Although laparoscopic cotton swabs have been used in procedures such as blunt tissue dissection and elevation of organs, fluid maceration is widely known to reduce their original performance. Thus, we developed an anti-maceration laparoscopic surgical cotton swab that is expected to solve this problem by coating the cotton swab with water-resistant resin. This study aimed to determine whether anti-maceration cotton swabs perform better than conventional products.
Fine surface shape analysis of cotton swabs was performed using microfocus X-ray computed tomography, and changes due to fluid absorption of the anti-maceration cotton swabs and pre-existing products were quantitatively compared. As indices, the degree of expansion by maceration and SMD (surface roughness index of the fiber industry showing the size of irregularities on the surface) were evaluated.
The degree of expansion was lower in anti-maceration swabs than in conventional products. Maceration reduced SMD in existing products, whereas the SMD in anti-maceration cotton swabs did not change.
Anti-maceration cotton swabs have a superior performance over conventional products.
虽然腹腔镜棉拭子已用于钝性组织解剖和器官提起等操作，但众所周知，液体浸渍会降低其原有性能。因此，我们开发了一种抗浸渍腹腔镜外科棉拭子，希望通过在棉拭子上涂覆防水树脂来解决这个问题。本研究旨在确定抗浸渍棉拭子是否比传统产品表现更好。
使用微焦点 X 射线计算机断层扫描对棉拭子的精细表面形状进行分析，并定量比较抗浸渍棉拭子和现有产品因吸收液体而发生的变化。作为指标，评估了浸渍膨胀程度和 SMD（纤维工业表面粗糙度指数，显示表面不规则性的大小）。
抗浸渍拭子的膨胀程度低于传统产品。现有产品的浸渍会降低 SMD，而抗浸渍棉拭子的 SMD 则没有变化。
抗浸渍棉拭子的性能优于传统产品。
