Description

내시경 부비동 수술 보호 장치Endoscopic sinus surgery protective device
본 발명은 내시경 부비동 수술 보호 장치에 관한 것으로, 보다 상세하게는 내시경 촬영 영상과 컴퓨터 단층 촬영(computed tomography; CT) 사진을 연동시키는 내시경 부비동 수술 보호 장치에 관한 것이다.The present invention relates to an endoscopic sinus surgery protection device, and more particularly, to an endoscopic sinus surgery protection device for linking the endoscopic image and the computed tomography (CT) photograph.
부비동(paranasal sinus)이란 비강 주위의 빈 공간으로 비강 내로 통해 있으면서 분비물의 배설과 환기에 관여한다. 또한, 비강(nasal cavity)이란 얼굴의 가운데, 코의 등쪽에 있는 코 안의 빈 공간을 말하고, 전방은 외비공에 의해 외계로 통하고 후방은 후비공에 의해 인두와 통하며, 내측은 비중격에 의해 나누어지고 외측은 안구, 뇌실질에 접해져 있다.The paranasal sinus is an empty space around the nasal passages that passes through the nasal passages and is involved in the excretion and ventilation of secretions. In addition, nasal cavity refers to the empty space inside the nose on the dorsal side of the nose, in front of the nasal cavity and into the outer space by the nasal cavity, and the posterior through the pharynx by the nasal cavity. The outer side is in contact with the eye and the brain parenchyma.
부비동의 배출구가 막히면 부비동 내에 농이나 분비물이 고이게 되어 흔히 축농증이라고 불리는 부비동염이 생기게 된다.If the outlet of the sinuses is blocked, sinus or secretions will collect in the sinuses, causing sinusitis, commonly called sinusitis.
이러한 부비동염의 치료로써 부비동 점막 섬모의 정화작용을 유지시키고 해부학적 변형을 피하면서 부비동염 발생에 중요한 부위인 중비도의 부비동 입구 부분을 확장시켜 부비동의 자연구를 통한 배출 및 환기, 병적 점막의 회복을 위한 내시경 부비동 수술이 행해지고 있다. As a treatment for sinusitis, the paranasal sinuses, which are important for sinusitis, are expanded while maintaining the cleansing function of the sinus mucosa and avoiding anatomical deformities, thereby allowing the discharge of the paranasal sinuses, ventilation, and restoration of pathological mucosa.

It takes a lot of time, there was a problem that the accuracy of the operation is poor.

도 2는 본 발명의 일 실시예에 따른 내시경 부비동 수술 보호 장치를 나타내는 도면이다.2 is a view showing the endoscope sinus surgery protective device according to an embodiment of the present invention.
도 2를 참고하면, 본 발명의 일 실시예에 따른 내시경 부비동 수술 보호 장치(11)는 기준 설정부(111), 내시경 위치 측정부(112), 제어부(113)를 포함할 수 있다.2, the endoscope sinus surgery protection device 11 according to an embodiment of the present disclosure may include a reference setting unit 111, an endoscope position measuring unit 112, and a control unit 113.
기준 설정부(111)는 사용자의 입력 신호에 따라 비강에서의 내시경 위치 측정을 위한 시작점을 설정할 수 있다. 내시경 영상과 이에 대응하는 컴퓨터 단층 촬영 사진들을 연동시키기 위해서는 내시경 영상이 나타내는 비강의 위치를 측정하여야 한다. 이때, 비강의 위치 측정의 시작점을 기준 설정부(111)에서 설정함으로써 시작점으로부터 내시경 영상이 나타내는 비강의 위치까지의 거리를 측정할 수 있다. 바람직하게는, 기준 설정부(111)의 시작점은 비강의 전방 부분인 외비공으로 설정할 수 있다.The reference setting unit 111 may set a starting point for measuring the position of the endoscope in the nasal cavity according to the input signal of the user. In order to link the endoscope image and the corresponding computed tomography photographs, the position of the nasal cavity indicated by the endoscope image must be measured. At this time, by setting the starting point of the position measurement of the nasal cavity in the reference setting unit 111, it is possible to measure the distance from the starting point to the position of the nasal cavity indicated by the endoscope image. Preferably, the starting point of the reference setting unit 111 may be set to the nostril, which is a front portion of the nasal cavity.
또한, 기준 설정부(111)는 사용자의 입력 신호에 따라 시작점을 설정하기 때문에 이의 구현은 스위칭 회로를 통해서 이루어질 수 있다. In addition, since the reference setting unit 111 sets the starting point according to the input signal of the user, implementation thereof may be achieved through a switching circuit.
사용자가 내시경을 이동하면서 시작점(예를 들면, 외비공) 부근에서 입력 스위치를 작동시키면 이 시작점을 내시경 위치 측정부(112)에 전송하여 시작점을 기준으로 내시경 영상이 나타내는 비강의 위치까지의 거리를 측정할 수 있다. When the user moves the endoscope and operates the input switch near the starting point (for example, the nostril), the starting point is transmitted to the endoscope position measuring unit 112 to measure the distance to the position of the nasal cavity indicated by the endoscope image based on the starting point. can do.
이러한 기준 설정부(111)의 구현을 위한 스위칭 회로는 다이오드 또는 트랜지스터를 포함할 수 있다.The switching circuit for implementing the reference setting unit 111 may include a diode or a transistor.
내시경 위치 측정부(112)는 기준 설정부(111)에서 설정된 시작점으로부터 촬영된 내시경 영상이 나타내는 비강의 위치까지의 거리를 측정하여 후술하는 연산 제어부(1131)에 전송할 수 있다. The endoscope position measuring unit 112 may measure the distance from the starting point set by the reference setting unit 111 to the position of the nasal cavity indicated by the captured endoscope image and transmit the measured distance to the arithmetic control unit 1131 to be described later.
이러한 내시경 위치 측정부(112)는 다양한 전자 소자 또는 기계 장치를 포함하여 구현될 수 있다. The endoscope position measuring unit 112 may include various electronic devices or mechanical devices.
예를 들면, 내시경에 기계 장치를 통해 미세한 줄을 연결한 후 위치 감지 센서가 줄의 이동 거리를 측정함으로써 시작점으로부터 내시경 영상이 나타내는 비강의 위치까지의 거리를 측정하도록 구현될 수 있다. For example, after connecting a fine line through a mechanical device to the endoscope, the position sensor may be implemented to measure the distance from the starting point to the position of the nasal cavity represented by the endoscope image by measuring the moving distance of the line.
또한, 내시경의 말단부에 위치 감지 센서를 부착하고 이 위치 감지 센서가 감지한 시작점으로부터 내시경 영상이 나타내는 비강의 위치까지의 거리에 해당하는 신호를 유선 또는 무선 통신 시스템을 이용해 내시경과 이격된 곳에 위치한 수신부에서 수신하도록 구현될 수 있다.In addition, the receiver is attached to the distal end of the endoscope, and the receiver located at a distance away from the endoscope using a wired or wireless communication system corresponding to the distance from the starting point detected by the position sensor to the location of the nasal cavity shown by the endoscope image It can be implemented to receive from.
제어부(113)는 내시경 위치 측정부(112)에서 측정된 내시경 위치에 따라 그에 대응하는 컴퓨터 단층 촬영 사진을 컴퓨터 단층 촬영 모니터에 디스플레이 되도록 제어할 수 있다.The controller 113 may control the computer tomography photograph corresponding to the endoscope position measured by the endoscope position measuring unit 112 to be displayed on the CT monitor.
또한, 제어부(113)는 연산 제어부(1131)와 컴퓨터 단층 촬영 제어부(1132)를 포함할 수 있다.In addition, the controller 113 may include an operation controller 1131 and a computed tomography controller 1132.
연산 제어부(1131)는 내시경 위치 측정부(112)에서 측정된 시작점으로부터 촬영된 내시경 영상이 나타내는 비강의 위치까지의 거리를 미리 정해진 복수의 컴퓨터 단층 촬영 사진들 간의 거리 간격에 따라 연산을 수행할 수 있다.The calculation control unit 1131 may perform calculation based on a distance interval between a plurality of predetermined computed tomography photographs from the starting point measured by the endoscope position measuring unit 112 to the position of the nasal cavity indicated by the taken endoscope image. have.
구체적으로 살펴보면, 연산 제어부(1131)는 내시경 위치 측정부(112)에서 측정된 거리를 미리 정해진 복수의 컴퓨터 단층 촬영 사진들 간의 거리 간격으로 나눈 값에 대하여 소수점 첫번째 자리에서 반올림한 정수값을 생성할 수 있다.Specifically, the operation controller 1131 may generate an integer value rounded off at the first decimal place with respect to a value obtained by dividing the distance measured by the endoscope position measuring unit 112 by the distance interval between a plurality of predetermined computed tomography photographs. Can be.
컴퓨터 단층 촬영 제어부(1132)는 연산 제어부(1131)에서 연산된 값에 따라 컴퓨터 단층 촬영 모니터에 해당 컴퓨터 단층 촬영 사진을 디스플레이시키는 제어신호를 생성하여 컴퓨터 단층 촬영 장치에 전송함으로써 내시경 영상에 그에 대응하는 컴퓨터 단층 촬영 사진을 연동시킬 수 있다.The computed tomography control unit 1132 generates a control signal for displaying the computed tomography photograph on the computed tomography monitor according to the value calculated by the operation control unit 1131, and transmits the control signal to the computed tomography apparatus to correspond to the endoscope image. Computed tomography photography can be linked.
예를 들면, 내시경 위치 측정부(112)에서 측정된 거리가 5.5 mm 이고, 미리 정해진 복수의 컴퓨터 단층 촬영 사진들 간의 거리 간격이 3 mm 인 경우, 내시경 위치 측정부(112)에서 측정된 거리인 5.5 mm 를 미리 정해진 복수의 컴퓨터 단층 촬영 사진들 간의 거리 간격인 3 mm 로 나누면 그 값이 1.83이고 이를 소수점 첫번째 자리에서 반올림한 정수값은 2가 된다. 이 정수값을 컴퓨터 단층 촬영 제어부(1132)에 전송하면 컴퓨터 단층 촬영 제어부(1132)는 비강의 전방 부분인 외비공에서부터 후방 부분인 후비공 이후의 부분까지 3 mm 간격으로 촬영된 컴퓨터 단층 촬영 사진들을 순서대로 정렬하여 일련번호 2에 해당하는 2번째 컴퓨터 단층 촬영 사진을 컴퓨터 단층 촬영 모니터에 디스플레이하는 제어신호를 컴퓨터 단층 촬영 장치에 전송할 수 있다. 이러한 과정을 통하여 내시경 영상과 이에 대응하는 컴퓨터 단층 촬영 사진을 연동시킬 수 있다.For example, when the distance measured by the endoscope position measuring unit 112 is 5.5 mm and the distance interval between a plurality of predetermined tomography photographs is 3 mm, the distance measured by the endoscope position measuring unit 112 is Dividing 5.5 mm by 3 mm, which is the distance interval between a plurality of predetermined computed tomography photographs, the value is 1.83 and the integer value rounded to one decimal place is 2. When the integer value is transmitted to the computed tomography control unit 1132, the computed tomography control unit 1132 processes the computed tomography photographs taken at intervals of 3 mm from the anterior part of the nasal cavity to the part after the posterior nasal cavity. The control signal for displaying the second computed tomography photograph corresponding to the serial number 2 on the computed tomography monitor can be transmitted to the computed tomography apparatus. Through this process, the endoscope image and the corresponding computed tomography photograph may be linked.
또한, 제어부(113)는 복수의 컴퓨터 단층 촬영 사진들 간의 거리 간격이 미리 정해진 복수의 컴퓨터 단층 촬영 사진들 간의 거리 간격과 상이한 경우 미리 정해진 복수의 컴퓨터 단층 촬영 사진들 간의 거리 간격을 변경하는 설정 변경부(1133)를 더 포함할 수 있다.In addition, the control unit 113 changes a setting for changing a distance interval between a plurality of predetermined computed tomography photographs when a distance interval between the plurality of computed tomography photographs is different from a predetermined distance interval between the plurality of computed tomography photographs. A part 1133 may be further included.
즉, 보통의 컴퓨터 단층 촬영 사진들 간의 거리 간격은 3 mm 이나 이 간격이 변경되는 경우 설정 변경부(1133)에서 이를 변경함으로써 내시경 영상과 이에 대응하는 컴퓨터 단층 촬영 사진이 서로 대응하도록 연동시킬 수 있다.That is, when the distance between the normal computed tomography photographs is 3 mm or when the interval is changed, the setting change unit 1133 may change the distance so that the endoscope image and the corresponding computed tomography photograph may correspond to each other. .
도 3 내지 6은 내시경 영상과 이에 대응하는 컴퓨터 단층 촬영 사진을 나타낸 도면이다.3 to 6 are views illustrating an endoscope image and a computed tomography photograph corresponding thereto.
도 3 내지 6을 참조하면, 내시경 영상과 이에 대응하는 컴퓨터 단층 촬영 사진들을 연동시킴으로써 시술자가 내시경 부비동 수술을 진행함에 있어 실시간으로 정확한 수술 부위를 확인할 수 있다. 이와 같이 실시간으로 정확한 수술 부위를 확인하는 것은 결국 수술시 발생할 수 있는 의료사고를 미연에 방지하고 시술자에 따른 수술시간의 편차를 감소시키며 전체적인 수술 시간을 단축할 수 있는 장점이 있다.3 to 6, by linking the endoscope image and the computed tomography pictures corresponding thereto, the operator can identify the correct surgical site in real time as the operator performs the endoscopic sinus surgery. As such, identifying the correct surgical site in real time has the advantage of preventing medical accidents that may occur during surgery, reducing the variation of the operation time according to the operator, and reducing the overall operation time.
또한, 내시경 영상과 이에 대응하는 컴퓨터 단층 촬영 사진들을 듀얼 모니터 등을 통해 한 눈에 확인할 수 있게 함으로써 시술자가 보다 용이하게 정확한 수술 부위를 확인하게 할 수 있다.In addition, the endoscope image and the corresponding computed tomography photographs can be checked at a glance through a dual monitor, thereby allowing the operator to easily identify the correct surgical site.
