Description

Handpiece for generating ultrasound to detect the treatment location and ultrasound generating device equipped therewith

[0001] The present invention relates to a handpiece for generating ultrasonic waves that detects a treatment location and an ultrasonic generator having the same, and to a handpiece for generating ultrasonic waves that detects a treatment location and prevents overlapping treatments at the same treatment location by confirming the treatment location, and to 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] The handpiece for generating ultrasound irradiates the patient's skin with high-intensity focused ultrasound, so if ultrasound is generated more than twice in the same location during the procedure, it may cause burns or wounds on the skin.

[0011] However, conventional ultrasound generating cartridges have no means of confirming the treatment location, so there is a risk that the practitioner may perform the same treatment at the same location on the patient's skin repeatedly, and there is a problem that the treatment efficiency is reduced because the treatment location cannot be confirmed accurately.

[0012] A prior patent related to the present invention is Korean Patent Registration No. 1307551, “Handpiece of ultrasonic device” (registered on September 5, 2013).

[0013] An object of the present invention is to provide an ultrasound generating handpiece that detects a treatment location to prevent overlapping treatments at the same treatment location by confirming the treatment location.

[0014] In order to achieve the above-described object of the present invention, one embodiment of a handpiece for generating ultrasound for detecting a treatment position is characterized by including an ultrasound generating cartridge having an ultrasound generating unit for irradiating ultrasound to the skin through a window unit in a cartridge housing unit having a window unit that comes into contact with the skin, a handpiece body casing unit in which the ultrasound generating cartridge is detachably mounted and connected to a control unit, and a treatment position detecting unit provided in the handpiece body casing unit and detecting the treatment position of the ultrasound generating cartridge.

[0017] In the present invention, the handpiece main body casing part may be combined with various types of ultrasonic generating cartridges having ultrasonic generating units having different intensities or treatment ranges, and the control main body may store the movement distance for the next treatment location after one treatment depending on the type of the ultrasonic generating cartridge.

[0018] In the present invention, the treatment position detection unit may further include a wheel raising / lowering unit that raises / lowers the contact wheel unit to contact the skin, and a contact sensor unit that detects that the contact wheel unit has contacted the skin.

[0019] In the present invention, the contact sensor unit is a load sensor that detects a load generated when the contact wheel unit comes into contact with the skin, and the elevating unit raises and lowers the contact wheel unit when a load value higher than a preset value is detected by the load sensor, and when a load higher than a preset range is detected by the load sensor, the contact wheel unit is raised and lowered so that the height of the contact wheel unit can be adjusted so that a load within the preset range is generated by the load sensor.

[0020] In the present invention, the treatment position detection unit may further include a wheel rotation unit that rotates the contact wheel unit to change the rolling direction of the contact wheel unit.

[0021] In the present invention, the treatment position detection unit may further include a wheel rotation switch unit that is provided in the handpiece main body casing unit and is operated by the operator to control the operation of the wheel rotation unit.

[0022] In the present invention, the wheel rotation switch unit is a rotary knob switch that rotates on a plane to change the rotation direction of the contact wheel unit, and the treatment position detection unit may further include a movement direction display unit that displays the movement direction of the contact wheel unit changed by the operation of the wheel rotation switch unit.

[0023] In the present invention, the movement direction indicator may include a plurality of first movement direction indicators positioned radially from the rotation center of the rotary knob switch on the upper surface of the handpiece body casing part around the outer circumference of the rotary knob switch, and a second movement direction indicator positioned on the rotary knob switch and supporting the movement direction of the contact wheel part by indicating any one of the plurality of first movement direction indicators.

[0024] In the present invention, the treatment position detection unit may further include a ball joint unit that connects a wheel supporter that supports the position of the contact wheel unit to the handpiece main body casing unit so as to be rotatable in a 360-degree direction, and a movement direction detection unit that detects the direction in which the contact wheel unit moves.

[0025] In the present invention, the wheel rotation unit can automatically rotate the contact wheel unit so that the contact wheel unit is positioned in the direction of movement of the ultrasonic generating cartridge detected by the direction of movement detection unit.

[0026] In the present invention, the movement direction detection unit may include a direction detection ring body part having a hollow portion through which the wheel support body penetrates and an inner surface thereof is positioned spaced apart from an outer surface of the wheel support body, and which is connected and fixed to the handpiece main body casing part, and a plurality of direction detection connecting parts positioned to protrude radially spaced apart from the inner surface of the direction detection ring body part and elastically support an outer surface of the wheel support body.

[0029] The present invention has the effect of preventing the patient's skin from being injured, such as burns, by confirming the location of the procedure and preventing the procedure from being performed repeatedly at the same location during the procedure, thereby greatly improving the safety of the procedure.

[0030] In addition, the present invention has the effect of increasing treatment efficiency and shortening treatment time by enabling treatment to be performed without overlapping treatment areas while confirming the treatment area where the treatment has been performed.

[0060] 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.

[0061] FIG. 1 is a perspective view illustrating an embodiment of an ultrasonic generator according to the present invention. Referring to FIG. 1, an embodiment of an ultrasonic generator according to the present invention includes an ultrasonic generator handpiece (200) that comes into contact with skin and irradiates ultrasonic waves to the contacted skin, and a control body (300) that is connected to the ultrasonic generator handpiece (200) by a handpiece cable body (1100) to control the operation of the ultrasonic generator handpiece (200).

[0062] The handpiece (200) for generating ultrasound includes an ultrasonic cartridge (100) having an ultrasonic generator that irradiates ultrasound to the skin through a window (110a) positioned within a cartridge housing (110) having a window (110a) that comes into contact with the skin, and a handpiece body casing (200a) in which the ultrasonic cartridge (100) is detachably mounted and connected to a control body (300).

[0063] The handpiece main body casing (200a) electrically connects the control main body (300) and the ultrasonic generator with a connection cable (10) so that the operation of the ultrasonic generator can be controlled through the control main body (300).

[0064] As an example, the cartridge (100) for ultrasonic generation is coupled by sliding to the tip of the handpiece body casing part (200a), and the coupling is completed by being locked by the cartridge locking part (200a) at the final coupling position.

[0065] 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.

[0066] The cartridge (100) for generating ultrasound can be detachably coupled to the handpiece body casing part (200a) using the coupling structure of the cartridge applied to a known handpiece (200) for generating ultrasound used in skin treatment.

[0067] The control body (300) can be implemented by various modifications of a known ultrasonic generator that irradiates ultrasonic waves to the skin for skin treatment, and a more detailed description thereof will be omitted.

[0068] An embodiment of a handpiece (200) for generating ultrasound includes an embodiment of a handpiece (200) for generating ultrasound that detects a treatment position according to the present invention, which is described below.

[0069]

[0070] Meanwhile, FIG. 2 is a perspective view illustrating an embodiment of an ultrasonic generation handpiece (200) for detecting a treatment position according to the present invention, FIG. 3 is a cross-sectional view illustrating an embodiment of an ultrasonic generation handpiece (200) for detecting a treatment position according to the present invention, and FIG. 4 is an enlarged view of part A of FIG. 3.

[0071] Referring to FIGS. 2 to 4, one embodiment of an ultrasonic generating handpiece (200) for detecting a treatment position according to the present invention is described in detail below.

[0072] The cartridge housing (110) has an ultrasonic generator that generates ultrasonic waves located inside, and is filled with a liquid medium for transmitting ultrasonic waves generated from the ultrasonic generator.

[0073] In addition, the lower surface of the cartridge housing (110) is provided with a window (110a) that is in close contact with the patient's skin and through which ultrasonic waves generated from an ultrasonic generator (120) located inside pass.

[0074] 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.

[0075] As an example, the ultrasonic generator is positioned movably within the cartridge housing (110) and includes a known ultrasonic transducer that generates ultrasonic waves.

[0076] More specifically, the ultrasonic generator (120) includes an ultrasonic transducer, and the ultrasonic transducer generates high intensity focused ultrasound (HIFU) that generates heat by applying it to the skin muscle layer, thereby inducing degeneration and regeneration of skin tissue, thereby improving skin wrinkles and increasing skin elasticity.

[0077] 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, so that the ultrasonic waves generated from the ultrasonic generator (120) moving back and forth in a straight line can be stably transmitted.

[0078] The handpiece body casing (200a) is connected to the 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).

[0079] An example of an actuator (150) is one that moves an ultrasonic generator (120) in a linear reciprocating manner.

[0080] And, as an example, the ultrasonic generator (120) is connected to an actuator (150) and moves back and forth in a straight line within a preset movement range.

[0081] Inside the handpiece body casing (200a), an LED board (201) for indicating the operating status, an operation button (202), and a handpiece main board (203) in which the LED board (201), operation button (202), and control body (300) are electrically connected are provided.

[0082] The handpiece main board (203) operates the actuator according to the control of the control body (300), supplies power to the ultrasonic generator (120) according to the on / off of the operation button (202), receives a signal detected from the ultrasonic generator (120) and transmits it to the control body (300), and can display the operating status by turning on the LED of the LED board (201).

[0083] An actuator connection part (140) is located inside the cartridge housing part (110) to connect the actuator (150) and the ultrasonic generator (120) so that the ultrasonic generator (120) can be moved by the operation of the actuator (150).

[0084] 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 (150) and moves in a straight line by the operation of the actuator (150), 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 of both sides 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 (150) to the slider (141).

[0085] The Java member (143) forms a sealed space inside, and an actuator (150) can be inserted inside through the sealed space and connected to the slider (141).

[0086] 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).

[0087] When the slider (141) moves, one of the two Java members (143) is unfolded and the other Java member (143) is folded, so that the slider (141) can move back and forth in a straight line along the movement guide pin member (142).

[0088] The power transmission unit (144) is, for example, a magnet or magnetic body that can be magnetically attached to the actuator (150).

[0089] That is, the slider (141) is magnetically connected to the actuator (150) through the actuator connection part (140), and by the operation of the actuator (150), 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.

[0090] The actuator (150) includes a moving rod member (211) that is inserted into the interior of the Java member (143) and magnetically attached to the power transmission member (144).

[0091] 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.

[0092] 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.

[0093] It is to be noted that the actuator (150) can be implemented in various modified forms as a known linear actuator.

[0094] As an example, the handpiece main body casing part (200a) is connected to the control main body (300) via a connection cable (10) so that the operation of the ultrasonic generator and actuator (150) is controlled.

[0095] The handpiece main body casing (200a) and the ultrasonic generating cartridge (100) are each provided with a plurality of connection terminals 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 connected to the handpiece main body casing (200a), the ultrasonic generating unit (120) is electrically connected to the control main body (300) through the connection terminals, so that the operation can be controlled through the control main body (300).

[0096]

[0097] Meanwhile, the handpiece main body casing part (200a) includes a treatment position detection part (400) that detects the treatment position of the ultrasonic generating cartridge (100).

[0098] The treatment location detection unit (400) detects that the ultrasonic generating unit in the ultrasonic generating cartridge (100) has moved after one treatment has been completed by operating the ultrasonic generating unit, and confirms the moved location to notify the operator.

[0099] In more detail, the treatment position detection unit (400) is an example that includes a contact wheel unit (410) that contacts the skin together with the window unit (110a) of the ultrasonic generating cartridge (100) while it is in contact with the skin and rotates when the ultrasonic generating cartridge (100) moves, and a scroll encoder unit (420) that detects the rotation of the contact wheel unit (410) to check the movement distance of the ultrasonic generating cartridge (100).

[0100] The contact wheel part (410) is positioned so as to come into contact with the patient's skin when the window part (110a) of the ultrasonic generating cartridge (100) comes into contact with the patient's skin.

[0101] The contact wheel part (410) comes into contact with the patient's skin together with the window part (110a), and when the window part (110a) moves while in contact with the patient's skin, it comes into contact with the skin and rotates due to friction with the skin.

[0102] The scroll encoder unit (420) can detect the amount of rotation of the contact wheel unit (410) and check the movement distance of the cartridge (100) for generating ultrasonic waves.

[0103] In addition, one embodiment of the handpiece (200) for generating ultrasound for detecting a treatment position according to the present invention further includes a treatment position notification unit (500) provided in the handpiece main body casing unit (200a) and notifying the operator when the treatment position detection unit (400) detects that the ultrasonic generation cartridge (100) has moved to a preset distance.

[0104] The treatment location notification unit (500) includes, for example, a lamp unit that emits light or a speaker unit that outputs a notification sound, and when the treatment location detection unit (400) detects that the cartridge (100) for generating ultrasound has moved a preset distance, it emits light or outputs a notification sound to accurately notify the operator of the next treatment location.

[0105] The treatment location detection unit (400) can detect the distance to the next treatment location when the window unit (110a) of the ultrasonic generating cartridge (100) moves in contact with the skin.

[0106] In the control body (300), the distance to the next treatment location after one treatment operation of the ultrasonic generator is preset and stored in consideration of the ultrasonic intensity and treatment range of the ultrasonic generator.

[0107] The handpiece main body casing (200a) can be combined with various types of ultrasonic generating cartridges equipped with ultrasonic generating units having different intensities or treatment ranges, and the control main body (300) stores the movement distance for the next treatment location after one treatment depending on the type of ultrasonic generating cartridge (100).

[0108] The control body (300) stores the movement distance to the next treatment location after one treatment by the operation of the ultrasonic generator depending on the type of ultrasonic generator cartridge (100) coupled to the handpiece body casing (200a).

[0109] The control body (300) confirms the type of ultrasonic generating cartridge (100) coupled with the handpiece body casing part (200a) through connection with the connection terminal.

[0110] And, when the control body (300) confirms by the rotation amount of the contact wheel (410) that the ultrasonic generating unit is operated while the window unit (110a) is in contact with the skin and that the ultrasonic generating cartridge, i.e. the type of ultrasonic generating cartridge, moves to the next treatment position after one treatment, the control body (300) notifies the operator through the treatment position notification unit (500) so that the ultrasonic generating cartridge can be stopped at the treatment position and the next treatment can be performed immediately.

[0111]

[0112] Meanwhile, the treatment position detection unit (400) further includes a wheel raising / lowering unit (430) that raises / lowers the contact wheel unit (410) to bring it into contact with the skin, and a contact sensor unit (not shown) that detects that the contact wheel unit (410) has come into contact with the skin.

[0113] The contact sensor unit (not shown) can be implemented in various ways as a known contact sensor, such as a load sensor that detects contact by detecting a load when the contact wheel unit (410) is pressed when the contact wheel unit (410) is in contact with the skin, or a contact sensor that detects contact by a change in electrostatic capacity when the contact wheel unit (410) is in contact with the skin, so a more detailed description is omitted.

[0114] The wheel raising / lowering unit (430) raises and lowers the contact wheel unit (410) according to the treatment area of ​​the patient while the window unit (110a) of the ultrasonic generating cartridge (100) is in contact with the skin, thereby bringing it into contact with the skin.

[0115] The contact wheel part (410) may be separated from the skin due to skin curvature, the patient's posture, the practitioner's posture, etc. while the window part (110a) of the ultrasonic generating cartridge (100) is in contact with the skin.

[0116] The wheel raising / lowering unit (430) raises and lowers the contact wheel unit (410), and when the contact wheel unit (410) comes into contact with the skin by a contact sensor unit (not shown), the operation is stopped, so that the contact wheel unit (410) can be positioned in a state of contacting the skin.

[0117] When the contact sensor unit (not shown) detects that the contact wheel unit (410) is not in contact with the skin while the window unit (110a) of the ultrasonic generating cartridge (100) is in contact with the skin, the wheel raising / lowering unit (430) lowers the contact wheel unit (410) so that the contact wheel unit (410) can come into contact with the skin.

[0118] The contact sensor unit (not shown) is a load sensor, i.e., a load cell, that detects the load generated when the contact wheel unit (410) comes into contact with the skin, and the elevation unit adjusts the height of the contact wheel unit (410) so that a load within a preset range is generated in the load sensor.

[0119] If the contact wheel part (410) applies excessive pressure to the skin, pain may occur on the skin. Therefore, if a load value exceeding a preset value is detected by the load sensor, the wheel raising / lowering part (430) raises / lowers the contact wheel part (410).

[0120] The wheel raising / lowering unit (430) raises and lowers the contact wheel unit (410) when a load higher than a preset range is detected by the load sensor, and lowers the contact wheel unit (410) when a load lower than a preset range is detected by the load sensor, so that the contact wheel unit (410) can roll and rotate while in contact with the skin with an appropriate pressure.

[0121]

[0122] In addition, the contact wheel part (410) is positioned to roll and rotate in the width direction of the window part (110a), as an example.

[0123] After the operator operates the ultrasonic generator to complete one treatment, the operator can move the ultrasonic generator cartridge (100) in the width direction to perform the treatment at the next treatment location.

[0124] The treatment position detection unit (400) further includes a wheel rotation unit (440) that rotates the contact wheel unit (410) to change the rolling direction of the contact wheel unit (410), i.e., the direction in which it rotates when in contact with the skin, so that the moving direction of the ultrasonic generating cartridge (100) can be varied to determine the next treatment position.

[0125] The wheel rotation part (440) can change the direction in which the contact wheel part (410) rolls and rotates by rotating the scroll encoder part (420) to which the contact wheel part (410) is rotatably coupled around a rotation axis erected on the skin that is in contact with it.

[0126]

[0127] The wheel rotation part (440) can rotate the contact wheel part (410) around a vertically erected rotation axis to control the direction of movement in which the contact wheel part (410) rolls in contact with the skin.

[0128] The wheel rotation part (440) is positioned on the upper side of the scroll encoder part (420) and rotates the scroll encoder part (420) around an erected rotation axis, and is connected to the wheel raising / lowering part (430), as an example.

[0129] The wheel raising / lowering unit (430) can raise / lower the contact wheel unit (410) by raising / lowering the wheel rotation unit (440) and the scroll encoder unit (420) together.

[0130] The direction of movement of the contact wheel part (410) is adjusted to be the same as the direction of movement of the ultrasonic generating cartridge (100) that moves to the next treatment location during treatment.

[0131] The treatment position detection unit (400) is provided in the handpiece body casing unit (200a) and further includes a wheel rotation switch unit (450) that controls the operation of the wheel rotation unit (440) that is operated by the operator to adjust the movement direction of the contact wheel unit (410).

[0132] As an example, the wheel rotation switch unit (450) is a rotary knob switch (451) that rotates on a plane to change the rotation direction of the contact wheel unit (410).

[0133] The treatment position detection unit (400) further includes a movement direction display unit (460) that displays the movement direction of the contact wheel unit (410) changed by the operation of the wheel rotation unit (440) by the operation of the wheel rotation switch unit (450).

[0140] FIG. 4 is an enlarged view of part A of FIG. 3, FIG. 5 is a perspective view showing an embodiment of a treatment position detection unit (400) in an embodiment of an ultrasonic generating handpiece (200) for detecting a treatment position according to the present invention, and FIG. 6 is a cross-sectional view showing an embodiment of a treatment position detection unit (400) in an embodiment of an ultrasonic generating handpiece (200) for detecting a treatment position according to the present invention.

[0141] Referring to FIGS. 4 to 6, the treatment position detection unit (400) further includes a wheel support spring unit (470) that elastically supports the contact wheel unit (410).

[0142] In more detail, the treatment position detection unit (400) further includes a wheel mounting bracket unit (472) that is movably connected to the encoder housing unit (471) and on which the contact wheel unit (410) is rotatably mounted, and a wheel support spring unit (470) that is positioned within the encoder housing unit (471) and elastically supports the wheel mounting bracket unit (472).

[0143] The spring part (470) for wheel support elastically supports the contact wheel part (410) so that the contact wheel part (410) can maintain contact with the skin at an appropriate pressure.

[0144]

[0145] In addition, the treatment position detection unit (400) further includes a ball joint unit (480) that connects the contact wheel unit (410) to the handpiece body casing unit (200a) so that it can rotate 360 ​​degrees, and a movement direction detection unit (490) that detects the direction in which the contact wheel unit (410) moves.

[0146] The movement direction detection unit (490) has a hollow portion through which the scroll encoder unit (420) or the wheel raising / lowering unit (430) passes and the inner surface thereof is positioned spaced apart from the outer surface of the scroll encoder unit (420) or the outer surface of the wheel raising / lowering unit (430), and includes a direction detection ring body unit (491) that is connected and fixed to the handpiece main body casing unit (200a), and a plurality of direction detection connecting portions (492) that are positioned so as to protrude radially spaced apart from the inner surface of the direction detection ring body unit (491) and elastically support the outer surface of the scroll encoder unit (420) or the outer surface of the wheel raising / lowering unit (430).

[0147] A wheel supporter that supports the position of the operating wheel, such as a scroll encoder unit (420) or a wheel raising / lowering unit (430), is positioned through the hollow portion of the direction-sensing ring body (491).

[0148] The ball joint part (480) is located on the upper side of the wheel raising / lowering part (430) and can rotate the wheel raising / lowering part (430), the wheel rotation part (440), and the scroll encoder part (420) by a radius of 360 degrees around the ball, respectively.

[0149] In addition, the rotation radius of the contact wheel part (410) by the ball joint part (480) is limited by the direction-sensing ring body part (491).

[0150] Hereinafter, an example of the operation of the direction detection connection part (492) is described in an embodiment in which the wheel raising / lowering part (430) is positioned to penetrate the hollow part of the direction detection ring body part (491) as shown in the drawing.

[0151] If the direction of movement of the contact wheel unit (410) is different from the direction of movement of the ultrasonic generating cartridge (100) moved by the operator, a reaction force is generated in the opposite direction to the direction of movement of the ultrasonic generating cartridge (100) while the contact wheel unit (410) does not rotate, and the movement direction detection unit (490) detects the direction in which the operator attempts to move the ultrasonic generating cartridge (100) when one of the plurality of direction detection connecting units (492) is pressed by the wheel raising / lowering unit (430) due to the reaction force.

[0152] The wheel rotation unit (440) automatically rotates the contact wheel unit (410) so that the contact wheel unit (410) is positioned in the direction of movement of the ultrasonic generating cartridge (100) detected by one of the plurality of direction detection units (492).

[0153] When the direction of movement of the contact wheel part (410) matches the direction of movement of the ultrasonic generating cartridge (100) moved by the operator, no reaction force is generated, and when the contact wheel part (410) rolls, none of the multiple direction detection connecting parts (492) are pressed.

[0154] That is, when the operator generates a force to move the cartridge (100) for generating ultrasound, the movement direction detection unit (490) detects the movement direction of the cartridge (100) for generating ultrasound and automatically rotates the contact wheel unit (410) with the wheel rotation unit (440) to position it in line with the movement direction of the cartridge (100) for generating ultrasound, thereby eliminating the need for the operator to separately operate the contact wheel unit (410) to change the movement direction, thereby increasing the convenience of the procedure.

[0155] The contact wheel part (410) automatically adjusts its movement direction to match the movement direction of the ultrasonic generating cartridge (100) by the operator, and can accurately detect the next treatment location in the movement direction of the ultrasonic generating cartridge (100).

[0156]

[0157] The present invention can prevent duplicate procedures at the same procedure location by confirming the procedure location, thereby preventing the occurrence of burns or other injuries to the patient's skin due to duplicate procedures at the same procedure location during the procedure, and can greatly improve the safety of the procedure.

[0158] In addition, the present invention can increase treatment efficiency and shorten treatment time by performing treatment without overlapping treatment areas while confirming the treatment area where the treatment has been performed.

[0159] While the present invention has been described in detail using preferred embodiments, the scope of the present invention is not limited to the specific embodiments described above, and should be interpreted in accordance with the appended claims. Furthermore, those skilled in the art will appreciate that numerous modifications and variations are possible without departing from the scope of the present invention.
