| Background: Endoscopic procedures such as endoscopic full-thickness resection and endoscopic obesity surgery have been developed, recently, we have developed a novel anchor-type suturing device. Methods: This novel suturing device consists of a forceps-type anchor retention device that can be inserted into the forceps opening (3.8mm) of a single channel endoscope and a suture retention device. First, the wall is grasped and pulled through full-thickness layers with a grasper integrated into the forceps. Second, a puncture needle is used to penetrate the raised wall through all layers, the anchor is released outside the wall, and only the anchor outside the wall is retained by retracting the puncture needle. Third, the anchors are stored inside the forceps, and multiple anchors can be placed by continuous punctures, and finally the suture can be fixed by tightening the thread. Results: Experiments were conducted on live pig models. Multiple experiments showed that a stitch could be sutured in an average of 100 seconds, and observation from the wall of the peritoneal side showed that it was possible to suture without leaks or damage to the surrounding organs. In addition to reliable and easy suturing of full-thickness layers. Conclusions: Although challenges remain, the development of such suturing techniques is expected to broaden the direction and indications for therapeutic endoscopy in the future. |
