本研究应用便携式笔记本一次性大孔道内镜完成猪模拟战创伤模型内弹片的发现及取出；肝脏、胃肠道伤口造模及内镜下止血夹止血的有效性、安全性评估，探究在紧急野外腹部战创伤中替代腹腔镜技术实现超级微创内镜下异物取出及止血。

利用巴马猪分别构建腹部弹片刺伤肝脏及消化道模型，选取气腹机构造气腹模型，便携式笔记本一次性大孔道内镜进行内镜下弹片取出及止血，选取止血夹进行止血，共选取3头巴马猪，分别进行重复实验，计算发现弹片时间、弹片取出成功率及失败率、弹片取出时间、肝脏及消化道止血成功率及失败率、止血所用时间、止血夹使用情况、内镜操作满意情况等。

使用便携式笔记本一次性大孔道内镜系统进行异物发现及取出、内镜下止血各3次，均成功。便携式笔记本一次性大孔道内镜系统发现及取出弹片模型时间分别为(254.33±14.74)s、(174.00±12.20)s ；便携式笔记本一次性大孔道内镜在腹腔发现出血部位及止血时间分别为(194.00±10.74)s、(258.00±12.09)s；实验过程中，操作者对新型便携式笔记本内镜系统的操作过程满意，并且无不良事件和器械缺陷发生。

便携式笔记本一次性大孔道内镜有用于紧急野外腹部战创伤所致腹腔内异物取出及腹腔内出血止血的潜力。

In this study, we applied a portable laptop disposable large-channel endoscope to complete the discovery and removal of shrapnel in a porcine simulated war trauma model; liver and gastrointestinal wound modeling and endoscopic hemostatic clips for hemostasis were evaluated for effectiveness and safety, and we explored alternatives to laparoscopic techniques to achieve super-minimally invasive endoscopic foreign body removal and hemostasis in emergency field abdominal war trauma.

Bama pigs were used to construct abdominal shrapnel injury models of the liver and digestive tract, respectively; the pneumoperitoneum mechanism was selected to create a pneumoperitoneum model; a portable laptop disposable large-aperture endoscope was used to carry out endoscopic shrapnel removal and hemostasis, and hemostatic clips were used to carry out hemostasis; a total of three Bama pigs were selected to carry out the repeated experiments, and the time to discover the shrapnel, the success rate of shrapnel removal, the failure rate of the shrapnel removal, the time to remove the shrapnel, the success rate of hemostasis of the liver and the digestive tract and failure rate, time used for hemostasis, use of hemostatic clips, and satisfaction with endoscopic operation.

Foreign body discovery and removal and endoscopic hemostasis were successfully performed three times each using a portable laptop disposable large-channel endoscopic system.Portable laptop disposable large-channel endoscopic system discovery and removal of the shrapnel model time were (254.33±14.74)s, (174.00±12.20)s; portable laptop disposable large- channel endoscopic discovery of the bleeding site in the abdominal cavity and the time of hemostasis were (194.00±10.74)s, (258.00±12.09)s, respectively; in the course of the experiments, the operators were satisfied with the procedure of the new portable laptop endoscopic system and there were no adverse events and device defects.

Portable laptop disposable large orifice endoscopy has the potential to be used for the removal of intra-abdominal foreign bodies due to emergency field abdominal combat trauma and the hemostasis of intra-abdominal hemorrhage.
