본 발명은 오버튜브에 관한 것으로, 더 상세하게는 오버튜브로서의 역할은 물론 오버튜브의 끝단에 결찰 가능한 기술적 구성을 구비함과 아울러, 그 결찰 가능한 기술적 구성을 보호하면서 병변 부위를 포커싱(focusing) 하도록 오버튜브의 직경 보다 큰 직경으로 탈착 가능한 가이드 캡을 포함함에 따라 비교적 큰 직경의 병변도 간단하게 결찰 한 후 절제가 이루어질 수 있도록 한 오버튜브에 관한 것이다. The present invention relates to an overtube, and more particularly, to an overtube having a technical structure capable of being ligated to an end of an overtube as well as an overtube, and focusing on a lesion site while protecting the ligation- The present invention relates to an overtube which can be easily resected after ligating even a relatively large diameter lesion by including a guide cap detachable with a diameter larger than the diameter of the overtube.
일반적으로 내시경(Endoscope)은 수술이나 부검과 같은 신체의 개복이나 절개 없이 소형 카메라를 이용하여 내장 장기 또는 체강 내부를 관찰하여 그 이상 여부를 확인할 수 있는 장비이다. In general, an endoscope is a device for observing the internal organs or internal parts of a body cavity using a small-sized camera, without having to open or incise the body such as surgery or autopsy.
이러한 내시경은 통상적으로 인체의 내부의 굴곡을 따라 휘어질 수 있도록 오버튜브에 끼워져서 사용된다. 즉, 오버튜브는 수술장비와 함께 사용되는 도구로서, 수술장비가 신체의 원하는 위치로 가이드 할 수 있도록 사용된다. Such an endoscope is usually used by being fitted in an overtube so that it can be bent along the internal bending of the human body. That is, an overtube is a tool used with a surgical instrument, which is used to guide the surgical instrument to a desired position in the body.
아울러, 내시경은 병변 부위를 관찰함과 아울러 밴드 결찰 할 수 있는 기술적 구성도 포함하는 것으로, 즉 대한민국 등록 특허공보 제10-0548873호(이하 '선행기술문헌 1'이라 한다)에 게시된 바와 같이 내시경의 선단에 결합되는 몸체에 각각의 실에 의해 순차적으로 병변 부위를 결찰 할 수 있는 복수의 밴드가 마련되는 밴드 결찰기와 같은 기술적 구성도 포함할 수 있다. In addition, the endoscope includes a technical structure for observing a lesion site and ligating a band, that is, as disclosed in Korean Patent Registration No. 10-0548873 (hereinafter referred to as "Prior Art Document 1"), And a band ligation unit having a plurality of bands capable of sequentially ligating the lesion sites by respective yarns to the body coupled to the distal end of the band ligation unit.
여기서, 통상적인 내시경은 비교적 가늘고 길게 형성되면서 작은 직경을 가짐은 물론 상기 내시경의 선단에 마련되는 밴드 결찰기 또한 내시경의 직경과 거의 대등소유한 직경을 가짐에 따라 작은 직경을 가지는 병변의 결찰은 용이하게 이루어질 수 있었다. Here, a conventional endoscope has a relatively small diameter and a relatively small diameter, and the band ligature provided at the end of the endoscope has a diameter substantially equal to the diameter of the endoscope, so that the ligature having a small diameter can be easily ligated .
그러나 내시경보다 큰, 즉 통상적인 내시경은 0.58 내지 17.78㎜의 외경을 가짐에 따라 대략 2㎝ 이상의 큰 직경을 가지는 병변을 결찰 할 수 없는 단점을 가진다. 이때, 통상적인 오버튜브는 내시경의 단면적에 비하여 적어도 3배 이상의 넓은 단면적을 가진다. However, a larger endoscope, that is, a conventional endoscope has an outer diameter of 0.58 to 17.78 mm, and has a disadvantage that it can not ligate a lesion having a large diameter of about 2 cm or more. At this time, the conventional overtube has a cross-sectional area at least three times larger than the cross-sectional area of the endoscope.

As described in Korean Patent Registration No. 10-1563175 (hereinafter referred to as " Prior Art Document 2 "), the overtube is composed of a plurality of layers, and the flexible region and the non- A technique has been proposed in which strengths of regions are made different from each other so that unnecessary bending is not caused when the flexible region is bent.
또한, 대한민국 등록 특허공보 제10-1696696호(이하 '선행기술문헌 3'이라 한다)에 게시된 바와 같이 체강으로부터 원하지 않는 물질을 제거하고, 체강에 유체를 전달시키기 위한 흡입-세척 시스템에서 카테터의 세척 팁을 사용하는 오버튜브와 같은 기술도 제안된 바 있다. In addition, as disclosed in Korean Patent Registration No. 10-1696696 (hereinafter referred to as "Prior Art Document 3"), in a suction-cleaning system for removing unwanted substances from the body cavity and delivering fluid to the body cavity, Techniques such as overtube using cleaning tips have also been proposed.

At this time, the tip of the guide cap protrudes more than the tip of the overtube. That is, the tip of the overtube does not directly touch the lesion site, but the tip of the guide cap contacts the lesion site first.
간격 유지턱부(10)는 가이드 캡(30)의 내측면 사이와 오버튜브(1)의 외측면 사이에 밴드 결찰부(20)의 복수의 밴드(22)가 그 오버튜브(1)의 외측면으로 결합 될 수 있는 공간을 형성하기 위한 역할과 함께 가이드 캡(30)을 탈착할 수 있는 역할을 겸한다. The gap holding jaw 10 is provided with a plurality of bands 22 of the band ligation portion 20 between the inner side surfaces of the guide cap 30 and the outer side surface of the overtube 1, And the guide cap 30 can be detached and attached.
오버튜브(1)의 끝단에는 통상적인 플랜지부(1A)를 일체로 형성하거나 혹은 별도로 형성하여 공지된 방식에 의해 결합 가능한 구조를 형성하여도 무방하며, 유연성을 가지는 통상적인 합성수지로 제작되는 것이 바람직하다. A conventional flange portion 1A may be integrally formed at the end of the overtube 1 or may be formed separately so as to form a structure that can be engaged by a known method. Preferably, the overtube 1 is made of a general synthetic resin having flexibility Do.
밴드 결찰부(20)는 오버튜브(1)의 선단 측의 외측면에 결합된 복수의 밴드(22)와 그 복수의 밴드(22)와 엮어진 각각의 실(24)을 상기 오버튜브(1)의 끝단 혹은 플랜지부(1A)의 외부에서 각 실(24)의 인출로 인해 병변 부위로 각 밴드(22)에 의해 결찰한다. 상기 실(24)은 통상적인 제어기(26)에 의해 인출된다. The band ligating unit 20 includes a plurality of bands 22 coupled to the outer surface of the distal end side of the overtube 1 and respective yarns 24 interlaced with the plurality of bands 22 to the overtube 1 Or the outside of the flange portion 1A due to the withdrawal of the respective chambers 24 by the respective bands 22 as shown in Fig. The chamber 24 is withdrawn by a conventional controller 26.
여기서, 밴드 결찰부는 발명의 배경기술에 기재한 선행기술문헌 1과 동일한 기술적 구성과 작용효과를 가지는 것이므로 구체적인 기술적 구성과 작용 효과에 대하여 상세한 설명은 생략한다. Here, since the band ligation portion has the same technical structure and operation effect as the prior art document 1 described in the background art of the invention, detailed description of the technical structure and operation effects will be omitted.
간격 유지턱부(10)와 가이드 캡(30)의 탈착은 공지된 서로 대응되는 위치에 형성되는 나선에 의한 나사 결합방식의 회전 또는 가이드 홈과 돌기에 의한 슬라이딩과 회전에 의해 탈착 가능하게 마련된다. 이때, 상기한 방식 이외에 간격 유지턱부로부터 가이드 캡을 탈착 할 수 있는 공지된 어떠한 구조를 적용하여도 무방하다. The gap holding jaw 10 and the guide cap 30 are detachably attached to each other by a screw-type rotation or a guide groove and a projection, which are formed at known positions corresponding to each other. At this time, any known structure capable of detaching the guide cap from the gap holding jaw may be applied in addition to the above-described method.
또한, 상기 간격 유지턱부(10)는 오버튜브(1)의 외측면에 그 오버튜브(1)를 제작시 일체로 형성되거나 혹인 통상적인 방식인 나사 결합방식 등에 의해 탈착 가능하게 마련하여도 무방하다. The gap holding jaw 10 may be integrally formed on the outer surface of the overtube 1 when the overtube 1 is manufactured or may be detachably attached to the outer surface of the overtube 1 by a conventional screw coupling method or the like .
상기와 같이 구성됨에 따라 먼저, 오버튜브의 선단 외측면에 결찰 할 있도록 복수의 밴드를 결합한 후 실은 오버튜브의 내부를 통하여 끝단 측에 위치하는 제어기에 연결된다. According to the above-described structure, first, the plurality of bands are coupled so as to be ligated to the outer surface of the tip of the overtube, and then the yarn is connected to the controller located at the end side through the inside of the overtube.
그런 다음 가이드 캡의 끝단 내측면을 간격 유지턱부에 통상적인 방식인 나사 결합방식 또는 슬라이딩 후 회전에 의해 결합 고정한다. 이때, 상기 가이드 캡은 밴드 결찰부의 밴드를 보호하는 역할을 겸한다. Then, the inner surface of the end portion of the guide cap is engaged and fixed to the gap maintaining jaw by a screw coupling method or a post-sliding rotation. At this time, the guide cap also serves to protect the band of the band ligation part.
그리고 나서 상기 가이드 캡을 제거하고자 하는 병변 측으로, 즉 기존의 내시경에서 제거할 수 없는 크기를 가지는 큰 직경을 가지는 병변 측으로 가이드 하면서 포커싱 한다. 즉, 가이드 캡은 내시경 보다 적어도 단면적이 3배 이상 넓은 면적으로 가지는 오버튜브 보다 더 넓은 단면적을 가짐에 따라 비교적 넓은 직경을 가지는 병변의 주변으로의 포커싱이 안정적이면서 정확하고 용이하게 이루어질 수 있는 조건을 가질 수 있다. Then, the guide cap is guided to the side of the lesion to be removed, that is, to the side of the lesion having a large diameter which can not be removed from the existing endoscope. That is, since the guide cap has a wider cross-sectional area than an overtube having an area at least three times larger than that of an endoscope, it is possible to stably and accurately perform focusing on a lesion having a relatively large diameter Lt; / RTI >
다시 말해서, 내시경에서 크기 때문에 제거하지 못하였던 비교적 큰 직경을 가지는, 즉 대략 2㎝ 전,후의 병변을 본 발명은 오버튜브를 사용하여 병변을 결찰할 수 있도록 함으로써, 절개 수술 없이도 원활한 수술이 이루어질 수 있는 것이다. In other words, according to the present invention, lesions can be ligated using an overtube, which has a relatively large diameter, that is, about 2 cm before and after, which can not be removed due to its size in the endoscope. It is.
즉, 먼저 가이드 캡의 선단을 병변 주변으로 포커싱하여 접촉되도록 한 후, 오버튜브의 내부로 유입된 수술도구 중의 하나인 집게 도구 등에 의해 병변 부위를 잡고 인입시킴에 따라 오버튜브와 대응되는 크기의 병변이라도 원활하게 인입될 수 있는 것이다. 이때, 병변 부위는 오버튜브를 통한 내시경에 의해 관찰된 상태에서 이루어진다. That is, the tip of the guide cap is first focused on the periphery of the lesion, and then the lesion is brought into contact with the lesion by one of the surgical instruments introduced into the overtube, It is possible to enter smoothly. At this time, the lesion site is observed with the endoscope through the overtube.
이렇게, 가이드 캡을 거쳐 오버튜브의 선단 내부로 비교적 큰 직경을 가지는 병변 부위가 인입된 후에는 그 오버튜브의 선단의 외측면에 결합되어 있는 복수의 밴드가 밴드 결찰부에 의하여 적오도 1번 이상의 결찰하게 된다. 적정하게는 2번 정도의 밴드 결찰이 이루어질 수 있도록 하는 것이 바람직하다. After the lesion portion having a relatively large diameter is introduced into the distal end of the overtube through the guide cap, a plurality of bands coupled to the outer surface of the distal end of the overtube are retracted one or more times It will lead. It is preferable that the band ligation is performed twice or more.
이때, 상기 밴드 결찰부(20)는 오버튜브(1)의 외측면에 결합된 복수의 밴드(22)와 그 복수의 밴드(22)와 엮어진 각각의 실(44)을 그 오버튜브(1)의 끝단이나 그 끝단에 형성된 플랜지부(1A)의 외부에서 각 실(24)의 인출로 인해 병변 부위로 각 밴드(32)에 의해 결찰하는 것이다. 상기 실은 통상적인 제어기(26)에 의해 인출된다. The band ligation unit 20 includes a plurality of bands 22 coupled to the outer surface of the overtube 1 and respective yarns 44 interlaced with the plurality of bands 22 to the overtube 1 And each of the seams 24 is led out from the outside of the flange portion 1A formed at the end or end of the flange portion 1A. The yarn is drawn out by a conventional controller 26.
아울러, 병변 부위에 밴드에 의해 결찰 된 후에는 다시 오버튜브나 혹은 내시경에 구비된 절제 도구에 의해 절제되고, 그 절제와 동시에 공지된 방식에 의해 절제된 부위에 클립을 이용하여 재차 봉합하는 작업을 수행한다. 이때, 클립에 의한 봉합은 내시경 수술에서 행하여지는 동일한 방법을 적용할 수 있을 뿐만 아니라 상기 본 발명의 오버튜브를 통하여 통상적인 수술도구인 클립 도구에 의해 봉합하여도 무방하다. In addition, after ligating by a band on the lesion site, it is resected by a resection tool provided in an overtube or an endoscope. At the same time as the resection, a clipping operation is performed using a clip on the resected site do. At this time, not only the same method as in the endoscopic surgery can be applied to clip-closure, but it is also possible to seal the clips by means of a clip tool that is a conventional operation tool through the overtube of the present invention.
이로써, 본 발명의 오버튜브는 내시경에 의해 처리하지 못하는 비교적 큰 직경을 가지는 병변 부위를 그 오버튜브 내로 인입 한 후 밴드 결찰부에 의해 결찰 한 다음 절제와 봉합을 순차적으로 행함으로써, 내시경에서 해결하지 못하는 비교적 큰 직경을 가지는 병변 부위의 수술이 번거롭거나 불편함 없이 용이하게 이루어질 수 있는 조건을 가진다. Thus, the overtube according to the present invention can be applied to an endoscope in which a lesion having a relatively large diameter which can not be processed by an endoscope is drawn into the overtube, ligated by a band ligation unit, The operation of the lesion portion having a relatively large diameter that can not be performed is easily performed without inconvenience or inconvenience.
이는 오버튜브의 특성상 내시경의 단면적에 비하여 적어도 3배 이상의 넓은 단면적을 가짐에 따라 가능하다 할 것이다. This will be possible because of the characteristic of the overtube, as it has a cross-sectional area at least three times larger than the cross-sectional area of the endoscope.
더욱이, 오버튜브의 선단에 그 오버튜브 보다 더 큰 직경을 가지는 가이드 캡에 의해 병변으로의 포커싱이 안정적이면 정확하게 이루어질 수 있어, 결착 작업이 더욱더 용이하게 이루질 수 있음은 물론 그 후의 수술작업 또한 원활하게 이루어질 수 있는 조건도 가진다. Further, since the guide cap having a diameter larger than that of the overtube at the tip of the overtube can be accurately and accurately focused on the lesion, it is possible to more easily perform the binding operation, It also has conditions that can be achieved.
참고로, 본 발명의 오버튜브에는 절제 기구와 봉합 기구를 인입과 인출을 반복하여 사용하는 것이 아니라 그 오버튜브 자체에서 절제 기구와 봉합 기구를 동시에 사용할 수 있는 기술적 구성을 가질 수 있도록 지속적인 연구개발이 요구된다. For reference, continuous research and development is carried out so that the overtube of the present invention can have a technical configuration that can use the resection mechanism and the suturing mechanism simultaneously in the overtube itself, instead of using the resection mechanism and the suturing mechanism repeatedly. Is required.
