Description

협착병변부위 길이측정장치 및 길이측정방법Length measurement device of stenosis lesion and measuring method
본 발명은 협착병변부위 길이를 측정하는 협착병변부위 길이측정장치 및 길이측정방법에 관한 것이다.The present invention relates to a stenosis lesion length measuring device and a length measuring method for measuring the length of the stenosis lesion.
신체에서 종양이 발생하거나 궤양 등 염증이 생기는 경우, 식도, 위, 십이지장, 소장, 대장 등의 특정신체부위를 막거나 좁게 만들 수 있다. 이러한 협착부위를 넓히는 풍선확장술이나 스텐트 삽입 등의 시술을 수행하기 위해서는 막힌 길이가 어느 정도 되는지 파악할 필요가 있다.When the body develops tumors or inflammations such as ulcers, it can block or narrow certain body parts, such as the esophagus, stomach, duodenum, small intestine, and large intestine. In order to perform a procedure such as balloon dilation or stent insertion to widen the narrowing area, it is necessary to understand how long the blockage is.
기존에는 조영제를 투여한 후 방사선 촬영을 하여 협착병변부위를 측정하였지만, 방사선촬영영상은 2D이미지이므로 3차원 상의 정확한 길이를 파악하는데 어려움이 있다.Conventionally, stenosis was measured by radiographic imaging after administration of contrast medium, but since the radiographic image is a 2D image, it is difficult to determine the exact length in three dimensions.
또한, 관강 내의 협착병변이 존재하는 부위를 단순히 통과한 길이를 측정하는 것은 협착병변부위가 굴곡질 수 있어서 정확하지 않을 수 있다.In addition, simply measuring the length of passage through the site of the stenosis lesion in the lumen may not be accurate because the stenosis lesion may be curved.
협착병변부위의 길이가 정확히 측정되지 않는 경우, 협착 부위를 넓히기 위해 필요한 스텐트의 길이를 정확히 알 수 없게 되어, 스텐트가 너무 길어지거나 짧아지게 될 수 있다. 스텐트가 너무 긴 경우, 쓸데없는 스텐트의 낭비 및 정상 내강에 합병증을 일으킬 수 있다. 스텐트가 너무 짧은 경우, 협착의 부위를 전부 넓히지 못해 추가 스텐트 시술이 필요할 수 있다. 그러므로, 협착 부위의 정확한 길이를 측정하는 것은 매우 중요하다.If the length of the stenosis lesion is not accurately measured, the length of the stent needed to widen the stenosis is not known exactly, and the stent may become too long or too short. If the stent is too long, it can lead to waste of stent and complications in the normal lumen. If the stent is too short, it may not be possible to widen the area of stenosis and further stent surgery may be necessary. Therefore, it is very important to measure the exact length of the constriction site.

또한, 협착병변부위 길이측정장치를 협착병변부위에 삽입한 후 내시경 또는 방사선촬상장치를 통해 협착병변부위의 길이를 측정함에 따라, 의료진이 수술 계획을 정확히 세울 수 있도록 하는, 협착병변부위 길이측정방법을 제공하고자 한다.In addition, the stenosis lesion length measurement device is inserted into the stenosis lesion site, the endoscopy or radiographic apparatus to measure the length of the stenosis lesion, so that the medical staff can accurately plan the operation, stenosis lesion length measurement method To provide.

본 발명에 따르면, 협착병변부위의 정확한 길이를 측정할 수 있다. 즉, 3차원 공간상 굴곡진 관강(즉, 십이지장, 식도, 대장 등)에서의 협착병변부위의 길이를 산출할 수 있다. 또한, 협착병변부위의 굴곡에 영향을 받지 않고 정확한 길이를 파악할 수 있다.According to the present invention, the exact length of the stenosis lesion can be measured. That is, the length of the stenosis lesion in the curved lumen (ie, duodenum, esophagus, large intestine, etc.) in three-dimensional space can be calculated. In addition, it is possible to determine the exact length without being affected by the curvature of the stenosis lesion.
또한, 내시경으로 눈금을 확인함에 따라, 내시경으로 협착병변부위를 확인하면서 바로 병변부위의 길이를 쉽게 파악할 수 있다.In addition, as the scale is confirmed by the endoscope, it is possible to easily determine the length of the lesion site while confirming the stenosis lesion site by the endoscope.

Through this, by using a stent of a length that does not match the condition of the patient it is possible to reduce the possibility of complications that can occur in the normal lumen of the patient. In addition, since the exact length of the constriction site is not known, the use of the long stent after the short stent is reduced, thereby reducing the cost of medical care.

이하, 도면을 참고하여, 본 발명의 일실시예들에 따른 협착병변부위 길이측정장치 및 길이측정방법을 설명한다.Hereinafter, an apparatus for measuring a length of a stenosis lesion length and a length measuring method according to embodiments of the present invention will be described.
도 1을 참조하면, 본 발명의 일실시예에 따른 협착병변부위 길이측정장치(10)는, 가이드관(100); 공기주입관(200); 확장부(300); 및 공기주입기(400);를 포함한다. 이하, 각 구성에 대한 구체적인 설명을 기재한다.Referring to Figure 1, the stenosis lesion site length measuring apparatus 10 according to an embodiment of the present invention, the guide tube 100; Air injection pipe 200; Extension 300; And an air injector 400. Hereinafter, the detailed description about each structure is described.
가이드관(100)은, 협착병변부위(2)를 통과하는 관에 해당한다. 가이드관(100)은 관강(1)의 굴곡을 따라서 휘어질 수 있는 물질로 형성될 수 있으며, 내부에 후술되는 공기주입관(200) 등의 하나 이상의 관을 포함할 수 있다. Guide tube 100 corresponds to a tube passing through the stenosis lesion (2). Guide tube 100 may be formed of a material that can be bent along the bending of the lumen (1), may include one or more tubes, such as the air injection pipe 200 to be described later.
가이드관(100)은 협착병변부위로 다양한 방식으로 삽입될 수 있다. 일실시예로, 가이드관(100)은 내시경관(20) 내로 삽입되고, 내시경관(20)을 통해 관강(1)에 형성된 협착병변부위 주변까지 삽입될 수 있다. 예를 들어, 가이드관(100) 삽입 시에 내시경의 겸자공 즉, 작업 채널을 구비한 내시경관(20)을 이용할 수 있다. Guide tube 100 may be inserted into the stenosis lesion in various ways. In one embodiment, the guide tube 100 may be inserted into the endoscope tube 20, and may be inserted into the stenosis lesion area formed in the lumen 1 through the endoscope tube 20. For example, when the guide tube 100 is inserted, the endoscope tube 20 having the forceps of the endoscope, that is, the working channel may be used.
또한, 다른 일실시예로, 가이드관(100)은 구강 또는 항문을 통해 신체 내부로 직접 삽입될 수도 있다. 예를 들어, 후술하는 바와 같이 가이드관이 스텐트삽입관을 구비하는 경우, 사용되는 스텐트의 두께가 두꺼우면 내시경의 겸자공 내로 삽입하지 못할 수 있다. 이러한 경우, 가이드관(100)은 내시경의 겸자공을 통하지 않고 직접 신체 내부로 삽입될 수 있고, 후술되는 바와 같이 조영물질 또는 형광물질로 된 가이드관 상의 식별표지에 의해 방사선 촬영을 수행하여 협착병변길이를 측정할 수 있다.In another embodiment, the guide tube 100 may be directly inserted into the body through the oral cavity or anus. For example, when the guide tube is provided with a stent insertion tube as described below, if the thickness of the stent is thick, it may not be inserted into the forceps of the endoscope. In this case, the guide tube 100 may be inserted directly into the body without passing through the forceps of the endoscope, and as described below, the stenosis is performed by performing radiographic imaging with an identification mark on a guide tube made of a contrast material or a fluorescent material. The length can be measured.
가이드관(100)은 식별표지를 구비할 수 있다. 상기 식별표지는, 협착병변부위의 길이를 확인 가능한 눈금자(110)로 형성되어 가이드관(100)의 표면에 표시될 수 있다. 즉, 가이드관(100)은 협착병변부위(2)의 길이를 내시경 또는 방사선촬영장치를 이용하여 측정하기 위한 눈금자를 확인할 수 있다. 예를 들어, 의료진이 내시경관의 겸자공을 통해 가이드관을 삽입하며 내시경의 통해 협착병변부위를 확인하는 경우, 의료진은 내시경을 통해 협착병변부위에 인접한 눈금을 확인하여 협착병변부위의 길이를 측정할 수 있다. Guide tube 100 may be provided with an identification mark. The identification mark may be formed on the surface of the guide tube 100 is formed of a ruler 110 that can determine the length of the stenosis lesion. That is, the guide tube 100 can check the ruler for measuring the length of the stenosis lesion (2) using an endoscope or a radiographic apparatus. For example, when a medical staff inserts a guide tube through the forceps of an endoscope and confirms the stenosis lesion area through the endoscope, the medical staff measures the length of the stenosis lesion by checking the scale adjacent to the stenosis lesion area through the endoscope. can do.
상기 눈금자(110)는, 상기 확장부가 상기 협착병변에 접촉되는 지점인 상기 가이드관 상의 지점부터 시작된다. 즉, 의료진에 의해 협착병변길이를 측정하는 경우, 후술되는 공기주입기(400)에 의해 확장부(300)가 팽창되고 길이측정장치(10)를 외부에서 당기게 되면 확장부(300)의 안쪽부분이 협착병변의 일측에 접촉하여 더 이상 이동하지 않게 된다. 따라서, 협착병변부위의 시작지점은 확장부의 안쪽면과 일치할 수 있어서, 확장부가 상기 협착병변에 접촉되는 지점인 상기 가이드관 상의 지점이 눈금자의 시작눈금으로 될 수 있다.The ruler 110 starts from a point on the guide tube that is the point where the extension contacts the stenosis lesion. That is, when measuring the length of the stenosis lesion by the medical staff, when the expansion unit 300 is expanded by the air injector 400 to be described later and the length measuring device 10 is pulled from the outside the inner portion of the expansion unit 300 It will no longer move in contact with one side of the stenosis lesion. Thus, the starting point of the stenosis lesion site may coincide with the inner surface of the dilator so that the point on the guide tube, which is the point where the dilator contacts the stenosis lesion, may be the starting scale of the ruler.
또한, 눈금자(110)는 하나 이상의 눈금에 상기 협착병변의 길이를 확인 가능한 식별표지가 함께 표시될 수 있다. 협착병변부위(2) 내에 배치된 눈금은 내시경을 통해 확인할 수 없으므로, 눈금자(110)의 시작지점으로부터의 길이를 판단하기 위해서는 각 눈금 자체로 길이를 확인할 수 있어야 한다. 따라서, 눈금자의 눈금이 시작지점으로부터의 길이를 나타내는 식별표지를 함께 구비할 수 있다. In addition, the ruler 110 may be displayed with an identification mark that can determine the length of the stenosis lesion on one or more scales. Since the scale disposed in the stenosis lesion site (2) can not be confirmed through the endoscope, in order to determine the length from the start point of the ruler 110, it should be able to check the length by each scale itself. Therefore, the scale of the ruler can be provided with the identification mark which shows the length from a starting point.
예를 들어, 상기 식별표지는 눈금의 주변에 표시된 수치값일 수 있다. 또한, 식별표지는 길이별 눈금 색상일 수 있다. 즉, 의료진은 내시경을 통해 협착병변부위의 말단에 위치한 눈금의 색상을 확인하여 협착병변부위의 길이를 파악할 수 있다. For example, the identification mark may be a numerical value displayed around the scale. In addition, the identification mark may be a grid color for each length. That is, the medical staff can determine the length of the stenosis lesion by checking the color of the graduation located at the distal end of the stenosis lesion through the endoscope.
또한, 눈금자(110)는 기본단위 눈금과 세부단위 눈금을 구비할 수 있다. 세부눈금단위는 기본눈금단위를 세밀하게 분할한 길이단위를 의미한다. 예를 들어, 가이드관(100)에 표시된 기본단위 눈금은 식별표지를 구비하고, 세부단위 눈금은 눈금표시만을 가질 수 있다. 이 때, 의료진은, 내시경으로 가이드관(100)의 표면에 표시된 눈금을 확인하는 경우, 협착병변부위의 말단에 가까운 기본단위의 길이를 식별표지를 확인하고 기본단위로부터 협착병변부위의 말단까지의 세부단위 차이를 파악하여, 협착병변부위의 정확한 길이를 측정할 수 있다. In addition, the ruler 110 may include a basic unit scale and a detailed unit scale. Detailed division unit means the length unit which the basic division unit is divided in detail. For example, the basic unit scale displayed on the guide tube 100 may include an identification mark, and the detailed unit scale may have only a scale mark. At this time, when the medical staff confirms the scale displayed on the surface of the guide tube 100 by an endoscope, the identification mark confirms the length of the base unit close to the end of the stenosis lesion site and the base unit to the end of the stenosis lesion site. By identifying subunit differences, the exact length of the stenosis lesion can be measured.
또한, 상기 눈금자(110)의 하나 이상의 눈금은 조영물질로 형성될 수 있다. 이를 통해, 의료진은 협착병변부위 길이측정장치를 삽입한 후에 방사선영상촬영장치로 환자를 촬영함에 따라 병변길이를 산출할 수 있다. 의료진은 협착병변부위의 일측 말단에서부터 반대측 말단까지의 방사선촬영영상에서 확인되는 눈금개수를 확인하여, 협착병변부위의 길이를 측정할 수 있다.In addition, one or more scales of the ruler 110 may be formed of a contrast material. Through this, the medical staff may calculate the lesion length as the patient is photographed by the radiographic imaging apparatus after inserting the stenosis lesion length measuring device. The medical staff can measure the length of the stenosis lesion by checking the number of graduations found on the radiographic images from one end to the opposite end of the stenosis lesion.
공기주입관(200)은, 상기 가이드관 내에 구비되며, 확장부(300)로 공기를 전달하는 통로에 해당한다. 즉, 공기주입관(200)의 한쪽 끝은 공기주입기(400)로 연결되고, 공기주입관(200) 다른쪽 끝은 확장부(300)로 연결될 수 있다. The air injection pipe 200 is provided in the guide pipe, and corresponds to a passage for delivering air to the expansion unit 300. That is, one end of the air injection pipe 200 may be connected to the air injector 400, and the other end of the air injection pipe 200 may be connected to the expansion unit 300.
확장부(300)는 상기 가이드관의 제1측 말단에 구비되며, 상기 공기주입관과 연결되어 공기를 제공받아 팽창된다. 예를 들어, 확장부(300)는 공기가 주입됨에 따라 특정한 크기와 특정한 형상으로 팽창되는 풍선일 수 있다. 확장부(300)는 팽창됨에 따라 협착병변부위의 일측에서 가이드관이 더 이상 협착병변부위 안쪽으로 진입하지 못하도록 막는 역할을 수행한다.The expansion unit 300 is provided at the end of the first side of the guide tube, and is connected to the air injection tube to be expanded by receiving air. For example, the expansion unit 300 may be a balloon that is expanded to a specific size and a specific shape as air is injected. The expansion part 300 serves to prevent the guide tube from entering into the stenosis any more in the stenosis lesion side as it expands.
공기주입기(400)는 신체외부에 위치하는 상기 가이드관의 제2측 말단에 구비되며, 상기 공기주입관을 통해 외부로부터 흡입한 공기를 상기 확장부(300)로 공기를 주입한다. 공기주입기(400)는 주사기 형상으로 형성될 수 있으나, 이에 한정되지 아니하고 공기를 주입할 수 있는 다양한 형상 또는 구조로 형성될 수 있다.The air injector 400 is provided at the second side end of the guide tube located outside the body, and injects air sucked from the outside through the air injection tube into the expansion part 300. The air injector 400 may be formed in a syringe shape, but is not limited thereto and may be formed in various shapes or structures capable of injecting air.
또한, 공기밸브(600);를 더 포함할 수 있다. 공기주입기(400)에 외부로부터 공기를 주입하고, 공기주입기(400)로부터 공기를 외부로 유출시키지 않고 확장부(300)로 주입하기 위해서는 공기의 흐름 경로를 조절하는 공기밸브(600)가 필요할 수 있다. 공기밸브(600)는 상기 가이드관의 제2측 말단에 구비되며, 제1방향으로 회전 시에 상기 공기주입관(200)과 상기 공기주입기(400)의 연결을 차단하고 외부공기의 유입이 가능하게 하고, 제2방향으로 회전 시에 상기 공기주입관(200)과 상기 공기주입기(400)를 연결하고 외부공기의 유입을 차단할 수 있다. 공기밸브(600)는 공기의 이동경로를 변경할 수 있는 다양한 구조로 형성될 수 있다.In addition, the air valve 600; may further include. In order to inject air from the outside into the air injector 400, and to inject the air from the air injector 400 to the expansion unit 300 without outflowing to the outside may require an air valve 600 for adjusting the flow path of the air have. The air valve 600 is provided at the second end of the guide tube, and blocks the connection between the air injection pipe 200 and the air injector 400 when it rotates in the first direction and allows the inflow of external air. And, when rotating in the second direction may connect the air injection pipe 200 and the air injector 400 and block the inflow of external air. The air valve 600 may be formed in various structures that can change the movement path of the air.
