The endoscope rod lens is a high-precision optical component, usually made of special glass or optical crystal materials. Its core function is to transmit and amplify images. Compared with traditional lens groups, microrod lenses have the advantages of small size, high light transmittance, and low imaging distortion, and can achieve higher quality optical transmission in the narrow body of the endoscope.

In the endoscope system, micro rod lenses are usually used as the core imaging module, in conjunction with CCD/CMOS sensors or optical fibers, to transmit real-time images in the patient's body to the display, helping doctors to clearly observe the lesions. Especially in rigid endoscopes (such as laparoscopes and arthroscopes), the imaging quality of micro rod lens directly determines the accuracy and safety of the operation.

Technical advantages: clearer, more stable, and more durable.

In clinical applications, the upgrade of micro rod lens enables endoscopes to:

1. Improve the detection rate of lesions - high-resolution imaging can clearly show early tumors, tiny blood vessels and other subtle structures;

2. Enhance surgical safety - reduce optical distortion, help doctors accurately avoid important tissues such as nerves and blood vessels;

3. Extend the life of the equipment - high temperature and high pressure design, suitable for multiple disinfection and long-term use.

Wide range of application scenarios

At present, endoscopes equipped with micro rod lenses have been widely used in: gastroenterology(gastroscopy, colonoscopy), minimally invasive surgery(laparoscopy, thoracoscopy), urology(ureteroscopy, nephroscope), orthopedics(arthroscopy), otolaryngology(sinusoscope, laryngoscope)

Taking laparoscopic surgery as an example, the high-definition imaging of the endoscope rod lens enables doctors to complete complex operations in an incision of only a few millimeters, greatly reducing the patient's bleeding and postoperative recovery time.

In recent years, with the improvement of domestic optical technology and precision manufacturing level, domestic micro-rod endoscopes and supporting endoscope systems are gradually breaking through technical barriers. Industry experts pointed out that the iteration of endoscope rods will further promote the development of domestic endoscopes towards intelligence and ultra-high definition, and combine AI-assisted diagnosis, 3D imaging and other technologies to bring more possibilities for minimally invasive surgery.

The new generation of endoscope rod products has entered the mass production stage, and cooperated with many hospitals to promote clinical optimization. In the future, it is expected to become an important boost for domestic high-end endoscopes to "go overseas".
