Case Study|Tongji Hospital Achieves Successful Robotic-Assisted Coronary Intervention

Professor Zeng Hesong and his team at Tongji Hospital have successfully completed a coronary intervention using WeMed Medical's independently developed Endovascular Robotic System.

The patient, a 49-year-old man, had experienced intermittent chest pain for six months. Examinations revealed 80% stenosis in the mid-segment of the left anterior descending artery, along with moderate lesions in the right coronary artery. He was also diagnosed with Grade 3 hypertension and had a prior lacunar cerebral infarction.

Given the lesion's location in a highly curved segment, precise intraoperative positioning was critical. After careful discussion with the patient and his family, the team opted for a robotic-assisted procedure. Professor He Xingwei and Dr. Zou Fei assisted in the operation.

Using the robotic system, Professor Zeng advanced the guidewire and deployed a drug-eluting stent with millimeter-level precision. Postoperative imaging confirmed excellent stent placement with no residual stenosis.

Robotic assistance not only improves accuracy-eliminating hand tremor and enhancing stability in complex cases-but also reduces radiation exposure, as physicians can operate remotely from a control console. Advances in signal transmission and control technology are bringing the vision of inter-regional, even international, remote robotic surgeries closer to reality.
