Orthopaedic coaxial injection applicator

Orthopaedic coaxial injection applicators are surgical tools designed to deliver therapeutic substances—such as biologics, bone fillers, or irrigation fluids—directly into bone during minimally invasive procedures. Positioned over a guidewire, these devices use a dual-lumen design to guide the guidewire internally while allowing precise fluid injection through an outer lumen, often assisted by a plunger.

These devices are typically single-use, constructed from metals or polymers, and regulated as surgical instruments. They are used in orthopaedic surgeries to enhance precision in bone treatment, but their classification and supply vary by jurisdiction and specific application.
