Abstract
AIM:To study the reliability and tissue damage of ligasure vessel sealing system during vascular occlusion.
METHODS: Ligasure vessel sealing system was used to seal and cut off the dog blood vessel of different locations and diameters. The diameter of the vessel was measured by a caliper before and after sealing and cutting off, respectively. The bursting pressures were recorded after sealed, and the vascular pathology was performed after the operation.
RESULTS: A total of 12 vessels were sealed successfully by ligasure vessel sealing system, and the success rate was 100%. The mean diameters of the sealed artery and vein were 3.26 mm (1.75-5.22 mm) and 5.42 mm (2.40-9.08 mm), while the bursting pressures were 472 mmHg (380-560 mmHg) and 378 mmHg (250-490 mmHg), respectively. The pathological changes of the sealed vessels caused by ligasure vessel sealing system mainly presented as acute thermal and pressure-induced injury.
CONCLUSION: Ligasure vessel sealing system can effectively seal the vessels, especially the ones 3 mm or larger in diameter.
Key Words: Blood vessel; Hemostasis; Ligasure vessel sealing system

摘要
目的: 研究结扎速(ligasure)血管闭合系统闭合实验狗血管的可靠性及组织损伤程度.
方法: 应用结扎速血管闭合系统切断和闭合实验狗体内不同部位与直径的血管, 切断和闭合血管前用游标尺测量血管直径, 闭合后测定血管破裂时的压力, 术后血管行组织病理学检查.
结果: 结扎速血管闭合系统闭合12条动、静脉, 闭合成功率均为100%, 平均动静脉直径分别是3.26 mm(1.75-5.22 mm)和5.42 mm(2.40-9.08 mm). 成功闭合血管的平均动、静脉破裂压分别是472 mmHg(380-560 mmHg), 378 mmHg(250-490 mmHg). 术后损伤的主要病理改变为组织的急性热和压力损伤.
结论: 结扎速血管闭合系统闭合直径3 mm或更粗的血管有较高的可靠性.

随着腹腔镜技术的飞速发展, 传统的切开及止血方法已经满足不了腹腔镜手术的要求. 目前有关各种止血设备闭合血管的可靠性及组织损伤程度的实验研究少见报道. 结扎速血管闭合系统(ligasure vessel sealing system)是一种新型止血设备, 其独特之处是以组织反应发生器作为电流和电压的能量来源. 我们通过研究结扎速血管闭合系统闭合血管的可靠性及组织损伤程度, 为进行腹腔镜手术的临床医生提供科学依据 ......
