Description

스텐트 삽입장치{Inserting device of stent}Insting device of stent

본 발명은 혈관의 동맥류와 같은 병변부위에 삽입, 팽창되어서 혈관을 보호하는 스텐트의 삽입장치에 관한 것으로, 특히 분지된 혈관에 스텐트를 선택적으로 팽창시키면서 병변부위에 정확하게 안착시켜 줄 수 있는 스텐트 삽입장치에 관한 것이다.The present invention relates to a device for inserting and expanding a stent to protect a blood vessel by inserting and expanding a lesion such as an aneurysm of a blood vessel, and in particular, a stent insertion apparatus capable of accurately seating a lesion while selectively expanding the stent to a branched blood vessel. It is about.

종래의 스텐트 삽입장치는 한개의 시즈(Sheath)의 일측내부에 부피가 축소된 상태로 장입(loading)된 스텐트를 삽입편과 한쪽끝이 고정된 가이드와이어를 안내해주는 가이드패싱튜브를 이용하여 혈관내 병변부위로 삽입한 후 상기 스텐트의 후방에 끼워져 있으며 한쪽이 막혀진 경질의 푸셔(Pusher)로 스텐트를 팽창시켜 줄 수 있도록 된 것이다.Conventional stent insertion device uses a guide passing tube to guide the insertion wire and the guide wire fixed to one end of the stent loaded in the state of reduced volume in one side of one sheath (Sheath) in the blood vessel After insertion into the lesion, the stent is inserted into the back of the stent, and one side of the rigid pusher is used to inflate the stent.

따라서, 종래의 스텐트 삽입장치는 푸셔로 스텐트를 밀어줄 때 시즈의 내주면과 푸셔의 외주면간의 마찰로 인하여 시즈를 후진시켜주는데 큰 힘이 요구되었었을 뿐만아니라 혈액흐름에 따른 저항으로 말미암아서 정확한 병변위치에 시술하기 가 매우 어려웠었다.Therefore, the conventional stent insertion device requires a large force to reverse the siege due to friction between the inner circumferential surface of the sheath and the outer circumferential surface of the pusher when the stent is pushed by the pusher, and the accurate lesion position due to the resistance of the blood flow. It was very difficult to operate on.

특히, 스텐트가 시즈를 벗어나면서 한번에 팽창되는 것이어서 즉, 스텐트의 선단부가 병변위치에 자리를 잡기도 전에 스텐트 전체가 팽창하게 되었었고 또 후방으로도 끌어당겨지게 되어서 분지된 혈관에 스텐트를 정확하게 시술하기가 어려웠었다.In particular, the stent is inflated at one time as it leaves the siege, that is, the entire stent is expanded and pulled backwards before the stent's tip is positioned in the lesion position. It was difficult.

본 발명의 목적은 시즈에 장입된 스텐트의 선단부를 선택적으로 먼저 분지된 혈관에 팽창시켜 줄 수 있도록 함으로써 스텐트를 병변위치에 정확하게 시술 할 수 있으며 시즈를 보다 작은힘으로도 용이하게 후진시켜 줄 수 있어 시술이 보다 편리한 스텐트 삽입장치를 제공하는데 있다.It is an object of the present invention to selectively expand the tip of the stent loaded into the sheath to the first branched blood vessel, so that the stent can be precisely operated at the lesion position and the sheath can be easily retracted with a smaller force. The procedure is to provide a more convenient stent insertion device.

본 발명은 스텐트 삽입장치에 관한 것으로서, 스텐트가 직경을 최소화 시켜준 상태로 장입되는 시즈를 포함하며, 상기 스텐트를 관통하며 삽입편과 한쪽끝이 고정된 가이드와이어를 안내하는 가이드팽싱튜브의 선단부쪽 외주면에는 풀리가 풀리고정와이어로 회전가능하게 고정되어 있으며, 상기 시즈의 선단부쪽에 한쪽 끝부분이 고정된 당김줄이 상기 풀리를 경유하여 상기 가이드패싱튜브의 선단부쪽에 형성시킨 구멍을 통해서 가이드패싱튜브속을 관통하여 상기 시즈의 타측에 있는 손잡 이 밖으로 연장되어 있는 것을 특징으로 한다.The present invention relates to a stent inserting apparatus, comprising a sieve loaded in a state in which the stent is minimized in diameter and penetrating the stent and leading to a guide wire having a guide wire fixed with an insertion piece and one end thereof. The pulley is pulled out on the outer circumference and is rotatably fixed with a fixed wire, and a pull string having one end fixed to the front end of the sheath through a hole formed in the front end of the guide passing tube via the pulley. It is characterized in that penetrating through the handle is located on the other side of the sheath.

또한, 본 발명은 스텐트 삽입장치에 관한 것으로서, 스텐트가 직경을 최소화시켜준 상태로 장입되는 시즈가 제1시즈와, 상기 스텐트의 선단부가 장입되는 제2시즈로 이루어져 있으며, 상기 제2시즈의 후단부는 상기 제1시즈의 선단부와 겹쳐지도록 되어 있고, 상기 스텐트를 관통하며 삽입편과 한쪽끝이 고정된 가이드와이어를 안내하는 가이드패싱튜브의 선단부쪽에는 풀리가 풀리고정와이어로 회전가능하게 고정되어 있으며, 상기 제2시즈의 선단부쪽에 한쪽끝부분이 고정된 당김줄이 상기 풀리를 경유하여 가이드패싱튜브의 선단부쪽에 형성시킨 구멍을 통해서 가이드패싱튜브 속을 관통하여 제1시즈의 타측에 있는 손잡이 밖으로 연장되어 있는 것을 특징으로 한다.In addition, the present invention relates to a stent inserting apparatus, wherein a sieve loaded with the stent minimized in diameter is composed of a first sieve and a second sieve loaded with a tip of the stent, and a rear end of the second sieve. The part is overlapped with the front end of the first sheath, and the pulley is unwinded and rotatably fixed to the front end of the guide passing tube which guides the guide wire through which the insertion piece and one end are fixed and penetrate the stent. A pull string having one end fixed to the distal end of the second sheath extends out of the handle on the other side of the first sheath through a hole formed in the distal end of the guide passing tube via the pulley. It is characterized by that.

본 발명은 스텐트가 장입되는 시즈가 스텐트의 선단부가 장입되는 제2시즈와, 스텐트의 나머지부분들이 장입되는 제1시즈로 이루어져 있으며, 상기 제2시즈는 가이드패싱튜브를 관통하는 당김줄을 잡아당겨서 제2시즈 속에 있는 스텐트의 선단부를 분지된 혈관의 넓은 부위에 먼저 안착시켜준 상태에서 제1시즈속에 있는 스텐트의 나머지 부분들을 혈관속에 안착시켜줄 수 있도록 된 것이어서 스텐트를 분지된 혈관의 병변부위에 보다 쉽고 정확하게 시술할 수 있는 장점이 있다.According to the present invention, a sieve is loaded with a second sieve into which the front end of the stent is loaded, and a first sieve into which the rest of the stent is loaded, and the second siege pulls the pulling string passing through the guide passing tube. The first part of the stent in the second siege was first seated in a large area of the branched blood vessel, and the rest of the stent in the first siege was allowed to settle in the blood vessel so that the stent was placed on the lesion of the branched blood vessel. There is an advantage that can be easily and accurately performed.

또 본 발명은 시즈를 보다 작은힘으로 쉽게 제거하여 시술이 매우 용이한 장점도 있다.In addition, the present invention has the advantage that the procedure is very easy to remove the sheath with a smaller force.

본 발명을 첨부된 예시도면을 참조하여 상세히 설명하면 다음과 같다. 본 발명은 도 1에 예시한 바와 같이 스텐트(10)가 직경을 최소화 시켜준 상태로 장입(loading)되는 시즈(sheath)(12)를 포함하며, 상기 스텐트(10)를 관통하며 삽입편(24)과 한쪽 끝이 고정된 가이드와이어(26)를 안내하는 가이드패싱튜브(28)의 선단부쪽 외주면에는 풀리(30)가 풀리고정와이어(32)로 회전가능하게 고정되어 있으며, 상기 시즈(12)의 선단부쪽에 한쪽 끝부분(34)이 고정된 당김줄(26)이 상기 풀리(30)를 경유하여 상기 가이드패싱튜브(28)의 선단부쪽에 형성시킨 구멍(38)을 통해서 가이드패싱튜브(28)속을 관통하여 상기 시즈(12)의 타측에 있는 표현이 생략된 손잡이 밖으로 상기 가이드와이어(26)와 함께 연장되어 있다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
