Intro is a coaxial introducer needle used as insertion guide for cannulas, biopsy devices, catheters, breast localization wires, and other devices.
The device allows multiple procedures to be executed simultaneously in the patient by leaving the introducer needle in the body while the biopsy needle is unloaded and reloaded.
Intro is supplied with a trocar-tipped stylet designed to penetrate tissue with minimal patient pain. The universal luer lock and handle are made with transparent plastic to allow fluid visibility. Centimeter markings and a sliding stopper enhance determination of insertion depth.
Coaxial needles have many advantages such as:
faster cannula advancement through hard tissues by avoiding friction of parenchymal tissues
ability to perform multiple biopsies
easier and more precise location of biopsy site due to echogenic markers
