The tubular portion 200 may be provided with an inclined cutout 210 so that the plumbing moved to the pipeline may be drawn out.

The inclined incision 210 is formed by cutting a predetermined length toward the inside from the tip of the tubular portion 200, the horizontal portion 211 which is cut horizontally at the same or lower point than the axis center of the tubular portion 200, Consisting of the inclined portion 212 connected to the outer surface of the tubular portion 200 inclined successively upward in such a horizontal portion 211.

Here, the reason why the horizontal portion 211 of the inclined cutout 210 is formed equal to or lower than the axis center of the tubular portion 200 is because the main line located in the conduit is connected to the tubular portion 200 through the inclined cutout 210. This is to facilitate the discharge to the outside.

In addition, the inclined portion 212 may be formed to be inclined at a predetermined angle, which, if necessary, withdraws the curved line from the inclined cutout 210 to the rear of the handle portion 100 before inserting the continuous injection rod under the skin. By bending and fixing and then performing the procedure, when performing the stapling to remain in a V-shape under the skin, the slanted portion when the stapling drawn out to the outside through the inclined incision 210 is bent backward toward the handle part 100. By preventing the bent sharply bent due to (212), while preventing the damage of the bent at the same time as the bent to the rear as close as possible to the surface of the tubular portion 200, the front end and the stagnation of the tubular portion 200 When inserted into this subcutaneous line, the trunk line can be inserted smoothly into the subcutaneous line.

On the other hand, the inclined portion 212 of the inclined incision 210 may be configured in a straight form, but in another embodiment configured to be curved in the form of a gentle curve, the tubular portion 200 in the subcutaneous tissue has a minimum resistance Can be moved while receiving.

In another embodiment, the inclined portion 212 is formed with a guide groove at one portion, preferably, an upper center thereof, and thus, when the curved line is bent backward so that the curved line remains subcutaneously in a V shape, the curved line is connected to the guide groove. It may be configured to prevent unnecessary flow of the staircase line for the procedure and the staircase close to the tubular portion 200 as close as possible.

The tip of the tubular portion 200 assists the subcutaneous insertion of the plumbing injecting rod, so that the plumb line passing through the pipe of the tubular portion 200 can easily escape to the outside of the tubular portion 200 through the inclined incision 210. help.

As illustrated in FIGS. 1 and 2, the front end of the tubular part 200 is formed of a spherical round part 220 having an outer surface formed of a front surface, both sides, and a bottom surface thereof, and an inner surface facing the spherical round part 220. As it is composed of the spherical portion 221, the main line exited through the conduit of the tubular portion 200 is able to exit the inclined incision 210 without being caught naturally by the guide of the spherical portion 221.

Here, the spherical portion 221 is a straight inclined surface portion so as to more effectively exit the inclined incision 210 while maintaining a straight line without bending the center line of the spherical portion 221 as shown in FIG. 221a may be formed.

The treatment of the meditation using such a rod injection rod may be performed through a process as shown in FIGS. 6A to 6E.

That is, by inserting the staircase in the tubular portion 200, the end of the staircase is visible through the inclined incision 210, but avoid the tubular portion 200 as shown in FIG. Insert into
