Prospective single-arm trial on feasibility and safety of an endoscopic robotic system for colonic endoscopic submucosal dissection.

Background: The development of the EndoMaster "Endoluminal Access Surgical Efficacy" (EASE) system aims to enhance the safety and efficacy of colonic endoscopic submucosal dissection (ESD) through two flexible robotic arms. This is the first clinical trial to evaluate the performance of colorectal ESD using EndoMaster.

Method: Patients with early mucosal colorectal neoplasia that was not suitable for en bloc resection with snare-based techniques were recruited.

Feasibility of a low-cost magnet tracking device in confirming nasogastric tube placement at point of care, a clinical trial.

An affordable and reliable way of confirming the placement of nasogastric tube (NGT) at point-of-care is an unmet need. Using a novel algorithm and few sensors, we developed a low-cost magnet tracking device and showed its potential to localize the NGT preclinically. Here, we embark on a first-in-human trial.

Can the Shape of a Planar Pathway Be Estimated Using Proximal Forces of Inserting a Flexible Shaft?

The shape information of flexible endoscopes or other continuum structures, e.g., intro-vascular catheters, is needed for accurate navigation, motion compensation, and haptic feedback in robotic surgical systems.

A Low-Cost, Point-of-Care Test for Confirmation of Nasogastric Tube Placement via Magnetic Field Tracking.

In this work, we aim to achieve low-cost real-time tracking for nasogastric tube (NGT) insertion by using a tracking method based on two magnetic sensors. Currently, some electromagnetic (EM) tracking systems used to detect the misinsertion of the NGT are commercially available. While the EM tracking systems can be advantageous over the other conventional methods to confirm the NGT position, their high costs are a factor hindering such systems from wider acceptance in the clinical community.
