Hereinafter, the configuration and operation according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

This is intended to provide a detailed description so that a person skilled in the art of the present invention can easily practice the contents of the present invention, and does not mean that the technical idea and scope of the present invention are limited. .

In addition, when adding reference numerals to components in each drawing, it should be noted that the same components are indicated with the same reference numerals as much as possible even if they are shown in different drawings, taking into account the configuration and operation of the present invention. Therefore, specially defined terms may vary depending on the intention or custom of the user or operator, and the definitions of these terms should be judged based on the content throughout this specification.

First, the configuration of the wire injection rod, which is easy to manufacture according to an embodiment of the present invention, largely consists of a handle part, a tube body part whose tip is formed as a spherical round part and provided with an inclined cut part, and a tube body part installed inside the tip of the tube body through the inclined cut part. It can be divided into wedges, and each configuration will be looked at in more detail with reference to the illustrated drawings below.

First, the handle portion 100 is,

As illustrated in Figures 1 and 3, the part that the operator holds is cylindrical and a space is formed on one side, and on the other side, one side of the tube body 200, which will be described later, is installed to penetrate the interior of the tube body 200 and the space. Wealth is connected to each other.

The tube portion 200 is,

As illustrated in Figures 1 to 3, the tip is inserted into the subcutaneous tissue in the form of an injection needle with a duct inside, and a line is located in the duct to guide the line into the subcutaneous tissue.

As one side of the tube body 200 passes through the handle part 100 and is connected to the space provided in the handle part 100, the wire input into the space can move along the conduit of the tube body 200. there is.

Here, the thread can be a suture, and the material can be polydioxanone (PDO), glycolide-caprolactone copolymer (PGCL), polyglycolic acid (PGA), glycolide-lactide copolymer (PGLA) alone or A mixture of two or more of the above materials is mainly used, and is used in monofilament and multifilament shapes, and thorn wire is manufactured by post-processing monofilament.

Meanwhile, the tube body portion 200 may be composed of a spherical round portion 220 that is approximately cone-shaped so that the tip of one side facing the handle portion 100 can be easily inserted into the subcutaneous tissue.

In addition, an inclined cut part 210 may be formed in the tube body part 200 so that the wire moved along the pipe can escape to the outside, and this inclined cut part 210 is formed in the tube part 200 to the handle part 100. ) can be formed near the tip of one side opposite to the

The inclined cut part 210 formed in the tube body 200 may be configured with a predetermined width and length, and the formation position of the inclined cut part 210 is at a point equal to or lower than the axial center of the tube body 200. Formed, the inclined cut portion 210 is connected to the horizontal portion 211 cut in a horizontal state and the outer surface of the tube body portion 200 in an upwardly inclined manner at both ends of the horizontal portion 211, forming a substantially arched shape. It may be composed of a first inclined portion 212 and a second inclined portion 213.

Here, the reason why the slanted cutout 210 is formed at a position equal to or lower than the axial center of the tube body 200 is to allow the line to be easily drawn out from the slanted cutout 210.

And the reason why the first inclined portion 212 is formed to be inclined at an obtuse angle with respect to the horizontal portion 211 is when the line located inside the inclined cut portion 210 protrudes to the outside of the inclined cut portion 210. It is lifted, and this is to ensure that it does not interfere with the angle of the first inclined portion 212 and can be sufficiently lifted without damage.

In addition, it is preferable that the second inclined portion 213 is symmetrical with the first inclined portion 212 and inclined to form an obtuse angle, which is achieved by inserting a wedge 300, which will be described later, into the tip of the tube body 200. This is to prevent interference by the second inclined portion 213 when inserting.

In addition, the first and second inclined portions 212 and 213 of the inclined cut portion 210 may be configured in a straight shape, but may also be configured to be curved in a shape that is depressed inward.

Meanwhile, as another example, the wire may be withdrawn through the inclined incision 210 and then bent toward the handle unit 100 and inserted under the skin while the wire injection rod is fixed. In this case, the upper side of the first inclined part 212 If a guide groove is formed along the upper surface of the tube body 200 at this point, when the wire drawn out through the inclined cut part 210 is bent toward the handle part 100, the wire is inserted into the guide groove, so the wire is unnecessary. It is possible to prevent flow and has the effect of allowing the wire to adhere to the surface of the tube body 200 as closely as possible.

The wedge (300) is

As illustrated in Figures 1 to 3, it is installed inside the tip of one side opposite to the handle part 100 in the above-described tube body part 200 to guide the wire to be naturally drawn outward through the inclined cut part 210. It plays a role.

The wedge 300 is accommodated inside the tip of one side of the tube portion 200, and one side of the wedge 300 is in close contact with the inside of the tip, and the other side is configured not to protrude more than necessary toward the inclined cut portion 200. It may be, and in this case, the other surface may be composed of an inclined surface 310 having an angle corresponding to the inclination angle of the second inclined portion 213.

Accordingly, the line moving to the inclined cutout 210 through the tube portion 200 can be easily drawn out of the inclined cutout 210 by touching the inclined surface 310 of the wedge 300.

On the other hand, the wedge 300 is fixed to the inside of one end of the tube body 200 through the inclined cut part 210, for example, by force fitting the wedge 300 to the inside of one end of the tube body 200. It can be fixed in this way.

As another example, a small amount of adhesive such as epoxy is injected into the tip of one side of the pipe portion 200, and the wedge 300 can be inserted into the tip of one side to secure the wedge 300 inside the tip through the adhesive. there is.

In addition, as another example, in a state where the wedge 300 is installed inside one end of the tube body 200, the outer circumference of the inclined surface 310 of the wedge 300 and the one end in contact with the outer circumference of the inclined surface 310 The wedge 300 may be fixed by welding the inner surfaces together.

In the surgical method using the wire injection rod configured in this way, for example, the end of the wire that moves the pipe of the tubular body 200 through the handle part 100 is positioned in the inclined incision 210. By inserting a wire fixture into the space of the handle unit 100, the movement of the wire located in the conduit of the tube body unit 200 can be fixed.

Then, when the needle injection rod is inserted subcutaneously and the needle wire is pushed in approximately 5 to 10 mm by hand with the needle wire fixture removed, the end of the needle is pushed along the inclined surface 310 of the wedge 300 and outside the incision slope 210. It comes out to some extent.

In this state, the operator, considering the position of the end of the line, presses the area on the skin surface that corresponds to the position of the end of the line with the hand, then separates the line injection rod from the subcutaneous area, and the line remains in a straight shape under the skin. It will exist.

In this way, by inserting the line under the skin in a straight line, a uniform line effect can be obtained. It can be used when expecting an accurate and uniform effect in areas with relatively few wrinkles, and when inserting the line injection rod under the skin, It has the advantage of reducing line resistance and interference.

In addition, when installing the wire on the wire injection rod, the wire injection rod is easier to use compared to the surgical method of pulling out the wire from the incision slope 210, bending it backward, and then fixing it using parts such as a silicone fixture. The effect can be improved.

Meanwhile, the wire injection rod according to an embodiment of the present invention can be manufactured through the following manufacturing method, as illustrated in FIG. 4.

That is, the preparation step of the tubular body (P) having a cylindrical shape and a hollow portion inside may be performed first, and at this time, the tubular body (P) is in a state where both sides are open.

In the next step, although omitted in the drawing, a step may be performed in which the handle portion 100 is connected to the other side of the pipe body (P). Accordingly, the internal space of the handle portion 100 is a pipe that is a hollow part of the pipe body (P). The line inserted through the space of the handle portion 100 while communicating with can be moved along the conduit of the pipe body (P).

And the next step may be to compress the open inlet at one end of the tube body (P) opposite to the handle portion 100 into a cone shape that gradually becomes narrower toward the end.

Here, it is preferable that the compressed end point is located on the same line as the axial center of the pipe body (P).

In the next step, the outer surface of one end compressed from the pipe body P is welded to completely close it, and then the outer surface is treated smoothly.

At this time, the outer surface can be formed into a spherical round part 220 forming a cone shape by processing it smoothly through sanding, etc. while maintaining the closed state.

The next step is to form a slanted incision 210 in the spherical round part 220 on the surface of one end of the tube body P. Through this step, the tube body P is formed into the tube body part 200. ) can be.

Here, the inclined cut part 210 can be made through processing such as cutting, and the interior can be opened by cutting a part of the surface of the tube body (P), but the horizontal part 211 processed horizontally is the tube body part. It is preferable to be configured to be the same as the axial center of (200) or to be located below the axial center, and on both sides of the horizontal portion 211, a first slope is formed in a substantially arcuate shape toward the outer surface of the tube portion 200. The portion 212 and the second inclined portion 213 may each be formed to be inclined.

In addition, it is preferable that the first inclined portion 212 and the second inclined portion 213 are each configured to form an obtuse angle with respect to the horizontal portion 211. In this case, the first inclined portion 212 and the second inclined portion 213 ) are preferably configured to face each other and be symmetrical.

The next step may be to install the wedge 300 into the spherical round part 220 through the inclined cut part 210 formed in the tube part 200.

One side of the wedge 300 inserted into the spherical round portion 220 is in close contact with the inner surface of the spherical round portion 220, and the other side is an inclined surface 310 having an inclination angle corresponding to the second inclined portion 213. ), and in this case, the inclined surface 310 is preferably configured to not protrude beyond the line of the second inclined portion 213, to be the same as the line, or to slightly protrude even if it protrudes beyond the line.

Fixing the wedge inside the spherical round part 220 configures the shape of one side of the wedge 300 to correspond to the internal shape of the spherical round part 220 and adjusts the size of the outer shape so that one side of the wedge 300 is It can be configured to be firmly fixed while being press-fitted into the inside of the spherical round part 220.

The fixing of the wedge to the inside of the spherical round part 220 is done in another way by inserting a small amount of adhesive into the inside of the spherical round part 200 and pushing it to one side of the wedge 300 to form the spherical round part 220 through the adhesive. It can also be configured to be glued to the inside of the.

Fixing the wedge inside the spherical round part 220 is another method. After inserting the wedge 300 into the spherical round part 220, the inclined surface 310 of the wedge 300 and the spherical round part ( 220) can also be fixed by welding the inner surfaces together.

Meanwhile, in the manufacture of the wire injection rod according to the present invention in another embodiment, as illustrated in FIG. 5, a hollow portion is first formed in a cylindrical shape, and one end is blocked, and the diameter gradually decreases toward the end to form an approximately conical shape. It is formed as a spherical round part 220, and the tubular body (P-1) forming step may be performed first with the other end having an open inlet.

Thereafter, the step of installing the wedge 300 into the spherical round part 220 of the tube body 200 through the inclined cut part 210 is performed, and a wire injection rod may be manufactured.

In this manufacturing method, since one end of the pipe body (P-1) is pre-molded into a spherical round part 220 without any additional processing, the step of pressing or surface treatment of one end of the pipe body (P-1) is omitted. This has the advantage of being able to shorten the manufacturing time and simplify manufacturing.

In addition, in another embodiment of the above-mentioned wire injection rod manufacturing, a wedge 300 is installed inside the spherical round part 220 of the tube body 200 through the inclined cut part 210 formed in the tube body 200.
