When the treatment handpiece 210 is exposed to the outside, the second connecting rod CR2 and the first rotating part R1 may be coupled.

At least one of the treatment transducers 314 may be provided in the cartridge body 312 to be movable. That is, the treatment transducer 314 may be installed to be movable inside the first and second cartridges 310 and 320 so that the irradiation position of the HIFU is variable. In this case, a driving device such as a step motor for moving the treatment transducer 314 may be provided inside the procedure handpiece 210. The driving device may cause the HIFU to be irradiated while moving the treatment transducer 314 in a left-right direction, so that a plurality of thermal lesions 12 may be formed to be spaced apart from each other along the same line on the skin tissue.

Here, a cooling fluid for cooling heat generated by the operation of the treatment transducer 314 may be provided. In one embodiment, each of the first and second cartridges 310 and 320 may be provided so that cooling water may be filled therein. For example, as illustrated in FIG. 4, a cooling fluid may be injected into the first cartridge 310 by providing a first through hole TH1 or a second through hole TH2. In addition, the through-holes may be blocked by using the first stopper C1 or the second stopper C2 to prevent the coolant inside the first cartridge 310 from flowing out through the through holes.

A detailed description of the control unit 400 will be described later.

With continued reference to FIG. 4 and the like, in the high-intensity focused ultrasound apparatus 10 according to an embodiment of the present invention, a swing motion is converted into a linear motion, so that the therapeutic transducer 314 may be moved. In this case, a function block for converting a swing motion into a linear motion may be referred to as a conversion unit, and in one embodiment, the conversion unit may be understood as a concept including a first connecting rod CR1 and a support 316. Here, the support 316 is coupled to the treatment transducer 314 and may be moved in a linear direction together with the treatment transducer 314. Meanwhile, the support 316 and the treatment transducer 314 may be integrally formed, and in this case, it may be understood that the treatment transducer 314 includes a function of the support 316. In addition, in one embodiment, the support 316 is coupled to the first guide rail G1, and the support 316 may perform linear motion along the first guide rail G1.

In one embodiment, the first connecting rod CR1 is coupled to the support 316 and performs a swing motion. The term'swing motion' used throughout this specification means that a point on a straight line is fixed to form an axis of rotation, and the straight line is rotated within a predetermined angular range, so that another point on the straight line reciprocates along an arc having a predetermined radius. Means exercise. That is, a point on one side of the first connecting rod (CR1) becomes a rotation axis, and a point connected to the support 316 from the other side of the first connecting rod (CR1) reciprocates along a predetermined arc, so that the first connecting rod (CR1) is It can be understood as doing a swing exercise. Meanwhile, in another embodiment, one side of the first connecting rod CR1 may be coupled to the first rotating part R1. In this case, the rotation shaft is not a point on one side of the first connecting rod CR1, but the first rotating part R1 ) Will be a point. In addition, the first rotating part R1 and the first connecting rod CR1 may be integrally formed, and even in this case, one point serving as the rotating shaft becomes one point on the first rotating part R1. However, a predetermined clearance may exist between the first rotating part R1 and the first cover 312c1, and the first rotating part R1 may not form a perfect circular shape. May not be fixed.

In one embodiment, the other side of the first connecting rod CR1 is coupled to the support 316 so as to be rotatable. That is, the first connecting rod (CR1) and the support 316 can be coupled so that the relative angle between the variable, for example, the first connecting pin between the other side of the first connecting rod (CR1) and the support 316 Can be combined by (P1).

Meanwhile, in an embodiment, the position of the first connection pin P1 on the support 316 may be changed. For example, the first connection pin P1 may be coupled to a first pin groove formed long in a direction perpendicular to the linear movement direction of the support 316, and the first connection pin P1 may be moved along the first pin groove. Further, although not shown, the length of the first connecting rod CR1 may be variable, and in this case, the first connecting pin P1 may be fixed to a point on the support 316.

Accordingly, since the swing motion of the first connecting rod CR1 is converted into a linear motion of the support 316 and the treatment transducer 314 can be moved in a linear direction, convenience of the procedure may be improved. In addition, despite the swing movement of the first connecting rod CR1, the treatment transducer 314 can irradiate high-intensity focused ultrasound in the same direction, and a thermal lesion (12 in FIG. 5) caused by the high-intensity focused ultrasound Since it can be formed at a certain depth from the skin surface, the safety of the procedure can be improved.

In one embodiment, the first cartridge may be implemented as a combination of the cartridge body 312 and the first cover 312c1. That is, the cartridge body 312 serves as a kind of housing, and after components such as the treatment transducer 314 are disposed inside the first cartridge, the first cover 312c1 may be coupled to the cartridge body 312. Here, the first rotating part R1 is coupled to the first cover 312c1 so as to be rotatable on the first cover 312c1. In addition, a region of the first cover 312c1 that contacts or faces the first rotation part R1 may have a shape corresponding to the shape of the first rotation part R1. In addition, the first rotating part R1 may have a generally spherical shape.

Accordingly, despite the rotation of the first rotating part R1, the first rotating part R1 and the first cover 312c1 may continue to contact or maintain a certain distance, and as a result, the first rotating part R1 and the first The area surrounded by the cover 312c1 and the cartridge body 312 may be sealed. In addition, in order to improve the degree of sealing, a first sealing member 312s1 may be provided at a joint portion between the first cover 312c1 and the cartridge body 312. In addition, a second sealing member 312s2 may be provided at a coupling portion between the first cover 312c1 and the first rotating part R1. At this time, the first sealing member 312s1 or the second sealing member 312s2 may be implemented as a conventional O-ring.

In one embodiment, an auxiliary cover 312c3 may be further provided. For example, in a state in which the first rotating part R1 is placed in the first cover 312c1, the auxiliary cover 312c3 is coupled from the upper direction of the first rotating part R1 toward the first cover 312c1. (R1) may be stably installed on the first cover 312c1. At this time, the auxiliary cover 312c3 may also perform a function of fixing the second sealing member 312s2 in the correct position.

Meanwhile, the first rotating part R1 may have a cylindrical shape. That is, the first connecting rod CR1 may have a circular shape only on the cross-section of the first rotating portion R1 cut into a plane in which the first connecting rod CR1 swings. Even in this case, the space between the first rotating part R1 and the first cover 312c1 may be tightly sealed despite the rotation of the first rotating part R1. However, in the case where the first rotating part R1 has a cylindrical shape, it should be considered that the sealing degree between the upper or lower surface of the cylinder and the first cover 312c1 may be lower than in the case described above.

On the other hand, although not shown, the upper surface of the first rotating part R1 and the upper surface of the first cover 312c1 are covered with a sheet made of a flexible material, or the lower surface of the first rotating part R1 and the first cover 312c1 are covered. Airtightness can also be secured by covering the lower surface.

In one embodiment, the second cover 312c2 is further provided above the auxiliary cover 312c3 so that the first rotating part R1 is positioned more stably. In addition, a circuit board CB that is electrically connected to the first sensor, the second sensor, and the treatment transducer 314 may be provided in a space between the second cover 312c2 and the first cover 312c1. In addition, a terminal portion 312c electrically connected to the circuit board (CB), a protrusion portion 312d or a fixing pin (PF) contributing to a stable coupling with the surgical handpiece 210 are provided on the second cover 312c2. I can.

Accordingly, the circuit board CB is protected so that foreign substances such as cooling fluid filled in the area surrounded by the first cover 312c1 and the cartridge body 312 do not come into contact with the circuit board CB, while maximizing space utilization to Can contribute to miniaturization of the product.

The first rotating part R1 of the high-intensity focused ultrasound treatment apparatus 10 according to an embodiment of the present invention is rotated by receiving a kinetic force from the treatment handpiece 210, and as a result, the first connecting rod CR1 swings. Perform. For example, the second connecting rod CR2 provided in the surgical handpiece 210 is coupled with the first rotating part R1, and the first rotating part R1 rotates as the position of the second connecting rod CR2 changes. Can be. In one embodiment, the second connecting rod CR2 may protrude outside the surgical handpiece 210 and be coupled to the first rotating part R1. Of course, although not shown, elements such as the protrusion R1-1 protruding from the first rotating part R1 may be connected in a manner that is inserted into the treatment handpiece 210. However, in the process of combining the surgical handpiece 210 and the first cartridge 310, an element providing a kinetic force to the first rotating part R1 and the first rotating part R1 are first combined, and other parts, such as a second cover. It is advantageous for stable and easy coupling to allow the 312c2 and the handpiece cover 212c to be coupled.

On the other hand, in a state in which the second connecting rod CR2 is coupled with the first rotating part R1, the swing movement of the second connecting rod CR2 is accompanied when the first rotating part R1 is rotated, and the rotation axis of the swing movement Is the same as the rotation axis of the first connecting rod CR1.

In one embodiment, one side of the second connecting rod CR2 may be moved along an arc. For example, a second connection pin P2 is coupled to one side of the second connecting rod CR2, and the second connection pin P2 is coupled to a second guide rail G2 provided with an arc-shaped guide line. One side of the second connecting rod CR2 may be moved along an arc as the connection pin P2 is movably coupled along the above-described guide line. In addition, a third connecting rod (CR3) is provided in the second rotating portion (R2) rotated by receiving the power provided from the driver 217, and the third connecting rod (CR3) is the aforementioned second connecting pin (P2). Can be brought into contact with. In this case, the distance between the rotation axis of the second rotation unit R2 and the second connection pin P2 may be variable. For example, a groove having a length greater than the diameter of the second connecting pin P2 is provided in the third connecting rod CR3, and the second connecting pin P2 is inserted into the groove. And the second connection pin P2 may be coupled. Accordingly, when the third connecting rod CR3 swings, the distance between the rotation axis of the second rotation part R2 and the second connection pin P2 is varied, and the second connecting rod CR2 may be moved, as a result. The second connecting rod CR2 and the first connecting rod CR1 perform a swing movement about the rotation axis of the first rotating part R1. Here, although not shown, the distance between the rotation axis of the second rotation unit R2 and the second connection pin P2 may be varied in such a manner that the length of the third connecting rod CR3 is variable.

Referring to FIG. 5, a principle in which the therapeutic transducer 314 moves linearly in the high intensity focused ultrasound apparatus 10 according to an embodiment of the present invention may be understood. That is, the operation of the actuator 217 causes the third connecting rod CR3 to swing, and the swing movement is performed by the second connecting rod CR2 and the first rotating part R1 to swing the first connecting rod CR1. Generate movement; In addition, the support 316 linearly moves according to the swing movement of the first connecting rod CR1, so that the treatment transducer 314 can be moved. On the other hand, the actuator 217 may control the operation of the treatment transducer 314 to irradiate the HIFU.

* As described above, the high-intensity focused ultrasound treatment apparatus 10 according to an embodiment of the present invention, the kinetic force provided from the treatment handpiece 210 is transmitted to the cartridges 310 and 320 to treat the transducer 314 It is possible to form a thermal lesion (12 in Fig. 5) while moving linearly. Accordingly, the cartridges 310 and 320 in which the treatment transducer 314 is movably provided can be made smaller than the conventional one, and the sealing degree inside the cartridge can be secured to a predetermined level.

On the other hand, the high-intensity focused ultrasound treatment apparatus 10 according to an embodiment of the present invention determines whether the first or second cartridges 310 and 320 normally contact or closely contact the skin tissue to be treated during the treatment, It is possible to control whether or not to irradiate high intensity focused ultrasound. More specifically, each of the first and second cartridges 310 and 320 may be provided with at least one contact sensor S1 and S2 disposed on a contact surface with a skin tissue during a procedure. For example, a skin contact surface in contact with the skin tissue of the subject to be treated is provided at the front end of the first cartridge 310, and a plurality of the contact sensors S1 and S2 are spaced apart from each other on the skin contact surface of the first cartridge 310 Can be deployed. In this case, the contact detectors S1 and S2 may include an optical sensor that detects whether an optical signal is received. Further, detection signals of each of the contact sensors S1 and S2 may be received by the control unit 400. In this case, when the first cartridge 310 is in close contact with the skin tissue during the procedure and detects that all of the contact detection sensors 316 are in close contact with the skin, the control unit 400 controls the first cartridge 310 ) Can be judged to be in close contact with the skin tissue. On the other hand, if even one of the contact detection sensors 316 does not detect that it is in close contact with the skin, the control unit 400 may determine that the first cartridge 310 is in abnormal contact with the skin tissue. Accordingly, the control unit 400 controls the actuator 217 so that HIFU irradiation of the treatment transducer 314 is performed only when the first cartridge 310 is in normal contact with the procedure handpiece 210 By doing so, it is possible to prevent the thermal lesion 12 of HIFU from being irradiated to tissues other than the desired skin tissue.

In one embodiment, the high-intensity focused ultrasound treatment apparatus 10 is the degree of change in the position of the treatment handpiece 210 or the first or second cartridge 310, 320 mounted on the treatment handpiece 210 during a procedure By detecting, it is possible to adjust the irradiation cycle or irradiation of the HIFU. For example, at least one position change sensor 218 capable of detecting the degree of position change of the procedure handpiece 210 may be provided inside the procedure handpiece 210.

Here, the position change sensor 218 is at least one of the movement, movement speed, movement acceleration, angular velocity, position, movement direction, inclination, and displacement of the surgical handpiece 210 or the first or second cartridge 310, 320 Any one or more can be detected.

As the position change sensor 218, a gyro sensor that detects the angular velocity of the surgical handpiece 210 may be used. Alternatively, as the position change sensor 218, an acceleration sensor that detects the acceleration of the surgical handpiece 210 may be used. The control unit 400 may receive the detection data of the position change detector 218 and change the irradiation period of the HIFU in proportion to the angular velocity or the acceleration. In one embodiment, the controller 400 may control at least one of an irradiation intensity, an irradiation period, an irradiation depth, and an irradiation angle of the high intensity focused ultrasound.

Accordingly, when the operator irradiates the HIFU while moving the procedure handpiece 210 on the skin tissue, the control unit 400 determines the moving speed of the procedure handpiece 210 so that the irradiation cycle of the HIFU is In order to satisfy the set irradiation cycle, it is possible to change the irradiation cycle of the HIFU. For example, when the position change of the surgical handpiece 210 is large, the irradiation period of the HIFU may be changed to shorten, and when the position change of the surgical handpiece 210 is small, the irradiation period of the HIFU may be changed to increase. Accordingly, the high-intensity focused ultrasound treatment apparatus 10 satisfies the interval between optimal thermal lesions preset in the skin tissue even when the operation speed of the surgical handpiece 210 is different for each user, and the thermal lesions ( 12) can be irradiated.

As described above, the high-intensity focused ultrasound treatment apparatus 10 according to an embodiment of the present invention includes at least one contact sensor S1 that detects whether the first cartridge 310 normally contacts the skin tissue during the procedure. , S2) and a control unit 400 for controlling the driving of the treatment transducer 314 of the first cartridge 310 by receiving a detection signal from the contact detectors S1 and S2. In this case, only when the first cartridge 310 is normally in close contact with the skin tissue to be treated during the procedure, the HIFU irradiation of the treatment transducer 314 may be controlled to be performed. Accordingly, the high-intensity focused ultrasound treatment apparatus according to the present invention determines whether or not the cartridge mounted on the treatment handpiece normally contacts the skin tissue, so that the high-intensity focused ultrasound is irradiated only when the cartridge is in normal contact. Can improve the safety of

The high-intensity focused ultrasound apparatus 10 according to an embodiment of the present invention includes a position change detector 218 that detects the degree of position change of the procedure handpiece 210 during a procedure, and a detection signal received from the position change detector 218 It may be provided with a control unit 400 for changing the HIFU irradiation cycle of the treatment transducer 314 in proportion to the degree of position change of the surgical handpiece 210. In this case, in the process of irradiating the HIFU while the operator moves the surgical handpiece 210 during the procedure, the irradiation cycle of the HIFU is changed in proportion to the angular velocity or acceleration change amount according to the position change of the surgical handpiece 210 By doing so, regardless of the degree of position change of the surgical handpiece 210, it is possible to irradiate the HIFU to the skin tissue at a preset HIFU interval. Accordingly, the high-intensity focused ultrasound treatment apparatus according to the present invention allows the HIFU irradiation period to be changed in proportion to the degree of change in the position of the cartridge or the procedure handpiece during the procedure, regardless of the amount of change in the angular velocity or acceleration of the cartridge or the procedure handpiece. , By allowing HIFU to be irradiated while maintaining a predetermined interval between thermal lesions on the skin tissue, the safety of a high intensity focused ultrasound procedure can be improved.

In addition, the high-intensity focused ultrasound treatment apparatus 10 according to an embodiment of the present invention includes the first cartridge 310 and the second cartridge 320 having conditions suitable for different types of treatments. ), the operator selects a cartridge capable of performing a desired procedure from among the first and second cartridges 310 and 320, and attaches it to the procedure handpiece 210 to perform the procedure. I can. In this case, compared to a high-intensity focused ultrasound medical device capable of only a single-purpose procedure, since various procedures can be performed only by replacing a cartridge as one device, a multipurpose ultrasonic medical device can be implemented. Accordingly, the high-intensity focused ultrasound treatment apparatus according to the present invention is provided with cartridges for various treatment purposes to be compatible with the treatment handpiece, and then a desired treatment purpose during a face lifting or skin tightening procedure or a reduction or removal procedure of the subcutaneous fat layer. By attaching the cartridge to the procedure handpiece and performing the procedure, it is possible to perform two or more high-intensity focused ultrasound procedures as a single device.

Subsequently, the cartridge set 300 according to an embodiment of the present invention will be described in detail. Here, the overlapping contents of the high-intensity focused ultrasound apparatus 10 described above may be omitted or simplified.

7 is a diagram for explaining the first and second cartridges 310 and 320 according to an embodiment of the present invention. More specifically, Figure 7 (a) is a view for explaining the operating conditions of the first cartridge 310 according to an embodiment of the present invention, Figure 7 (b) is a second cartridge according to an embodiment of the present invention ( It is a diagram for explaining the operation conditions of 320).

Referring to Figure 7 (a), the first cartridge 310 according to an embodiment of the present invention may be for a procedure to reduce or remove the subcutaneous fat layer. In one embodiment, the first cartridge 310 may be used when the thickness T1 of the subcutaneous fat layer 20 to be treated is 25.0mm or more. That is, the first cartridge 310 may be set in a condition that can be performed only when the thickness T1 of the subcutaneous fat layer 20 is 25.0 mm. In this case, the procedure patient may be highly obese. The first cartridge 310 is the upper and lower length (H1) of the HIFU lesion (lesion: 30) is adjusted to approximately 8.0mm to 12.0mm, the depth of irradiation from the skin surface of the HIFU is adjusted to approximately 11.0mm to 15.0mm. I can. If the upper and lower length H1 of the HIFU lesion 30 is less than about 8.0 mm, the reduction efficiency of the subcutaneous fat layer 20 may be lowered. Conversely, when the upper and lower length H1 of the HIFU lesion 30 exceeds approximately 12.0 mm, an HIFU lesion may be formed in a region outside the subcutaneous fat layer 20. In addition, when the irradiation depth is less than about 11.0mm or exceeds about 15.0mm, the HIFU lesion 30 may escape from the subcutaneous fat layer 20 during the procedure. Therefore, the treatment transducer 314 of the first cartridge 310 is approximately adjusted in the upper and lower length (H1) of the HIFU lesion 30, and the irradiation depth of the HIFU is adjusted to, the subcutaneous fat layer 20 Even if the procedure is performed when the thickness (T1) of) is 25.0mm or more, the risk of being operated on skin tissues other than the subcutaneous fat layer 20 can be alleviated.

In another embodiment, the first cartridge 310 may be used when the thickness T1 of the subcutaneous fat layer 20 to be treated is 7.0 mm or more and less than 25.0 mm. That is, the first cartridge 310 may be set to a condition capable of being performed when the thickness T1 of the subcutaneous fat layer 20 is at least 7.0 mm but is thinner than 25.0 mm. In this case, the procedure patient may be highly likely to be an initial obese patient. In this case, the first cartridge 310 has the upper and lower length H1 of the HIFU lesion (lesion: 30) adjusted to approximately 5.0 mm to 9.0 mm, while the irradiation depth of the HIFU from the skin surface is approximately 6.0 mm to 10.0 mm Can be adjusted. If the upper and lower length H1 of the HIFU lesion 30 is less than about 5.0 mm, the reduction efficiency of the subcutaneous fat layer 20 may be lowered. Conversely, when the upper and lower lengths H1 of each of the HIFU lesions 30 exceed approximately 9.0 mm, the HIFU lesions 30 may be formed in a region outside the subcutaneous fat layer 20. In addition, when the irradiation depth is less than about 6.0mm or exceeds about 10.0mm, the HIFU lesion 30 may escape the subcutaneous fat layer 20 during the procedure. Therefore, the treatment transducer 314 of the first cartridge 310 is approximately adjusted in the upper and lower length (H1) of the HIFU lesion 30, and the irradiation depth of the HIFU is adjusted to, the subcutaneous fat layer 20 Even if the procedure is performed when the thickness T1 of) is 7.0mm or more and less than 25.0mm, the risk of being applied to skin tissues other than the subcutaneous fat layer 20 can be alleviated.

Here, the treatment transducer 314 of the first cartridge 310 may perform a forward motion or a backward motion, that is, a linear reciprocating motion, so that a plurality of HIFU lesions 30 are generated. At this time, the interval between the HIFU lesions 30 is absent or less than 1.0 mm, so that the HIFU lesions 30 form a straight line or column shape without a break in the middle, while the subcutaneous fat layer 20 It can be pyrolyzed. However, when the HIFU lesions 30 overlap with each other, the pain felt by the patient to be treated may be large, so it may be ideal to irradiate the HIFU as close as possible under the condition that the HIFU lesions 30 do not overlap.

Referring to FIG. 7(b), the second cartridge 320 according to the embodiment of the present invention may be for a face lifting or skin tightening procedure, unlike the first cartridge 310 described above. In one embodiment, the skin tissue 40 to be treated by the second cartridge 320 may include a dermal layer or a fascia layer (SMAS layer) having a depth of about 1.5 mm to 4.5 mm from the skin surface. At this time, the second cartridge 320 may be adjusted so that the HIFU lesion (lesion: 50) is generated in a generally spherical, elliptical, or water droplet shape having a diameter of approximately 0.5mm to 1.5mm. If the diameter of the HIFU lesion 50 is less than about 0.5mm, the damage to the HIFU target tissue is very small, and it may be difficult to obtain an effect of face lifting or skin tightening through regeneration after intentional skin damage. Conversely, when the diameter of the HIFU lesion 50 exceeds 1.5mm, the HIFU lesion 50 may be formed in a region outside the skin tissue 40 to be treated. In addition, when the irradiation depth is less than about 1.5mm or exceeds about 4.5mm, the HIFU lesion 50 may deviate from the skin tissue 40 to be treated during the procedure. Therefore, it may be preferable that the treatment transducer 314 of the second cartridge 320 has a diameter of the HIFU lesion 50 approximately adjusted, and an irradiation depth of the HIFU adjusted to 1.5mm to 4.5. Most preferably, the irradiation depth of the HIFU lesion 50 may be any one selected from 1.5mm, 3.0mm, and 4.5mm, and the diameter of the HIFU lesion 50 may be approximately in or out.

Here, the treatment transducer 314 of the second cartridge 320 may generate a plurality of HIFU lesions 50 while performing a forward motion or a backward motion, that is, a linear reciprocating motion. At this time, the interval between the HIFU lesions 50 is approximately 0.5mm to less than 2.0mm, so that the HIFU lesions 50 are consequently spaced apart from each other, and a plurality of dots along the same line ) Can be adjusted to form. When the interval between the HIFU lesions 50 is less than 0.5mm, the HIFU lesions 50 are consequently connected to each other, resulting in a problem such as skin necrosis as an excessive thermal wound on the skin tissue. Conversely, when the interval between the HIFU lesions 50 exceeds 2.0mm, the interval between the HIFU lesions 50 is very large, and as a result, the face lifting or skin tightening effect may be significantly reduced.

Hereinafter, a process of performing a procedure using the high-intensity focused ultrasound procedure according to an embodiment of the present invention will be described in detail. Here, contents overlapping with the description of the high-intensity focused ultrasound apparatus 10 according to the embodiment of the present invention described above may be omitted or simplified.

8 is a flowchart schematically illustrating a procedure using a high-intensity focused ultrasound apparatus according to an embodiment of the present invention. 1 to 8, first, the selected cartridge may be mounted on the procedure handpiece 210 (S110). For example, the operator (not shown) may select the type of treatment to be performed on the subject (not shown). At this time, the type of treatment that can be selected may include at least one of a face lifting or skin tightening procedure, and a subcutaneous fat layer reduction or removal procedure. If the operator intends to perform a procedure to reduce or remove the subcutaneous fat layer, the operator may take into account the thickness of the subcutaneous fat layer, the depth of the subcutaneous fat layer, and other conditions of the subject to be treated. According to the first cartridge 310 can be selected. Here, in order to check the thickness of the subcutaneous fat layer, the operator directly recognizes the thickness of the subcutaneous fat layer by hand, or the subcutaneous fat layer imaged through an imaging device (not shown) such as an ultrasonic probe provided in the procedure handpiece 210 By checking, it is possible to calculate the exact thickness of the subcutaneous fat layer.

In one embodiment, when performing a procedure for reducing or removing the subcutaneous fat layer, the operator may select the cartridge 310 from the cartridge set 300 and mount it on the procedure handpiece 210. Alternatively, when the operator wishes to perform a face lifting or skin tightening procedure, the operator may select the second cartridge 320 from the cartridge set 300 and mount it on the procedure handpiece 210.

Next, it may be determined whether the cartridge is normally mounted on the surgical handpiece 210 (S120). For example, when the first cartridge 310 is selected from among the first or second cartridges 310 and 320 and mounted on the surgical handpiece 210, the electrode terminal 312c of the first cartridge 310 When the connectors 216 of the surgical handpiece 210 and the connectors 216 of the surgical handpiece 210 normally contact, it may be automatically determined that the cartridge 310 and the surgical handpiece 210 are normally mounted to each other. Conversely, when at least one of the electrode terminals 312c and the connectors 216 contacts abnormally, the control unit 400 determines that the contact between the cartridge 310 and the procedure handpiece 210 is defective. Thus, it is possible to suspend the investigation of the HIFU and generate an external mounting error alarm so that the operator can recognize such an abnormal mounting situation. As described above, the high-intensity focused ultrasound treatment apparatus 10 according to the present invention automatically detects whether the cartridge and the treatment handpiece 210 are normally installed, so that related information may be provided to the operator.

Next, it may be determined whether the cartridge has normal contact with the skin tissue and movement of the position has occurred (S130). More specifically, when the operator puts the cartridge mounted on the procedure handpiece 210 in close contact with the skin tissue for the procedure, the contact sensors S1 and S2 provided in the cartridge determine whether the cartridge has normally contacted the skin tissue. Can be detected. The controller 400 may determine whether or not the cartridge is in normal contact by determining a detection signal of the contact detectors S1 and S2. In addition, the controller 400 may determine whether the surgical handpiece 210 is moved. Here, if at least one of the normal contact of the cartridge with the skin tissue and the movement of the surgical handpiece 210 are not satisfied, the control unit 400 performs high intensity by the treatment transducer 314 The irradiation of focused ultrasound may be queued (S140).

When the normal contact of the cartridge with the skin tissue as described above and the movement of the procedure handpiece 210 are satisfied together, the procedure is performed while changing the irradiation cycle of the HIFU in proportion to the degree of change in the position of the procedure handpiece 210 Can be performed (S150). More specifically, when a surgeon moves the procedure handpiece 210 for a procedure, the control unit 400 receives a detection signal from the position change sensor 218 provided in the procedure handpiece 210 and receives the The degree of change in the position of the surgical handpiece 210 may be determined. In this case, the control unit 400 may determine the degree of change in the position of the surgical handpiece 210 by detecting a change in angular velocity or an acceleration of the surgical handpiece 210. The control unit 400 determines the degree of position change of the procedure handpiece 210, based on the degree of position change of the procedure handpiece 210, the HIFU irradiation cycle of the treatment transducer 314 is the The driver 217 may be controlled to satisfy the reference interval of the thermal lesions 12.

As described above, it is possible to detect whether or not the cartridge is in normal contact with the skin tissue so that HIFU irradiation can be performed only when the cartridge is in normal contact, so the safety of the procedure can be improved.

In addition, it is possible to change the HIFU irradiation cycle of the treatment transducer 314 in proportion to the position change degree after detecting the degree of position change of the procedure handpiece 210 during the procedure. In this case, in the process of irradiating the HIFU while the operator moves the surgical handpiece 210 during the procedure, the irradiation cycle of the HIFU is changed in proportion to the angular velocity or acceleration change amount according to the position change of the surgical handpiece 210 By doing so, irrespective of the degree of change in the position of the surgical handpiece 210, the HIFU can be irradiated to the skin tissue at a preset HIFU interval, thereby improving the safety of the procedure.

In addition, after selecting the type of treatment for the subject to be treated, the first cartridge 310 or the second cartridge 320 capable of a desired treatment is selected from the cartridge set 300, and then mounted on the treatment handpiece 210. It can be performed. Accordingly, various types of treatments are performed by installing cartridges having various treatment conditions to the treatment handpiece to be compatible with the treatment handpiece, and then installing cartridges having conditions suitable for the treatment type and the obesity state or treatment site of the treatment subject to the treatment handpiece. Can be performed by optimizing each patient or site.
