uIntervC550 Percutaneous Intervention Robot

The uIntervC550 represents UI Surgical’s entry into the percutaneous intervention robot market, offering CT-guided precision for biopsy and ablation procedures. The system received NMPA Class III medical device registration in 2025 and has been deployed at leading Chinese academic medical centers.

Product Overview

Developed by UI Surgical (联影智融), the uIntervC550 addresses the technical challenges of CT-guided interventional procedures by combining robotic precision with real-time imaging integration. The system enables what the company describes as “real-time visualization” surgical procedures, where clinicians can continuously monitor needle positioning relative to target lesions and critical structures.

The robot is designed to work in coordination with CT imaging systems, leveraging UI Surgical’s parent company United Imaging’s expertise in diagnostic imaging to create an integrated intervention platform.

Key Features

uIntervC550’s sub-millimeter articulated arm delivers 360-degree CT-guided needle positioning with respiratory motion compensation, reducing repeated imaging cycles during intervention.

• Precision Robotic Arm: Sub-millimeter positioning capability with 360-degree movement range, controlled by generative AI technology that interprets surgeon intentions for precise instrument manipulation

• Real-Time CT Integration: Enables continuous visualization of needle trajectory and target during procedures, reducing the need for repeated imaging verification scans

• Multimodal Image Fusion: Combines preoperative CT, MRI, and other imaging to create thorough procedural plans with clear target delineation and risk structure identification

• Intelligent Path Planning: AI-assisted algorithms analyze imaging data to suggest optimal trajectories while providing risk warnings for critical structure proximity

• Respiratory Motion Compensation: Adapts to patient respiratory movement during procedures involving thoracic or upper abdominal targets

Technical Specifications

Deployed at Tongji Hospital and Peking Union Medical College Hospital, uIntervC550 achieves sub-millimeter percutaneous positioning under CT guidance with AI-powered motion control.

Clinical Applications

The uIntervC550 supports various CT-guided interventional procedures:

Percutaneous Biopsy: Enables precise tissue sampling from lesions throughout the body, particularly valuable for lung nodules, liver masses, and other targets requiring accurate needle placement.

Tumor Ablation: Supports positioning of ablation probes for radiofrequency ablation (RFA), microwave ablation (MWA), and cryoablation procedures, where electrode placement accuracy directly impacts treatment efficacy.

Drainage Procedures: Facilitates catheter placement for abscess drainage and fluid collection management.

Pain Management: Supports interventional pain procedures requiring precise needle positioning near neural structures.

Hospital Deployments

The uIntervC550 has been clinically deployed at major Chinese academic medical centers including:

• Tongji Hospital, Wuhan
• Tianjin Cancer Hospital
• Peking Union Medical College Hospital (Beijing Xiehe)
• Ruijin Hospital, Shanghai

These deployments at leading institutions demonstrate the system’s capability to meet the demanding requirements of high-volume interventional radiology programs.

Regulatory Status

The uIntervC550 received NMPA Class III medical device registration in 2025.

Frequently Asked Questions

What procedures can the uIntervC550 perform?

The uIntervC550 is designed for CT-guided percutaneous procedures including biopsies, tumor ablations (RF, microwave, cryo), drainage catheter placements, and interventional pain management procedures. The robotic system provides precise needle positioning under CT guidance.

How does the uIntervC550 differ from manual CT-guided procedures?

The robotic system offers sub-millimeter positioning accuracy and stable needle trajectory maintenance, reducing the number of repositioning attempts typically required in manual procedures. The generative AI motion control interprets surgeon intentions for precise instrument manipulation, while real-time CT integration provides continuous visualization without repeated imaging cycles.

Which CT systems are compatible with the uIntervC550?

The uIntervC550 is designed to integrate with CT imaging systems. Given UI Surgical’s relationship with United Imaging Healthcare, the system is optimized for use with United Imaging CT scanners, though compatibility with other manufacturers’ equipment should be confirmed with UI Surgical directly.
