摘要
A method for percutaneous excisional breast biopsy and a percutaneous excisional breast biopsy device (PEBB device). In one variation of the method, the following steps are conducted: locating a breast lesion by radiographic techniques; positioning and implanting a localizing needle distal to said breast lesion, said localizing needle containing a hooked guide wire; positioning and implanting said hooked guide wire distal to said breast lesion; making a small incision on the surface of the breast at the point where said localizing needle enters the breast; passing a PEBB device over said localizing needle; inserting said PEBB device through said incision; further inserting said PEBB device and pushing aside the breast tissue; positioning said PEBB device to the desired location proximate said lesion; further inserting into the breast a first cutting surface of said PEBB device to the desired location distant said lesion; manipulating a second cutting surface of said PEBB device and cutting the portion of the breast tissue distal to said hooked guide wire to separate a portion of said breast tissue containing all of said lesion; and removing the PEBB device containing said lesion.
