Blank cells: measurements awaited from the manufacturer.

Spinal, epidural and combined spinal epidural needles ordered as single items: pencil-point or Quincke spinal needles in 20G to 27G, Tuohy epidural needles in 16G to 19G.

In which cases?

A pencil-point spinal needle in obstetric anesthesia.
A Tuohy needle for an epidural catheter in postoperative pain management.
A combined spinal epidural, where the block starts fast and the catheter carries the rest.

What makes it different?

The spinal needle rotates freely in its hub through a full turn and locks in the chosen position, so the injection direction is set.
Pencil-point and Quincke bevels are both made, so the tip is a choice and not what the box happens to hold.
The epidural needle carries depth marks on the shaft and its wings can be removed.
On the combined needle a twist lock holds the spinal needle so it does not move while the drug goes in.

Frequently asked questions

Which gauges and lengths are supplied?

The spinal needle in 20G, 22G, 25G, 26G and 27G at lengths of 40 to 200 mm, the Tuohy epidural needle in 16G, 17G, 18G and 19G at 65 to 135 mm, and the combined needle in 16G/25G and 18G/27G.

Can the bevel of the spinal needle be chosen?

Yes. The pencil-point and the Quincke bevel are both made, so the tip is picked at the order. The spinal needle also turns freely in its hub through a full turn and locks in the chosen position.
