Description

Skin care device equipped with a wire power transmission structure

[0001] The present invention relates to a skin care device having a wire power transmission structure, and more specifically, to a skin care device having a wire power transmission structure that mounts a driving force generating unit for a handpiece to a control body and transmits driving force to a handpiece through a wire.

[0002] As interest in skin care has been increasing day by day, various skin care devices are being developed.

[0003] Devices for skin care are proposed in various structures, such as skin treatment devices using ultrasound, skin treatment devices using laser, skin treatment devices using RF energy, skin cleansing devices for face lifting or skin tightening treatments, and cooling fat dissolving treatment devices.

[0004] A device for skin care using ultrasound uses a handpiece for generating ultrasound to generate heat from high-intensity focused ultrasound waves in skin tissue at a certain depth from the skin surface, thereby inducing degeneration and regeneration of skin tissue, thereby producing skin beauty effects such as wrinkle improvement or cosmetic surgery.

[0005] In addition, a skin treatment device using a laser uses a handpiece for generating a laser to irradiate the skin with a laser of a certain size as a point, and only applies heat with the laser to the target area to damage the skin tissue, treating the patient's skin. It is used for various purposes such as preventing hair loss, promoting hair growth, peeling, skin regeneration, whitening, removing wrinkles or spots, and removing freckles.

[0006] In addition, a skin treatment device using RF energy is performed by applying electric power to the RF electrode while the RF electrode is in close contact with the skin using a handpiece equipped with an RF electrode to deliver RF energy to the patient's skin, and is used in various ways, such as skin remodeling / resurfacing through contraction or wound healing response of collagen in the lower dermis, wrinkle removal, and treatment of sebaceous glands, hair follicles, fatty tissue, and spider veins.

[0007] In addition, the skin cleansing device treats the patient's skin by discharging a cleansing solution to the skin surface through a skin cleansing handpiece to penetrate functional cosmetic ingredients into the skin and polishing the skin surface.

[0008] Additionally, a cryolipolysis device for cryolipolysis treatment is used in which a cooling cup is mounted on one handpiece to cool the treatment area of ​​the patient.

[0009] Cooling cups are divided into suction-type, which cools the patient's skin by suction, and non-suction-type, which does not, and their performance varies depending on the type and quantity of thermoelectric elements attached to the cooling cup.

[0010] The practitioner can increase the effectiveness of cryolipolysis by selecting the most suitable cooling cup among various types of cooling cups depending on the patient's obesity status or the treatment area.

[0011] Meanwhile, the skin care device includes a skin treatment handpiece that performs a skin treatment by contacting the skin of a subject and stimulating the skin, and a control body that is connected to the skin treatment handpiece by a cable and controls the operation of the handpiece for generating ultrasound.

[0012] A handpiece for skin treatment is provided with a skin stimulation generating unit that stimulates the skin, and a driving force generating unit for moving or rotating the skin stimulation generating unit.

[0013] Additionally, the handpiece for skin treatment may be equipped with a driving force generating unit for generating vibrations for skin massage, etc.

[0014] For example, a handpiece for generating ultrasound or a handpiece for generating laser is equipped with a driving motor that moves the ultrasound or laser generating unit in a straight line or rotates it at a preset radius.

[0015] Additionally, the skin cleansing handpiece is equipped with a driving motor for rotating the polishing pad.

[0016] In addition, the skin cleansing handpiece, the handpiece equipped with an RF electrode, the cooling cup, and the skin cleansing handpiece are equipped with a vibration motor to generate vibrations for massaging the skin.

[0017] That is, conventional skin care devices have a driving force generating unit such as a driving motor or a vibration motor located within a skin treatment handpiece, and include a substrate having a driving circuit and a sensing circuit for controlling the operation of the driving force generating unit, a gear structure for transmitting the rotational force of the motor, etc., which has a problem in that the size and shape of the skin treatment handpiece are limited.

[0018] In addition, the handpiece for skin treatment is heavy because it includes a motor, a substrate, and a gear structure for transmitting the rotational power of the motor, and there is a problem that the vibration generated when the motor is operated during treatment puts a strain on the operator's wrist and causes discomfort during the treatment movement.

[0019] The purpose of the present invention is to provide a skin care device having a wire power transmission structure that can simplify the structure of the handpiece and reduce its weight by mounting a driving force generating unit for a handpiece on a control body and transmitting the driving force to the handpiece through a wire.

[0057] In addition, when describing the present invention below, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

[0058] FIG. 1 is a drawing illustrating one embodiment of a skin care device having a wire power transmission structure according to the present invention, and FIG. 2 is a cross-sectional view illustrating one embodiment of a skin care device having a wire power transmission structure according to the present invention.

[0059] Referring to FIGS. 1 and 2, one embodiment of a skin care device having a wire power transmission structure according to the present invention is described in detail below.

[0060] One embodiment of a skin care device having a wire power transmission structure according to the present invention includes a skin treatment handpiece (100) that contacts the skin to stimulate the skin, and a control body (200) that is connected to the skin treatment handpiece (100) by a connection cable body (210) to control the operation of the skin treatment handpiece (100).

[0061] A handpiece (100) for skin treatment is provided with a skin stimulation generating unit (400) that stimulates the skin, and the skin stimulation generating unit (400) is, for example, one of an ultrasonic generating unit (410) that irradiates ultrasonic waves to the skin, a laser generating unit that irradiates laser to the skin, an RF electrode unit that contacts the skin and transmits RF energy to the skin, a cup unit that contacts the skin and alternately generates negative pressure and positive pressure on the skin, and a skin massage unit that rotates or vibrates while in contact with the skin.

[0062] The skin stimulation generating unit (400) is a known skin care treatment device that stimulates the skin and performs skin care treatment, and a detailed description thereof is omitted.

[0063] That is, the skin care device having a wire power transmission structure according to the present invention is, for example, any one of known skin care treatment devices, such as a skin ultrasound generator including a handpiece for ultrasonic treatment, a skin laser generator including a handpiece for laser treatment, a skin RF energy generator including a handpiece for RF treatment, a skin negative pressure generator including a handpiece for negative pressure treatment, and a skin beauty device including a handpiece for skin massage.

[0064] A handpiece (100) for skin treatment includes a cartridge housing part (110) having a skin stimulation generating part (400) that comes into contact with the skin and provides stimulation, and a handpiece main body casing part (120) to which the cartridge housing part (110) is detachably coupled.

[0065] The cartridge housing part (110) is a consumable part that cannot be used for skin treatment and is replaced when the skin stimulation generating part (400) is used for a preset treatment time or preset number of treatments, and is detachably connected to the handpiece main body casing part (120).

[0066] As an example, the cartridge housing part (110) is coupled by sliding to the tip of the handpiece body casing part (120) and is locked by the cartridge locking part (120a) at the final coupling position to complete the coupling.

[0067] The cartridge locking part (120a) is a button-type locking part located on both sides of the handpiece main body casing part (120). A wedge part is located to hook and support the cartridge housing part (110) on an elastically supported button part, and a detailed description thereof is omitted.

[0068] The control body (200) is connected to the skin treatment handpiece (100) by a connecting cable body (210) including a plurality of wires or a circulating hose, etc., to control the operation of the skin stimulation generating unit (400) in the skin treatment handpiece (100) and to circulate a liquid such as cooling water or a medium in the cartridge housing unit (110).

[0069] It is to be noted that the control body (200) can be implemented in various ways by modifying the control structure applied according to the type of skin stimulation generating unit (400) in a skin care device such as a skin laser generating device, a skin RF energy generating device, a negative pressure generating device, and a skin beauty device.

[0070] The skin stimulation generating unit (400) is movably positioned within the interior of the skin treatment handpiece (100), i.e., within the cartridge housing unit (110), and one embodiment of the skin care device having a wire power transmission structure according to the present invention further includes a driving force generating unit (300) mounted within the control body (200) and generating a driving force to move the skin stimulation generating unit (400).

[0071] The driving force of the driving force generating unit (300) is transmitted to the skin stimulation generating unit (400) through a freely bendable string-shaped operating wire unit (500).

[0072] The driving force generating unit (300) is a wire linear moving unit that pulls or pushes the operating wire unit (500), and the operating wire unit (500) has a material or structure that has rigidity that can push and move the skin stimulation generating unit (400).

[0073] The operating wire section (500) is, for example, a wire made of a metal material such as steel wire.

[0074] The operating wire section (500) is directly connected to the skin stimulation generating section (400) at the end, and can move the skin stimulation generating section (400) from a preset basic position to a preset movement limit position by pushing it, and can return the skin stimulation generating section (400) from the preset movement limit position to the preset basic position by pulling it.

[0075] Alternatively, the operating wire section (500) is not shown, but is positioned between a plurality of metal ring members and connects the metal ring members, and includes a ring connecting member made of a flexible material such as cloth or synthetic resin, so as to secure rigidity for transmitting the linear movement of the driving force generating section (300) to the metal ring members, and can be freely bent through each joint between the metal ring members by the ring connecting member.

[0076] In addition, the operating wire section (500) can be modified in various ways and implemented using a known wire or hose structure that has the rigidity to directly transfer the force generated by the driving force generating section (300) to the skin stimulation generating section (400) to move the skin stimulation generating section (400) in a straight line by pulling or pushing the skin stimulation generating section (400).

[0077] The skin care device having a wire power transmission structure according to the present invention further includes a movement guide member (600) that is arranged lengthwise in the linear movement direction of the skin stimulation generating unit (400) within the skin treatment handpiece (100) and to which the skin stimulation generating unit (400) is movably coupled to guide the linear movement of the skin stimulation generating unit (400).

[0078] As an example, the moving guide member (600) is positioned on the upper side of the skin stimulation generating unit (400) and is connected to the moving body unit (420) connected to the operating wire unit (500) so as to be movably coupled to guide the linear movement of the skin stimulation generating unit (400).

[0079] The moving guide member (600) is formed in the shape of a rod or bar that penetrates the skin stimulation generating unit (400), i.e., the moving body unit (420), and guides the linear movement of the skin stimulation generating unit (400).

[0080] The operating wire section (500) is connected at one end to the driving force generating section (300) and at the other end to the skin stimulation generating section (400), and is pulled or pushed by the driving force generating section (300) to move forward and backward in a straight line, and transmits the driving force that moves forward and backward to the skin stimulation generating section (400) to move the skin stimulation generating section (400) back and forth in a straight line.

[0081] The operating wire section (500) supplies electric power to the skin stimulation generating section (400) and controls the operation of the skin stimulation generating section (400) by passing through the inside of the connecting cable body (210) to connect the skin stimulation generating section (400) and the driving force generating section (300), and is moved in a straight line by the operation of the driving force generating section (300) to move the skin stimulation generating section (400) in a straight line, as an example.

[0082] The driving force generating unit (300) is connected to the main control unit (220) located within the control body (200) to control its operation, and the main control unit (220) is electrically connected to the skin stimulation generating unit (400) of the skin treatment handpiece (100) through the connecting cable body (210) to control the operation of the skin stimulation generating unit (400).

[0083] The driving force generating unit (300) includes a rotational motor unit (310) that generates rotational force and a linear movement conversion unit (320) that converts the rotational force of the rotational motor unit (310) into linear movement to push or pull the operating wire unit (500).

[0084] As an example, the linear movement conversion unit (320) includes a rotating plate member (321) that is connected to the operating wire member (500) at a distance from the center of rotation and rotates on the rotating motor member (310).

[0085] The operating wire section (500) is positioned apart from the center of rotation of the rotary plate member (321) and moves in a circle with a preset radius by the rotation of the rotary plate member (321) and is pulled or pushed to move back and forth in a straight line.

[0086] The linear movement range of the operating wire part (500) is the same as the rotation diameter of the operating wire part (500), and can be set by adjusting the distance between the rotation center of the rotating plate member (321) and the point where the end of the operating wire part (500) is connected.

[0087] In addition, although not shown, the linear motion conversion unit (320) may be a rack-and-pinion structure including a pinion gear mounted on the motor shaft of the rotary motor unit (310) and a rack gear unit to which an operating wire unit (500) is connected, and in addition, it may be implemented in various modified forms as a known linear motion conversion structure that converts rotational power into linear motion.

[0088] The operating wire section (500) moves back and forth in a straight line as the rotating plate member (321) rotates by the operation of the rotating motor section, and the skin stimulation generating section (400) is directly connected to the operating wire section (500) and moves back and forth in a straight line together with the linear movement of the operating wire section (500).

[0089] The skin stimulation generating unit (400) includes a moving body unit (420) to which an operating wire unit (500) is connected and through which a moving guide member (600) passes and is positioned.

[0090] At the end side of the operating wire section (500), a driving force transmission coupling section (510) is provided that is detachably connected to the moving body section (420), i.e., the skin stimulation generating section (400).

[0091] As an example, the driving force transmission coupling part (510) includes a magnetic part that is attached to the skin stimulation generating part (400) by magnetic force.

[0092] The driving force transmission coupling part (510) includes a magnet part provided on one side of the skin stimulation generating part (400) and the driving force transmission coupling part (510), and a magnetic body provided on the other side of the skin stimulation generating part (400) and the driving force transmission coupling part (510) and magnetically attached to the magnet part.

[0093] In addition, the magnetic body may be another magnet facing the magnet with a different polarity from the magnet part, or may be implemented in various ways by being a known material that can be magnetically attached to the magnet, so a more detailed description is omitted.

[0094] The driving force transmission coupling part (510) is detachably coupled to the skin stimulation generating part (400) by the magnetic force of the magnet part, so that when the cartridge housing part (110) is separated from the handpiece main body casing part (120), the skin stimulation generating part (400) is separated from the operating wire part (500).

[0095] And, when the new cartridge housing part (110) is coupled to the handpiece body casing part (120), the driving force transmission coupling part (510) is attached to the skin stimulation generating part (400) by the magnetic force of the magnet part, so that the skin stimulation generating part (400) can be moved by the operation of the operating wire part (500).

[0096] That is, the cartridge housing part (110) is a spare part that is replaced when the life of the skin stimulation generating part (400) ends, and is separated from the handpiece main body casing part (120) and replaced. At this time, the operating wire part (500) can be separated from or combined with the skin stimulation generating part (400) through the driving force transmission coupling part.

[0097] The driving force transmission coupling part (510) can be simply and detachably coupled to the skin stimulation generating part (400) through the magnetic force of the magnet part by simply moving the operating wire part (500) when replacing the cartridge housing part (110).

[0098] The driving force transmission coupling part (510) can be implemented in various modifications using a known coupling structure that can be simply coupled by movement of the operating wire part (500) in addition to the magnet part.

[0099] In addition, the handpiece (100) for skin treatment further includes a coupling movement guide (700) that connects one side of a skin stimulation generating unit (400) and an inner surface of a cartridge housing unit (110), has a length-adjustable structure, and has a coupling unit (510) for transmitting driving force inserted therein to guide the movement of the coupling unit (510) for transmitting driving force.

[0100] The coupling part (510) for transmitting driving force is positioned so as to protrude from the coupling surface where the cartridge housing part (110) is coupled to the handpiece body casing part (120), and when the cartridge housing part (110) is coupled to the handpiece body casing part (120), it is inserted into and positioned within the coupling movement guide part (700).

[0101] The coupling movement guide (700) has a movement passage that is exposed through one side of the cartridge housing (110) so that a coupling part (510) for transmitting driving force can be inserted, and when the cartridge housing (110) is coupled to the handpiece main body casing (120), the coupling part (510) for transmitting driving force is inserted into the movement passage.

[0102] The combined movement guide (700) has a structure that can be adjusted in length, so that the space within the movement path is maintained while the length is shortened or lengthened when the skin stimulation generating unit (400) moves, and the skin stimulation generating unit (400) can move smoothly.

[0103] The connecting cable body (210) is fixed on the joint surface of the handpiece body casing part (120) to guide the linear movement of the operating wire part (500), thereby minimizing the loss of driving power of the operating wire part (500) due to the operation of the driving power generating part (300).

[0104] In addition, the coupling part (510) for transmitting driving force is positioned so as to protrude on the coupling surface of the handpiece body casing part (120), so that when the cartridge housing part (110) is coupled to the handpiece body casing part (120), the coupling part (510) for transmitting driving force is inserted into the moving passage.

[0105] When replacing the cartridge housing (110), the driving force transmission coupling part (510) is inserted into the communication passage and positioned apart from the skin stimulation generating part (400), and can be moved forward toward the skin stimulation generating part (400) by the operation of the driving force generating part (300) and magnetically attached to one side of the skin stimulation generating part (400) and coupled.

[0106] In addition, the operating wire section (500) moves the skin stimulation generating section (400) smoothly forward and backward while the end side fixed to the driving force transmitting coupling section (510) moves linearly within the coupling movement guide section (700).

[0107] As an example, the combined movement guide (700) is a Javara portion (710) having one end fixed to a skin stimulation generating portion (400) and the other end fixed to one side of a cartridge housing portion (110) and including a plurality of folds that can be folded and unfolded.

[0108] The Javara portion (710) is opened to one side of the cartridge housing portion (110) and forms a passage for the driving force transmission coupling portion (510) to move, and guides the movement of the driving force transmission coupling portion (510) inside.

[0109] Accordingly, the driving force transmission coupling part (510) is inserted into the inside of the Java part (710) while the cartridge housing part (110) is coupled to the coupling surface of the handpiece body casing part (120) and is spaced apart from the skin stimulation generating part (400), and is pushed by the operating wire part (500) to smoothly move toward the skin stimulation generating part (400) so that it can be magnetically stably attached to one side of the skin stimulation generating part (400).

[0110]

[0111] Meanwhile, the skin care device having a wire power transmission structure according to the present invention is a skin ultrasound generator that generates high intensity focused ultrasound (HIFU) with the ultrasound generator (410) including the skin stimulation generator (400) as an example, and an embodiment is described in more detail below. In addition, it is to be noted that the device may be any one of other skin care devices, that is, a skin laser generator, a skin RF energy generator, a sound pressure generator, and a skin beauty device.

[0112] The cartridge housing part (110) is provided with a window part (110a) on the lower surface through which ultrasonic waves generated from the ultrasonic generator (410) pass, and which can move internally.

[0113] The window section (110a) is manufactured from a transparent or translucent film material, and a detailed description thereof is omitted as it is a known structure manufactured from a film material through which ultrasonic waves can pass.

[0114] The ultrasonic generator (410) is movably positioned in the cartridge housing (110) and is an ultrasonic transducer that generates high intensity focused ultrasound (HIFU). The ultrasonic transducer generates heat by irradiating the skin muscle layer with high intensity focused ultrasound (HIFU), thereby inducing degeneration and regeneration of skin tissue, thereby improving skin wrinkles and increasing skin elasticity.

[0115] The ultrasonic generator (410) is connected to the upper side moving body (420) and moves linearly back and forth within the cartridge housing (110) together with the linear movement of the moving body (420).

[0116] The window section (110a) is formed with a length longer than the movement range of the ultrasonic generator (410), so that ultrasonic waves generated from the ultrasonic generator (410) moving in a straight line back and forth can be stably transmitted.

[0117] A liquid medium for transmitting ultrasonic waves is filled inside the cartridge housing (110), and a java part (710) connecting one side of the moving body part (420) and one side of the cartridge housing part (110), i.e., a coupling movement guide part (700), is positioned so that an operating wire part (500) is coupled to the moving body part (420) inside to form a movement passage through which it can move smoothly.

[0118] The Javara portion (710) forms a sealed space inside the moving passage that is blocked from the liquid medium, thereby blocking the operating wire portion (500) located inside from the medium, so that it can smoothly move in a straight line to the driving force generating portion (300), and when the cartridge housing portion (110) is separated from the handpiece body casing portion (120), the liquid medium is prevented from leaking to the outside at the shaft-joining portion of the screw member (521a), that is, when the cartridge housing portion (110) is separated from the handpiece body casing portion (120) at the shaft adapter portion (530).

[0119]

[0120] Meanwhile, FIG. 3 is a cross-sectional view showing another embodiment of a skin care device having a wire power transmission structure according to the present invention, and referring to FIG. 3, the driving force generating unit (300) may include a linear actuator (330) to which an operating wire unit (500) is connected and which pulls or pushes the operating wire unit (500) to move it in a straight line.

[0121] The linear actuator (330) is, for example, a ball screw actuator or a hydraulic cylinder that moves in a straight line using a ball screw method, and may also be modified and implemented as a known actuator having a straight reciprocating movement structure.

[0122] The linear actuator (330) moves the wire connection part to which the operating wire part (500) is connected in a linear reciprocating manner to pull or push the operating wire part (500), thereby moving the skin stimulation generating part (400) connected to the operating wire part (500) in a linear reciprocating manner.

[0123]

[0124] FIGS. 4 and 5 are enlarged cross-sectional views illustrating an operation example of one embodiment of a skin care device having a wire power transmission structure according to the present invention. Referring to FIGS. 4 and 5, the operating wire portion (500) is connected to the moving body portion (420) by a driving force transmission coupling portion (510) inside the java portion (710), and is moved by being pulled or pushed by the driving force generating portion (300) to move the moving body portion (420) forward and backward.

[0125] And, the ultrasonic generator (410), i.e., the skin stimulation generator (400), moves back and forth together with the moving body (420) to irradiate ultrasonic waves to the skin.

[0126]

[0127] Meanwhile, FIG. 6 is an enlarged cross-sectional view showing an example of a connecting cable body in one embodiment of a skin care device having a wire power transmission structure according to the present invention, and referring to FIG. 6, a wire movement guide tube part (213) is further included, which is fixed to the inside of the connecting cable body (210) and through which an operating wire part (500) passes to guide the movement of the operating wire part (500).

[0128] The connecting cable body (210) is electrically connected to the skin stimulation generating unit (400) located in the handpiece main body casing unit (120) to supply electric power to the stimulation generating unit, and an operating control cable (212) for controlling the operation of the skin stimulation generating unit (400) and an operating wire unit (500) that moves in a straight line by the driving force generating unit (300) pass through the inside.

[0129] The wire movement guide tube section (213) is fixedly positioned inside the connecting cable body (210) and supports the position of the operating wire section (500) passing through the inside, thereby minimizing the change in tension of the operating wire section (500) when the connecting cable body (210) is bent, thereby enabling smooth movement of the operating wire section (500) and stable transmission of power through the operating wire section (500).

[0130] The operating wire section (500) passes through the inside of the wire movement guide tube section (213) whose position is fixed within the connecting cable body (210) and is connected to the skin stimulation generating section (400), thereby allowing the skin stimulation generating section (400) to be stably moved forward and backward.

[0131] The connecting cable body (210) includes an outer covering (211) that surrounds an operating control cable (212) passing through the inside and a wire movement guide tube section (213), and may further include an elastic filler (214) that is filled inside the outer covering (211) and supports the positions of the operating control cable (212) and the wire movement guide tube section (213).

[0132] As an example, the filler (214) is a synthetic resin foam material such as polyethylene foam, and the filler (214) stably supports the position of the wire movement guide tube part (213) that guides the movement of the operating wire part (500), so that when the connecting cable body (210) is bent, the movement of the operating wire part (500) can be made smoother and power transmission through the operating wire part (500) can be made more stable.

[0133]

[0134] The present invention can greatly improve the convenience and satisfaction of the operator during the procedure by reducing the weight of the handpiece (100) for skin treatment by mounting a driving force generating unit (300) for moving an operating body in the handpiece to the control body (200) and transmitting the driving force through a wire.

[0135] In addition, the present invention can improve the treatment environment by not generating noise or vibration due to operation within the handpiece (100) for skin treatment, thereby greatly enhancing the satisfaction of the practitioner and the patient during the treatment.

[0136] In addition, the present invention simplifies the structure of a handpiece (100) for skin treatment, thereby enabling the design of the handpiece (100) for skin treatment without limitations on the size and shape, thereby greatly improving the degree of freedom in handpiece design.
