The present invention relates to an automatic fine needle cell aspirator configured to be able to automatically suction extract cells and to accurately discharge the extracted cells by a required amount.

주지하는 바와 같이 세포검사를 하기 위한 수단의 하나로 주사기 본체에 결합된 주사바늘로 신체의 조직을 찔러서 세포를 흡인 추출하여 슬라이드글래스 위에 도말하여 세포검사를 한다.As is known, as a means for performing a cytology, the needle is attached to the body of the syringe by puncturing the tissue of the body and aspirated to extract the cells and smeared on the slide glass to perform a cytology.

종래의 상기와 같은 세포검사를 위한 세포를 흡인 추출하는 일련에 과정을 살펴보면, 우선 주사기 본체에 결합된 주사바늘로 신체의 조직을 찔러 세포를 흡인 추출하는데, 세포를 흡인 추출하기 위하여 본체에 결합된 주사바늘을 이용하여 신체의 조직을 찌르면서 돌리고 빼내는 동작을 수회 반복해서 세포를 흡인 추출하기에 용이한 상태로 만든 후 주사기를 구성하는 플런저를 후진시켜줌으로써 주사기 실린더 내부에 음압을 발생시켜 세포를 흡인 추출하고 있다.Referring to the conventional procedure for aspirating and extracting cells for cytology as described above, first, the cells are sucked and extracted by puncturing the tissue of the body with a needle coupled to the syringe body, which is coupled to the body to suck and extract the cells. Repeatedly rotate and pull out the body tissue using the needle several times to make it easy to suck and extract the cells, and then reverse the plunger constituting the syringe to generate negative pressure inside the syringe cylinder to aspirate the cells. It is extracting.

In this case, the discharge is determined by the senses and habits in the hand. There was a lot of difficulty in aspirating and extracting cells for fine needle cytology, such that the discharge was not constant every time.

따라서, 세포검사에 대한 신뢰도가 떨어질 수밖에 없어 일관된 진단을 하기 어려울 뿐만 아니라 때에 따라서는 환자를 한 번 더 방문하게 하여 반복 검사를 해야 하는 경우가 빈번한 실정이다.Therefore, the reliability of the cell test is inevitably reduced, making it difficult to make a consistent diagnosis. In some cases, the patient is repeatedly visited by visiting the patient once more.

상기한 문제점을 해결하기 위한 본 발명의 자동세침세포흡인기는, 흡인기 본체에 결합된 주사바늘을 이용하여 신체의 조직을 찌르면서 돌리고 빼내는 동작을 수회 반복하는 일련의 과정을 흡인기에 의해서 자동화할 수 있게 하여 시술자의 개인 숙련도와는 무관하게 신뢰성 있게 세포를 흡인 추출할 수 있게 하며,Automatic fine needle cell aspirator of the present invention for solving the above problems, using the needle coupled to the aspirator body to automate a series of processes of repeating the operation of the needle and spin the body of the body several times by the aspirator To reliably aspirate and extract cells regardless of the operator's personal proficiency,

도면의 미설명부호 40은 주사바늘, 41은 주사기, 42는 주사기 실린더, 43은 실린더 손잡이, 44는 플런저, 45는 플런저 손잡이, 46은 허브를 표시한 것이다.In the drawings, reference numeral 40 denotes a needle, 41 a syringe, 42 a syringe cylinder, 43 a cylinder handle, 44 a plunger, 45 a plunger handle, and 46 a hub.

이상과 같이 구성된 본 발명의 자동세침세포흡인기에 관한 작용을 상세하게 설명하면 다음과 같다.Referring to the action of the automatic fine needle cell aspirator of the present invention configured as described above in detail.

본 발명에 의한 자동세침세포흡인기를 사용하여 세포를 흡인 추출하려면, 흡인기 캡(30)을 열고 주사기(41)를 흡인기의 내부에 설치하고 흡인기 캡(30)을 닫는다.To aspirate the cells using the automatic fine cell aspirator according to the present invention, the aspirator cap 30 is opened, the syringe 41 is installed inside the aspirator, and the aspirator cap 30 is closed.

더 구체적으로는 주사바늘(40)이 결합된 주사기 실린더(42)를 흡인기 본체(1)에 형성된 주사기 홀더부(2)에 장착하는데, 이때 실린더 손잡이(43)를 작동구(7)에 형성된 실린더손잡이홈(5)에 결합하고, 또 플런저손잡이(45)를 플런저손잡이홈(11)에 결합한다.More specifically, the syringe cylinder 42 to which the needle 40 is coupled is mounted to the syringe holder portion 2 formed on the aspirator main body 1, wherein the cylinder handle 43 is a cylinder formed on the operating port 7. It is coupled to the handle groove (5), and the plunger handle 45 is coupled to the plunger handle groove (11).

이때 주사기 실린더(42)의 허브(46) 부분은 흡인기 본체로부터 노출되어 있어 세포의 흡인 상태를 볼 수 있다.At this time, the hub 46 portion of the syringe cylinder 42 is exposed from the aspirator body so that the suction state of the cells can be seen.

플런저손잡이홈(11)에 설치된 플런저손잡이 감지센서(12)가 주사기(41)가 장착된 것을 감지하여 신호를 콘트롤러(15)에 보내고, 상기 신호에 의해서 제2모터(14)가 작동하여 내외 스크류기어(16)(17)를 작동시켜줌으로써 플런저(44)를 약간 후진하도록 하여 실린더 내부에 1cc 정도의 공간이 생기게 되는데. 이 준비 과정은 흡인된 검체의 양이 너무 적을 경우에는 밀어내기가 매우 어려우므로, 이렇게 미리 확보한 공간을 이용하여 미량의 검체라도 손쉽게 밀어내도록 하기 위함이다.The plunger handle detecting sensor 12 installed in the plunger handle groove 11 detects that the syringe 41 is mounted and sends a signal to the controller 15. The second motor 14 is operated by the signal to operate the screw. By operating the gears (16) and (17), the plunger (44) is slightly retracted, so that there is about 1cc of space inside the cylinder. This preparation process is very difficult to push out when the amount of sample drawn is too small, so that even a small amount of sample can be easily pushed out using the space secured in advance.

상기와 같이하여 주사기(41)를 흡인기 본체(1)에 장착한 상태에서 신체의 세포를 흡인 추출하는 것이다.As described above, the cells of the body are sucked and extracted while the syringe 41 is mounted on the aspirator main body 1.

상기와 같이 조직의 세포를 흡인 추출하는 과정을 구체적으로 살펴보면, 흡인기에 주사기를 장착하면 플런저가 1cc 정도 후진하여 실린더 내부에 1cc 정도의 공간이 확보된다.Looking at the process of aspirating and extracting the cells of the tissue as described above, when the syringe is mounted on the aspirator, the plunger is reversed by about 1cc to secure a space of about 1cc inside the cylinder.

이어서 조직 내에 주사바늘(40)을 찌른 다음 제1스위치를 누르면 제2모터(14)에 의해 플런저손잡이가 후진하여 실린더 내부에 음압이 걸림과 동시에 제1 모터(8)에 의해 실린더손잡이를 잡고 있는 작동구(7)가 움직이게 되는데 이때 스크류를 따라 전후진과 정역회전을 반복하게 된다. Subsequently, after inserting the needle 40 into the tissue and pressing the first switch, the plunger handle is reversed by the second motor 14 so that a negative pressure is applied to the inside of the cylinder and the cylinder handle is held by the first motor 8. Actuator (7) is to be moved at this time to repeat the forward and backward rotation along the screw.

결국, 주사바늘이 음압이 걸린 상태에서 신체의 조직을 돌면서 찌르고 돌면서 빠지는 작용을 반복하게 되어 조직 내의 세포를 확실하고 신뢰성 있게 흡인 추출할 수 있다.As a result, the needle is repeatedly pierced and rotated while rotating the tissue of the body in the state of negative pressure can be reliably suctioned extraction of cells in the tissue.

제1스위치는 한 번 누르면 다시 누를 때까지 상기 동작을 지속적으로 하게 된다.The first switch is pressed once to continue the operation until it is pressed again.

상기와 같이 세포를 흡인 추출하고 나면, 제1스위치를 놀러 흡인동작을 멈추게 한 뒤 주사기를 신체로부터 빼낸다. 세포검사를 위해서는 흡인 추출된 세포를 필요한 양만큼 배출시켜야 하는데, 이때 제2스위치를 누른다.After aspirating and extracting the cells as described above, the aspirating operation is stopped by playing the first switch, and then the syringe is removed from the body. In order to perform the cytology, the aspirated extracted cells should be discharged as necessary. At this time, press the second switch.

그러면, 제2모터(14)가 작동하여 플런저(44)을 약간 전진시켜 주사기 실린더(42)에 흡인된 세포를 배출시켜주게 되는 것으로 제2스위치를 한 번 누를 때마다 적정 양만큼만 배출되며, 여러 번 눌러 흡인된 검체를 모두 배출 시킬 수 있게 된다. 초기 상태에서 주사기 실린더 약 1cc정도의 여유 공간은 확보해 두었기 때문에 주사기 실린더에 흡인되어 있는 세포의 양이 미량이더라도 남기지 않고 깨끗하게 배출시킬 수 있다.Then, the second motor 14 is operated to advance the plunger 44 slightly to discharge the aspirated cells in the syringe cylinder 42. Each time the second switch is pressed, only the proper amount is discharged. Press once to release all aspirated samples. In the initial state, about 1cc of free space was reserved for the syringe cylinder, so even if a small amount of cells aspirated in the syringe cylinder, it can be discharged cleanly without leaving any trace.
