Summary
This study introduces a miniature untethered robot for transgastric abdominal exploration, minimizing incisions and pain. This novel endoscopic surgery approach offers enhanced surgical flexibility and reduced patient trauma.
Area of Science:
- Minimally invasive surgery
- Medical robotics
- Gastrointestinal endoscopy
Background:
- Natural orifice transgastric endoscopic surgery offers advantages over conventional laparoscopy by eliminating skin incisions and reducing postoperative pain.
- Current endoscopic procedures are limited by instrumentation and the need to insert the entire scope into the patient.
Purpose of the Study:
- To develop an untethered miniature robot for transgastric abdominal exploration.
- To demonstrate the feasibility of deploying and controlling a miniature robot within the abdominal cavity through a gastrotomy.
Main Methods:
- Development of an endoluminal robot capable of transgastric abdominal exploration.
- Remote control of the miniature robot under esophagogastroduodenoscopic (EGD) guidance.
- Creation of a gastrotomy for robot deployment into the abdominal cavity.
Main Results:
- Successful deployment and remote-controlled exploration of the abdominal cavity using the miniature robot.
- Demonstration of the robot's capability to navigate within the peritoneal cavity after transgastric insertion.
Conclusions:
- The developed endoluminal robot shows promise for transgastric abdominal exploration, potentially reducing patient trauma.
- Future applications may involve a family of robots working collaboratively within the gastric and abdominal cavities for enhanced surgical flexibility.
