Hereinafter, with reference to FIG. 5, an example of the method of using the medical seal apparatus according to the present invention will be described.

The medical seal device according to the invention can be used, for example, for lifting sagging skin at the neck.

First, after anesthetizing a part of the skin in which the thread inserting hole 4 is to be formed, it is punctured with a needle or the like. Through the thread insertion hole 4 formed as described above, for example, the

medical thread device

100, 200a, 200b or 300 using the medical thread insertion kit disclosed in Korean Patent Registration No. 10-1326763 (November 08, 2013). Can be inserted into the skin tissue in the direction of arrow A1, A2 or A3 (the detailed description thereof is disclosed in the above patent and is omitted for simplicity). In this case, the medical seal device may be inserted into the skin tissue while the skin tissue is moved by a predetermined amount in a predetermined direction, for example, in a direction opposite to the directions of the arrows A1, A2 and A3. Next, the medical thread inserting device is removed, and the medical thread device is left in the skin tissue while the other ends 16 and 26 or the

extensions

10a and 20a of the medical thread insert are left outside of the thread inserting opening 4. Lose.

The medical thread 20 provided with the cone 30 and the barb 22 formed in the forward direction is pulled from the outside to be caught by the skin tissue, and the skin on the medical thread may be lowered downward so that it is not bumpy. The medical chamber 10 provided with the barb 12 formed in the opposite direction to the cone 30 is slightly pulled out to prevent the tissue and the cone from falling down. Finally, the

medical seals

10 and 20 that come out of the skin are cut with scissors or the like.

In the case of the medical seal device 100 inserted into the skin tissue as described above, the forward barb 22 of the medical seal 20 exerts or supports a force in the same direction as the cone 30, such that the reverse barb 12 The tissue between) can be immobilized.

On the other hand, in the case of the medical seal device of the prior art shown in FIG. 6, the barbs 91 formed in the medical seal connected to the cone 80 by the knot 92 are all reversed, and as shown in FIG. 80 is inserted in the direction of the arrow B through the insertion hole formed in the lower front 4 of the neck and is disposed on the upper side of the neck.

Therefore, as described above, in the lifting treatment method using the medical seal device 100 according to the present invention, the thread insertion hole 4 may be formed on the upper side of the neck, so that the hook member 30 is not easily seen. And since the barb 22 supports the skin tissue, it can exhibit an improved surgical effect. In other words, the seal 20 provided with the forward barb 22 is coupled so that the bearing force on the skin tissue can be acted in the same direction as the bearing action direction of the cone, so that the bearing force for supporting the skin is transmitted through the cone. Tissues with limited movement due to the line 10 through the barbed thread generated in the forward direction to the force centered on) and the thread 10 generated with the reverse barb and the thread 20 generated with the forward barb Since the bearing force of the cone is transmitted to the (surface), the bearing force is improved as compared with the conventional medical seal device.

As another procedure, when the

medical seal device

100, 200a, 200b or 300 according to the invention is used, for example, for lifting the facial skin, the medical seal device is inserted from the top of the face down to the bottom of the cone. The support force acts from the bottom of the face up to the face, supporting it in the direction of lifting the sagging tissue up. On the other hand, in the prior art of Figs. 6 and 7, the lifting effect is higher than the medical seal device of the present invention because the medical seal device inserts a thread from the bottom of the face upward, and thus the bearing force of the cone acts from the top of the face down to the face. not big.

On the other hand, in the medical thread device according to the present invention, when the needle is attached, the

needle

40 or 41 connected to the medical thread that comes out of the skin is inserted into the tissue through the incision site or the suture insert 4. The

needle

40 or 41 and the medical seal are then pulled out of the skin through the tissue in the opposite direction of the cone 30 to pull the barbs out of the tissue. Finally, cut the thread out of the skin with scissors.

In addition, when one of the two medical seals has an

extension portion

10a or 20a, a

reverse thread

17 or 27 is provided in the

extension portion

10a or 20a, and the medical thread provided with the forward barb 12 and It is possible to increase the bearing capacity in the direction opposite to the bearing force generated in the tissue between the medical thread provided with the forward barb and the medical thread provided with the reverse barb. In particular, when the product is inserted from above and below the face, the tissue lifted by the extension where the reverse barbs are generated serves to anchor the tissue so that it does not fall down. In addition, by inserting the extension portion into the skin above the medical thread inserting port, the supporting force of the medical thread can be increased. The needle may be both a straight needle 40 or a curved needle 41, and the needle may be inserted upward or may be sutured to generate a support portion.

In the prior art medical seal device as shown in Figure 6, even if the thread is inserted from the top to the bottom of the face, because the cone (or suture support) is a force that lifts the tissue from the bottom is transmitted only at one point. There is a possibility of dimpling facial tissue. On the other hand, the medical thread device of the present invention has a force for lifting the skin is a point (cone), line (medical thread or suture provided with a forward barb) and cotton (medical thread or suture and a reverse barb provided with a forward barb) The space between the sutures is transmitted to the tissue, thereby reducing the likelihood of recesses.
