Effects on Laser Fibers after Using the ‘Laser Holder’-Assisted Laser Fiber Cleavage
Abstract
Objective: The precise cleavage of laser fibers is critical in urological surgery. However, traditional manual cleaving methods using ceramic scissors and a cleaving pen often result in inefficient cuts, affecting light dispersion and energy transmission. This study aimed to compare the effects of cleaved laser fibers with ceramic scissors and cleaving pen, combined with and without the use of the Laser Holder.
Material and Methods: A new 272 µm reusable laser fiber with a base power output of 1 W (0.2 J, 5 Hz) was evaluated for the quality of laser light dispersion, power output, and fiber tip morphology using ceramic scissors and a cleaving pen, compared with and without the Laser Holder. The results of the experimental comparisons between groups were analyzed using the chi-square test, two-way ANOVA, and Fisher’s exact test.
Results: The Laser Holder significantly improved light dispersion (p-value<0.01), with the combination of cleaving pen and Laser Holder showing the best result (p-value<0.0125). Power output remained unaffected (p-value>0.05), with the cleaving pen combined with the laser holder exhibiting the highest efficiency (91.38%).
Conclusion: The Laser Holder significantly enhances the precision of the cleaved laser fiber, aligning with surgical standards, regardless of the cleaving instrument used. Cleaving pens provide optimal energy transmission. This knowledge may improve and simplify the handling of laser fibers in urological surgeries.
