Surgical sutures are the most well-known surgical biomaterial device for ligating blood vessels. The primary goal of wound closure is to align wound margins to provide a closed and stable environment. Sutures with lesser tensile strength are susceptible to break throughout the healing process due to edema. To evaluate the tensile strength of absorbable and nonabsorbable suture materials after immersion in fruit juices. In this study, eight samples of commercially available sutures such as black silk and vicryl were divided into two groups: sample -1 were immersed in grape juice and sample -2 were immersed in lemon juice for 1 week. Universal testing machine INSTRON E300 UTM was used to test the tensile strength of various suture materials. The data are statistically analyzed using an independent -test. The < 0.05 was considered to be statistically significant. The mean of vicryl suture after immersion in grape and lemon juice was found to be 34.445 and 43.39; the mean value of black silk after immersion in grape and lemon juice was found to be 36.95 and 33.1. The tensile strength of black silk was slightly lower than the vicryl. Independent sample -test showed that = 0.561 (>0.05) which is statistically insignificant. Vicryl suture tested to have the highest tensile strength along with excellent knot holding capacity than black silk suture after immersion in fruit juices.
手术缝线是用于结扎血管的最为人熟知的外科生物材料装置。伤口闭合的主要目标是使伤口边缘对齐，以提供一个封闭且稳定的环境。抗拉强度较低的缝线在整个愈合过程中容易因水肿而断裂。为了评估可吸收和不可吸收缝线材料浸泡在果汁后其抗拉强度的情况。在本研究中，将八个市售缝线样本（如黑色丝线和维可牢尼龙缝线）分为两组：样本 -1 浸泡在葡萄汁中，样本 -2 浸泡在柠檬汁中，浸泡 1 周。使用万能材料试验机 INSTRON E300 UTM 来测试各种缝线材料的抗拉强度。数据采用独立样本 t 检验进行统计分析。P < 0.05 被认为具有统计学显著性。发现维可牢尼龙缝线浸泡在葡萄汁和柠檬汁后的平均值分别为 34.445 和 43.39；黑色丝线浸泡在葡萄汁和柠檬汁后的平均值分别为 36.95 和 33.1。黑色丝线的抗拉强度略低于维可牢尼龙缝线。独立样本 t 检验显示 P = 0.561（>0.05），这在统计学上不显著。浸泡在果汁后，维可牢尼龙缝线的抗拉强度最高，并且打结把持能力优于黑色丝线缝线。
