Description

카테터 풀백 연결 조인트 시스템Catheter full back connection joint system
본 발명은 카테터 풀백 연결 조인트 시스템에 관한 것이다.The present invention relates to a catheter pullback connection joint system.
병변을 진단 및 치료하기 위해서 여러 의학 분야에서 의료 영상을 필요로 하고 있다.In order to diagnose and treat a lesion, medical images are required in various medical fields.
의료 영상 중 혈관의 상태를 파악할 수 있는 방법으로 초음파를 이용하여 영상을 진단하는 혈관내 초음파(IVUS)가 있다. 혈관내 초음파(IVUS)는 카테터를 이용하여 관상동맥뿐만 아니라 말초 혈관에서도 이용되는데, 특히 심장에 이용될 경우에는 관상동맥내 영상이라고 한다. 상기와 같은 의료 영상은 혈관 속 상태를 확인할 수 있으므로 진단 및 치료에 유용하게 사용된다.Among the medical images, there is intravascular ultrasound (IVUS), which diagnoses images using ultrasound as a method for determining the state of blood vessels. Intravascular ultrasound (IVUS) is used not only in coronary arteries but also in peripheral blood vessels using a catheter. In particular, when used in the heart, it is referred to as an intravascular image. The medical image as described above is useful for diagnosis and treatment because it is possible to check the condition in the blood vessels.
혈관내 초음파는 초음파 변환자를 혈관에 삽입하여 영상화를 수행하기 때문에 초음파 변환자의 지름은 1mm 이내 이어야 하고, 고해상도 영상을 획득하기 위해서 사용하는 주파수는 20-100 MHz 대역의 고주파이어야 한다. 즉, 기기는 소형이면서도 높은 주파수의 초음파를 송수신할 수 있어야 한다.Since intravascular ultrasound imaging is performed by inserting an ultrasound transducer into a blood vessel, the diameter of the ultrasound transducer should be within 1 mm, and the frequency used to acquire a high-resolution image should be high frequency in the 20-100 MHz band. That is, the device should be capable of transmitting and receiving ultrasonic waves having a small size and high frequency.
혈관 내 영상은 직접 혈관 내로 카테터를 넣어 혈관 내부를 눈으로 볼 수 있으므로 혈관에 대한 이해뿐 아니라 좀 더 정확한 시술을 할 수 있다. 특히 카테터를 혈관 내로 삽입하고 목표 영역을 촬영하여 혈관벽의 동맥경화와 석회화 등의 혈관 내부 상태를 정확하게 진단할 수 있게 해준다.The intravascular image can be directly inserted into the blood vessel to visually view the inside of the vessel, so that not only the understanding of the blood vessel but also a more accurate procedure can be performed. In particular, the catheter is inserted into the blood vessel and the target region is photographed to accurately diagnose the internal condition of the blood vessel, such as arteriosclerosis and calcification of the blood vessel wall.
또 다른 기술로 광학 기술에 기반을 둔 광단층촬영(OCT)이 있다. 상기와 같은 방법은 영상 진단 부위와 영상 검출기 사이에 있는 축을 따라 광신호를 전달하기 위하여 하나 또는 그 이상의 광파이버를 요구한다.Another technique is optical tomography (OCT) based on optical technology. Such a method requires one or more optical fibers to transmit an optical signal along an axis between the image diagnosis site and the image detector.
또 다른 기술로 광음향단층촬영 영상(PhotoAcoustic Tomography)기술은 광음향 효과를 이용하여 비침습적으로 생체조직을 영상화하는 기술이다. 광음향단층촬영 영상 기술은 전자기파를 초음파로 변환하여 측정하기 때문에 광학적 영상 특성과 초음파 영상의 특징을 혼합할 수 있는 장점을 가지고 있다.Another technique is a photoacoustic tomography (PhotoAcoustic Tomography) technique that uses a photoacoustic effect to non-invasively image biological tissue. Since the photoacoustic tomography imaging technology converts electromagnetic waves into ultrasonic waves and measures them, it has the advantage of mixing optical image characteristics and ultrasonic image characteristics.
상기와 같은 영상진단 기술은 소화기내 계열, 관상동맥 등의 심장 혈관 계열, 주변 및 신경 혈관계, 피부, 눈, 생식기 계열, 가슴 조직, 간 조직 등의 많은 분야에서 응용되고 있다. 특히 초음파 영상 또는 광단층촬영 영상을 이용한 심장혈관 계열의 영상 진단은 동맥혈 플라크(arterial plaque)의 구조 및 조성을 판단하는 데에 사용된다.The image diagnosis technology as described above has been applied in many fields such as in the digestive system, cardiovascular systems such as coronary arteries, peripheral and neurovascular systems, skin, eyes, genital systems, chest tissue, and liver tissue. In particular, the diagnosis of the cardiovascular system using ultrasound images or tomography images is used to determine the structure and composition of arterial plaques.
상기와 같은 영상 기술을 혼합하여 혈관 계열의 영상 진단에서 보다 정밀하고 다양한 병변을 진단하기 위해서 풀백 장치가 구비된 카테터 시스템이 사용된다. 이러한 카테터 시스템에 있어서, 카테터는 신체로부터 광 및 초음파 신호를 송수신하고, 이 신호는 카테터를 이송 및 회전시키는 풀백장치를 거쳐 영상장치를 통해 출력된다.A catheter system equipped with a pullback device is used to diagnose more precise and various lesions in a blood vessel-based image diagnosis by mixing the above-described imaging technology. In such a catheter system, the catheter transmits and receives optical and ultrasonic signals from the body, and this signal is output through an imaging device through a pullback device that transports and rotates the catheter.
일반적으로 광신호 또는 초음파 신호를 통해 한가지의 영상을 제공하는 카테터 시스템과는 달리 상기와 같은 카테터 시스템에서는 복합적인 광신호 및 초음파 신호 전달을 위해 카테터와 풀백 장치사이에 광파이버 또는 전기신호선을 사용하여야 하는데 카테터와 풀백 장치 사이의 초소형의 공간에 부속을 배치함에 어려움이 있다. 따라서, 상기 광파이버 및 전기신호선은 카테터의 길이를 따라 튜브내에 배치됨으로써, 혈관 내 삽입되어야 하는 카테터 구조의 크기를 키우게 된다. 또한, 카테터가 회전하는데 제약을 받고 카테터를 무리하게 회전시킬 때에는 광파이버 및 전기신호선의 꼬임 또는 단선 등의 원인이 되어 시스템이 고장 나거나 잘못된 신호 전달로 인해 의료사고가 발생하는 문제가 있다. Unlike a catheter system that generally provides one image through an optical signal or an ultrasonic signal, in the catheter system as described above, an optical fiber or an electric signal line must be used between the catheter and the pullback device for the transmission of the complex optical signal and the ultrasonic signal. It is difficult to place the accessory in a compact space between the catheter and the pullback device. Therefore, the optical fiber and the electric signal line are arranged in the tube along the length of the catheter, thereby increasing the size of the catheter structure to be inserted into the blood vessel. In addition, when the catheter is restricted from rotating and the catheter is rotated forcibly, it is a cause of twisting or disconnection of the optical fiber and the electric signal line, and there is a problem in that a medical accident occurs due to a system malfunction or incorrect signal transmission.
따라서, 카테터와 풀백장치를 연결함에 있어서 구조적으로 간소화하여 위 문제를 해결할 필요가 있다.Therefore, it is necessary to solve the above problem by simplifying structurally in connecting the catheter and the pullback device.

상술한 전기적 신호 전달과정은 본 발명에 따른 카테터 풀백 연결 조인트 시스템에 의해 이루어질 수 있다.The above-described electrical signal transmission process may be performed by the catheter pullback connection joint system according to the present invention.
본 발명에 따른 카테터 풀백 연결 조인트 시스템은 의 제1 전도성 부재(210) 및 제2 전도성 부재(311)는 다양하게 마련되어질 수 있다. 예를 들어, 얇은 전도성 코팅이 각각 커넥터(200) 및 어댑터(300)에 마련될 수 있고, 얇은 전도성 금속판 형태로 마련될 수 있다. 또한, 바람직하게는 제1 전도성 부재(210)는 커넥터(200) 외면에 도금되고, 제2 전도성 부재(311)는 수용부(310) 내면에 도금된 것을 특징으로 할 수 있다. 이를 통해 커넥터(200)와 어댑터(300)를 전기적으로 연결하는데 필요한 별도의 케이블 및 전선이 불필요하게 되어 협소한 구조 내에서 공간확보가 충분해지므로 제조공정이 보다 수월해질 수 있는 효과가 있다.The first conductive member 210 and the second conductive member 311 of the catheter pullback connection joint system according to the present invention may be provided in various ways. For example, a thin conductive coating may be provided on the connector 200 and the adapter 300, respectively, and may be provided in the form of a thin conductive metal plate. In addition, preferably, the first conductive member 210 is plated on the outer surface of the connector 200, and the second conductive member 311 is plated on the inner surface of the receiving portion 310.
