Abstract

INTRODUCTION

Since 2012 Elmed has been working on a robot specifically designed for flexible ureteroscopy. After the first version of Avicenna Roboflex, a second version was developed in 2015, with significant changes especially in the irrigation system. We consider mandatory for the endourologist that works with the Avicenna Roboflex be aware of the functioning of the irrigation system.

MATERIALS AND METHODS

We connected a container to the pump's irrigation system and measured the quantity of saline per second delivered by each speed setting, with/without the flush in five different modalities: pump on its own, pump with ureteroscope, with two laser fibers, with 1.9 Fr basket, and with a Terumo guidewire.

RESULTS

The highest mean flow-rates were observed in the 200- micrometer laser fiber, after the pump on its own. Median flowrates for all speed settings were significantly higher for the pump on its own than for the URS in both flushed and nonflushed modes (p = 0.045, p = 0.039 respectively). There was no statistically significant difference in median flow-rates between the guide wire and basket in all of the speed settings (p = 0.932 and p = 0.977). For both laser fibers there was no statistically significant difference between the median flow rate on both nonflush and flush modes. (p = 0.590 & p = 0.590). There was a linear correlation between the speed setting and the increase measured with the flush-option for pump only measurements (r = 0.602, p = 0.038). There was no statistically significant difference between laser fibers and the pump on its own on the increase of flow rate with flush mode. (p = 0.443 for the 272- micrometer fiber and p = 0.219 for the 200-micrometer fiber).

CONCLUSION

The irrigation system of the new Avicenna Roboflex is optimized compared to the previous version. However other more complex studies concerning the live flow/pressure relationship are needed before firm conclusions can be made.

摘要

引言

自2012年以来，埃尔梅德公司一直在研发一款专门为柔性输尿管镜检查设计的机器人。在阿维森纳Roboflex的第一个版本之后，2015年开发了第二个版本，特别是在冲洗系统方面有重大变化。我们认为，使用阿维森纳Roboflex的泌尿外科医生必须了解冲洗系统的功能。

材料与方法

我们将一个容器连接到泵的冲洗系统，并测量在五种不同模式下（单独使用泵、泵与输尿管镜一起、与两根激光纤维一起、与1.9Fr篮子一起、与泰尔茂导丝一起），每种速度设置每秒输送的生理盐水数量，有/无冲洗。

结果

在单独使用泵之后，在200微米激光纤维中观察到最高平均流速。在冲洗和未冲洗模式下，单独使用泵时所有速度设置的中位流速均显著高于输尿管镜检查时的中位流速（分别为p = 0.045，p = 0.039）。在所有速度设置下，导丝和篮子之间的中位流速没有统计学显著差异（p = 0.932和p = 0.977）。对于两根激光纤维，在未冲洗和冲洗模式下的中位流速之间没有统计学显著差异（p = 0.590和p = 0.590）。在仅对泵进行测量时，速度设置与冲洗选项下测量的增加量之间存在线性相关性（r = 0.602，p = 0.038）。在冲洗模式下流速增加方面，激光纤维与单独使用泵之间没有统计学显著差异（272微米纤维的p = 0.443，200微米纤维的p = 0.219）。
