A sclerotherapy needle is a specialized medical device used for injecting sclerosing agents into veins or tissues during sclerotherapy procedures. These needles are designed for precision and ease of use in treating conditions such as varicose veins, spider veins, esophageal varices, and gastrointestinal mucosal lesions. Below is a detailed description of its features and applications:
Key Features
Needle Gauge and Length:
Sclerotherapy needles are available in various gauges (e.g., 21G, 23G, 25G) and lengths (e.g., 180 cm, 200 cm, 230 cm), catering to different procedural needs.
Design:
Many needles feature beveled tips for smooth injection and star-shaped inner catheter designs to ensure reliable actuation in complex anatomical pathways.
Some models include pushable sheath constructions to facilitate advancement through tortuous anatomy.
Sterility:
These needles are sterile and intended for single-use only to prevent contamination.
Leakage Prevention:
Advanced designs prevent leakage at the joint between the inner tube and needle, ensuring secure injections1.
