The SNARECOIL needle is a specimen capturing bone marrow biopsy needle that incorporates a tiny internal capturing coil. It was developed to minimize postinsertion needle manipulation and to facilitate specimen recovery. Forty-four patients underwent 50 bone marrow biopsy procedures with the SNARECOIL needle for a variety of hematologic indications. Second and third procedures were done for follow-up or staging. Each procedure retrieved a specimen with an average length of 2.1 cm. Fifty-two percent of the specimens were > or =2.0 cm in length. The majority of specimens demonstrated intact marrow architecture enabling a pathologic diagnosis in every case. Delicate cores of nontrabeculated marrow were recovered in three cases. The SNARECOIL bone marrow biopsy needle reliably retrieves intact bone marrow core specimens for pathologic interpretation.
SNARECOIL针是一种带有微小内部捕获线圈的标本采集骨髓活检针。它的研发目的是尽量减少穿刺后对针的操作，并便于标本回收。44例患者因各种血液学指征使用SNARECOIL针进行了50次骨髓活检操作。第二次和第三次操作是为了随访或分期。每次操作回收的标本平均长度为2.1厘米。52%的标本长度≥2.0厘米。大多数标本显示骨髓结构完整，每例均能做出病理诊断。3例回收了非小梁化骨髓的精细核心。SNARECOIL骨髓活检针能可靠地回收完整的骨髓核心标本用于病理解读。
