An Initial Puncture Needle is a sharp, hollow surgical needle used to make the first access into the body during minimally invasive procedures such as laparoscopy, nephrostomy, or catheter insertion. It helps in establishing a safe and controlled entry path for guidewires, catheters, or other instruments.
Key Features of an Initial Puncture Needle:
Sharp Beveled Tip
Ensures smooth and precise penetration through skin and tissue.
Hollow Lumen
Allows insertion of guidewires or fluid aspiration once access is gained.
Radiopaque Markings
Visible under X-ray or fluoroscopy for accurate placement.
Different Gauge Sizes
Available in various diameters and lengths to suit different procedures.
Ergonomic Grip
Designed for stability and control during puncture.
Sterile & Disposable
Single-use design reduces infection risk and maintains procedural hygiene.
Common Applications:
Percutaneous nephrostomy (kidney drainage)
Central venous catheter insertion
Laparoscopic entry
Fluid aspiration or drainage
