Introduction:
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.
Material And Methods:
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.
Results:
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.
Conclusions:
Anti-maceration cotton swabs have a superior performance over conventional products.
Insights
New anti-maceration laparoscopic surgical cotton swabs resist fluid damage, maintaining performance during procedures. These innovative swabs offer superior functionality compared to conventional products, enhancing surgical outcomes.
Area of Science:
- Surgical Innovation
- Biomaterials Science
Background:
- Laparoscopic cotton swabs are crucial for surgical tasks like tissue dissection.
- Fluid absorption (maceration) significantly degrades the performance of conventional cotton swabs.
- A novel anti-maceration cotton swab coated with water-resistant resin was developed.
Purpose of the Study:
- To evaluate the performance of anti-maceration cotton swabs compared to conventional ones.
- To quantify the effects of fluid absorption on swab structure and performance.
Main Methods:
- Microfocus X-ray computed tomography was used for fine surface shape analysis.
- Quantitative comparison of anti-maceration and conventional swabs after fluid absorption.
- Evaluation of degree of expansion and surface roughness index (SMD) as performance metrics.
Main Results:
- Anti-maceration swabs exhibited a lower degree of expansion when exposed to fluid.
- Conventional swabs showed reduced SMD after maceration, indicating performance degradation.
- SMD of anti-maceration swabs remained unchanged, preserving their structural integrity.
Conclusions:
- Anti-maceration cotton swabs demonstrate superior performance over conventional products.
- The water-resistant coating effectively prevents maceration-induced degradation.
- These enhanced swabs represent a significant improvement for laparoscopic surgery.
