Retractor Hook

Retractor hook (also known as a surgical hook retractor) is a handheld or self-retaining surgical instrument used to hold back soft tissue, muscle, skin, or organs to provide better exposure of the surgical field.

  • To retract tissue or anatomical structures during surgical procedures.
  • Allows the surgeon unobstructed visualization and access to the target area.
  • Reduces the need for manual retraction by assistants.

By Design

  • Sharp hook: Penetrates fascia or muscle. Used in spinal, orthopedic, or neurosurgical exposure.
  • Blunt hook: Retracts softer structures without trauma (e.g., vessels or nerves).
  • Skin hook: Fine and delicate, used in plastic or ophthalmic surgery.

By Configuration

  • Handheld: Requires manual control by assistant or surgeon.
  • Self-retaining: Mounted or attached to retraction systems (e.g., Leyla arm, Greenberg system).
  • Cushing hook
  • Cloward hook
  • Hohmann retractor (with hook tip)
  • Adson hook
  • Miyake nerve hook
  • Neurosurgery: Retraction of dura, nerve roots, brain parenchyma.
  • Orthopedic surgery: Exposure of joints, bones, and ligaments.
  • ENT and plastic surgery: Fine tissue handling with minimal trauma.
  • Spinal surgery: Retraction of paraspinal muscles, lamina, or dura.
  • Must avoid excessive pressure to prevent tissue ischemia or nerve damage.
  • Sharp hooks must be used carefully to prevent accidental puncture.
  • Always assess anatomical relationships before placement.
  • Should be cleaned and inspected regularly to maintain sharpness and integrity.
