Description

Cartridge for generating ultrasonic waves that detects contact status with a light sensor and handpiece for generating ultrasonic waves equipped therewith

[0001] The present invention relates to an ultrasonic handpiece for generating ultrasound that detects a contact state with a light sensor and an ultrasonic generator having the same, and to an ultrasonic handpiece for generating ultrasound that detects a contact state with a light sensor that detects the amount of light entering through a window that comes into contact with the skin and confirms the contact state between the window and the skin, and an ultrasonic generator having the same.

[0002] Just as when sunlight is focused on one spot with a convex lens, heat is generated at the focal point, when high-intensity ultrasonic energy is focused on one spot, high heat of about 65 to 100℃ is generated at the focal point.

[0003] The device that uses the heat generated by focused ultrasound to burn and remove (coagulative necrosis) specific subcutaneous tissues such as tumors within the skin is a high-intensity focused ultrasound surgical device, and the device that uses the heat generated by focused ultrasound to induce degeneration and regeneration of skin tissues to produce skin beauty or cosmetic effects such as wrinkle improvement is a miniaturized high-intensity focused ultrasound device known as "Ulthera."

[0004] This high-intensity focused ultrasound device includes a main body that supplies power for generating ultrasound and generates a control signal according to the operator's operation, and a handpiece that is connected to the main body via a connection cable and is held by the operator's hand and comes into contact with the skin to generate ultrasound.

[0005] Meanwhile, a handpiece for generating ultrasound using high-intensity focused ultrasound is configured to include an ultrasound generating cartridge including an ultrasound generating unit and a main body casing in which the ultrasound generating cartridge is detachably mounted and connected to a control main body.

[0006] Ultrasonic cartridges are replaced periodically because the ultrasonic generator has a limited number of uses.

[0007] The ultrasonic cartridge is filled with a liquid medium, an ultrasonic generator is positioned within the liquid medium, and a window for transmitting ultrasonic waves is provided at the bottom.

[0008] The handpiece for generating ultrasound using high-intensity focused ultrasound performs treatment by generating high-intensity focused ultrasound while moving the ultrasound generating unit with a mobile device within the ultrasound generating cartridge.

[0009] That is, the practitioner operates the ultrasound generator while placing the window of the ultrasound generating cartridge in contact with the patient's skin and simultaneously moves the ultrasound generator back and forth with a moving device to perform the ultrasound treatment.

[0010] Meanwhile, during a procedure using high-intensity focused ultrasound, the window of the handpiece for generating ultrasound must be in close contact with the patient's skin.

[0011] If part of the window of the handpiece for generating ultrasound detaches from the patient's skin during the procedure, there is a risk that the patient's skin tissue may be damaged by heat or burns may occur due to a rapid increase in temperature within the skin tissue.

[0012] As a result, the practitioner must frequently check whether the window of the handpiece for generating ultrasound is in close contact with the skin during the procedure, which results in a long treatment time and significant psychological fatigue for the practitioner during the treatment.

[0013]

[0014] *In addition, because the practitioner applies a lot of force to press the handpiece for ultrasound generation to seal the window of the handpiece for ultrasound generation during the procedure, the patient feels uncomfortable, and it can cause joint disease in the practitioner's wrist, etc., and there was a problem that long-term stable treatment was impossible.

[0015] Conventional handpieces for generating ultrasound have multiple contact sensors on the lower surface of the cartridge for generating ultrasound to confirm that the window is in close contact with the skin, and the contact sensors detect contact by a change in electrostatic capacity when the window is in contact with the skin.

[0016] That is, since the conventional handpiece for generating ultrasound uses a contact sensor that detects direct contact with the skin, a plurality of contact sensors are provided on the lower surface of the cartridge for generating ultrasound, and when a plurality of contact sensors are in contact with the skin at the same time, it is confirmed that the window is in close contact with the skin.

[0017] Conventional handpieces for generating ultrasound have the problem of high manufacturing costs because they use multiple contact sensors to confirm that the window part is in close contact with the skin.

[0018] In addition, conventional handpieces for generating ultrasound have a problem in that it is difficult to accurately confirm that the window is in contact with the skin even if a malfunction occurs in one contact sensor, and it is difficult to confirm that a malfunction has occurred in the contact sensor, making it impossible to reliably confirm that the window is in contact with the skin.

[0019] Meanwhile, conventional handpieces for generating ultrasound have no means of confirming the treatment range due to the movement of the ultrasound generator, which can lead to the risk of the practitioner performing the same procedure repeatedly on the patient's skin at the same treatment location, and there is a problem in that the treatment location cannot be accurately confirmed, resulting in reduced efficiency during the procedure.

[0020] A prior patent related to the present invention is Korean Patent Registration No. 1307551, “Handpiece of ultrasonic device” (registered on September 5, 2013).

[0021] The purpose of the present invention is to provide an ultrasonic generating cartridge that detects the contact state by using an illuminance sensor to accurately check the contact state between the window and the skin by detecting the amount of light entering through a window that comes into contact with the skin, and an ultrasonic generating handpiece equipped with the cartridge.

[0022] Another object of the present invention is to provide an ultrasonic generation handpiece that prevents overlapping treatments at the same treatment location by checking the treatment range of an ultrasonic generation cartridge with light.

[0023] In order to achieve the above-described object of the present invention, one embodiment of a cartridge for generating ultrasonic waves that detects a contact state with a light sensor is characterized by including a cartridge housing part having a window part that is filled with a liquid medium inside and has a lower surface through which ultrasonic waves pass and come into contact with the skin, an ultrasonic generation part located within the cartridge housing part and generating ultrasonic waves toward the window part, and an light sensor part located within the cartridge housing part and measuring the amount of light that enters the inside through the window part to confirm a state in which the window part is in close contact with the skin.

[0024] In the present invention, the ultrasonic generator may move in a linear reciprocating manner, and the illuminance sensor may include a first illuminance sensor positioned in front of the ultrasonic generator in the direction of movement of the ultrasonic generator and a second illuminance sensor positioned in the rear of the ultrasonic generator.

[0025] In order to achieve the purpose of the present invention, one embodiment of an ultrasonic generating cartridge that detects a contact state with a light sensor may further include a sensor cover that moves back and forth in a straight line within a preset range together with the ultrasonic generating unit, covers a first light sensor at a predetermined position on the front side of the ultrasonic generating unit, and covers a second light sensor at a predetermined position on the rear side of the ultrasonic generating unit.

[0026]

[0027] In order to achieve the above-described object of the present invention, one embodiment of an ultrasonic generating handpiece according to the present invention is characterized by including an ultrasonic generating cartridge having an ultrasonic generating unit that irradiates ultrasonic waves to the skin through a window unit in a cartridge housing unit that is in contact with the skin, a handpiece main body casing unit in which the ultrasonic generating cartridge is detachably mounted and connected to a control main body, and a treatment range indicating lamp unit that irradiates light to the side of the ultrasonic generating cartridge to indicate the treatment range of the ultrasonic generating unit.

[0028] In the present invention, the ultrasonic generator moves back and forth in a straight line in a preset movement range, and the lamp unit for indicating the treatment range irradiates light downward from the upper side of the ultrasonic generator cartridge while the window unit is in contact with the patient's skin, thereby irradiating light corresponding to the treatment range on one side of the ultrasonic generator cartridge, and irradiating light on the patient's skin to form a line beam having a length corresponding to the treatment range.

[0029] In the present invention, the ultrasonic generator moves back and forth in a straight line in a preset movement range, and a light guide unit may be provided on the side of the cartridge housing unit to guide the light of the lamp unit for indicating the treatment range to indicate the treatment range of the ultrasonic generator on the patient's skin.

[0030] In the present invention, the light guide unit can form a line beam in the shape of a line having a length corresponding to the treatment range of the ultrasound generator unit on the patient's skin.

[0031] In the present invention, the light guide part may include a first light guide side wall part and a second light guide side wall part that are spaced apart from the direction in which light is irradiated to form an optical path through which light travels.

[0032] In the present invention, the space between the first light-guiding side wall portion and the second light-guiding side wall portion has an open shape toward the upper side and the lower side, and the lamp portion for indicating the treatment range can be positioned spaced apart from the upper side opened between the first light-guiding side wall portion and the second light-guiding side wall portion.

[0033] In the present invention, a first light-guiding protrusion and a second light-guiding protrusion may be positioned protrudingly on the upper side of the first light-guiding side wall portion and the second light-guiding side wall portion, respectively, to prevent the light generated from the lamp portion for indicating the treatment range from spreading.

[0034] In the present invention, the lamp unit for indicating the treatment range can generate light of different colors depending on the operating status of the ultrasonic generating cartridge.

[0035] In the present invention, the ultrasonic generating cartridge may include an embodiment of an ultrasonic generating cartridge that detects a contact state using a light sensor according to the present invention.

[0036] In the present invention, the lamp unit for indicating the treatment range generates light of different colors depending on the operating state of the ultrasonic generating cartridge, and the operating state of the ultrasonic generating cartridge may include a standby state in which the window unit is in contact with the skin and it is not confirmed that the window unit is completely in contact with the skin, a treatment preparation state in which the light sensor unit confirms that the window unit is in contact with the skin, a treatment-during state in which the treatment is performed while the ultrasonic generating unit is moved, and an operating error state of the ultrasonic generating cartridge.

[0037] In the present invention, the lamp unit for indicating the treatment range irradiates light onto the patient's skin, and when the window unit is separated from the skin, a portion of the light can be introduced into the cartridge housing unit through the window unit to be detected by the light sensor unit.

[0038] In the present invention, the cartridge housing portion may be provided with a guide slope on the lower side that is inclined toward the window portion and guides light emitted from the lamp portion for indicating the treatment range to the window portion.

[0039] The present invention detects the amount of light entering through a window in contact with the skin using a light sensor, thereby accurately confirming the state of contact between the window and the skin, thereby preventing accidents in which skin tissue is damaged or burns occur due to separation between the window and the skin during the procedure, and has the effect of greatly improving safety during the procedure.

[0040] The present invention prevents the patient's skin from being injured, such as burns, by confirming the treatment location and treatment range and preventing the treatment from being repeated at the same treatment location, thereby significantly improving the safety of the treatment.

[0066] 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.

[0067] FIG. 1 is a cross-sectional view illustrating one embodiment of an ultrasonic generating cartridge for detecting a contact state with a light sensor according to the present invention, and with reference to FIG. 1, one embodiment of an ultrasonic generating cartridge for detecting a contact state with a light sensor according to the present invention will be described in detail below.

[0068]

[0069] One embodiment of a cartridge for generating ultrasonic waves that detects a contact state using a light sensor according to the present invention includes a cartridge housing portion (110) filled with a liquid medium therein.

[0070] The cartridge housing portion (110) is provided with a window portion (110a) through which ultrasonic waves generated from an ultrasonic generator (120) located inside the lower surface pass.

[0071] 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.

[0072] Inside the cartridge housing (110), an ultrasonic generator (120) that generates ultrasonic waves and irradiates them onto the skin of the subject of treatment is movably positioned.

[0073] The ultrasonic generator (120) is movably positioned in the cartridge housing (110) and includes, for example, a known ultrasonic transducer that generates ultrasonic waves.

[0074] More specifically, the ultrasonic generator (120) is an example that includes an ultrasonic transducer that generates high intensity focused ultrasound (HIFU).

[0075] High Intensity Focused Ultrasound (HIFU) generates heat by irradiating the skin muscle layer, which induces degeneration and regeneration of skin tissue, thereby improving wrinkles and increasing skin elasticity.

[0076] As an example, the ultrasonic generator (120) moves back and forth in a straight line within the cartridge housing (110), and the window (110a) is formed to have a length longer than the movement range of the ultrasonic generator (120) so that the ultrasonic waves generated from the ultrasonic generator (120) moving back and forth in a straight line can be stably transmitted.

[0077] Inside the cartridge housing (110), an actuator (not shown) that moves the ultrasonic generator (120) in a straight line and an actuator connection (140) that connects the ultrasonic generator (120) and transmits the driving force of the actuator (not shown) to the ultrasonic generator (120) are located.

[0078] An actuator (not shown) is provided in an ultrasonic generating handpiece to which an ultrasonic generating cartridge that detects a contact state with a light sensor according to the present invention is detachably coupled.

[0079] When the ultrasonic generating cartridge that detects the contact state with the light sensor according to the present invention is coupled to the ultrasonic generating handpiece, the ultrasonic generating unit (120) is connected to an actuator (not shown) through an actuator connecting unit (140) and receives driving force when the actuator is operated, thereby moving back and forth in a straight line within a preset movement range.

[0080] The actuator connection part (140) is located on the upper side of the ultrasonic generator (120), and includes a slider (141) that is connected to the actuator (not shown) and moves in a straight line by the operation of the actuator (not shown), a movement guide pin member (142) that is located through the slider (141) and guides the slider (141) to move in the longitudinal direction, a java member (143) that is located on each side of the slider (141) and folds and unfolds by the movement of the slider (141) to form a sealed space inside, and a power transmission part (144) that transmits the driving force of the actuator (not shown) to the slider (141).

[0081] The Java member (143) forms a sealed space inside, and an actuator (not shown) can be inserted inside through the sealed space and connected to the slider (141).

[0082] The Java member (143) blocks the liquid medium filled in the cartridge housing (110) from the internal space, while allowing the slider (141) to move smoothly along the movement guide pin member (142).

[0083] When the slider (141) moves, one of the two Java members (143) unfolds and the other folds, so that the slider (141) can move back and forth in a straight line along the movement guide pin member (142).

[0084] The power transmission unit (144) is, for example, a magnet or magnetic body that can be magnetically attached to an actuator (not shown).

[0085] The power transmission unit (144) has a rod insertion portion into which a rod can be inserted, and an actuator (not shown) has a rod inserted into the rod insertion portion and attached to the power transmission unit (144) by magnetic force.

[0086] That is, the slider (141) is magnetically connected to the actuator through the actuator connection part (140), and by the operation of the actuator, the slider (141) moves linearly along the movement guide pin member (142), and the ultrasonic generator (120) moves linearly back and forth together, enabling ultrasonic waves to be irradiated to the skin.

[0087]

[0088] Meanwhile, a light sensor unit (160) that measures the amount of light entering the interior through the window unit (110a) is located inside the cartridge housing unit (110).

[0089] The light sensor unit (160) detects the amount of light entering the interior through the window unit (110a) and can confirm that the window unit (110a) is in close contact with the skin.

[0090] That is, when the window part (110a) is completely in contact with the skin, light is not detected by the light sensor part (160), so when light is not detected by the light sensor part (160), it can be confirmed that the window part (110a) is in contact with the skin.

[0091] The illuminance sensor unit (160) includes a first illuminance sensor (161) positioned in front of the ultrasonic generator (120) in the direction of movement of the ultrasonic generator (120) and a second illuminance sensor (162) positioned in the rear of the ultrasonic generator (120).

[0092] Since the window part (110a) is formed to be the same length as or longer than the movement range of the ultrasonic generator (120), it is difficult to accurately measure the amount of light flowing in from both ends of the window part (110a) using only one light sensor.

[0093] The first roughness sensor (161) is mounted on the inner surface of the cartridge housing (110) so as to face the ultrasonic generator (120) on the front side of the ultrasonic generator (120) in the forward and backward linear movement direction of the ultrasonic generator (120), and the second roughness sensor (162) is mounted on the inner surface of the cartridge housing (110) so as to face the ultrasonic generator (120) on the rear side in the forward and backward linear movement direction of the ultrasonic generator (120).

[0094] The first illuminance sensor (161) measures the amount of light entering from the tip side in the longitudinal direction of the window part (110a), and the second illuminance sensor (162) measures the amount of light entering from the tip side in the longitudinal direction of the window part (110a).

[0095] The first light sensor (161) and the second light sensor (162) are positioned at each end of the length of the window portion (110a) to measure the amount of light entering the interior of the cartridge housing portion (110) through the window portion (110a), thereby accurately confirming the state in which the window portion (110a) is in full contact with the skin.

[0096] In addition, if only one light sensor is positioned within the cartridge housing (110), the light sensor may be covered depending on the position of the moving ultrasonic generator (120), making it difficult to accurately measure the amount of light entering through the window (110a).

[0097] The first sensor (161) and the second sensor (162) are spaced apart and positioned opposite each other within the cartridge housing (110).

[0098] When the ultrasonic generator (120) covers one of the first illuminance sensor (161) and the second illuminance sensor (162), the other illuminance sensor of the first illuminance sensor (161) and the second illuminance sensor (162) is exposed toward the window portion (110a), so that the amount of light entering through the window portion (110a) can be checked.

[0099] That is, regardless of the position of the ultrasonic generator (120), either the first illuminance sensor (161) or the second illuminance sensor (162) is not covered by the ultrasonic generator (120) and is exposed toward the window portion (110a), so that the amount of light entering the cartridge housing portion (110) through the window portion (110a) can be measured, and the state in which the window portion (110a) is in close contact with the skin can be confirmed.

[0100]

[0101] Meanwhile, FIGS. 2 and 3 are cross-sectional perspective views illustrating another embodiment of a cartridge for generating ultrasonic waves that detects a contact state with a light sensor according to the present invention. FIG. 2 illustrates an example in which the ultrasonic wave generating unit (120) is moved to the front side and positioned to cover the first light sensor (161) located inside the cartridge housing unit (110), and FIG. 3 illustrates an example in which the ultrasonic wave generating unit (120) is moved to the rear side and positioned to cover the second light sensor (162) located inside the cartridge housing unit (110).

[0102] The ultrasonic generator (120) is positioned to cover the first roughness sensor (161) at the maximum movement position on the front side when moving back and forth in a straight line, and is positioned to cover the second roughness sensor (162) at the maximum movement position on the rear side when moving back and forth in a straight line.

[0103] The first roughness sensor (161) and the second roughness sensor (162) are mounted on the upper surface inside the cartridge housing (110) to be spaced apart in the direction of movement of the ultrasonic generator (120), and the first roughness sensor (161) is positioned on the front side in the direction of movement of the ultrasonic generator (120), and the second roughness sensor (162) is positioned on the rear side in the direction of movement of the ultrasonic generator (120).

[0104] Another embodiment of a cartridge for generating ultrasonic waves for detecting a contact state with a light sensor according to the present invention further includes a sensor cover part (170) that moves back and forth in a straight line within a preset range together with an ultrasonic generator part (120), covers a first light sensor (161) at a maximum movement position on the front side, and covers a second light sensor (162) at a maximum movement position on the rear side.

[0105] For example, the sensor cover part (170) protrudes from at least one side of the upper part of the actuator connection part (140) to cover the first roughness sensor (161) or the second roughness sensor (162).

[0106] The sensor cover (170) is positioned to cover the first illuminance sensor (161) at the maximum movement position of the front-side ultrasonic generator (120) and to cover the second illuminance sensor (162) at the maximum movement position of the rear-side ultrasonic generator (120).

[0107] The sensor cover part (170) completely covers the first illuminance sensor (161) and the second illuminance sensor (162) to block light from entering the first illuminance sensor (161) and the second illuminance sensor (162) when the window part (110a) is completely open.

[0108] Another embodiment of the cartridge for generating ultrasonic waves that detects a contact state with a light sensor according to the present invention is to move the ultrasonic wave generating unit (120) to the maximum forward position so that the first light sensor (161) is completely covered by the sensor cover unit (170) and the window unit (110a) is opened to check whether the second light sensor (162) is operating normally.

[0109] In addition, another embodiment of the cartridge for generating ultrasonic waves that detects a contact state with a light sensor according to the present invention can check whether the second light sensor (162) is operating normally by opening the window (110a) in a state where the ultrasonic generation unit (120) is moved to the maximum forward position and the first light sensor (161) is completely covered by the sensor cover unit (170).

[0110] That is, another embodiment of the ultrasonic generating cartridge for detecting a contact state with a light sensor according to the present invention can simply check whether the second light sensor (162) and the first light sensor (161) are operating normally while the ultrasonic generating unit (120) moving back and forth in a straight line within a preset range is moved to the maximum forward movement position and the maximum rearward movement position, respectively.

[0111]

[0112] Meanwhile, FIG. 4 is an exploded perspective view illustrating one embodiment of a handpiece for generating ultrasonic waves according to the present invention, FIG. 5 is a side view illustrating one embodiment of a handpiece (200) for generating ultrasonic waves according to the present invention, and FIG. 6 is a cross-sectional view illustrating one embodiment of a handpiece (200) for generating ultrasonic waves according to the present invention.

[0113] Referring to FIGS. 4 to 6, one embodiment of an ultrasound generating handpiece (200) according to the present invention includes an ultrasound generating cartridge (100) having an ultrasound generating unit (120) positioned within a cartridge housing (110) having a window (110a) that comes into contact with the skin and irradiating ultrasound to the skin through the window (110a), a handpiece main body casing in which the ultrasound generating cartridge (100) is detachably mounted and connected to a control main body (300), and a treatment range indicating lamp unit (210) that irradiates light to the side of the ultrasound generating cartridge (100) to indicate the treatment range of the ultrasound generating unit (120).

[0114] The lamp unit (210) for indicating the treatment range is, for example, mounted on the casing unit of the handpiece body, and when the cartridge for generating ultrasonic waves (100) is combined, light is irradiated downward from one side of the cartridge for generating ultrasonic waves (100) to indicate the treatment range of the ultrasonic wave generating unit (120) on one side of the cartridge for generating ultrasonic waves (100).

[0115] The cartridge (100) for generating ultrasonic waves includes an embodiment of the cartridge (100) for generating ultrasonic waves that detects a contact state using the light sensor described above.

[0116] The cartridge (100) for generating ultrasonic waves is coupled by sliding to the tip of the handpiece body casing (200) and is locked by the cartridge locking part (200a) at the final coupling position to complete the coupling.

[0117] The cartridge locking part (200a) is a button-type locking part located on both sides of the handpiece main body casing part (200a). A wedge part is located to support the ultrasonic generating cartridge (100) by hanging it on the elastically supported button part, and a detailed description thereof is omitted as it utilizes a known configuration in which the lock is released when the button part is pressed.

[0118] The cartridge (100) for generating ultrasound can be detachably coupled to the handpiece main body casing part (200a) using the coupling structure of the cartridge applied to a known handpiece for generating ultrasound used in skin treatment.

[0119] The handpiece body casing (200) is connected to an ultrasonic generator (120), and an actuator (150) for moving the ultrasonic generator (120) is positioned inside, and is connected to a control body (300) that controls the operation of the ultrasonic generator (120) and the actuator (150).

[0120] The control body (300) can be implemented by various modifications of a known ultrasonic generator used for skin treatment by irradiating ultrasonic waves to the skin, as a known example, and a more detailed description thereof will be omitted.

[0121] An example of an actuator (150) is one that moves the ultrasonic generator (120) in a linear reciprocating manner, and an example of an ultrasonic generator (120) is one that is connected to the actuator (150) and moves in a linear reciprocating manner.

[0122] The actuator (150) includes a moving rod member (211) that is inserted into the interior of the Java member (143) and inserted into the rod insertion portion of the power transmission member (144) and is magnetically attached to the power transmission member (144).

[0123] The power transmission unit (144) has a rod insertion portion into which a moving rod member (211) can be inserted, and the moving rod member (211) is inserted into the rod insertion portion and attached to the power transmission unit (144) by magnetic force, thereby moving the slider (141) forward and backward by the driving force of the actuator (150).

[0124] The actuator (150) is not shown, but it has a structure in which a screw is rotated by the rotation of a rotary motor, and a moving bar member (211) is connected to a moving block that moves in a straight line by being screw-connected to the screw.

[0125] It is to be noted that the actuator (150) can be implemented in various modified forms as a known linear actuator.

[0126] As an example, the handpiece body casing part (200) is connected to the control body (300) by a connection cable (10).

[0127] The handpiece main body casing (200) and the ultrasonic generating cartridge (100) are each provided with a connection terminal for electrically connecting the ultrasonic generating unit (120) in the ultrasonic generating cartridge (100) to the control main body (300). When the ultrasonic generating cartridge (100) is coupled to the handpiece main body casing (200), the ultrasonic generating unit (120) is electrically connected to the control main body (300) through the connection terminal, so that the operation can be controlled through the control main body (300).

[0128] The configuration of the connection terminal can be implemented in various ways using the known technology of the known ultrasonic treatment device, so a more detailed description is omitted.

[0129] The ultrasonic generator (120) moves back and forth in a straight line inside the cartridge housing (110), and the range of the reciprocating movement is preset.

[0130] The lamp unit (210) for indicating the treatment range indicates the treatment range of the ultrasonic generator (120) within the preset movement range of the ultrasonic generator (120) and, as an example, notifies the practitioner by forming a line-shaped light on the patient's skin.

[0131] The lamp unit (210) for indicating the treatment range is an LED lamp as an example, and in addition, it can be modified and implemented in various ways using a known lamp that generates light, such as a laser lamp that can form a line beam on the skin using a laser.

[0132] The lamp unit (210) for indicating the treatment range is mounted on the inner surface of the side of the handpiece casing unit facing one side of the cartridge housing unit (110) and irradiates light onto one side of the cartridge housing unit (110) to indicate the treatment range of the ultrasonic generator unit (120).

[0133] The lamp part (210) for indicating the treatment range irradiates light downward from the upper side of the cartridge housing part (110) while the window part (110a) is in contact with the patient's skin, thereby irradiating light corresponding to the treatment range on one side of the cartridge housing part (110), and irradiating light on the patient's skin to form a line beam having a length corresponding to the treatment range.

[0134] The practitioner can easily check the treatment range by the range of light irradiated on one side of the cartridge housing (110) or the length of the line beam irradiated on the patient's skin.

[0135] The lamp unit (210) for indicating the treatment range is mounted on the inner surface of each of the two side surfaces of the handpiece casing unit and irradiates light on both sides of the cartridge housing unit (110) to indicate the treatment range of the ultrasonic generator unit (120).

[0136] During the procedure, the practitioner can easily check the procedure range according to the movement range of the ultrasonic generator (120) regardless of the procedure posture or procedure location by the light generated by the lamp unit (210) for indicating the procedure range on each side of the cartridge housing unit (110).

[0137] On the side of the cartridge housing (110), a light guide (111) is provided to guide the light of the lamp (210) for indicating the treatment range so that a line beam in the shape of a line is irradiated on the patient's skin.

[0138] The light guide part (111) includes a first light guide side wall part (111a) and a second light guide side wall part (111b) that are spaced apart from the direction in which light is irradiated to form an optical path through which light travels.

[0139] The space between the first light guide side wall (111a) and the second light guide side wall (111b) has an open shape toward the upper side and the lower side.

[0140] As an example, the light guide portion (111) is formed in a groove shape with the upper and lower sides open by being dug into the side of the cartridge housing portion (110), and a first light guide side wall portion (111a) and a second light guide side wall portion (111b) are formed facing each other inside the groove.

[0141] Although not shown, the first light guide side wall portion (111a) and the second light guide side wall portion (111b) may be formed in a form in which they are vertically erected on the side of the cartridge housing portion (110) and protrude so as to face each other.

[0142] The lamp part (210) for indicating the treatment range is located on the upper side between the first light guiding side wall part (111a) and the second light guiding side wall part (111b) and irradiates light downwards to allow light to pass between the first light guiding side wall part (111a) and the second light guiding side wall part (111b).

[0143] On the upper side of the first light guide side wall (111a) and the second light guide side wall, a first light guide protrusion (111c) and a second light guide protrusion (111d) are positioned so as to protrude to prevent the light generated from the lamp (210) for indicating the treatment range from spreading.

[0144] The first light guiding protrusion (111c) and the second light guiding protrusion (111d) are formed to protrude more than the first light guiding side wall (111a) and the second light guiding side wall, respectively, so that the light generated from the lamp part (210) for indicating the treatment range does not spread to the outside but passes between the first light guiding side wall (111a) and the second light guiding side wall.

[0145] The light guide unit (111) is positioned on each side of the cartridge housing unit (110) and guides the light generated from the lamp unit (210) for indicating the treatment range on each side of the cartridge housing unit (110) to indicate the treatment range on each side of the cartridge housing unit (110) and form a line beam having the same length as the treatment range on the patient's skin.

[0146]

[0147] Meanwhile, the lamp unit (210) for indicating the treatment range intuitively displays the equipment status during the treatment by generating light of different colors depending on the operating status of the ultrasonic generating cartridge (100), thereby allowing the operator to easily check the equipment status.

[0148] The lamp unit (210) for indicating the treatment range can display the following conditions with different colors of light: a standby state before treatment, i.e., a standby state in which the window unit (110a) is in contact with the skin and it has not been confirmed that the window unit (110a) is completely in contact with the skin; a treatment preparation state in which the light sensor unit (160) is in contact with the skin; a treatment-in-progress state in which the ultrasound generator (120) is moving and the treatment is being performed; and an operation error state.

[0149] Operational errors may include various types of errors, such as communication errors with the control body (300), coupling errors of the cartridge (100) for generating ultrasonic waves, or short circuits of the connecting cable (10).

[0150] For example, the lamp unit (210) for indicating the treatment range indicates the standby state with blue light, the treatment preparation state with green light, the treatment in progress state with yellow light, and the operation error state with red light.

[0151]

[0152] In addition, the lamp unit (210) for indicating the treatment range can be used as auxiliary lighting to detect the contact state of the window unit (110a) by irradiating light on the patient's skin with the light sensor unit (160).

[0153] When the treatment environment is dark, there is a problem in that the amount of light entering through the window part (110a) is small, and the light sensor part (160) located within the cartridge housing part (110) cannot accurately detect that the window part (110a) is in complete contact with the skin.

[0154] If the treatment environment is dark and the amount of light entering through the window part (110a) is small, even if the window part (110a) is not completely covered by the skin, light is not detected by the light sensor part (160), so even if the window part (110a) is not in contact with the skin, it may be falsely detected as being in contact with the skin.

[0155] The lamp part (210) for indicating the treatment range guides light through the side of the cartridge housing part (110) and irradiates it directly onto the skin to indicate the treatment range, and some of the light irradiated onto the skin enters the window part (110a), and the light sensor part (160) can check the state in which the window part (110a) is in close contact with the patient's skin through the light irradiated from the lamp part (210) for indicating the treatment range and entering through the window part (110a).

[0156] The lamp unit (210) for indicating the treatment range irradiates light onto the patient's skin, and when the window unit (110a) is separated from the skin, some of the light is introduced into the cartridge housing unit through the window unit (110a), and the light sensor unit (150) detects it.

[0157] When the treatment environment is dark, light irradiated onto the skin from the lamp unit (210) for indicating the treatment range can be detected by the light sensor unit (160) by entering the cartridge housing unit (110) through the window unit (110a), so that only when the window unit (110a) is in close contact can light not be detected by the light sensor unit (160), and thus the state in which the window unit (110a) is completely in close contact with the skin can be accurately detected through the light sensor unit (160).

[0158] In addition, the cartridge housing part (110) is provided with a guide slope (112) that is inclined toward the window part (110a) on the lower side and guides the light irradiated from the lamp part (210) for indicating the treatment range to the window part (110a), so that more light from the lamp part (210) for indicating the treatment range irradiated onto the skin through the side of the cartridge housing part (110) can be introduced into the cartridge housing part (110) through the window part (110a).

[0159] The guide slope (112) is formed to be inclined inward toward the window section (110a) on each side of the cartridge housing section (110) where the light of the lamp section (210) for indicating the treatment range is irradiated, so that some of the light of the lamp section (210) for indicating the treatment range irradiated on the side of the cartridge housing section (110) can be guided toward the window section (110a).

[0160] The guide slope (112) is formed in a form that is dug inward based on the side of the cartridge housing portion (110) to increase the area of ​​light irradiated onto the skin, thereby allowing the practitioner to easily check the treatment range, and at the same time, to allow light to smoothly enter the cartridge housing portion (110) through the window portion (110a) that is not in contact with the skin, thereby increasing the amount of light entering the cartridge housing portion (110) when the window portion (110a) is not in contact with the skin.

[0161] The guide slope (112) increases the amount of light entering the cartridge housing (110) through the window portion (110a) that is not in contact with the skin, so that even in a dark treatment environment, the state in which the window portion (110a) is in complete contact with the skin can be accurately detected by the light sensor portion (160).

[0162]

[0163] The present invention can accurately check the contact state between the window part (110a) and the skin by detecting the amount of light entering through the window part (110a) that comes into contact with the skin using a light sensor, thereby preventing accidents in which damage to skin tissue or burns occur to the skin due to separation between the window part (110a) and the skin during the procedure, and can greatly improve safety during the procedure.

[0164] The present invention prevents the patient's skin from being injured, such as burns, by performing repeated procedures at the same procedure location by confirming the procedure location and procedure range, thereby significantly improving procedure safety.

Furthermore, those skilled in the art will appreciate that numerous modifications and variations are possible without departing from the scope of the present invention.
