Swaged Needles: Definition, Merkmale und klinische Anwendungen

Swaged Needle Overview

A swaged needle features a precision-cut, smooth end formed by cutting and finishing metal tubing—rather than a sharpened bevel. These needles are typically blunt or hollow.

Clinical Applications

• Specialized injections (e.g., intravitreal, intrathecal)
• Aspiration procedures (bone marrow, joint fluid)
• Biopsy needles (core, fine-needle)
• Micro-dosing or catheter-over-needle systems

Key Features

• Requires dedicated holder/device
• Reduces tissue trauma compared to beveled needles in certain contexts
• Sterile, single-use

Used in ophthalmology, interventional radiology, and minimally invasive surgery.
