摘要: 目的 评价新型低温等离子手术系统(NTS-100)的血管凝固止血效果。 方法 12只巴马小型猪按体质量大小进行编号，应用软件随机分为3组，比较新型低温等离子手术系统(NTS-100)、高频电刀(Valley)、低温等离子手术刀(PEAK)对肠系膜血管及胃、脾、腹壁静脉的凝固止血效果。 结果 新型低温等离子手术系统对平均直径1.5 mm的肠系膜血管凝血成功率100%，延迟出血率0，与高频电刀及低温等离子手术刀差异无统计学意义(P> 0.05)；新型低温等离子手术系统对平均直径3.56 mm的胃、脾及腹壁静脉凝血成功率100%，延迟出血率0，最大可凝固4.53 mm腹壁静脉，与高频电刀及低温等离子手术刀差异无统计学意义(P> 0.05)。 结论 新型低温等离子手术系统在肠系膜血管及胃、脾、腹壁静脉凝固止血手术中与高频电刀和低温等离子手术刀的止血效果相当。

Abstract: Objective To evaluate the sealing potential of a new surgical system which applies low temperature plasma (NTS-100) in mesenteric vascular, gastric vein, splenic vein and abdominal wall vein． Methods Twelve piglets were randomly divided into three groups, and each group underwent operation using NTS-100, Valley or PEAK surgical systems, respectively． The effectiveness of sealing in the mesenteric vascular, the gastric vein, the splenic vein and the abdominal wall vein was evaluated and compared． Results Successful sealing rate of NTS-100 on the mesenteric vascular with average diameter of 1．5 mm was 100%, and the delayed bleeding rate was 0． No statistically significant difference was found when compared with Valley and PEAK (P> 0．05); Successful sealing rate of NTS-100 on the gastric vein, splenic vein and abdominal wall vein with average diameter of 3．56 mm was 100%, and the delayed bleeding rate was 0． Vessels with the greatest diameter of 4．53 mm could be sealed successfully． While, there was no statistically significant difference when compared with Valley and PEAK (P> 0．05)． Conclusion A new surgical system which applies low temperature plasma (NTS-100) has favorable effectiveness on sealing vascular when compared with Valley and PEAK in the operations on the mesenteric vascular, the gastric vein, the splenic vein and the abdominal wall vein． -
