Description

지혈용 본 왁스 체내 주입장치Intra-body wax injection device for hemostasis
본 발명은 뼈수술에 따른 출혈을 정지시키기 위한 지혈장치에 관한 것으로서, 보다 상세하게는 지혈용 본 왁스(bone wax)를 체내 목표지점에 정확하게 도달시켜 신속하고 효율적인 지혈을 가능케 하는 지혈용 본 왁스 체내 주입장치에 관한 것이다. The present invention relates to a hemostasis device for stopping hemorrhage caused by bone surgery, and more particularly, to a hemostasis device for stopping hemostasis caused by bone surgery, more particularly, to a hemostatic wax body for achieving rapid and efficient hemostasis by accurately reaching a target point in a body Lt; / RTI >
수술시 뼈가 외과적으로 절단되는 경우, 뼈의 절단부위로부터 다량의 출혈이 발생하는 것은 흔한 일이다. 뼈에서 발생하는 출혈은 혈관에서 발생하는 출혈과는 달리 지혈이 어렵고 출혈양도 많은 경우가 대부분이다. 뼈로부터의 과도한 출혈은 수술 부위에 대한 시야를 나빠지게 함은 물론, 다급한 수혈을 필요로 하며, 나아가 수술 후 합병증을 유발할 수도 있다. 이러한 이유로 수술 중 뼈로부터의 출혈은 가급적 신속히 지혈하여야 한다.When the bone is surgically removed at the time of surgery, it is common that a large amount of bleeding occurs from the cutting site of the bone. Bleeding from the bone is difficult to hemostasis and hemorrhage is common, unlike hemorrhage in the blood vessels. Excessive hemorrhage from the bones will not only impair the field of view of the surgical site, but also require urgent transfusion and may lead to postoperative complications. For this reason, bleeding from the bone during surgery should be done as quickly as possible.
뼈로부터의 출혈을 감소시키거나 또는 멈추기 위한 방법으로서, 출혈부위에 본 왁스(Bone Wax)를 도포하여 출혈 구멍을 막는 방법이 전통적으로 적용되어 왔다. 상기 본 왁스는, 주재료인 밀랍과 연화재인 파라핀 또는 바셀린을 혼합하여 제작한 반고체 상태의 물질로서 적절한 도포수단을 통해 출혈부위에 도포된다.As a method for reducing or stopping the bleeding from the bone, a method of applying the wax to the bleeding site to block the bleeding hole has been conventionally applied. The present wax is applied to a bleeding site through a suitable application means as a semi-solid material produced by mixing wax, which is a main material, with paraffin or petrolatum, which is a softening material.
한편, 최소 침습수술(MIS, minimal invasive surgery) 관련 기술과 장비가 계속적으로 발전함에 따라, 과거에 환부를 절개하여야만 했던 많은 종류의 수술을, 절개 없이, 단지, 체내의 환부로 연결되는 통로를 확보하고 상기 통로를 통해 내시경과 치료기구를 삽입하여 치료하는 케이스가 점차 증가하고 있다.On the other hand, as the technology and equipment for MIS (minimally invasive surgery) continue to develop, many kinds of operations that had to be incised in the past are secured without incision, And a case where an endoscope and a therapeutic device are inserted through the pathway and treated is gradually increasing.
예컨대, 각종 척추관련 질환의 경우에도, 트로카(troca)를 이용해 등에 작은 구멍을 뚫고 척추의 병변 부위로 내시경과 치료도구를 삽입하여 치료를 하는 것이다. 그런데 척추 관련 수술의 많은 경우 척추뼈로부터의 출혈을 수반하므로, 척추뼈 내부로 상기 본 왁스를 효율적으로 주입하기 위한 주입장치가 필요하다.For example, in the case of various vertebral-related diseases, a trocar is used to puncture a small hole in the back, and an endoscope and a therapeutic instrument are inserted into a lesion portion of the vertebra.

이하, 본 발명에 따른 하나의 실시예를 첨부된 도면을 참조하여 보다 상세히 설명하기로 한다.Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
도 1 및 도 2는 본 발명의 제 1실시예에 따른 지혈용 본 왁스 체내 주입장치의 구성 및 사용 방식을 설명하기 위한 도면이다.FIG. 1 and FIG. 2 are views for explaining a configuration and a use method of a main wax intra-body injection device for hemostasis according to a first embodiment of the present invention.
도시한 바와 같이, 본 발명의 제1실시예에 따른 지혈용 본 왁스 체내 주입장치(10)는, 그 내부에 왁스(A)가 충전되는 주입헤드(11)와, 상기 주입헤드(11)의 후단부에 결합하며 주입헤드(11)의 내부로 압력을 인가하여 상기 왁스(A)를 압출시키는 압출수단으로서의 시린지(15)를 포함한다.As shown in the drawing, the main wax intra-body injection device 10 for hemostasis according to the first embodiment of the present invention includes an injection head 11 in which wax A is filled, And a syringe 15 as a pushing means for pushing out the wax A by applying pressure to the inside of the injection head 11 while being coupled to the rear end.
먼저, 상기 주입헤드(11)는, 일정직경을 가지며 길이방향으로 연장된 중공튜브형 중공바디(11a)를 포함하며, 상기 중공바디(11a) 내부에 왁스수용공간(11b)을 갖는다. First, the injection head 11 includes a hollow tube type hollow body 11a having a predetermined diameter and extending in the longitudinal direction, and has a wax receiving space 11b in the hollow body 11a.
상기 왁스수용공간(11b)의 내부에는 사용할 본 왁스(bone wax)가 충전된다. 상기 주입헤드(11)는 수술시 체내에 삽입되어 목표지점에 본 왁스를 전달하는 것이니 만큼, 사용 직전까지 멸균상태로 보관된다. 상기 주입헤드(11)는 합성수지나 금속으로 제작 가능하다.The wax receiving space 11b is filled with a bone wax to be used. Since the injection head 11 is inserted into the body at the time of surgery and transfers the wax to the target point, the injection head 11 is kept sterilized until immediately before use. The injection head 11 may be made of synthetic resin or metal.
상기 중공바디(11a)의 선단부에는 배출구(11c)가 마련되어 있다. 상기 배출구(11c)는 타원형 구멍으로서, 본 왁스(A)가 배출되는 통로이다. 상기 배출구(11c)의 모양이 타원형의 형태를 취하므로 배출되는 본 왁스의 폭이 넓다. 즉, 넓은 출혈부위(B)의 지혈에 효과적으로 사용될 수 있는 것이다.A discharge port 11c is provided at the tip of the hollow body 11a. The discharge port 11c is an elliptical hole, and is a passage through which the present wax A is discharged. Since the shape of the discharge port 11c takes an elliptical shape, the width of the wax to be discharged is wide. That is, it can be effectively used for hemostasis of a wide bleeding site (B).
특히 상기 배출구(11c)의, 일측부에는 유도로(11d)가, 반대편에는 누름부(11m)가 형성되어 있다. 상기 유도로(11d)는, 중공바디(11a)의 길이방향으로 배출되는 본 왁스의 일부를, 중공바디(11a)의 측방향, 즉 도 2의 화살표 a방향으로 유도하는 통로이다. 도 1에 도시되어 있는 유도로(11d)는 반원형의 형태를 취하지만, 유도로의 위치나 형상은 얼마든지 변경 가능하다.Particularly, the discharge port 11c has an induction passage 11d at one side thereof and a pressing portion 11m at the opposite side thereof. The guide passage 11d is a passage for guiding a part of the wax discharged in the longitudinal direction of the hollow body 11a to the side of the hollow body 11a, that is, in the direction of arrow a in Fig. The induction furnace 11d shown in Fig. 1 takes a semicircular shape, but the position and shape of the induction furnace can be changed as much as possible.
상기 유도로(11d)를 적용함으로서, 가령, 도 2에 도시한 바와 같이, 상기 본 왁스(A)를 압출하며 주입장치(10)를 화살표 z 방향으로 이동시킬 때, 본 왁스(A)가 최대한 신속하게 출혈부위(B)의 표면에 도포되게 된다. 더욱이 이 때 상기 유도로(11d)의 반대편에 위치한 누름부(11m)가 본 왁스를 내리 눌러 본 왁스를 최대한 출혈부위(B)로 집중시킨다.As shown in FIG. 2, when the main wax A is extruded and the injection device 10 is moved in the direction of the arrow z, the present wax A is maximally And is quickly applied to the surface of the bleeding part (B). At this time, the pressing portion 11m located on the opposite side of the guide path 11d concentrates the wax to the bleeding portion B as much as possible by pressing down the wax.
상기 출혈부위(B)는 출혈이 진행되고 있는 뼈의 표면으로서 본 왁스를 도포하기 위한 목표지점을 의미한다.The bleeding part (B) means the target point for applying the present wax as the surface of the bone on which bleeding is progressing.
도면부호 13은 마개이다. 상기 마개(13)는, 주입장치(10)를 사용하기 전 배출구(11c)에 끼워져 이물질의 유입을 차단하는 것으로서 신축성을 갖는 실리콘 등의 합성수지로 제작할 수 있다. Reference numeral 13 denotes a plug. The stopper 13 is inserted into the discharge port 11c before using the injection device 10 to block foreign matter from entering the stopper 13 and can be made of synthetic resin such as silicone having elasticity.
또한 상기 중공바디(11a)의 후단부에는 수나사부(11f)가 마련되어 있다. 상기 수나사부(11f)는 시린지(15)의 연결부(15c)와 나사 결합하는 부분이다. 상기 수나사부(11f)와 연결부(15c)는 얼마든지 착탈 가능하다.A male threaded portion 11f is provided at the rear end of the hollow body 11a. The male screw portion 11f is a portion that is screwed to the connecting portion 15c of the syringe 15. The male screw portion 11f and the connecting portion 15c can be attached or detached at any time.
아울러, 상기 수나사부(11f)의 전방부에는 한 쌍의 사이드탭(11e)이 일체로 형성되어 있다. 상기 사이드탭(11e)은 일정두께를 갖는 판상부재로서, 중공바디(11a)를 중심에 두고 반대편에 배치된다. 상기 사이드탭(11e)을 포함하는 가상의 평면은 중공바디(11a)의 중심축을 통과한다.In addition, a pair of side tabs 11e are integrally formed on the front portion of the male screw portion 11f. The side tab 11e is a plate-like member having a predetermined thickness, and is disposed on the opposite side with the hollow body 11a as the center. The virtual plane including the side tabs 11e passes through the central axis of the hollow body 11a.
특히 상기 사이드탭(11e)은 유도로(11d)의 위치를 알려주는 역할을 한다. 사실, 주입장치(10)의 사용 시, 상기 주입헤드(11)의 선단부가 체내에 삽입되므로, 사용자는 상기 유도로(11d)의 위치를 볼 수 없어 유도로(11d)를 출혈부위(B)에 대응시킬 수 없다. 효율적인 지혈작업을 할 수 없는 것이다.Particularly, the side tabs 11e serve to inform the position of the guide path 11d. The user can not see the position of the induction passage 11d so that the induction passage 11d can not be positioned at the bleeding site B because the distal end of the injection head 11 is inserted into the body when the injection device 10 is used, . You can not do efficient hemostasis.
그러나 본 발명의 주입장치(10)는 상기 사이드탭(11e)을 통해 유도로(11d)의 방향을 가늠할 수 있다.However, the injection apparatus 10 of the present invention can determine the direction of the guide path 11d through the side tabs 11e.
이를 위하여, 상기 사이드탭(11e)은, 사이드탭(11e)을 포함하는 가상의 평면이, 상기 유도로(11d)를 통한 본 왁스의 배출방향, 즉 화살표 a방향에 대해 수직을 이루도록 배치되는 것이다. 사용자는 상기 사이드탭(11e)이 중공바디(11a)의 양측에 수평을 유지함을 통해, 상기 유도로(11d)가 출혈부위(B)에 대응 배치되어 있음을 알 수 있다.To this end, the side tabs 11e are arranged so that a virtual plane including the side tabs 11e is perpendicular to the discharge direction of the wax through the guide path 11d, that is, the direction of the arrow a . The user can see that the guide channel 11d is arranged corresponding to the bleeding part B by keeping the side tabs 11e horizontal on both sides of the hollow body 11a.
경우에 따라 상기 사이드탭(11e)의 위치를, 사이드탭(11e)을 포함하는 가상의 평면이, 본 왁스의 배출방향과 평행하게 위치시킬 수도 있다. 즉, 도 1에 도시한 사이드탭(11e)을 90도 방향으로 위치 이동 할 수도 있는 것이다.In some cases, the position of the side tabs 11e may be positioned so that the imaginary plane including the side tabs 11e is parallel to the discharge direction of the present wax. That is, the side tab 11e shown in FIG. 1 may be moved in the 90-degree direction.
또한, 상기 사이드탭(11e)과 같은 목적을 갖는 별도의 표시를 마킹할 수도 있다. 이를테면 상기 중공바디(11a)의 외주면에 상기 왁스의 배출방향을 알려주는 표시를 인쇄할 수 있는 것이다.Further, a separate mark having the same purpose as the side tab 11e may be marked. For example, a mark indicating the discharge direction of the wax can be printed on the outer peripheral surface of the hollow body 11a.
여하튼 본 발명에 따른 사이드탭(11e)은, 중공바디(11a)의 배출구(11c)를 통해 배출되는 본 왁스(A)가 출혈부위(B)에 정확하고 효과적으로 도포되도록 가이드하는 역할을 한다.The side tab 11e according to the present invention serves to guide the wax A discharged through the discharge port 11c of the hollow body 11a accurately and effectively to the bleeding part B.
한편, 상기 시린지(15)는, 상기 수나사부(11f)에 착탈 가능하도록 나사 결합하는 배럴(15a)과, 상기 배럴(15a)의 내부로 진입하며 배럴(15a) 내부의 공기를 상기 왁스수용공간(11b)으로 이동시켜 상기 본 왁스를 압축시키는 플런저(15e)를 구비한다.The syringe 15 includes a barrel 15a that is threadably engaged with the male threaded portion 11f so as to be detachably engaged with the barrel 15a, And a plunger (15e) for moving the wax (11b) to compress the wax.
상기 배럴(15a)의 선단부에는 상기 수나사부(11f)에 나사 결합하는 연결부(15c)가 마련되어 있고, 상기 연결부(15c)의 중심부에는 관통로(15b)가 형성되어 있다. 상기 관통로(15b)는 배럴(15a) 내부의 공기가 왁스수용공간(11b)으로 공급되는 통로이다.The barrel 15a has a connecting portion 15c threadedly engaged with the male screw portion 11f and a through passage 15b formed at the center of the connecting portion 15c. The passage 15b is a passage through which air in the barrel 15a is supplied to the wax receiving space 11b.
상기 구성을 갖는 제1실시예에 따른 주입장치(10)를 이용하여 출혈부위(B)의 지혈을 하기 위해서는, 먼저, 상기 본 왁스가 채워져 있는 주입헤드(11)와 시린지(15)를 결합하고, 주입헤드(11)의 선단부를 목표지점인 출혈부위(B)에 접근 시킨다. 이 때 주입헤드(11)의 위치는 C-arm 등의 의료용 영상 촬영장치를 통해 실시간 체크된다.In order to perform hemostasis of the bleeding site B using the injection apparatus 10 according to the first embodiment having the above-described structure, first, the injection head 11 filled with the present wax is connected to the syringe 15 , The distal end portion of the injection head 11 approaches the bleeding portion B as the target point. At this time, the position of the injection head 11 is checked in real time through a medical imaging apparatus such as a C-arm.
상기 주입헤드(11)의 위치가 결정되었다면, 사이드탭(11e)의 방위를 참고하여 상기 유도로(11d)가 출혈부위(B)의 표면을 향하도록 한 후, 본 왁스(A)를 압출한다. 특히 출혈부위(B)가 넓을 경우에는, 상기 주입장치(10)를 화살표 z방향으로 이동시키며 출혈부위(B)의 표면에 본 왁스를 도포한다. 상기 과정을 통해 출혈부위에 도포된 본 왁스(A)는 출혈부위(B)의 미세 구멍을 막아 지혈 작용을 한다.If the position of the injection head 11 is determined, the guide path 11d is directed to the surface of the bleeding part B by referring to the orientation of the side tab 11e, and then the present wax A is extruded . In particular, when the bleeding part B is wide, the injection device 10 is moved in the direction of the arrow z and the wax is applied to the surface of the bleeding part B. The wax (A) applied to the bleeding site through the above process blocks the micropores of the bleeding site (B) to perform a hemostatic function.
도 3 및 도 4는 본 발명의 제 1실시예에 따른 지혈용 본 왁스 체내 주입장치(10)의 다른 구성 및 그 사용 방식을 설명하기 위한 도면이다.3 and 4 are views for explaining another configuration and a method of using the main wax intra-body injection device 10 for hemostasis according to the first embodiment of the present invention.
이하, 상기한 도면부호와 동일한 도면부호는 동일한 기능의 동일한 부재를 가리키며 반복되는 설명은 생략하기로 한다.Hereinafter, the same reference numerals as those of the above-mentioned reference numerals denote the same members having the same function, and a repeated description thereof will be omitted.
도면을 참조하면, 상기 중공바디(11a)의 선단부에 형성되어 있는 배출구(11k)가 일정 내경을 갖는 원형의 형태를 취함을 알 수 있다. 상기 도 1의 경우 배출구(11c)가 타원형이므로, 압출된 본 왁스(A)가 일정폭의 띠의 형태를 취하는 것에 비해, 상기 배출구(11k)를 통해 압출된 본 왁스(A)는 매우 좁은 실선의 형태를 취한다. 상기 압출의 횟수를 조절함에 따라 실선이 아니라 점선 또는 스폿(spot)의 형태가 될 수도 있다.Referring to the drawing, it can be seen that the discharge port 11k formed at the tip of the hollow body 11a takes a circular shape having a certain inner diameter. In the case of FIG. 1, since the outlet 11c is elliptical, the wax A extruded through the outlet 11k has a narrow narrow solid line, . As the number of times of extrusion is adjusted, it may be a dotted line or a spot instead of a solid line.
도 3에 도시한 타입의 주입헤드(11)는 미세 지혈에 사용할 수 있는 타입의 것이다. 즉, 본 왁스(A)를 스폿(spot) 형태로 압출시켜 미세출혈 부위에만 도포하는 것이다.The injection head 11 of the type shown in Fig. 3 is of a type that can be used for microfiltration. That is, the present wax (A) is extruded in a spot form to be applied only to a micro bleeding site.
또한 상기 배출구(11k)의 일측에는, 중공바디(11a)의 전방으로 돌출된 누름부(11m)가 마련되어 있다. 상기 누름부(11m)는, 중공바디(11a)로부터 토출되는 본 왁스(A)를 출혈부위(B) 측으로 눌러 가압하는 역할을 한다. 예컨대 도 4에 도시한 바와 같이, 상기 배출구(11k)로부터 배출되는 본 왁스를 화살표 a방향으로 유도하며 가압하는 것이다.In addition, a pushing portion 11m protruding forward of the hollow body 11a is provided at one side of the discharge port 11k. The pressing portion 11m functions to press the main wax A discharged from the hollow body 11a toward the bleeding portion B side. For example, as shown in Fig. 4, the present wax discharged from the discharge port 11k is guided in the direction of arrow a and pressurized.
아울러 상기 누름부(11m)는 본 왁스(A)를 절단하는 기능도 갖는다. 이를테면, 원하는 양의 본 왁스(A)가 토출된 후 주입장치(10)를 화살표 c방향으로 재껴 올리면, 누름부(11m)의 선단 에지라인이 출혈부위(B)를 향하여 하강하며 토출된 본 왁스(A)를 끊는 것이다. 상기한 스폰(spot) 형태의 압출이 가능한 구조이다.In addition, the pressing portion 11m also has a function of cutting the present wax A. For example, when the desired amount of the wax A is discharged and then the injection device 10 is raised in the direction of the arrow c, the leading edge line of the pressing portion 11m descends toward the bleeding portion B, (A). It is a structure capable of extrusion of the spot type described above.
도 5는 본 발명의 제1실시예에 따른 지혈용 본 왁스 체내 주입장치에서의 주입헤드(11)를 별도로 도시한 사시도이고, 도 6은 상기 주입헤드(11)의 사용방식을 설명하기 위한 도면이다.FIG. 5 is a perspective view showing the injection head 11 in the main wax injection device for hemostasis according to the first embodiment of the present invention, and FIG. 6 is a view for explaining a method of using the injection head 11 to be.
도면을 참조하면, 상기 중공바디(11a)의 선단부에 형성되어 있는 배출구(11r)가 대략 사각형의 형태를 취함을 알 수 있다. 말하자면, 상기 배출구(11r)의 일부는 중공바디(11a)의 길이방향 선단부를 향하고 나머지 일부는 측방향으로 개방된 것이다.Referring to the drawing, it can be seen that the discharge port 11r formed at the tip of the hollow body 11a has a substantially rectangular shape. In other words, a part of the discharge port 11r is directed toward the longitudinal end portion of the hollow body 11a and the remaining portion is opened laterally.
배출구(11r)를 상기한 형상으로 적용함으로서, 본 왁스(A)의 압출 방향이 중공바디(11a)의 길이방향에 대해 경사질 수 있다. 즉, 출혈부위(B)의 표면에 대한 중공바디(11a)의 사이각(θ)을 작게 유지하더라도, 출혈부위(B)에 대한 본 왁스의 원활한 도포가 이루어질 수 있는 것이다.By applying the discharge port 11r in the above-described shape, the extrusion direction of the present wax A can be inclined with respect to the longitudinal direction of the hollow body 11a. That is, even if the angle? Of the hollow body 11a with respect to the surface of the bleeding region B is kept small, the wax can be smoothly applied to the bleeding region B.
