Jingmai Puncture Surgery Navigation System

Developed by Jingmai Medical, this intelligent puncture surgery navigation system combines C-arm and CT imaging fusion with virtual reality visualization to guide percutaneous interventions for thoracic and abdominal tumors. The system received NMPA Class III certification in August 2021 alongside its companion disposable electromagnetic positioning needle.

Product Overview

The Jingmai Puncture Surgery Navigation System addresses a critical challenge in interventional oncology: achieving consistent sub-centimeter accuracy during percutaneous tumor access. By integrating deep learning-based image processing with real-time electromagnetic tracking, the system provides surgeons with continuous positional feedback throughout biopsy and ablation procedures.

Unlike traditional freehand CT-guided techniques that require multiple verification scans, this navigation approach enables direct path planning and execution with minimal radiation exposure to both patients and operators.

Key Features

The Jingmai Puncture Surgery Navigation System is a CT/C-arm guided navigation platform by Jingmai Medical, featuring multi-modal image fusion and deep learning respiratory motion compensation for percutaneous tumor procedures.

• Multi-modal Image Fusion: Combines C-arm fluoroscopy and CT volumetric data into unified 3D visualization
• Virtual Reality Interface: Provides immersive surgical planning environment for intuitive path selection
• Respiratory Motion Compensation: Deep learning algorithms track and correct for breathing movement in real-time
• Automated Registration: Pre-operative setup completed through fully automatic alignment processes
• Electromagnetic Tracking: Companion positioning needle provides continuous instrument localization
• Risk Zone Visualization: Highlights critical structures including vessels and airways during planning

Technical Specifications

This NMPA Class III-approved system by Jingmai Medical delivers sub-3mm electromagnetic tracking accuracy with fully automated deep learning registration for CT- and C-arm-guided thoracic and abdominal interventions.

Clinical Applications

The navigation platform supports the complete spectrum of percutaneous thoracic and abdominal interventions:

Diagnostic Procedures

• Fine needle aspiration biopsy
• Core needle biopsy
• Lesion localization for surgical resection

Therapeutic Interventions

• Radiofrequency ablation (RFA)
• Microwave ablation (MWA)
• Cryoablation
• Irreversible electroporation (NanoKnife)
• Brachytherapy seed implantation
• Intratumoral chemotherapy delivery

The sub-3mm accuracy specification meets the clinical requirements for sampling early-stage lung nodules (≤8mm) as recommended in China’s 2021 lung cancer screening guidelines.

Companion Consumable

The Disposable Electromagnetic Positioning Needle, approved simultaneously with the navigation system, serves as the tracking instrument during procedures. As China’s first intelligent navigation puncture needle, it provides:

• Real-time tip position feedback to the navigation console
• Compatibility with standard biopsy and ablation workflows
• Single-use sterile design eliminating cross-contamination risk

Regulatory Status

Clinical Evidence

Validation across multiple tier-three hospitals in China demonstrated:

• Over 200 clinical procedures completed
• Consistent positioning accuracy below 3mm
• Successful application across lung, liver, kidney, and other solid organ lesions
• Simplified workflow enabling adoption at primary healthcare facilities

Frequently Asked Questions

What imaging modalities does the Jingmai navigation system support?

The system integrates both C-arm fluoroscopy and CT imaging data, fusing them into a unified 3D visualization for surgical planning and real-time guidance.

How does the system compensate for patient breathing?

Deep learning algorithms analyze respiratory patterns and apply real-time drift correction, maintaining targeting accuracy even during normal breathing without requiring extended breath holds.

Is the electromagnetic positioning needle reusable?

No, the positioning needle is a single-use disposable device designed for sterility and optimal tracking performance during each procedure.

What accuracy has been demonstrated in clinical use?

Clinical validation across over 200 cases showed consistent positioning accuracy within 3mm, meeting requirements for early lung cancer nodule biopsy.
