Summary
Clad silica fibre cutting probes offer a cost-effective alternative to sapphire probes, demonstrating good cutting and hemostatic properties. These silica scalpels are heat-tolerant and do not require liquid or gas cooling during laser surgery.
Area of Science:
- Surgical Technology
- Biomedical Engineering
- Laser Medicine
Background:
- Sapphire probes are widely used in laser surgery but are expensive.
- There is a need for cost-effective alternatives with comparable performance.
Purpose of the Study:
- To evaluate the clad silica fibre cutting probe as a viable alternative to sapphire probes.
- To assess the cutting and hemostatic properties of silica scalpels powered by Nd:YAG lasers.
Main Methods:
- A laser scalpel utilizing a clad silica fibre cutting probe was developed.
- The probe was powered by a 10 W continuous wave Nd:YAG laser (1064 nm).
- Cutting and hemostatic capabilities were evaluated.
Main Results:
- The clad silica fibre probe demonstrated good cutting and hemostatic properties.
- Silica scalpels exhibit fair heat tolerance, eliminating the need for liquid or gas cooling.
- The probe is compatible with lasers of various wavelengths, including near-infrared diode lasers.
Conclusions:
- Clad silica fibre cutting probes represent an economical and effective alternative to sapphire probes in laser surgery.
- The heat tolerance of silica scalpels simplifies surgical procedures by removing the need for cooling systems.
- The versatility of the silica probe allows for use with different laser types, expanding its applicability.
