Endoscopic submucosal dissection-assistance robot: a miniature surgical manipulator for endoscopic submucosal dissection
Authors
Gefördert durch: 2022 Key Research and Development Plan Project of the Science and Technology Department of Anhui Province 9021240206 Clinical Trial: Registration number (trial ID): ChiCTR2300077031, Trial registry: Chinese Clinical Trial Registry, Type of Study:
One-handed operation and gravity-induced blind dissection are technical difficulties in endoscopic submucosal dissection (ESD) procedures [1]. In order to reduce the difficulty of the procedure and minimize the risk of perforation and bleeding, we have developed a microsurgical manipulator, the ESD-assistance robot, which provides a “second hand” with auxiliary traction, clamping, and fixation functions during procedures.
The ESD-assistance robot is composed of four main components: an end cap sheath tube, manipulator, servo driver, and command controller ([Fig. 1]). When in use, the end cap sheath tube is fitted at the front end of the endoscope, and the endoscope is extended to extend the sheath tube. When performing dissection, the micromanipulator is voice controlled to move in forward/backward and clockwise/counterclockwise rotational directions, to bend forward/backward, and to open/close the mouth of the clamp ([Fig. 2]); auxiliary traction is applied to the pathologic tissue, maintaining the surgical field of view, thereby improving the dissection speed and reducing the difficulty of the procedure.
A 60-year-old man was admitted to hospital with gastric cardia mucosal lesions and underwent diagnostic excision by ESD. During the procedure, traction from the ESD-assistance robot was used to obtain a clear submucosal field of vision, and to facilitate dissection, hemostasis, and submucosal injection ([Fig. 3]), which together improved surgical efficiency ([Video 1]).
