2. 발명이 해결하려고 하는 기술적 과제2. The technical problem to be solved by the invention
동맥류 등의 혈관질환 환자들의 경우는 고혈압이나 심장병등의 기타원인으로 병변 부위의 외과적 수술을 통한 치료가 불가능한 경우가 있다. 이 발명은 수술적 치료가 불가능한 병변 부위에 금속성분의 코일을 삽입해 줌으로서 치료의 효과를 볼 수 있기 위한 발명이다.Patients with vascular diseases such as aneurysms may not be able to be treated through surgical operation of the lesion due to other causes such as hypertension or heart disease. This invention is an invention for the effect of the treatment by inserting a coil of metal components in the lesion site that is not surgical treatment.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
동맥류(혈관이 풍선처럼 커지는 질환)의 병변부위에 대퇴동맥을 통하여 가는 튜브를 삽입하고 그 튜브의 내부통로를 통하여 금속코일을 병변부위에 밀어넣어 채워준다. 이 코일은 병변부위 혈류를 차단하여 혈액을 응고시키고 병변부위는 더 이상 커지지 않아 혈관의 파열을 방지할 수 있게 된다.Insert a tube that goes through the femoral artery to the lesion of an aneurysm (a disease in which the blood vessel grows like a balloon), and pushes the metal coil into the lesion through the inner passage of the tube. The coils block blood flow to the lesions, causing the blood to clot, and the lesions no longer grow to prevent rupture of blood vessels.

Description
종래의 치료방법은 외과적 수술을 통한 방법으로 질환부위를 직접 절개하거나 클립으로 묶어주는 방법으로 전신마취 수술을 통해서만 가능하였다. 이 경우 환자는 절개수술 자체가 주는 고통과 공포, 오랜 회복시간이 필요한 문제점이 있었다. 또한 고혈압, 심장병등의 기타 질병을 동반하고 있어 수술자체가 불가능한 환자의 경우도 많다.Conventional treatment methods are only possible through general anesthesia surgery in a method of directly cutting or tying the diseased area with a surgical method. In this case, the patient had the pain and fear of the incision itself, and a long recovery time was required. In addition, many patients with high blood pressure, heart disease, etc., the operation itself is impossible.
(1)의 문제점을 해결하기 위하여 수술이 불가능한 환자의 경우 수술을 하지 않고 치료를 하기 위하여 방사선 투시를 통해 병변의 위치를 확인하고 그 부위에 금속성분의 코일을 삽입하여 혈류를 차단하여 치료효과를 거두기 위한 것이다.In order to solve the problem of (1), in order to treat the patient without surgery, the position of the lesion is checked through radiation fluoroscopy, and the coil of metal component is inserted into the site to block the blood flow to treat the effect. It is to harvest.

본 발명은 금속선으로 나선형 1차 코일링(제2도)을 한 후 다시 그것을 열처리를 통해 2차 코일링(제1도)을 한 것이다. 이 1차 코일링의 크기(2)는 금속코일이 병변부위까지 도달할 수 있도록 길잡이 역할을 하는 혈관도자(3)의 내경보다 약간 가는 크기로 제작된다. 이 1차 코일은 원하는 형태의 틀에 나선형으로 감아 열처리하여 2차 코일링을 한다. 이 2차 코일링의 크기(1)는 동맥류(4)의 지름과 비슷한 크기로 제작된다. 여기서 나선형 1차 코일로 구성되는 이유는 금속선이 직선형태의 펴진상태로 혈관도자(3)의 내경을 통해 들어가서 혈관 도자의 끝에서 다시 코일형태(7)로 되돌아와야 하는 형태의 변화에 적응하기 위한 구성이다. 또한 혈액을 응고시키는 역할을 효과적으로 수행하기 위하여 나선형 코일형태는 혈액과 만나는 접촉면적을 증가시키는 장점도 지닌다.According to the present invention, the first coil is spirally wound with a metal wire (FIG. 2), and then the second coil is subjected to heat treatment. The size of the primary coiling (2) is made to be slightly smaller than the inner diameter of the vascular conductor (3) that serves as a guide to the metal coil to reach the lesion site. The primary coil is wound in a spiral around a frame of a desired shape and subjected to secondary coiling. The size of this secondary coiling 1 is made to be similar to the diameter of the aneurysm 4. The reason why it is composed of a spiral primary coil is to adapt to the change of shape in which the metal wire enters through the inner diameter of the blood vessel conductor 3 in a straight line in a straight state and returns from the end of the blood vessel conductor to the coil form 7 again. Configuration. In addition, the spiral coil form has the advantage of increasing the contact area with the blood to effectively coagulate the blood.
혈관도자(3)를 안내철선(6)과 함께 방사선투시하에서 대퇴동맥 천자법으로 병변부위의 입구까지 장착한다(현재 진단방사선괴의 혈관조영술로 일반적으로 시행되고 있는 진단 방법임). 혈관도자의 내경을 통하여 금속 코일을 병변부위에 안내 철선(6)으로 밀어넣는다(나). 충분한 양의 금속 코일을 삽입하고(다) 혈관도자와 안내철선을 제거하면 병변부위에 금속 코일이 남아(라) 혈류의 흐름을 방해함과 동시에 혈액을 응고시켜 동맥류가 더 이상 커지는 것을 방지하는 효과를 얻게 된다. 이상은 금속코일이 동맥류의 치료에 적용되는 치료방법을 기술한 것이다. 금속코일을 이와 같은 방법으로 혈관내 혈류를 차단하고자 하는 목적의 의료용 색전물질로 광범위하게 사용되어질 수 있다.The vascular catheter 3 is attached to the lesion site by the femoral puncture technique with the guide wire 6 (this is a diagnostic method currently generally performed by angiography of diagnostic radiographs). The metal coil is pushed into the lesion site with the guide wire 6 through the inner diameter of the vessel (B). Inserting a sufficient amount of metal coil (c) and removing the blood vessels and guide wires will leave a metal coil at the lesion site that will block the flow of blood and coagulate blood, preventing the aneurysm from growing any longer. You get The above describes the treatment method in which the metal coil is applied to the treatment of an aneurysm. Metal coils can be widely used as a medical embolic material for the purpose of blocking blood flow in the blood vessel in this way.
대표적으로 외상으로 인한 동정맥루(동맥과 정맥에 통로가 형성되어 동맥의 혈류가 모세혈관 및 장기를 통하지 못한체 정맥으로 흘러 버리는 질환), 선천성 동정맥 기형의 치료, 간암등의 악성조양으로 통하는 혈관을 금속 코일로 막아 혈류의 공급을 차단함으로써 종양을 괴사시키는 색전술등에 사용될 수 있다.Typically, arteriovenous fistula due to trauma (paths formed in arteries and veins, which causes blood flow in arteries to flow into capillaries and veins that cannot pass through organs), treatment of congenital arteriovenous malformations, and blood vessels leading to malignant conditions such as liver cancer. It can be used for embolization such as tumor necrosis by blocking the supply of blood flow.
이와 같이 본 고안은 간단한 구조로 신체의 혈관을 막아줌으로서 치료의 성과를 얻을 수 있는 혈관질환의 치료를 위해 외과적인 수술을 하지 않고 방사선 투시하에서 금속 코일을 색전물질로 사용하여 치료함으로써 환자의 고통을 최소화하고 치료 시간을 현저히 단축시켜 빠른 회복으로 시회에 복귀 시킴을 위한 것이다.As such, the present invention is a simple structure that prevents the patient's blood vessels, and the patient's pain by treating the vascular disease that can achieve the result of treatment by using metal coil as embolic material under the fluoroscopy without surgical operation. To minimize the risk and significantly shorten the treatment time to return to the trial with rapid recovery.
본 발명은 금속성분의 의료용 색전물질에 관한 것으로서 혈관질환 부위에 삽입하여 혈관을 막아주어 혈류를 차단시키는 치료효과를 거두기 위한 발명이다.The present invention relates to a medical embolic material of a metal component is inserted into the vascular disease site to block the blood vessels to achieve the therapeutic effect of blocking the blood flow.
