Key Benefits
The Modified Tuohy point improves tissue navigation while reducing the risk of unintended dural puncture compared to sharper bevels. Fixed wings allow secure grip and fingertip control, supporting smooth needle advancement and precise depth adjustments. The 17G diameter provides optimal rigidity and tactile sensitivity, helping clinicians identify anatomical layers with confidence. The 5" length accommodates deeper needle paths without compromising maneuverability. As a sterile, single-use needle, it supports infection control and consistent procedural reliability.
Compatibility and Applications
The BD 405193 Weiss Needle is compatible with standard epidural syringes, loss-of-resistance syringes, and accessory components commonly used in neuraxial anesthesia. It is ideal for epidural placements, combined spinal-epidural techniques (with appropriate equipment), regional blocks requiring directional needle control, and certain interventional pain procedures. It is widely used in obstetric anesthesia, orthopedic surgery, general surgery, and chronic pain clinics.
Usage Guidelines
Prepare the procedural field using full aseptic technique. Hold the needle by the fixed wings to guide insertion with controlled, stable hand positioning. Advance incrementally, monitoring for tissue resistance changes and confirming placement per institutional protocol. Attach compatible syringes securely to the hub for LOR or aspiration testing. Dispose of the needle immediately after use in accordance with sharps safety regulations.
Certifications, Safety Standards, and Regulatory Approvals
This needle is manufactured under BDs strict quality assurance processes and complies with applicable ISO standards for neuraxial access devices. The needle design supports safe, precise insertion while meeting regulatory requirements for sterile, single-use medical needles. All materials and components adhere to safety and performance standards essential for anesthesia procedures.
Comparison with Competitor Products
Compared to generic Tuohy-style needles, the BD 405193 offers superior bevel engineering, smoother tissue navigation, and enhanced stability through its fixed-wing design. Many competitors lack the ergonomic wing configuration or the refined Modified Tuohy tip that provides BDs reliable balance of penetration control and safety. BDs high-precision manufacturing ensures consistent needle sharpness, lumen integrity, and tactile performance.
Typical User Profile and Application Scenarios
This product is used primarily by anesthesiologists, CRNAs, pain management physicians, and regional anesthesia specialists. It is ideal for epidural catheter placement, regional analgesia, CSE techniques (when used with compatible spinal needles), and interventional procedures requiring deep or controlled needle advancement.
Best Practices for Use and Maintenance
Verify needle gauge, length, and integrity before opening. Maintain a steady grip on the fixed wings to avoid rotational drift during insertion. Follow institutional protocols for identifying the epidural space or verifying placement. Avoid excessive force to prevent tissue trauma. Always dispose of the needle in an approved sharps container immediately after single use.
Regulatory and Safety Information
The BD 405193 Weiss Needle complies with sterile single-use medical device regulations, OSHA sharps safety requirements, and neuraxial anesthesia guidelines. It must only be used by trained clinical professionals and must not be reused or reprocessed. Handle and dispose of safely according to facility policy.
