Description

The Tuohy needle, commonly referred to as the Huber Point Needle, is an essential tool in the administration of epidural anesthesia. Its primary function is to facilitate the precise insertion of epidural catheters, ensuring safe and effective access to the epidural space for both single-shot and continuous drug delivery.

Key Features

• Curved, Non-Coring Tip: The needle's transversely curved tip is designed to minimize tissue trauma and prevent puncturing the dural membrane. This feature, along with the lateral orifice, allows the catheter to exit at a 45-degree angle, enhancing directional placement.

• High-Quality Materials: Constructed from high tensile strength 304 stainless steel, the needle offers durability and reliability. The accompanying stylet, made from either stainless steel or plastic, reduces the risk of skin plugging and tissue coring.

• Color-Coded Hub: The polypropylene hub, which may be transparent or color-coded, aids in visualizing fluid reflux and provides easy tip orientation. Options for Luer type or Petals type hubs are available.

Design and Usability

• Graduations and Markings: The needle features centimetric or 10 mm interval markings, starting at 3 cm, to enhance depth awareness during insertion.

• Removable or Fixed Wings: Some models include wings to facilitate easier handling and control during insertion.

• Bevel Heel Design: A smoothed or buffed bevel heel reduces the risk of catheter shearing, ensuring safer use.

Sterility and Packaging

• Disposable and Sterile: Each needle is single-use, sterile, pyrogen-free, latex-free, and contains no animal products. Sterilization is achieved through ethylene oxide (EO).

• Individual Packaging: Needles are individually packaged and available in various configurations, including bulk options.

Size and Configuration

Available in gauges ranging from 16G to 25G and standard lengths of 80 mm to 90 mm, with longer versions up to 15 cm for specific patient needs. Special configurations, such as extra-long needles and back-eye openings, cater to diverse clinical requirements.

Common Applications

Ideal for use in obstetrical, surgical, and pain management settings, the Tuohy needle supports catheter-based repeated epidural injections, intrathecal drug delivery, and more. Its design ensures high-quality performance, reducing complications and enhancing catheter guidance.

Professional Use and Handling

Intended for professional use by trained personnel, the needle should be stored in a cool, dry, dust-free environment and disposed of according to medical waste regulations after use.

Certifications and Quality

Adhering to certifications such as CE, ISO 9001:2015, ISO 13485, and FDA 510K, the needle undergoes precision manufacturing and rigorous quality control. Techniques like grinding, swaging, bending, laser marking, and electropolishing ensure a smooth internal edge and accurate placement, with tolerances maintained at +/-0.01 mm.
