How the Disposable Endoscopic Needle Works
A endoscopic needle is used to inject fluid into the submucosal space to elevate the lesion away from the underlying muscularis propria and create a less flat target for resection.

Application of EMR/ESD accessories
Accessories needed for EMR operation include injection needle, polypectomy snares, hemoclip and ligation device (if applicable) single-use snare probe could be used for both EMR and ESD operations, it also names all-in-one due to its hybird functions. Ligation device could assist polyp ligate, also used for purse-string-suture under endoscop, the hemoclip is used for endoscopic hemostasis and clamping the wound in GI tract.
