外科医生在腹腔镜手术中执行的最后一个程序是通过最小的切口提取标本，旨在通过体外物理实验探索可以通过不同长度和形状的辅助切口提取的标本的最大直径。
我们使用肌肉层的腹壁固定在平方木框架上，以模拟人类的腹壁。从不同的物种中提取不同物种的标本。可以通过，可以通过给定尺寸的切口的最大标本直径。 。
可以用2.4、2.7和3.3 cm的圆形骨术直径提取的最大直径为4.0、4.5和6.0 cm，直径为6.0、8.0和10.0 cm。另外，脐带的长度分别为1 cm，延伸长度分别为1.0、3.0和4.0 cm。 0.0、1.0和2.0厘米。
除了术前成像，手术计划和套管卡位置外，还可以使用辅助切口的形状和长度通过腹腔镜手术来提高样品的提取。

BackgroundThe last procedure performed by the surgeon in laparoscopic surgery is to extract the specimen through the smallest incision possible. This experiment aimed to explore the maximum diameter of specimens that can be extracted through auxiliary incisions of different lengths and shapes by in vitro physical experiments.Materials and methodsWe used the abdominal wall with the muscle layer, fixed on a square wooden frame, to simulate the human abdominal wall. Then, specimen extraction ports were made with circular, inverted Y-shaped and straight-line incisions of different sizes and lengths, and specimens of different sizes were made from tissues of different species. These specimens were extracted from different incisions with a force gauge. The tension value (N) was measured, and records were made of the length or diameter of the smallest auxiliary incision through which a given specimen could pass, as well as the largest specimen diameter that could pass through an incision of a given size. This experiment provides us with preliminary experience-based knowledge of how to choose the appropriate auxiliary incision for surgical specimen extraction according to the diameter of the specimen.ResultsThe maximum diameters of specimens that could be extracted with circular ostomy diameters of 2.4, 2.7 and 3.3 cm were 4.0, 4.5 and 6.0 cm, respectively. Specimens with diameters of 6.0, 8.0 and 10.0 cm could be extracted through inverted Y-shaped incisions with a length around the umbilicus of 1 cm and an extension length of 1.0, 3.0, and 4.0 cm, respectively. Moreover, these same specimens could be extracted through inverted Y-shaped incisions with a length around the umbilicus of 2 cm and extension lengths of 0.0, 1.0 and 2.0 cm. Tough tissue specimens (made from chicken gizzards) with diameters of 1.0, 2.0, 4.0 and 6.0 cm, respectively, could be removed through straight-line incisions measuring 1.0, 2.0, 3.0 and 4.0 cm in length.ConclusionAlong with preoperative imaging, surgical planning and trocar position, the shape and length of auxiliary incisions can be used to improve the extraction of specimens via laparoscopic surgery.
