A needle system with a retractable barb was developed for localization of nonpalpable breast lesions. The system can be repositioned without major adjustments and strongly anchors to breast tissue, eliminating failure due to dislodgment or transection of the localizing wire. Its use may necessitate fewer confirmatory radiographs, resulting in decreased radiation exposure. In addition, the needle can be retracted during surgery, to ease extraction of the specimen.
一种带有可回缩倒刺的针系统被研发出来用于不可触及乳腺病变的定位。该系统无需进行重大调整即可重新定位，并能牢固地锚定在乳腺组织中，消除了因定位线移位或切断而导致的失败情况。使用该系统可能需要更少的确认性X光片，从而减少辐射暴露。此外，在手术过程中针可以回缩，以便于标本的取出。
