[Experimental study of angiography using vascular interventional robot-2(VIR-2)]

Area of Science:

• Medical robotics
• Vascular interventions
• Surgical technology

Context:

• Vascular interventional procedures require high precision and can pose risks to operators.
• Existing robotic systems may have limitations in control and feedback.
• Advancements in robotic technology are crucial for improving minimally invasive procedures.

Purpose:

• To evaluate the feasibility and safety of the novel vascular interventional robot type-2 (VIR-2).
• To assess the system's performance in remote catheter control and angiography.
• To determine the accuracy, efficiency, and safety of VIR-2 in pre-clinical settings.

Summary:

• The VIR-2 system, featuring master-slave control, image navigation, and real-time force feedback, was tested in vitro and in canine cerebral angiography.
• Catheter positioning error was less than 1 mm, with a 100% success rate in animal procedures.
• The system enabled remote operation, improved efficiency, and eliminated staff exposure to DSA radiation, with force feedback enhancing operational security.

Impact:

• VIR-2 proves to be a safe and effective tool for remote vascular interventions and angiography.
• The system's master-slave functionality aligns with traditional procedural characteristics.
• Enhanced 3D imaging and force feedback contribute to smoother, safer operations, paving the way for advanced robotic surgery.
