결석 제거 장치Stone removal device
본 발명은 결석크기를 가늠할 수 있는 결석 제거장치에 관한 것으로, 더욱 상세하게는 인체 내부의 결석을 포획하기 위해 근접하는 가이드튜브, 바스켓 또는 파쇄프로브 등에 결석의 크기를 가늠할 수 있는 크기가늠자를 구비하거나, 내시경부의 카메라로 촬영된 영상에 결석의 크기를 가늠할 수 있는 크기가늠자를 증강현실로 표시하여, 내시경을 통해 상기 크기가늠자로 포획하기 전의 결석 크기를 가늠할 수 있어, 결석제거 시술시간이 단축됨은 물론, 결석 제거가 용이한 결석 제거장치에 관한 것이다.The present invention relates to a stone removal apparatus capable of measuring the size of a stone, and more specifically, to provide a size scale capable of measuring the size of a stone, such as a guide tube, a basket or a crushing probe that is close to capture the stone inside the human body. In addition, by displaying the size scale capable of measuring the size of the stones in the image taken by the camera of the endoscope with augmented reality, the size of the stones before being captured by the size scale can be measured through the endoscope, thereby reducing the time required for removing stones. , It relates to a stone removal device that is easy to remove stones.
일반적으로 인체 내부의 분비물에 포함된 염류가 이물(異物)의 표면이나 작은 결정괴(結晶塊) 주변에 붙어서 돌같이 굳은 생성물을 결석(calculus)라 한다.In general, salts contained in secretions inside the body are attached to the surface of a foreign body or around a small crystal nucleus, and a product hardened like a stone is called a calculus.
결석은 유기질 이온이 pH의 변화에 따른 용해도 변화에 의해 침착되는 것으로 알려져 있는데, 상기 결석이 생성되는 부위에 따라, 담낭(쓸개) 속에 생긴 결석인 담석(gallstone)과, 요로에 생기는 결석인 요석이 주를 이룬다.It is known that organic ions are deposited by changing the solubility of organic ions according to a change in pH. Depending on the site where the stones are generated, gallstones, which are stones formed in the gallbladder (gallbladder), and urolithiasis, which are stones in the urinary tract, are formed. Main week.
이러한 결석은 체내 정상적인 흐름에 장애를 유발하기 때문에 제거할 필요가 있는데, 결석의 크기가 매우 작은 경우에는 내시경을 통하여 생리 식염수를 주입하여 결석을 세척할 수도 있으나, 결석이 큰 경우에는 외과 수술이나 내시경에 장착된 다양한 형태의 집게 또는 바스켓을 이용하여 물리적으로 결석을 제거하는 방법이 있다.These stones need to be removed because they cause disorders in the normal flow in the body. If the size of the stones is very small, physiological saline may be injected through the endoscope to wash the stones, but if the stones are large, surgical or endoscopy There is a method of physically removing stones by using various types of forceps or baskets mounted on the.
이하 종래 기술에 따른 바스켓을 이용한 결석 제거 도구를 살펴본다. 대표적으로 한국특허공개 제10-1999-0068475호, 제10-2005-0032634호, 및 제10-2008-0095061호에 나타난 바와 같이, 대부분의 바스켓은 4개의 와이어로 구성되고, 각 와이어가 시작점과 종결점에서 서로 연결되어 있는 구조를 가진다. 와이어가 내시경튜브 밖으로 인출될 때 각 와이어가 사방으로 팽창하면서 내부에 포획공간을 마련하고 이 포획공간에 결석을 포획하여 체외로 결석을 추출하는 구성을 가진다.Hereinafter, a tool for removing stones using a basket according to the related art will be described. Representatively, as shown in Korean Patent Publication Nos. 10-1999-0068475, 10-2005-0032634, and 10-2008-0095061, most baskets are composed of four wires, and each wire has a starting point and It has a structure that is connected to each other at the end point. When the wire is pulled out of the endoscope tube, each wire expands in all directions to provide a trapping space therein and capture the stones in the trapping space to extract the stones out of the body.
상기와 같이 포획된 결석을 체외로 추출하기 위해서는 와이어가 결석을 포획한 상태에서 와이어를 안내하는 내시경튜브와 함께 체외로 추출하는데, 이때 결석의 크기가 내시경튜브의 직경보다 크게 되면, 결석을 체외로 추출할 시, 내시경의 직경보다 큰 결석의 크기에 의해 담관, 요도, 요관 등과 같은 관상의 생체관 내측벽이 무리하게 확관되어 관상의 생체관이 찢어지는 등의 문제가 발생하였고, 결석의 크기가 너무 크면, 체외로 추출할 수 없어, 체내에서 파쇄수단으로 결석을 파쇄 후, 파쇄된 작은 크기의 결석을 추출하였다.In order to extract the captured stones as in vitro, the wire is extracted with the endoscope tube guiding the wire in the state of capturing the stones, and when the size of the stones is greater than the diameter of the endoscope tube, the stones are removed from the body. When extracting, due to the size of the stones larger than the diameter of the endoscope, problems such as tearing of the tubular biotubes occurred due to excessive expansion of the inner wall of the tubular biotubes such as bile ducts, urethra, and ureters. If it is too large, it cannot be extracted out of the body, and after crushing the stones with the crushing means in the body, the crushed small-sized stones were extracted.
이때 결석의 추출과정 중 체외에서 체내에 있는 결석의 크기를 정확하게 판단할 수 없어 결석을 포획하고 파쇄한 후, 결석 크기를 다시 가늠하는 등의 과정이 연속반복 실시되어 결석을 제거하는 시술시간이 예정 시간보다 오래 걸리는 등의 문제점이 발생했을 뿐만 아니라, 내시경튜브의 직경과 비슷한 크기의 파쇄된 결석에 형성된 모서리에 의해 담관, 요도, 요관 등과 같은 관상의 생체관 내측벽이 긁혀 출혈이 발생하는 등의 문제가 있었다.At this time, during the extraction process of the stones, the size of the stones in the body cannot be accurately determined from outside the body, and the procedures such as capturing and crushing the stones and measuring the size of the stones again and again are continuously repeated to remove the stones. Not only did it cause problems such as taking longer than time, but the inner wall of the tubular biotubes, such as the bile duct, urethra, and ureter, was scratched by edges formed in crushed stones having a size similar to the diameter of the endoscope tube. There was a problem.
