BD Quincke Spinal Needles

This product is a type of spinal needle designed for procedures involving the dura mater, such as spinal anesthesia or diagnostic aspirations. It is constructed from medical-grade stainless steel, ensuring durability and biocompatibility for medical use. The needle features a sharp, precision-engineered tip intended to create a clean puncture, facilitating accurate placement and minimizing tissue trauma.

Each needle is provided in a sterile condition to maintain aseptic technique throughout its use, thereby reducing the risk of post-procedural infections. The design emphasizes ease of use and reliable performance in clinical settings.

The functionality of these spinal needles relies on their specific design for dural puncture. The needle shaft is paired with a stylet that fits snugly within the lumen, preventing tissue coring during insertion. Upon reaching the target depth, the stylet is withdrawn, allowing for the aspiration of cerebrospinal fluid (CSF) or the administration of medications.

A key design element is the translucent needle hub, which provides visual confirmation of CSF return, a critical indicator for correct needle positioning within the subarachnoid space. This visual feedback is essential for the safe and effective administration of spinal anesthesia or other intrathecal therapies.

Several features contribute to the utility and efficacy of these spinal needles. The alignment mechanism between the stylet and the needle cannula, often indicated by a key or slot, ensures that the bevel of the needle is oriented correctly relative to the dural fibers. This orientation is important for minimizing the risk of post-dural puncture headache.

The needles are available in a range of sizes, with diameters from 18 gauge to 25 gauge and lengths extending from 90 mm to 178 mm, accommodating various patient anatomies and procedural requirements. The color-coded hubs, specifically grey in this instance, aid in rapid identification and selection of the appropriate gauge, streamlining the preparation process for medical professionals.

These spinal needles are intended for use by qualified medical professionals, including anesthesiologists, neurologists, and other physicians performing lumbar punctures or administering spinal anesthesia. They are also utilized in hospital settings, surgical centers, and pain management clinics. Patients undergoing procedures requiring intrathecal access, such as surgery requiring general anesthesia or diagnostic tests for neurological conditions, are the recipients of care involving this device.

Caregivers may also be involved in the handling and preparation of these sterile devices under the guidance of medical staff.

Typical applications for these spinal needles include the administration of spinal anesthesia for surgical procedures, the delivery of intrathecal chemotherapy, diagnostic aspiration of cerebrospinal fluid for laboratory analysis, and the management of certain chronic pain conditions through intrathecal medication delivery. They are also employed in diagnostic procedures to assess for conditions affecting the central nervous system that can be diagnosed through CSF analysis. The precise nature of the needle tip and the availability of various sizes allow for tailored application based on the specific clinical indication and patient characteristics.

Important usage notes include the fact that these needles are designed for single use only and must not be resterilized or reused. Reusing a single-use device carries a significant risk of infection and compromised performance. The packaging should be inspected for integrity prior to use; any damage to the sterile barrier should result in the rejection of the product.

Storage should be in a cool, dry environment, away from direct sunlight, to maintain sterility and material integrity. Devices should be kept out of reach of children. Proper disposal protocols for medical waste must be followed after use.
