Description
KNOTLESS SUTURE, AND KIT CONTAINING SAME
TECHNICAL FIELD
The present invention relates to a suture used for a surgical operation, and more
particularly, to a suture that does not require a knot tying operation and is able to be
firmly and stably sutured or to tightly support and fix tissues.
BACKGROUND
A suture has been used for a long time to be used to connect and suture damaged
muscles, blood vessels, nerves, or tissues and injuries or parts incised due to a surgical
operation. In addition, a suture is used for a double eyelid surgery and a medical
operation for removing tissues, which are generated due to aging, a decrease in skin
elasticity, injuries, overdose, necrosis, or the like, a flabby skin, wrinkles, or the like.
A lifting medical operation using a suture is a technology to lift up a flabby skin or
tissue such as a face, a chin, a neck, an abdomen, a vagina, a breast, or a hip by using
needles and threads instead of using a knife. The lifting medical operation using a
suture has attracted much attention because the lifting medical operation does not
excessively incise a skin, minimizes generation of scars, and generates less bleeding
and swelling due to an operation.
[0003] Recently, a suture in which barbs are formed on an external surface thereof has
been developed and used. Such a suture is not slipped due to the barbs, and thus the
suture is not easily untied after a sutura.
One of points to be considered in an operation using a suture that is firmly
maintained and fixed at a part where a surgical operation has been performed, in order
to stably maintain suturing and tight adhesion, supporting, and fixing of tissues. In
addition, a firm knotting device for allowing a suture not to be untied is required, and
also it is necessary to minimize time and efforts on knotting for a rapid and safe
operation.
The inventors of the present invention applied for Korean Patent Application
Nos. 100019895 and 100064084 for a suture including a suture supporter
not requiring a knotting process, and the contents thereof are introduced in the present
specification. The inventors of the present invention have conducted the study in order
to invent a more convenient and useful suture.

DETAILED DESCRIPTION
Embodiments will now be described more fully with reference to the
accompanying drawings, in which exemplary embodiments of the invention are shown.
The invention may, however, be embodied in many different forms, and should not be
construed as being limited to the embodiments set forth herein; rather, these
embodiments are provided so that this disclosure will be thorough and complete, and
will fully convey the concept of the invention to one of ordinary skill in the art. In the
drawings, the parts of the needle, suture supporter and barbs are exaggerated for clarity.
is a view showing a suture supporter 20 according to some embodiments.
The suture supporter 20 has a truncated conical shape or a truncated pyramid shape.
The suture supporter 20 includes a communication hole 25 through which upper and
lower end portions communicate with each other, and a diameter of the communication
hole 25 is larger than that of a suture (see A)).
The suture supporter 20 according to some embodiments may include one or
more cut portions 23 that are cut in a longitudinal direction from a lower end portion 22
of the lower portion having a relatively larger diameter from among the upper and
lower end portions (see B)). Alternatively, a part of the lower portion is
removed so as to form one or more gaps 24 formed from the lower end portion in a
wall of the lower end portion (see FIGS. 1(C) and 1(D)). A length of the cut portion
23 and a size or shape of the gap 24 may be appropriately adjusted according to parts
and purposes to use a suture.
The suture supporter 20 according to some embodiments may be formed of a
material not absorbed into a body or an absorbable material according to purposes.
For example, the suture supporter 20 may be formed of nylon, polypropylene (for example,
MESH), polyvinyliden fluoride, polyester, stainless steel, gold, titanium, silicon, medpore,
gore-tex, mesh, polylactic acid, polydioxanone (PDO, PDS), or copolymer of lactic acid and
glycolic acid, but the present invention is not limited thereto. If the suture supporter 20 is
formed of an absorbable material, it is not necessary to remove the suture supporter 20 after
performing a sutura of an inner part of the body.
The length of the suture supporter 20 according to some embodiments may be, for
example, about 1 to about 10 mm. However, the present invention is not limited thereto,
and thus the length of the suture supporter 20 may be adjusted according to parts and
purposes to use the suture supporter 20.
From among holes of both ends portions of the suture supporter 20, a diameter of a relatively
smaller hole is, for example, about 0.1 to about 2 mm, and a diameter of a relatively larger
hole is, for example, about 0.5 to 5 mm. However, the present invention is not limited
thereto, and the diameters of the holes may be adjusted according to thicknesses of a suture
and purposes to use the suture.
As an embodiment of the present invention, when the suture supporter 20 has a
truncated conical shape or a truncated pyramid shape and includes the communication hole
and when a suture has first and second ends, the suture supporter 20 is connected to the
first end, and the suture may have barbs. The suture supporter 20 may include one or more
cut portions 23 that are cut in a longitudinal direction from the lower end portion 22 of the
lower portion having a relatively larger diameter from among the upper and lower end
portions (see B)), or a part of the lower portion is removed so as to form one or more
gaps 24 formed from the lower end portion in a wall of the lower portion 22 (see FIGS. 1(C)
and 1(D)).
The method includes a step of coupling the suture to the suture supporter 20 through
the communication hole 25 so that an upper end portion 21 of the upper end having a
relatively smaller diameter from among both the upper and lower ends of the suture supporter
faces the first end 11, and a step of forming a knot 50, which has a diameter larger than
that of a hole of the upper end portion 21 of the suture supporter 20, between the first end 11
of the suture and the upper end portion 21 of the suture supporter 20 and forming an
agglomerated portion of the suture by applying heat thereto, so that the suture supporter 20 is
not separated from the suture. However, the present invention is not limited thereto.
According to an embodiment of the present invention, in the suture of the present
invention, the other end portion not connected to the suture supporter 20, that is, the second
end 12, may be used in a state coupled or uncoupled to a needle. Here, the needle used is
manufactured of an non-absorbable material such as a metal material, or an absorbable
material (for example, polylactic acid). The needle for a sutura may be formed in the shape
of a straight line or a curve, and a point of the needle may have a shape that is widely used
such as a rounded shape, a cut shape, or an extended shape.
Examples of a method of coupling a suture to a needle may include a method of
inserting the suture into a hollow needle body and pressing the needle, a method of forming a
hole (needle's eye) in the needle and inserting the suture into the hole, and the like.
However, the present invention is not limited thereto, and various other methods may be
used.
is a view showing the suture including the first and second ends 11 and 12. In
the suture, the suture supporter 20 has a truncated conical shape or a truncated pyramid shape
and includes the communication hole 25 through which upper and lower end portions
communicate with each other. The suture supporter 20 having cut portions or gaps at the
lower end portion thereof is disposed at the first end 11 so that an upper end portion of the
suture supporter 20 (the upper end portion 21 having a relatively smaller diameter from
among the upper and lower end portions 21 and 22) faces the first end 11 of the suture
connected to the suture supporter 20, and a needle 30 is disposed at the second end.
Barbs are formed on a surface of the suture so that angles between a longitudinal axis
of the suture and the barbs are inclined in the same direction. The barbs are formed on the
surface of the suture to be inclined so that an angle 0 formed by the longitudinal axis of the
suture and the barbs disposed at the second end of the suture is an acute angle. As such, if
the barbs are formed so that the angle between the barbs and the suture has a pointed shape
toward the second end of the suture not including the suture supporter 20, the suture may
smoothly pass through a tissue when performing a sutura using the needle coupled to the
second end of the suture. However, even if the needle is removed from the second end of
the suture after the sutura, if the suture intends to move in a direction opposite to a direction
of the sutura, the barbs may serve as a support to prevent the movement of the suture. Even
though the needle is cut after the sutura, the suture is not pulled out, and thus it is not
necessary to make a knot. In addition, the suture supporter 20 disposed at one end of the
suture may serve as a knot that allows the suture not to be untied and may tightly fix the
suture supporter 20 so that the suture supporter 20 does not move due to the cut portions or
the gaps formed in the lower portion of the suture supporter 20 when pulling the suture while
performing a sutura or lifting. Accordingly, the suture supporter 20 may stably maintain a
lifting effect for a long time.
According to an embodiment of the present invention, one or more sutures including
barbs may be used, and a number of sutures may be appropriately adjusted according to
thicknesses of the sutures or purposes to use the sutures. Each suture may be a single suture
or a multi suture that is twisted or woven. Here, the first end of each suture including barbs
may be coupled to one suture supporter 20 (see FIGS. 2(B), 2(C), 2(E), and 2(F)), or
alternatively, the first end of each suture may include a separate suture supporter (see D)). In addition, second ends of two sutures may be coupled to one needle (see FIGS.
2(B), 2(C), 2(D), and 2(E)), or alternatively, different needles may be coupled to the seconds
of two sutures, respectively (see F)).
B) shows two or more sutures in which front barbs and rear barbs are formed to
be inclined in the same direction. In B), one end parts of the suture are coupled to a
needle and the other end parts thereof are coupled to the suture supporter 20. Here, the
barbs are disposed to be inclined so that the angle 0 formed by the longitudinal axis of the
suture and the barbs disposed at the end part of the suture coupled to the needle is an acute
angle. C) shows another embodiment in which one or more sutures are folded in half
and then both ends are coupled to the suture supporter 20 and the needle. In C), the
suture is formed so that front barbs and rear barbs formed in the suture are inclined in an
opposite direction (for example, so that an angle between the front barbs and the longitudinal
axis of the suture is less than 90° and the front barbs are inclined toward a front end of the
suture and so that an angle between the rear barbs and the longitudinal axis of the suture is
less than less than 90° and the rear barbs are inclined toward a rear end of the suture).
shows a suture to which the suture supporter 20 is coupled which includes a
communication hole through which upper and lower end portions communicate with each
other and has a truncated conical shape or a truncated pyramid shape or the suture supporter
is coupled which includes a communication hole through which upper and lower end
portions communicate with each other, has a truncated conical shape or a truncated pyramid
shape, and has cut portions or gaps at a lower end portion of the suture supporter 20. The
suture supporter 20 is coupled to the suture via the communication hole to be disposed at the
first end 11 so that the upper end portion 21 (end portion having a relatively smaller diameter
from upper and lower end portions) of the suture supporter 20 faces the first end 11 of the
suture, and the needle is not disposed at the second end 12. The suture may include barbs
on a surface thereof, and the barbs may be formed to be inclined toward the second end of the
suture so that an angle 0 formed by the longitudinal axis of the suture and the barbs is an
acute angle.
According to an embodiment of the present invention, one or more sutures including
barbs may be used, and a number of sutures may be appropriately adjusted according to
thicknesses of the sutures or purposes to use the sutures. When two or more sutures are
used, the sutures may pass through a communication hole of one suture supporter 20 to make
a knot (see FIGS. 3(B) and 3(C)), or alternatively, one suture is coupled to the suture
supporter 20 to pass through the communication hole of the suture supporter 20 (see D)). FIGS. 3(C), 3(D), and 3(E) show an example in which one or more sutures, which
are formed so that front barbs and rear barbs are inclined in an opposite direction, are folded
in half and then one end of the suture is coupled to the suture supporter 20.
A suture including barbs is disclosed in Korean Patent Publication Nos.
100039345 and 100108494, Korean Utility Model No. 20-320005, US Patent
No. 5931855, and the like, and the contents are introduced in the present specification.
Barbs may be arranged on a fiber according to any necessary configurations, and may be
formed by using any appropriate methods including methods well-known in the art. Those
methods may include injection molding using a knife, a laser, or press molding, stamping,
and cutting. A necessary number of portions cut at an acute angle are formed in a suture.
A size of barb may be appropriately adjusted according to purposes within the bounds of a
common sense in the art. For example, a depth of the barb formed in the suture may be
about 30 to 100 micron and may be adjusted according to a diameter of the suture. An
interval between barbs formed on a surface of the suture may be about 100 micron to 1 mm
or more.
The suture used in the present invention may be formed of, for example, a polymeric
material, a metal material, a biological material, or the like. The suture may be formed of a
non-adsorbable material, for example, polypropylene, gold, stainless steel, titanium, nylon,
polyvinyliden fluoride, polyester, or braided silk, or an adsorbable material, for example,
polydioxanone (PDO, PDS). However, the present invention is not limited thereto. In
addition, the suture used in the present invention may be formed into a short fiber shape or a
twisted shape.
Hereinafter, description will be given of a method of using a suture 10 including the
suture supporter 20 at one end thereof, wherein the suture supporter 20 may include a
communication hole through which upper and lower end portions communicate with each
other and has a truncated conical shape or a truncated pyramid shape or may include cut
portions or gaps at a lower end portion thereof and has a truncated conical shape or a
truncated pyramid shape. The method may include the following processes.
1) a step of piercing a skin or a tissue using a needle so that a suture supporter is
located in a predetermined position of the skin or the tissue and pushing a hollow pipe in the
predetermined position of the skin or the tissue,
a step of inserting the suture 10 including the suture supporter 20 according to
an embodiment of the present invention into the pipe so that the suture supporter 20 reaches
the predetermined position,
3) a step pressing the suture supporter 20 having passed through the pipe inside
the skin or the tissue from the outside, fixing the suture supporter 20 using a thin bar so as not
to move, and removing only the pipe, and
4) a step of pushing the skin or the tissue while pressing the suture supporter 20
and pulling the suture.
Here, one or a plurality of sutures may be used in which a line of barbs are formed
and includes the suture supporter 20 at one end thereof. Alternatively, the suture used here
may be a suture in which two or more lines of barbs are formed may be coupled to one suture
supporter 20. In the above-described method, the suture supporter 20 may serve as a knot
that allows the suture not to be untied and may also allow the suture not to move and be fixed
when puling the suture while performing a sutura or lifting. The suture supporter 20 having
the cut portions or the gaps formed at the lower end portion thereof may further firmly fix the
suture, and thus the suture supporter 20 may stably maintain a lifting effect for a long time.
When the barbs are formed to be inclined toward the second end so that the angle 0
formed by the longitudinal axis of the suture and the barbs disposed at the second end of the
suture is an acute angle, the formed barbs may prevent the suture from being pulled out in a
direction opposite to the lifting by an angle between the barbs and a surface of the suture and
may maintain a tissue in a pulled state. When inserting the suture into a long pipe,
resistance against the tissue does not exist, and thus the suture may easily pass through the
long pipe. In addition, even when removing the long pipe and pushing the tissue while
pressing the suture supporter 20 and pulling the suture, the barbs formed such that an angle
between the barbs and the suture is an acute angle do not greatly affect movement of the
tissue, but if the tissue intends to return in an opposite direction, the barbs resist.
An embodiment of the present invention provides a device capable of easily
performing an operation by using the suture provided in the present invention. The device
provided in the present invention includes a kit (kit A) equipped with a suture and a suture
positioning kit (kit B) for allowing a suture to be accurately positioned in a tissue.
The kit (kit A) equipped with a suture includes a hollow pipe 70 in which a hole
through which both end portions communicate with each other is formed, and the suture
installed in the hollow pipe 70. The suture has first and second ends, and the suture
supporter 20 is disposed at the first end of the suture. The suture supporter 20 may have a
truncated conical shape or a truncated pyramid shape and may have a communication hole
through which upper and lower end portions communicate with each other. Alternatively,
the suture supporter 20 may have a truncated conical shape or a truncated pyramid shape,
may have a communication hole through which upper and lower end portions communicate
with each other, and cut portions or gaps may be formed at the lower end portion thereof.
The suture supporter 20 is coupled to the suture via the communication hole to be disposed at
the first end of the suture so that the upper end portion of the suture supporter 20 faces the
first end of the suture. The suture may include barbs on a surface thereof, and the barbs may
be formed to be inclined toward the second end of the suture so that an angle 0 formed by the
longitudinal axis of the suture and the barbs disposed at the second end of the suture is an
acute angle. In the kit A, the suture supporter 20 provided in the present invention is
disposed in the hollow pipe 70 in which both end parts communicate with each other, and a
suture including barbs on a surface thereof is inserted into the hollow pipe 70. Here, the
suture supporter 20 is positioned at an end of the suture pierced into a tissue from among the
both ends of the suture (see A)). The suture supporter 20 may be positioned inside
the hollow pipe 70 or outside of the end part of the hollow pipe 70, or may be positioned
across the inside and the outside of the hollow pipe 70, when necessary. In the kit A, the
communication hole of the hollow pipe 70 may have a diameter capable of accommodating
the suture, and the diameter may be adjusted according to purposes.
The suture positioning kit (kit B) for allowing a suture to be accurately positioned in a
tissue includes a hollow pipe 80 in which a communication hole through which both end
portions communicate with each other is formed, and a rod 90 that is inserted into the
communication hole of the hollow pipe 80, is formed to be longer than the hollow pipe 80,
and has a pointed tip capable of being inserted into a body an one side thereof (see B)).
The rod 90 is formed of a material having strength to be pierced into a skin or a tissue, and if
the pointed tip of the rod 90 has a blunt shape or a rounded shape, the damages of the tissue
may be minimized.
The hollow pipe 80 of the kit B is shorter than the hollow pipe 70 of the kit A, and
may have a diameter of the communication hole larger than that of the kit A so as to
accommodate the kit A. The hollow pipe and the rod may be formed of any material that
has a high hardness to be pierced into a metal or a tissue and is harmless to humans, for
example, urethane or plastic. The hollow pipe 70 of the kit A and the hollow pipe 80 of the
kit B may be provided with a handle at an end part thereof for convenience of an operation.
The device shown in may be used by using a method including the following
processes.
1) a step of pushing the kit B into a portion or a tissue to be sutured or lifted,
2)
a step of removing only the rod 90 and leaving the hollow pipe 80,
3) a step of pushing the kit A into the hollow pipe 80 remaining in a tissue (here,
a portion at which the suture supporter 20 is positioned is allowed to face the inside of the
tissue),
4) a step of removing the hollow pipe 80 of the kit B and leaving the kit A in the
tissue.
) a step of pushing the suture supporter 20 using a thin bar into the tissue
outside of the hollow pipe 70 of the kit A,
6) a step of removing the hollow pipe 70 of the kit A and the thin bar, and
a step pushing a skin (or outside of tissue) toward the suture supporter 20
while pulling a suture. If necessary, it is possible to allow the suture supporter 20 not to
move by pushing the suture supporter 20 from the outside (for example, skin).
The present invention also provides a kit that facilitates an operation using the suture
provided in the present invention (see . The kit includes: i) a hollow pipe 104
including a front end provided with a tip 101 that is formed to be tapered, a rear end provided
with a handle 103, and an accommodation portion 102 accommodating the suture supporter
disposed in a suture around the front end and capable of being separated in a direction of a
longitudinal axis connecting the front end and the rear end; and ii) the suture including the
suture supporter 20 that is installed in the hollow pipe 104 and is provided in the present
invention. A) shows the hollow pipe 104 in which the suture including the suture
supporter 20 is disposed.
[0038]Here, a tip of the front end of the hollow pipe 104 may be closed, or alternatively, a
hole may be formed in the front end of the hollow pipe 104 to communicate with the rear end.
The tip may be formed of a material having strength to pierce a tissue. If the tip is formed
to be rounded, the damage of the tissue may be reduced. The accommodation portion 102
formed in the hollow pipe 104 is formed to extend from the front end portion and is a space
capable of accommodating the suture supporter 20 disposed in the suture. A size and shape
of the accommodation portion 102 may be appropriately adjusted according to a size and a
number of the suture supporter 20 accommodated in the accommodation portion 102 (see
FIGS. 5(B)).
The hollow pipe 104 may be separated in a direction along a longitudinal axis
connecting the front end and the rear end as shown in . The hollow pipe 104 may
be formed by placing the suture including the suture supporter 20 on one half portion 104b of
the separated hollow pipe 104 and covering the other half portion 104a on the suture. Here,
for example, a convex portion 105 may be formed in one of a half handle 103a and a half
handle 103b at the junction of the half handle 103a and the half handle 103b, and a concave
portion 106 may be formed in the other one of the half handle 103a and the half handle 103b
at the junction of the half handle 103a and the half handle 103b, so that the half handle 103a
and the half handle 103b may be stably fixed when coupling the half handle 103a and the half
handle 103b to each other, thereby stably maintaining the hollow pipe 104 accommodating
the suture (see D) which is a top view of the handle 103). In addition, various
methods may be performed of allowing the hollow pipe 104 formed by coupling separated
two parts to each other to stably maintain its shape until a necessary time during an operation.
An operation may also be performed by using a method of pushing the hollow pipe
104 accommodating the suture into a part to be sutured or lifted from the tip 101, inserting a
thin bar through a space of the hollow pipe 104 so as not to move the suture supporter 20,
separating the hollow pipe 104 to sequentially remove the separated half portions 104a and
104b, and pushing a skin (or outside of tissue) toward the suture supporter 20 while pulling
the suture.
The suture provided in the present invention may be used to safely perform an
operation without making a knot when tightly adhering, supporting and fixing tissues to be
sutured. The suture may be firmly maintained and fixed in a part to be sutured and may
effectively holding tissues. In addition, when the kit provided in the present invention is
used, an operation may be easily, simply, and effectively performed regardless of a skill of a
doctor. While the present invention has been particularly shown and described with
reference to exemplary embodiments thereof, it will be understood by those of ordinary skill
in the art that various changes in form and details may be made therein without departing
from the spirit and scope of the present invention as defined by the following claims.
