The tip is the decision that matters most; gauge and length follow:
| Needle type | Gauge | Length | Tip / feature | Primary use |
|---|---|---|---|---|
| Spinal, pencil-point | 25G / 26G / 27G | 90 / 103 / 120 mm | Atraumatic (Whitacre-type) | Low-headache spinal, obstetrics |
| Spinal, Quincke | 22G / 25G / 26G | 90 / 103 mm | Cutting bevel, stylet | Spinal with fast CSF flash |
| Epidural, Tuohy | 16G / 18G | 80 / 100 mm | Curved bevel, depth marks | Epidural catheter placement |
| CSE spinal needle | 27G | Matched to Tuohy | Length-matched to set | Single-puncture CSE |
| Nerve block needle | 21G / 22G | 50 / 80 / 100 / 150 mm | Short or facet bevel, insulated option | Peripheral and plexus block |
| Lumbar puncture needle | 22G / 25G | 90 / 120 mm | Atraumatic tip | Diagnostic lumbar puncture |
Note: gauges and lengths shown are the configurations we produce most. Hub type, stylet format and depth marking are confirmed on the drawing before production.
Needle performance is judged over hundreds of insertions, so consistency is the whole product:
A pencil-point (atraumatic) tip has a closed, rounded end with a lateral eye. It separates dural fibres rather than cutting them, and is associated with a lower incidence of post-dural-puncture headache — this is why it is the usual choice for obstetric and younger patients. A Quincke needle has an open, cutting bevel that penetrates more sharply and often gives a faster cerebrospinal fluid flash, which some practitioners prefer for insertion speed and feel. Both are widely used; the choice is a departmental protocol decision.
Headache incidence falls as needle diameter decreases, so 27G pencil-point needles show the lowest rates of the atraumatic designs, followed by 26G and 25G. The trade-off is that finer needles return cerebrospinal fluid more slowly and feel more flexible during insertion, which extends procedure time slightly. Many departments therefore standardise on 25G–26G pencil-point as a balance, reserving 27G for patients at highest headache risk.
18G Tuohy is the more common general-purpose epidural needle: adequate for catheter passage with less tissue trauma and a lower incidence of accidental dural puncture than a larger gauge. 16G is selected where a larger-bore or multi-orifice catheter is used, or where departmental protocol calls for it. Both are supplied with centimetre depth markings and a matched stylet, and both accept standard epidural catheters.
90 mm is sufficient for most adults, but depth to the subarachnoid space varies with body habitus and the intended interspace, and a longer needle (103–120 mm) is needed when the space is deep. Measuring rather than estimating from body weight is the reliable approach. For safety, longer needles are used with the depth marked and the stylet in place until the space is reached.
Yes. Block needles are available with an insulated shaft and a hub connection for nerve stimulation, in 21G–22G and lengths from 50 mm to 150 mm, with short or facet bevel tips. Plain (non-insulated) block needles are also supplied for ultrasound-guided techniques where needle visualisation rather than nerve response guides placement.
Yes. Needles are supplied loose, in bulk, or as a component of a configured procedure kit. Distributors who assemble their own packs generally take them loose with their own sterilisation and packaging step; distributors who ship finished packs take them assembled. Traceability documentation is provided either way.
