Early detection and treatment of lung cancer is very important, and traditional percutaneous lung biopsy often requires multiple CT scans, and the puncture time may be as long as one to two hours. Recently, the team of Li Jing, chief physician of the Respiratory and Critical Care Department of Guangdong Provincial People's Hospital, used a newly developed robotic lung puncture assistance system to complete percutaneous lung puncture biopsy for patients within 10 minutes with only 1 needle. This method also greatly reduces the number of CT scans and reduces radiation exposure. According to reports, this is the first application of the system in South China.
New technology! South China's first robot-assisted puncture biopsy
Not long ago, Ms. Gu, 58, went to Guangdong Provincial People's Hospital for treatment because of "left lung occupation." Due to the need for percutaneous lung biopsy to make a definitive diagnosis, the team of the respiratory and critical care Department of the hospital adopted robot-assisted guided lung biopsy after a comprehensive assessment of the patient, informing the patient of the relevant risks, and obtaining the patient's informed consent. During the operation, only one needle was used to complete the accurate puncture of the lung nodules, and the whole puncture time was only 10 minutes. No postoperative complications such as pneumothorax and hemoptysis occurred in the patient.
Professor Li Jing introduced that the traditional percutaneous lung biopsy highly relies on the clinical experience of the surgeon, testing the surgeon's familiarity with the chest anatomical structure and three-dimensional reconstruction imagination, and often requires multiple CT scans to adjust the positioning Angle and depth of the puncture. For small lesions, the location is difficult to reach, the patient's breathing coordination is poor, and the surgeon is inexperienced, sometimes the puncture is as long as one or two hours.
Now, with the application of the new technology robot assisted system for lung puncture, doctors only need to collect data from one CT scan before surgery, and confirm the location of the puncture needle with one CT scan after arriving at the lesion, and then complete the puncture positioning. "It significantly shortens operation time, reduces the number of CT scans, reduces radiation exposure, reduces the difficulty of percutaneous lung puncture, and helps promote the popularization of percutaneous lung tissue biopsy and ablation surgery to the grassroots unit." Li Jing introduces the features of the new technology.
Respiratory displacement can be tracked to reduce radiation exposure
"This new robot-assisted technology is especially suitable for difficult puncture where the lesion size is small and the location of the lesion is easily affected by respiratory movement, which brings new options and new hopes for the diagnosis and treatment of patients with lung nodules." Li Jing introduced that the robot assistance system integrates a number of advanced technologies such as optical navigation, artificial intelligence, and robotic arm assisted positioning. With the patient's breathing movement, the puncture needle can be guided along the preset puncture route and target point through the image simulation.
In the process of puncture, three-dimensional spatial position visualization of tissue structure and puncture path can be realized, effectively avoiding bones, blood vessels and important organs on the puncture path, and reducing the difficulty of surgical planning. The optical navigation can also track the amplitude of respiratory displacement in real time and reduce the deviation of respiratory displacement.
It is reported that the system is a new type of intelligent puncture intervention equipment developed by Guangdong Provincial People's Hospital, which is committed to assisting in the completion of puncture biopsy, ablation and other interventional operations quickly, accurately and stably. At present, the Department of Respiratory and Critical Care Medicine of Guangdong Provincial People's Hospital is carrying out clinical research on robot-assisted percutaneous lung puncture technology. If there are patients who need to participate in clinical research trials, they can contact the relevant departments of the hospital for consultation.
