Description

Medical thread insertion device that enhances the convenience of the procedure {MEDICAL THREAD INSERTION DEVICE THAT ENHANCES THE CONVENIENCE OF THE PROCEDURE}

The present invention relates to a medical thread insertion device that enhances the convenience of the procedure, and in more detail, in a thread insertion structure in which a thread formed inside and outside the needle wraps the surface of the needle in a spiral shape, it is exposed from the inside of the needle to the outside and is exposed to the surface of the needle. The first thread that is seated and provides the main traction force of the skin tissue and the surface of the needle and the second thread that wraps the above-described first thread in a spiral shape and strengthens the traction force of the first thread are provided, thereby providing convenience of the procedure as well as the manufacturing process. It relates to a medical thread insertion device that can be provided.

Medical thread has been widely used in the past to provide a suture function for surgery, but recently, with the development of a melting thread, it has been widely used for skin beauty through a tightening procedure that provides elasticity and regeneration effect while preventing sagging of the skin.

In order to inject a medical thread into the skin tissue, a thread inserting device is applied in which a medical thread having a certain diameter is accommodated in a hollow, and then a sharp tip is pierced into the skin tissue and the received thread is injected into the skin tissue.

Such a thread insertion device is advantageous to accommodate a thick thread rather than a thin thread in order to increase the effect of the procedure. In this case, there is a disadvantage of bleeding and bruising due to the occurrence of unnecessary large holes in the treatment area of the skin tissue. In order to solve this problem, a thread insertion device having a thread having a helical structure surrounding the circumference of the needle has been developed, so that even when a relatively thin thread is used, the treatment effect due to the helical structure can be increased.

However, this thread insertion device has a problem that the spiral structure is easily solved not only during injection of skin tissue, but also during normal times.

1 is a cross-sectional view showing a schematic structure of a conventional thread inserter.

The prior art according to FIG. 1 relates to a basic embodiment of a thread inserter of Korean Patent No. 1811208, a needle 1 having a sharp tip and extending in the longitudinal direction and having a hole open from the tip therein, and the The first extension part inserted into the hole of the needle 1 and the winding part extending from the first extension part and wound around the needle in the longitudinal direction of the needle outside the hole of the needle 1 and the winding part It includes a thread (2) having a second extension portion forming a knot portion that is tied to prevent loosening, and when the thread (2) is inserted into the human body by the needle (1), the winding portion of the needle (1) It is guided and remains inside the human body in a shape tightly wound around the circumference, and the knot portion includes at least one binding portion wound so as to be staggered around the needle.

In other words, the thread (2) extends in a spiral shape from the inside of the needle to the outside, and is tied with a knot with the end of the end to prevent the thread from being unwound arbitrarily, while inserting several strands of thread by the thread of the spiral structure. It is posted that there is an effect that can achieve a more excellent treatment effect.

However, the spiral structure is not an original structure with only the above technology, but a technology that exists before that, and the core of the technology is to provide a knot to prevent loosening. However, thick threads are applied to obtain an excellent treatment effect. Even so, forming a knot at the end of the thread is a cumbersome or difficult task.

In addition, since the thread is extended to the inside and outside of the needle through a single thread, there is a risk of the thread breaking when winding in a spiral, and the diameter of the thread inserter itself increases as it wraps around the needle, resulting in a hole that is pierced into the human body. The problem itself also grows.

In addition, when the helical structure wound around the needle is injected into the skin tissue, there is a problem that the helical structure is not maintained in the skin tissue due to the problem of being crushed by the repulsion of the skin tissue, and thus it is difficult to properly obtain the above-described treatment effect.

Therefore, a thread having a structure extending in and out of the needle and a helical structure surrounding the circumference of the needle is provided, but a more unique structure is provided by separating the thread having the needle structure and the thread having a helical structure, and the thread is not easily loosened. At the same time, there is a need to develop a new and advanced medical thread insertion device that can maximize the effectiveness of the procedure as well as the convenience of the procedure.

The present invention has been devised to overcome the problems of the above technology, and proposes a structure in which the main thread (first thread) providing traction is extended from the inside of the needle to the outside, so that the diameter of the needle is not too large, Its main purpose is to provide a thread insertion device separately provided to secure the convenience of manufacturing and operation of an additional auxiliary thread (the second thread) that wraps the main thread in a spiral shape and assists the traction force.

Another object of the present invention is to conveniently and safely fix the above-described main and auxiliary threads to the guide ring.

Another object of the present invention is to provide a means capable of stably receiving the main thread on the outer circumferential surface of the needle without unnecessarily protruding.

A further object of the present invention is to provide a means of preventing unnecessary slipping at a portion where the second thread is fixed via the first thread, thereby forming a helical shape without the problem that the second thread is idle.

In order to achieve the above object, the medical thread insertion device for enhancing the convenience of the procedure according to the present invention includes: a needle having a hollow and an opening in which the tip of the hollow is opened; A first thread inserted into the hollow and extended along the length direction of the outer peripheral surface of the needle by being bent to contact the outer peripheral surface of the needle after being exposed to the opening portion; And a second thread which is inserted between the bent portions of the first thread and then folded to collect the generated strands and wraps the outer circumferential surface of the needle and the first thread located therein in a spiral manner.

In addition, the first thread is characterized in that the diameter is larger than that of the second thread.

In addition, the medical thread insertion device is characterized in that it comprises a guide ring that is formed in a ring shape and is fitted to an outer circumferential surface of the needle on which the first and second threads are located.

In addition, a guide groove is formed on an outer circumferential surface of the needle to which the first thread is in contact with the needle, and a guide groove extending along the length direction of the needle is formed, and the first thread is inserted into the guide groove and is inserted into the guide groove on the outer circumferential surface of the needle. It is characterized by being extended.

According to the medical thread insertion device for enhancing the convenience of the procedure according to the present invention,

1) By separately providing the first thread, which is the main thread that performs the traction function of the skin tissue, and the second thread, which is the auxiliary thread that wraps the surface of the needle in a spiral shape, the first and second threads are conveniently The thread can be fixed to the needle, providing convenience for manufacturing and treatment,

2) The first and second threads can be more conveniently fixed to the needle through the guide ring, and the convenience of the procedure can be enhanced.

3) By placing the first thread in the guide groove, not only can the overall diameter of the thread insertion device be prevented from being unnecessarily thickened, but also

4) By specially treating the portion of the first thread that the second thread touches, it has the effect that the second thread can be rotated to stably form a spiral shape without idling.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and the same reference numerals in each drawing refer to the same components.

2 is a cross-sectional view showing the overall appearance of the medical thread insertion device of the present invention, and FIG. 3 is a conceptual diagram showing a structure and sequence in which first and second threads are coupled to a needle.

As can be seen from FIG. 2, the medical thread insertion device of the present invention basically consists of a needle 100 and a first and second threads 10 and 20 that are coupled to the needle 100 but are separated from each other. .

The needle 100 has at least one end, that is, an opening 120 that is open so that the tip is in communication with the hollow 110 in a state having a hollow 110 through which the inside is formed, like a known medical needle.

At this time, the tip of the needle 100 takes a structure that is sharply formed so that it can be easily inserted into the skin, or has a relatively blunt tip, such as a cannula type needle, which is currently widely used as shown in FIG. 2 It is also possible to form a structure in which the tip-side opening 120 is partially cut along the length direction of the outer circumferential surface of the cannula to extend.

The rear end of the needle 100 may be combined with a handle 30 consisting of one or two stages to take the same or similar structure as a syringe as a whole, while a practitioner such as a doctor manipulates the handle 30 by pressing the handle 30. The first thread 10 and the second thread 20 coupled to the needle 100 may be injected into the body. Since the handle 30 is a well-known structure, a separate description will be omitted.

The threads 10 and 20 of the present invention, that is, the first thread 10 and the second thread 20, may be made of known sutures. In particular, by being inserted into the skin tissue and lifting the aged skin, wrinkles and sagging are prevented. Its main purpose is to perform the skin care function of preventing and improving elasticity.

These first and second chambers 10 and 20 are made of a material that can minimize side effects and allergic reactions by melting in the skin tissue after a certain period of time, for example, polydioxanone (PDO), or further known as a collagen formation promoting substance. It may consist of or at least include Poly L Lactic Acid (PLLA) or Polycaprolacton (PCL).

Here, PDO has the advantage of having a relatively long half-life and less tissue reaction compared to other melting sutures, and PCL has a characteristic that it can remain in the skin for a longer time.

At this time, the first and second chambers 10 and 20 are basically made of the same material, but are not limited thereto and may be made of different materials. For example, the first chamber 10 is PDO and the second chamber 20 ) May consist of PCL.

More specifically, as can be seen from FIG. 2, the first thread 10 is inserted into the hollow 110 of the needle 100 and extends to a certain length along the length direction of the hollow 110, and then the needle 100 The open part 120 of the open part 120 is exposed outside, and the part exposed outside the open part 120 is bent toward the outer circumferential surface of the needle 100, and then in contact with the outer circumferential surface of the needle 100, or in a seated state, the needle 100 It takes a structure that extends a certain length along the length direction of ).

In other words, it can be seen that the first thread 10 consists of a portion located inside the needle 100 and a portion located outside the needle 10.

That is, if the first thread 10 is located only inside the needle 100, it is difficult to properly penetrate the first thread 10 in the needle 100 into the skin tissue during the tying procedure, and in order to solve this problem, the diameter of the needle 100 In this case, the first thread 10 can be accurately injected into the desired skin tissue while minimizing the diameter of the needle 100, since it must be made large. In this case, the first thread 10 can be accurately injected into the desired skin tissue while minimizing the diameter of the needle 100. The first thread 10 is bent and extended so as to be positioned over the inner and outer sides of the needle 10 so that it can be.

The second thread 20 is injected into the skin tissue together with the first thread 10 while enclosing the first thread 10. In particular, the outer circumferential surface of the needle 10 and the agent seated on the outer circumferential surface in a spiral shape. 1 Since it has a shape that surrounds the thread 10, the overall structure of the thread inserted into the skin tissue is improved to have a solid shape preservation, and the repulsive force of the skin tissue secures sufficient traction without the problem of being easily broken in the skin tissue. You can maximize the skin improvement effect.

In other words, the thread 10 and 20 of the present invention is not made into a spiral shape by extending the needle from the one received inside the needle as a single thread as in the known technology of FIG. 1, as two threads inside and outside the needle 100 After dividing the first structure extended into the second structure and the second structure surrounding it in a spiral form, one (the second thread 20) creates a second structure, that is, a spiral shape to ensure the stability of the yarn as a whole, and the other (the first thread 20). (10)) is the first structure to provide the main function of performing traction in the skin tissue while providing a base role such as a pillar on which the second thread 20 can be wound.

Specifically, as can be seen from FIG. 3, the second thread 20 is a bent portion of the first thread 10, and more specifically, the first thread 10 is exposed to the opening 120 so that the needle 100 is The middle of the total length of the second thread 20 with one end in the space between the folded parts so as to adhere to the outer circumferential surface (the space surrounded between the first thread 10 and the needle 1 as the inner space of the first bent part) When the part is inserted, the inserted part and the non-inserted part become two strands of similar length, and the exposed part of the outer circumferential surface of the needle 10 and the first thread 10 seated on the outer circumferential surface with both strands collected Has a structure wrapped in a spiral shape.

That is, the second thread 20 enters approximately half of the total length between the folded portions while the first thread 10 is exposed from the hollow of the needle 100 to the outside, and then the needle 10 is folded through both strands. It is wrapped in a spiral shape on the outer circumferential surface.

Due to this structure, since the spiral structure made by the second thread 20 is based on two threads, it is possible to ensure the rigidity that does not break easily.

At this time, the end of the helical structure of the second thread 20 is applied to the end of the second thread 20 by applying a bio-friendly adhesive means (eg, mussel foot protein) to the end of the second thread 20 without having to form a knot. In the needle 100 by attaching to one side of the outer circumferential surface of (10), winding the end of the second thread 20 tighter than the other part, or inserting it into a fixing groove (not shown) separately formed on the handle 30 side. It is possible to fix it so that it does not easily come off or loose in the first chamber 10.

That is, the first thread 10 mainly performs the function of providing traction to the skin tissue, whereas the second thread 20 has a three-dimensional effect of the entire medical thread of the present invention due to the inherent helical structure wound around the needle 10. The main function is to highlight and prevent the problem from being easily cut off or loosened in the skin tissue.In other words, the second thread 20 forms a helical structure to assist the traction of the first thread 10 and reduce the overall thread resistance. It performs the function of increasing the preservation power in the skin tissue by emphasizing the three-dimensional effect.

In particular, in order to fix the second thread 20 to the needle 100 more quickly and simply, as well as to prevent the diameter of the thread insertion device from unnecessarily increasing due to the convenience of forming a helical structure and the helical shape, the second thread More preferably, the diameter 20 is smaller than that of the first thread 10.

In this way, when the second thread 20 is thinner than the first thread 10, it is easier to wind the end of the first thread 10, which is relatively thick, so that the end is in close contact with the needle, or a peripheral configuration such as the handle 30 The second thread 20 can be conveniently fixed to the needle without having to go through the cumbersome work of making a knot. At this time, since the first thread 10 is wound in a spiral shape by the second thread 20, it is not necessary to perform a fixing operation such as knotting separately.

In addition, the lengths of both prongs of the second thread 20 are not necessarily the same, and one side may be longer or shorter.

As described above, according to the thread insertion device of the present invention in which two threads, the first and second threads 10 and 20, are fixed to the needle 10, the end of the thread 2 is attached to the needle 1 as in the known art of FIG. Without the inconvenience of forming a knot for fixing, it can be easily fixed to the needle 10 in various ways through a second thread 20 that is separated from the first thread 10 independently. Unlike in the case that the thread 2 wound around the needle 1 can be injected into the skin tissue only when the operator pushes the fixing ring 3 as shown in Fig. 1, only the operation of manipulating the handle 30 without the fixing ring 3 is sufficient. It provides convenience that the seal 10 can be smoothly injected into the skin tissue together with the second seal 20.

In addition, in the known technology of FIG. 1, the thread 2 surrounding the outside of the needle 1 must perform a traction function in the skin tissue, so the diameter must be guaranteed at a certain level. Wrapping the needle (1) in a spiral structure inevitably increases the overall diameter of the thread inserter, resulting in a problem that also increases the hole formed in the skin tissue, but in the present invention, the thread mainly performing the traction function, that is, the first Since the thread 10 is attached only to one side of the outer circumferential surface of the needle 100 and at the same time forms a helical structure with a second thread 20 having a smaller diameter than this, the overall diameter of the thread insertion device is not relatively thick, so it is not affected by the skin. It can provide the advantage of reducing unnecessary large holes or pain-causing problems.

Furthermore, the known technology is that the thick thread 2 is all wrapped around the needle 1, so that the thread 2 itself is crushed due to the repulsion of the skin tissue during the process of being injected into the skin tissue. There is a problem that cannot be maintained. However, in the first and second threads 10 and 20 of the present invention, in the state that the first thread 10, which is a thick thread, is attached to one side of the needle 100 rather than the entire circumference, the second thread ( Because it is wound by 20), it is possible to preserve the original shape without being crushed easily even when the first thread 20 is injected into the skin tissue by the protection of the second thread 20, so that the basic function of the first thread 10 is maintained as it is. Provides a property that can be retained.

4 is a cross-sectional view illustrating a state in which a cog is formed in the first and second threads.

At least one of the first chamber 10 and the second chamber 20, and as can be seen from FIG. 4, both the first and second chambers 10 and 20 are spaced apart from the outer circumferential surface of a plurality of cogs 11, It is possible for 21) to be formed.

The cog (11, 21) expands the surface area of the first thread (10) or the second thread (20) to reinforce the contact force with the skin tissue, as well as play a role as an anchor point that engages in the skin tissue. can do.

These cogs (11, 21) can be made of various three-dimensional structures, for example, a structure inclined toward the tip, a structure formed alternately from the left and right around the first and second chambers (10, 20), etc. It is possible to provide.

5 is a cross-sectional view showing a state in which a guide ring is coupled to a needle to which first and second threads are coupled.

As can be seen from FIG. 5, the medical thread insertion device of the present invention includes a guide ring 130 formed in a ring shape and the outer peripheral surface of the needle 100 to which the first and second threads 10 and 20 are coupled (approximately It is possible to fit on the lower side).

This guide ring 130 has a shape similar to that of the known art fixing ring 3 of FIG. 1, but differs in function and action.

Specifically, the guide ring 130 of the present invention provides a role of fixing the second thread 20. That is, the guide ring 130 is made of a soft material, not a hard material, and provides a basis for the second thread 20 to be conveniently fixed to the needle as a result by inserting the end of the second thread 20.

To this end, the guide ring 130 is made of a porous elastic material such as a sponge, and is inserted into the needle 100 by inserting the end of the second thread 20 as well as the remaining end of the first thread 10 as necessary. ,2 It is desirable to easily fix the thread (10,20).

In addition, since the guide ring 130 is in direct contact with the first and second threads 10 and 20, the guide ring 130 is the tip of the outer circumferential surface of the needle 100 While moving in the direction, it is possible to provide a sufficient contact area to push the first and second chambers 10 and 20 together into the skin tissue.

The fixed ring 3 of the known art of FIG. 1 has the inconvenience that the operator must grab and push the fixed ring 3, but the guide ring 130 of the present invention does not require the operator to contact the handle 30. The first and second threads 10 and 20 can be pushed together in the direction of the tip of the needle 100 while moving in the direction of the tip of the needle 100 only by the operation of.

Furthermore, the guide ring 130 made of a porous elastic material structurally has a plurality of holes 131, and the inside of the hole 131 or itself is a lubricant made of at least one of natural oils such as lanolin oil and olive oil. It is possible to include 132.

That is, when natural oil is immersed in the skin tissue, it can provide a function as a lubricant 132 that provides a unique moisturizing function as well as assisting cell regeneration or supplying nutrients to the skin. Since 130) is made of a porous foam structure like a sponge, such natural oil, that is, lubricating oil 132 can be easily contained in the guide ring 130, providing a lubricating function to the outer circumferential surface of the needle 100, as well as some When it penetrates into the skin tissue, it can assist the function of helping cells regenerate.

That is, the lubricating oil 132 can be naturally discharged by the compression force generated when the operator manipulates the handle 30 to move the guide ring 130 in the direction of the tip of the needle 100. As a result, it is possible to prevent a problem in which the shape of the first and second threads 10 and 20 is deformed while the guide ring 130 is not easily pushed or pushed against the surface of the needle 100, that is, the outer circumferential surface.

Olive oil is an oil obtained from the fruit of the olive tree and contains essential fatty acids necessary for the skin. Representative examples include oleic, palmitic, and linoleic acids.

The main component of these fatty acids is oleic acid, which is an unsaturated acid, and its content is about 65 to 85%, and palmitic acid is the main component as a saturated fatty acid. It also contains phenolic compounds with antioxidant properties. Accordingly, in the process of moving the guide ring 130 by the operator manipulating the handle 30, a part of the guide ring 130 is compressed, and the olive oil is discharged to the outer peripheral surface of the needle 100 to discharge the surface of the needle 100. In addition to providing the lubricating function of the skin, it can provide a beneficial function within the skin tissue.

Lanolin oil is an oil extracted from the wool of cotton, and has an ingredient close to human sebum, so it has excellent skin absorption properties, and also has excellent moisturizing and moisture absorption properties. In addition, lanolin oil is highly emulsified, so that about 80% of water can be made into a colloidal form, and thus it can exhibit an emulsifying function in which oil and water are mixed without an emulsifier. Like the olive oil described above, such lanolin oil may provide a lubricating function of the needle 100 and a moisturizing function within the skin tissue.

In summary, the guide ring 130 serves as a fixing medium capable of fixing the first and second threads 10 and 20 to the needle 100 and has a surface area in contact with the first and second threads 10 and 20. In addition to providing a role to conveniently push the first and second threads 10 and 20 when the operator manipulates the handle 30 by expanding, the needle 100 through the lubricating oil 132 of natural ingredients is provided. It provides lubricity to ensure smooth mobility on the surface.

6 is a conceptual diagram showing a coupling relationship between a guide groove formed on an outer circumferential surface of a needle and a first thread.

As mentioned above, since the first thread 10 plays a pivotal role in providing traction for skin beauty/regeneration, a certain thickness must inevitably be secured. If it is seated on the outer circumferential surface of the needle 100, the first thread 10 The overall diameter of the thread insertion device of the present invention is also increased by the diameter of (10), and thus the probability of increasing the diameter of the affected part is followed.

In order to solve this problem, it is possible to form a guide groove 140 recessed and extended along the length direction of the needle 100 in a portion of the outer circumferential surface where the first thread 10 is seated in the needle 100.

As can be seen from FIG. 6, since the first thread 10 exposed from the opening 120 of the needle 100 is immediately bent and then seated on the outer circumferential surface of the needle 100, the guide groove 140 is Without a separate jaw, the first thread 10 can be seated therein by being recessed from the area around the opening 120 of the needle 100 and extending along the lengthwise direction of the needle 100.

Thereby, due to its own diameter of the first thread 10, the thread insertion device of the present invention provides a characteristic capable of preventing a problem in which the thread insertion device of the present invention is thickened or the diameter is increased.

Furthermore, when the operator manipulates the handle 30 and injects the first chamber 10 (including the second thread 20) into the skin tissue, the tip of the guide groove 140 is pushed to the skin tissue. In order not to interfere with the movement path of (10), the boundary portion on the tip side of the needle 100 in which the guide groove 140 is formed is not angled and is chamfered to maintain a smooth path to the skin tissue. It plays a role of ensuring smooth mobility of the first chamber 10.

Additionally, the guide groove 140 may include a plurality of sub-guide grooves 141 recessed and extended outwardly at regular intervals along the longitudinal direction on the left and right sides thereof.

That is, the sub-guide groove 141 refers to an additional recessed groove formed on both left and right sides around the guide groove 140, like a thorn of a fish, and the sub-guide groove 141 is a first Since the thread 10 is not covered, it may have a space containing external air. Through this air, the first thread 10 is in close contact with the guide groove 140 and is not pushed out to the skin tissue during the treatment of the rest of the practitioner. It plays a role in preventing problems that do not occur.

In other words, if the first thread 10 is pressed or adhered to the bottom of the guide groove 140, there is a problem that it is not easily separated from the guide groove 140 in the process of tying, and the first thread 10 is forcibly directed toward the skin tissue. ), the first thread 10 may be broken or deformed, and sub-guide grooves 141, which are spaces that can contain air, are additionally provided around both sides of the guide groove 140. Thus, an air layer is formed between the region around the guide groove 140 and the first seal 10, so that the first seal 10 is placed on or around the guide groove 140 by a cushioning action such as a cushion and a repulsion of the air layer. Unnecessarily sticking to the problem can be avoided.

7 is a conceptual diagram showing a modified embodiment of a bent portion of a first thread and a second thread in contact therewith.

As described above, the second thread 20 is inserted into the space between the first thread 10 that occurs inside the bent portion and wraps around the outer circumferential surface of the needle 100 in a spiral shape starting from this point. If the viewpoint is not properly fixed inside the bent portion of the first thread 10 and is pushed or slipped, the second thread 20 is idle or rotated when the second thread 20 is wound around the needle 100 to form a spiral shape. Can follow.

In order to prevent this, a coupling groove 12 is formed on the inner surface of the bent portion of the first thread 10, and a portion of the second thread 20 is inserted into the coupling groove 12, and the above-described sliding. You can avoid the problem.

That is, the coupling groove 12 accommodates and fixes a portion of the second thread 10, thereby preventing frequent slipping of the second thread 20 in the first thread 10, and , Thereby, a portion of the second thread 20 accommodated in the coupling groove 12 serves as a stably fixed fixing point, and the second thread 20 forms a helical shape without idling around it. The outer circumferential surface can be wound stably.

Additionally, a plurality of fine protrusions 13 are formed on the inner circumferential surface of the above-described coupling groove 12 at regular intervals, and correspondingly, the surface of a portion of the second thread 20 inserted into the coupling groove 12 Also, it is possible to form a plurality of fine protrusions 22 at regular intervals.

The coupling groove 12 and the fine protrusions 13 and 22 of the second thread 20 provide a role of generating a constant friction force so as to minimize a sliding phenomenon when contacting the two.

In other words, the second thread 20 inserted into the coupling groove 12 by generating a constant frictional force while the fine protrusions 13 and 22 located in the second thread 2 inserted into the coupling groove 12 contact each other. While preventing this slipping phenomenon more reliably, it is possible to fulfill the role of a fixing point for fixing the second thread in the engaging groove 12 as described above.

In summary, when the coupling groove 12 and the fine protrusions 13 and 22 are rotated to form a helical shape while the second thread 20 is inserted into the space inside the bent portion of the first thread 10, the first thread By preventing idle or idle while sliding in the space inside the bent portion of (10), as a result, it is possible to have a foundation for forming a spiral shape for the second thread 20 more smoothly and easily. Provides.
