The neurointerventional robot PANVIS STAR, jointly developed by Liu Jianmin's team at Shanghai Changhai Hospital and Guo Shuxiang's team at Southern University of Science and Technology, with Shenzhen Aibo Hechuang participating in industrialization, completed full-process validation of five major categories of procedures in a pig model: cerebral angiography and access establishment, aneurysm coil embolization, flow diverter placement, vertebral artery stenting, and carotid artery stenting. All procedures were successful, with no device-related complications or vascular injury. The study was published in the Journal of Robotic Surgery. The entire process, from guidewire and catheter superselection to release of the implanted device, was performed by the robot; manual operations were limited to catheter sheath insertion, device replacement, and loading in a radiation-free environment. The study was a preliminary experiment using 3 pig models, had no manual control group, had a limited sample size, and did not construct a stenosis model in order to validate technical feasibility; the research team stated that larger-scale trials with clinical and follow-up endpoints are still needed for validation.
