BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suturing needle, and more particularly, to a method for easily and accurately forming a double eyelid in a short period of time, and is concerned about bruising, edema, and various complications expected after surgery. The double-blade burial suture of a special shape and structure that allows anyone to safely and safely undergo double-lid plastic surgery at low cost by eliminating the worry that the double eyelid will disappear later without having to worry about it It is about needles.

[0002]

2. Description of the Related Art In general, double eyelid surgery is the most frequently performed surgery in Northeast Asia such as Japan, Korea, and China due to race characteristics. Particularly in the case of Japan and Korea, it is estimated that about 20-40% of young women have undergone this operation. Most of Northeast Asia do not have double eyelids, but these eyelids are called single eyelids, and these eyes are covered by skin, resulting in small, unclear eyes, and expressionless and stiff May have the appearance. Therefore, many women in the region are undergoing double eyelid surgery (double eyelid surgery) to be beautiful, and this surgery occupies a very large proportion in the field of cosmetic surgery.

There are basically two types of double eyelid surgery. The first is an incisional method in which the skin of the eyelid is incised with a scalpel (incisional method), and the second is a non-incision method in which the skin is not incised at all but only with a needle.
incisional method), which have advantages and disadvantages.

[0004] The former is a method in which the skin of the eyelid is resected with a scalpel and then the formation of wound tissue in the tissue inside the eyelid to induce double eyelids. Instead of using at all, use a suture needle to tie the internal tissue of the eyelid at regular intervals and bury the knot of the suture so that double eyelids are formed when viewed from the outside It is.

Hereinafter, a conventional double eyelid treatment method and its side effects will be described with reference to FIGS. 1 to 10.
FIG. 1 is a cross-sectional view showing an eyelid when a person with a natural double eyelid closes his eyes, and FIG. 2 is a cross-sectional view showing the principle that wrinkles of the double eyelid are formed when a person with a natural double eyelid opens his eyes. FIG. 3 is a cross-sectional view showing the eyelids when a person who is not born with double eyelids opens his eyes. First, in FIG.
Reference numeral 10 denotes the skin of the eyelid. An eyeball 14 protected by the conjunctiva 12 is located inside the skin 10,
There is a levator levator muscle 18 including an eyelid plate 16 for moving the entire eyelid. The skin 10 and the levator levator muscle 18 are connected by a fibrous tissue 13. Reference numeral 30 denotes eyelashes, and reference numeral 32 denotes eyebrows.

[0006] The eyelid corresponds to the upper eyelid which serves to protect the eyeball. The eyelid is surrounded by the skin 10 (dermis layer) on the outside and the conjunctiva 12 on the eyeball side, in which various layers such as an oculomotor muscle layer, a fat layer, and a levator muscularis layer are arranged in order. . The eyelid plate 16 is a plate made of cartilage which is located at the deepest layer of the eyelid and maintains its shape so that the eyelid is not distorted. The levator oleum 18 is a muscle that functions to open the eyes, and the operation of opening the eyes refers to an operation in which the levator oleus 18 lifts the eyelid plate 16 upward. FIG.
FIG. 4 is a diagram illustrating the principle of occurrence of double eyelids. In the eyelid of a person having a wrinkle forming a double eyelid, there is a special fibrous tissue 20 or the like that connects the levator brevis muscle or the eyelid plate and the skin in order to realize the function of opening the eyes.
When the eyes are opened, that is, when the levator fold muscle 18 and the eyelid plate 16 are pulled upward, the skin connected to the fibrous tissue 20 is also pulled up, and the skin 10 is wrinkled. This is the double eyelid wrinkle W.

On the other hand, as shown in FIG.
Since the eyelids of a person who does not have the fibrous tissue 20 that connects the levator levator muscles 18 and the skin 10, the wrinkles W of the skin are not formed when the eyes are opened, and the skin gathers together in one place. However, it does not open suddenly and the eyes are not clear.

[0008] There are three types of conventional suture needles used for non-incision double eyelid surgery. FIG. 4 to FIG.
FIG. 5 is a front view showing a suture needle used for a conventional non-incision double eyelid surgery, and FIG. 4 is an enlarged view of the most common suture needle;
Is an atraumatic suture needle with a suture needle tied to one end of the suture.
FIG. 6 shows a bilateral atraumatic suture needle in which suture needles are tied to both ends of a suture. In these figures,
Reference numeral 100 denotes a suture needle. A needle hole 102 for passing a suture 200 is formed at one end of the suture needle 100 in a thick portion, and has a body 104 having a ring-shaped cross section.

In the case of FIG. 4, a knot is formed in the needle hole 102 so that the suture 200 does not fall out of the needle hole 102 during the operation. FIG. 5 shows an example in which a suture 200 is integrally formed at one end of the suture needle 100, and FIG. 6 shows an example in which the suture needle 100 is integrally formed at both ends of the suture 200. It is.

FIG. 7 is an explanatory view showing a situation in which a predetermined line of a double eyelid is set on the surface of the eyelid skin as a pre-stage for performing a non-incision type double eyelid operation in a general double eyelid operation, and FIG. FIG. 7 is an enlarged sectional view of an “A” part of FIG. In this drawing, a is the planned line of the double eyelid, A is the midpoint on the planned line a, b is the width of the double eyelid, that is, the scheduled line a of the eyelashes and the double eyelid.
The distance between them is shown. In FIG. 8, reference numeral 11 denotes the orbicularis below the skin 10.

FIGS. 9 to 14 are explanatory views showing the steps of a conventional non-incision type double eyelid surgery method using a suturing needle. In the conventional non-incision type double eyelid surgery method, the suturing needle 100 is usually inserted from the conjunctiva 12 side. First, as shown in FIG. 9, the suturing needle 100 attached to one end of the suturing needle 200 is passed through. To the skin 10 side. Thus, the first hole R on the conjunctiva 12 side and the second hole X on the skin side.
And one of the sutures 200 passes. For convenience of description, the suture needle 100 located at the top of the drawing is replaced with a first suture needle, a needle holder 300,
The grasped suture needle 100 is defined as a second suture needle.

Subsequently, as shown in FIG. 10, the second suture needle 100 is passed through the first hole R so as to emerge at a certain point on the separated conjunctiva surface. Open and return to the third hole Y again. As shown in FIG. 11, the second suture needle 100 is passed through all the layers of the eyelid,
Then, a fourth hole Z is made in the surface of the skin, and again, as shown in FIG.
Is passed through the fourth hole Z so as to pass between the skin 10 and the orbicularis muscle 11 and to come out to the second hole X. In this way, the suture 200 passes through the eyelid tissue in a square trajectory, with both tips exiting through the second hole X, and as shown in FIG. After the knot is formed by pulling the knot and the knot is completed as shown in FIG. 14, if the tip of the suture needle 100 is cut with scissors, all the stitches are buried in the skin, so that the 10 layers of the skin and the orbicularisus 11
The layers are connected and the operation is complete.

[0013] Such a conventional non-incision type double eyelid surgery,
A process of turning over the eyelid and exposing the conjunctiva 12 to the visual field must be performed. FIG. 15 is a perspective view showing the inner conjunctiva when the eyelid is turned upside down in general double eyelid surgery, and FIG. 16 is a cross-sectional view showing the state when the eyelid is turned upside down in general double eyelid surgery. . In these drawings, 310 is a support, 320 is a towing needle,
The state where the conjunctiva 12 inside the skin 10 can be seen from the outside by the support base 310 and the traction needle 320 is shown.

In order to make the conjunctiva 12 visible to the operator, the support 310 is placed on the skin 10 side, and the entire eyelid is pulled upward through the traction needle 320 at the end of the eyelid, whereby the eyelid is turned over. FIG. 16 shows that one point B of the skin 10 and one point B ′ of the eyelid plate 16 are shifted from each other. That is, the same point B ′ corresponding to the specific point B on the skin 10 side and the specific point B on the conjunctiva 12 side.
Causes positional displacement. There is no positional change at the specific point B on the conjunctiva 12 side of the eyelid plate 16 made of hard cartilage, but at the same point B ′ corresponding to the specific point B, the position in the direction in which the eyelid is pulled due to the elasticity of the skin 10 Displacement occurs.

[0015]

However, double eyelid surgery using the above-mentioned conventional suturing needle has the following problems. <General problems> 1. The non-incision double eyelid surgery method has the advantage that it does not leave traces of surgery, so it is better to apply it to people who hate putting a scalpel on the face or are worried about the scars of surgery,
When performing non-incision double eyelid surgery using existing suturing needles, it is inevitable that the eyelids are turned over to perform a complicated operation, which not only tends to cause swelling and bruising, Errors can occur, such as the formation of double asymmetrical double eyelids, suturing knots buried too shallow to form indurations, or the skin or conjunctiva epithelium may become involved with the implanted thread, resulting in cysts (cyst), can cause complications such as dermatitis, conjunctivitis, and eye damage. In addition, there is a high possibility that the wrinkles forming the double eyelids will easily disappear after the treatment. Such disadvantages in the conventional double eyelid surgery are largely due to the configuration of the existing surgical needle, that is, the suture needle itself, rather than the technical problem of the practitioner. It was difficult to find a practical solution.

2. The non-incision double eyelid surgery method has the advantage that a natural form of double eyelids can be made without leaving a mark, but there are many surgical errors and the double eyelids are easy to disappear, bruising,
Edema (edema), hematoma occurs and takes time to recover. 3. The procedure is cumbersome and takes a long time, requires the assistance of a skilled physician and a trained assistant, and the double eyelid procedure requires at least one week of treatment, and an additional period for treatment is indispensable after the treatment. 4. There is a high risk of kinking, depression, inflammation, conjunctivitis, ocular damage, cysts, suture knots, double eyelids coming off, etc. of the skin surface. 5. Only effective with narrow double eyelids, difficult for people with small eyes or when the eyeballs are depressed and the upper eyelid skin is thick. 6. During the operation, the patient has great anxiety and fear.

<Problems in Treatment> This problem is a complication caused by the occurrence of the situation shown in FIG. 16 when the treatment is performed in the order shown in FIGS. 9 to 14. The treatment according to the conventional method causes an error in the treatment and causes a problem illustrated in FIGS. FIG. 17 is a perspective view for explaining an oral state in which the form in which a suture is passed is indefinite, which often occurs when performing an operation using a conventional suture needle, and FIG. 18 is a state in FIG. FIG. 7 is a perspective view for explaining a state in which the skin is bent while the skin is pushed when the knot of the suture is completed. FIG. 17 shows a state in which a knot is formed in an irregular shape by the suture 200 being shifted through each tissue, and FIG. 18 shows a state in which the knot of the eyelid is bent 4 when the suture knot is completed.
10 shows a state in which it is formed.

Therefore, the error can be reduced by taking into account the error when passing the suture needle 100 and intentionally performing the treatment so that the tissue layer is shifted and passed.
Further, as the width of the double eyelid (b in FIG. 7) is increased, the width of the error is also increased. Therefore, it is difficult to apply the non-incision-type treatment method unless a thin double eyelid is to be formed. Also, when turning her eyes over, the patient feels that her eyes are pulled hard,
The internal pressure of the eyelid blood vessels and the like increases due to the force applied to the body in a reflexive manner. At this time, if the eyelid tissue is punctured with the suture needle 100, it bleeds easily from the surface of the punctured part, and a hematoma is formed inside. Yes, this causes the eyelids to swell.

The most difficult part of the conventional double eyelid surgery is the process of returning from the holes R, X, Y and Z through the suture needle 100 as shown in FIGS. However, not only is it not easy to find the hole made by the suture needle 100 and pass it through the suture needle 100, but bleeding continues and it is difficult to find the correct hole. FIG. 19 is a perspective view illustrating an example of a complication that occurs when a non-incision type double eyelid surgery is completed using a conventional suturing needle. It is difficult to find the hole at one time, and bleeding, bruising, and edema become severe each time the hole is searched several times during the operation. If this process is not performed correctly, the suture 200 may protrude toward the conjunctiva 12,
The epithelium of the skin 10 and the conjunctiva 12 penetrates about the suture 200, and it is not a normal operation. In the case of F in the figure,
The suture 200 is projected out of the skin 10 and passes therethrough, causing a depression phenomenon on the surface of the skin 10. G
In this case, the suture 200 is exposed to the outside of the conjunctiva 12 and passes therethrough, resulting in conjunctivitis and eye damage. In the case of H, the knot of the suture is buried very shallowly, and the contour of the knot on the surface of the skin 10 is protruded to form induration, which may lead to complications in which the knot comes out through the skin.

The practitioner is reluctant to create multiple suture knots to prevent double eyelids from falling off, because of this danger. Normally, only one or two buried sutures can be made on the eyelid, and there is a risk that it will not be known when it will be taken. In addition, it is difficult to apply this surgical method to a subject who has difficulty turning over his or her eyelids, that is, a person with small eyes, a depressed eyeball, or a person with thick upper lid skin.

[0021]

SUMMARY OF THE INVENTION The present invention has been made in order to overcome the technical limitations of existing suture needles in the above-mentioned conventional non-incision double eyelid surgery, and has as its object a short time. Within the easy and accurate double eyelid surgery,
A special, low-cost, pain-free and safe double-lid procedure that eliminates the risk of bruising, edema, and possible complications after surgery, and avoids worrying about later complications. It is an object of the present invention to provide a double-edged suturing needle having a complicated structure.

In order to achieve the above object, a double-edged implantable suture needle according to the present invention is a suture needle comprising at least a main body and a needle hole for passing a suture formed in a predetermined portion of the main body. It consists of a curved part and a straight part, and the tip of the curved part and the straight part forms a sharp needle blade, and the curved part forms a very gentle curve of about 1/4 circle, and is generally hook-shaped. It is characterized by being. Therefore, the dermatitis, bursa,
There is no conjunctivitis eye damage, no knot protrusion outside the skin, etc., and when using a conventional suture needle, a doctor with skill and abundant experience must perform surgery with the help of an excellent assistant. However, the double-edged suturing needle of the present invention does not require the assistance of an assistant, and can be operated only by a doctor, so that a general doctor who is not an orthopedic surgeon can easily perform the operation.

In the above construction, it is preferable that the needle blade in the curved portion is an isosceles triangle and the needle blade in the straight portion is a conical shape, and the needle hole has a whole width at the widest part of the needle blade.
It is preferable that two pieces are formed with a diameter within 1/3,
It is preferable that the needle blade in the straight portion is formed so as to form an angle of 90 degrees with the needle blade in the curved portion. It is preferable that the tip of the needle blade of the straight portion is square or conical, and the cross-sectional shape of the main body is preferably elliptical or square with a corner.

According to another aspect of the present invention, there is provided a double-ended implantable suture needle comprising at least a main body and a needle hole, wherein the main body is entirely semicircular.
A sharp needle blade formed symmetrically on the left and right sides of the main body, and the needle hole is formed on one side of both needle blades. In such a configuration, it is preferable that the needle holes are respectively formed on both needle blades. The present invention thus configured provides a surgical needle comprising a curved portion and a straight portion, the curved portion assisting the suture to easily penetrate the deep tissue of the eyelid, and the straight portion being a portion where the suture is the skin. Of the skin, do not turn over the eyelids on the preset line a of the double eyelid while the patient closes his or her eyes for about 10 minutes during the operation. Creates a double eyelid simply by inserting it inside, and the suture knot is buried deep in the skin, so that when the patient opens the eye, the double eyelid is formed, minimizing fear of surgery Therefore, in performing non-incision double eyelid surgery,
Because the process of turning over the eyelids is not required at all, it is possible to freely operate a wide double eyelid, not only for people with small eyes or for which the upper eyelid is depressed, but also for the elderly and the sick, etc. The target of the treatment is not limited to the patient who was difficult to operate with the surgical method, the production cost is low, and it can be used repeatedly several times, so it is economically advantageous and short time
Many patients can be operated in the hospital, and the operation cost is low.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 20 is a front view showing an embodiment of a double-edged implantable suture needle of the present invention, and FIG. 21 is a plan view of the same. The same or corresponding parts as those in the conventional example will be described with the same reference numerals. Now, FIG. 22 to FIG.
It is explanatory drawing showing the process of the non-incision type double eyelid surgery using the double-edged implantable suture needle of this invention. The double-edge implantable suture needle 100 of the present invention is roughly divided into a main body 104 and a curved portion 130 and a straight portion 140 formed at both ends of the main body 104. The cross section of the main body 104 has an elliptical shape, and sharp needle blades 132 and 142 are formed at the ends of the curved portion 130 and the straight portion 140, and the curved portion 130 has a very small circle of about 1/4. Make a gentle curve,
It has a hook shape overall. As shown in FIGS. 20 and 21, in the embodiment, the curved portions 130 and the straight portions 140 have needle blades 132, 142 having a flat spindle shape.
Are formed respectively. The tip 132a of the needle blade 132 has an isosceles triangular pyramid shape, and the tip 142a of the needle blade 142 has a polygonal pyramid shape.

Reference numeral 102 denotes a needle hole, which is set and formed at the widest part of the needle blade 132 with a diameter within 1/3 of the entire width. In this embodiment, the needle hole 102 is formed not only at the position of the needle blade 132 but also at the needle blade 142 of the straight portion 140. In addition, as shown in FIG.
42 is formed so as to have a 90-degree angle difference with respect to the needle blade 132.

The method of double eyelid surgery using the double-edged implantable suture needle according to the above embodiment will be described with reference to FIGS. 22 and 23. First, after a very thin nylon thread is passed through the needle hole 102, the eyeball 14 is locally drunk, and a contact lens for protecting the eyeball is worn. Needle holder 300
The straight portion 140 is clamped by the needle blade 13 of the curved portion 130.
In step 2, the first perforation point on the expected double eyelid line a (see FIG. 7) is passed vertically (step).

Subsequently, when the needle blade 132 reaches the hard eyelid plate 16, the suturing needle 100 is made horizontal to pass through the eyelid plate 16 (step, step). In FIG. 22, the suture 200 is omitted to avoid complication of the drawing. After the tip of the needle 132 has passed the surface of the cartilage plate horizontally, it passes through the second perforation point on the expected double eyelid line a and exits the skin 10 (step). Thereafter, the needle holder 300 at the straight portion 140 is removed, and the double-edged suture needle 100 is retracted by piercing the curved portion 130 coming out of the second perforation point. At the moment when the tip of the needle of the straight portion 140 has completely exited the eyelid plate 16 and the levator brevis muscle 18, the reverse movement is stopped.
The direction of the 0 needle blade 142 is changed to the skin 10 side (FIG. 23).
Virtual line arrow direction). As described above, the double-edged implantable suture needle 100 of the present invention is configured to have needle blades at both ends thereof.
Because it is possible to reciprocate freely in the skin, simply change the direction in the tissue and change the direction after completely removing the double-edged suturing needle 100 out of the skin 10 from the conventional surgical method. Instead of pushing it back to its original position.

Further, the needle blade 142 of the straight portion 140 is set up vertically as in the cross section of the tissue, so that it is easy to change the direction in the direction of the arrow in FIG. 23 without resistance of the tissue. continue,
The suture needle 100 is advanced in the opposite direction with the straight section 140 forward, but is inserted at the lowest level of the skin toward the first perforation point on the expected double eyelid line a. The straight structure of the straight portion 140 allows the tip of the needle blade 142 to easily reach the lowermost tissue of the skin, and is also convenient for advancing the suture needle 100 in the horizontal direction. In addition, while the suture needle 100 is passing through the lowermost layer of the skin, the outline of the upper frame of the vertical straight portion 140 and the needle blade 142 according to the present invention appears on the surface of the skin 10 so as to protrude. It is more desirable to let 100 pass through in line with the expected double eyelid line a.

Subsequently, as shown in FIG.
When the tip of the 40 needle blades 142 is close to the first perforation point, the needle is stabbed slightly deeper, passes through the deepest part, and is completely pulled out of the skin 10 through the first perforation point. The reason for the deep penetration of the needle in the last stage of the passage is that the suture knot is guided so as to be buried as deeply as possible in the skin, and the suture knot is exposed on the surface of the skin 10 as shown in FIG. This is to prevent that. Since the eyelid skin moves up, down, left and right flexibly, the needle blade can be freely passed through the tissue, so that the series of steps from FIG. 23 to FIG. 25 can be easily performed by one operation.

In the final stage, the thread ends 250 on both sides are pulled, a suture knot is formed, and the ends of the thread are cut with surgical scissors 260, so that the suture knot is buried in the skin. Completed. As described above, the non-incision-type double eyelid surgery using the double-edged implantable suture needle 100 of the present invention accurately forms wrinkles of the double eyelid on the expected double eyelid line a without error, and forms a fine needle hole 2 on the surface of the skin. Can be
This hole heals within 12 hours and does not require medication or additional treatment after the procedure. Through such a series of surgical procedures, the skin 10 tissue and the levator levator muscle 18 are firmly connected by the suture thread 200. At the moment when the eyes are opened, the eyes of the patient change to double eyelids, and almost no edema or bruises are formed. After about 1 to 2 hours, you will be able to work immediately. In addition to solving all the disadvantages of conventional non-incision double eyelid surgery, it is possible to return to the original state at any time after the operation if desired by the patient, and all the processes can be completed in one operation in a short time (about 10 minutes) In addition to being terminated, it is possible to do activities immediately after treatment, so if you are a foreigner,
It is possible to cooperate with tours because it allows you to perform sightseeing tours to neighboring countries where treatment costs are low.

The double-edged implantable suture needle of the present invention is applicable to other surgical fields. In women, outside eyebrows begin to hang down from the middle of their thirties onwards, but in order to prevent this, it was conventionally corrected by plastic surgery or endoscopic wrinkle plastic surgery,
When using the double-edged implantable suture needle of the present invention, it is possible to easily correct the drooping skin by fixing it to the periosteal tissue deep in the forehead without putting a scalpel on the face. In addition, the present invention can be applied to a surgery for correcting a facial wound of an infant.

The double-edged implantable suture needle of the present invention can be deformed into various shapes when used on tissues other than the eyelids. FIG.
FIG. 27 is a front view showing a second embodiment of the double-edged implantable suture needle of the present invention, FIG. 27 is a front view showing a third embodiment of the double-edged implantable suture needle of the present invention, and FIG. 28 is a plan view thereof. FIG. 29 is a front view showing a fourth embodiment of the double-edged implantable suture needle of the present invention.

The double-ended implantable suture needle according to the second embodiment shown in FIG. 26 has the same overall shape as that of the first embodiment, and the tip 144 of the needle blade 142 of the straight portion 140 has a conical shape. On the other hand, the tip 13 of the needle blade 132 in the curved portion
2a is formed in a triangular pyramid. In such an embodiment, even a novice practitioner can easily perform the operation because of the round needle-shaped tip 144 having a fine curve.

The third embodiment of the double-edged suturing needle of the present invention shown in FIGS. 27 and 28 is generally semicircular or 3/8 circular, and the cross section of the main body 104 is square or circular. ing. Needles, ie, needle blades 132 and 142, which are pointed symmetrically at both ends around the main body 104, are formed. The needle hole 102 may be formed in all the needle blades, or may be formed in either one of them. In such a case, the embedding suture between the deep tissue layers is particularly easy.

The second embodiment of the double-edged implantable suture needle of the present invention shown in FIG. 29 is generally the same as that of the first embodiment, but the needle blade 142 of the straight portion 140 and the curved portion 130
There is a difference in that a 90-degree angle difference is not provided with the needle blade 132 and the tip 146 of the needle blade 142 also has a triangular pyramid shape. In this case, it is more conveniently used in tissues other than the eyelids. The tips of the needle blades 132 and 142 are both triangular pyramid-shaped.

[0037]

According to the double-edge implantable suture needle of the present invention as described above, the surgical needle is composed of a curved portion and a straight portion, and the curved portion facilitates the penetration of the deep tissue of the eyelid by the suture and the straight portion. Make sure that the suture passes exactly through the lower layer of the skin, and during the procedure, while the patient closes his eyes for about 10 minutes, the suture needle should not be turned over over the preset double eyelid line. A double eyelid is created simply by placing it in the skin, and the suture knot is buried deep in the skin, creating a double eyelid when the patient opens his eyes, minimizing fear of surgery. In the case of non-incision type double eyelid surgery, the process of turning over the eyelid is not required at all, so the wide double eyelid can be operated freely, and it is only for those who have small eyes or who have collapsed the eyelid Old man and sick without Sha, etc., in the conventional surgical methods can receive up to the person to be treated treatment was difficult, safely and comfortably surgery. In addition, the manufacturing cost is low, and it can be used repeatedly several times, so that it is economically advantageous, and it is possible to operate a large number of patients in a short time and reduce the cost of the operation. In addition, by minimizing other tissue damage during surgery, the occurrence of edema and bruising is reduced, and the subject can take a vacation or travel immediately after the procedure, or perform the procedure on Saturday and work or work on the next Monday. You can go to school and do not disturb your life. Especially when considering the difference in exchange rate with foreign currency,
A shaping tour from a neighboring country is also possible, which greatly contributes to the foreign currency acquisition of the operating country.
