A new robotic-assisted flexible endoscope with single-hand control: endoscopic submucosal dissection in the ex vivo porcine stomach

Abstract

The RAFE that we developed enabled an expert endoscopist to perform the ESD procedure without any problems and allowed a non-endoscopist to control the endoscope more easily and quickly than a manual endoscope. The RAFE is expected to undergo further development.

Development of a Novel Gastrointestinal Endoscopic Robot Enabling Complete Remote Control of All Operations: Endoscopic Therapeutic Robot System (ETRS)

“…These devices are manually driven by a wire system connected to the handles [13], whereas the ETRS is driven by computer control. RAFE is similar to EOR of our previous robot system [14]. RAFE is more compact than EOR.…”

“…The MASTER [1–3], EndoSAMURAI [4–6], 3D-printed overtube system [12], and 2.6 mm articulating devices [13] are included in the former. EOR and the robotic-assisted flexible endoscope (RAFE) [14] are included in the latter. ETRS is the only platform to combine both of these operations.…”

“…In the reports of ESD using RAFE [14], the 3D-printed overtube system [12], and 2.6 mm articulating devices [13], dissection time and specimen size were shown. We compared the mean dissection speed of these systems and ETRS.…”

Gaining traction: pulley-ing your weight during endoscopic submucosal dissection

“…20,21 The use of magnetic anchors and robotassisted countertraction are additional examples of attractive innovative ideas that have been proposed; yet, further studies are needed to establish their utility in clinical practice. 22 More recently, novel interventional platforms for endoscopic resection of colonic lesions have become commercially available. The double-balloon endoluminal system (DiLumen, Lumendi, Westport, Conn, USA) is an overtube-assisted platform with 2 independent inflatable balloons that can be used over a colonoscope.…”

Intelligent Information-Guided Robotic Surgery

“…We have also been developing flexible endoscopic platforms for ESD in manually driven version [47,48] (Figure 10) and motorized version [49] (Figure 11). They composed of conventional flexible endoscope, two 2.6-mm articulating instruments, and an additional channel.…”
