To evaluate the tissue injury caused by the force applied by the roboticassisted graspers of avatera robotic surgical system on bowel tissue.
An experimental in vivo porcine model with 1 pig was conducted. After a standard transperitoneal setup of the avatera robotic surgical system, different laparoscopic and robotic graspers were used on the bowel with maximum force applied each time. Robotic atraumatic grasper, laparoscopic right angle grasper, laparoscopic curved grasper, and laparoscopic atraumatic grasper were used. After using all graspers, the pig was sacrificed. The bowel segments were resected and sent for histological analysis.
The pathologist reported that all the graspers caused signs of acute inflammation without any irreversible damage or signs compatible with ischemia of the tissue. No significant difference in histology was observed between the graspers.
No permanent damage was caused by graspers, except for acute, reversible inflammation. Concluding, the avatera grasper could be safe to use on bowel segments, independent of the applied pressure.
评估阿瓦特拉机器人手术系统的机器人辅助抓钳对肠组织施加的力所导致的组织损伤。
以1头猪进行了一项体内实验模型。在对阿瓦特拉机器人手术系统进行标准的经腹设置后，每次以最大力使用不同的腹腔镜和机器人抓钳作用于肠管。使用了机器人无创伤抓钳、腹腔镜直角抓钳、腹腔镜弯形抓钳和腹腔镜无创伤抓钳。使用完所有抓钳后，对猪实施安乐死。切除肠段并送去进行组织学分析。
病理学家报告称，所有抓钳均引起急性炎症迹象，但无任何不可逆损伤或与组织缺血相符的迹象。各抓钳之间在组织学上未观察到显著差异。
抓钳除了引起急性、可逆性炎症外，未造成永久性损伤。因此，阿瓦特拉抓钳在肠段上使用可能是安全的，与施加的压力无关。
