Coaxial needle
Safe & effective needle placement for hard-to-reach targets
Gangi-HydroGuard® combines the well-known technique of a coaxial biopsy needle with an all new spring loaded blunt tip stylet providing more control during soft tissue biopsy.
The spring loaded blunt tip stylet:
- Enables penetration without removal of the blunt needle
- Provides visual and tactile feedback
Blunt tip:
- Coaxial blunt tip stylet helps reduce the risk of damage to vasculature or other organs
Coaxial biopsy needle:
- Provides the ability to cut through tissue
- Centimeter markings on needle for easy depth evaluation
- Echogenic marking on cannula allow for precise ultrasound placement
