Experimental study.
In this study, the ambient temperature of a radiofrequency (RF) electrode tip was compared and analyzed in terms of products, mode, flow quantity, and flow rate.
Endoscopic spine surgery is a widely used operation for degenerative lumbar stenosis and herniated lumbar disc. To perform endoscopic spine surgery, dedicated instruments like a RF generator and electrode are essential.
An evaluation system capable of measuring temperature under equal conditions at a certain distance from the electrode tip was manufactured. The distance between the electrode tip and the temperature sensor was set to 1, 5, and 10 mm. The flow quantities of 0, 50, 100, and 150 mL/min and the flow rates of 0, 0.20, 0.53, and 0.80 m/s were compared and statistically analyzed.
The temperatures measured in the experiments conducted on the four combinations of RF device showed similar values, and showed differences according to the characteristics of each mode of the RF. As the distance between the electrode tip and the temperature sensor increased, the temperature decreased, and as flow quantity or flow rate increased, the temperature decreased. The maximum temperatures differed significantly according to flow quantity, between flow quantities of 0 and 100 mL/min (P = 0.03) and between 0 and 150 mL/min (P ≤ 0.01). The maximum temperatures also differed significantly between the flow rate of 0 m/s, and the flow rates of 0.20, 0.53, and 0.80 m/s, with P ≤ 0.01 in all three comparisons.
This is the first study in which we made a customized RF temperature evaluation system and verified the temperature changes in various environments. When irrigation was performed, we could confirm that the maximum temperature was less than 60°C. Irrigation is considered essential in endoscopic spine surgery.
实验性研究。
在本研究中，对射频（RF）电极尖端的环境温度按产品、模式、流量和流速进行比较与分析。
内镜脊柱手术是治疗退行性腰椎管狭窄症和腰椎间盘突出症广泛应用的手术方式。要进行内镜脊柱手术，诸如射频发生器和电极等专用器械必不可少。
制造了一个能够在距电极尖端一定距离的同等条件下测量温度的评估系统。电极尖端与温度传感器之间的距离设定为1、5和10毫米。比较并统计分析了0、50、100和150毫升/分钟的流量以及0、0.20、0.53和0.80米/秒的流速。
在对四种射频设备组合进行的实验中测得的温度显示出相似的值，并根据射频各模式的特性表现出差异。随着电极尖端与温度传感器之间距离的增加，温度降低；随着流量或流速的增加，温度降低。根据流量不同，最大温度在0和100毫升/分钟之间（P = 0.03）以及0和150毫升/分钟之间（P≤0.01）存在显著差异。最大温度在0米/秒的流速与0.20、0.53和0.80米/秒的流速之间也存在显著差异，在所有这三项比较中P≤0.01。
这是我们首次制作定制的射频温度评估系统并验证各种环境下温度变化的研究。进行冲洗时，我们能够确认最高温度低于60°C。冲洗在内镜脊柱手术中被认为是必不可少的。
