Description

The NEEDLE TUOHY DISP is an essential tool in the field of epidural anesthesia, designed for precise and safe catheter placement. Its unique design features a slightly curved, blunt tip with a lateral opening, known as the Tuohy or Huber point. This design minimizes the risk of dural membrane puncture and allows for accurate directional placement of the catheter.

Key Features

• Anti-Coring Design: Reduces tissue trauma and prevents catheter shearing, enhancing patient safety.
• Depth Measurement: Centimetric graduations along the needle shaft provide clear depth measurement.
• Hub Design: Transparent or color-coded hub for fluid visualization and bevel orientation.
• Handling Control: Removable or fixed wings for improved handling during insertion.

Construction and Materials

• Needle Material: High tensile strength 304 stainless steel.
• Stylet: Made of stainless steel or plastic to prevent tissue coring.
• Thin Wall Construction: Ensures optimal flow during procedures.

Advanced Features

• Echogenic Options: Available for enhanced ultrasound visibility, beneficial in complex cases.
• Back-Eye Opening: Present in some models for combined spinal-epidural procedures.
