Breast Localization Wire & Guide Needle Basic information Localization wire (wire) and marker clip (clip) are implantable positioning devices that can be used to locate primary breast lesions and axillary lymph metastases through image-guided percutaneous puncture. Clinical studies It is an important tool for accurate functional breast surgery [1-4]. Benefits By using breast tissue positioning guide wire and positioning marker clip to accurately locate breast and axillary lesions, the target lesions can be completely removed, and the damage to surrounding normal tissues can be reduced on the basis of ensuring tumor safety [1 -4], Designed to lock securely while being able to reposition after placement [1] Kapoor MM, Patel MM, Scoggins ME.

The back of the positioning guide wire pre-installed in the guide needle has two release indication markers to indicate the position of the wire tip relative to the needle. The first release indicator mark for the localization wire is located outside the guide needle handle, indicating that the "Q/double J" shape of the localization wire is completely inside the piercing needle. As the positioning localization wire gradually enters the guide needle, the first release indicator mark enters the guide needle handle, and the shape of the localization guide wire begins to unfold. The localization...
