Natural orifice transgastric endoscopic surgery promises to eliminate skin incisions and reduce postoperative pain and discomfort. Such an approach provides a distinct benefit as compared with conventional laparoscopy, in which multiple entry incisions are required for tools and camera. Endoscopy currently is the only method for performing procedures through the gastrointestinal tract. However, this approach is limited by instrumentation and the need to pass the entire scope into the patient. In contrast, an untethered miniature robot inserted through the mouth would be able to enter the abdominal cavity through a gastrotomy for exploration of the entire peritoneal cavity. In this study, the authors developed an endoluminal robot capable of transgastric abdominal exploration under esophagogastroduodenoscopic (EGD) control. Under EGD control, a gastrotomy was created, and the miniature robot was deployed into the abdominal cavity under remote control. Ultimately, future procedures will include a family of robots working together inside the gastric and abdominal cavities after their insertion through the esophagus. Such technology will help to reduce patient trauma while providing surgical flexibility.
经自然腔道内镜手术有望消除皮肤切口并减轻术后疼痛与不适。与传统腹腔镜手术相比，这种方法具有显著优势，传统腹腔镜手术需要多个切口来插入工具和摄像头。目前，内镜检查是通过胃肠道进行手术的唯一方法。然而，这种方法受到器械的限制，并且需要将整个内镜插入患者体内。相比之下，通过口腔插入的无束缚微型机器人能够通过胃切开术进入腹腔，以探查整个腹膜腔。在本研究中，作者开发了一种能够在食管胃十二指肠镜（EGD）控制下经胃进行腹腔探查的腔内机器人。在EGD控制下，创建胃切开术，并在远程控制下将微型机器人部署到腹腔中。最终，未来的手术将包括一系列机器人，它们通过食管插入后在胃腔和腹腔内协同工作。这种技术将有助于减少患者创伤，同时提供手术灵活性。
