Description

결찰용 실의 장력조절장치Tension control device for ligation thread
본 발명은 결찰용 실의 장력조절장치에 관한 것으로, 보다 상세하게는 혈관, 신경, 정관, 난관 등의 관형 조직을 주위 조직들로부터 박리(dissection) 및 결찰(ligation)하기 위하여 사용되는 결찰용 실의 장력을 조절할 수 있도록 하는 결찰용 실의 장력조절장치에 관한 것이다.The present invention relates to a tension control device of the ligation thread, and more particularly, a ligation seal used for dissection and ligation of surrounding tubular tissues such as blood vessels, nerves, vas deferens, and fallopian tubes from surrounding tissues. It relates to a tension control device of the ligation thread to be able to adjust the tension of.
일반적으로 혈관, 신경, 정관, 난관 등의 관형 조직을 결찰하기 위해서는, 주위 조직으로부터 분리하여야 하는데, 이때 주위 조직으로부터 분리하는 것을 박리라고 한다.In general, in order to ligation of tubular tissues such as blood vessels, nerves, vas deferens, fallopian tubes, etc., separation from surrounding tissues is required.
이와 같은, 박리를 위해서는 수술용 캘리 등의 도구를 이용하여 혈관 주위로 상,하,좌,우로 움직여 박리하는 방법을 사용하고 있는데, 이러한 경우 박리 도구에 의해 혈관이 손상될 우려가 높은 문제점이 있었다.In order to peel, such a method is used to move up, down, left, and right around a blood vessel using a tool such as a surgical caliber to remove the blood vessel. In this case, there was a high risk of damaging the blood vessel by the peeling tool. .
또한, 박리 후 결찰과정에 있어서 결찰하는 실의 장력이 너무 약하면 결찰의 효과가 발생되지 않고, 실의 장력이 너무 강하면 결찰하려는 조직이 손상될 우려가 크기 때문에 결찰하는 실의 장력을 조절할 수 있도록 하는 것이 매우 중요한데, 현재까지 결찰용 실의 장력을 조절할 수 있는 장치는 개발되고 있지 않은 실정이다.In addition, if the tension of the thread to be ligated in the ligation process after peeling is too weak, the effect of ligation does not occur, and if the tension of the thread is too strong, the tissue to be ligated is likely to be damaged. It is very important, but until now, a device that can adjust the tension of the ligation thread has not been developed.
한편, 이와 같은 결찰 시스템의 일실시예로 대한민국 공개특허공보 제10-2009-0033815호에는 내시경용 결찰구 및 내시경 결찰 시스템이 게재되어 있는데, 그 주요 기술적 구성은 도 1에 나타낸 바와 같이, 내시경의 삽입부(11)를 진퇴 가능하게 삽통시키는 삽통 루멘(21a)을 갖는 가요성 재료로 이루어지는 오버 튜브와, 오버 튜브의 선단부에 부착된 결찰용 O링(22)과, 결찰용 O링에 계지됨과 함께 기단측이 통상체 기단측으로 연장되고, 기단측이 인장 혹은 압출 조작됨으로써 결찰용 O링을 통상체의 선단으로부터 이탈시키는 조작 와이어(24)를 포함하여 이루어진다.Meanwhile, as an example of such a ligation system, Korean Patent Laid-Open Publication No. 10-2009-0033815 discloses an endoscope ligation port and an endoscope ligation system, and its main technical configuration is shown in FIG. The over tube made of a flexible material having an insertion lumen 21a for inserting and retracting the insertion portion 11 in advance, the O-ring 22 for ligation attached to the tip of the over tube, and the O-ring for ligation. Together, the proximal end extends to the normal proximal end, and the proximal end is extended or extruded to include an operation wire 24 for releasing the ligation O-ring from the distal end of the ordinary body.
상기 구성은 내시경의 충분한 시야를 확보하고, 내시경 삽입부 선단의 만곡 성능을 저하시키지 않도록 구성된 것에 특징이 있으나, 식도나 위에 형성된 정맥류의 결찰에만 사용될 수 있는 것이므로 조직을 박리시키는 것이 용이하지 않을 뿐만 아니라, 혈관의 결찰을 위해 혈관을 둘러싸고 있는 일부 조직까지 같이 결찰하여야 하고, 결찰을 위해 O링(22)을 사용하므로 결찰 장력을 조절하기가 어렵다는 문제점이 있다.The above configuration is characterized in that it is configured to ensure a sufficient view of the endoscope and not to reduce the bending performance of the end of the endoscope insertion portion, but because it can be used only for ligation of the varicose veins formed in the esophagus or stomach, it is not easy to detach the tissue. For ligation of blood vessels, the ligation of some tissues surrounding the blood vessels must be ligated together, and the O-ring 22 is used for ligation, which makes it difficult to control ligation tension.
또한, 대한민국 공개특허공보 제10-2007-0010912호 등에는 실의 장력을 조절할 수 있는 장치가 게재되어 있으나, 이들은 모두 재봉기에 사용되는 실의 장력을 조절하기 위한 것이므로, 구조가 복잡하고 결찰용 실의 장력조절에 사용하기가 어려운 단점이 있다.In addition, the Republic of Korea Patent Publication No. 10-2007-0010912 discloses a device that can adjust the tension of the thread, but these are all for controlling the tension of the thread used in the sewing machine, the structure is complicated and the ligation thread It is difficult to use to control the tension.

본 발명은 혈관, 신경, 정관, 난관 등의 관형 조직(50)을 주위 조직들로부터 박리(dissection) 및 결찰(ligation)하기 위하여 사용되는 결찰용 실(80)의 장력을 조절할 수 있도록 하는 결찰용 실의 장력조절장치(100)에 관한 것으로, 보다 상세히 설명하면, 초음파에 의한 영상이나 내시경을 통한 수술 시에 인체의 피부 내에 존재하는 혈관, 신경, 정관, 난관 등의 관형 조직(50)을 주위 조직들로부터 박리하여 결찰하는 경우, 안내도관인 시스(sheath)(60)를 이용하여 박리하고자하는 관형 조직(50)의 주위까지 박리도구(70)를 삽입하고, 박리도구(70)에 연결 설치된 결찰용 실(80)을 이용하여 관형 조직(50)을 감싼 후, 도 2에 나타낸 바와 같이, 시스(60)를 통해 박리도구(70)를 빼내면 관형조직(50)을 감싼 상태의 결찰용 실(80)이 인체의 외부로 빠져나올 수 있게 되는데, 본 발명에 따른 결찰용 실의 장력조절장치(100)는 이와 같이, 관형조직(50)(이하에서는 관형조직이 '혈관(50)'인 경우를 일례로 하여 설명하기로 한다.)을 감싼 상태에서 인체의 외부로 빠져나온 결찰용 실(80)의 장력을 조절하기 위해 사용되는 것이다.The present invention is for ligation to control the tension of the ligation seal 80 used for dissection and ligation of the tubular tissue 50, such as blood vessels, nerves, vas deferens, fallopian tubes from surrounding tissues Regarding the tension control device 100 of the thread, it will be described in more detail, surrounding the tubular tissue 50, such as blood vessels, nerves, vas deferens, fallopian tubes, etc. existing in the skin of the human body at the time of surgery through an ultrasound image or endoscope. In the case of ligation by peeling from the tissues, the peeling tool 70 is inserted to the periphery of the tubular tissue 50 to be peeled off using a sheath 60 as a guide conduit, and the ligation tool 70 is connected to the peeling tool 70. After wrapping the tubular tissue 50 using the chamber 80, as shown in FIG. 2, when the peeling tool 70 is pulled out through the sheath 60, the yarn for ligation is wrapped in the tubular tissue 50. 80 is able to escape to the outside of the human body, the present invention In accordance with the tension control device 100 of the ligation thread according to this, the tubular tissue 50 (hereinafter referred to as a case of the 'vascular vessel 50' will be described as an example.) It is used to adjust the tension of the ligation seal 80 exited to the outside.
즉, 상기 결찰용 실(80)을 이용하여 혈관(50)을 결찰하는 경우 혈액이 통과되지 못하도록 하기 위하여 혈관(50) 내로 혈액이 흐르도록 하는 혈압보다는 높은 압력으로 혈관(50)을 결찰하여야 하지만, 결찰 압력이 너무 높아지면 혈관(50)이 손상될 우려가 있으므로 혈압보다는 높으면서도 혈관(50)이 손상되지 않을 정도로 결찰압력을 조절할 수 있도록 하기 위하여 장력조절장치(100)를 사용하는 것이다.That is, when ligating the blood vessel 50 using the ligation seal 80, in order to prevent blood from passing through, the blood vessel 50 should be ligated at a higher pressure than blood pressure to allow blood to flow into the blood vessel 50. If the ligation pressure is too high, there is a risk that the blood vessel 50 may be damaged, so that the tension control device 100 is used to control the ligation pressure to a degree that is higher than the blood pressure so as not to damage the blood vessel 50.
상기와 같은 작용을 하는 본 발명에 따른 결찰용 실의 장력조절장치(100)는 도 3에 나타낸 바와 같이, 크게 하우징(110), 장력조절부(120) 및 손잡이(130)를 포함하여 이루어지는데, 상기 하우징(110)은 중공의 원통 형상으로 이루어져 그 내측에 장력조절부(120)가 설치될 수 있도록 하는 공간을 제공하는 역할을 하는 것이다.As shown in FIG. 3, the tension adjusting device 100 of the ligation thread according to the present invention having the above-described function includes a housing 110, a tension adjusting unit 120, and a handle 130. The housing 110 has a hollow cylindrical shape, and serves to provide a space for allowing the tension adjusting unit 120 to be installed therein.
다음, 상기 장력조절부(120)는 하우징(110)의 내측에 삽입 설치되어 손잡이(130)의 회전에 의해 결찰용 실(80)의 장력을 조절할 수 있도록 하는 역할을 하는 것으로, 혈관(50)을 감싼 상태로 인체의 외부로 빠져나온 결찰용 실(80)은 하우징(110)의 내측으로 투입되어 장력조절부(120)에 연결 설치된다.Next, the tension adjusting unit 120 is inserted into the housing 110 to serve to adjust the tension of the ligation seal 80 by the rotation of the handle 130, the blood vessel 50 The ligation seal 80 which escapes to the outside of the human body in a wrapped state is introduced into the housing 110 and is connected to the tension control unit 120.
이때, 상기 장력조절부(120)는 제1몸체(122)와 회전축(124), 제2몸체(126) 및 연결부재(128)를 포함하여 이루어지는데, 상기 제1몸체(122)는 하우징(110)의 내측 전방에 삽입 설치되어 결찰용 실(80)이 연결 설치될 수 있도록 하는 것으로, 이와 같은 결찰용 실(80)의 연결을 위해 하우징(110)의 전단부 내측에는 결찰용 실(80)이 관통되는 끼움고리(112)가 형성되고, 중공 형상으로 이루어진 제1몸체(122)의 내측에는 끼움고리(112)를 통과한 결찰용 실(80)이 연결 설치되는 원통형 고리(122a)가 설치된다.In this case, the tension adjusting unit 120 includes a first body 122, a rotating shaft 124, a second body 126 and the connecting member 128, the first body 122 is a housing ( It is inserted into the inner front of the 110 so that the ligation seal 80 can be connected to the installation, the ligation seal 80 inside the front end of the housing 110 for the connection of such ligation seal 80 A through ring 112 is formed therein, and a cylindrical ring 122a to which the ligation thread 80 passed through the fitting ring 112 is connected to an inner side of the first body 122 having a hollow shape. Is installed.
즉, 상기 장력조절부(120)는 제1몸체(122)의 전,후 이동을 통해 결찰용 실(80)의 장력을 조절할 수 있도록 구성된 것으로, 제1몸체(122)의 전,후 이동에 의해 결찰용 실(80)의 장력을 조절하기 위해서는 결찰용 실(80)이 폐루프를 이루도록 구성하여야 하는데, 상기 제1몸체(122)를 하우징(110)의 전방에 위치시킨 후, 하우징(110)의 내측으로 투입된 결찰용 실(80)의 양측 단부 중 일측 단부를 하우징(110)의 전단부에 설치된 끼움고리(112)를 통해 삽입하여 제1몸체(122)의 내측에 설치된 원통형 고리(122a)를 통해 돌아나오도록 한 후 결찰용 실(80)의 타측 단부와 묶어주면 결찰용 실(80)의 폐루프를 구성할 수 있게 된다.That is, the tension control unit 120 is configured to adjust the tension of the ligation thread 80 through the front and rear movement of the first body 122, to the front and rear movement of the first body 122 In order to adjust the tension of the ligation seal 80 by the ligation seal 80 should be configured to form a closed loop, after placing the first body 122 in front of the housing 110, the housing 110 The cylindrical ring 122a installed inside the first body 122 by inserting one end of both ends of the ligation seal 80 introduced into the inside through the fitting ring 112 provided at the front end of the housing 110. After returning through), if it is tied to the other end of the ligation chamber 80, the closed loop of the ligation chamber 80 can be configured.
한편, 상기와 같은 결찰용 실(80)의 폐루프를 보다 용이하게 구성할 수 있도록 하기 위하여, 도 5에 나타낸 바와 같이, 고정밴드(122b)와 고정고리(122c)를 사용할 수도 있는데, 상기 고정밴드(122b)는 제1몸체(122)의 원통형 고리(122a)에 걸림 결합되는 것이고, 상기 고정고리(122c)는 고정밴드(122b)의 양측 단부에 결합되어 결찰용 실(80)을 고정시킬 수 있도록 하는 역할을 하는 것이다.On the other hand, in order to more easily configure the closed loop of the ligation seal 80 as described above, as shown in Figure 5, it is also possible to use the fixing band 122b and the fixing ring 122c, the fixing The band 122b is engaged with the cylindrical ring 122a of the first body 122, and the fixing ring 122c is coupled to both ends of the fixing band 122b to fix the ligation seal 80. It is to play a role.
즉, 상기와 같이 원통형 고리(122a)에 고정밴드(122b)와 고정고리(122c)를 연결 설치하는 경우, 결찰용 실(80)의 양측 단부를 고정고리(122c)에 연결시키기만 하면 폐루프를 구성할 수 있게 되므로 장력조절장치(100)를 보다 편리하게 사용할 수 있게 된다.That is, in the case where the fixing band 122b and the fixing ring 122c are connected to the cylindrical ring 122a as described above, the closed loop only needs to connect both ends of the ligation seal 80 to the fixing ring 122c. Being able to configure the tension control device 100 can be used more conveniently.
또한, 고정고리(122c)에 연결 설치된 결찰용 실(80)의 양측 단부에 동일하지 않은 장력이 작용하는 경우에는, 원통형 고리(122a)의 회전에 의해 결찰용 실(80)과 고정밴드(122b)가 이루는 폐루프가 회전하게 되므로 상기 고정밴드(122b)와 고정고리(122c)에 의해 결찰용 실(80)의 양측 단부에는 항상 동일한 장력이 작용될 수 있게 된다.In addition, when unequal tension acts on both ends of the ligation seal 80 connected to the fixing ring 122c, the ligation seal 80 and the fixing band 122b are rotated by the rotation of the cylindrical ring 122a. Since the closed loop is rotated by the fixing band 122b and the fixing ring 122c, the same tension can always be applied to both ends of the ligation seal 80.
다음, 상기 회전축(124)은 일측 단부가 손잡이(130)의 내측에 끼움 결합되고, 타측 단부는 제2몸체(126)에 연결 설치되어 손잡이(130)의 회전에 의해 전,후로 구동하면서 제2몸체(126)를 전,후방으로 구동시키는 역할을 하는 것으로, 후술하겠지만 상기 손잡이(130)의 내주면에는 암나사(132)가 형성되고, 회전축(124)의 외주면에는 암나사(132)에 대응되는 수나사(124a)가 형성되어 손잡이(130)의 회전에 의해 회전축(124)이 회전하면서 제2몸체(126)를 전,후로 이동시킬 수 있도록 구성되어 있다.Next, the rotating shaft 124 is fitted with one end is fitted into the inside of the handle 130, the other end is connected to the second body 126 is installed to drive the front and rear by the rotation of the handle 130, the second It serves to drive the body 126 forward, backward, but will be described later, but the internal thread 132 is formed on the inner circumferential surface of the handle 130, the external thread corresponding to the female screw 132 on the outer circumferential surface of the rotating shaft 124 ( 124a is formed to rotate the shaft 124 by the rotation of the handle 130 is configured to move the second body 126 back and forth.

이는, 후술할 장력측정부(140)에서 측정되는 결찰용 실(80)의 장력을 보다 정확히 측정할 수 있도록 함과 동시에 결찰용 실(80)의 장력조절을 보다 미세하게 할 수 있도록 하기 위한 것으로 이에 대한 세부적인 내용은 후술하기로 하겠다.This is to make it possible to more accurately measure the tension of the ligation thread 80 measured by the tension measuring unit 140 to be described later, and at the same time to finely control the tension of the ligation thread 80. Details of this will be described later.
또한, 상기와 같이 텐션스프링(125)에 의해 제2몸체(126)의 전,후 구동이 제1몸체(122)로 전달되는 경우, 상기 연결부재(128)는 제1몸체(122)에는 고정 설치되지만, 제2몸체(126)에는 고정되지 않고 제2몸체(126)의 내측으로 단순 삽입되어 제1몸체(122)를 하우징(110)의 내부에서 지지하는 역할만을 하게 된다.In addition, when the front and rear driving of the second body 126 is transmitted to the first body 122 by the tension spring 125 as described above, the connecting member 128 is fixed to the first body 122 Although installed, it is not fixed to the second body 126 and is simply inserted into the second body 126 to support the first body 122 inside the housing 110 only.
