Final answer:
The Pereyra needle is used in bone marrow sampling or transplant surgery.
Step-by-step explanation:
The Pereyra needle is used in the specialty area of bone marrow sampling or transplant surgery. In the past, this procedure would have required inserting a large-bore needle into the region near the iliac crest of the pelvic bones. The Pereyra needle is specifically designed for this purpose, as it allows for relatively easy access to the bone marrow while minimizing pain and risk to vital organs.
