China News Service, July 12 (Chen Jing and Deng Tian) How to further improve the accuracy and success rate of interventional diagnosis of pulmonary nodules is a topic that medical experts are constantly discussing.

  The reporter learned from the Shanghai Chest Hospital on the 12th that under the guidance of Han Baohui, the director of the Department of Respiratory Medicine, the expert Sun Jiayuan team doctors took the lead in successfully carrying out a robotic arm-controlled bronchoscope-guided lung nodule biopsy.

This technology gives full play to the advantages of the robot system, replacing the hand-held operation with a robotic arm, and the whole process is more stable, more flexible, and more precise.

  The doctor only needs to stand behind the intelligent console and control the robotic arm by turning the "trackball", which can quickly and accurately reach the target position, and can easily diagnose some remote complex lesions.

This means that Chinese medical experts have reached a new height in the field of interventional diagnosis of lung diseases.

  Professor Han Baohui told reporters that the technology can locate the shape and position of the catheter in real time.

There is a display screen in front of the doctor. You can see the bronchoscope walking around in the lumen, turning 180 degrees and changing angles, just like a green luminous "snake."

This is clearer and more intuitive than previous 3D images, and the operator seems to be in the patient’s airway, which greatly improves the accuracy, convenience and safety of interventional diagnosis.

  According to reports, in the past, doctors used hand-held bronchoscopes to perform interventional diagnosis. Due to the limited bending angle, it was difficult to pass through some complex airways and distal lesions, requiring very rich experience and stable technology.

Especially in transbronchial lung biopsy, any subtle operation changes may cause the deviation of the target lesion and affect the diagnosis result.

Sun Jiayuan's team then carried out the relevant clinical research on the "robotic arm controlled bronchoscope navigation system".

  The 69-year-old Mr. Huang has multiple nodules in his lungs. The lesions located in the periphery of the lungs are small. He also has a history of bowel cancer surgery. Doctors urgently need to distinguish whether the lung nodules are caused by primary or metastasis.

Routine bronchoscopy may be difficult to reach accurately.

Sun Jiayuan told reporters that through the "robotic arm control bronchoscope navigation system", the team accurately reached the target lesion site.

During the operation, confirmed by fluoroscopy and ultrasound, the doctor successfully completed the biopsy sampling, and rapid on-site cytology revealed adenocarcinoma.

  It is reported that the application of the robotic arm assisted navigation bronchoscopy system has not been reported in China before. The Sun Jiayuan team will continue to advance the research progress, improve the comprehensive level of interventional diagnosis and treatment of lung diseases, so that more patients can benefit as soon as possible.
