인공지능(AI) 로봇팔 대장암 검사 VIDEO: Scientists invent a mechanical arm that uses a probe and a MAGNET to check for colorectal cancer in 'less painful' procedure

Would you trust a robot with your colonoscopy? Scientists invent a mechanical arm that uses a probe and a MAGNET to check for colorectal cancer in 'less painful' procedure

In the UK, some 100,000 colonoscopies are performed on patients each year

They see a camera-ended probe passed into the colon to look for abnormalities 

The exam requires highly-skilled doctors and is therefore limited in availability

Researchers developed a smaller probe with and end containing small magnets

The robot arm moves its magnet outside of the body to move the probe within

Artificial intelligence aids the operator and therefore makes it easier to use

인공지능(AI) 로봇팔 대장암 검사    인공지능(AI) 로봇팔은 자석을 이용해 카메라 탐침을 외부로 조종해 대장암을 검사하는 '덜 고통스러운' 대장내시경 검사를 할 수 있다. 대장내시경에서는 길고 얇은 카메라 끝 탐침을 직장과 대장을 통과해 이상을 찾아내고 조직 샘플을 채취한다. 이 검사는 환자에게 불편할 수 있으며 고도의 기술을 갖춘 의사를 수행해야 하므로 시술이 제한된다. 그러나 인공 지능 시스템은 경험이 적은 의사와 간호사들이 대장의 정확한 위치로 조사를 안전하게 안내하는 데 도움을 줄 것이다. 이 시스템을 이용한 환자 실험은 이르면 내년부터 시작될 수 있다. 황기철 콘페이퍼 에디터 Ki Chul Hwang Conpaper editor curator

An AI-powered robotic arm can perform 'less painful' colonoscopies to check for bowel cancer by using a magnet to externally steer a camera probe through the gut.

The system — from a team led from Leeds — could prove to be the first major update in decades to the procedure, which is used some 100,000 times each year in the UK.

In a colonoscopy, a long, thin, camera-ended probe is passed through the rectum and colon to hunt for and remove abnormalities and take tissue samples.

The examination can be uncomfortable for the patient — and requires highly skilled doctors to be performed, limiting the availability of the procedure.

The artificially intelligent system, however, will aid less experienced doctors and nurses in safely guiding the probe to precise locations within the colon.

Patient trials using the system could begin as early as next year.

In a colonoscopy, a long, thin, camera-ended probe is passed through the rectum and colon to hunt for and remove abnormalities and take tissue samples. The examination can be uncomfortable for the patient — and requires highly skilled doctors to be performed, limiting the availability of the procedure. The artificially intelligent system, however, will aid less experienced doctors and nurses in safely guiding the probe to precise locations within the colon. Pictured, the robot offers three modes of assistance, from none (top) through to semi-autonomous navigation (bottom)

Guiding the robotic arm can be done manually — but this is a technique that, like operating an endoscopy conventionally, is difficult to master.

To address this, the researchers developed three different levels of robotic assistance — and evaluated them to see how effective each was in aiding non-specialist staff to carry out a colonoscopy procedure.

The levels of assistance included direct robot control, in which the operator has direct control of the robot via a joystick — with no aid provided.

In the 'intelligent teleoperation' level of assistance, the operator focuses on where they want the capsule to be located in the colon, leaving the robotic system to calculate the movements of the robotic arm necessary to get the capsule there.

Finally, in the 'semi-autonomous navigation' mode, the AI autonomously navigates the capsule through the colon, using visual feedback from the probe's camera — although it can be overridden by the operator as needed.

 

'Colonoscopy gives doctors a window into the world hidden deep inside the human body and it provides a vital role in the screening of diseases such as colorectal cancer,' said paper author and roboticist Pietro Valdastri of Leeds University.

'Colonoscopy gives doctors a window into the world hidden deep inside the human body and it provides a vital role in the screening of diseases such as colorectal cancer,' said paper author and roboticist Pietro Valdastri of Leeds University.

'But the technology has remained relatively unchanged for decades,' he added.

To test the robot, two novice participants were asked to navigate a conventional colonoscope into the colon of two anaesthetised pigs — with a vet in attendance to ensure the animal was not harmed. The participants then repeated the task using the magnet-controlled robotic system, pictured, with each level of assistance. As with the dummy colons, the team found that the operators found it easier to perform the examination when given robotic assistance

'What we have developed is a system that is easier for doctors or nurses to operate and is less painful for patients.'

'It marks an important step in the move to make colonoscopy much more widely available — essential if colorectal cancer is to be identified early.'
