Laparoscopic surgery requires specially designed instruments. Bowel tissue damage is considered one of the most serious forms of lesion, specifically perforation of the bowel.
An experimental setting was used to manipulate healthy pig bowel tissue via two vacuum instruments. During the experiments, two simple manipulations were performed for both prototypes by two experienced surgeons. Each manipulation was repeated 20 times for each prototype at a vacuum level of 60 kPa and 20 times for each prototype at a vacuum level of 20 kPa. All the manipulations were macroscopically assessed by two experienced surgeons in terms of damage to the bowel.
In 160 observations, 63 ecchymoses were observed. All 63 ecchymoses were classified as not relevant and negligible. No serosa or seromuscular damages and no perforations were observed.
Vacuum instruments such as the tested prototypes have the potential to be used as grasper instruments in minimally invasive surgery.
腹腔镜手术需要专门设计的器械。肠组织损伤被认为是最严重的损伤形式之一，特别是肠穿孔。
本实验通过两个真空仪器操作健康猪的肠组织。在实验过程中，两位经验丰富的外科医生对两个原型进行了两种简单的操作。每个操作在 60kPa 和 20kPa 的真空度下，每个原型重复 20 次。两位经验丰富的外科医生对肠组织的损伤情况进行了宏观评估。
在 160 次观察中，观察到 63 处瘀斑。所有 63 处瘀斑均被归类为无关紧要和可忽略不计。没有观察到浆膜或浆肌层损伤和穿孔。
真空仪器，如经过测试的原型，有可能作为微创外科中的抓握器械使用。
