Hereinafter, the complex surgical device according to the present invention will be described in detail with reference to the attached drawings.

As shown in FIG. 1, the complex surgical device according to the first embodiment of the present invention includes a main body 10 and a handpiece 20 connected to the main body 10 through a signal transmission unit 18. do.

The complex surgical device may further include a cooling unit 42 to prevent the skin of the recipient from being damaged by heat generated by the laser during a procedure using a laser.

In addition, the handpiece 20 is a device that performs fat decomposition treatment by opposing the skin tissue of the treatment subject during the procedure. The handpiece 20 is fixedly attached to the body of the subject through the fixation unit 50. You can. The fixing unit 50 may be used to fix the handpiece 20 on the skin tissue to be treated during the procedure. The fixing unit 50 will be described in detail later with reference to FIG. 5 .

The main body 10 may be provided with a manipulation unit 12 that includes a plurality of operation buttons for the operator to operate the procedure and a display unit 14 for displaying procedure information. Additionally, the main body 10 may be provided with a control unit 16 to perform operations based on the operator's instructions input through the operation unit 12 and to receive and process information from various sensors.

The cooling unit 42 may be installed inside the main body 10 and is configured to cool the refrigerant and supply it to the handpiece 20. Various types of liquids or gases can be used as refrigerants.

The refrigerant is supplied from the cooling unit 42 to the handpiece 20 to cool the treatment area of the patient and then returns to the cooling unit 42 inside the main body 10. For this, the refrigerant can circulate. A refrigerant circulation path 44 may be included. The refrigerant circulation path 44 can be connected between the main body 10 and the handpiece 20 through the signal transmission unit 18 as shown in FIG. 1. If necessary, a separate connection line for the refrigerant circulation path 44 may be extended and installed between the main body 10 and the handpiece 20.

Although not shown, wheels for easy movement, a stand for holding the handpiece 20, etc. may be installed on the main body 10.

The handpiece 20 can be electrically connected to the main body 10 by the signal transmission unit 18. A plurality of handpieces 20 may be provided. As an example, one complex surgical device may be equipped with four hand pieces and configured to perform the procedure by being disposed along the circumference of the abdomen of the patient during the procedure.

The handpiece 20 includes a laser diode module (hereinafter referred to as 'LD module') 22 for generating a laser beam, and a light emitting diode module (hereinafter referred to as 'LED module') that emits light for skin care purposes. may include) (24).

The LD module 22 generates a laser beam to decompose fat by irradiating a laser to fat cells distributed inside the skin. The wavelength and output of the laser generated from the LD module 22, the type of laser diode, etc. do not limit the present invention, and lasers of various specifications can be used as long as they can achieve a lipolysis effect.

The laser can heat and break down cellulite and fatty tissue located under the dermal layer. For example, since the laser has a higher straightness than other light sources, it is known to penetrate into cellulite and fat tissue within the skin layer. Additionally, red lasers with a wavelength of approximately 1060 nm to 1070 nm are known to decompose cellulite and fatty tissue. Therefore, the fat decomposition device according to the present invention can decompose fat by penetrating a laser into the skin tissue to be treated through the handpiece 20.

The principle of decomposing fat tissue using a laser is roughly known as follows. When a laser is fired at the subcutaneous fat layer, it is absorbed by atomic groups (i.e., chromophores) that selectively absorb light of a specific wavelength, and this energy generates heat. The generated heat causes thermal damage to fat cells, collagen, and microcirculation vessels. I do it. The heat delivered to the fat cell creates a hole in the cell membrane the same size as the diameter of the optical fiber, causing the fat inside the fat cell to come out of the cell. The fat flows out and the remaining fat cells are broken down.

In addition, lasers can be divided into high-power lasers and low-power lasers depending on the size of the output. When using high-power lasers, it is necessary to use a skin cooling means to prevent damage to skin tissue due to heat generated from the equipment itself. . That is, the handpiece 20 may be cooled by a cooling means so that the handpiece 20 in contact with the skin does not overheat during the procedure.

It is appropriate for the laser to be used to have a penetration depth equivalent to or longer than the depth of the subcutaneous tissue at the point where the subcutaneous tissue in the area where the treatment is performed is thickest. The wavelength of the laser that meets the requirement of being able to penetrate into the skin tissue to heat the treatment area can be selected, for example, within the range of approximately 800 nm to 1200 nm. For example, considering tissue penetration and relatively low absorption by melanin, the main chromatophore of the skin, and moisture, a red laser with a wavelength of approximately 1060 nm to 1065 nm may be selected.

In the present invention, in addition to the laser in the wavelength range of approximately 800 nm to 1200 nm mentioned above, for fat decomposition, a laser in the 1.7㎛ wavelength range, which is known to have a relatively high light absorption rate by fat components, can be used, and the wavelength of the laser used is determined by the present invention. does not limit

The laser can be stopped at regular time intervals during the procedure so that the temperature of the treatment area can be maintained at a temperature that allows fat decomposition without damaging the skin. Alternatively, the laser may be operated and stopped alternately based on the temperature detection value of the skin or handpiece detected by the temperature sensor.

Above, a cooling method was described in which a cooling unit is installed in the main body to prevent skin damage due to heat generation from the laser, and coolant is circulated from this cooling unit to the handpiece through a refrigerant circulation path. However, the present invention is limited to this cooling method. It doesn't work.

According to another example, the complex surgical device may include at least one of a handpiece cooling unit that cools the handpiece and a skin cooling unit that cools the skin of a body part where the procedure is performed.

The handpiece cooling unit can cool the heat generated by the handpiece 20 from laser generation using a thermoelectric cooling (TEC) method. The thermoelectric cooling element used for TEC-type cooling can be of any specification as long as it is mounted on the handpiece and can cool the heat generated by the laser.

The skin cooling unit may be configured to spray skin cooling gas onto the skin. The skin cooling gas sprayed onto the skin may be atmospheric air or air cooled by a known refrigerant refrigeration cycle. In order to spray skin cooling gas onto the skin of the body part where the procedure is being performed, a hole through which gas can flow may be formed on the glass surface of the front of the handpiece, such as the sapphire crystal 36 (see FIGS. 2 and 3). there is. A fan (not shown) may be installed inside the handpiece 20 to spray gas. Alternatively, after installing a fan (not shown) inside the main body 10, a flexible pipe capable of flowing gas pressurized by the fan is embedded across the signal transmission unit 18 and the handpiece 20. , It may be configured to spray the gas onto the skin.

The LED module 24 can be used to promote skin cell regeneration by irradiating light to the outside of the skin, that is, the epidermis. The light generated by the LED module 24 can exert effects on skin elasticity and whitening, and can improve skin trouble symptoms such as acne, freckles, and freckles. As with the LD module, the characteristics and types of the LED module used do not limit the present invention.

Light irradiation by the LED module 24 may be performed before, after, or together with the laser irradiation by the LD module 22. Alternatively, the operation of the LED module and the operation of the LD module may be performed alternately. Alternatively, the procedure may be performed using only the LED module without operating the LD module, or conversely, the procedure may be performed using only the LD module without operating the LED module.

In addition, the handpiece 20 includes a temperature sensor 26 that detects temperature to check whether the skin tissue is overheated due to heat generated by the laser, and a temperature sensor 26 that checks whether the handpiece body is installed in accurate contact with the skin of the recipient. It may include a contact sensor (28). Measurement data measured by the temperature sensor 26 and the contact sensor 28 can be transmitted to the control unit 16 built into the main body 10, and the control unit 16 analyzes the measurement data to control the handpiece 20. ), it is possible to determine whether the operation is within a preset temperature range or whether the treatment is being performed in normal contact with the skin tissue to be treated.

An indicator light 30 can be installed on the outside of the handpiece 20 to indicate whether the operation of the handpiece is good or bad, and the operator can check whether the procedure is being performed safely and accurately through this indicator light 30. You can.

Figures 2, 3, and 4 show a schematic perspective view, exploded perspective view, and plan view of the handpiece included in the complex surgical device according to the first embodiment of the present invention. As shown in FIGS. 2 to 4, the handpiece 20 has a substantially rectangular parallelepiped shape and includes a handpiece body 32 connected to the signal transmission unit 18, and a handpiece body 32 to be mounted on the handpiece body 32. It may include a cover 34 that can be used. An opening through which a laser beam can be irradiated may be formed in the cover 34, and a transparent protective window with high laser beam transmittance may be mounted on this opening. As a protective window, for example, a transparent sapphire crystal 36 can be used. Using sapphire crystal, the transmittance of the laser beam can be increased and the irradiation range can be expanded.

A temperature sensor 26 may be installed inside the cover 34. 2 and 3 show that the temperature sensor 26 is installed to be exposed to the outside of the cover 34, but as shown in FIG. 4, the temperature sensor 26 may be installed not to be exposed to the outside. The temperature sensor 26 is used to check whether the treatment area maintains a preset temperature within the error range during the procedure. The temperature sensor 26 may measure the temperature of the handpiece 20 itself or may measure the skin temperature of the area where the treatment is being performed.

Additionally, the contact sensor 28 may be disposed on both edges of the cover 34 in the longitudinal direction. The contact sensor 28 can detect whether the handpiece 20 is in close contact with the body part where the procedure is to be performed. For accurate detection of adhesion, multiple contact sensors 28 may be used.

A reflector 38 is formed on the inner surface of the handpiece body 32 to increase the reflection efficiency of the laser beam. The reflector 38 may be formed to be inclined so that the internal space expands as it moves from the signal transmission unit 18 toward the cover 34. The inclination angle of the reflector 38 may be constant throughout the entire reflector. The reflector 38 may be made of copper material, for example.

The LD module 22 may be disposed between the reflector 38 and the signal transmission unit 18, and as described above, the wavelength and output of the laser generated from the LD module 22, the type of laser diode, etc. are determined according to the present invention. It is not limited, and lasers of various specifications can be used as long as they can achieve a fat decomposition effect. A laser irradiation unit 40 may be disposed between the LD module 22 and the reflector 38 to spread the laser beam. The laser irradiation unit 40 may perform the function of refracting the incident laser beam and spreading it to irradiate the entire area corresponding to the opening formed in the cover of the handpiece. For example, the laser irradiation unit may be made of a transparent plate with a very fine concavo-convex structure formed on one surface, but is not limited to this.

A plurality of LED modules 24 can be arranged on the reflector 38, and as described above, the characteristics and types of the LED module 24 do not limit the present invention, and can be used in various specifications as long as skin care effects can be achieved. LEDs may be used.

Referring to FIG. 4, the LED modules 24 arranged on the reflector 38 may be positioned so as to be evenly distributed over the entire area of the reflector 38 when viewed from a plan view. The number and location of LED modules 24 shown in the drawing are only examples and do not limit the present invention.

A refrigerant circulation path 44 may be installed inside the signal transmission unit 18 to circulate the refrigerant between the main body 10 and the handpiece 20. The refrigerant circulation path 44 installed inside the signal transmission unit 18 may be made of a flexible pipe. The refrigerant circulation path 44 may be formed to connect the main body 10 and the handpiece 20 separately from the signal transmission unit 18.

In the handpiece 20, the refrigerant circulation path 44 through which the refrigerant from the cooling unit 42 circulates may be arranged close to the cover 34 inside the handpiece body 32. For example, as illustrated in FIG. 4 , the refrigerant circuit 44 may be arranged to surround the sapphire crystal 36 . If the heat generated by the laser beam can be appropriately suppressed to prevent damage to the skin of the person being treated, the size, shape, arrangement, etc. of the refrigerant circulation path 44 can be modified in various ways other than those shown.

Figure 5 is a schematic perspective view of a fixing unit that is included in the complex surgical device according to the first embodiment of the present invention and fixes the position of the handpiece, and Figure 6 is a view showing various embodiments of the fixing unit shown in Figure 5. am.

Referring to FIG. 5, the handpiece 20 may be used with a fixation unit 50 so that it can be maintained in a predetermined position with respect to the body of the person being treated while the procedure is in progress.

The fixing unit 50 may include a frame 52 on which the handpiece 20 can be mounted, and a belt 58 that can fixedly position the frame 52 on a specific part of the patient's body. .

The frame 52 has a central portion so as not to block the light (laser beam from the LD module or light from the LED module) irradiated through the sapphire crystal 36 of the handpiece 20 from reaching the body. It may have an open, approximately square frame shape. A pair of coupling portions 54 are protruding from the frame 52, and the coupling portions 54 may have a structure for detachably coupling the handpiece 20. For example, the coupling portion 54 has a concave groove or hole, and a protrusion is formed on the hand piece 20, and the hand piece 20 is detachable from the frame 52 through coupling between them. It may be configured to be mounted. The shape of the coupling portion 54 can be modified in various ways, and any configuration can be used as long as the handpiece can be detachably coupled.

When the handpiece 20 is used with the fixing unit 50, the contact sensor 28 installed on the handpiece 20 may be configured to detect the state in which the handpiece 20 is in close contact with the frame 52. there is.

A belt 58 may be connected to the frame 52, and for this purpose, belt connection portions 56 may be formed on both sides of the frame 52. The belt 58 may be made of an elastic material and may be configured to adjust its length.

Referring to FIG. 6, the frame 52 of the fixing unit 50 may have various shapes. Figure 6(a) illustrates a frame 52a on which four handpieces can be mounted in parallel. Figure 6(b) illustrates a frame 52b on which three handpieces can be mounted in parallel. Figure 6(c) illustrates a frame 52c on which two handpieces can be mounted in parallel. And, Figure 6(d) illustrates a frame 52d on which one handpiece can be mounted.

The frames shown in FIG. 6 are all examples only, and various types of frames may be used as needed.

FIG. 7 shows various examples of arrangement of the handpiece for the operator during a procedure using a complex surgical device. Figure 7 (a) shows an example of the arrangement of a handpiece when performing a procedure on the lower abdomen of a person being treated using the frame 52a shown in Figure 6 (a). Figure 7(b) shows an example of the handpiece arrangement when performing a procedure on the lower abdomen of a person being treated using the frame 52b shown in Figure 6(b). Figure 7 (c) shows a handpiece for performing a procedure on the abdomen of a patient using the frame 52b shown in Figure 6 (b) and the frame 52d shown in Figure 6 (d) together. An example of arrangement is shown. Figure 7(d) shows a handpiece for performing a procedure on the abdomen of a person being treated using the frame 52c shown in Figure 6(c) and the frame 52d shown in Figure 6(d) together. An example of arrangement is shown. FIG. 7(e) shows an example of the arrangement of the handpiece when performing a procedure on the left and right sides of the lower abdomen of the person being treated using two frames 52c shown in FIG. 6(c). And, Figure 7 (f) shows an example of the arrangement of the handpiece when performing a procedure on the side of the patient using the frame 52c shown in Figure 6 (c).

What is shown in FIG. 7 is only an example, and the procedure can be performed on various body parts other than the abdomen or side of the recipient. Additionally, the procedure can be performed by arranging the handpiece in a form not shown using various types of frames.

The complex surgical device according to the first embodiment of the present invention configured as described above can operate as follows.

Referring again to FIG. 1, the operator sets the type of treatment suitable for the patient, the treatment time, the number of handpieces to be used, etc. through the operation unit 12 installed on the main body 10. At this time, the handpiece to be used for the procedure may be attached to the patient through a fixation unit.

The control unit 16 can check whether the handpiece 20 to be used is maintained in the correct position based on detection information from the contact sensor 28 installed on the handpiece 20. The control unit 16 can notify the operator of whether the handpiece 20 is in the correct position by displaying it on at least one of the indicator light 30 installed on the handpiece 20 and the display unit 14 installed on the main body 10. .

Upon confirming that the handpiece 20 is maintained in the correct position, the control unit 16 controls the operation of the handpiece 20 according to the setting value input by the operation unit 12. For example, if the heating temperature for the fat tissue under the dermal layer is set to about 42 to 47, the LD module 22 is operated to radiate a laser beam to the treatment area, and the LED module 24 is also operated to illuminate the treatment area. Skin beauty treatment can be started by irradiating light.

While the temperature of the treatment area reaches the set temperature and lipolysis treatment is being performed, the LED module 24 may be stopped, or the LED module 24 may be operated simultaneously with irradiation of the laser beam. If necessary, only the LED module 24 can be operated without operating the LD module 22.

While the procedure is in progress, the control unit 16 checks whether it is operating normally through the temperature sensor 26 and the contact sensor 28. When the temperature of the part of the handpiece 20 adjacent to the treatment area measured by the temperature sensor 26, for example, the cover 34, rises beyond the set range, the control unit 16 temporarily suspends the operation of the LD module 22. It can be stopped. At this time, the control unit 16 can display this information on the display unit 14 so that the equipment user can see it. In addition, when the temperature of the handpiece 20 adjacent to the treatment area measured by the temperature sensor 26 falls below the set range, the control unit 16 automatically turns on the LD module 22 again. It can be restarted, or information about whether restart is possible can be displayed on the display unit 14 so that the user can operate it.

In the event that the temperature of the treatment area continues to rise above the set range or the handpiece 20 deviates from its normal position, the control unit 16 displays the indicator light 30 installed on the handpiece 20 and the main body 10. An abnormality is displayed on at least one of the installed display units 14 and the operator is notified. When necessary, the control unit 16 can stop the operation of the LD module 22 even without operator intervention.

When the set time elapses, the control unit 16 stops operating the handpiece and displays on the display unit 14 that the procedure is complete.

When performing a procedure using multiple handpieces, the operating time of each handpiece may be the same or may be set differently for each handpiece.

Figure 8 shows a schematic perspective view of the handpiece included in the complex surgical device according to the second embodiment of the present invention. The complex surgical device according to the second embodiment of the present invention includes a main body and a handpiece, similar to the complex surgical device according to the first embodiment of the present invention shown in FIG. 1, but the main body is not shown in FIG. 8 for convenience. , the main body and signal transmission part are the same as those in the first embodiment, so description thereof is omitted. Hereinafter, the complex surgical device according to the second embodiment will be described, focusing on parts that are different from the first embodiment.

As shown in Figure 8, the handpiece 120 according to the second embodiment, compared to the handpiece 20 shown in Figures 2 to 4, has an LD module 22 for lipolysis treatment and a skin Although it is the same in that it includes an LED module 24 for cosmetic procedures, it differs in that it has a roughly hemispherical handpiece body 132.

Like the first embodiment, one LD module 22 is located at the center of the reflector 138, and multiple LED modules 24 may be arranged on the reflector 138. A plurality of LED modules 24 may be arranged to be evenly distributed on the reflector 138.

In addition, in the handpiece 120 according to the second embodiment, the reflector 138 may be rotatably mounted with respect to the handpiece body 132, and in this case, the LED module 24 includes the rotating reflector 138 and Can be rotated together. As the LED module 24 is installed, some areas of the reflector 138 cannot reflect the laser beam from the LD module 22, so there is a risk of shading even if it is only a small part. However, if the reflector 138 rotates, , concerns about shading can be eliminated.

Although not shown in FIG. 8, the temperature sensor and contact sensor installed on the handpiece may be mounted at a predetermined position on the handpiece body or cover. In addition, the handpiece 120 according to the second embodiment can also be used with a fixing unit (not shown), and in this case, the frame of the fixing unit (not shown) may be circular to correspond to the shape of the handpiece 120. there is.

According to the present invention, the handpieces provided in one complex surgical device do not all need to have the same shape, and one complex surgical device includes the square handpiece 20 according to the first embodiment and the handpiece 20 of the second embodiment. It can be modified to be provided with a hemispherical handpiece 120 according to the present invention.

In Figure 8, the reflector 138 formed on the inner surface of the handpiece body 132 according to the second embodiment is shown to have the same shape as the reflector 38 of the handpiece 20 shown in Figures 2 to 4. However, the shape of the reflector may be modified to be hemispherical to correspond to the hemispherical handpiece body 132.

Figure 9 shows a schematic perspective view of a fixing unit included in the complex surgical device according to the third embodiment of the present invention. The complex surgical device according to the third embodiment of the present invention includes a main body and a handpiece, similar to the complex surgical device according to the first embodiment of the present invention shown in FIG. 1, but the main body is not shown in FIG. 9 for convenience. , the main body and signal transmission part are the same as those in the first embodiment, so description thereof is omitted. Hereinafter, the complex surgical device according to the third embodiment will be described, focusing on parts that are different from the first embodiment.

As shown in FIG. 9, in the complex surgical device according to the third embodiment, the refrigerant circulation path 244 through which the refrigerant supplied from the cooling unit flows is not the hand piece 220, but the frame of the fixing unit 250 ( 252), it is different from the complex surgical device according to the first embodiment.

9 illustrates a frame in which two hand pieces 220 can be detachably mounted, and a refrigerant circulation path 244 is formed around each opening inside the frame 252. The location of the refrigerant circulation path 244 is not limited to that shown.

The complex surgical device according to the third embodiment further includes a separate refrigerant flow path (not shown) connecting the main body and the frame 352 to supply refrigerant to the refrigerant circulation path 244 built into the frame 252. Alternatively, a separate refrigerant flow path (not shown) connecting the handpiece 320 and the frame 352 may be further included.

According to the third embodiment, the refrigerant circulation path 244 is installed in the frame 252 of the fixing unit 250 rather than the handpiece 220, so the handpiece 220 according to the third embodiment has the refrigerant circulation path 244. It may be configured the same as the handpiece 20 according to the first embodiment except that is removed.

The present invention is not limited to the embodiments described above, and it is obvious to those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations should be considered to fall within the scope of the claims of the present invention.
