[0002] Ultrasonic therapy devices usually use ultrasonic energy to treat the patient's lesion site. For example, a transcranial ultrasonic therapy device must first determine the patient's brain lesion through detection equipment, such as using magnetic resonance imaging for detection. The transcranial ultrasonic therapy device then emits transcranial ultrasound to provide directionally stimulated lesions in the patient's brain, thereby dilating the cerebral blood vessels at that location, improving cerebral microcirculation, and increasing the metabolic level of brain cells, thereby playing a role in treating and improving cognitive dysfunction, depression, Alzheimer's disease and other mental illnesses.

[0003] In the prior art, the ultrasonic therapy devices currently used usually have a fixed probe focal length. To achieve different focal stimulation depths, it is necessary to replace the probe with different ceramic chips, or to replace different collimators, that is, the same probe is matched with several collimators, which greatly increases the hardware cost and is inconvenient to operate.

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] An embodiment of the present invention specifically relates to an ultrasonic treatment device for performing ultrasonic treatment on a patient or user. The specific applicable parts are not limited, and all parts that can currently be treated with ultrasonic treatment can be compatible with it. For example, in some specific implementation scenarios, the ultrasonic treatment device can specifically be a transcranial ultrasonic treatment device, which is used to perform ultrasonic treatment stimulation on the head of the patient or user to produce a therapeutic effect.

[0033] However, a common problem at present is that the ultrasonic treatment devices currently used usually have a fixed probe focal length. In order to achieve different focal stimulation depths, it is necessary to replace the probe with different ceramic chips, or to replace different collimators, that is, the same probe is matched with several collimators, which greatly increases the hardware cost and is inconvenient to operate.

[0034] To this end, the purpose of an embodiment of the present invention is at least to provide an ultrasonic treatment device with adjustable focal length, which achieves infinite adjustment of the focal stimulation depth by adopting a simple and precise distance adjustment component, thereby achieving adjustable focal length without the need to configure multiple replaceable probes and collimators, facilitating operation and reducing costs.

[0035] In order to better illustrate an ultrasonic treatment device in an embodiment of the present invention, the following will be described in detail with reference to a specific embodiment and the accompanying drawings. The details are as follows:

[0036] Embodiment 1

[0037] like Figure 1-Figure 6 As shown, an ultrasonic treatment device provided in Embodiment 1 of the present invention includes a liquid storage component 10, an ultrasonic transmitting probe 20 arranged inside the liquid storage component 10, and a distance adjustment component 30 arranged on the liquid storage component 10 and connected to the ultrasonic transmitting probe 20. The distance adjustment component 30 is used to drive the ultrasonic transmitting probe 20 to slide in the liquid storage component 10 along the focal length direction to adjust the ultrasonic focal length.

[0038] Specifically, the liquid storage component 10 stores an ultrasonic coupling liquid, and the ultrasonic transmitting probe 20 is disposed in the liquid storage component 10 and is always immersed in the ultrasonic coupling liquid. The ultrasonic coupling liquid is used to couple the ultrasonic energy emitted by the ultrasonic transmitting probe 20, thereby realizing the transmission of ultrasonic energy. In specific implementation, the ultrasonic coupling liquid can be water or other coupling agents. Figure 2 As shown, the liquid storage assembly 10 specifically includes a shell 11 and a sound-transmitting membrane 12 disposed at the bottom of the shell 11 , and the shell 11 and the sound-transmitting membrane 12 form a liquid storage chamber 10a for storing ultrasonic coupling liquid.

[0039] The shell 11 is provided with a first liquid injection port 10b and a second liquid injection port 10c connected to the liquid storage cavity 10a. The first liquid injection port 10b and the second liquid injection port 10c are both located at the top of the shell 11, but the first liquid injection port 10b is higher than the second liquid injection port 10c. The first liquid injection port 10b and the second liquid injection port 10c are both equipped with a silicone plug 10d for plugging the liquid injection port. When it is necessary to inject ultrasonic coupling liquid, the first liquid injection port 10b and the second liquid injection port 10c are opened at the same time, and the ultrasonic coupling liquid is injected from the first liquid injection port 10b. When the ultrasonic coupling liquid flows out from the second liquid injection port 10c, the liquid injection is stopped, and the two liquid injection ports are sealed with the silicone plug 10d. At this time, the liquid in the cavity is the appropriate coupling liquid volume, that is, the liquid level of the ultrasonic coupling liquid is located at the second liquid injection port 10c.

[0040] It should be noted that the advantage of adopting the above-mentioned double liquid injection ports and liquid injection method is that the operator does not need to observe the liquid injection height in the cavity all the time, and the operation is convenient; and because there is a certain height difference between the first liquid injection port 10b and the second liquid injection port 10c, the liquid level in the cavity can only reach the second liquid injection port 10c during liquid injection, which well guarantees the injection capacity of the ultrasonic coupling liquid, and can also ensure that there is always a certain amount of residual space in the liquid storage chamber 10a. Since the ultrasonic transmitting probe 20 slides in the liquid storage chamber 10a, it will drive the ultrasonic coupling liquid to produce impact, and the residual space can just buffer the impact, thereby ensuring the subsequent movement of the ultrasonic transmitting probe 20.

[0041] In addition, in order to realize that the entire liquid storage assembly 10 is easy to disassemble and wash, the shell 11 specifically includes a lower shell 111, an upper shell 112 detachably connected to the top of the lower shell 111, and a pressure ring 113 detachably connected to the bottom of the lower shell 111. Among them, in some preferred cases of this embodiment, the pressure ring 113 is screwed to the bottom of the lower shell 111 to press and fix the sound-permeable membrane 12 to the bottom of the shell 11, and it is also convenient for the replacement of the sound-permeable membrane 12. In addition, the bottom outer wall of the upper shell 112 is provided with a card slot 1121 arranged along the circumferential direction, and the top inner wall of the lower shell 111 is provided with a card block 1111 arranged along the circumferential direction. When assembling, the bottom outer wall of the upper shell 112 is inserted and fitted with the top inner wall of the lower shell 111, and then the upper shell 112 is rotated circumferentially to make the card block 1111 snap into the card slot 1121. When disassembling, the upper shell 112 can be rotated in the opposite direction. Of course, in order to achieve reliable sealing, sealing structures such as sealing rings can be set at the mating parts of the lower shell 111, the upper shell 112 and the pressure ring 113 to achieve sealing, and in order to achieve the reliability of the detachable connection, a plurality of groups of screw-on card structures composed of the card slot 1121 and the card block 1111 can be set between the upper shell 112 and the lower shell 111.

[0042] A sliding structure is provided between the ultrasonic transmitting probe 20 and the inner wall of the liquid storage component 10, so that the ultrasonic transmitting probe 20 can slide in the liquid storage component 10 along the focal length direction. In this embodiment, the focal length direction is the height direction of the ultrasonic treatment device, that is, the focal length is adjusted by lifting and lowering the ultrasonic transmitting probe 20. The sliding structure includes a slide 41 and a slider 42 that slides with the slide 41. One of the slide 41 and the slider 42 is provided on the inner wall of the housing 11, and the other is provided on the side wall of the ultrasonic transmitting probe 20. In this embodiment, the slide 41 is provided on the inner wall of the housing 11, and the slider 42 is provided on the side wall of the ultrasonic transmitting probe 20, and the slide 41 is divided into two, which are arranged on the upper housing 112 and the lower housing 111 respectively. The upper housing 112 and the lower housing 111 are screwed together to form a complete slide 41.

[0043] Among them, the distance adjustment component 30 includes a connector 31 and a distance adjustment kit 32, the connector 31 is connected to the ultrasonic transmitting probe 20, the distance adjustment kit 32 is connected to the liquid storage component 10 and the connector 31, and can drive the ultrasonic transmitting probe 20 to slide along the focal length direction by rotating the distance adjustment kit 32. That is, in the embodiment, it is set to drive the connector 31 to rise and fall by rotating the distance adjustment kit 32, thereby driving the ultrasonic transmitting probe 20 to rise and fall and slide. More specifically, the distance adjustment kit 32 specifically includes a clamping ring 321 and a distance adjustment knob 322 fixedly connected to the clamping ring 321, the clamping ring 321 is rotatably connected to the liquid storage component 10, so the distance adjustment knob 322 is also rotatably connected relative to the liquid storage component 10, and the distance adjustment knob 322 is threadedly connected to the connector 31. When the distance adjustment knob 322 is rotated, it will be driven by the threaded connection to drive the connector 31 to rise and fall, thereby driving the ultrasonic transmitting probe 20 to rise and fall and slide.

[0044] In order to facilitate the adjustment of the focal length, in the preferred implementation of this embodiment, the connection member 31 is provided with a focal length scale value 31a (scale), and when the distance adjustment knob 322 is rotated to drive the connection member 31 to rise and fall, the focal length scale value 31a on the connection member 31 also changes accordingly, and since the probe follows the connection member 31 to rise and fall synchronously, the currently adjusted focal length is fed back. In addition, an annular sticker 3222 can be attached to the distance adjustment knob 322, and the focus adjustment direction is set on the annular sticker 3222, for example, the clockwise direction represents an increase in focal length, and the counterclockwise direction represents a decrease in focal length, etc., thereby greatly facilitating the adjustment of the probe focal length. Preferably, the threads on the distance adjustment knob 322 and the connection member 31 should satisfy that the thread lead angle is less than the equivalent friction angle, so as to achieve a self-locking effect, that is, after adjusting to the desired focal length, the probe will not fall due to the weight, thereby causing inaccurate focal length.

[0045] It should be noted that since the present embodiment adopts a threaded matching method to achieve focal length adjustment, the threaded transmission can achieve stepless adjustment, thereby realizing stepless adjustment of the probe focal length. In some specific implementation situations of the present embodiment, the probe focal length in the present embodiment can be steplessly adjusted within the range of 13 to 37 mm to meet the treatment needs of different superficial and medium depths of the skull. In addition, since this type of threaded matching method has a self-locking function, there is no need for additional self-locking structure, the structure is compact and the focal length is maintained more accurately.

[0046] In order to prevent the ultrasonic coupling liquid in the liquid storage chamber 10a from affecting the distance adjustment component 30 and the connection part between the distance adjustment component 30 and the ultrasonic transmitting probe 20, the embodiment of the present invention further includes a telescopic component 50 for isolating the distance adjustment component 30 and the liquid storage chamber 10a. Figure 5-Figure 6 As shown, the telescopic assembly 50 includes a telescopic cover 51, an upper pressing plate 52 and a lower pressing plate 53. The upper end of the telescopic cover 51 is pressed and fixed to the top of the housing 11 by the upper pressing plate 52, and the lower end of the telescopic cover 51 is pressed and fixed to the top of the ultrasonic transmitting probe 20 by the lower pressing plate 53. The telescopic cover 51 covers the outside of the connecting member 31, thereby isolating the distance adjustment assembly 30 and the liquid storage chamber 10a to prevent the ultrasonic coupling liquid from affecting these precision parts. At the same time, the telescopic cover 51 can be freely extended and retracted without affecting the lifting and lowering of the ultrasonic transmitting probe 20. In addition, in order to ensure the sealing of the connection part, the telescopic cover 51 and the upper pressing plate 52 and the lower pressing plate 53 can be sealed by sealing structures such as sealing rings.

[0047] In addition, in order to ensure that the ultrasonic transmitting probe 20 is always immersed in the ultrasonic coupling liquid, when the telescopic cover 51 is compressed to the minimum length, the second liquid injection port 10 c is still higher than the ultrasonic transmitting probe 20 .

[0048] In addition, in the specific implementation, Figure 3 and Figure 5 As shown, the clamping ring 321 is rotatably connected to the upper pressing plate 52. Specifically, a through hole 521 is provided at the top center of the upper pressing plate 52. The through hole 521 allows the connecting member 31 to pass through, so that the connecting member 31 can be connected to the ultrasonic transmitting probe 20 in the housing 11 and can be successfully and freely raised and lowered. An annular flange 522 extends outward from the top edge of the through hole 521. An inwardly concave annular groove 52a is formed between the annular flange 522 and the upper pressing plate 52. The inner wall of the clamping ring 321 is at least partially inserted into the annular groove 52a, thereby realizing the rotatable connection of the clamping ring 321. The annular flange 522 limits the axial disengagement of the clamping ring 321. Optionally, in order to facilitate disassembly, the clamping ring 321 is formed by splicing and clamping two semicircular clamping rings.

[0049] Furthermore, in order to limit the distance adjustment knob 322 from coming off the connecting member 31, the distance adjustment assembly 30 also includes a limit cap 33 connected to one end of the connecting member 31 away from the ultrasonic transmitting probe 20, and the limit cap 33 is used to control the maximum distance of the distance adjustment knob 322 moving upward relative to the connecting member 31. The limit cap 33 is screwed to the connecting member 31 to facilitate disassembly. In addition, a limit ring 3221 extends from the side of the distance adjustment knob 322 toward the limit cap 33. When the limit ring 3221 abuts against the limit cap 33, the connecting member 31 will not be able to move downward further. The limit ring 3221 is made of transparent organic glass, so that the focal length scale value on the current connecting member 31 can be read through the limit ring 3221 to understand the current probe focal length.

[0050] More specifically, the ultrasonic transmitting probe 20 is connected to a cable 21 for transmitting ultrasonic energy, the cable 21 is connected to the ultrasonic transmitting probe 20 via a cable connector 22, and the connector 31 is screwed to the cable connector 22, so that the entire cable connector can be easily replaced. At the same time, the connector 31 and the limiting cap 33 are both hollow structures, and the cable 21 passes through the hollow structure.

[0051] In some optional embodiments of the present embodiment, the ultrasonic treatment device also includes an optical positioning component 60, the principle of which is: the optical camera confirms the focal coordinates of the ultrasonic transmitting probe 20 by acquiring the spatial coordinates of four optical reflection balls 62, and then converts the coordinates into MRI image coordinates through software processing and displays them on the MRI graphic interface, so that the position of the focus in the skull can be intuitively observed; the optical positioning component 60 is connected to the distance adjustment component 30, and can move along the focal length direction with the ultrasonic transmitting probe 20. The optical positioning component 60 is specifically used to optically locate the probe focus. Specifically, the optical positioning component 60 is specifically an optical positioning system, which realizes automatic optical positioning of the probe focus through the optical positioning principle. In actual operation, the optical positioning system cooperates with related optical probes and equipment to realize the optical positioning of the entire treatment probe, so that the operator can better confirm the position of the focus in the skull. The optical positioning component 60 specifically includes an optical positioning bracket 61, and optical reflection balls 62 dispersedly fixed on the optical positioning bracket 61. Specifically, as Figure 2 As shown, four optical reflective balls 62 are specifically provided, and the four optical reflective balls 62 are arranged in a cross shape, three of which are in the same plane, and the other one has a height difference of 5mm with the other planes. That is, in this embodiment, the ultrasonic treatment device is also equipped with an optical positioning system, which can optically locate the focus of the probe, solving the problem that the traditional ultrasonic treatment device requires additional magnetic resonance equipment for positioning. This makes the treatment and operation process more flexible and changeable, greatly reduces the use cost, and improves the use efficiency and positioning accuracy.

[0052] In addition, the optical positioning assembly 60 is specifically connected to the limiting cap 33. Specifically, the limiting cap 33 is provided with a screw hole 331, and the bottom of the optical positioning bracket 61 is fixed to the limiting cap 33 by a bolt 63, and the bolt 63 is threadedly connected to the screw hole 331.

[0053] In summary, the ultrasonic treatment device in the embodiment of the present invention is provided with a sliding structure between the ultrasonic transmitting probe 20 and the inner wall of the liquid storage component 10, and a distance adjustment component 30 is configured to drive the ultrasonic transmitting probe 20 to slide in the liquid storage component 10 along the focal length direction to adjust the ultrasonic focal length of the probe. It is easy to use and does not require the configuration of multiple replaceable probes and collimators, thereby reducing costs. In addition, the distance adjustment component 30 has a compact structure, a clever design, and precise distance adjustment. In addition, it is configured with an optical positioning system, and does not require positioning through a magnetic resonance device, making it more flexible and changeable during treatment and operation, greatly reducing the cost of use, while improving the use efficiency and positioning accuracy.

[0054] Embodiment 2

[0055] See also Figure 7 , which shows an ultrasonic treatment device in the second embodiment of the present invention. The difference between the ultrasonic treatment device in this embodiment and the ultrasonic treatment device in the first embodiment is that:

[0056] First, as the ultrasonic transmitting probe 20 moves up and down in the ultrasonic coupling liquid, positive and negative pressures will be generated in the liquid storage chamber 10a due to volume changes. The generation of these air pressures will hinder the movement of the ultrasonic transmitting probe 20 to a certain extent, thereby affecting the accuracy of focal length adjustment. Therefore, how to balance the air pressure changes in the liquid storage chamber 10a caused by the lifting and lowering movement is a problem to be solved in order to further improve the accuracy of focal length adjustment.

[0057] To this end, in this embodiment, a breathable structure is provided on the top of the housing 11 and / or the upper pressure plate 52, the breathable structure is higher than the first liquid injection port 10b, and a waterproof breathable membrane 70 is provided in the breathable structure. The air pressure balance in the cavity is achieved through the breathable structure, and because the breathable structure is provided at the top (higher than the first liquid injection port 10b) and is provided with the waterproof breathable membrane 70, leakage of the liquid in the cavity can be prevented.

[0058] In some preferred cases of this embodiment, the ventilation structure is arranged as follows: a first ventilation hole 114 is provided on the top of the housing 11, a second ventilation hole 523 opposite to the first ventilation hole 114 is provided on the upper pressing plate 52, the second ventilation hole 523 is smaller than the first ventilation hole 114, a waterproof ventilation membrane 70 is arranged between the first ventilation hole 114 and the second ventilation hole 523, and the waterproof ventilation membrane 70 is pressed against the top of the housing 11 by the upper pressing plate 52. That is, this layout can achieve ventilation, and at the same time, can cleverly arrange the waterproof ventilation membrane 70 by means of the pressing effect of the upper pressing plate 52, so that there is no need to set up an additional fixed installation structure of the waterproof ventilation membrane 70.

[0059] Therefore, this embodiment further provides a special air permeable structure to automatically balance the changes in the air pressure in the cavity caused by the lifting and lowering of the probe, thereby avoiding the influence of the lifting and lowering of the probe due to the unbalanced air pressure in the cavity, and further improving the accuracy of the focal length adjustment.

[0060] It should be pointed out that the implementation principle and technical effects of the device provided in the second embodiment of the present invention are similar to those of the first embodiment. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in the first embodiment.
