• Model: 4792.803
• Gauge: 18G
• Overall Length: 150mm

The Richard Wolf 4792.803 Puncture Needle Set (18G, WL 150 mm) is a precision instrument designed for percutaneous access in spinal procedures, especially those following the Vertebris lumbar / interlaminar approach. The 150 mm working length is well suited to reach epidural or intradiscal spaces from percutaneous entry sites in lumbar anatomy. The 18 gauge (≈ 1.25 mm outer diameter) offers a balance between minimizing tissue trauma and providing sufficient rigidity and lumen size for guidewire or tool passage.

Clinically, the set is used during the initial access phase of minimally invasive spinal surgeries, where controlled passage through soft tissues and bony access corridors is needed. The sterile, disposable nature ensures consistent sharpness of the puncture tip and eliminates concerns about reuse or reprocessing damage. Because it comes in packs of 10, clinicians have backups on hand and can maintain a sterile inventory for multi-case scheduling.

In use, the puncture needle guides the initial path of entry before dilators, working sleeves, or sheaths are introduced. The needle’s small diameter and optimized length help reduce soft tissue drag and resistance. Once proper placement is confirmed (often via imaging guidance), the cannula (or dilator) sequence proceeds. The 4792.803’s design supports safe, accurate targeting in spinal endoscopic or percutaneous decompression, discectomy, or instrumentation workflows.
