Description

우산형 색전 장치umbrella embolic device

본 발명의 실시예들은 우산형 색전 장치에 관한 것으로, 보다 상세하게는 혈관 내 설치가 용이하고, 즉각적으로 혈류를 차단할 수 있는 우산형 색전 장치에 관한 것이다.Embodiments of the present invention relate to an umbrella-type embolic device, and more particularly, to an umbrella-type embolic device that can be easily installed in a blood vessel and can immediately block blood flow.

일반적으로 인터벤션(intervention) 시술 중 출혈이나, 동정맥루(arteriovenous fistula) 등의 질환이나 각종 혈류 차단을 위하여 혈관의 내부에 색전 기구가 삽입된다.In general, an embolic device is inserted into a blood vessel to block blood flow or diseases such as bleeding or arteriovenous fistula during an intervention procedure.

종래 색전 기구의 일 예로서 코일 형상의 색전 기구를 사용하였는데, 코일 형상의 색전 기구는 혈관 등의 대상체의 내부에서 원하는 부위에 정확하게 삽입하기가 어렵고, 삽입 후에 이동이 발생하며, 코일이 수회 감겨야 충분한 색전 효과를 얻을 수 있고, 대상체의 내부에 삽입하는 과정이 기술적으로 어렵고 사용자의 숙련도가 요구되는 문제점이 있엇다.As an example of the conventional embolic device, a coil-shaped embolic device was used. The coil-shaped embolic device is difficult to accurately insert into a desired site inside an object such as a blood vessel, and movement occurs after insertion, and the coil needs to be wound several times. There is a problem that a sufficient embolism effect can be obtained, and the process of inserting it into an object is technically difficult and requires skill of the user.

또한, 코일 형상의 색전 기구의 단점을 보완하기 위한 AVP(Amplatzer Vascular Plug)는 코일 형상의 색전 기구에 비해 삽입이 비교적 안정적으로 삽입이 가능하나 이를 위하여 굵은 도관이나 유도관이 필요하고, 굴곡이 심한 혈관이나, 상대적으로 얇은 혈관에는 삽입이 불가능하고, 무리하게 삽입하는 경우 혈관이 손상될 수 있는 문제점이 있고 구조적인 한계로 색전이 즉각적이지 못하거나 재개통의 위험성이 있었다.In addition, the AVP (Amplatzer Vascular Plug) to compensate for the shortcomings of the coil-shaped embolic device can be inserted relatively stably compared to the coil-shaped embolic device. It is impossible to insert into a blood vessel or a relatively thin blood vessel, and there is a problem that the blood vessel may be damaged if inserted forcibly.

본 발명의 배경기술은 대한민국 공개특허공보 제10-2015-0127135호(2015.11.16 공개, 발명의 명칭: 색전술 시스템)에 개시되어 있다.The background technology of the present invention is disclosed in Korean Patent Publication No. 10-2015-0127135 (published on November 16, 2015, title of the invention: Embolization system).

본 발명은 상기와 같은 문제점을 개선하기 위해 안출된 것으로, 우산 형상으로 형성되며, 펼쳐지거나 접힘 가능한 제2프레임부와 제1프레임부, 제2프레임부를 커버하는 차단막부로 인하여 설치가 용이하고, 즉각적으로 혈류를 차단할 수 있는 우산형 색전 장치를 제공하고자 한다.The present invention has been devised to improve the above problems, is formed in an umbrella shape, and is easy to install due to the second frame part, the first frame part, and the blocking film part covering the second frame part that can be unfolded or folded, An object of the present invention is to provide an umbrella-type embolic device capable of immediately blocking blood flow.

그러나 이러한 과제는 예시적인 것으로, 이에 의해 본 발명의 범위가 한정되는 것은 아니다.However, these problems are exemplary, and the scope of the present invention is not limited thereto.

A hole portion is formed in the contact frame 230 , and various modifications such as the fixing frame 210 being inserted into the object 10 through the hole formed in the contact frame 230 are possible.

이 때 고정프레임(210)은 접촉프레임(230)에 형성되는 홀부에 결합되어 위치 고정되고, 접촉프레임(230)에 형성되는 홀부를 통과한 고정프레임(210)의 미리 설정되는 길이만큼만 대상체(10)에 삽입될 수 있다.At this time, the fixed frame 210 is coupled to the hole formed in the contact frame 230 and fixed in position, and only the fixed frame 210 passes through the hole formed in the contact frame 230 by a preset length of the object 10 . ) can be inserted.

도 4를 참조하면, 홀부(212)는 고정프레임(210)에 형성되는 것으로 고정프레임(210) 상에서 길이 방향을 따라 미리 설정된 길이만큼 형성될 수 있다. Referring to FIG. 4 , the hole 212 is formed in the fixed frame 210 and may be formed by a preset length along the longitudinal direction on the fixed frame 210 .

상기 홀부(212)에 접촉프레임(230)이 통과하여 대상체(10)의 내주면에 접촉됨으로 인하여 고정프레임(210), 구체적으로 절곡부(211)가 미리 설정되는 깊이를 초과하여 혈관 등의 대상체(10)에 박힘으로써 혈관이 손상되는 것을 방지할 수 있다.Because the contact frame 230 passes through the hole 212 and comes into contact with the inner circumferential surface of the object 10, the fixed frame 210, specifically, the bent portion 211 exceeds a preset depth, so that the object (such as a blood vessel) 10) can prevent damage to blood vessels by being embedded in the

다시 말하여 고정프레임(210)이 대상체(10)에 박힌 상태로 혈류(BF)가 빠르거나 혈압이 높게 형성되는 경우에 제2프레임부(300), 차단막부(400)에 압력이 지속적으로 전달되어 필요 이상으로 대상체(10)에 삽입되는 경우가 발생되는데, 이로 인하여 혈관이 손상되는 것을 방지할 수 있다.In other words, when the fixed frame 210 is embedded in the object 10 and the blood flow (BF) is fast or the blood pressure is high, the pressure is continuously transmitted to the second frame unit 300 and the blocking unit 400 . Therefore, there is a case where it is inserted into the object 10 more than necessary, thereby preventing damage to the blood vessel.

이에 더하여 접촉프레임(230)은 고정프레임(210)에 형성되는 홀부(212)를 통과하여 혈관 등의 대상체(10)와 면 접촉할 수 있어 대상체(10)의 내주면을 안정적으로 지지하며 배치될 수 있다. In addition, the contact frame 230 passes through the hole 212 formed in the fixed frame 210 to be in surface contact with the object 10 such as blood vessels, so that the inner peripheral surface of the object 10 can be stably supported and disposed. have.

도 1, 도 4를 참조하면, 본 발명의 일 실시예에 따른 접촉프레임(230)은 본체부(100)에서 외측 방향으로 오목하게 형성되는 고정프레임(210)과 달리, 본체부(100)에서 외측 방향으로 볼록하게 형성될 수 있다. Referring to FIGS. 1 and 4 , the contact frame 230 according to an embodiment of the present invention is different from the fixed frame 210 which is concave outwardly from the main body 100 , in the main body 100 . It may be formed to be convex in an outward direction.

접촉프레임(230)이 본체부(100)에서 외측 방향으로 볼록하게 형성됨으로 인하여 접촉프레임(230)의 단부가 혈관 등의 대상체(10)를 뚫는 방향이 아닌 대상체(10)의 내주면에 완만하게 접촉될 수 있는 효과가 있다.Because the contact frame 230 is convexly formed outwardly from the main body 100 , the end of the contact frame 230 gently contacts the inner peripheral surface of the object 10 , not in the direction in which the object 10 such as blood vessels pierce. can have an effect.

이에 더하여 접촉프레임(230)이 고정프레임(210)에 형성되는 홀부(212)에 걸쳐짐으로 인하여 대상체(10)의 내주면에 미리 설정되는 길이만큼 접촉할 수 있고, 고정프레임(210)이 미리 설정되는 깊이 이상으로 대상체(10)에 삽입되는 것을 방지할 수 있다.In addition, since the contact frame 230 spans the hole 212 formed in the fixed frame 210, it can contact the inner circumferential surface of the object 10 by a preset length, and the fixed frame 210 is set in advance. It can be prevented from being inserted into the object 10 beyond the desired depth.
