Description

Focused ultrasound treatment head and focused ultrasound treatment method Technical field

The present invention relates to the field of medical beauty, and more specifically to a focused ultrasound treatment head and a focused ultrasound treatment method.

Background technique

Focused ultrasound is one of the mainstream technologies in the field of medical beauty, fat reduction and body shaping. Its basic principle is to use a positioning system to emit focused ultrasound waves of a specific frequency from outside the body to a certain fat layer under the dermis. The mechanical force of focused ultrasonic cavitation effect breaks the fat cell membrane, causing the fat cells to be broken, dissolved and emulsified. After the inflammatory reaction mechanism, broken fat cells will release a large amount of triglycerides, which are hydrolyzed by lipoprotein lipase into free fatty acids and glycerol, and then they are gradually absorbed by the body sculptor's own capillaries and lymphatic vessels, and finally passed through the liver or other parts of the body for metabolism. Usually, the goal of body shaping and beauty is gradually achieved within 4-8 weeks.

It has been recognized that the accuracy of the positioning relationship between the treatment head that emits focused ultrasound and the target part of the body shaping person or the treatment area will directly affect the safety and effectiveness of body shaping. In focused ultrasound treatment, in order to ensure that the abdomen, flanks, back, face, neck, limbs and other treatment areas are uniformly affected by focused ultrasound, the distance between each treatment point is required to be as uniform as possible and the treatment points are as uniform as possible Cover the entire treatment area. In addition, the same treatment point cannot be irradiated multiple times, otherwise the dose may be too high, which may lead to treatment safety issues.

The positioning system used during treatment is one of the key technologies for non-invasive body shaping using focused ultrasound. The treatment depth (Z direction) is determined by the focused ultrasound piezoelectric ceramic plate and related vertical mechanical structures. There are currently two methods for positioning the treatment head on the surface of the treatment area (XY direction). The first is to manually use a marker pen to draw squares, etc. on the area to be treated. This method is more time-consuming and less accurate. The second is to set up an additional imaging system directly above the treatment area (about 1 meter away) to locate, indicate and record the relevant area. However, this method will make the entire system too large and complex, and the cost will be high.

Next, exemplary embodiments of the focused ultrasound treatment head 1 integrated with the photoelectric positioning system 2 of the present invention and the method of using the focused ultrasound treatment head 1 to perform focused ultrasound treatment will be described with reference to FIGS. 1 to 7 . The focused ultrasound treatment head 1 can be used in non-invasive body shaping treatment for the body shaping person 3 to perform fat reduction treatment on specific body parts of the body shaping person 3, such as the abdomen, flanks, back, face, neck, limbs, etc. .

Referring to Figures 1 to 4, the treatment head 1 may have an active part 4 for emitting focused ultrasound or focused ultrasound energy (hereinafter referred to as focused ultrasound) to the area 10 to be treated on the body shaper 3 and an indicator with an indicator panel 6 Part 5. The active part 4 and the indicating part 5 can be provided with a common housing 7 and can be connected to each other by a neck part 8 of the housing 7 . The active part 4 and the indicating part 5 of the treatment head 1 may be arranged parallel to each other. In other embodiments, the active part 4 and the indicating part 5 of the treatment head 1 may also be configured adjacent to each other instead of being spaced apart from each other.

The active part 4 of the treatment head 1 can have a generally drum-like shape and therefore has a rounded active end face 9 facing the body shaper 3 (downward in the figure) in the state of use, against which the active end face 9 can abut during treatment. 3 on the area to be treated 10 and continuously move thereon. The housing parts of the housing 7 surrounding the active part 4 can be two-piece and can be connected together by screws 11 arranged one after the other around. The active part 4 of the treatment head 1 can have a centrally arranged pressure ring 12 on its active end face 9 radially inside the screw 11 , which pressure ring 12 can be detachably connected to the housing 7 via a screw 13 .

The active part 4 of the treatment head 1 may have a piezoelectric ceramic plate 14 for converting electrical signals into ultrasound and a liquid coupling medium 15 for forming an ultrasound propagation path (see Figure 3). The radially inner region of the active end face 9 of the pressure ring 12 can be formed by a plastic film that seals the coupling medium 15 toward the outside and can form a circular energy coupling surface region 16 . The focused ultrasound emitted by the treatment head 1 can pass through the energy coupling surface area 16 and can form an energy focusing area or focus area 17 at a certain distance in front of the center of the energy coupling surface area 16, that is, the penetration distance L, that is, there is an area surrounding the focus. The area of relatively strong energy may be a roughly spherical or ellipsoidal area, and its central cross-sectional area may be a circular area with a diameter of 1 mm to 6 mm, for example, 4 mm. The penetration distance L can be predetermined when designing the treatment head 1 .

The active part 4 of the treatment head 1 may have a circular control end surface 18 , which may be opposite to the active end surface 9 and may face the indication part 5 . The treatment head 1 may have a transmit button 19 on the control end surface 18 of its active part 4, and the focused ultrasound can be emitted by manually operating the transmit button 19. In this embodiment, the launch button 19 may be mechanical. In addition, touch-sensitive buttons 19 for the digital display are also conceivable. The treatment head 1 can have an electrical connection 20 on the control end face 18 of its active part 4 on the side opposite the neck part 8 of the housing 7 , in which a cable 21 can be guided, which can include a power supply cable and /or signal line. The treatment head 1 can be electrically connected to an external host (not shown, which can also serve as a control system of the treatment head 1) via a cable 21 and can communicate with the host.

The active part 4 of the treatment head 1 can have a photoelectric positioning system 2, which can determine a specific point of the treatment head 1, specifically its energy coupling surface area 16, such as the center (i.e., the center of the circle) of the body shaping person 3 to be treated during treatment. Position information on the plane (ie, XY direction) where the area 10 is located (hereinafter also referred to as "on the area 10 to be treated"), such as plane position coordinates. The plane position coordinates of a specific point of the energy coupling surface area 16, such as the geometric center, can be The coordinates correspond to or are equal to the center of the focus area 17 of the focused ultrasound, that is, the plane position coordinate of the focus. The specific point of the energy coupling surface area 16 may coincide with the orthographic projection of the focus of the focused ultrasound on the energy coupling surface area 16 .

The photoelectric positioning system 2 may have multiple, in this embodiment, two photoelectric positioning modules 22, and each photoelectric positioning module 22 can independently measure its position information, such as XY plane position coordinates. Since the central axial area of the treatment head 1 is generally the energy emission area, the photoelectric positioning module 22 can only be placed at the edge of the treatment head 1 at a certain distance from the center. The photoelectric positioning module 22 may be disposed radially outside the energy coupling surface area 16 so as not to block the emission path of the focused ultrasound. The photoelectric positioning system 2 or its photoelectric positioning module 22 can also be disposed on other parts of the treatment head 1, such as a specially configured support area.

The photoelectric positioning system 2 or its photoelectric positioning module 22 can move close to the area to be treated 10 during treatment. Here, “adhering” can be understood as adhering to the area to be treated 10 or having a small distance therefrom, which distance can allow the photoelectric positioning system 2 or its photoelectric positioning module 22 to work normally or be positioned.

Referring to Figures 4 and 5, the photoelectric positioning module 22 may have an optical sensor 23, which may include a CMOS photoreceptor and a digital signal processor (DSP). The CMOS photoreceptor is a matrix composed of hundreds of photoelectric devices, which is used to capture the physical displacement of the treatment head 1. The optical sensor 23 can amplify the captured light signal and project it onto the CMOS matrix to form a frame, and then convert the framed image from the light signal into an electrical signal, and transmit it to a digital signal processor (DSP) for analysis and processing. After the digital signal processor (DSP) removes noise and analyzes the difference between adjacent frames, the resulting displacement information is transmitted to a specially equipped control system or transmitted to the host through the cable 21 in the electrical connector 20 .

The optoelectronic positioning module 22 can have an optical lens assembly 24 , which can be designed as a transparent light path block, and which optical lens assembly 24 can be arranged facing the external environment in the installed state. The optical lens assembly 24 may have a prism mirror 25 and a circular lens 26 . Circular lens 26 may be aligned with optical sensor 23 .

The photoelectric positioning module 22 may have an illumination device 27, such as a light emitting diode (LED) or a laser generator, which can illuminate the portion of the area to be treated 10 that is adhered to by the photoelectric positioning module 22 via the prism mirror 25 of the optical lens assembly 24.

The optoelectronic positioning module 22 may have a mounting frame 28 with a gap into which the optical lens assembly 24 may snap. The optical sensor 23 , the optical lens assembly 24 , the lighting device 27 and the optical sensor 23 can be embedded into the mating recess 29 at the active end of the treatment head 1 as a mounting block after being installed together. A cover 30 can also be provided for the photoelectric positioning module 22 , and the cover 30 can fix the photoelectric positioning module 22 in the treatment head 1 . The cover 30 may have apertures to illuminate and photograph the area 10 of the body shaper 3 to be treated.

The XY plane position coordinates of the center of the energy coupling surface area 16 or the center of the focus area 17 (or focus) of the treatment head 1 can be calculated through mathematical formulas through its own plane position coordinates measured by each photoelectric positioning module 22 . In this embodiment, the two photoelectric positioning modules 22 may be arranged radially opposite to the center of the energy coupling surface area 16 . Therefore, the two photoelectric positioning modules 22 may have the same radial distance from the center of the energy coupling surface area 16 and may be considered to be on a straight line. Therefore, the plane coordinates (x, y) of the center of the focus area 17 can be calculated from the coordinates of the two photoelectric positioning modules 22 themselves using the following formula:

x=(x1+x2)/2, y=(y1+y2)/2; where, x, y are the plane coordinates of the center of the focus area 17, x1, y1 and x2, y2 are the coordinates of the two photoelectric positioning modules 22 respectively. Plane coordinates.

In some embodiments, the two photoelectric positioning modules 22 can be distributed and installed on the active end surface 9 of the treatment head 1 in other positional relationships (for example, in terms of distance and angle) relative to the center of the energy coupling surface area 16 , while the focus area 17 The coordinates of the center position can be derived based on the geometric position relationship between the two photoelectric positioning modules 22 and the center of the energy coupling surface area 16 .

In some embodiments, the photoelectric positioning system 2 may also have more than two, for example, three photoelectric positioning modules 22 , and their geometric positional relationships relative to the center of the energy coupling surface area 16 are all known. A plane coordinate of the center of the focus area 17 can be derived from the plane coordinates of each two photoelectric positioning modules 22 , so more than two plane coordinates representing the center of the focus area 17 can be obtained. This is advantageous, on the one hand, by averaging a plurality of derived coordinates, more precise planar coordinates of the center of the focus area 17 can be obtained. These photoelectric positioning modules 22 can thus be calibrated to each other; on the other hand, in the event that one of the photoelectric positioning modules 22 fails, or when one of the photoelectric positioning modules 22 is accidentally lifted away from the treatment area 10 during treatment, the remaining Any two photoelectric positioning modules 22 can also calculate the plane coordinates of the center of the focus area 17 normally without causing the need for recalibration.

The indication part 5 of the treatment head 1 can indicate different information to the treatment head operator with its indication panel 6 according to different positions of the treatment head 1 on the treatment area 10 during treatment. The indication panel 6 may communicate with the host via the cable 21 and may be controlled by the host, or it may communicate with and be controlled by a control system within the treatment head.

The indicator panel 6 may have indicator lights of different colors, such as red lights, yellow lights, and green lights. When the treatment head 1 moves on the area to be treated 10 to a position where it is prohibited to emit focused ultrasound (such as the navel, corner of the eye, etc.), the red light can be on, and it is prohibited to emit focused ultrasound at this time; when the treatment head 1 moves on the area to be treated 10 When it reaches the position where emission of focused ultrasound is allowed but has been emitted, the yellow light can be on, and the focused ultrasound can no longer be emitted repeatedly at this time; when the treatment head 1 moves on the area to be treated 10 to a position where emission of focused ultrasound is allowed but has not yet been emitted, The green light can be on, this Focused ultrasound can be emitted or not emitted. Of course this is just an example of an instruction method. Other indication methods are also conceivable. For example, the indication panel 6 may be a digital display screen panel, on which different symbols, patterns, or colors may be displayed to indicate different positions of the treatment head 1 . In addition to visual instructions, auditory instructions or a combination of visual and auditory instructions are also conceivable.

With reference to Figures 6 and 7, the following uses the abdomen of the body shaping person 3 as an example of the area 10 to be treated to exemplarily introduce a method of using the focused ultrasound treatment head 1 to perform focused ultrasound treatment on the body shaping person. The treatment method may mainly include: Treatment area 10 position information collection stage and treatment stage.

First, the separation distance (emission step size M) between each treatment position can be input to the host (step S1). The emission step length M can be predetermined according to the body shaping user's needs, such as the number of focused ultrasound transmissions required. When the area of the area to be treated 10 is determined, the larger the step size M is selected, the fewer treatment points or treatment positions will be.

Next, the stage of collecting position information of the area to be treated in this method is introduced (step S2):

Move the treatment head 1 to a predetermined peripheral starting positioning point P1, and the host (it can also be a specially set up control system in the treatment head, the same below) records the coordinates of the initial positioning point P1 (here it can refer to the XY plane coordinates, the same below);

Move the treatment head 1 against the abdomen of the body shaper 3 to three other predetermined peripheral positioning points P2, P3, and P4, and the host records their coordinates respectively. Therefore, these four peripheral positioning points P1-P4 can Together, a quadrilateral, such as a rectangular (30cmx20cm for the abdomen) area to be treated 10 is defined;

Continue to move the treatment head 1 against the abdomen of the body shaping person 3 to the positioning point P5 of the prohibited emission area located in the navel area, and the host computer records its coordinates.

Thus, the position information collection of the area to be treated 10 on the abdomen of the body shaper 3 is completed and recorded by the host computer.

After obtaining these position information, the host computer automatically and virtually marks the allowed emission position 31 (shown with a "+" sign in the figure) and the prohibited emission position 32 of the focused ultrasound in the area to be treated 10 with a predetermined emission step size M. (shown as a black circle in the figure), where the spacing between the two allowed emission positions 31 may be one emission step M, and the prohibited emission position 32 may be a predetermined area surrounding the prohibited emission area positioning point P5, for example A circular area with a predetermined diameter with the emission-prohibited area positioning point P5 as the center.

Next, the treatment operation can be performed (S3).

Move the treatment head 1 against the abdomen of the body shaper 3 on the area to be treated 10. When the center plane coordinates of the focus area 17 of the treatment head 1 correspond to the allowed emission position 31, the indication panel 6 can, for example, indicate that the emission focus is allowed by a bright green light. Ultrasound, at this time the operator can press the transmission button 19 to allow the transmission of focused ultrasound, but can also ignore the instruction and not allow the transmission of focused ultrasound;

If the operator transmits focused ultrasound for treatment at the transmission-allowed position 31, the host re-marks this position as a position 33 that allows transmission and has transmitted focused ultrasound (shown with a "#" sign in the figure). Therefore, when the treatment head 1 subsequently moves to the position 33 again, the indication panel 6 may provide an indication by, for example, turning on a yellow light to prevent the operator from repeatedly emitting focused ultrasound to the position 33 again.

When the treatment head 1 moves against the abdomen of the body shaper 3 until the center plane coordinates of its focal area 17 correspond to the prohibited emission position 33, the indication panel 6 may, for example, indicate the prohibition of transmitting focused ultrasound by turning on a red light, so as to prohibit the operator from doing so. Position 33 emits focused ultrasound. Alternatively or additionally, the host computer can also be configured to temporarily deactivate the transmit button 19 , that is, even if the transmit button 19 is pressed at this time, the focused ultrasound will not be emitted.

The treatment process is executed in the above manner until the treatment is completed (step S6).

During treatment, if the treatment head 1 is accidentally lifted, the photoelectric positioning system 2 may lose the measurement data of continuous displacement (step S4). If the continuous displacement data is lost due to being lifted, the indication panel 6 can give the operator a corresponding indication that the position of the treatment head 1 needs to be recalibrated. At this time, before continuing treatment, the position of the treatment head needs to be recalibrated again. For example, the treatment head 1 is moved to the initial peripheral positioning point P1 again and calibrated (S5). Specifically, the host records again. The position information of the initial peripheral positioning point P1, and based on the relationship between the position information of this point P1 and the position information of other points (this has been automatically calculated by the host), restore all previously recorded data, which at least include the permission to launch And the fired position 33 and the fired and not yet fired position 31, the fired position 32 and so on. Afterwards, go to step S3 to continue the treatment process.

The advantages of the focused ultrasound treatment head 1 and the focused ultrasound treatment method of the present invention include, but are not limited to: with the help of the photoelectric positioning system 2 integrated on the treatment head 1, the location of the treatment head 1 on the area to be treated can be conveniently determined. position information, and the control system can control the indication part to give different corresponding prompt information to the operator according to different position information during treatment, so that the operator can selectively emit focused energy. This eliminates the existing manual marking of the area to be treated or the use of external additional imaging systems.
