Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic therapy, in particular to an ultrasonic therapy head and an ultrasonic therapy device provided with the ultrasonic therapy head. Background Art

[0002] Ultrasonic therapy devices use the mechanical, thermal and physical effects of ultrasound to generate endogenous heat in the deep tissues of the human body, thereby causing local blood vessels to dilate, blood flow to accelerate, metabolism to increase, muscle tension to decrease, pain to decrease, and connective tissue to increase elasticity, thereby promoting recovery from certain diseases. Ultrasonic therapy devices treat the human body mainly by stimulating the ultrasonic transducer in the ultrasonic treatment head with a high-voltage pulse signal, causing the ultrasonic transducer to emit ultrasonic waves to achieve the purpose of treatment.

[0003] At present, the ultrasonic transducers in most ultrasonic treatment heads are fixedly arranged. Since the ultrasonic waves emitted by the ultrasonic transducer are focused into a point shape and the ultrasonic radiation area is small, medical staff are often required to manually move the ultrasonic treatment head during the treatment process to make the ultrasonic energy cover the entire treatment area as evenly as possible. However, due to human factors, it is difficult to ensure that the ultrasonic energy evenly covers the entire treatment area during the actual treatment process, resulting in limited treatment effects, which increases the workload of medical staff.

[0004] In order to solve the above problems, some existing ultrasonic treatment heads are equipped with a linear drive mechanism to drive the ultrasonic transducer to move, so that the ultrasonic transducer moves in one dimension and the ultrasonic wave is output in a straight line. Although the improved ultrasonic treatment head has a larger ultrasonic energy coverage range when it is stationary than the traditional ultrasonic treatment head, it can reduce the amplitude and range of movement of the ultrasonic treatment head when treating the same treatment area, and improve the uniformity of ultrasonic energy covering the entire area to be treated; however, since the ultrasonic transducer can only achieve one-dimensional movement, when the ultrasonic treatment head is stationary, the range of ultrasonic energy coverage is still relatively limited. Therefore, when treating the same treatment area, medical staff still need to control the ultrasonic treatment head to move vertically along the moving direction of the ultrasonic transducer so that the ultrasonic energy can completely cover the treatment area. In addition, when the ultrasonic treatment head is manually controlled to move, its moving speed, single moving distance, single moving stagnation time of the ultrasonic treatment head are all difficult to accurately control, resulting in poor treatment effect. Based on this, some existing ultrasonic treatment heads will add an additional linear drive mechanism, so that the two linear drive mechanisms are coupled to form a two-dimensional drive mechanism; however, the coupled two-dimensional drive mechanism has the following disadvantages:

[0005] First, when one linear drive mechanism 1 drives the ultrasonic transducer to move, it must simultaneously drive the other linear drive mechanism 2 to move synchronously, resulting in a large load on the linear drive mechanism 1 and a correspondingly large volume; and the two-dimensional drive mechanism formed by the coupling needs to occupy a larger space for the movement of the linear drive mechanism 2, which also results in a large volume of the ultrasonic treatment head.

[0006] Second, since the linear drive mechanism 2 must be connected between the linear drive mechanism 1 and the ultrasonic transducer, the linear drive mechanism 2 must be encapsulated and immersed in a sound-transmitting medium (such as water), thereby accelerating the damage speed of the linear drive mechanism 2. Summary of the invention

[0007] In order to solve the above problems, the main purpose of the present invention is to provide an ultrasonic treatment head that reduces energy consumption, facilitates miniaturization and has a long service life while ensuring that the ultrasonic transducer can achieve two-dimensional movement.

[0008] Another object of the present invention is to provide an ultrasonic therapeutic apparatus provided with the above-mentioned ultrasonic therapeutic head.

[0009] In order to achieve the first purpose of the present invention, the present invention provides an ultrasonic therapy head, including an ultrasonic transducer, a mounting frame and a first driving mechanism, the mounting frame is installed on the ultrasonic transducer, the first driving mechanism can drive the mounting frame to move in a first direction, wherein the first driving mechanism includes a first transmission module and a first driving module, the first driving module drives the mounting frame to move in the first direction through the first transmission module; the ultrasonic therapy head also includes a second driving mechanism, including a second transmission module and a second driving module, the second driving module drives the mounting frame to move in a second direction through the second transmission module, and the second direction is perpendicular to the first direction.

[0010] As can be seen from the above, the first driving module of the first driving mechanism drives the mounting frame to move in the first direction alone through the first transmission module, and the second driving module of the second driving mechanism drives the mounting frame to move in the second direction alone through the second transmission module, so that when the first driving mechanism drives the mounting frame to move, there is no need to drive the second driving mechanism to move. Similarly, when the second driving mechanism drives the mounting frame to move, there is no need to drive the first driving mechanism to move, thereby effectively reducing the energy consumption of the first driving module and the second driving module, reducing the volume of the first driving module, the second driving module and the ultrasonic treatment head, and making the space required to be occupied by the first driving mechanism and the second driving mechanism smaller, so as to facilitate the miniaturization of the ultrasonic treatment head; furthermore, this design can avoid the first driving module or the second driving module from being encapsulated in a sound transmission medium (such as water), thereby ensuring the service life and working reliability of the first driving module and the second driving module. The first driving mechanism and the second driving mechanism cooperate so that during the treatment, the ultrasonic treatment head remains stationary, and the ultrasonic transducer can perform two-dimensional movement with the cooperation of the first driving mechanism and the second driving mechanism, so as to achieve uniform output of ultrasonic energy over the entire area of ​​human tissue of a certain area, and this process does not require medical staff to manually control the movement of the ultrasonic treatment head so that the ultrasonic energy can completely cover the treatment area; in addition, under the action of the first driving mechanism and the second driving mechanism, the ultrasonic transducer can be accurately moved in the ultrasonic treatment head according to a preset moving speed, a preset single moving distance, etc., so as to ensure the treatment effect of the ultrasonic treatment head.

[0011] A further solution is that the ultrasonic treatment head includes a bracket; the first transmission module includes a first guide rod group and a first sliding assembly, the first guide rod group is parallel to the first direction and connected to the bracket, the first sliding assembly is slidably connected to the first guide rod group, the mounting frame is connected to the first sliding assembly, and the first driving module can drive the first sliding assembly to slide; the second transmission module includes a second guide rod group, a third guide rod group, a second sliding assembly, a third sliding assembly and a straight connecting rod, the second guide rod group is parallel to the first guide rod group and connected to the bracket, the third guide rod group is parallel to the second direction and connected to the bracket, the second sliding assembly is slidably connected to the second guide rod group, the second sliding assembly has a first hinge shaft parallel to the third direction, the third sliding assembly is slidably connected to the third guide rod group, the third sliding assembly has a second hinge shaft parallel to the third direction, the mounting frame is connected to the third sliding assembly, the first end of the straight connecting rod is hinged to the first hinge shaft, the second end of the straight connecting rod is hinged to the second hinge shaft, the second driving module can drive the second sliding assembly to slide, and the third direction is perpendicular to the first direction and the second direction respectively.

[0012] It can be seen from the above that, through the design of the first driving mechanism and the second driving mechanism, the first driving mechanism and the second driving mechanism can both directly drive the mounting frame and the ultrasonic transducer independently without the need to additionally drive another driving mechanism to move together, thereby effectively reducing the load of the driving mechanism and also saving the space required for the two-dimensional movement of the mounting frame and the ultrasonic transducer, thereby optimizing the structure of the ultrasonic treatment head and making the ultrasonic treatment head more miniaturized.

[0013] A further solution is that the first guide rod group includes two first guide rods distributed along the second direction, the first sliding assembly includes a first slider, an auxiliary slider and a first connecting rod, the first slider is slidably mounted on one of the first guide rods, the auxiliary slider is slidably mounted on the other first guide rod, the first connecting rod is connected between the first slider and the auxiliary slider, the mounting frame is connected to the first connecting rod, and the first driving module is connected to the first slider; the second guide rod group includes a second guide rod, the second sliding assembly includes a second slider, the second slider is slidably mounted on the second guide rod, the second driving module is connected to the second slider, the second slider is provided with a first hinge shaft, and in the second direction, the mounting frame is located between the first slider and the second slider; the third guide rod group includes two third guide rods distributed along the first direction, the third sliding assembly includes two third sliders and a second connecting rod, a third slider is slidably mounted on a third guide rod, the third slider is provided with a second hinge shaft, the second connecting rod is connected between the two third sliders, and the mounting frame is connected to the second connecting rod.

[0014] As can be seen from the above, the above design enables the first transmission module and the second transmission module to have good structural stability, so that the first transmission module and the second transmission module can stably and reliably support the mounting frame, and ensure the stability of the movement of the mounting frame and the ultrasonic transducer, prevent the mounting frame from tilting, and ensure that the focal position is always within the two-dimensional plane.

[0015] A further solution is that, in the third direction, the first slider is provided with a first gantry facing away from the ultrasonic transducer, and the second slider is provided with a second gantry facing away from the ultrasonic transducer; the first gantry has a first connecting portion connected to the driving end of the first driving module, and the second gantry has a second connecting portion connected to the driving end of the second driving module; in the third direction, the straight connecting rod is located between the second connecting portion and the second slider, and the second slider and the third slider are both located between the straight connecting rod and the auxiliary slider.

[0016] As can be seen from the above, the first gantry provides a better assembly space for the first drive module, avoids interference between the first drive module and the bracket, and ensures that the first drive module can reliably drive the first transmission module to move the mounting frame; similarly, the second gantry provides a better assembly space for the second drive module, avoids interference between the second drive module and the bracket, and ensures that the second drive module can reliably drive the second transmission module to move the mounting frame. In addition, by designing the relative positions of the first gantry, the second gantry, the straight connecting rod, the first slider, the second slider, the third slider, etc., the matching structure of the first drive mechanism and the second drive mechanism can be optimized, making the structure more compact and occupying less space; at the same time, it is also beneficial to reduce the focal length of the ultrasonic transducer, thereby reducing the volume of the ultrasonic transducer and the ultrasonic treatment head.

[0017] A further solution is that the ultrasonic therapy head includes a shell having a sound-transmitting port; an ultrasonic transducer, a mounting frame, a first transmission module, a second transmission module and a bracket are all arranged in the shell, a focusing plane of the ultrasonic transducer is arranged toward the sound-transmitting port, a focus of the focusing plane is located outside the shell, and a first drive module and a second drive module are both installed outside the shell; a first telescopic tube is sealedly connected between the first connecting portion and the shell, a driving end of the first drive module is passed through the first telescopic tube, a second telescopic tube is sealedly connected between the second connecting portion and the shell, and a driving end of the second drive module is passed through the second telescopic tube.

[0018] As can be seen from the above, since a sound-transmitting medium (such as water) is arranged in the shell to assist the ultrasonic wave to pass through the sound-transmitting port, arranging the first drive module and the second drive module outside the shell can prevent the first drive module and the second drive module from being infiltrated by the sound-transmitting medium, thereby protecting the first drive module and the second drive module, and facilitating the connection between the ultrasonic therapy head and the handle of the ultrasonic therapy instrument, thereby reducing the volume of the shell and the handle; and arranging the first telescopic tube and the second telescopic tube can ensure that the first drive module can reliably drive the first gantry to move and the second drive module can reliably drive the second gantry to move, while preventing the sound-transmitting medium from leaking from the connection between the shell and the first drive module and / or the second drive module, thereby ensuring the therapeutic effect of the ultrasonic therapy head.

[0019] A further solution is that the first drive module is a first electric push rod, the first drive rod of the first electric push rod is connected to the first connecting part, or the first drive module includes a first motor and a first screw, the first screw is connected to the drive shaft of the first motor and is threadedly connected to the first connecting part; the second drive module is a second electric push rod, the second drive rod of the second electric push rod is connected to the second connecting part, or the second drive module includes a second motor and a second screw, the second screw is connected to the drive shaft of the second motor and is threadedly connected to the second connecting part.

[0020] As can be seen from the above, the driving modes of the driving module are diverse to meet different usage requirements, cost requirements, parameter requirements, etc., making the production of the ultrasonic therapy head more flexible and improving the practicality of the ultrasonic therapy head.

[0021] A further solution is that when the first driving module is a first electric push rod, a first through hole is provided at the protruding end of the first driving rod, a second through hole is provided at the fixed end of the first driving rod, and the ultrasonic treatment head also includes a first slot-type photoelectric switch, and the detection light beam of the first slot-type photoelectric switch can pass through the first through hole or the second through hole; when the second driving module is a second electric push rod, a third through hole is provided at the protruding end of the second driving rod, a fourth through hole is provided at the fixed end of the second driving rod, and the ultrasonic treatment head also includes a second slot-type photoelectric switch, and the detection light beam of the second slot-type photoelectric switch can pass through the third through hole or the fourth through hole.

[0022] It can be seen from the above that when the driving module adopts an electric push rod, the cooperation between the slot-type photoelectric switch and the through hole on the electric push rod can realize the detection of the two extreme positions of extension and contraction of the driving rod, thereby avoiding collision between the mounting frame and the bracket and / or the transmission module.

[0023] A further solution is that, in the first direction, the first driving module and the second driving module are located on the same side of the mounting frame; in the second direction, the first driving module and the second driving module are distributed side by side.

[0024] As can be seen from the above, distributing the first drive module and the second drive module in parallel on the same side of the mounting frame can reduce the space occupied by the ultrasonic therapy head, optimize the structural layout of the ultrasonic therapy head, and facilitate the miniaturized design of the ultrasonic therapy head.

[0025] A further solution is that the bracket is made of stainless steel or plastic; the first transmission module is made of stainless steel or plastic; and the second transmission module is made of stainless steel or plastic.

[0026] As can be seen from the above, the above materials can enable the bracket, the first transmission module and the second transmission module to be placed in the sound transmission medium for a long time without being corroded, ensuring the reliability and stability of the two-dimensional movement of the ultrasonic transducer and ensuring the service life of the ultrasonic treatment head.

[0027] In order to achieve another object of the present invention, the present invention provides an ultrasonic therapeutic apparatus, including a handle, which also includes the above-mentioned ultrasonic therapeutic head, and the ultrasonic therapeutic head is installed on the handle.

[0028] As can be seen from the above, by using the above-mentioned ultrasonic therapy head, medical staff can make ultrasonic energy completely and evenly cover a certain treatment area without manually controlling the movement of the ultrasonic therapy head. The ultrasonic transducer can be moved accurately in the ultrasonic therapy head according to the preset movement speed, preset single movement distance, etc. to ensure the treatment effect.

[0037] Ultrasonic therapy device embodiment

[0038] Reference Figure 1 and Figure 2 The ultrasonic therapeutic device 100 includes an ultrasonic therapeutic head 101, a handle 102, a control unit 103, a control module 104, a display screen 105, a power module 106 and a charging interface 107.

[0039] Combination Figure 3 The ultrasonic treatment head 101 includes a shell 1, a mounting frame 2, a first driving mechanism 3, a second driving mechanism 4 and an ultrasonic transducer 7. The shell 1 has a housing cavity, and a sound-transmitting opening 12 is provided on the shell 1, and the sound-transmitting opening 12 penetrates the wall of the shell 1 to communicate with the housing cavity; the mounting frame 2 is arranged in the housing cavity, the ultrasonic transducer 7 is mounted on the mounting frame 2, and the focusing surface of the ultrasonic transducer 7 is arranged toward the sound-transmitting opening 12, so that the ultrasonic wave generated by the ultrasonic transducer 7 can pass through the sound-transmitting opening 12 and pass out of the ultrasonic treatment head 101, wherein the focus formed by the focusing surface of the ultrasonic transducer 7 is located outside the shell 1.

[0040] The housing cavity of the housing 1 is filled with a sound-transmitting medium (such as water), which is sealed and stored in the housing cavity to facilitate ultrasonic wave propagation; wherein the sound-transmitting opening 12 is sealed by a film 121 to prevent leakage of the sound-transmitting medium. The film 121 is made of a material with a low sound absorption coefficient to prevent the ultrasonic wave from being absorbed and weakened when it is transmitted out of the treatment head through the film 121; the film 121 can be made of materials such as polyethylene and polypropylene.

[0041] Combination Figure 4 and Figure 5 The first driving mechanism 3 is used to drive the mounting frame 2 to move in the first direction X, so that the mounting frame 2 drives the ultrasonic transducer 7 to move in the first direction X according to a preset mode; the second driving mechanism 4 is used to drive the mounting frame 2 to move in the second direction Y, so that the mounting frame 2 drives the ultrasonic transducer 7 to move in the second direction Y according to a preset mode. The first direction X is perpendicular to the second direction Y.

[0042] The second driving mechanism 4 cooperates with the first driving mechanism 3 so that during the treatment process, the ultrasonic treatment head 101 remains stationary, and the ultrasonic transducer 7 can achieve two-dimensional movement with the cooperation of the first driving mechanism 3, the second driving mechanism 4 and the mounting frame 2, thereby achieving uniform output of ultrasonic energy over the entire area of ​​human tissue of a certain area (treatment area). In this process, medical staff do not need to manually control the movement of the ultrasonic treatment head 101, and the ultrasonic energy can completely cover the treatment area by relying on the cooperative driving of the first driving module 32 and the second driving module 42.

[0043] It should be noted that the above-mentioned movement according to the preset mode includes but is not limited to at least one of the following requirements: movement according to a preset speed, movement according to a preset distance (continuous movement can be performed within the preset distance; it can also be a multiple intermittent movement of a certain distance until the preset distance is completed), movement according to a preset time (continuous movement can be performed within the preset time; it can also be a multiple intermittent movement until the preset time is completed, such as moving for a certain time, stopping for a certain time, moving for a certain time again, stopping for a certain time again, and repeating the cycle until the set requirements are met), and movement according to a preset ultrasonic intensity. It can be seen that under the action of the first driving mechanism 3 and the second driving mechanism 4, the ultrasonic transducer 7 can move accurately in the ultrasonic treatment head 101 according to the preset movement speed, the preset single movement distance, etc., to ensure the treatment effect.

[0044] A bracket 11 is provided in the shell 1, and the first driving mechanism 3 includes a first transmission module 31 and a first driving module 32, and the first driving module 32 drives the mounting frame 2 to move in the first direction X through the first transmission module 31; the second driving mechanism 4 includes a second transmission module 41 and a second driving module 42, and the second driving module 42 drives the mounting frame 2 to move in the second direction Y through the second transmission module 41.

[0045] Combination Figure 6 The first transmission module 31 includes a first guide rod group 311 and a first sliding assembly 312; the first guide rod group 311 is connected to the bracket 11, and the first guide rod group 311 is parallel to the first direction X; the first sliding assembly 312 is slidably connected to the first guide rod group 311, and the first sliding assembly 312 is connected to the mounting frame 2, so that the first sliding assembly 312 can drive the mounting frame 2 to move in the first direction X. The driving end of the first driving module 32 is connected to the first sliding assembly 312 to drive the first sliding assembly 312 to move in the first direction X. This design enables the first drive mechanism 3 to independently drive the mounting frame 2 and the ultrasonic transducer 7 to move in the first direction X without additionally driving the second drive mechanism 4 to follow the mounting frame 2 to move in the first direction X, thereby effectively reducing the load of the first drive mechanism 3 and thereby reducing the volume of the first drive module 32; in addition, since the first drive mechanism 3 does not need to drive the second drive mechanism 4 to move, there is no need to plan a space in the shell 1 to avoid the movement of the second drive mechanism 4, thereby optimizing the layout of the ultrasonic therapy head 101 and making the overall structure of the ultrasonic therapy head 101 more compact, thereby facilitating the miniaturization design of the ultrasonic therapy head 101.

[0046] Combination Figure 7The second transmission module 41 includes a second guide rod group 411, a third guide rod group 412, a second sliding assembly 413, a third sliding assembly 414 and a straight connecting rod 415; the second guide rod group 411 is connected to the bracket 11, and the second guide rod group 411 is parallel to the first guide rod group 311; the third guide rod group 412 is connected to the bracket 11, and the third guide rod group 412 is parallel to the second direction Y; the second sliding assembly 413 is slidably connected to the second guide rod group 411, and the second sliding assembly 414 is connected to the bracket 11. 13 has a first hinge shaft 41311, and the first hinge shaft 41311 is parallel to the third direction Z; the third sliding component 414 is slidably connected with the third guide rod group 412, the third sliding component 414 has a second hinge shaft 41411, the second hinge shaft 41411 is parallel to the third direction Z, and the third sliding component 414 is connected to the mounting frame 2; the first end of the straight connecting rod 415 is hinged to the first hinge shaft 41311, and the second end of the straight connecting rod 415 is hinged to the second hinge shaft 41411. The driving end of the second driving module 42 is connected to the second sliding component 413 to drive the second sliding component 413 to move in the first direction X. Since the second sliding component 413 and the third sliding component 414 are linked by the straight connecting rod 415, when the second sliding component 413 moves in the first direction X, the second sliding component 413 will push or pull the third sliding component 414 to move in the second direction Y through the straight connecting rod 415, thereby causing the third sliding component 414 to drive the mounting frame 2 to move in the second direction Y, thereby realizing the movement of the ultrasonic transducer 7 in the second direction Y. Among them, the third direction Z is perpendicular to the first direction X and the second direction Y respectively.

[0047] By designing the second transmission module 41, the force direction of the second drive module 42 on the second transmission module 41 is perpendicular to the direction in which the mounting frame 2 drives the ultrasonic transducer 7 to move, so that in the first direction X, the first drive module 32 and the second drive module 42 can be arranged on the same side of the mounting frame 2, and the first drive module 32 and the second drive module 42 are arranged side by side in the second direction Y. This design effectively reduces the space occupied by the ultrasonic therapy head 101, optimizes the structural layout of the ultrasonic therapy head 101, and thus reduces the volume of the ultrasonic therapy head 101.

[0048] In addition, the design of the second driving mechanism 4 enables it to independently drive the mounting frame 2 and the ultrasonic transducer 7 to move in the second direction Y, and there is no need to additionally drive the first driving mechanism 3 to follow the mounting frame 2 to move in the second direction Y, thereby effectively reducing the load of the second driving mechanism 4 and thereby reducing the volume of the second driving module 42; and, since the second driving mechanism 4 does not need to drive the first driving mechanism 3 to move, there is no need to plan a space in the shell 1 to avoid the movement of the first driving mechanism 3, thereby making the overall structure of the ultrasonic therapy head 101 more compact and reducing the volume of the ultrasonic therapy head 101.

[0049] Furthermore, in the present embodiment, the bracket 11 is in a frame-like shape, and the middle space enclosed by the frame-like bracket 11 is used to accommodate the mounting frame 2, so as to cooperate with the first driving mechanism 3 and the second driving mechanism 4 to stably drive the mounting frame 2 to move, thereby also facilitating the optimization of the first driving mechanism 3 and the second driving mechanism 4, so as to reduce the volume of the entire motion system, making the structure more compact, saving space, and facilitating the miniaturization design of the ultrasonic therapy head 101.

[0050] Matchingly, the first guide rod group 311 includes two first guide rods 3111, and the two first guide rods 3111 are distributed along the second direction Y at two opposite sides of the square-shaped bracket 11. It can be understood that the first guide rod 3111 is parallel to the first direction X and both ends are connected to the corners of the bracket 11. At this time, each first guide rod 3111 can be regarded as a side of the bracket 11. Correspondingly, the first sliding assembly 312 includes a first slider 3121, an auxiliary slider 3122 and a first connecting rod 3123, wherein the first slider 3121 is slidably installed on a first guide rod 3111, and the auxiliary slider 3122 is slidably installed on another first guide rod 3111, the first connecting rod 3123 is parallel to the second direction Y, and the first connecting rod 3123 is connected between the first slider 3121 and the auxiliary slider 3122, so that the first slider 3121 and the auxiliary slider 3122 can move synchronously in the first direction X, and the driving end of the first driving module 32 is connected to the first slider 3121; the first connecting rod 3123 is also connected to the mounting frame 2, so that the first connecting rod 3123 can drive the mounting frame 2 to move in the first direction X. Preferably, the first connecting rod 3123 passes through the mounting frame 2, so the first connecting rod 3123 and the mounting frame 2 can be connected without additional connecting components or connecting steps (because the second connecting rod 4142 cooperates with the first connecting rod 3123 to fix the mounting frame 2, see below), effectively simplifying the assembly steps of the two.

[0051] Matchingly, the second guide rod group 411 includes a second guide rod 4111. It can be understood that the second guide rod 4111 is parallel to the first direction X and both ends are connected to the corners of the bracket 11. At this time, the second guide rod 4111 can be regarded as an edge of the bracket 11. Correspondingly, the second sliding assembly 413 includes a second slider 4131, which is slidably mounted on the second guide rod 4111. The second driving module 42 is connected to the second slider 4131 to drive the second slider 4131 to move in the first direction X. Among them, the first hinge shaft 41311 is provided on the second slider 4131. In the second direction Y, the second guide rod 4111 and the auxiliary slider 3122 are located on the same side of the mounting frame 2, that is, the mounting frame 2 is located between the first slider 3121 and the second slider 4131.

[0052] Matchingly, the third guide rod group 412 includes two third guide rods 4121, and the two third guide rods 4121 are distributed along the first direction X at two opposite sides of the square-shaped bracket 11. It can be understood that the third guide rod 4121 is parallel to the second direction Y and both ends are connected to the corners of the bracket 11. At this time, each third guide rod 4121 can be regarded as a side of the bracket 11. Correspondingly, the third sliding assembly 414 includes two third sliders 4141 and a second connecting rod 4142, wherein a third slider 4141 is slidably mounted on each third guide rod 4121, the second connecting rod 4142 is parallel to the first direction X, and the second connecting rod 4142 is connected between the two third sliders 4141, so that the two third sliders 4141 can move synchronously in the second direction Y, and the second hinge shaft 41411 is arranged on the third slider 4141; it should be noted that the second hinge shaft 41411 can be set on both third sliders 4141, of course, the second hinge shaft 41411 can also be set on only one third slider 4141. In addition, the second connecting rod 4142 is also connected to the mounting frame 2 so that the second connecting rod 4142 can drive the mounting frame 2 to move in the second direction Y; preferably, the second connecting rod 4142 passes through the mounting frame 2, so the second connecting rod 4142 and the mounting frame 2 can be connected without the need for additional connecting components or connecting processes (because the first connecting rod 3123 and the second connecting rod 4142 cooperate to fix the mounting frame 2, see above), effectively simplifying the assembly steps of the two.

[0053] It can be seen that the frame-like bracket 11 cooperates with the first guide rod group 311, the second guide rod group 411 and the third guide rod group 412, which can not only improve the overall structural strength of the bracket 11, but also make the first guide rod group 311, the second guide rod group 411 and the third guide rod group 412 stably supported, thereby ensuring the stability of the movement of the mounting frame 2. Furthermore, it can also ensure that the two-dimensional movement of the ultrasonic transducer 7 is a plane rather than a curved surface, so as to better treat the human tissue at the same depth, and because the focus of the two-dimensional movement is on a plane rather than a curved surface, there is no need to increase the radius of the focal plane of the ultrasonic transducer 7 to keep the focus basically on the plane, so as to better reduce the volume of the ultrasonic treatment head 101.

[0054] In this embodiment, in the third direction Z, the first slider 3121 is provided with a first gantry 31211 facing away from the ultrasonic transducer 7 (which can also be understood as facing away from the sound-permeable port 12), and the second slider 4131 is provided with a second gantry 41312 facing away from the ultrasonic transducer 7. The first gantry 31211 can provide a better assembly space for the first drive module 32, so as to avoid interference between the first drive module 32 and the bracket 11 when the first drive module 32 is connected to the first slider 3121, and ensure that the first drive module 32 can reliably drive the first transmission module 31 to move the mounting frame 2; similarly, the second gantry 41312 can provide a better assembly space for the second drive module 42, so as to avoid interference between the second drive module 42 and the bracket 11 when the second drive module 42 is connected to the second slider 4131, and ensure that the second drive module 42 can reliably drive the second transmission module 41 to move the mounting frame 2. In addition, since the first gantry 31211 and the second gantry 41312 are both arranged to face away from the sound-transmitting port 12, the first drive module 32 and the second drive module 42 can be prevented from blocking the movement of the mounting frame 2. This is also beneficial for reducing the focal length of the ultrasonic transducer 7, thereby reducing the volume of the ultrasonic transducer 7 and the volume of the ultrasonic treatment head 101 (the larger the focal length, the larger the radius of the focusing surface, which will result in a larger volume of the ultrasonic transducer 7).

[0055] The first gantry 31211 has a first connection portion 31212 for connecting to the driving end of the first driving module 32 ; the second gantry 41312 has a second connection portion 41313 for connecting to the driving end of the second driving module 42 . The first connecting portion 31212 facilitates the setting of a sealing component (such as the first telescopic tube 51 described below) between it and the first driving module 32 to prevent leakage of the sound-transmitting medium in the shell 1, and also ensures that the driving end of the first driving module 32 is reliably connected to the first slider 3121, so as to reliably push the first sliding component 312 to drive the mounting frame 2 to move in the first direction X; similarly, the second connecting portion 41313 facilitates the setting of a sealing component (such as the second telescopic tube 52 described below) between it and the second driving module 42 to prevent leakage of the sound-transmitting medium in the shell 1, and also ensures that the driving end of the second driving module 42 is reliably connected to the second slider 4131, so as to reliably push the second sliding component 413 to cooperate with the straight connecting rod 415 and the third sliding component 414 to drive the mounting frame 2 to move in the second direction Y.

[0056] Further, in the third direction Z, the straight connecting rod 415 is located between the second connecting portion 41313 and the second slider 4131, and the second slider 4131 and the third slider 4141 are both located between the straight connecting rod 415 and the auxiliary slider 3122; it can be understood that, as a more reasonable distribution method, in the third direction Z, the second guide rod 4111 is located above the first guide rod 3111, and the height positions of the second guide rod 4111 and the third guide rod 4121 are basically consistent, so the height positions of the second slider 4131 and the third slider 4141 are also basically consistent, so the straight connecting rod 415 is basically perpendicular to the third direction Z, which is more conducive to the second slider 4131 driving the third slider 4141 to move in the second direction Y through the straight connecting rod 415, and the structure of the straight connecting rod 415 can also be simplified. In addition, by designing the relative positions between the above-mentioned transmission components, the matching structure of the first drive mechanism 3 and the second drive mechanism 4 is effectively optimized, making the structure more compact and occupying less space.

[0057] In addition, since the bracket 11, the mounting frame 2 and the ultrasonic transducer 7 are all located in the shell 1, it can be understood that the first transmission module 31 and the second transmission module 41 are also located in the shell 1; and in order to prevent the first drive module 32 and the second drive module 42 from being contaminated by the sound transmission medium, and in order to reduce the volume of the shell 1, it is preferred to arrange the first drive module 32 and the second drive module 42 outside the shell 1.

[0058] In this embodiment, the first driving module 32 adopts a first electric push rod, and the first driving rod of the first electric push rod is connected to the first connecting portion 31212. In order to reduce the length of the first driving rod extending to the first electric push rod housing 1 in the retracted state and enhance the structural strength of the first driving rod, it is preferred to set a first push-pull rod 31213 on the first connecting portion 31212, and the first push-pull rod 31213 extends toward the first driving module 32 in the first direction X, and the first push-pull rod 31213 is used for the first driving rod to be fixedly connected. The second driving module 42 adopts a second electric push rod, and the second driving rod of the second electric push rod is connected to the second connecting portion 41313. In order to reduce the length of the second driving rod extending to the second electric push rod housing 1 in the retracted state and enhance the structural strength of the second driving rod, it is preferred to set a second push-pull rod 41314 on the second connecting portion 41313, and the second push-pull rod 41314 extends toward the second driving module 42 in the first direction X, and the second push-pull rod 41314 is used for the second driving rod to be fixedly connected.

[0059] In order to ensure that the sound medium in the shell 1 will not leak at the connection between the first drive module 32 and the shell 1 and / or at the connection between the second drive module 42 and the shell 1; a first telescopic tube 51 is sealedly connected between the first connecting portion 31212 and the shell 1, and the driving end of the first drive module 32 and the first push-pull rod 31213 are arranged in the first telescopic tube 51; wherein, due to the existence of the first push-pull rod 31213 on the first connecting portion 31212, the first telescopic tube 51 can be arranged only between the side of the first connecting portion 31212 facing the first drive module 32 and the shell 1, and when arranged, the first connecting portion 31212 is sealedly connected to the first end of the first telescopic tube 51 (including but not limited to adhesive sealing, welding sealing, etc.), and the first end of the first telescopic tube 51 is closed, the second end of the first telescopic tube 51 is sealedly connected to the shell 1, and the first telescopic tube 51 is connected to the atmospheric pressure outside the shell 1 to ensure that the first telescopic tube 51 can be stably telescoped. Similarly,

[0060] A second telescopic tube 52 is sealedly connected between the second connecting portion 41313 and the shell 1, and the driving end of the second driving module 42 and the second push-pull rod 41314 are inserted into the second telescopic tube 52; wherein, due to the presence of the second push-pull rod 41314 on the second connecting portion 41313, the second telescopic tube 52 can be arranged only between the side of the second connecting portion 41313 facing the second driving module 42 and the shell 1. When arranged, the second connecting portion 41313 is sealedly connected to the first end of the second telescopic tube 52 (including but not limited to adhesive sealing, welding sealing, etc.), and the first end of the second telescopic tube 52 is closed, the second end of the second telescopic tube 52 is sealedly connected to the shell 1, and the second telescopic tube 52 is connected to the atmospheric pressure outside the shell 1 to ensure that the second telescopic tube 52 can be stably telescoped.

[0061] It can be seen that the provision of the first telescopic tube 51 and the second telescopic tube 52 can not only ensure that the first drive module 32 can reliably drive the first gantry 31211 to move and the second drive module 42 can reliably drive the second gantry 41312 to move, but can also prevent the sound transmission medium from leaking from the connection between the shell 1 and the first drive module 32 and / or the second drive module 42, thereby ensuring the treatment effect of the ultrasonic treatment head 101.

[0062] Further, a first through hole is provided at the extended end (i.e., the end close to the first push-pull rod 31213) of the first driving rod of the first electric push rod, and a second through hole is provided at the fixed end (i.e., the end away from the first push-pull rod 31213) of the first driving rod; a third through hole is provided at the extended end (i.e., the end close to the second push-pull rod 41314) of the second driving rod of the second electric push rod, and a fourth through hole is provided at the fixed end (i.e., the end away from the second push-pull rod 41314) of the second driving rod. In addition, the ultrasonic treatment head 101 further includes a first slot-type photoelectric switch 61 and a second slot-type photoelectric switch 62, both of which are electrically connected to the control unit 103, and both of which are arranged outside the housing 1; wherein the first driving rod passes through the slot of the first slot-type photoelectric switch 61, so that the detection light beam of the first slot-type photoelectric switch 61 can pass through the first through hole or the second through hole. The second driving rod passes through the notch of the second slot-type photoelectric switch 62, so that the detection light beam of the second slot-type photoelectric switch 62 can pass through the third through hole or the fourth through hole. The cooperation between the slot-type photoelectric switch and the through hole on the electric push rod can detect the two extreme positions of extension and contraction of the driving rod of the electric push rod, thereby preventing the mounting frame 2 from colliding with the bracket 11 and / or the transmission module, and also plays a limiting role, preventing the mounting frame 2 from crossing the safe position and preventing the mounting frame 2 from colliding with the bracket 11.

[0063] In some embodiments, the first drive module 32 no longer uses the first electric push rod, the second drive module 42 no longer uses the second electric push rod, the first connection part 31212 is no longer provided with the first push-pull rod 31213, and the second connection part 41313 is no longer provided with the second push-pull rod 41314. Instead, the first drive module 32 includes a first motor and a first lead screw, the first lead screw is connected to the driving shaft of the first motor, and the first lead screw is inserted into the accommodating chamber of the shell 1, and a first threaded hole is provided on the first connection part 31212, and the first threaded hole is threadedly connected to the first lead screw; the second drive module 42 includes a second motor and a second lead screw, the second lead screw is connected to the driving shaft of the second motor, and the second lead screw is inserted into the accommodating chamber of the shell 1, and a second threaded hole is provided on the second connection part 41313, and the second threaded hole is threadedly connected to the second lead screw. Based on this, first telescopic tubes 51 are provided on both sides of the first connection part 31212, and the side of the first connection part 31212 facing the first drive module 32 is sealed and connected to the first end of the first first telescopic tube 51, and the second end of the first first telescopic tube 51 is sealed and connected to the shell 1, and the first first telescopic tube 51 is connected to the atmospheric pressure outside the shell 1, and the side of the first connection part 31212 facing away from the first drive module 32 is sealed and connected to the first end of the second first telescopic tube 51, and the second end of the second first telescopic tube 51 is sealed and connected to the shell 1, and the first telescopic tube 51 is parallel to the first screw; in addition, if the second end of the second first telescopic tube 51 is connected to the atmospheric pressure outside the shell 1, the first end of the second first telescopic tube 51 can be closed, and if the second end of the second first telescopic tube 51 is not connected to the atmospheric pressure outside the shell 1 (that is, the second end is closed), a first connecting port is provided on the first connection part 31212, and the first connecting port only connects the two first telescopic tubes 51 but not to the accommodating cavity. Similarly, second telescopic tubes 52 are provided on both sides of the second connecting portion 41313, and the side of the second connecting portion 41313 facing the first driving module 32 is sealedly connected to the first end of the first second telescopic tube 52, the second end of the first second telescopic tube 52 is sealedly connected to the shell 1, and the first second telescopic tube 52 is connected to the external atmospheric pressure of the shell 1, and the side of the second connecting portion 41313 facing away from the second driving module 42 is sealedly connected to the first end of the second second telescopic tube 52, the second end of the second second telescopic tube 52 is sealedly connected to the shell 1, and the second telescopic tube 52 is parallel to the second lead screw; in addition, if the second end of the second second telescopic tube 52 is connected to the external atmospheric pressure of the shell 1, the first end of the second second telescopic tube 52 can be closed, and if the second end of the second second telescopic tube 52 is not connected to the external atmospheric pressure of the shell 1 (that is, the second end is closed), a second connecting port is provided on the second connecting portion 41313, and the second connecting port only connects the two second telescopic tubes 52 but not to the accommodating cavity.It can be seen that the driving mode of the driving module is diverse to meet different usage requirements, cost requirements, parameter requirements, etc., making the production of the ultrasonic therapy head 101 more flexible and improving the practicality of the ultrasonic therapy head 101.

[0064] The bracket 11 is preferably made of stainless steel or plastic; the first guide rod 3111, the first slider 3121, the auxiliary slider 3122, and the first connecting rod 3123 of the first transmission module 31 are made of stainless steel or plastic; the second guide rod 4111, the third guide rod 4121, the second slider 4131, the third slider 4141, the second connecting rod 4142, and the straight connecting rod 415 of the second transmission module 41 are made of stainless steel or plastic. This design enables the bracket 11, the first transmission module 31, and the second transmission module 41 to be placed in the sound transmission medium for a long time without being corroded, ensuring the reliability and stability of the two-dimensional movement of the ultrasonic transducer 7, and ensuring the service life of the ultrasonic treatment head 101.

[0065] The ultrasonic treatment head 101 is mounted on the handle 102, so that the medical staff can control the ultrasonic treatment head 101 to work and move through the handle 102. The control unit 103 is electrically connected to the ultrasonic transducer 7, the first drive module 32, the second drive module 42, the control module 104, the display screen 105, the power module 106 and the charging interface 107 to achieve coordinated control between the functional components.

[0066] The control unit 103 and the power module 106 are both installed in the handle 102. The power module 106 is used to power the ultrasonic transducer 7, the first drive module 32, the second drive module 42, the control module 104, the display screen 105, etc. The control module 104 is installed on the handle 102. The control module 104 is used to input control instructions to the control unit 103 so that the control unit 103 controls the ultrasonic treatment head 101 to work in a corresponding mode according to the relevant instructions. The display screen 105 is installed on the handle 102 and is preferably located on the back of the ultrasonic treatment head 101. The display screen 105 can be used to display the current working state of the ultrasonic treatment device 100 (including but not limited to the working parameters of the ultrasonic treatment head 101, the working mode of the ultrasonic treatment head 101, the battery remaining of the power module 106, the switch state of the ultrasonic treatment device 100, etc.), so as to facilitate medical staff to intuitively understand the current working state of the ultrasonic treatment device 100. The charging interface 107 is used to connect an external power supply cable to charge the power module 106; at the same time, the charging interface 107 can also serve as a data interface for connecting to an external data cable, thereby facilitating the control of the ultrasonic therapy head 101 or parameter setting, parameter update, system update, etc. of the control module.

[0067] The following briefly describes how the first driving mechanism 3 and the second driving mechanism 4 drive the mounting frame 2 to move:

[0068] When it is necessary to control the mounting frame 2 and the ultrasonic transducer 7 to move in the first direction X, the first driving module 32 is controlled to drive the first sliding assembly 312 to move along the first guide rod assembly 311, so that the first sliding assembly 312 drives the mounting frame 2 and the ultrasonic transducer 7 to move independently in the first direction X.

[0069] When it is necessary to control the mounting bracket 2 and the ultrasonic transducer 7 to move in the second direction Y, the second driving module 42 is controlled to drive the second sliding assembly 413 to slide along the second guide rod group 411, so that the second sliding assembly 413 pushes or pulls the third sliding assembly 414 to slide along the third guide rod group 412 through the direct connecting rod 415, and then the third sliding assembly 414 drives the mounting bracket 2 and the ultrasonic transducer 7 to move independently in the second direction Y.

[0070] When it is necessary to control the mounting frame 2 and the ultrasonic transducer 7 to move in two dimensions, the first driving module 32 is controlled to drive the first sliding assembly 312 to move along the first guide rod group 311 , and the second driving module 42 is controlled to drive the second sliding assembly 413 to slide along the second guide rod group 411 .

[0071] In summary, it can be seen that through the design of the ultrasonic therapeutic device 100 and its ultrasonic therapeutic head 101, medical staff can make ultrasonic energy completely and evenly cover a certain treatment area without manually controlling the movement of the ultrasonic therapeutic head 101, and the ultrasonic transducer 7 can be accurately moved in the ultrasonic therapeutic head 101 according to a preset moving speed, a preset single moving distance, etc., to ensure the treatment effect.
