Abstract

Background and objectives: With the continued development of advancements in minimally invasive surgery, aspirators have become increasingly slenderer to enable smooth insertion into narrow access ports. However, high-viscosity fluids, such as ovarian cyst contents and blood clots, may be difficult to aspirate using slender aspirators. Therefore, we developed a novel emulsification suction irrigator. This study aimed to verify the feasibility of this suction device and compare its suction efficiency with that of conventional devices.

Methods: The newly developed emulsification suction irrigator consists of a spoon-shaped tip and double-lumen shafts for water delivery and suction, which enable the aspiration of emulsified contents. We evaluated the aspiration efficiency by comparing the aspiration rates between the emulsification suction irrigator and conventional single-lumen suction irrigator. Three types of content were compared: viscous (mucinous cyst), highly fibrotic (blood clots), and content containing fat and debris (dermoid cysts). Each of the 3 types of fluids was examined in an artificial model.

Results: The emulsification suction irrigator significantly improved the suction efficiency compared with that of the single-lumen suction irrigator. For the 3 types of content, a significant difference in the median aspirated mass was found between the emulsification suction irrigator with water supply and single-lumen suction irrigator (P < .001).

Conclusion: Our new emulsification suction irrigator improved the removal efficiency of highly viscous liquids in artificial models.

一种用于高粘度流体的乳化吸力冲洗器。

背景和目的：随着微创手术技术的不断进步，吸引器变得越来越纤细，能够顺利插入狭窄的入口。然而，高粘度液体，如卵巢囊肿内容物和血凝块，可能难以使用细长的吸引器吸引。为此，我们研制了一种新型的乳化吸灌器。本研究旨在验证该吸力装置的可行性，并将其与常规装置的吸力效率进行比较。方法：新研制的乳化吸洗器由勺形尖端和双管轴组成，用于输水和吸水，可以吸出乳化内容物。我们通过比较乳化吸灌器和传统单腔吸灌器的吸出率来评估吸出效率。比较了三种类型的内容物：粘性（粘液囊肿）、高度纤维化（血凝块）和含有脂肪和碎片的内容物（皮样囊肿）。在人工模型中对这三种流体进行了检测。结果：与单腔吸洗器相比，乳化吸洗器明显提高了吸洗效率。对于3种内容物，有水的乳化吸灌器与单腔吸灌器的中位吸出质量差异有统计学意义（P .001）。结论：新型乳化吸力冲洗器提高了人工模型高黏性液体的去除效率。
