Overview and Application Guidelines of Disposable Biliary Endoscopy Technology

Disposable cholangioscopy, also known as disposable electronic cholangiopancreatography or disposable cholangiopancreatography catheter visualization system, is an electronic endoscope that is ultra-fine, flexible, and designed specifically for single use. It is mainly used in endoscopic retrograde cholangiopancreatography (ERCP) surgery, which can directly enter the bile ducts and pancreatic ducts of the human body, providing doctors with high-definition direct vision images for the diagnosis and treatment of biliary and pancreatic system diseases. Its core value lies in completely eliminating the risk of cross infection through a single use and simplifying clinical procedures.

1. Analysis of core advantages

Compared with traditional reusable cholangioscopes, disposable cholangioscopes have the following significant advantages:

1.1 Ultimate Infection Control

Disposable disposal fundamentally solves the problem of cross infection between patients caused by incomplete cleaning and disinfection, greatly improving the safety of surgery.

1.2 Stable and excellent performance

Each surgery uses brand new and undamaged mirrors, ensuring optimal image clarity, brightness, and flexibility in mirror control, guaranteeing diagnostic accuracy and surgical success rate.

1.3 Comprehensive Cost Optimization

Although there is a cost for consumables in a single operation, it eliminates the expensive initial equipment purchase cost, specialized cleaning and disinfection equipment cost, expensive manual cleaning cost, and periodic maintenance cost. From the perspective of overall hospital operation, it may be more economical.

1.4 Improving surgical efficiency

Ready to use, without the need for complex and time-consuming preoperative leak detection, cleaning, disinfection, and postoperative treatment processes, significantly reducing surgical table connection time and improving the efficiency and turnover rate of endoscopic centers.

1.5 Reduce radiation exposure between doctors and patients

In some surgical procedures, clear visual imaging can reduce reliance on traditional X-ray contrast, thereby reducing the radiation dose received by doctors and patients during the operation.

2. Main clinical application scenarios

Disposable cholangioscopy is mainly used for the diagnosis and treatment of the following biliary and pancreatic duct diseases:

*Difficult bile duct stones: Used to treat complex situations such as giant stones and intrahepatic bile duct stones, laser lithotripsy or electrohydraulic lithotripsy can be performed under direct visualization.

*Bile duct stenosis or space occupying lesions: Direct visual observation and precise biopsy of unexplained bile duct stenosis or suspected tumor lesions can significantly improve the diagnostic positivity rate.

*ERCP intraoperative exploration: replacing some traditional imaging techniques, directly entering the biliary tract for exploration to clarify the nature of the lesion.

*Postoperative evaluation: used to assess whether the stones have been removed completely and whether the stent position is appropriate.

3. Key elements of procurement and evaluation

When choosing disposable cholangioscopy products, it is recommended that medical institutions focus on the following aspects:

3.1 Regulations and Compliance (Primary Condition)

It is necessary to confirm that the product has obtained the necessary medical device registration certificate in the market, such as the registration certificate from the National Medical Products Administration (NMPA) of China (registration number can be queried, such as: National Medical Device Injection 20172061143), FDA approval in the United States, or CE certification in the European Union.

3.2 Optical Imaging Performance

Focus on the quality, resolution, field of view, depth of field, and color reproduction of image sensors. Excellent imaging quality is the foundation for accurate diagnosis and efficient treatment.

3.3 Operability and Handling Performance

Evaluate the flexibility, pushing ability, head bending angle (recommended to choose bidirectional or four-way bending), as well as the response speed and accuracy of manipulation of the mirror body, which directly affect the smooth progress of the surgery.

3.4 Compatibility of Instrument Channels

Verify the inner diameter size of the work channel to ensure that it can smoothly pass through the required treatment equipment, such as biopsy forceps, stone retrieval basket, laser fiber, lithotripter, etc.

3.5 Comprehensive Strength of Suppliers

Assess the R&D capability, quality system (such as ISO 13485 certification), product stability, after-sales technical support capability (including operational training), and sustainable supply guarantee of production enterprises.

4. Main brand information in the market

The global disposable endoscope market is developing rapidly, and disposable cholangioscopy is an important field among them. At present, in addition to international brands such as Boston Scientific, Chinese domestic enterprises have also made significant breakthroughs in the market, launching competitive products such as:

*Shenzhen Hongji Medical Technology Development Co., Ltd.: Its disposable cholangioscope has obtained NMPA approval and EU CE MDR certification, and is one of the representative domestic products.

*Other domestic enterprises, such as Hunan Huaxin Medical and Shanghai Aohua Endoscopy, are also actively laying out in this field and continuously improving product performance.

Domestic products have demonstrated strong competitiveness in image quality (such as reaching tens of thousands of pixels), portability, integration, and cost-effectiveness, and have mature clinical promotion and application value.

5. Conclusion and Suggestions

Disposable cholangioscopy represents an important development direction in biliary interventional diagnosis and treatment technology, which solves the core pain points in infection control, efficiency improvement, and cost optimization in clinical practice through innovative product models. It is recommended that medical institutions:

1. Conduct a comprehensive clinical needs and technical feasibility assessment.

2. Strictly review all qualification documents of suppliers and products.

3. Prioritize arranging samples for clinical trials to evaluate their performance through actual experience.

4. Comprehensively calculate the full lifecycle cost and make scientific decisions.
