Quincke Tip：
Quincke Tip Spinal Needles offer superior quality in a broad range of sizes ranging from 18G to 27G, with needle lengths from 2″ to 7″.
Pencil Point:
Plastic fixator wing is available. Standard needle length is 110mm, other needle length is also available. Compared with pencil point, quincke tip causes more damage.
Features:
- Medical grade stainless steel needle and stylets
- Full sizes of anesthesia needle
- Identified as spinal needle bevel quincke tip, pencil point tip and epidural needle
- Needle bevel enables smooth, sharpness, maximize, patient comfort
- Sterile, disposable needles have tinted translucent Luer-Lok hub for better visualization of cerebrospinal fluid.
Usage:
Spinal needles are used to inject analgesia and/or anaesthetic directly into the CSF usually at a point below the second lumbar vertebra. Spinal needles enter the cerebral spinal fluid (CSF) through the membranes surrounding the spinal cord. An introducer needle is used in some cases to stabilise the insertion of the needle and aid insertion through tough skin. The needle and stylet are advanced towards the dura in the intevertebral space (the stylet stops tissue blocking the needle during insertion). An introducer needle is used in some cases to stabilise the insertion of the needle. Once through the dura and in position, the introducer is removed and the removal of the stylet enables CSF to flow into the needle hub. CSF can be collected for diagnostic purposes or a syringe may be connected to the spinal needle to inject anaesthetic agents or chemotherapy agents.
Whilst Quinke needles tend to cut through the dura (the tough outer membrane), pencil point designs such as the Sprotte and Whitacre are designed to part the fibres of the dura rather than cut them, minimising damage to the dura fibres and reducing the risk of post-dural puncture headaches.
