"Engraving" is a processing method to carve extremely fine grooves on the surface of needle tube. On our Nerve Blockade Needle, two fine spirals are carved crossing each other, condensed within approximately 15mm from the tip of the needle. The reflection of ultra sonic wave from this groove will be clearly recognizable as white shadow on the screen of the imaging device, and support safe puncture.
Short Bevel
The Nerve Blockade Needle seeks both sharpness and moderate puncture resistance. Unisis' Nerve Blockade Needle has characteristic 30°bevel angle with Back-Cut processing, which enables fine clicking sense at plexus and straight advancing performance.
