Dasheng Magnetically Controlled Capsule Endoscopy System
Developed over ten years by Jifu Medical, the Dasheng Magnetically Controlled Capsule Endoscopy System offers physicians precise control over a swallowable camera capsule, enabling full stomach visualization without traditional intubation or sedation requirements.
Product Overview
The Dasheng system received both NMPA Class III medical device registration and CE certification in December 2019, marking Jifu Medical’s entry into the commercial capsule gastroscopy market. The platform distinguishes itself through a standing-type magnetic control design that eliminates robotic arms while maintaining precise capsule manipulation.
Patients swallow a pill-sized capsule containing a miniature high-definition camera. Physicians then guide the capsule’s position and orientation using external magnetic fields, capturing detailed imagery of the gastric mucosa. The examination proceeds without sedation, making it suitable for patients who cannot tolerate traditional gastroscopy.
Key Features
For gastric cancer screening without intubation or sedation, Jifu Medical’s Dasheng uses a standing-type magnetic platform and a triple-lens 136° capsule to guide full stomach examination in roughly 15–20 minutes.
Standing-Type Magnetic Control: The guidance system employs a standing platform design without mechanical arms, containing integrated wireless receivers that track and control capsule position through magnetic field manipulation.
Three-Lens Optical System: The capsule houses a triple-lens configuration achieving 136° field of view, capturing detailed images of gastric tissue across varying distances.
Extended Battery Life: Neutral water density construction and power-efficient design provide prolonged examination time with built-in retention monitoring to ensure complete passage.
AI-Powered Reading Station: The accompanying intelligent workstation processes thousands of images per examination, filtering duplicates and generating automated reports in approximately 15 minutes.
Technical Specifications
For sedation-free gastric screening, the Dasheng capsule combines a 136° triple-lens system capturing at 4 fps with 0–50mm depth of field, transmitting wirelessly to an AI workstation that generates reports in roughly 15 minutes.

System Components
The Dasheng platform comprises three integrated elements:
- Capsule Endoscope: Swallowable device with embedded HD camera, LED illumination, wireless transmitter, and internal power source
- Magnetic Guidance Robot: Standing-type control platform generating precisely modulated magnetic fields for capsule manipulation
- Imaging Workstation: Computer system receiving real-time video feed, processing images, and supporting AI-assisted diagnosis
Clinical Applications
The system supports gastric examination for various clinical scenarios:
- Screening Programs: Population-level gastric cancer screening where traditional endoscopy compliance remains low
- Intolerant Patients: Individuals who cannot undergo conventional gastroscopy due to anxiety, gag reflex, or medical contraindications
- Follow-up Examinations: Monitoring patients with known gastric conditions requiring periodic visualization
- Initial Assessment: First-line evaluation of upper abdominal complaints before more invasive procedures
Contraindications include acute enteritis, suspected gastrointestinal obstruction or perforation, severe throat disease, implanted electronic devices, and pregnancy.

Competitive Positioning
In China’s magnetic capsule endoscopy market, Dasheng competes primarily with Ankon Technologies’ NaviCam system and Jinshan Science & Technology’s OMOM platform. The standing-type design differentiates Jifu’s approach from competitors using robotic arm guidance systems.
The technology addresses specific market needs:
- Simplifies equipment installation and maintenance compared to robotic arm systems
- Requires less specialized training for operators
- Offers a compact footprint suitable for outpatient screening centers
Frequently Asked Questions
How does Dasheng compare to traditional gastroscopy?
Dasheng provides a comfortable, sedation-free alternative to conventional gastroscopy. While traditional endoscopy offers therapeutic capabilities and direct tissue sampling, Dasheng excels in screening applications where patient comfort drives examination compliance.
What is the examination procedure like?
Patients fast before the procedure, then swallow the capsule with water. The examination takes approximately 15-20 minutes as physicians guide the capsule through the stomach. The capsule passes naturally through the digestive tract over subsequent hours.
Can any physician operate the Dasheng system?
General endoscopy physicians can operate the system after professional training on the magnetic control interface. This accessibility helps address physician shortages in endoscopy departments.
What happens to the capsule after the examination?
The disposable capsule passes through the digestive system naturally and is eliminated within 24-72 hours. The system includes retention monitoring to confirm capsule passage.
