Precision Delivery: Luer and Wolf Injection Cannula Needles

 In specialized procedures such as plastic surgery, micro-lipoaspiration, and certain regional anesthesia blocks, controlled fluid delivery or aspiration is required. The Gebogen Luer Cannula Needle (BTCN 0016) and the Wolf Injection Cannula Needle (BTCN 2144) are highly specialized surgical instruments designed for precise fluid management. The Luer cannula features a curved, banded tip for controlled access, while the Wolf cannula is a long, thin needle with a wire, ideal for deep injections over its 350mm length.

These cannulas are characterized by their small diameter (e.g., Luer at 2mm OD) and length, allowing them to navigate tissue planes with minimal trauma. They are crucial for tasks like fat grafting, tumescent fluid infiltration, or injecting solutions into deep tissue. Given the high risk of cross-contamination and the need for absolute sharpness, many modern cannulas are now primarily used as single-use surgical instruments; however, these precision metal cannulas are often designed to be reusable, requiring meticulous sterilization to maintain their fine bore. The precise manufacturing of these reusable tools offers a level of durability and accuracy that exceeds many simpler single-use surgical instruments.

In dentistry, fine-bore needles and cannulas are essential specialized dental instruments for localized anesthesia delivery and for irrigating deep root canals or surgical sites with antimicrobial solutions.

The principle of using long, fine cannulas for injecting or aspirating is a cornerstone of the beauty teck industry. Specialized, non-invasive “surgical instrument” applicators are used for dermal filler injections and micro-needling treatments, ensuring precise and controlled delivery of cosmetic solutions deep into the skin layers.

In conclusion, the Luer and Wolf Injection Cannula Needles are critical surgical instruments for fluid and solution management. Their specialized shapes and fine bores provide the precise control needed for meticulous and safe tissue access and manipulation in advanced medical procedures.
