Description

PROCEDURE DEVICE USING LASER AND PROCEDURE METHOD USING THE DEVICE

The present invention relates to a treatment device using a laser and a treatment method using the same.

Due to the abundance of food and westernization of eating habits, the number of people classified as obese or overweight is gradually increasing. On the other hand, as interest in health increases, the number of people trying to lose weight to avoid the risk of various diseases caused by obesity or overweight is also increasing.

According to the World Health Organization (WHO) Asia-Pacific Perspective, for adults, a body mass index (BMI) of 23 kg/m2 or higher is considered overweight, and 25 kg/m2 or higher is considered obesity. According to the treatment guidelines of the Korean Endocrine Society, obesity is defined as 25 kg/m2 or higher for Koreans, and it is recommended that treatment should begin at 23 kg/m2 or higher in cases where there are accompanying obesity-related diseases.

Since most cases of obesity or overweight are due to increased body fat, an appropriate diet should come first in order to lose weight, but for adult patients with a BMI of 40㎏/㎡ or higher or 35㎏/㎡ or higher and a disease related to obesity, treatment through bariatric surgery is recommended.

However, since surgical obesity surgery inevitably involves bleeding and pain, continuous research and development on non-surgical obesity surgery is necessary.

Among the methods for reducing fat, there is a method of using a laser to heat obese fat cells to break down fat as a non-surgical and non-invasive method. As an example of a fat-breaking device that breaks down fat by this method, a device is proposed that transmits laser generated by a laser generating means installed in the main body to a handpiece and performs a fat-breaking procedure by bringing the handpiece into contact with the body of the person receiving the procedure.

However, since these devices simply irradiate the body of the recipient with lasers to perform lipolysis, there is a problem in that in order to perform other procedures besides laser lipolysis, not only is a different type of device required, but the time and cost required for the procedure also increase.

Republic of Korea Patent Publication No. 10-2013-0005126 (January 15, 2013)

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

As illustrated in FIG. 1, the composite 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).

The complex treatment device may further include a cooling unit (42) to prevent the skin of the subject from being damaged by heat generated by the laser during treatment using the laser.

In addition, the handpiece (20) is a device that performs a fat decomposition treatment while facing the skin tissue of the subject of the treatment during the treatment, and the handpiece (20) can be fixedly attached to the body of the subject of the treatment through a fixing unit (50). The fixing unit (50) may be for fixing the handpiece (20) on the skin tissue of the subject of the treatment during the treatment. The fixing unit (50) will be described in detail later with reference to FIG. 5.

The main body (10) may be equipped with an operation unit (12) that may be composed of a number of operation buttons for the operator to operate the procedure, and a display unit (14) for displaying procedure information. In addition, the main body (10) may be equipped with a control unit (16) for performing a procedure based on the operator's instructions input by the operation unit (12) and receiving and processing information from various sensors.

The cooling unit (42) can 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 the refrigerant.

The refrigerant may be supplied from the cooling unit (42) to the handpiece (20) to cool the treatment area of the subject and then return to the cooling unit (42) inside the main body (10). For this purpose, a refrigerant circulation path (44) through which the refrigerant may circulate may be included. The refrigerant circulation path (44) may connect the main body (10) and the handpiece (20) via a 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 included, the main body (10) may be equipped with wheels for easy movement, a stand for holding the handpiece (20), etc.

The handpiece (20) can be electrically connected and connected to the main body (10) by the signal transmission unit (18). A plurality of handpieces (20) can be provided. As an example, one complex treatment device can be provided with four handpieces, and can be configured to be arranged along the abdominal circumference of the subject of the treatment to perform the treatment.

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

The LD module (22) generates a laser so that fat can be decomposed by irradiating the 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 the fat decomposition effect can be achieved.

The laser can heat and decompose cellulite and adipose tissue located under the dermis layer. For example, since the laser has a high straightness compared to other light sources, it is known to penetrate cellulite and adipose tissue within the skin layer. In addition, a red laser with a wavelength of approximately 1060 nm to 1070 nm is known to decompose cellulite and adipose tissue. Therefore, the fat decomposition device according to the present invention can decompose fat by penetrating the laser into the target skin tissue through the handpiece (20).

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

In addition, lasers can be classified into high-power lasers and low-power lasers depending on the size of the output. When using a high-power laser, it is necessary to use a skin cooling means together to prevent damage to skin tissue caused by heat generated from the equipment itself. That is, in order to prevent the handpiece (20) that comes into contact with the skin during the procedure from overheating, cooling of the handpiece (20) by a cooling means can be performed together.

The laser used is preferably one having a penetration depth equivalent to or longer than the depth of the subcutaneous tissue at the thickest point in the area where the treatment is performed. The wavelength of the laser that satisfies the requirement of being able to penetrate into the skin tissue so as to heat the treatment area can be selected, for example, within the range of about 800 nm to 1200 nm. For example, considering tissue penetrability and relatively low absorption by melanin, which is the main pigment of the skin, and water, a red series laser having a wavelength of about 1060 nm to 1065 nm can be selected.

In addition to the laser having a wavelength of approximately 800 nm to 1200 nm as mentioned above for fat decomposition, the present invention may also use a laser having a wavelength of 1.7 μm, which is known to have a relatively high light absorption rate by fat components, and the wavelength of the laser used is not limited to the present invention.

The laser may be stopped at regular intervals during the procedure so that the temperature of the treatment area can be maintained at a temperature that allows fat to be broken down 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 caused by heat generation from a laser, and a refrigerant is circulated from the cooling unit to the handpiece through a refrigerant circulation path. However, the present invention is not limited to this cooling method.

According to another example, the composite treatment device may include at least one of a handpiece cooling unit that performs cooling for the handpiece and a skin cooling unit that performs cooling for the skin of the body part where the treatment is performed.

The handpiece cooling unit can cool the heat generated from the handpiece (20) by laser generation using the TEC (Thermoelectric Cooling) method. Any type of thermoelectric cooling element used for TEC-type cooling can be used 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 a skin cooling gas onto the skin. The skin cooling gas sprayed onto the skin may be air in the atmosphere or air cooled by a known refrigerant cooling cycle. In order to spray the skin cooling gas onto the skin of the body part where the procedure is being performed, a glass surface on the front side of the handpiece, for example, a sapphire crystal (36) (see FIGS. 2 and 3), may have holes formed through which the gas can flow. A fan (not shown) may be installed inside the handpiece (20) to spray the gas. Alternatively, after installing a fan (not shown) inside the main body (10), a flexible pipe capable of flowing the gas pressurized by the fan may be embedded across the signal transmission unit (18) and the handpiece (20), thereby spraying the gas onto the skin.

The LED module (24) can be used to promote skin cell regeneration by irradiating light to the outer part of the skin, i.e., the epidermis. The light generated by the LED module (24) can have effects on skin elasticity and whitening, and can improve skin trouble symptoms such as acne, blemishes, and freckles. As with the LD module, the characteristics, type, etc. of the LED module used do not limit the present invention.

The light irradiation by the LED module (24) can be performed before or after the laser irradiation by the LD module (22), or together with the laser irradiation. Alternatively, the operation of the LED module and the operation of the LD module can be performed alternately. Alternatively, the treatment can be performed using only the LED module without operating the LD module, or conversely, the treatment can be performed using only the LD module without operating the LED module.

In addition, the handpiece (20) may include a temperature sensor (26) that detects temperature to check whether skin tissue is overheated due to heat generated by the laser, and a contact sensor (28) that checks whether the handpiece body is installed in close contact with the skin of the subject. Measurement data measured by the temperature sensor (26) and the contact sensor (28) may be transmitted to the control unit (16) built into the main body (10), and the control unit (16) may analyze the measurement data to determine whether the operation of the handpiece (20) is performed within a preset temperature range or whether the handpiece is performing the procedure by normally contacting the skin tissue to be treated.

An indicator light (30) that can indicate whether the handpiece is operating well or poorly can be installed on the outside of the handpiece (20), so that the practitioner can check whether the procedure is being performed safely and accurately through this indicator light (30).

FIGS. 2, 3 and 4 illustrate a schematic perspective view, an exploded perspective view and a plan view of a handpiece included in a composite surgical device according to the first embodiment of the present invention. As illustrated in FIGS. 2 to 4, the handpiece (20) may include a handpiece body (32) having a substantially rectangular parallelepiped shape and connected to a signal transmission unit (18), and a cover (34) that may be mounted on the handpiece body (32). An opening may be formed in the cover (34) for irradiating a laser beam, and a transparent protective window having high laser beam transmittance may be mounted on the opening. As the protective window, for example, a transparent sapphire crystal (36) may be used. Using a sapphire crystal can increase the laser beam transmittance and expand the irradiation range.

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

In addition, the contact sensors (28) can be placed on both longitudinal edges of the cover (34). The contact sensors (28) can detect whether the handpiece (20) is in contact with the body part where the procedure is to be performed. In order to accurately detect whether there is contact, a plurality of contact sensors (28) can 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 inner space becomes wider as it goes from the signal transmission unit (18) toward the cover (34). The inclination angle of the reflector (38) may be constant over the entire reflector. The reflector (38) may be made of, for example, copper.

An LD module (22) may be placed 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., do not limit the present invention, and lasers of various specifications may be used as long as they can achieve a fat decomposition effect. A laser irradiation unit (40) for diffusing the laser beam may be placed between the LD module (22) and the reflector (38). The laser irradiation unit (40) may perform a function of refracting the incident laser beam and diffusing it so that it is irradiated over the entire area corresponding to the opening formed in the cover of the handpiece. For example, the laser irradiation unit may be formed of a transparent plate having a very fine uneven structure formed on one surface, but is not limited thereto.

A plurality of LED modules (24) can be arranged on the reflector (38), and as described above, the characteristics and types of the LED modules (24) do not limit the present invention, and LEDs of various specifications can be used as long as they can achieve a skin beauty effect.

Referring to FIG. 4, the LED modules (24) arranged on the reflector (38) can be positioned so as to be evenly distributed over the entire area of the reflector (38) when viewed from a plane. The number and positions of the LED modules (24) shown in the drawing are merely examples and do not limit the present invention.

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

In the handpiece (20), a coolant circulation path (44) through which coolant 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 coolant circulation path (44) may be arranged to surround a sapphire crystal (36). The size, shape, arrangement, etc. of the coolant circulation path (44) may be modified in various ways other than those illustrated, as long as heat generation due to the laser beam can be appropriately suppressed to prevent damage to the skin of the subject.

FIG. 5 is a schematic perspective view of a fixing unit that is included in a composite surgical device according to the first embodiment of the present invention and fixes the position of a handpiece, and FIG. 6 is a drawing showing various embodiments of the fixing unit illustrated in FIG. 5.

Referring to FIG. 5, the handpiece (20) can be used together with a fixing unit (50) so that it can be maintained in a set position with respect to the body of the subject while the procedure is in progress.

The fixed unit (50) may include a frame (52) on which a handpiece (20) can be mounted, and a belt (58) that can fixally position the frame (52) on a specific part of the body of the subject.

The frame (52) may have a roughly square frame shape with an open center so as not to prevent light (a laser beam from an LD module or light from an LED module) irradiated through the sapphire crystal (36) of the handpiece (20) from reaching the body. A pair of coupling parts (54) may be formed protrudingly on the frame (52), and the coupling parts (54) may have a structure for detachably coupling the handpiece (20). For example, the coupling parts (54) may have a concave groove or hole, while the handpiece (20) may have a protrusion, and the handpiece (20) may be configured to be detachably mounted on the frame (52) through coupling therebetween. The shape of the coupling parts (54) may be variously modified, and any configuration may be used as long as the handpiece can be detachably coupled.

When the handpiece (20) is used with a fixing unit (50), the contact sensor (28) installed in the handpiece (20) can be configured to detect a state in which the handpiece (20) is in close contact with the frame (52).

A belt (58) may be connected to the frame (52), and for this purpose, belt connecting 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 be adjustable in length.

Referring to FIG. 6, the frame (52) of the fixed unit (50) may have various shapes. FIG. 6 (a) illustrates a frame (52a) capable of mounting four handpieces in parallel. FIG. 6 (b) illustrates a frame (52b) capable of mounting three handpieces in parallel. FIG. 6 (c) illustrates a frame (52c) capable of mounting two handpieces in parallel. And FIG. 6 (d) illustrates a frame (52d) capable of mounting one handpiece.

All frames shown in Fig. 6 are only examples, and various types of frames may be used as needed.

FIG. 7 illustrates various examples of handpiece placement with respect to a subject during a procedure using a composite procedure device. FIG. 7 (a) illustrates an example of handpiece placement when performing a procedure on the lower abdomen of a subject using the frame (52a) illustrated in FIG. 6 (a). FIG. 7 (b) illustrates an example of handpiece placement when performing a procedure on the lower abdomen of a subject using the frame (52b) illustrated in FIG. 6 (b). FIG. 7 (c) illustrates an example of handpiece placement when performing a procedure on the abdomen of a subject using the frame (52b) illustrated in FIG. 6 (b) and the frame (52d) illustrated in FIG. 6 (d) together. Fig. 7(d) shows an example of the arrangement of the handpieces when performing a procedure on the abdomen of a subject using the frame (52c) shown in Fig. 6(c) and the frame (52d) shown in Fig. 6(d) together. Fig. 7(e) shows an example of the arrangement of the handpieces when performing a procedure on the left and right sides of the lower abdomen of a subject using two frames (52c) shown in Fig. 6(c). In addition, Fig. 7(f) shows an example of the arrangement of the handpieces when performing a procedure on the side of a subject using the frame (52c) shown in Fig. 6(c).

What is shown in Fig. 7 is only an example, and treatment can be performed on various body parts other than the abdomen or side of the subject. In addition, treatment can be performed by placing the handpiece in a shape not shown using various types of frames.

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

Referring again to Figure 1, the operator sets the type of treatment suitable for the subject, the treatment time, the number of handpieces to be used, etc., through the operating unit (12) installed in the main body (10). At this time, the handpiece to be used for the treatment may be attached to the subject through a fixing 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 in 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 in the handpiece (20) and the display unit (14) installed in the main body (10).

When it is confirmed 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 operating unit (12). For example, when the heating temperature for the fat tissue under the dermis layer is set to about 42 to 47, the LD module (22) is operated to irradiate a laser beam to the treatment area, and the LED module (24) is operated together to irradiate light to the treatment area, thereby starting the skin beauty treatment.

While the temperature of the treatment area reaches the set temperature and the fat decomposition treatment is being performed, the LED module (24) may be stopped, or the LED module (24) may be operated simultaneously with the irradiation of the laser beam. If necessary, the LD module (22) may not be operated and only the LED module (24) may be operated.

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). If the temperature of the handpiece (20) adjacent to the procedure site measured by the temperature sensor (26), for example, the cover (34), rises beyond the set range, the control unit (16) can temporarily suspend the operation of the LD module (22). At this time, the control unit (16) can display this information on the display unit (14) so that the equipment user can be aware of this. In addition, if the temperature of the handpiece (20) adjacent to the procedure site measured by the temperature sensor (26) falls below the set range, the control unit (16) can automatically restart the LD module (22) or display information on whether restarting is possible on the display unit (14) so that the user can operate it.

When the temperature of the treatment area rises above the set range and continues to rise abnormally or the handpiece (20) deviates from the fixed position, the control unit (16) notifies the operator of the abnormality by indicating at least one of the indicator light (30) installed on the handpiece (20) and the indicator (14) installed on the main body (10). If necessary, the control unit (16) can stop the operation of the LD module (22) even without the operator's operation.

When the set time has elapsed, the control unit (16) stops the operation of the handpiece and indicates on the display unit (14) that the treatment is complete.

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

FIG. 8 is a schematic perspective view of a handpiece included in a composite surgical device according to a second embodiment of the present invention. The composite surgical device according to the second embodiment of the present invention includes a main body and a handpiece, similar to the composite surgical device according to the first embodiment of the present invention illustrated in FIG. 1. However, for convenience, the main body is not illustrated in FIG. 8, and since the main body and the signal transmission unit are the same as those of the first embodiment, a description thereof will be omitted. Hereinafter, the composite surgical device according to the second embodiment will be described with a focus on the parts that are different from those of the first embodiment.

As shown in FIG. 8, the handpiece (120) according to the second embodiment is similar to the handpiece (20) shown in FIGS. 2 to 4 in that it includes an LD module (22) for lipolysis treatment and an LED module (24) for skin beauty treatment, but has a difference in that it has a roughly hemispherical handpiece body (132).

As in the first embodiment, one LD module (22) is positioned at the center of the reflector (138), and a plurality of LED modules (24) can be arranged on the reflector (138). The plurality of LED modules (24) can be arranged to be evenly distributed on the reflector (138).

In addition, the handpiece (120) according to the second embodiment can be rotatably mounted with respect to the handpiece body (132) in which the reflector (138) can be rotated together with the rotating reflector (138). Since some areas of the reflector (138) cannot reflect the laser beam from the LD module (22) as the LED module (24) is installed, there is a concern that shadows may occur even if only a very small area is present. However, if the reflector (138) is rotated, the concern that shadows may occur can be eliminated.

Although not shown in Fig. 8, the temperature sensor and contact sensor installed in the handpiece can 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 (not shown) of the fixing unit can be formed in a circular shape corresponding to the shape of the handpiece (120).

According to the present invention, it is not necessary for all handpieces equipped in a single composite surgical device to have the same shape, and the single composite surgical device may be modified so that a square handpiece (20) according to the first embodiment and a hemispherical handpiece (120) according to the second embodiment are equipped together.

In FIG. 8, the reflector (138) formed on the inner surface of the handpiece body (132) according to the second embodiment is illustrated as having the same shape as the reflector (38) of the handpiece (20) illustrated in FIGS. 2 to 4, but the shape of the reflector may be modified to be hemispherical to correspond to the hemispherical handpiece body (132).

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

As illustrated in FIG. 9, the composite surgical device according to the third embodiment differs from the composite surgical device according to the first embodiment in that the refrigerant circulation path (244) for flowing the refrigerant supplied from the cooling unit is installed in the frame (252) of the fixed unit (250) rather than the handpiece (220).

Fig. 9 illustrates a frame in which two handpieces (220) can be detachably mounted, and illustrates that 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 illustrated.

The composite surgical device according to the third embodiment may further include a separate refrigerant 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), or may further include a separate refrigerant path (not shown) connecting the handpiece (320) and the frame (352).

According to the third embodiment, the refrigerant circulation path (244) is installed in the frame (252) of the fixed unit (250) rather than the handpiece (220), so the handpiece (220) according to the third embodiment can be configured in the same way as the handpiece (20) according to the first embodiment, except that the refrigerant circulation path (244) 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 variations 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.

entity;
A handpiece connected to the main body through a signal transmission unit; and
Including a laser module placed inside the handpiece,
The above handpiece,
A handpiece body connected to the above signal transmission unit;
A cover connected to the handpiece body and having an opening including a protective window;
A reflector formed inside the handpiece body to reflect the laser so that the laser is irradiated entirely onto the opening;
A laser irradiation unit interposed between the laser module and the reflector and having a rough structure formed on one surface so that the laser is refracted and irradiated entirely onto the opening;
A cooling unit disposed inside the above main body; and
A refrigerant circulation path is provided to surround the protective window on the cover side inside the handpiece body and circulate refrigerant supplied from the cooling unit.
The above reflector is formed to be inclined so that the internal space widens at a constant angle of inclination as it goes from the signal transmission unit toward the cover, and is a treatment device that reflects the laser refracted by the laser irradiation unit to prevent the laser from being irradiated to the inside of the handpiece body and causing loss.
