Description

Technical Field

[0001] The utility model specifically relates to the technical field of medical auxiliary equipment, and in particular is a magnetic resonance compatible breast puncture positioning auxiliary device. Background Art

[0002] Breast tumor is the most common tumor in women, and dense breast is more common in Asian women, which leads to unclear tumor display under ultrasound and phase target, affecting the location and characterization of the tumor. Magnetic resonance imaging has obvious advantages in the diagnosis of breast tumors. The traditional treatment of breast tumors is large-scale surgical resection supplemented with radiotherapy and chemotherapy, which causes great physical and mental harm to patients. Small-scale quadrant resection is increasingly accepted by the medical community in the treatment of early breast cancer, but the tumor location must be accurately located before surgery.

[0003] Currently, preoperative localization and puncture of non-palpable breast masses are mainly guided by ultrasound and molybdenum targets. However, some masses are not clearly displayed under ultrasound and molybdenum targets. Magnetic resonance imaging is the best for displaying soft tissue tumors such as breast masses. Preoperative enhanced MRI can help locate breast masses or perform puncture biopsy, which is helpful for further breast-conserving surgery. Utility Model Content
