Instructions for Using The Cook Bx Device And Needle

  1. Inspect the product package for damage. If undamaged, open the package using proper aseptic technique.
  2. Remove the needle from the pouch. Inspect the stylet for damage to the point, the cannula for damage to the cutting edge, and check for other imperfections that would prevent the proper operation of the needle assembly.
  3. Open the lid of the biopsy device, load needle set into the biopsy device, close lid, and remove protective sheath.
  4. Safety button must be set in the unlocked (right) position before cocking.
  5. Cock the actuator handle twice to activate the device for firing (this automatically sets the safety.)
  6. Release the safety by pushing the Safety Release Button located on the side of the device.
  7. Firing the device can be achieved by pushing in on either the front trigger button or the rear trigger button . This action will trigger the spring mechanism, propelling the needle forward for a core biopsy sample.
  8. The needle need not be removed from the biopsy device to retrieve the sample.
  9. After removing the needle from the patient, reset safety button and cock the actuator handle once to expose the biopsy notch located at the distal end of the needle. This action exposes the specimen for removal. Cocking the actuator handle a second time will activate the device for a second biopsy.
