PENFIELD DURA DISSECTORS FIG.1 17,5 CM

The Penfield Dura Dissector, Figure 1, measuring 17.5 cm (centimeters), is a specialized surgical instrument primarily used in neurosurgical procedures for dissecting and separating delicate tissues, particularly the dura mater, which is the tough outer membrane covering the brain and spinal cord.

  1. Size and Shape: The Penfield Dura Dissector typically measures 17.5 cm in length. It features a slender, elongated shaft with a curved or angled tip, allowing for precise manipulation and dissection of tissues in neurosurgical procedures.
  2. Material: It is usually made of high-quality surgical-grade stainless steel or other biocompatible materials to ensure durability, corrosion resistance, and compatibility with sterilization procedures.
  3. Design: The Penfield Dura Dissector is characterized by its specialized design, featuring a slender, tapered tip with a fine, delicate profile. The tip may be curved or angled to facilitate access to hard-to-reach areas and ensure optimal visibility during dissection. The instrument may also feature a textured or serrated surface to provide a secure grip on tissues and enhance precision during surgical maneuvers.
  4. Usage: The primary function of the Penfield Dura Dissector is to gently dissect and separate the dura mater and other delicate tissues during neurosurgical procedures, such as craniotomies, laminectomies, and spinal cord surgeries. It is commonly used to create a surgical plane and expose the underlying structures, allowing the neurosurgeon to access and treat the pathology with minimal trauma to surrounding tissues.
  5. Sterilization: Like all surgical instruments, the Penfield Dura Dissector undergoes thorough sterilization before each use to prevent infection and ensure patient safety. Sterilization methods may include autoclaving, chemical disinfection, or ethylene oxide gas sterilization.
