Medical Laser Fiber — Single-Use or Reusable, Compatible with Quanta Holmium/Thulium Lasers | 200µm / 276µm SMA905

I. Product Introduction

This product is a medical laser fiber compatible with Quanta holmium and thulium laser systems, available in both single-use and reusable versions. The fiber is available in 200µm and 276µm core diameters and features an SMA905 connector design, maintaining stable energy transmission performance in urinary lithotripsy, soft tissue cutting, and minimally invasive endoscopic procedures.

To meet the operational needs of different clinical pathways, this series further offers three fiber end structures: standard flat-tip fiber, ball-tip fiber, and side-emitting fiber, covering a wide range of applications from rigid endoscopy lithotripsy to flexible endoscopy insertion and tissue vaporization.

II. Product Structure Types and Functional Description

Standard Fiber (Flat Tip Fiber)

The standard flat-tip design is used for frontal laser emission, suitable for routine lithotripsy, BPH (benign prostatic hyperplasia) vaporization, soft tissue cutting, and other procedures. It features a simple structure and high light transmission efficiency, making it the most commonly used fiber type in clinical practice. Single-use or reusable versions are available.

Ball-Tip Fiber: The ball-tip structure facilitates smooth insertion into curved flexible endoscope channels, reducing scratches or abrasions to the endoscope's inner wall and lowering the frequency of endoscope adjustments and maintenance costs. Suitable for complex flexible endoscope lithotripsy or clinical scenarios requiring high guidance performance, it is typically offered in a disposable version to ensure endoscope safety.

Side-Firing Fiber: The side-firing design is used for soft tissue vaporization and ablation, including prostate adenoma ablation and soft tissue reconstruction. Side-firing allows for a smooth, intuitive tissue vaporization path and provides a better lateral contact angle. Suitable for departments with high demands for Tm/TFL laser or soft tissue surgery.

III. Application Scenarios

• Urological lithotripsy (Ho:YAG, TFL modes)

• BPH-related surgeries (vaporization and cutting)

• Soft tissue surgeries (coagulation, cutting, vaporization)

• Minimally invasive endoscopic procedures (rigid/flexible endoscope channels)

• Lateral ablation of prostate adenomas (using side-firing fiber)

VI. FAQ

Can it be used with both holmium and thulium fiber lasers?

Yes, all versions are dual-band verified and compatible with Quanta's Ho:YAG and TFL/Tm systems.

How to choose between the three fiber types?

Flat Tip: Routine lithotripsy and soft tissue treatment.

Ball-Tip: Scenarios where flexible endoscope insertion is difficult or the endoscope is easily worn.

Side-Firing: Soft tissue vaporization or surgeries requiring lateral cutting angles.

What is the lifespan of the reusable version?

Lifespan depends on hospital sterilization procedures and usage conditions. It is recommended to follow the manufacturer's maximum usage guidelines.

Is custom-made dome-tip fiber supported?

Disposable dome-tip versions are available, and custom dome diameters can also be made according to the mirror model.

Is it compatible with other laser brands?

In most cases, the interface is compatible, but it is recommended to refer to the fiber optic interface and power limitation specifications of the actual equipment.
