RC120 Puncture Surgical Navigation and Positioning System

Developed by Ruichu Technology, the RC120 Puncture Surgical Navigation and Positioning System is a CT-guided surgical robot designed to enhance precision and efficiency in percutaneous lung biopsy and interventional oncology procedures.

Product Overview

The RC120 received NMPA Class III medical device registration in February 2024, becoming one of the domestic puncture surgical robots approved for clinical use in China. The system addresses a significant clinical need: lung cancer remains China’s leading cause of cancer-related mortality, with approximately 820,000 new cases and 710,000 deaths reported in 2020 according to WHO data.

Percutaneous CT-guided lung biopsy represents the most common method for diagnosing peripheral lung nodules, but conventional manual procedures typically require 30 minutes and multiple CT scans to confirm needle positioning. The RC120 reduces procedure time to 5-8 minutes while achieving sub-millimeter positioning accuracy.

Key Features

RC120 is a CT-guided puncture robot by Ruichu Technology, featuring marker-free imaging-sensing integration and a standardized three-scan protocol for lung biopsy and interventional oncology.

• CT Imaging and Intelligent Sensing Integration: Proprietary technology that eliminates the need for external markers or registration procedures required by electromagnetic and optical tracking systems
• Sub-millimeter Positioning Accuracy: Mechanical precision enables targeting of small and complex lesions
• Standardized Three-Scan Protocol: First scan for lesion localization, second scan to confirm needle placement, third scan to check for complications
• Universal CT Compatibility: Works with all CT systems of 16 slices or above
• Space-Efficient Design: Integrates directly with CT scanning table without occupying floor space in the CT room

Technical Specifications

RC120 is a CT-guided puncture robot by Ruichu Technology, completing procedures in 5–8 minutes with sub-millimeter positioning accuracy across any CT system of 16 slices or above.

Clinical Applications

The RC120 supports multiple interventional oncology procedures beyond diagnostic biopsy:

Diagnostic Applications:

• Percutaneous lung biopsy for nodule pathology
• Early-stage lung cancer tissue sampling
• Complex anatomical location targeting

Therapeutic Applications:

• Radioactive seed implantation (brachytherapy)
• Ablation therapy (microwave, radiofrequency, cryoablation)
• Targeted drug delivery
• Preoperative localization of small lung nodules

The system’s path planning algorithms account for respiratory motion and help navigate around pulmonary vessels to reduce pneumothorax and bleeding risks.

Regulatory Status

The RC120 received NMPA Class III medical device registration on February 26, 2024, following completion of clinical trials in China.

Clinical Advantages

Compared to conventional manual procedures:

• Procedure time reduced from ~30 minutes to 5-8 minutes
• Sub-millimeter vs. centimeter-level manual positioning
• Standardized workflow reduces operator variability
• Fewer CT scans reduces radiation exposure

Compared to electromagnetic/optical tracking systems:

• No external markers required
• No registration procedures
• Reduced cumulative positioning errors
• Faster setup and workflow

Frequently Asked Questions

What procedures can the RC120 perform?

The RC120 is designed for CT-guided percutaneous procedures including lung biopsy, radioactive seed implantation, ablation therapy guidance, targeted drug delivery, and preoperative nodule localization. All applications involve precise needle positioning under CT imaging guidance.

How does the RC120 differ from other puncture robots?

The RC120 uses integrated CT imaging and intelligent sensing technology that eliminates markers and registration steps required by competing electromagnetic or optical tracking systems. This reduces procedure complexity and improves positioning accuracy.

What CT equipment is compatible with the RC120?

The system is designed to work with all CT scanners of 16 slices or above, integrating directly with the CT scanning table without requiring additional floor space in the procedure room.
