Wound indicators can be inserted directly into the affected part of the patient, such as a tumor, so that the exact location is known for radiation therapy or surgery. The affected area indicator is made of a metal coil having an inner diameter of about 0.3 mm, an outer diameter of about 0.5 mm, and a length of about 5 mm. The reason why the affected area is made of metal is to show the position clearly during X-ray, ultrasonography or radiography, and to produce the coil (spring) in order to prevent it from moving or moving when inserted into the affected area. For sake.
도 1은 종래의 주사기에 환부표시기를 끼운 상태의 측단면도이다. 도 1에 도시된 바와 같이, 주사기(13) 앞부분에 주사바늘(또는 시스, Sheath)(12)이 끼워지고, 주사기(13) 내부에는 코어(14)가 위치한다. 도 1과 같은 주사기를 일명 코어 니들 푸쉬형 주사기라고 한다.1 is a side cross-sectional view of a conventional syringe with the affected area fitted. As shown in FIG. 1, a needle (or sheath) 12 is inserted in front of the syringe 13, and a core 14 is positioned inside the syringe 13. A syringe such as FIG. 1 is called a core needle push type syringe.
이와 같은 코어 니들 푸쉬형 주사기는 다음과 같은 방법으로 사용되었다. 먼저, 주사기(13)와 환부표시기(2)를 각각 별도로 준비한다. 그 다음, 손이나 핀셋 등으로 주사바늘(12) 내부로 환부표시기(2)를 삽입한다. 그 다음, 코어(14)를 살짝 밀어 넣어 준비과정을 완료한다.This core needle push syringe was used in the following manner. First, the syringe 13 and the affected area indicator 2 are separately prepared. Then, the affected area indicator 2 is inserted into the needle 12 by hand or tweezers. Then, slightly push the core 14 to complete the preparation process.
실제, 환부표시기(2)를 삽입할 때에는 주사바늘(12)을 환부에 찌른 다음 코어(14)를 밀어 환부표시기(2)를 삽입한다. In fact, when inserting the affected area indicator 2, the needle 12 is inserted into the affected area, and then the core 14 is pushed to insert the affected area indicator 2.
그러나, 이와 같은 종래의 환부표시기(2)와 코어 니들 푸쉬형 주사기는 다음과 같은 불편한 점이나 단점이 있었다.However, the conventional affected area indicator 2 and the core needle push-type syringe have the following inconveniences and disadvantages.
첫째, 환부표시기의 외경이 약 0.5 mm로서 매우 작기 때문에, 손이나 핀셋으로 취급이 불편하고, 주사바늘 내부에 삽입하는 준비과정이 번거로웠다.First, since the outer diameter of the affected area indicator is about 0.5 mm, which is very small, it is inconvenient to handle with a hand or tweezers, and the preparation process for inserting into the needle is cumbersome.
둘째, 삽입된 환부표시기가 주사바늘 내부에서 움직이거나 빠질 수 있기 때문에 주사기를 수평으로 유지해야 하는 등 취급이 까다로웠다.Second, since the inserted lesion indicator may move or fall inside the needle, handling of the syringe has to be kept horizontal.
셋째, 환부가 인체 내부에 있기 때문에 주사바늘을 찌를 때 바늘 내부로 다른 조직이나 물질이 들어오는 문제점이 있었다.Third, since the affected part is inside the human body, there was a problem that another tissue or material enters the needle when the needle is pierced.
넷째, 위와 같은 경우, 환부의 생검을 필요로 하는 경우가 많은데, 이 때 별도의 생검용 주사바늘을 이용해야 하기 때문에 두번에 걸쳐 주사바늘을 찔러야 하는 단점이 있었다.Fourth, in the case of the above, there are many cases that require a biopsy of the affected area, but at this time, a separate biopsy needle has to be used, which has the disadvantage of having to stab the needle twice.
따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 제 1 목적은, 환부표시기가 주사바늘에 삽입된 채로 판매, 유통되기 때문에 의료인이 손쉽게 사용할 수 있는 환부표시기가 구비된 주사기를 제공하는 것이다.Accordingly, the present invention has been made to solve the above problems, the first object of the present invention, because the affected part is sold, circulated while being inserted into the injection needle is provided with a wound indicator that can be easily used by medical personnel To provide a syringe.

As shown in FIG. 2, the syringe body 130 has a cylindrical shape, and an injection needle (or sheath) 120 is fitted at one end thereof, and a core 140 is assembled therein. In addition, the other end of the syringe body 130, the body flange 138 is formed to facilitate the holding of the medical personnel.
주사바늘(120)은 금속체로서 내부에 환부표시기(20), 마개부(110) 및 코어(140)의 일단을 포함한다.The needle 120 is a metal body and includes an affected area indicator 20, a stopper 110, and one end of the core 140 therein.
코어(140)는 주사기 본체(130)와 동축선상에 위치하고, 일단은 주사바늘(120) 내부까지 연장되어 있고, 타단은 주사기 본체(130)의 외부까지 연장되어 코어플랜지(148)를 형성한다. 이러한 코어플랜지(148)는 의료인의 파지를 손쉽게 하고, 코어(140)를 누르기 쉽게 한다.The core 140 is coaxial with the syringe body 130, one end of which extends into the needle 120, and the other end of which extends to the outside of the syringe body 130 to form the core flange 148. The core flange 148 facilitates the gripping of the medical personnel and makes it easy to press the core 140.
도 3은 도 2중 버퍼(135)의 사시도이다. 도 2와 도 3에 도시된 바와 같이, 버퍼(135)는 본체플랜지(138)와 코어플랜지(148) 사이에 끼워져서 간격을 유지하는 간격 유지부재이다. 그리고, 도 3과 같이 환형으로 제작되며, 코어(140)의 끼우기 용이하도록 일측이 반경방향으로 절개홈(137)을 형성한다. 버퍼(135)의 두께는 코어(140)를 앞으로 쭉 밀었을 때, 환부표시기(20)가 주사바늘(120)을 완전히 빠져 나올 수 있는 충분한 길이 정도가 바람직하다.3 is a perspective view of the buffer 135 of FIG. 2. As shown in FIG. 2 and FIG. 3, the buffer 135 is a gap retaining member inserted between the main flange 138 and the core flange 148 to maintain a gap. And, it is manufactured in an annular shape as shown in Figure 3, so that one side of the core 140 to form a cutting groove 137 in the radial direction. The thickness of the buffer 135 is preferably a length sufficient to allow the affected area indicator 20 to completely exit the needle 120 when the core 140 is pushed forward.
본 발명의 실시예를 공장에서 생산할 때, 생산 작업자는 절개홈(137)을 벌려 코어(140)에 끼운다. 이를 위해 버퍼(135)는 절개홈(137)을 벌린 후에도 복원력으로 원래 형상을 유지할 수 있는 탄성력이 필요하다. 이러한 버퍼(135)의 대표적인 재료로는 고무, 합성수지재, 실리콘 등을 들 수 있으나 반드시 이에 국한하는 것은 아니다. When an embodiment of the present invention is produced in a factory, the production worker opens the incision groove 137 and inserts it into the core 140. To this end, the buffer 135 requires an elastic force capable of maintaining its original shape with restoring force even after opening the incision groove 137. Representative materials of the buffer 135 may include rubber, synthetic resin, silicon, and the like, but are not limited thereto.
도 4는 도 2중 A-부분의 확대 단면도이다. 도 4에 도시된 바와 같이, 주사바늘(120)의 내부에는 마개부(110), 환부표시기(20) 및 코어(140)의 일단이 순차적으로 놓이게 된다. 4 is an enlarged cross-sectional view of portion A- in FIG. 2. As shown in FIG. 4, one end of the stopper 110, the affected area indicator 20, and the core 140 are sequentially placed in the needle 120.
마개부(110)는 주사바늘(120)이 피부와 주변 조직이나 장기를 통과할 때 다른 조직이나 물질이 주사기 내부로 들어오는 것을 방지한다. 아울러, 환부표시기(20)가 표시될 때 같이 빠져나와 인체 내부에 잔류하게 된다. 이러한 마개부(110)는 인체내에 잔류하면서 서서히 분해되어 인체에 흡수된다. 이를 위해 마개부(110)의 재질은 인체에 무해하고 신속히 분해될 수 있는 것이 바람직하다. 이러한 물질의 일예로는, 셀룰로오스, 키틴, 키토산, 케라틴, 폴리락트산, 피브로인, 폴리글리콜산, PLGA(Polylactic-Glycolic Acid) 등 기타 생분해성 생체 고분자 물질이 될 수 있으나 이에 반드시 국한되는 것은 아니고, 당업자에게 공지된 것이라면 어떤 것이라도 무방하다.The stopper 110 prevents other tissues or substances from entering the syringe when the needle 120 passes through the skin and surrounding tissues or organs. In addition, when the affected part indicator 20 is displayed, it exits and remains inside the human body. The stopper 110 is slowly disintegrated and absorbed into the human body while remaining in the human body. To this end, the material of the stopper 110 is preferably harmless to the human body and can be quickly disassembled. Examples of such a material may include, but are not limited to, other biodegradable biopolymer materials such as cellulose, chitin, chitosan, keratin, polylactic acid, fibroin, polyglycolic acid, and polylactic-glycolic acid (PLGA), but are not necessarily limited thereto. Anything known to the public is acceptable.
환부표시기(20)는 외경 약 0.5 mm, 내경 약 0.3 mm, 길이 약 5 mm의 코일 스프링 형상의 금속재이고, 백금, 순금사 또는 티타늄 등의 재질을 포함한다. 환부표시기가 금속으로 제작되는 이유는 X-선 촬영, 초음파 검사 또는 방사선 촬영시 선명하게 위치를 나타내도록 하기 위함이고, 코일(스프링) 형태로 제작하는 것은 환부내에 삽입되었을 때 움직이거나 이동하지 못하도록 하기 위함이다. 본 실시예에서는 코일형 환부표시기를 도시하고 설명하였으나 그외에도 막대형 환부표시기 또는 금속와이어를 사용할 수도 있다.The annular indicator 20 is a coil spring-shaped metal material having an outer diameter of about 0.5 mm, an inner diameter of about 0.3 mm, and a length of about 5 mm, and includes a material such as platinum, pure gold yarn or titanium. The reason why the affected area is made of metal is to show the position clearly during X-ray, ultrasonography or radiography, and to produce the coil (spring) in order to prevent it from moving or moving when inserted into the affected area. For sake. In the present embodiment, the coiled annular indicator is shown and described, but in addition, a rod-shaped annular indicator or a metal wire may be used.
도 5는 본 발명의 제 2 실시예에 따른 주사바늘(120)의 부분 확대 단면도이다. 도 5에 도시된 바와 같이, 환부표시기(20)의 표시후, 환부의 생검을 효율적으로 하기 위하여 도 5와 같이 주사바늘(120)의 첨단 구조를 새롭게 구성한다.5 is a partially enlarged cross-sectional view of the needle 120 according to the second embodiment of the present invention. As shown in FIG. 5, after the display of the affected part indicator 20, the tip structure of the injection needle 120 is newly configured as shown in FIG. 5 in order to efficiently biopsy the affected part.
경사기준면(128)은 종래의 주사바늘(120)의 첨단이 갖는 기하학적인 경사면이다. 이러한 경사기준면(120)은 도 5를 기준으로 수평방향에 대해 θ1의 각도(예 : 30도) 만큼 기울어져 있다. 내측경사면(127)은 경사기준면(128)에 대해 주사바늘(120) 내부를 향해 θ2의 각도(예 : 20 ~ 30도)만큼 더 기울어져 있다(최첨단 기준). 내측경사면(127)의 가상의 연장선은 중심점(129)에서 만나도록 형성할 수 있다. 그러나, 중심점(129)의 수렴 조건이 반드시 필요한 것은 아니다. 이로 인해, 내측경사면(127)은 종래 보다 더 날카롭고 뾰족한 형태를 이루게 되고, 내측경사면(127)의 외주 둘레면이 칼날과 같은 작용을 하게 된다. 따라서, 의료인이 주사바늘(120)을 돌렸을 때, 환부에서 더 많은 생검 샘플을 추출할 수 있게 된다.The inclined reference plane 128 is a geometric inclined plane of the tip of the conventional needle 120. The inclined reference plane 120 is inclined by an angle θ 1 (eg, 30 degrees) with respect to the horizontal direction with reference to FIG. 5. The inner inclined surface 127 is further inclined with respect to the inclined reference plane 128 by an angle of θ 2 (for example, 20 to 30 degrees) toward the inside of the needle 120 (a state of the art). The virtual extension line of the inner inclined surface 127 may be formed to meet at the center point 129. However, the convergence condition of the center point 129 is not necessarily required. As a result, the inner inclined surface 127 forms a sharper and pointed shape than before, and the outer circumferential surface of the inner inclined surface 127 acts like a blade. Thus, when the healthcare provider turns the needle 120, it is possible to extract more biopsy samples from the affected area.
도 6는 본 발명의 제 3 실시예에 따른 코어(140)의 부분 확대 사시도와 평면도이다. 도 6에 도시된 바와 같이, 코어(140)의 단부에는 한쌍의 언더커팅부(145)가 형성되어 있다. 언더커팅부(145)는 나사 끝에 형성된 언더커팅과 유사한 형상이어서 일방향으로 회전(예 : 시계방향)할 때는 진행하면서 모재를 파고 들어가고, 반대방향으로 회전(예 : 반시계방향)할 때는 분리되서 나오게 된다. 6 is a partially enlarged perspective view and a plan view of a core 140 according to a third embodiment of the present invention. As shown in FIG. 6, a pair of undercutting portions 145 are formed at the end of the core 140. The undercutting part 145 has a shape similar to the undercutting formed at the end of the screw, so that when it is rotated in one direction (for example, clockwise), the base material is dug in while proceeding, and when it is rotated in the opposite direction (for example, counterclockwise), the undercutting part is separated. do.
실시예의 동작Operation of the embodiment
이하에서는 상기와 같은 구성을 갖는 본 발명의 실시예를 첨부도면을 참조하여 구체적인 동작 방법을 설명하도록 한다. 먼저, 도 2 및 도 4와 같이 준비되어 판매되는 제품을 구입한 뒤, 별도의 개별 포장(미도시)을 제거한 뒤, 버퍼(135)를 분리한다. Hereinafter, with reference to the accompanying drawings an embodiment of the present invention having the configuration as described above will be described a specific operation method. First, after purchasing a product that is prepared and sold as shown in FIG. 2 and FIG. 4, after removing a separate individual package (not shown), the buffer 135 is separated.
그 다음, 환부에 주사바늘(120)을 찌른 후, 코어 플랜지(148)를 밀어서 코어(140)를 전진시킨다. 그러면, 코어(140)의 단부에 의해 마개부(110)와 환부표시기(20)가 밀려서 밖으로 나오게 되어 환부에 위치한다. 이로써 환부 표시 동작은 종료하고, 마개부(110)는 서서히 분해되어 인체 내부로 흡수된다.Then, after inserting the needle 120 into the affected part, the core 140 is pushed forward to advance the core 140. Then, the stopper 110 and the affected part indicator 20 are pushed out by the ends of the core 140 and are located at the affected part. As a result, the wound display operation is terminated, and the stopper 110 is gradually disintegrated and absorbed into the human body.
생검이 필요한 경우, 코어(140)를 더 전진시켜서 주사바늘(120) 밖으로 노출시킨 후, 시계방향으로 조심스럽게 돌린다. 그러면, 언더커팅부(145)가 환부의 일부를 절개하게 되고, 코어(140)를 후퇴시키면 절개된 환부 샘플과 코어(140)가 주사바늘(120) 내부로 함께 들어온다.If a biopsy is needed, the core 140 is further advanced to expose it out of the needle 120 and then carefully turned clockwise. Then, the undercutting part 145 cuts a part of the affected part, and when the core 140 is retracted, the cut affected sample and the core 140 enter together into the needle 120.
추가로 필요한 경우, 주사기 본체(130)와 주사바늘(120)을 조심스럽게 돌려서 내측경사면(127)으로 하여금 환부의 일부를 추출하도록 한다. 코어(140)에 의한 생검 추출과 주사바늘(120)에 의해 추출은 선택적으로, 또는 순차적으로 이루어질 수 있다.In addition, if necessary, the syringe body 130 and the needle 120 is carefully turned to cause the inclined surface 127 to extract a portion of the affected part. Biopsy extraction by the core 140 and extraction by the needle 120 may be selectively or sequentially.
이와 같은 동작후 주사바늘(120)을 빼면 환부표시와 함께 생검 추출을 한번에 할 수 있게 된다.After this operation, the needle 120 is pulled out so that the biopsy can be extracted at the same time with the affected area.
