TiRobot Sirui Full Orthopedic Surgical Robot
TiRobot Product Family: TiRobot II (Spine & Trauma) | TiRobot Recon (Joint Replacement) | TiRobot Sirui (AI Full Platform)
TiRobot Sirui represents Tinavi’s third-generation full orthopedic surgical robot platform, integrating spine, trauma, and joint replacement capabilities with enhanced AI-powered decision support systems.
Product Overview
Approved by NMPA in 2025, TiRobot Sirui (天玑思睿) consolidates Tinavi’s three surgical application domains—spine, trauma, and joint replacement—into a unified platform with intelligent decision-making features. The system aims to standardize surgical workflows across all major orthopedic subspecialties while introducing automation capabilities beyond the positioning and navigation functions of earlier TiRobot generations.
Tinavi positions TiRobot Sirui as the evolution of its “one machine, multiple applications” philosophy, now enhanced with what the company describes as “decision-support intelligence” that assists surgeons throughout the surgical planning and execution process.
Key Features
TiRobot Sirui is a full orthopedic surgical robot by Tinavi, covering spine, trauma, and joint replacement on one NMPA-approved (2025) platform with 30% faster workflows and 70% less radiation than prior generations.
- Full Orthopedic Coverage: Single platform addresses cervical-to-sacral spine, pelvic/extremity trauma, and knee/hip joint replacement
- Intelligent Decision Support: AI-assisted surgical planning and intraoperative guidance
- 30% Efficiency Improvement: Reported workflow optimization compared to previous generations
- 70% Radiation Reduction: Decreased intraoperative radiation exposure through optimized imaging protocols
- Tianxuan Xingyao Integration: Compatible with Tinavi’s newly approved 3D C-arm imaging system for enhanced intraoperative visualization
Technical Specifications
TiRobot Sirui is a unified AI-assisted orthopedic platform covering full-segment spine, pelvic/extremity trauma, and knee/hip arthroplasty, compatible with 2D fluoroscopy, 3D C-arm, and CT planning.
| Parameter | Specification |
|---|---|
| Surgical Coverage | Spine (full segment), Trauma (pelvis, acetabulum, extremities), Joint (TKA, THA) |
| Intelligence Features | AI-assisted planning, automated trajectory calculation |
| Efficiency Gain | 30% improvement (per manufacturer) |
| Radiation Reduction | 70% lower exposure (per manufacturer) |
| Imaging Compatibility | 2D fluoroscopy, 3D C-arm, CT-based planning |
Clinical Applications
TiRobot Sirui addresses the full spectrum of orthopedic surgical procedures:
Spine Surgery
- Cervical, thoracic, lumbar, and sacral pedicle screw placement
- Spinal deformity correction
- Minimally invasive percutaneous procedures
- Complex revision surgery
Trauma Surgery
- Pelvic ring fracture fixation
- Acetabular fracture reduction
- Femoral neck fracture treatment
- Long bone fracture fixation
Joint Replacement
- Total knee arthroplasty with bone resection guidance
- Total hip arthroplasty with cup and stem positioning
- Soft tissue balancing assessment
- Implant alignment optimization
The platform’s AI capabilities reportedly enable automated recognition of anatomical features and calculation of optimal surgical trajectories, reducing reliance on surgeon experience for complex cases.
Regulatory Status
| Region | Status | Date |
|---|---|---|
| China (NMPA) | Approved | 2025 |
| European Union (CE) | Not Applied | - |
| United States (FDA) | Not Applied | - |
As Tinavi’s newest platform, TiRobot Sirui holds NMPA approval for China only. International regulatory submissions are expected to follow the pathway established by TiRobot II, which obtained CE MDR certification in 2024.
Ecosystem Integration
TiRobot Sirui launches alongside Tinavi’s Tianxuan Xingyao (天璇星耀) three-dimensional C-arm imaging system, also approved in 2025. The combined system provides intraoperative 3D imaging capabilities integrated with robotic navigation, reducing dependence on preoperative CT scans and enabling real-time surgical adaptation.
This integrated approach reflects industry trends toward full surgical suites where imaging, navigation, and robotic assistance function as coordinated systems rather than standalone devices.
Frequently Asked Questions
What is new in TiRobot Sirui compared to TiRobot II?
TiRobot Sirui introduces AI-powered decision support, unified coverage of spine/trauma/joint procedures on a single platform, and improved efficiency (30% faster workflows) and safety (70% radiation reduction) compared to previous generations. TiRobot II remains focused on spine and trauma applications.
Can existing TiRobot II users upgrade to Sirui?
Tinavi has not publicly disclosed upgrade pathways between TiRobot II and TiRobot Sirui. Given the platform evolution and AI feature additions, hospitals may need to evaluate full system procurement rather than software-only upgrades.
What makes TiRobot Sirui a “full orthopedic” platform?
TiRobot Sirui covers all three major orthopedic surgical categories—spine, trauma, and joint replacement—on a single robotic system. Tinavi describes this as globally unique, as most competing systems require separate platforms for joint replacement versus spine/trauma applications.
