Q300 Miniature Neurosurgical Robot

The Q300 Mini Robot Navigation System introduces a novel compact form factor to neurosurgical robotics. Weighing approximately 1.4 kg, this system maintains sub-millimeter positioning accuracy while enabling deployment in emergency departments, hospital wards, and settings where larger robotic platforms prove impractical.

Product Overview

Developed by Sinovation to address the accessibility limitations of full-scale neurosurgical robots, the Q300 received NMPA approval through the innovative medical device special review channel in early 2022. The system represents China’s first miniature neurosurgical robot, designed to bridge the gap between high-cost robotic surgery centers and the broader need for precision neurosurgical guidance.

The Q300’s compact design eliminates the substantial capital investment and dedicated operating room requirements of larger systems, enabling hospitals across various tiers to offer robot-assisted neurosurgical procedures. This democratization approach expands patient access to precision stereotactic surgery without compromising on accuracy.

Key Features

At approximately 1.4 kg, the Q300’s compact form enables bedside and emergency-department deployment while maintaining sub-millimeter stereotactic accuracy for brain biopsy and hematoma drainage.

• Ultra-Compact Design: At approximately 1.4 kg, the system enables rapid deployment and repositioning without dedicated installation infrastructure.

• Rapid Laser Surface Scanning: Quick registration using existing CT or MRI images without preoperative marker placement, saving approximately 1 hour of preparation time and reducing overall patient costs.

• Infrared Optical Tracking: The Polaris infrared camera system tracks reflective spheres on patients, surgical tools, and the positioning device, providing outstanding accuracy with resistance to ambient light and electromagnetic interference.

• Dual-Mode Operation: Supports both minimally invasive stereotactic puncture procedures and craniotomy surgical navigation from a single platform.

• Standardized Workflow: Achieves sub-millimeter precision through consistent operating procedures, enabling safe avoidance of key intracranial neurovascular tissues.

• Operating Room Compatible: Integrates directly with operating room lights and microscopes without interference.

Technical Specifications

China’s first miniature neurosurgical robot at ~1.4 kg, Q300 registers in approximately 1 minute using laser surface scanning and supports both stereotactic puncture and craniotomy navigation modes.

Clinical Applications

The Q300 addresses two primary clinical scenarios through its dual-mode design:

Stereotactic Puncture Procedures: For minimally invasive interventions including brain tumor biopsy, hematoma drainage, and electrode placement, the Q300 provides precise spatial positioning while maintaining a compact footprint suitable for emergency or bedside deployment.

Craniotomy Navigation: During lesion removal surgeries for brain tumors and skull base lesions, the system uses real-time infrared tracking to display the spatial relationship between surgical instrument tips and surrounding tissue. This enables maximal safe resection within specified margins, boosting surgeon confidence in high-risk complex procedures.

The system’s portability enables expanded clinical scenarios:

• Emergency department cerebral hemorrhage aspiration
• Bedside procedures in intensive care units
• Smaller hospitals without dedicated robotic surgery suites
• Multi-site deployment within large hospital systems

Frequently Asked Questions

How does Q300 compare to the Sinobot X1?

The Q300 offers a compact, cost-effective alternative weighing only 1.4 kg compared to the full-scale Sinobot X1. While the Sinobot X1 uses 3D structured light registration and has FDA approval, the Q300 employs laser surface scanning and focuses on accessibility for broader hospital adoption. Both achieve sub-millimeter accuracy.

Can Q300 be used in emergency settings?

Yes. The Q300’s compact design and rapid registration (approximately 1 minute) enable deployment in emergency departments for procedures like cerebral hemorrhage aspiration, without requiring transfer to dedicated operating rooms.

What surgeries can Q300 perform?

The Q300 supports stereotactic puncture procedures (brain tumor biopsy, hematoma drainage, electrode placement) and craniotomy surgical navigation for tumor and skull base lesion removal. The dual-mode design covers both minimally invasive and open neurosurgical approaches.

Does Q300 require preoperative markers?

No. The Q300 uses rapid laser surface scanning registration technology, eliminating the need for preoperative marker placement and additional localization imaging, saving approximately 1 hour of preparation time.
