Performing a Biopsy
When all of the preparatory steps are complete, and you have recently verified the
alignment (see Verifying the Alignment on page 224), perform the biopsy on the patient.
Note the following warnings that pertain to the biopsy procedure.
Performing a biopsy requires that you understand:
• Assembling the Bracket and Guide on page 222
• Biopsy Procedure on page 222
Warning: Ensure the accessories for a transducer are properly cleaned,
sterilized, or disinfected as appropriate before each use to avoid
possible patient contamination.
Warning: For needle guides in sterile packaging:
The needle guide is packaged sterile and is a single-use item. Do
not use if the packaging indicates signs of tampering or if the
expiration date has passed.
Warning: For needle guides not in sterile packaging:
Needle Guide Bracket kits are packaged non-sterile. Sterilize
these products prior to their first use.
Warning: If a needle guide becomes contaminated with tissue or fluids of a
patient known to have Creutzfeld-Jacob disease, then the needle
guide should be destroyed. Sterilization is not effective against
Creutzfeld-Jacob contamination
Warning: For each procedure, use a straight, new needle. Using a bent
needle, or re-using a needle, can injure or infect the patient.
If the needle does not follow the expected path, discontinue the
biopsy and contact a Terason representative.
The biopsy guide lines indicate only the expected path of the
needle. Verify the actual needle position by identifying the echoes
from the needle.
Note: If the needle strays outside of the guide lines, no warning displays.
