Abstract

Through an ex vivo experimental study, we aimed to compare the effects of the Ho: YAG laser Virtual Basket (VB™) modulation and a Thulium fiber laser (TFL) on kidney tissue in different environments and using laser configurations. The 100 W Ho: YAG (Cyber Ho, Quanta System, Italy) and 60 W TFL (Fiber Dust, Quanta System, Italy) laser devices were used. The following laser settings were selected: power in the range of 10-60 W, frequency of 20-40 Hz, and energy of 0.5-1-1.5 J. A medium pulse duration of 600 µsec was used for VB™, while short (spdTFL; 50 µsec) and long (lpdTFL; 15,000 µsec) were used for TFL. The tissue's incision depth (ID), vaporization area (VA), coagulation area (CA), total laser area (TLA = VA + CA), surface section (SS), and lateral effect (LE) were measured. In total, 108 experiments were conducted. No statistically significant difference in mean VA, TLA, ID, LE, or SS was observed between VB™, spdTFL, and lpdTFL in the low-power output group in saline (p > 0.05). However, the mean CA was statistically significantly higher for VB™ (p = 0.005). In saline and high-power output group, the mean VA, CA, TLA, LE, and ID were higher when using lpdTFL than other pulse durations (p = 0.001, p = 0.001, p = 0.001, p = 0.006, and p = 0.001, respectively). Similar to lpdTFL, VB™ may provide controlled dissection and incision as well as haemostasis. At different laser settings, the individual effects of laser properties (such as pulse length, energy and frequency) on tissue may be more significant.

Ho: YAG 激光器虚拟 Basket™ 脉冲调制与铥光纤激光器对肾组织影响的比较--一项体内外实验研究。

通过一项体内外实验研究，我们旨在比较 Ho：YAG 激光器虚拟篮（VB™）调制和铥光纤激光器（TFL）在不同环境和激光配置下对肾组织的影响。使用了 100 W Ho：YAG（Cyber Ho，意大利 Quanta System 公司）和 60 W TFL（Fiber Dust，意大利 Quanta System 公司）激光设备。VB™ 采用 600 微秒的中等脉冲持续时间，TFL 采用短脉冲（spdTFL；50 微秒）和长脉冲（ldTFL；15,000 微秒）。对组织的切口深度 (ID)、汽化面积 (VA)、凝固面积 (CA)、总激光面积 (TLA = VA + CA)、表面截面 (SS) 和横向效应 (LE) 进行了测量。总共进行了 108 次实验。在生理盐水中的低功率输出组中，VB™、spdTFL 和 lpdTFL 的平均 VA、TLA、ID、LE 或 SS 均无明显统计学差异（p > 0.05）。然而，VB™ 的平均 CA 在统计学上明显更高（p = 0.005）。在生理盐水和高功率输出组中，使用 lpdTFL 时的平均 VA、CA、TLA、LE 和 ID 均高于其他脉冲持续时间（分别为 p = 0.001、p = 0.001、p = 0.001、p = 0.006 和 p = 0.001）。与 lpdTFL 相似，VB™ 可提供可控的剥离和切口以及止血。在不同的激光设置下，激光特性（如脉冲长度、能量和频率）对组织的影响可能更为显著。

期刊介绍： Lasers in Medical Science (LIMS) has established itself as the leading international journal in the rapidly expanding field of medical and dental applications of lasers and light. It provides a forum for the publication of papers on the technical, experimental, and clinical aspects of the use of medical lasers, including lasers in surgery, endoscopy, angioplasty, hyperthermia of tumors, and photodynamic therapy. In addition to medical laser applications, LIMS presents high-quality manuscripts on a wide range of dental topics, including aesthetic dentistry, endodontics, orthodontics, and prosthodontics. The journal publishes articles on the medical and dental applications of novel laser technologies, light delivery systems, sensors to monitor laser effects, basic laser-tissue interactions, and the modeling of laser-tissue interactions. Beyond laser applications, LIMS features articles relating to the use of non-laser light-tissue interactions.
