SR01-200 Laparoscopic Surgical Robot

The SR01-200 is a four-arm laparoscopic surgical robot developed by Wiseking Surgical, a subsidiary of Kangji Medical (09997.HK). Receiving NMPA approval in April 2025, it became Zhejiang Province’s first domestically developed laparoscopic surgical robot to achieve commercial registration, marking a significant milestone for China’s surgical robotics industry.

Product Overview

Designed for multi-specialty complex minimally invasive surgeries, the SR01-200 provides surgeons with enhanced visualization, precision control, and reduced physical fatigue during extended procedures. The system targets the domestic replacement market, offering Chinese hospitals an alternative to imported platforms at a potentially more accessible price point.

The development team prioritized reliability and clinical practicality. General Manager Pan Bo emphasized during the product launch that providing a “safe and reliable surgical robot system” was the primary development objective, rather than pursuing features for their own sake.

Key Features

SR01-200’s 23%-smaller endoscope and 0.5x–16x continuous electronic zoom give surgeons detailed views and faster channel switching without physically repositioning during complex procedures.

Four-Arm Configuration: The system deploys four robotic arms—one for the endoscope and three for surgical instruments. This configuration enables complex multi-quadrant procedures while minimizing the need for assistant port manipulation.

4K Ultra-High-Definition Visualization: Dual displays operating at 3840×2160 resolution provide four times the pixel density of standard full HD systems. The immersive 3D visualization helps surgeons identify fine anatomical structures with improved clarity.

Continuous Electronic Zoom: Variable magnification from 0.5x to 16x allows surgeons to transition smoothly between wide-field overview and detailed close-up views without physically repositioning the endoscope.

Compact Endoscope Design: The endoscope diameter has been reduced by 23% compared to competing products, allowing faster switching between instrument and observation channels during procedures.

Tremor Filtration: Proprietary algorithms filter physiological hand tremors from the master controller, enabling steadier instrument movements particularly valuable during delicate tasks like suturing and dissection.

Master-Slave Mapping: Real-time mapping between the surgeon console and robotic arms ensures instrument tips precisely replicate intended movements without perceptible delay.

Technical Specifications

Approved by NMPA in April 2025 as Zhejiang’s first domestic laparoscopic robot, SR01-200 provides four arms, dual 4K screens at 3840×2160, and 0.5x–16x zoom for urology, gynecology, and general surgery.

Clinical Applications

The SR01-200 completed multi-center registration clinical trials at two major Zhejiang University-affiliated hospitals:

• Sir Run Run Shaw Hospital: Urology, general surgery, and gynecology procedures
• Second Affiliated Hospital: Multi-specialty surgical validation

Approved clinical indications cover three primary specialties:

Urology: Procedures including prostatectomy, nephrectomy, and bladder surgery where the enhanced visualization and tremor filtration support nerve-sparing techniques.

Gynecology: Hysterectomy and other pelvic procedures benefit from the articulated instruments’ ability to navigate confined surgical spaces.

General Surgery: Applications including cholecystectomy, gastrectomy, and colorectal procedures where the multi-arm configuration reduces reliance on surgical assistants.

Regulatory Status

The system represents Zhejiang Province’s first locally developed laparoscopic surgical robot to receive NMPA registration. Mass production commenced in August 2025.

Frequently Asked Questions

What surgeries can the SR01-200 perform?

The SR01-200 is approved for laparoscopic procedures in urology (prostatectomy, nephrectomy), gynecology (hysterectomy), and general surgery (cholecystectomy, colorectal surgery). The four-arm configuration supports complex multi-step procedures requiring precise instrument coordination.

How does the SR01-200’s visualization system work?

The system employs dual 4K displays (3840×2160 resolution) providing stereoscopic 3D visualization. Continuous electronic zoom from 0.5x to 16x magnification lets surgeons adjust views without repositioning the endoscope. The compact endoscope design (23% smaller than competitors) enables instrument channel switching.

Is the SR01-200 available outside China?

Currently, the SR01-200 has only received NMPA approval in China. The manufacturer has not announced plans for CE marking (Europe) or FDA clearance (United States). International availability would require additional regulatory submissions.

What is the price of the SR01-200 system?

Pricing has not been publicly disclosed. However, Wiseking positions the system as a cost-effective domestic alternative to imported platforms, targeting not only top-tier hospitals but also prefecture-level facilities where premium imports may be cost-prohibitive.
