A nerve stimulator needle is a nerve block needle that can be used with a nerve stimulator. In a peripheral nerve block it connects to an external stimulator, and the muscle the nerve supplies responds as the tip nears the nerve. It is not an implanted stimulator. The needle is 22G, in 50, 80, 100 and 120 mm.

Nerve block needles that can be used with a nerve stimulator, in 22G and in 50, 80, 100 and 120 mm, as a nerve stimulation and an ultrasound nerve stimulation series.
A nerve stimulator needle is a nerve block needle that can be used with a nerve stimulator. In a peripheral nerve block it connects to an external stimulator. Stimulators implanted at the spinal cord, the vagus nerve or the sacral nerves are different devices, and this page describes only the needle.
A nerve stimulator needle connects to a nerve stimulator and delivers current at its tip. When the tip nears the nerve, the muscle the nerve supplies responds, and the response shows that the tip is near the nerve. An ordinary block needle delivers no current. The needle on this page has a pinpoint discharge structure at the tip and an ultra-thin transparent nano coating.
The two techniques complement each other and are also used together. A Cochrane review of 32 trials in 2844 adults found that ultrasound guidance, alone or with a stimulator, increased block success compared with a stimulator alone. Using both lengthened the procedure time. The physician decides on the technique.
22G in 50, 80, 100 and 120 mm. The same four lengths are made as a nerve stimulation needle (NSN) and as an ultrasound nerve stimulation needle (UNSN).
The price depends on the length, the series (NSN or UNSN) and the quantity. We do not publish a list price on this page. Write to us and we will prepare a quote.
