In the current industrial inspection and clinical medical fields, the application of endoscopes has become very widespread. However, there are significant differences in how these two fields should choose the appropriate endoscopes. The following is a comprehensive analysis of the selection of endoscope types, considering both clinical and industrial scenarios, and systematically organizing it from core parameters to application environments:



1. Clearly define the core requirements

Application of Field Distinction

Industrial Inspection: Preferentially select models with probe diameters matching the detection aperture. For example, a 3.9-4mm probe is recommended for a 5mm channel, and a probe capable of withstanding temperatures above 200℃ is required in high-temperature environments.

Medical Applications: Hard endoscopes such as laparoscopes and arthroscopes. Suitable for sterile invasive operations. Soft endoscopes such as gastroscopes and bronchoscopes require a micro imaging module to support natural channel exploration.

Functional requirements


Industrial scenario: Attention should be paid to the type of lighting, distinguishing between white light, ultraviolet light, and infrared light sources. The position of the light source is divided into front-mounted and rear-mounted.

Medical scenario: For complex surgical procedures, 4K/3D imaging or fluorescence navigation functions are required. For grassroots medical treatment, an integrated device can be selected to simplify the operation.



2. Technical Parameter Comparison

Industrial Inspection Priority

Resolution: Requires a resolution of 1080P or higher. Low-light sensors should be equipped to ensure clear imaging in dim environments.

Probe Flexibility: Recommended 360° rotating probe design to effectively reduce detection blind zones.

Signal Transmission: Must have anti-electromagnetic interference capability and the transmission delay should be controlled within 0.1 seconds.



Medical Application Priority

Resolution: 4K ultra-clear imaging combined with fluorescence navigation technology to enhance the recognition rate of minor lesions.

Probe Flexibility: The viewing angle should be greater than 70°, and the field of view should cover both wide-angle and narrow-angle modes to meet the needs of different surgical fields.

Signal Transmission: Separated equipment needs to optimize the stability of multi-module collaboration to avoid signal interruption during surgery.



3. Environmental Adaptability Assessment

Industrial environment

For oily environments, use anti-oil glass lenses; for radiation scenarios, customize radiation-resistant casings.

When detecting in narrow spaces, choose pipelines with a length-to-diameter ratio greater than 100 to improve passability.


Medical environment

Scenarios with high infection risks, such as the respiratory department, tend to use disposable detachable endoscopes.

For deep tissue exploration, 3D imaging combined with infrared/YE multi-spectral technology is required as support.



4. Cost and Maintenance Considerations

Industrial equipment: Posterior fiber optic light sources have a long lifespan but are costly, suitable for high-frequency inspections; front-mounted LEDs are suitable for short-term projects to reduce costs.


Medical equipment: Primary institutions recommend integrated endoscopes, with low procurement costs, while tertiary hospitals can choose modular systems with detachable components, which can support the expansion of multiple types of scopes.


Maintenance costs: Models with a diameter of less than 5mm for medical endoscopes have a 30% increase in maintenance difficulty. Industrial probes are recommended to be paired with tungsten wire woven protective layers to extend their lifespan.



5. Development Trend References

Intelligentization: Medical endoscopes are transitioning to CMOS sensors, gradually replacing CCD technology to achieve higher dynamic range.

Lightweighting: Industrial inspection equipment uses photoelectric conversion components, with the probe diameter compressed to below 5mm.

Function integration: The medical field is promoting dual-mirror fusion systems, such as endoscopes + laparoscopes, to reduce instrument switching during surgery.

Through the cross-analysis of these dimensions, it is possible to match the required scenarios specifically, balance performance and cost, and select the optimal solution.
