KangDuo SR1000 Laparoscopic Surgical Robot
KangDuo Product Family: SR1000 (Entry) | SR1500 (Mid) | SR2000 (Flagship) | SS2000 (Training)
KangDuo SR1000 represents Sagebot’s first commercially available laparoscopic surgical robot, holding the distinction of being the first such system in China’s urology field to enter the NMPA’s Special Approval Procedure for Innovative Medical Devices. The three-arm system has progressively expanded its approved indications across four surgical specialties since its initial approval in June 2022.
Product Overview
The KangDuo SR1000 is a master-slave robotic surgical system designed to assist surgeons in performing minimally invasive procedures across urology, gynecology, general surgery, and thoracic surgery. As Sagebot’s foundational commercial product, it embodies the company’s philosophy of independent R&D without imitation, featuring wholly indigenous intellectual property across its core subsystems.
The system distinguishes itself through an open surgeon console architecture—the first domestically developed robot with this design to receive NMPA approval. This configuration allows surgeons to maintain direct visual contact with the operating room team and patient while operating the robotic system.
Key Features
Open Console Design: Unlike enclosed console designs common in other surgical robots, the KangDuo SR1000’s open architecture enables the operating surgeon to remain connected with the broader surgical team, facilitating communication and situational awareness.
Multi-Display Visualization: The surgeon console provides multiple screens—one displaying 3D endoscopic views while others show 4K HD fluorescent navigation imagery and pre-operative 3D reconstruction images.
Endoscope Compatibility: The system is compatible with 4K fluorescent endoscopes and can interface with most 3D endoscopes available in the market, eliminating the need for proprietary optics.
5G Remote Surgery Capability: Building on Sagebot’s pioneering 5G remote surgery achievements, the SR1000 platform supports telesurgery applications for training and potentially clinical procedures.
Intuitive Master-Slave Control: The system replicates surgeon hand movements at the surgical instrument tips, enabling precise execution of complex surgical maneuvers.
Technical Specifications
For urology, gynecology, general surgery, and thoracic surgery, Sagebot’s KangDuo SR1000 provides three-arm laparoscopic robotic assistance with 3D HD visualization and 5G remote surgery capability through an open-design surgeon console.
| Parameter | Specification |
|---|---|

System Components
The KangDuo SR1000 system comprises:
- Surgeon Console: Open-design workstation with 3D viewing system and master controllers
- Patient Cart: Mobile unit housing robotic arms for instrument and camera manipulation
- Vision Cart: Image processing unit integrating cold light source and video management
- Endoscopic System: 3D HD electronic endoscope with 0° and 30° viewing angles
- Surgical Instruments: Wristed instruments with multiple degrees of freedom
Clinical Applications
The KangDuo SR1000 has received NMPA approval for procedures across four surgical specialties:
Urology (June 2022, expanded February 2023): Upper urinary tract procedures including radical prostatectomy, partial nephrectomy, and pyeloplasty; lower urinary tract procedures
Gynecology (January 2024): Gynecological laparoscopic procedures
General Surgery (February 2024): Lower gastrointestinal tract procedures
Thoracic Surgery (June 2024): Pulmonary procedures via thoracoscopic approach
Clinical Evidence
Registration clinical trials compared the KangDuo SR1000 against the da Vinci surgical system for partial nephrectomy in 99 evaluable patients (49 KangDuo, 50 da Vinci):
| Metric | KangDuo SR1000 | da Vinci |
|---|---|---|
| Surgical Success Rate | 100% | 100% |
| Intraoperative Blood Loss | 57.63±125.91 mL | Comparable |
| Robot Arm Operation Time | 69.55±30.87 min | Comparable |
No statistically significant differences were observed in primary efficacy, secondary efficacy, or safety endpoints between the two systems.
The KangDuo SR1000 achieved a notable milestone as the first domestically developed laparoscopic surgical robot to complete 100 procedures at a single hospital, accomplished at Peking University First Hospital’s urology department.

Frequently Asked Questions
What surgeries can KangDuo SR1000 perform?
The KangDuo SR1000 is approved for laparoscopic procedures in urology (radical prostatectomy, partial nephrectomy, pyeloplasty, bladder procedures), gynecology, general surgery lower GI operations, and thoracic surgery lung procedures.
How much does KangDuo SR1000 cost?
Published tender records indicate winning bid prices of approximately RMB 5.38-5.50 million (roughly $750,000-770,000 USD), positioning it at approximately one-third the cost of comparable imported systems.
How does KangDuo SR1000 compare to da Vinci?
Clinical trial data for partial nephrectomy showed equivalent surgical success rates (100% for both systems) and no statistically significant differences in safety or efficacy endpoints. Key differences include the open console design (vs. enclosed for da Vinci) and significantly lower acquisition cost.
