Description

Cartridge for focused ultrasound device and focused ultrasound device comprising same

The present invention relates to a cartridge for a focused ultrasonic device and a focused ultrasonic device including the same.

Recently, interest in skin beauty and obesity treatment has been increasing day by day, and accordingly, various medical devices for skin beauty and obesity treatment are being developed. For example, various skin beauty medical devices are being developed for patients who want skin lifting or skin tightening procedures, and on the other hand, medical devices for treating obesity patients are being developed.

Among these medical devices, there are invasive medical devices that cut skin tissue, but as issues with the safety of the procedure and patient reluctance are being raised, non-invasive medical devices that can perform the procedure without cutting skin tissue are gradually gaining attention.

In line with this trend, development and research on non-invasive medical devices using Intensity Focused Ultrasound (IFU) (hereinafter referred to as “focused ultrasound devices”) are actively underway.

For example, there is a skin beauty focused ultrasound device that forms a thermal focal point of focused ultrasound within relatively shallow skin tissue to perform a skin lifting or skin tightening procedure, and there is a focused ultrasound device for obesity treatment that irradiates focused ultrasound to the subcutaneous fat layer to burn or melt and decompose fat tissue. In addition, focused ultrasound devices can be applied to various fields such as removing cancerous tissue, removing stretch marks, and treating hyperhidrosis or bromhidrosis.

Meanwhile, the component that actually generates ultrasound in a focused ultrasound device may be referred to as a "transducer," and when this transducer is placed in close contact with a treatment area and ultrasound is irradiated, a thermal focus can be formed on a specific tissue such as a muscle or fat layer, thereby regenerating or removing the tissue.

However, since the location (depth) of the distribution of subcutaneous fat is different for each individual, there is a problem in that when the probe is simply placed in contact with the skin surface and operated as in the conventional technique, unnecessary nerves or muscles other than subcutaneous fat are stimulated, causing side effects from the procedure.

To solve this problem, a technology for allowing the ultrasonic wave providing unit to move in one direction is introduced in patent document 1.

The focused ultrasound device (1000) of the present invention may be a medical device that performs various procedures using focused ultrasound (IFU: Intensity Focused Ultrasound). The intensity of the focused ultrasound may be configured in various ways. For example, the focused ultrasound device (1000) may provide high intensity focused ultrasound (HIFU: High Intensity Focused Ultrasound) with a relatively high intensity of focused ultrasound, or may provide low intensity focused ultrasound (LIFU: Low Intensity Focused Ultrasound) with a relatively low intensity.

In the following examples, the focused ultrasound device (1000) is described as a skin beauty focused ultrasound device for skin lifting or skin tightening procedures, but is not limited thereto, and can be applied to various fields, such as a focused ultrasound device for obesity treatment to burn or melt and decompose fat tissue, a focused ultrasound device for treatment of cancer tissue removal, removal of stretch marks, hyperhidrosis or bromhidrosis, etc.

Referring to FIGS. 1 to 8, a cartridge (100) for a focused ultrasonic device may include a cartridge body (110) and an ultrasonic wave providing unit (120). In another embodiment, the cartridge (100) for a focused ultrasonic device may further include a power transmission unit (130) and an actuator (140).

The cartridge body (110) may have an accommodation space (S1, S2, S3) formed therein that can accommodate a medium. For example, the cartridge body (110) may be provided in a cylindrical shape with an accommodation space (S1, S2, S3) formed therein, and the accommodation space (S1, S2, S3) may be filled with various components and a medium having good ultrasonic transmission characteristics.

In this way, as the medium is filled inside the cartridge body (110), the focused ultrasound output from the ultrasonic wave providing unit (120) described below can be smoothly transmitted to the outside of the cartridge body (110). In addition, the medium can also cool the heat generated when the ultrasonic wave providing unit (120) generates the focused ultrasound. For example, the medium can be formed of water.

In one embodiment, the cartridge body (110) may include a first wall (111), a second wall (112), and a cover portion (113).

In one embodiment, the first wall (111) may be formed in a column shape with an open top, and the second wall (112) may be formed in a column shape with an open top and provided on the inside of the first wall (111).

In one embodiment, the first wall (111) may form an outer appearance of the cartridge body (110), but is not limited thereto. The first wall (111) may have an open upper portion to form an opening (110b) in the upper portion of the cartridge body (110).

In one embodiment, an ultrasonic wave providing unit (120) described later is arranged inside the second wall (112), and the second wall (112) may be arranged on the inside of the first wall (111) and spaced apart from the first wall (111). That is, the cartridge body (110) may be provided as a double-wall structure by the first wall (111) and the second wall (112). In addition, one side of the second wall (112) may be formed to protrude from the first wall (111), thereby forming a protruding area (112a) at the bottom of the cartridge body (110). A space in which the ultrasonic wave providing unit (120) described later can move may be secured inside the cartridge body (110) through this protruding area (112a). In addition, one end of the protruding section (112a) is provided with a through hole (112b) through which ultrasonic waves pass, and this through hole (112b) is sealed by a window (150), so that ultrasonic waves can be transmitted through the window while preventing the medium inside the receiving space from leaking out of the cartridge body.

In one embodiment, the cover member (113) is coupled to the first wall member (111) and the second wall member (112) and may be provided to cover the upper portion of the first wall member (111) and the upper portion of the second wall member (112).

In one embodiment, the receiving space of the cartridge (100) for the focused ultrasound device may be divided into a first receiving space (S1), a second receiving space (S2), and a third receiving space (S3) by a first wall (111), a second wall (112), and a partition wall.

　

In one embodiment, the first receiving space (S1) may mean a space surrounded by a cover portion (113), a second wall (112), and a window.

In one embodiment, the second receiving space (S2) and the third receiving space (S3) may mean a space surrounded by a cover portion (113), a first wall (111), and a second wall (112), and may be divided into the second receiving space (S2) and the third receiving space (S3) by a partition wall having one end coupled to the first wall (111) and the other end coupled to the second wall (112). In one embodiment, the partition wall may be implemented in a manner in which one of the first wall (111) and the second wall (112) extends toward the other. In one embodiment, the partition wall may include a first partition wall (112-1) and a second partition wall (112-2).

In one embodiment, the second wall (112) may be provided with a first recessed portion (112c) and a second recessed portion (112d). The first recessed portion (112c) and the second recessed portion (112d) may be formed by recessing a portion of the upper surface (112-9) of the second wall (112) downward. In addition, a medium and air may move between the first receiving space (S1) and the second receiving space (S2) through the open space between the first recessed portion (112c) and the cover portion (113).

In another embodiment, the first inlet portion (112c) and the second inlet portion (112d) may be provided at a height that does not contact the cover portion (113), but in this case, the possibility of bubbles being generated during the medium injection process may be relatively high.

In one embodiment, the cover portion (113) may be provided with a first passage (113-1) and a second passage (113-2), wherein the first passage (113-1) connects the outside of the cover portion (113) and the second receiving space (S2), and the second passage (113-2) connects the outside of the cover portion (113) and the third receiving space (S3).

In one embodiment, when the first inlet portion (112c) is positioned at the top and the through hole (112b) is positioned at the bottom, if a medium is injected into the first passage (113-1), the medium filled in the second receiving space (S2) may overflow into the first receiving space (S1) through the first inlet portion (112c), so that the first receiving space (S1) may also be filled with the medium. At this time, if the medium continues to be injected into the first passage (113-1), the medium filled in the first receiving space (S1) may overflow into the third receiving space (S3) through the second inlet portion (112d), so that the third receiving space (S3) may also be filled with the medium, and ultimately, the medium filled in the third receiving space (S3) may be discharged to the outside of the cover portion (113) through the second passage (113-2). When the first passage (113-1) and the second passage (113-2) are sealed at the point where the medium begins to be discharged in this way, the insides of the first receiving space (S1), the second receiving space (S2), and the third receiving space (S3) are filled with the medium.

In one embodiment, the upper surface (112-9) of the second wall (112) is closely coupled to the lower surface of the cover portion (113), and the first inlet portion (112c) is spaced apart from the lower surface of the cover portion (113) to allow a medium and air to flow between the first receiving space (S1) and the second receiving space (S2).

In one embodiment, the upper surface (112-9) of the second wall (112) is closely coupled to the lower surface of the cover portion (113), and the second inlet portion (112d) is spaced apart from the lower surface of the cover portion (113) to allow medium and air to flow between the first receiving space (S1) and the third receiving space (S3).

In one embodiment, a groove (113-9) corresponding to the shape of the upper surface (112-9) of the second wall (112) is provided on the lower surface of the cover part (113), and the upper part of the second wall (112) can be inserted into the groove (113-9) to ensure airtightness.

In one embodiment, the first inlet portion (112c) may be positioned between the first passage (113-1) and the first bulkhead (112-1). Additionally, the second inlet portion (112d) may be positioned between the second passage (113-2) and the second bulkhead (112-2).

Accordingly, the medium injected into the first passage (113-1) can be moved to the first receiving space (S1) through the first inlet (112c) after filling the second receiving space (S2).

In one embodiment, the cover part (113) may be provided with a wire insertion hole (113-7) so that an external power source or signal may be applied to the ultrasonic wave providing part (120). In addition, so that the cover part (113) may be firmly connected to the second wall (112), fastening units (113-4, 113-5) may be screw-connected to the first fastening hole (112-4) and the second fastening hole (112-5) provided in the second wall (112) and the like by penetrating the cover part (113).

Meanwhile, when the medium is reduced in the process of using the ultrasonic device, air may exist in the receiving space, and when this air is located between the ultrasonic provider (120) and the window (150), ultrasonic waves are not transmitted smoothly. However, since the cartridge (100) for the focused ultrasonic device according to one embodiment of the present invention includes a first inlet portion (112c) and a second inlet portion (112d) provided at the joining portion of the second wall (112) and the cover portion (113), even if the position of the window (150) is changed from facing downward to facing upward, the air that was inside the first receiving space (S1) moves to the second receiving space (S2) through the first inlet portion (112c) during the position change process, and as a result, the space between the ultrasonic provider (120) and the window (150) can be maintained in a state where the medium is fully filled.

In one embodiment, the first wall (111) may be provided with a first valley portion (111a) and a second valley portion (111b) whose gaps with the second wall (112) are minimized. At this time, the first valley portion (111a) may be provided between the first passage (113-1) and the first inlet portion (112c), and the second valley portion (111b) may be provided between the second passage (113-2) and the second inlet portion (112d). Referring to FIGS. 4 to 6, it can be understood that the first fastening hole (112-4) may protrude toward the first wall (111) to implement the first valley portion (111a), and the protrusion portion (112-6) may protrude toward the first wall (111) to implement the second valley portion (111b). In Fig. 6, arrows schematically illustrate the flow of medium. When the first to third receiving spaces (S1, S2, S3) are filled with medium, bubbles located in the second receiving space (S2) have difficulty passing through the first valley portion (111a), and bubbles located in the third receiving space (S3) have difficulty passing through the second valley portion (111b). Therefore, the inflow of bubbles from the outside of the first receiving space (S1) to the inside of the first receiving space (S1) can be minimized.

In one embodiment, a cover part (113) may be provided in an opening part (110b) formed in the upper part of the cartridge body (110) to cover the opening part (110b). A guide part (113a) that guides the movement of a power transmission part (130) described later may be provided on one side of the cover part (113). In addition, a circuit board (160) may be coupled to the cover part (113).

In one embodiment, the cartridge body (110) may be formed integrally or may be formed by multiple structures that are separable from each other. That is, the first wall (111), the second wall (112), and the cover part (113) may be provided to form a single body, or the first wall (111), the second wall (112), and the cover part (113) may be formed to be separable from each other.

In one embodiment, the ultrasound provider (120) is provided to be unidirectionally movable in the first receiving space (S1) and can generate focused ultrasound. In this way, since the ultrasound provider (120) is provided to be unidirectionally movable within the cartridge body (110), focused ultrasound can be provided at a desired point. That is, by moving the ultrasound provider (120) to a desired position, the position of the focus of the focused ultrasound can be adjusted, thereby providing focused ultrasound from the surface of the skin to a desired depth.

In one embodiment, the ultrasound providing unit (120) may include a transducer (121) and a cover unit (122).

In one embodiment, the transducer (121) may be supplied with power to convert electrical energy into ultrasonic energy. For example, the transducer (121) may be formed of a circular ultrasonic ceramic, and when supplied with power in a pulse form to generate ultrasonic waves, the ultrasonic waves may be focused to form a focus having high-intensity energy at a specific location. Accordingly, when the focused ultrasonic waves are irradiated on the skin of a subject, heat is generated at the focus due to the thermal effect of the ultrasonic waves, and when such ultrasonic waves are provided to the skin of the subject, treatments such as skin lifting or skin tightening become possible.

In one embodiment, the cover portion (122) is connected to one side of the power transmission portion (130) and can support and cover the transducer (121). For example, the cover portion (122) can be formed in a hollow cylindrical shape with one side open, and a step that can support the transducer (121) can be formed on the inner surface.

In one embodiment, the power transmission unit (130) is connected to one side of the ultrasonic provider unit (120) and can transmit power to the ultrasonic provider unit (120). For example, the power transmission unit (130) can be screw-coupled to an actuator (140) described below and can move upward or downward in the drawing to transmit power to the ultrasonic provider unit (120). At this time, a position detection sensor (not shown) consisting of a hall sensor, an infrared sensor, a photo sensor, etc. is installed in the power transmission unit (130) to detect a change in the position of the ultrasonic provider unit (120).

In one embodiment, the power transmission unit (130) may be formed of a body unit (131) and a power transmission bar (132).

In one embodiment, the body portion (131) may have a coupling groove formed lengthwise so that it can be screw-coupled with a rotational axis of an actuator (140) described later on one side. That is, screw threads may be formed on the inner surface of the body portion (131) on which the coupling groove is formed.

In one embodiment, the power transmission bar (132) may be formed to protrude from one side of the body portion (131), and the cover portion (122) of the ultrasonic wave providing portion (120) may be connected to the protruding end.

In one embodiment, the actuator (140) is connected to the power transmission unit (130) and can rotate at a preset angle to move the power transmission unit (130) upward or downward. In this embodiment, the actuator (140) is illustrated and described as a rotatable motor, but any actuator that can move the power transmission unit (130) upward or downward may be applied. For example, the actuator (140) may be formed of a solenoid, an electromagnet, a slide motor, or the like.

In one embodiment, the actuator (140) can be prevented from moving toward the ultrasonic wave providing unit (120). For example, a portion of one side of the cartridge body (110) facing the actuator (140) can be formed to form a step, and the actuator (140) can be prevented from moving toward the ultrasonic wave providing unit (120) by this step.

In one embodiment, the actuator (140) may be formed of a motor (141) and a connecting member (142).

In one embodiment, the motor (141) may be fixed to the cartridge body (110), and may be provided with a structure in which the motor (141) is coupled to a fixed frame (143) coupled to a cover part (113). For example, the motor (141) may be formed as a step motor capable of forward and reverse rotation. Here, since the motor (141) is operated by electricity, it is necessary to prevent a medium from flowing into the motor (141). To this end, a sealing member (170) may be installed between the cover part (113) and the power transmission part (130). This sealing member (170) may be provided as one, but may also be provided as a plurality in order to improve sealing efficiency.

In one embodiment, the connecting member (142) may have an inner surface fixed to the shaft (141a) of the motor (141) and an outer surface screw-connected to the power transmission member (130). For example, the connecting member (142) may be formed in a pipe shape with threads formed on the outer surface.

Accordingly, when the motor (141) rotates in one direction, the power transmission unit (130) that is screw-connected to the connecting member (142) moves downward in the drawing, and when it rotates in the other direction, the power transmission unit (130) can move upward. Then, the ultrasonic wave providing unit (120) connected to the power transmission unit (130) can also move upward or downward by a desired distance between the maximum value (D1) and the minimum value (D2) illustrated in FIG. 3. In other words, the focus (10, 10-1) of the focused ultrasound can move by a length equal to D1 minus D2.

According to one embodiment of the present invention, a through hole (112b) is provided on one side of the cartridge body (110), and the through hole (112b) can be sealed with a window (150). Accordingly, the medium can be maintained in a state of being confined inside the cartridge body (110). In addition, focused ultrasound generated from the ultrasonic wave providing unit (120) passes through the window (150) and is transmitted to the outside of the cartridge body (110). For example, the window (150) can be formed of a material and thickness that can be as little affected as possible when the focused ultrasound passes through it. That is, the window (150) can be formed of a material that has a small degree of change in intensity, characteristics, direction, etc. of the focused ultrasound and the ultrasonic wave providing unit (120) passing through the window (150).

Referring to FIGS. 9, 10, and 11, a focused ultrasound device (1000) according to one embodiment of the present invention may be implemented by coupling the aforementioned focused ultrasound device cartridge (100) to a housing (200). In one embodiment, the housing (200) may be implemented in a form in which a focused ultrasound device cartridge (100), a control unit (230), a power supply unit (240), etc. are accommodated between a first housing (210) and a second housing (220). In one embodiment, the first housing (210) may be provided with a first cartridge receiving portion (211) and a first handle portion (212), and the second housing (220) may be provided with a second cartridge receiving portion (221) and a second handle portion (222). At this time, the space between the first receiving portion (211) and the first handle portion (212) can be folded, and accordingly, the process of the user holding the housing (200) with his/her hand and touching the window (150) to the user's face to perform the procedure can be performed comfortably and efficiently.

In one embodiment, a cartridge (100) for a focused ultrasound device may be accommodated between a first cartridge receiving portion (211) and a second cartridge receiving portion (221). In addition, a control portion (230), a power supply portion (240), etc. may be accommodated between a first handle portion (212) and a second handle portion (222). Since the portion where the first handle portion (212) and the second handle portion (222) are combined is a portion that is gripped by a user, it may be called a handpiece. Meanwhile, although not illustrated, a display device (not illustrated) that provides information related to the procedure to a practitioner, and an input device (not illustrated) that receives a command from a practitioner may be provided in the housing (200).

In one embodiment, a multifunctional lid (300) may be coupled to the window (150) side of a cartridge (100) for a focused ultrasound device. The multifunctional lid (300) is provided so as to expose the window (150) to the outside. In addition, the multifunctional lid (300) may generate at least one of a high-frequency current, a microcurrent, and an LED light.

In one embodiment, a focused ultrasound device (1000) can be configured to simultaneously or separately provide heat and infrared rays by irradiating light from R, G, and B light-emitting diodes (LEDs), while allowing near-infrared rays generated from infrared (IR) light-emitting diodes to penetrate deep into the skin of the human body to increase the temperature of the epidermal layer as well as the dermal layer, thereby promoting expansion of microvessels and blood circulation, thereby sufficiently supplying blood volume and oxygen.

For example, red series LEDs can provide the effects of alleviating flushing/erythema, alleviating skin discoloration, producing collagen, improving aging spots, resisting UV rays, treating atopic dermatitis, alleviating skin inflammation, acne, regenerating scars, improving skin wrinkles, regenerating cells, healing wounds, and reducing pain. Green series LEDs can provide the effects of soothing the skin and antibacterial, and blue series LEDs can provide the effects of sterilizing infectious viruses, suppressing sebum, preventing skin infections, regenerating scars, and removing warts.

In one embodiment, the focused ultrasound device (1000) can be implemented to enable microcurrent generation, high-frequency current generation, microcurrent measurement, etc.

As described above, the cartridge (100) for the focused ultrasound device can provide the focus of the focused ultrasound at a desired depth depending on the skin condition of an individual, as the ultrasound providing unit (120) within the cartridge body (110) is formed to be able to move toward the window (150) or toward the actuator (140).

In addition, since the focus position of the focused ultrasound is adjusted, it can deteriorate or decompose the epidermis, dermis, subcutaneous fat, SMAS (muscle fiber layer), etc. distributed in the exact desired location, thereby improving the accuracy of the procedure, and by not stimulating unnecessary nerves or muscles as in the past, it can reduce side effects from the procedure and improve the reliability of the device.

The power supply unit (240) can provide electricity to the cartridge (100) for the focused ultrasonic device. Accordingly, the cartridge (100) for the focused ultrasonic device can receive electricity and drive the ultrasonic providing unit (120) and the actuator (140).

The control unit (230) can detect a change in the position of the ultrasonic wave providing unit (120) and control the rotation amount of the actuator (140). For example, the control unit (230) can detect a change in position using a position detection sensor provided in the power transmission unit (130), and control the rotation amount of the actuator (140) using this change amount.

The focused ultrasound device (1000) according to the present invention can be configured to operate by receiving power through a wire or by receiving power wirelessly without a separate wire.

Meanwhile, the focused ultrasound device (1000) can be mounted on a tray (2000).

　

The operation of the focused ultrasonic device (1000) according to the present invention will be described with reference to FIGS. 1 to 11 as follows.

First, the focused ultrasound device (1000) mounted on the tray (2000) is separated, and then the window (150) is placed in contact with the skin. Then, the actuator (140) is rotated in one direction so that focused ultrasound can be provided at a desired location. Although not shown, the housing (200) may be provided with an input unit for controlling the operation of the actuator (140).

In this embodiment, the window (150) is first brought into contact with the skin and then the actuator (140) is driven. However, it is also possible to first drive the actuator (140) and then bring the window (150) into contact with the skin.

When the actuator (140) is rotated in one direction in this way, the power transmission unit (130) screw-coupled to the actuator (140) and the ultrasonic wave providing unit (120) coupled to the power transmission unit (130) move toward the window (150) as illustrated in Fig. 3(b). When the ultrasonic wave providing unit (120) moves toward the window (150) in this way, the focus (10-1) of the focused ultrasound is positioned lower by D1-D2 than the focus (10) of the focused ultrasound illustrated in Fig. 3(a), so that the focused ultrasound can be provided to a deeper area from the surface of the skin.

Conversely, if the location of the focused ultrasound is too deep, when the power transmission unit (130) is rotated in the opposite direction, the focus (10) of the focused ultrasound is focused on the upper side as illustrated in Fig. 3(a). This focus of the focused ultrasound can be freely focused at various depths by the power transmission unit (130).

After the procedure is completed, the focused ultrasound device (1000) can be placed back on the tray (2000), and the power supply unit of the focused ultrasound device (1000) placed on the tray (2000) can be wirelessly charged.

In one embodiment, the medium of the first receiving space (S1) may be reduced during the use of the focused ultrasonic device (1000). In this case, if ultrasonic waves are generated while bubbles are positioned in the area between the ultrasonic generator (120) and the window (150), the transmission rate of the ultrasonic waves may be drastically reduced. In one embodiment of the present invention, in order to solve this problem, the first receiving space (S1) and the second receiving space (S2) are communicated through the first inlet (112c), and the first receiving space (S1) and the third receiving space (S3) are communicated through the second inlet (112d). Furthermore, the upper surface (112-9) of the second wall (112) and the lower surface of the cover portion (113) are made in close contact to isolate the first accommodation space (S1) and the second accommodation space (S2), but a first inlet portion (112c) is formed in a part of the upper surface (112-9) of the second wall (112), so that this first inlet portion (112c) is not in close contact with the lower surface of the cover portion (113), and the first accommodation space (S1) and the third accommodation space (S3) are isolated, but a second inlet portion (112d) is formed, so that this second inlet portion (112d) is not in close contact with the lower surface of the cover portion (113), so that a medium and air can move between the first accommodation space (S1) and the second accommodation space (S2).

Meanwhile, in Fig. 8, the first passage (113-1) and the second passage (113-2) are shown with their positions changed to help understand the first passage (113-1) and the second passage (113-2), and the cross-sectional view of the cover part (113) of Fig. 5 connected to the second wall (112) is not shown as is.

Although the present invention has been described with reference to the embodiments illustrated in the accompanying drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Accordingly, the true scope of protection of the present invention should be determined only by the appended claims.
