System and Method for Endoluminal Tissue Manipulation

Overview

This invention proposes a novel endoscopic magnetic countertraction system and method that can achieve dynamic tissue traction within the gastrointestinal tract. Compared to conventional ESD, this system provides surgeons with a “second hand” during surgery, which enables more flexible manipulation during ESD procedures, reducing surgical difficulty, shortening surgery time and enhancing surgical safety.

Problem addressed

Endoscopic submucosal dissection (ESD) is an advanced endoscopic surgery used for the non-invasive treatment of early gastrointestinal cancers, allowing for organs to be preserved and improving cure rates. In current ESD, surgeons use a single instrument through a flexible endoscope to perform tissue dissection. The instrument moves along with the endoscope’s view, resulting in technical complications and a long learning curve.

Innovation

The system achieves dynamic tissue traction within the gastrointestinal tract, enableing bimanual operation in ESD procedures
The system utilizes a novel magnetic countertraction device that independent to the endoscope movement.
The magnetic countertraction device of this system can be deployed through the instrument channel of multiple existing flexible endoscope models.

Key impact

The ESD assisted by the system reduces procedure time compared to conventional method
The system reduces the procedural workload for surgeons during ESD procedures
The system provides stable tissue traction during ESD procedures, reducing the risk of muscle injury and perforation
