AI Technical Summary
Traditional endoscopic submucosal esophageal tumor resection (STER) is difficult to effectively remove tumors larger than 2 cm in diameter, especially leiomyomas. The snare is difficult to catch and is prone to slipping during dragging, making removal difficult.
The endoscopic device includes an implant and a dragging mechanism. The implant is fixed to the tumor surface by a fixation structure to form a polymer. Flexible elements and magnetic prisms are used to provide uniform traction force and avoid slippage and local stress concentration.
It significantly improved the success rate of removing large tumors, reduced the risk of tumor rupture, protected esophageal tissue, and improved the stability and safety of the surgery.
