How the Disposable Endoscopic Needle Works
An 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.
Transparent Inner Tube
Can be used to observe blood return.
Strong PTFE Sheath Construction
Facilitates advancement through difficult pathways.
Needle Tip Angel 30 Degree
Sharp puncture
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.
Ergonomic Handle Design
Easy to control the needle moving.
Frequently Asked Questions (FAQ)
What are the primary clinical indications for this endoscopic injection needle?
The device is mainly used to inject fluid to elevate mucosal lesions away from the muscularis propria during endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD), as well as for endoscopic hemostasis and hemorrhage control in gastroenterology, colonoscopy, and upper endoscopy procedures.
What needle gauges and lengths are available?
The needles are available in gauge sizes 21G, 23G, and 25G, with projection needle lengths of 4 mm and 6 mm. The overall working catheter lengths include 1800 mm (typically for upper GI endoscopy) and 2300 mm (typically for colonoscopy).
What endoscope channel size is required to use these needles?
All models have an outer sheath diameter of Φ2.4 mm and require an endoscopic working instrument channel of ≥ 2.8 mm.
What are the benefits of the PTFE sheath construction?
The strong PTFE outer sheath provides optimal pushability and low-friction maneuverability, facilitating smooth advancement through tortuous anatomical pathways and retroflexed endoscopes.
How does the transparent inner tube assist the physician during procedures?
The transparent inner lumen allows the clinical team to visually observe blood return immediately upon aspiration, verifying intravascular or extravascular positioning.
Why is a 30-degree bevel angle utilized on the needle tip?
The precision-ground 30-degree bevel angle ensures sharp puncture performance with minimal tissue trauma and reduced penetration force when accessing target submucosal areas.
