Disposable Endoscopic Injection Needle
The disposable endoscopic injection needle is a sterile, single-use device for delivering solutions into the gastrointestinal submucosa and for endoscopic sclerotherapy of varices. It is passed through the working channel of a gastroscope or colonoscope. The needle is advanced out of the sheath by a sliding handle, allowing controlled single-handed puncture at a preset depth; a transparent inner tube lets the operator confirm blood return before injecting.
