In the embodiment of the present application, the second ultrasonic transducer unit 23 is disclosed as being mounted to the bracket 21 along the circumferential direction of the first ultrasonic transducer unit 22. The structure arrangement omits a shell 16 structure for bearing the ultrasonic transduction units in the shell, achieves the effect that more ultrasonic transduction units can be arranged in the same volume of installation space, has larger space utilization rate compared with the horizontal arrangement design, and ensures that the emission surface of the ultrasonic transduction unit combination structure can emit ultrasonic energy meeting the treatment purpose under the same preset electric energy output power (consistent with the electric energy output power required by the traditional horizontal arrangement ultrasonic transduction unit combination structure).

The focusing point of the emitting surface of the ultrasonic transduction unit is positioned outside the treatment window 11 and is precisely positioned on target treatment tissues such as dermis layers, subcutaneous fat layers, SMAS layers and the like so as to achieve the effects of lifting, tightening, tendering and reducing fat. As shown in fig. 2, focusing points of ultrasonic waves emitted by the emitting surfaces of the first ultrasonic transducer unit 22 and the second ultrasonic transducer unit 23 are arranged at intervals in a direction perpendicular to the therapeutic window, so that the ultrasonic transducer unit 2 has two depths (the emitting surfaces of different ultrasonic transducer units have multiple identical or different depth ranges by adjusting the output power of electric energy, the structure and the control method are not described in detail in the prior art), when the ultrasonic transducer unit 2 works, the multiple depth ranges work simultaneously, and therefore, when the novel ultrasonic therapeutic head treats subcutaneous tissues of a human body, multiple layers of subcutaneous tissues in the human body can be treated simultaneously, and the therapeutic efficiency is improved.

Referring to fig. 1 to 4, fig. 4 is a schematic plan view of a first ultrasonic transducer 22 and a second ultrasonic transducer 23 in an ultrasonic therapeutic head according to the present application, in which the first emitting surface 221 is concave and curved in a direction away from the therapeutic window 11; and/or, the second ultrasonic transduction unit 23 is annular, and the second emitting surface 231 is concave and curved towards the direction away from the treatment window 11.

Of course, in other embodiments, there are a plurality of second ultrasonic transducer units 23, and a plurality of second ultrasonic transducer units 23 are mounted on the support 21 at regular intervals along the circumferential direction of the first ultrasonic transducer unit 22.

The plurality of second ultrasonic transducer units 23 are uniformly arranged on the bracket 21 at intervals along the peripheral direction of the first ultrasonic transducer unit 22, and the structure is arranged, so that the space utilization rate is higher, and the emission surface of the ultrasonic transducer unit combined structure can emit ultrasonic energy meeting the treatment purpose under the same preset electric energy output power (consistent with the electric energy output power required by the existing horizontally arranged ultrasonic transducer unit combined structure).

In practical applications, the driving mechanism 3 may be a linear screw motor connected to the bracket 21 in a driving manner, and of course, the driving mechanism includes but is not limited to the above-mentioned driving mechanism. The power output end 31 of the driving motor stretches into the inner cavity 12 to reciprocate, impurities are easy to bring into the inner cavity 12, and in order to solve the problems, a sealing structure 131 is arranged at the input hole 13 and sleeved outside the output end 31, so that the input hole 13 is sealed. The treatment depth can be obtained through feedback of an encoder of the motor, and a depth detection module can be additionally arranged for detection.

In addition, the ultrasonic transducer unit 2 has less energy loss when transmitting ultrasonic energy in a relatively closed environment or an environment filled with an ultrasonic transmission medium, so that the addition of the sealing structure 131 to the input hole 13 can reduce the ultrasonic energy loss to some extent and increase the therapeutic effect when contacting the skin surface of the human body.

In the technical solution of the present application, the sealing structure 131 is an elastic film, and the elastic film encloses a cylindrical structure with two open ends, and two ends of the cylindrical structure are respectively connected to the housing 1 and the bracket 21.

The driving mechanism can drive the ultrasonic transduction unit to move in a direction perpendicular to the treatment window, and further away from or close to the treatment window.

An embodiment of the present application further provides a method for controlling an ultrasonic therapy head, referring to fig. 5, the method includes:

step S110, determining a target working depth according to input information;

in this embodiment, the input information is information about the operation of the ultrasound therapy head that the ultrasound therapy device sends to the ultrasound therapy head, wherein the ultrasound therapy device is equipped with an interactive control panel for receiving user input information. The user can input information on the control panel, and the control panel sends the input information to the ultrasonic treatment head; the historical treatment data obtained by the ultrasonic treatment apparatus may be used, and is not particularly limited herein.

As an alternative implementation manner, the control panel determines the working depth according to the received touch information so as to generate input information and send the input information to the ultrasonic treatment head; acquiring input information sent by a control panel, and determining the working depth of the ultrasonic treatment according to the input information; the working depth is determined as the target working depth.

Illustratively, the user inputs the working depth of the ultrasonic treatment to the control panel, and the control panel sends the working depth to the ultrasonic treatment head in a wired transmission and/or wireless transmission mode; after receiving the working depth, the ultrasonic treatment head takes the working depth as a target working depth.

As another alternative implementation manner, the control panel determines a treatment item according to the received touch information, determines a working depth corresponding to the treatment item, generates input information based on the working depth, and sends the input information to the ultrasonic treatment head.

For example, when the control panel detects the touch information, a treatment item is determined according to the touch information, a working depth associated with the treatment item is determined according to preset information, and the working depth is sent to the ultrasonic treatment head.

As another optional implementation manner, the control panel determines a treatment item according to the received touch information and personnel information of a person to be treated, and determines a working depth corresponding to the treatment item; and updating the working depth according to the historical treatment data associated with the personnel information, so that the updated working depth is more in line with the body structure of the personnel to be treated.

In this embodiment, the control panel may further be provided with a window of a treatment mode, and the treatment mode is determined according to touch information received by the window, where the treatment mode is a mode of releasing energy when the ultrasonic transduction unit is driven by the driving mechanism.

The control panel determines a treatment mode according to the touch information when detecting the touch information, wherein the treatment mode is that the ultrasonic transduction unit stops outputting energy when being driven by the driving mechanism to be in a state of being far away from or approaching to the treatment window.

The control panel determines a treatment mode according to the touch information when detecting the touch information, wherein the treatment mode is that the ultrasonic transduction unit synchronously outputs energy when being driven by the driving mechanism to be in a state of being far away from or approaching to a treatment window.

The ultrasonic treatment head may emit ultrasonic waves that penetrate the surface layer of the skin so that the ultrasonic waves are concentrated subcutaneously. The working depth refers to the distance from the skin surface at which the ultrasonic waves transmitted by the ultrasonic treatment head are focused. The target working depth refers to the currently set working depth. The target working depth may be a single value, may be a plurality of values, or may be a numerical range.

The target working depth is, for example, 3 mm. Alternatively, the target working depth is 3 mm, 4 mm and 5 mm. Alternatively, the target working depth is 2 mm to 4.5 mm.

Step S120, determining the motion parameters of the driving mechanism according to the target working depth;

in this embodiment, the driving mechanism may drive the ultrasonic transducer unit to move in the vertical direction of the ultrasonic treatment head by moving, thereby adjusting the current working depth.

As an alternative embodiment, the working depth of the ultrasound transducer unit at the same location is fixed, i.e. the working depth of the ultrasound therapy head is adjusted by moving up and down. The emitting surface of the ultrasonic transduction unit approximates to an arc, so that the focusing depth of the ultrasonic transduction unit approximates to the radius of a circle corresponding to the arc, the focusing depth of the ultrasonic transduction unit is a fixed value, the current working depth of the ultrasonic treatment head is the difference between the focusing depth and a first relative distance, and the first relative distance is the distance from the emitting surface of the ultrasonic transduction unit to the treatment window. When the ultrasonic transduction unit moves along the vertical direction of the ultrasonic treatment head, the first relative distance is changed, and the current working depth is changed accordingly.

For example, when the target working depth is a single value, the motion parameter is a motion parameter required by the driving mechanism to move from the current position to the position corresponding to the target working depth.

Illustratively, when the target working depth is a plurality of values, the motion parameters are the parameters required to move from the current position to the first working depth, and the parameters required to move from the first working depth to the second working depth, and so on.

For example, when the target working depth is a numerical range, the motion parameter is a parameter required by the driving mechanism to drive the ultrasonic transduction unit to reciprocate in the numerical range.

As another alternative, the working depth of the ultrasound transducer unit itself is variable, the working depth being adjusted by adjusting the curvature of the surface of the ultrasound transducer unit. The working depth of the ultrasonic transduction unit can be changed, and the ultrasonic transduction unit can be matched with the ultrasonic transduction unit to move, so that the working depth of the ultrasonic transduction unit can be adjusted.

Optionally, step S120 includes:

step S121, determining the working time associated with the target working depth;

step S122, determining the motion parameter according to the target working depth and the working time.

As an alternative implementation manner, when the target working depth is a single value, determining the working time associated with the target working depth, determining the distance value required to be moved by the ultrasonic transduction unit according to the target working depth and the corresponding working time, and the time for staying at the position; and determining the motion parameters of the driving mechanism according to the target working depth and the working time. And acquiring a motion parameter coding program of the driving mechanism, and generating motion parameters of the driving mechanism based on the program according to the target working depth and the working time.

By way of example, the target working depth is determined to be 3 millimeters, with a corresponding working time of 2 minutes; and acquiring a motion parameter coding program of the driving mechanism, determining the working scheme to be 36 turns of the motor according to the basic parameters of the driving mechanism of 12 turns/mm (namely, the motor is required to rotate for 12 turns when moving by one mm) and 2 minutes after the driving mechanism reaches the target position. And generating the executable motion parameters of the driving mechanism according to the coding program and the working scheme. Wherein the drive mechanism performs the motion parameter, rotates 36 revolutions and stays for 2 minutes after reaching the target position.

As another alternative implementation, when the target working depth is a single value, the distance value of the ultrasonic transduction unit to be moved is determined according to the target working depth, and then the motion parameter of the driving mechanism is determined. The working time is controlled by the rest of the components to time.

Optionally, step S120 further includes:

step S123, obtaining a difference value between the target working depths;

when the target working depth is a plurality of values, a difference between the respective target working depths is obtained.

Step S124, determining the movement distance of the driving mechanism according to the difference value;

and step S125, determining the motion parameters according to the movement distance.

As an alternative implementation manner, when the target working depth is a numerical value interval, acquiring a difference value between the first target depth and the second target depth, determining a distance to be moved by the driving mechanism according to the difference value, and recording the distance as a movement distance; according to the movement distance and basic parameters of the driving mechanism, a working scheme is determined, and according to the working scheme and a coding program associated with the driving mechanism, executable motion parameters of the driving mechanism are generated, so that the driving mechanism can move from a position corresponding to a first target working depth to a position corresponding to a second target working depth.

Illustratively, the first target working depth is determined to be 3 millimeters and the second target working depth is determined to be 5 millimeters; the difference between the two target working depths was determined to be 2 mm, i.e., the movement pitch of the driving mechanism was determined to be 2 mm. According to the movement interval of 2 mm and the basic parameter of the driving mechanism of 12 revolutions per mm, the working scheme is determined to be 24 revolutions of the motor of the driving mechanism, and according to the working scheme and the coding program associated with the driving mechanism, the executable movement parameter of the driving mechanism is generated, so that the driving mechanism can move from the position corresponding to 3 to the position corresponding to 5.

Illustratively, the first target working depth is determined to be 2 millimeters and the second target working depth is determined to be 5 millimeters; the difference between the two target working depths was determined to be 3 mm, i.e., the movement pitch of the driving mechanism was 3 mm. According to the movement spacing of 3 mm and the basic parameter of the driving mechanism of 12 revolutions per mm, determining that the working scheme is that the motor of the driving mechanism rotates 36 revolutions, recording that the rotating direction is the positive direction, and according to the working scheme and the coding program associated with the driving mechanism, generating a first movement parameter executable by the driving mechanism, so that the driving mechanism can move from the position corresponding to 2 mm to the position corresponding to 5 mm. Then determining that the first target working depth is 5 mm, and determining that the second target working depth is 2 mm; the difference between the two target working depths was determined to be 3 mm, i.e., the movement pitch of the driving mechanism was 3 mm. According to the movement spacing of 3 mm and the basic parameter of the driving mechanism of 12 revolutions per mm, determining that the working scheme is that the motor of the driving mechanism rotates 36 revolutions, and generating a second executable movement parameter of the driving mechanism according to the working scheme and the coding program associated with the driving mechanism, wherein the direction of the motor rotates in the reverse direction at the moment, so that the driving mechanism can move from a position corresponding to 5 mm to a position corresponding to 2 mm; and generating the motion parameters according to the first motion parameters and the second motion parameters.

As an alternative implementation manner, obtaining the difference value between each target working depth, forming a difference value sequence according to each difference value, and determining the movement distance between the working positions of the driving mechanism corresponding to each target working depth based on the difference value sequence; the movement parameters of the drive are determined on the basis of the respective movement distances.

The target working depth has three values, for example, 3 mm, 5 mm and 6 mm, respectively; the difference before each target working depth is determined to be 2 mm and 1 mm, and then the motion parameters at the working depth of 5 mm and 6 mm are determined according to the difference of 2 mm and 1 mm. Since the ultrasound transducer unit does not need to be reset after one position is finished, it can be moved to a working position of 5 mm by moving down by 2 mm after finishing working at 3 mm.

And step S130, controlling the driving mechanism to operate according to the motion parameters so as to drive the ultrasonic transduction unit to move to a working position corresponding to the target working depth.

In this embodiment, the driving mechanism operates according to the motion parameters, and further drives the ultrasonic transducer to move to a working position corresponding to the target working depth, where the working position refers to a position of the ultrasonic transducer in the ultrasonic therapeutic head, so that when the ultrasonic transducer is in the position, the energy focusing point for transmitting the ultrasonic waves is located at the target working depth.

As an alternative implementation mode, the driving mechanism is controlled to operate according to the motion parameters, and the ultrasonic transduction unit is driven to reach the working position corresponding to the target working depth; and after the corresponding working time of the working position, step S110 is executed.

The motion parameters comprise the moving distance of the ultrasonic transduction unit from the current position to the working position corresponding to the target working depth; and further generates a code executable by the drive mechanism controller based on design parameters of the drive mechanism itself.

As another alternative, the driving mechanism is controlled to operate according to a first part of the motion parameter, the ultrasonic transduction unit is driven to reach a working position corresponding to the first target working depth, and after the working position works for a corresponding working time, the driving mechanism is controlled to operate according to a second part of the motion parameter, and so on.

As another alternative embodiment, the driving mechanism is controlled to operate according to the motion parameters, and the ultrasonic transduction unit is driven to reciprocate between the first working position and the second working position corresponding to the target working depth.

Optionally, step S130 includes:

step S131, controlling the driving mechanism to drive the ultrasonic transduction unit to the working position according to the motion parameters, wherein when the driving mechanism is in displacement, the ultrasonic transduction unit is controlled to stop outputting ultrasonic waves;

In this embodiment, the ultrasonic transducer may terminate the output or continue the output when the driving mechanism is displaced. The displacement of the driving mechanism means that the driving mechanism is positioned in the vertical direction, so that the ultrasonic transduction unit is driven to adjust the working position.

Step S132, after the working time is worked at the working position, the step of determining the target working depth according to the input information is re-executed.

As an optional implementation manner, the driving mechanism carries out displacement according to the motion parameters, so that the ultrasonic transduction unit is driven to reach a working position corresponding to the target working depth, when the ultrasonic transduction unit is positioned at the working position and the ultrasonic treatment head begins working close to the target area, the ultrasonic transduction unit emits an ultrasonic energy gathering point, and the distance from the skin surface is a numerical value corresponding to the target working depth. The driving mechanism stops outputting ultrasonic waves during the moving process. When the timing device detects that the time for the ultrasonic transducer unit to emit ultrasonic waves at the working position satisfies the working time, step S110 is repeatedly performed.

For example, the target working depth corresponding to the current motion parameter is 3mm (millimeter), the working time is 1 minute, the driving mechanism is controlled to move according to the motion parameter, and then the ultrasonic transduction unit is driven to move to the working position corresponding to 3mm, and after the ultrasonic transduction unit works at the working position for 1 minute, the ultrasonic wave is stopped from being output, and the next target working position is obtained.

Optionally, the control method of the ultrasonic treatment head further includes:

step S1, determining the attaching state of the ultrasonic treatment head and a target area according to the state data of the ultrasonic treatment head;

in this embodiment, the target region is a region to be treated, for example, an abdomen, a leg, or the like, and the shape thereof may be irregular. The status data includes, but is not limited to, sensor data of the ultrasound therapy head, such as displacement velocity, displacement distance, fit status, etc.

As an alternative embodiment, sensor data of the ultrasound therapy head is acquired, and whether the ultrasound therapy head is attached to the target area is determined based on the sensor data.

For example, a preset area on the ultrasonic treatment head may be obtained, then the bonding area between the ultrasonic treatment head and the target area may be determined, and the bonding state may be determined according to the ratio of the bonding area to the preset area.

Step S2, determining the displacement state of the ultrasonic treatment head;

in this embodiment, the displacement state refers to a displacement state of the ultrasound therapy head on the approximately horizontal plane of the target region, and the displacement state includes, but is not limited to, a displacement speed, and a displacement acceleration.

As an alternative embodiment, the displacement speed of the ultrasound therapy head is determined from the status data.

And step S3, when the attaching state and/or the displacement state does not meet the working requirement, controlling the ultrasonic transduction unit to stop outputting energy.

In this embodiment, for safety reasons, corresponding operation requirements are set for the attaching state and the displacement state. The energy here includes, but is not limited to, ultrasound. Outputting energy when the treatment head is not attached to the target area can cause the energy concentration point to be in a non-working position with serious consequences. The output of energy when the treatment head is stationary can cause heat to build up at a point, again with serious consequences. Therefore, in this embodiment, the ultrasonic transducer unit outputs ultrasonic energy when it is determined that the ultrasonic treatment head is attached to the target region and the ultrasonic treatment head is in a moving state.

As an alternative embodiment, the ultrasonic transduction unit is controlled to stop outputting energy when at least one of the fitting state and the displacement state does not meet the operation requirement.

In an exemplary embodiment, when the proportion of the bonding area in the bonding state is smaller than a preset threshold value or the displacement speed in the displacement state is smaller than a preset threshold value, at least one of the two is established, the ultrasonic transduction unit is controlled to stop outputting energy.

As an alternative embodiment, the method is used for controlling an ultrasonic treatment head, the ultrasonic treatment head comprises an ultrasonic transduction unit and a driving mechanism, the driving mechanism is arranged outside a shell of the ultrasonic treatment head, and the driving mechanism drives the ultrasonic transduction unit to move in a direction far away from or close to a treatment window. The treatment window is the contact surface of the ultrasonic treatment head and the target area.

Based on the first embodiment, a second embodiment of the present application provides a control method of an ultrasonic treatment head, referring to fig. 6, step S130 further includes:

step S210, determining the displacement range of the driving mechanism according to the motion parameters;

In this embodiment, when the operation mode of the ultrasonic treatment head is the reciprocation, the target operation depth is a plurality of values or a range of values. The displacement range refers to the depth interval that the ultrasound therapy head needs to sweep in one operation.

As an alternative embodiment, the displacement range is determined according to the value interval corresponding to the motion parameter.

As another alternative implementation manner, according to n values corresponding to the motion parameters, a value interval is generated according to two values adjacent to each other in value size, and then n-1 value intervals are generated; and screening out the numerical value intervals which do not need to be scanned, and determining the displacement range according to the screened numerical value intervals.

Illustratively, values of 1mm, 2mm, 3mm,4mm, and 5mm are obtained, and value intervals of 1-2,2-3,3-4, and 4-5 are determined; the range of the displacement is determined to be 1mm to 3mm and 4mm to 5mm when the numerical intervals required to work are determined to be 1-2,2-3 and 4-5.

Step S220, matching corresponding displacement speeds according to the displacement ranges;

in this embodiment, considering that the points swept by the ultrasonic transducer unit are heated uniformly during the reciprocating motion, the displacement speed of the driving mechanism during the reciprocating motion may be a fixed value, a value that varies with the displacement range, or a value that matches the displacement speed of the ultrasonic treatment head in the target area.

As an optional implementation manner, a displacement range is determined, and a displacement speed corresponding to the displacement range is determined according to a preset association relation between the displacement range and the displacement speed. Before step S220, an association relationship between the displacement range and the displacement speed may be established in advance according to the historical treatment data and the treatment effect.

Optionally, the sign information of the target area can be obtained, and the association relationship is adaptively adjusted according to the sign information, so that for the current person to be treated, the adjusted displacement speed is used in the displacement range, and the optimal treatment effect can be achieved.

As another alternative, the displacement speed may be a fixed value, which is determined by the input information. But may also be generated from historical data.

Optionally, step S220 further includes:

step S221, obtaining the horizontal displacement speed of the ultrasonic transduction unit;

in the present embodiment, the displacement speed of the ultrasonic transduction unit in the horizontal direction is used as the horizontal displacement speed.

As an alternative embodiment, the displacement speed of the therapeutic head in the horizontal direction is determined according to the data acquired by the sensor of the ultrasonic therapeutic head, and the horizontal displacement speed of the ultrasonic therapeutic head is taken as the horizontal displacement speed of the ultrasonic transducer unit because the ultrasonic transducer unit moves in the vertical direction in the therapeutic head.

Step S222, obtaining a displacement speed corresponding to the displacement range, wherein the direction of the displacement speed is consistent with the movement direction of the driving mechanism;

step S223, correcting the displacement speed according to a preset displacement model and the horizontal displacement speed.

In the present embodiment, the displacement range has a displacement speed associated therewith, which is a moving speed of the ultrasonic transduction unit in the vertical direction. And then the displacement speed in the vertical direction is adjusted according to the horizontal displacement speed, and the displacement speed executed by the final driving mechanism is determined. I.e. the displacement speed will be adjusted as the horizontal displacement speed of the ultrasound therapy head in the target area changes.

As an alternative embodiment, determining a displacement speed matched with the currently executed displacement range according to the currently executed displacement range; substituting the displacement speed and the horizontal displacement speed into a preset displacement model, and determining the adjusted displacement speed. The displacement speed in the vertical direction is adjusted according to the horizontal displacement speed, so that the time for collecting energy at each point is the same as much as possible, and each point in the displacement range is heated uniformly.

Exemplary, a simulation model is established according to historical data, and the treatment effect is determined for the reciprocating motion in the same displacement range under the conditions of simulating different displacement speeds and horizontal displacement speeds; and selecting proper displacement speed and horizontal displacement speed according to the treatment effect. Wherein the criterion for the therapeutic effect is that each point in the displacement range is heated as uniformly as possible.

And step S230, controlling the driving mechanism to move according to the displacement speed and the displacement range so as to drive the ultrasonic transduction unit to reciprocate in a section corresponding to the working position according to the displacement speed.

As an alternative implementation mode, the driving mechanism is controlled to move according to the motion parameters so as to drive the ultrasonic transduction unit to reciprocate in a thickness interval corresponding to the displacement range according to the displacement speed.

Optionally, the displacement speed is influenced by both the displacement range and the horizontal displacement speed.

Alternatively, the ultrasonic transduction unit continuously outputs energy during the reciprocation of the ultrasonic transduction unit. Compared with the mode of working at fixed depth, the ultrasonic wave is continuously output during reciprocating motion, so that energy points are gathered between two adjacent target working depths, and the treatment effect is remarkably improved.

The technical scheme provided by the embodiment of the application at least has the following technical effects or advantages:

the displacement range of the driving mechanism is determined according to the motion parameters, so that the displacement speed matched with the displacement range is determined, and the displacement speed is the displacement speed in the vertical direction; and controlling the driving mechanism to move in a displacement range according to the displacement speed so as to drive the ultrasonic transduction unit to reciprocate in a section corresponding to the working position according to the displacement speed. Therefore, the technical problem that the treatment effect is poor in the range within the depth caused by the fact that the fixed depth can only be treated in the related technology is effectively solved, and the treatment effect is further improved.

When the current working depth is equal to the target working depth, the ultrasonic treatment head can control the ultrasonic energy conversion unit to emit energy.

As an alternative embodiment, the built-in parameters of the ultrasonic transduction unit are acquired, and the depth of focus of the ultrasonic transduction unit is determined according to the built-in parameters.

When the ultrasonic transduction unit is in the initial working position, the current working depth of the ultrasonic transduction unit is equal to the target working depth.
