting switch 23 are in a locked state that cannot be triggered. That is, before the ultrasonic output unit 27 stops outputting ultrasonic waves, even if the loading switch 22 and the transmitting switch 23 are triggered again, the loading switch 22 and the transmitting switch 23 cannot generate corresponding signals. Or the loading switch 22 and the transmitting switch 23 cannot be triggered.

[0051] Exemplarily, the loading operation key 30 is movably arranged along a first initial position to a first operation position. The loading operation key 30 is fixedly connected to the body 10 by a first elastic member 31. A first avoiding hole 101 is formed on the body 10, and the loading operation key 30 is embedded in the first avoiding hole 101. Exemplarily, the transmitting operation key 40 is movably arranged along a second initial position to a second operation position.

[0052] It can be understood that when the loading operation key 30 triggers the loading switch 22, the first elastic member 31 generates a reset force to return the loading operation key 30 to the first initial position. Exemplarily, the first avoiding hole 101 and the loading operation key 30 are the same shape and size, for example, circular or rectangular. Exemplarily, the first elastic member 31 is implemented as a cantilever, one end of which is fixedly connected to the body 10, and the other end is fixedly connected to the loading operation key 30. In another embodiment, the first elastic member 31 can also be implemented as a spring.

[0053] A cross-sectional view of the transmission switch 23 in the embodiment of the present disclosure is shown in FIG. 4. As shown in the example of FIG. 4, the transmission switch 23 is implemented as a mechanical key switch, and the stroke of the mechanical key switch is greater than that of a micro switch. Further, according to the information available, the total stroke of the mechanical key switch is 2-4 mm, and the stroke of the contact is 2±0.6 mm. The total stroke of the micro switch is 1-3 mm, and the stroke of the contact is 0.3±0.2 mm. Preferably, the total stroke of the mechanical key switch is 3-4 mm. Further, it can be seen from the comparison that the total stroke and the peak value of the stroke of the contact of the mechanical key switch are both greater than those of the micro switch. Therefore, the stroke of the mechanical key switch is greater than that of the micro switch. Through the above arrangement, when the user holds the handheld ultrasonic treatment head with one hand, the short stroke of the micro switch can be avoided to prevent misoperation and thus prevent errors caused by misoperation. Further, the long stroke of the mechanical key switch can provide a better feeling of one-handed operation to the user, so as to facilitate the operation and use of the user, improve the efficiency of treatment, and reduce errors. Exemplarily, the loading switch 22 is implemented as a micro switch. In another embodiment, the loading switch 22 can also be implemented as a mechanical key switch.

[0054] In the example of FIG. 2, the handheld ultrasonic treatment head includes a second elastic member 41 abutting between the transmission switch 23 and the transmission operation key 40. The second elastic member 41 can be driven (e.g., pushed by extrusion) by the movement of the transmission operation key 40 in the direction of approaching the second operation position to actuate the transmission switch 23, and deformed to form a restoring tendency of the transmission operation key 40 to the second initial position. Exemplarily, the second elastic member 41 is implemented as a spring. One end of the spring is fixedly connected to the handheld ultrasonic treatment head, the other end forms a force applying portion abutting the transmission switch 23, and a force receiving portion abutting the transmission operation key 40 is further formed between the two ends.

[0055] When the user presses the transmission operation key 40 to move the transmission operation key 40 in the direction of approaching the second operation position from the second initial position, the transmission operation key 40 applies force to the force receiving portion of the spring abutting therewith, so as to make the force applying portion of the spring actuate the transmission switch 23, and the spring is deformed in the process. When the user releases the transmission operation key 40, the spring restores to the original state due to the absence of extrusion, and in the process, the transmission operation key 40 is restored to the second initial position under the driving of the restoring force of the deformation of the spring.

[0056] In another embodiment, the second elastic member 41 can also be implemented as an elastic strip, i.e. both ends of the elastic strip in length direction are fixedly connected to the hand-held ultrasonic treatment head, and the middle part of the elastic strip abuts against the side wall of the emission operating key 40 towards the emission switch 23. In another embodiment, when the emission operating key 40 moves in the direction from the second initial position to the second operating position, the emission operating key 40 can directly press the emission switch 23, and the second elastic member 41 only plays a resetting role.

[0057] In the example of Fig. 2, the body 10 forms a second avoiding hole 102 corresponding to the position of the emission operating key 40, and the emission operating key 40 is movably combined with the second avoiding hole 102 and partially exposes the second avoiding hole 102. Exemplarily, the side wall of the emission operating key 40 which does not expose the second avoiding hole 102 is provided with a stop portion 42 stopping the emission operating key 40 from completely exposing the second avoiding hole 102. When the emission operating key 40 is in the initial position, the stop portion 42 abuts against the inner wall of the hand-held ultrasonic treatment head to stop the emission operating key 40. Exemplarily, the stop portion 42 is implemented as an annular plate with the same shape as the emission operating key 40. In another embodiment, the stop portion 42 can also be implemented as two rectangular plates symmetrically arranged. Exemplarily, the second avoiding hole 102 has the same shape and size as the emission operating key 40. For example, the emission operating key 40 is implemented as an oval, and the second avoiding hole 102 is also implemented as an oval. In another embodiment, the second avoiding hole 102 and the emission operating key 40 can also be implemented as a circle or a rectangle.

[0058] Fig. 5 is an enlarged view of B in Fig. 2. In the examples of Fig. 2 and Fig. 5, the emission operating key 40 is swingably arranged on the body 10. Exemplarily, the emission operating key 40 includes a connecting end 43 and a pressing end 44. The connecting end 43 is hingedly connected to the body 10. In this way, the pressing end 44 of the emission operating key 40 swings to make the emission operating key 40 move from the initial position to the trigger position. According to the above example implementation, the size of the avoiding hole should be larger than the size of the emission operating key 40, so that the emission operating key 40 can smoothly swing without being blocked by the hole wall of the avoiding hole. Further exemplarily, a hinge hole is formed on the hand-held ultrasonic treatment head, and the connecting end 43 is implemented as a hinge column rotatably combined in the hinge hole.

[0059] Fig. 6 shows a partial structure diagram of another embodiment of the present disclosure. In the example of Fig. 6, the firing operation key 4 is slidingly arranged on the body 10. In the example, the body 10 forms a third avoiding hole 103 corresponding to the position of the firing operation key 4, and the extending direction of the third avoiding hole 103 is the same as the direction of the firing operation key 4 moving from the first initial position to the second operation position. In the further example, the third avoiding hole 103 has the same shape and size as the firing operation key 4.

[0060] Returning to the example of Fig. 2, the second elastic member 41 keeps abutting against the firing operation key 40 when the firing operation key 40 moves back and forth between the second initial position and the second operation position. The second elastic member 41 keeps elastically deformed when the firing operation key 40 moves back and forth between the initial position and the trigger position. This avoids the firing operation key 40 being loose in the second avoiding hole 102, improves the overall quality of the handheld ultrasonic treatment head, and further improves the feeling of the user when operating, thereby improving the treatment effect and efficiency. In the example, the loading operation key 30 and the firing operation key 40 are reset to positions where the loading switch 22 and the firing switch 23 cannot be touched after being operated. This further avoids the user's misoperation.

[0061] Fig. 7 shows a circuit structure diagram of the control assembly 20 in the embodiment of the present disclosure. As shown in the examples of Figs. 1, 2 and 7, the body 10 includes a treatment end 11, and the ultrasonic output unit 27 is arranged on the treatment end 11. In the example, the ultrasonic output unit 27 is implemented as an ultrasonic transducer. The control assembly 20 further includes an indicator light 26 electrically connected to the controller 21. The controller 21 sets the indicator light 26 to a first color in response to receiving the loading signal, sets the indicator light 26 to a second color in response to receiving the firing signal while receiving the loading signal, and sets the indicator light 26 to a third color in response to an ultrasonic wave emission end signal. The indicator light 26 displays three colors during each ultrasonic wave emission, so that the operator can determine the progress of each ultrasonic wave emission by color, thereby avoiding the operator's misoperation and making the operation more simple and convenient.

[0062] In the example of FIG. 7, the treatment end 11 is further provided with a temperature detector 28 electrically connected to the controller 21 to monitor the temperature of the ultrasound output unit 27. The controller 21 is electrically connected to at least one prompter 281 which performs a prompt action when the controller 21 receives different signals. For example, the prompter 281 is implemented as a buzzer, the controller 21 buzzes once when receiving the loading signal, and the buzzer buzzes again after the loading is completed to prompt the user to continue the treatment; the controller 21 buzzes once when receiving the emitting signal, and the ultrasound output unit 27 buzzes once after the single treatment is completed to prompt the user that the next point of treatment can be performed. Illustratively, the prompter 281 can also be used in cooperation with the indicator light 26, i.e. the indicator light 26 changes a color each time, and the prompter 281 performs a prompt action at the same time. Illustratively, in another embodiment, the prompter 281 is implemented as a vibrator, and the prompt action is vibration.

[0063] Illustratively, the control assembly 20 further includes a serial port 29 electrically connected to the controller 21, and the serial port 29 is connected to an ultrasound treatment main device. Returning to the example of FIG. 1, the handheld ultrasound treatment head further includes at least one wire harness 90 electrically connected to the serial port 29. The wire harness 90 is used for transmission of power supply signals and communication signals. Those skilled in the art can understand that the wire harness 90 can be implemented as a plurality of wire harnesses 90 of different types, for example, including at least one power supply wire harness and at least one communication wire harness. In another embodiment, the wire harness 90 is implemented as a plurality of power supply wire harnesses and a plurality of communication wire harnesses. In the example of FIG. 1, the handheld ultrasound treatment head further includes a burning interface 110. To achieve writing of digital information into electronic devices, so that the handheld ultrasound treatment head can perform specific functions. Illustratively,

[0064] FIG. 8 shows an enlarged view of C in FIG. 2. In the examples of FIG. 2 and FIG. 8, the handheld ultrasound treatment head includes the body 10 and a mounting member 50. The body 10 has a mounting end 12. Illustratively, the mounting end 12 is formed at the end of the body 10 facing the patient. The mounting member 50 is fixedly connected to the body 10 and covers the mounting end 12. Illustratively, the fixed connection is implemented as at least one of insertion or screwing. In the example of FIG. 7, the fixed connection is implemented as screwing. Illustratively, the mounting member 50 is connected to the body 10 by screwing. In another embodiment, the fixed connection is implemented as insertion. Illustratively, the mounting member 50 is implemented as a cylinder to improve the aesthetics of the handheld ultrasound treatment head. In another embodiment, the mounting member 50 can also be implemented as a rectangle or an ellipse.

[0065] In the example of FIG. 8, the mounting member 50 comprises a transmitting end 51, and the transmitting end 51 is provided with a sound-transmitting portion 511. Exemplarily, the sound-transmitting portion 511 is implemented as a diaphragm. Exemplarily, the sound-transmitting portion 511 is located at the mounting end 12. The sound-transmitting portion 511, the mounting member 50 and the mounting end 12 form a containing cavity 104. The handheld ultrasonic treatment head comprises a medium pad 60 and at least one air exhaust portion 70. The medium pad 60 is arranged between the mounting end 12 and the sound-transmitting portion 511 and is in contact with the sound-transmitting portion 511. Exemplarily, the mounting end 12 comprises a concave portion facing away from the body 10. Further exemplarily, the concave portion is implemented as a circular curved concave portion. That is, one end of the medium pad 60 is in contact with the curved concave portion, and the other end is in contact with the sound-transmitting portion 511.

[0066] The at least one air exhaust portion 70 is formed on the mounting member 50, and the air exhaust portion 70 is used for connecting the containing cavity 104 with the outside. Exemplarily, the air exhaust portion 70 is formed on the side wall of the mounting member 50 at the end connected with the containing cavity 104. When the user presses the sound-transmitting portion 511, the air between the medium pad 60 and the concave portion and the sound-transmitting portion 511 can be exhausted to the containing cavity 104, and finally the air in the containing cavity 104 is exhausted to the outside through the air exhaust portion 70. In this way, the bubbles between the medium pad 60 and the concave portion and the sound-transmitting portion 511 do not affect the spread and reflection of ultrasonic waves, and finally the situation that the treatment effect is poor or the examination result is inaccurate does not occur. In another embodiment, the concave portion can also be implemented as a rectangular or elliptical shape, and the shape of the medium pad 60 is adapted to the shape of the concave portion. Exemplarily, the edge of the end of the transmitting end 51 close to the patient's skin is rounded or chamfered, so as to avoid scratching the patient during treatment.

[0067] Referring back to the example of FIG. 1, the exhaust portion 70 is implemented as a plurality of exhaust portions 70, which are spaced apart on the mounting member 50 and each of which is configured to communicate the accommodating cavity 104 with the outside. In an example, the plurality of exhaust portions 70 are spaced apart along the circumferential direction of the cylindrical mounting member 50 on the sidewall of the mounting member 50. In an example, the exhaust portion 70 is implemented as an exhaust port (e.g., a circular port or a rectangular port). In a further example, the exhaust port is provided with a filter screen (not shown in the figure) configured to prevent foreign matter from the outside from entering the accommodating cavity 104. In another example, the exhaust port is provided with a one-way valve configured to allow gas to be exhausted from the accommodating cavity 104 to the outside only. In another example, the exhaust portion 70 can also be implemented as an exhaust pipe or an exhaust hole. In another example, the exhaust portion 70 can also be implemented as one. When the exhaust portion 70 is implemented as one, the diameter of the exhaust portion 70 is implemented to be greater than the diameter of the exhaust portion 70 when the exhaust portion 70 is implemented as a plurality, so as to allow gas between the medium pad 60 and the recess and the sound-transmitting portion 511 to be smoothly exhausted to the outside.

[0068] In the example of FIG. 8, the position of the emitting end 51 facing the mounting end 12 forms a mounting hole 5101, and the diaphragm is detachably arranged on the emitting end 51 and covers the mounting hole 5101. The diaphragm is in contact with the medium pad 60. In an example, the position of the mounting hole 5101 corresponds to the mounting end 12. In an example, the diaphragm is implemented to be connected to the outer wall surface of the emitting end 51 by adhesion to cover the mounting hole 5101, so as to facilitate replacement of the diaphragm by a user at a later time. In an example, the emitting end 51 is formed with a relief groove, which is filled when the diaphragm is arranged on the emitting end 51, so that the emitting end 51 provided with the diaphragm is a plane, thereby facilitating use at a later time. In another example, the diaphragm can also be implemented to be connected to the outer wall surface of the emitting end 51 by clamping or screwing to cover the mounting hole 5101. In an example, the mounting hole 5101 is implemented as a circular hole. In another example, the mounting hole 5101 can also be implemented as a rectangular hole or an elliptical hole.

[0069] In the example of FIG. 8, the sound-transmitting part 511 is a deformable body that deforms and presses the medium pad 60 under the action of an external force. Illustratively, the sound-transmitting part 511 is implemented as an ultrasonic coupling film to isolate the medium pad 60 from the skin of the patient. Illustratively, the medium pad 60 is implemented as an aqueous polymer gel. In another embodiment, the medium pad 60 can also be implemented from other materials that can reduce the loss of reflection of ultrasonic waves. Secondly, the pressing of the sound-transmitting part 511 against the medium pad 60 is used to expel the gas therebetween to the accommodating cavity 104 and eventually to the outside through the exhaust part 70. Illustratively, the film is implemented from a transparent material to facilitate the user to observe and determine whether there is a bubble between the sound-transmitting part 511 and the medium pad 60, so that the user can implement the above-mentioned pressing action in the area where there is a bubble to expel the gas therebetween to the accommodating cavity 104 and eventually to the outside through the exhaust part 70. In another embodiment, the sound-transmitting part 511 can also be implemented from other materials that can facilitate the user to observe and determine whether there is a bubble between the sound-transmitting part 511 and the medium pad 60.

[0070] Illustratively, the medium pad 60 is sized to fit the mounting hole 5101. In the example of FIG. 8, one end of the medium pad 60 is in contact with the notch, and the other end of the medium pad 60 extends out of the mounting hole 5101 and is in contact with the sound-transmitting part 511. At this time, the end of the medium pad 60 close to the skin of the patient is in contact with the hole wall of the mounting hole 5101 and is limited within the mounting hole 5101 to stop the medium pad 60 from being offset within the mounting hole 5101. The other end is in contact with the notch and is limited in the mounting end 12 due to the support of the mounting end 12. Thus, the medium pad 60 can be effectively prevented from being offset due to the sliding of the sound-transmitting part 511 on the skin of the patient, and further, the situation of reduced treatment effect and inaccurate examination result can be avoided. In another embodiment, the area of the hole wall of the mounting hole 5101 in contact with the medium pad 60 is wide, so that when the medium pad 60 slides with the sound-transmitting part 511 on the skin of the patient, the medium pad 60 is not cut by the narrow hole wall of the mounting hole 5101, so that the medium pad 60 does not lose its original use effect due to damage, and further, the ultrasonic treatment effect is not poor and the ultrasonic examination is not inaccurate.

[0071] Fig. 9 shows a cross-sectional view of the partial structure of the mounting member 50 and the body 10 in another embodiment of the present disclosure. In the example of Fig. 9, the mounting member 50 is inserted into the body 10 through at least one guide assembly 80. The guide assembly 80 includes a guide groove 801 and a guide post 81. The guide groove 801 is formed on one of the body 10 and the mounting member 50, and the guide post 81 is formed on the other one of the body 10 and the mounting member 50. In this embodiment, the guide groove 801 is formed on the inner wall of the mounting member 50 and extends along the direction of the recess, and the guide post 81 is formed on the body 10 and is slidingly combined with the guide groove 801. For example, when the guide post 81 slides to the end of the guide groove 801, the sound-transmitting portion 511 is in contact with the medium pad 60. In this way, the sound-transmitting portion 511 can be prevented from being excessively pressed against the medium pad 60 due to the excessive connection between the mounting member 50 and the body 10, and the sound-transmitting portion 511 or the medium pad 60 can be prevented from being broken.

[0072] In another embodiment, the guide groove 801 is formed on the body 10, and the guide post 81 is formed on the mounting member 50. In another embodiment, two guide assemblies 80 are symmetrically formed on the mounting member 50 and the body 10. In another embodiment, the mounting member 50 and the body 10 can be provided with a limiting assembly (for example, a clamping structure, not shown in the figure) to improve the fixing effect between the mounting member 50 and the body 10.

[0073] Fig. 10 shows an operation flowchart of the embodiment of the present disclosure. In the example of Fig. 10, the controller 21 is communicatively connected to the ultrasonic treatment master device. The operation flowchart includes the following steps:

[0074] S1: The ultrasonic treatment master device sends treatment parameters to the controller through the task receiving unit;

[0075] S2: The controller responds to a loading signal generated when the loading switch is triggered to enable the emission switch to be in an active state;

[0076] S3: The driving unit sends a start signal for implementing ultrasonic treatment to the driving unit in response to an emission signal generated when the emission switch is triggered;

[0077] S4: The driving unit sends an ultrasonic output implementation signal to the ultrasonic output unit in response to the start signal;

[0078] S5: The ultrasonic output unit starts to output ultrasonic waves in response to the ultrasonic output implementation signal;

[0079] S6: The driving unit determines the end of the ultrasonic wave emission based on the operating state of the ultrasonic output unit and forms an ultrasonic wave emission end signal;

[0080] S7: The driving unit sends the ultrasonic wave emission end signal to the controller;

[0081] S8: The controller determines whether the ultrasonic treatment in the treatment parameter is completed based on the treatment parameter, and if not, repeats S2-S7 until the ultrasonic treatment in the treatment parameter is completed.

[0082] Exemplarily, the treatment parameter includes ultrasonic emission time, interval time, ultrasonic emission times, etc. In some embodiments, the ultrasonic wave emission end signal can also be generated by the driving unit 24 and sent to the controller 21.

[0083] Exemplarily, to ensure safety and reliability during ultrasonic treatment, a continuous heartbeat protocol is established between the controller 21 and the driving unit 24:

[0084] When the controller 21 detects that the treatment parameter deviates from the preset safety threshold or the temperature sensor 28 overheats, an emergency program will be immediately started, the emergency braking information is communicated to the driving unit 24 through the internal communication path, and the power management unit 25 is instructed to cut off the power supply to the driving unit 24, and the emergency braking of the treatment process is implemented;

[0085] When the handheld ultrasonic treatment head enters the emergency braking state, the controller 21 does not terminate its self-checking and signal output functions, but enables a series of enhanced fault warning mechanisms, such as high-frequency flashing of the indicator light 26, vibration of the prompter 281 or screen display of emergency information, to effectively convey the abnormal working state of the handheld ultrasonic treatment head to the outside;

[0086] The driving unit 24 is designed with autonomous monitoring and fault response logic, and once it detects the interruption of communication with the controller 21 or detects abnormal system stability, it will immediately take preventive measures to stop all ultrasonic output operations and actively trigger an emergency broadcast signal to announce the current emergency situation in multiple channels (such as high-frequency flashing of the indicator light 26, vibration of the prompter 281 or screen display of emergency information) to ensure patient safety and immediate intervention by the user.

[0087] In another embodiment, the heartbeat protocol can also have other conditions, which are not limited to this.

[0088] Fig. 11 shows a structural schematic diagram of a computer device in an embodiment of the present disclosure. In the example of Fig. 11,

[0089] The computer device 120 comprises a bus 1201, a processor 1202, and a memory 1203. The processor 1202 and the memory 1203 can communicate through the bus 1201. The memory 1203 can store program instructions. The controller 21 in the foregoing embodiment can be implemented by the computer device 120. The processor 1202 can implement the steps of the controller 21 in FIG. 10 in the foregoing embodiment by running the program instructions in the memory 1203.

[0090] The bus 1201 can be a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For the convenience of representation, although only one thick line is shown in the figure, it does not mean that there is only one bus or only one type of bus.

[0091] In some embodiments, the processor 1202 can be implemented by a Central Processing Unit (CPU), a Micro Control Unit (MCU), a System On Chip, or a Field Programmable Gate Array (FPGA), etc. The memory 1203 can comprise a volatile memory for temporary storage of data during program execution, such as a Random Access Memory (RAM).

[0092] The memory 1203 can also comprise a non-volatile memory for data storage, such as a Read-Only Memory (ROM), a flash memory, a Hard Disk Drive (HDD), or a Solid-State Disk (SSD).

[0093] In some embodiments, the computer device 120 can also include a communicator 1204. The communicator 1204 is configured to communicate with the outside. In a specific example, the communicator 1204 can include one or a set of wired and / or wireless communication circuit modules. For example, the communicator 1204 can include one or more of, for example, a wired network card, a USB module, a serial interface module, and the like. Wireless communication modules follow wireless communication protocols including, for example, one or more of Near Field Communication (NFC) technology, Infared (IR) technology, Global System for Mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code division multiple access (WCDMA), Time-Division Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE), BlueTooth (BT), Global Navigation Satellite System (GNSS), and the like.

[0094] In summary, the hand-held ultrasonic treatment head provided in the embodiments of the present disclosure includes a body, and a control assembly fixedly arranged on the body and including an ultrasonic output unit, a controller, a driving unit, a loading switch and a transmitting switch. The loading switch and the transmitting switch are electrically connected to the controller. The controller is coupled to the driving unit. The driving unit is coupled to the ultrasonic output unit. A loading operation key is arranged. When the loading operation key is operated to trigger the loading switch, the loading switch outputs a loading signal to the controller. A transmitting operation key is arranged. When the transmitting operation key is operated to trigger the transmitting switch, the transmitting switch outputs a transmitting signal to the controller. The controller controls the driving unit to drive the ultrasonic output unit to transmit ultrasonic waves in response to the loading signal and the transmitting signal. When a user holds the hand-held ultrasonic treatment head with one hand, the user can avoid misoperation caused by a short stroke of a micro switch, and thus avoid incorrect treatment caused by misoperation. In addition, the long stroke of the mechanical key switch can provide the user with a better feeling of single-handed operation, so as to facilitate user operation and use, improve treatment efficiency and reduce errors. The medium pad can replace the existing water bag design, so that the overall volume of the ultrasonic treatment head in the embodiments of the present disclosure is small, so as to facilitate user operation and holding. In addition, the user can squeeze the sound-transmitting part, so that the gas between the medium pad and the notch and the sound-transmitting part can be discharged to the accommodating cavity, and finally discharged to the outside through the exhaust part, so as to avoid the influence of the gas between the medium pad and the notch and the sound-transmitting part on the spread and reflection of ultrasonic waves, and finally cause the error of the examination result.

[0095] The above embodiments only exemplarily illustrate the principles and effects of the present disclosure, and are not used to limit the present disclosure. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical idea of the present disclosure should be covered by the protection scope of the present disclosure.
