The present invention can simply hemostatic the perforated portion of the human blood vessels using a hemostatic plug, and in particular, the hemostatic plug can be inserted at an optimal position for hemostasis of the perforated region, thereby further improving the surgical stability. It relates to a perforated blood vessel closure device using a hemostatic plug to secure the.

Generally, a long, thin tube-shaped catheter is used for various medical procedures through blood vessels of the human body, and the catheter is inserted into a perforated passage between skin tissue and blood vessels to facilitate various medical procedures through blood vessels from the outside. To make it work.

After medical treatment using the catheter, hemostasis of the perforated area of blood vessels should be done quickly. As the hemostatic method, a hemostatic method is used to compress the perforated area of blood vessels of a patient using a hand, a sandbag, or a compression machine. do.

However, the compression method not only takes excessive time for hemostasis, but also requires a lot of constraints on the patient's behavior since the patient must remain stationary during the procedure. In particular, during hemostasis, the perforated region is compressed for a long time, and thus the blood flow is depressed, which is one factor causing medical side effects such as deep vein thrombosis, pulmonary embolization, and hematoma.

Representative hemostatic method that complements the problems of the compression method is a perforated vascular closure method to directly block the inside of the perforated portion of the blood vessels. In the procedure of the perforated vascular closure method, a perforated vascular closure device is used to directly block the perforated portion of the blood vessel using a biodegradable polymer material.

Briefly describing the general structure of the perforated vessel closure device, an anchor of a biodegradable polymer material is located at the end of the tube having an elongated inner passage, and a pull thread is connected to one side of the anchor. The seal extends through the inside of the tube to the opposite end. The anchor is supported by the pulling seal and is in a state capable of switching to a posture parallel to or perpendicular to the tube at the end of the tube.

Then, the hemostatic sponge of collagen is inserted into the tube to prevent the perforation, and the pushing member is positioned above the hemostatic sponge.

Such a perforated vessel closure device has a posture parallel to the tube at the end of the tube and is inserted into the perforation site and then switched to a posture that can be hooked to the inner wall of the vessel at a point inside the vessel. The lower end of the perforated passage is blocked by the anchor and the hemostatic sponge by inserting the hemostatic sponge into the perforated passage by inserting the hemostatic sponge into the perforated passage by using the pushing member. Hemostasis is in progress.

However, the anchor is a structure that supports the hemostatic sponge in a state pulled by the pulling thread inside the perforated blood vessel, so that a part of the anchor is cut or a part of the connection section of the pulling thread is cut by excessive pressure during the procedure. As well as the anchor and the hemostatic sponge can flow into the blood vessel as it is, causing fatal medical accidents.

In addition, when hemostasis progresses while the anchor is connected to the pulling thread and is biodegraded while being positioned inside the perforated blood vessel during the hemostasis time, the anchor is in a state occupying a part of the blood vessel to cause a blood flow disorder inside the blood vessel. In addition, it is difficult to obtain satisfactory procedure reliability because the anchor or pull thread is a factor that causes various side effects such as an inflammatory reaction by contacting the skin tissue of the perforation site.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to simply bleed only the perforated portion of the blood vessels using a hemostatic plug without occupying the inside of the blood vessels, in particular hemostasis The present invention provides a perforated blood vessel closure device using a hemostatic plug that can secure an improved procedure stability by setting a plug for an optimal position.

In order to realize the object of the present invention as described above,
