Abstract
The present invention relates to a structure of a catheter for a surgical stent having a short guidewire. In the structure of a catheter for a surgical stent, when a surgical stent operation is performed, a guidewire of a length that is enough to guide the surgical stent may be used to reduce the surgical operating time and improve surgical operating convenience. Also, the catheter may guide the entrance and exit of the guidewire and prevent the guidewire from being twisted. Furthermore, an external tube hole and an internal tube hole, which communicate with each other, may be defined in a point about 1/3 from the front end of the total length of the external and internal tubes. Thus, the external and internal tubes may be moved along the guidewire. When the internal tube is moved forward to discharge the stent, thereby expanding a lesion portion, the guidewire is successively inserted into the external and internal tube holes and discharged into a front side of the internal tube to guide the stent to the lesion portion. Here, the guidewire inserted from the external and internal tube holes up to a discharge hole may be adjusted. Also, since the guidewire is inserted through the internal and external tube holes, the length for guiding the guidewire may be relatively shorter when compared to the guidewire being inserted through a grasped body. Thus, an additional length adjustment effect in addition to the guidewire having the relatively short length may be obtained.
Description
본 발명은 스텐트 시술용 카테터의 구조에 관한 것으로, 특히 스텐트를 시술할 때 안내할 수 있는 길이 만큼으로 가이드와이어를 사용할 수 있어 스텐트의 시술시 시간단축 및 시술자의 시술 편의성이 증대되도록 하며, 가이드와이어의 출입 안내와 꼬임이 방지되도록 하는 가이드와이어를 짧게 사용하는 스텐트 시술용 카테터의 구조에 관한 것이다.The present invention relates to the structure of the stent catheter, in particular, the guide wire can be used as long as the guide can be guided when performing the stent to reduce the time and the convenience of the operator during the procedure of the stent, the guide wire It relates to the structure of the stent catheter for short use of the guide wire to prevent the entry and twist of the.
일반적으로, 식도 등의 신체 협착진행 또는 협착부위에 외과적인 수술을 행하지 않고 치료하는 다양한 방법들이 개시되고 있는데, 그중 하나가 초탄성 형상기억합금의 스텐트를 이용한 시술방법이다.In general, various methods for treating a stenosis progression or stenosis without performing a surgical operation are disclosed, one of which is a method using a stent of a superelastic shape memory alloy.
이때, 스텐트를 이용한 시술방법은 초탄성 형상기억합금 소재를 엮어 일정 길이를 갖는 중공식 원통형 몸체로 형성된 스텐트의 부피를 최소화한 상태로 신체의 협착진행 또는 협착부위인 병변부위로 삽입하여 그 부피(기관의 직경)가 원상태로 복원되면서 협착진행 또는 협착부위를 바깥으로 밀어 확장시키도록 시술하는 것이다.At this time, the treatment method using the stent is interwoven with the superelastic shape memory alloy material and inserted into the lesion site, which is the narrowing process or the narrowing area of the body, with the volume of the stent formed by the hollow cylindrical body having a predetermined length minimized. Diameter) is restored to its original state, and the procedure is performed to expand the narrowing process or push the stenosis outward.
이러한, 스텐트를 이용한 시술방법은 스텐트를 신체 협착진행 또는 협착부위로 삽입하도록 시술하기 위해서 별도의 삽입장치가 요구된다.Such a method using the stent requires a separate insertion device to perform the procedure to insert the stent into the body stenosis or stenosis.
이때, 스텐트를 삽입하기 위한 스텐트 삽입장치는 파지몸체에 연결된 외부튜브 내부로 외측에서 이동튜브를 삽입하여 후단에서 전후 이동조절 가능케 구성하되, 상기 외부튜브의 선단 내부에 부피를 축소하여 삽입 장착되는 스텐트를 이동튜브 선단이 밀어서 이동시켜 설치하도록 구성된다.At this time, the stent insertion device for inserting the stent is configured to enable the front and rear movement control at the rear end by inserting the moving tube from the outside into the outer tube connected to the gripping body, the stent is inserted by reducing the volume inside the outer end of the tube The tip of the moving tube is configured to push and move.
이와 같은, 스텐트 삽입장치는 외부튜브의 선단 내부에 스텐트의 부피를 축소하여 삽입 장착한 상태로 혈관 등의 신체 협착진행 또는 협착부위로 삽입하게 된다.As described above, the stent insertion device is inserted into the stenosis proceeding or stenosis site of the blood vessel, such as blood vessels in a state in which the volume of the stent is reduced and inserted into the tip of the outer tube.
이때, 상기 스텐트가 신체의 협착진행 또는 협착부위로 시술할 경우에는 별도로 삽입되는 내시경에 의해 확인하며 시술하게 된다.At this time, when the stent proceeds to the stenosis progression or stenosis of the body, the procedure is confirmed by an endoscope inserted separately.
이와 같이, 상기 스텐트를 설치 위치로 위치한 후에는 이동튜브를 밀어 외부튜브의 선단 내부에서 스텐트를 밀어 내게 되는데, 상기 스텐트의 선단부터 외부튜브에서 밀려나오며 원래의 형태로 팽창 복원되면서 협착진행 또는 협착부위를 바깥으로 밀어내도록 설치되는 것이다.As such, after the stent is placed in the installation position, the moving tube is pushed to push the stent from the inside of the tip of the outer tube, and is pushed out of the outer tube from the tip of the stent and expanded and restored to its original form. It is installed to push outward.
그러나, 상기와 같은 종래의 스텐트 삽입장치는 스텐트를 병변부위로 위치시키기 위해 시술할 때 가이드와이어에 의해 안내되는데 이때, 가이드와이어는 스텐트와 이동튜브의 내부를 관통하면서 파지몸체를 통해 끝단이 배출되며 스텐트를 시술한 후 재 시술을 위해 가이드와이어를 신체에 삽입한 상태로 신체 외부로 배출시켜 유지할 경우 스텐트 삽입장치의 길이보다 약 2배 정도의 긴 길이를 유지해야함으로 신체 외부로 배출된 여유분을 권취시켜 환자의 신체에 부착시켜 보존하게 되어 환자의 자유로운 활동을 저해하는 문제점이 있었다.However, the conventional stent insertion apparatus as described above is guided by guide wires when the stent is placed to the lesion site, and the guide wires are discharged through the grip body while penetrating the inside of the stent and the moving tube. If the guide wire is inserted into the body to be discharged to the outside after the stent is operated, the length of the stent insertion device must be about 2 times longer than the length of the stent insertion device. It is attached to the body of the patient to be preserved to prevent the free activity of the patient.
이로 인하여, 가이드와이어의 가이드 기능을 하면서 배출 길이를 최소화하여 스텐트의 시술 후 스텐트의 재거 시술이나 재 시술을 위해 인체에 남겨두는 길이를 짧게 하여 환자의 거동에 불편함이 없도록 하고, 스텐트의 시술시 가이드와이어의 길이를 짧게 하여 시술 시간 단축과 시술자의 편리성이 증대되도록 하고, 가이드와이어의 출입 및 전후 이동을 위한 안내기능과 꼬임이 방지될 수 있는 스텐트 시술용 카테터가 절실히 요구되는 실정이다.Due to this, the guide length of the guide wire is minimized while the discharge length is minimized to shorten the length left on the human body for the re-treatment or re-treatment of the stent so that there is no discomfort in the behavior of the patient. Shortening the length of the guide wire to shorten the treatment time and increase the convenience of the operator, the situation for the stent operation catheter that can prevent the twist and guide function for entering and moving the guide wire and twisting is urgently required.
이에 본 발명은 상기와 같은 종래 기술의 문제점을 감안하여 안출한 것으로 내,외부튜브홀을 통해 가이드와이어를 삽입함으로써 파지몸체를 통해 삽입할 때 보다 안내를 위한 길이가 짧아지도록 하는 가이드와이어를 짧게 사용하는 스텐트 시술용 카테터의 구조를 제공하는데 목적이 있다.Accordingly, the present invention has been made in view of the problems of the prior art as described above. By inserting the guide wire through the inner and outer tube holes, the guide wire is used shorter than the guide wire to insert the guide wire through the gripping body. The purpose is to provide a structure of a stent catheter for the treatment.
그리고, 본 발명의 다른 목적은 외부튜브의 전체 길이 중 중앙부분의 직경을 가늘게 형성하여 내시경 안으로 카테터에서 배출되는 가이드와이어가 내시경 안에서 자유롭게 움직이도록 하는 목적이 있다.In addition, another object of the present invention is to form a narrow diameter of the center portion of the entire length of the outer tube so that the guide wire discharged from the catheter into the endoscope to move freely in the endoscope.
