Mammary gland puncture biopsy auxiliary base plate

The invention relates to a mammary gland puncture biopsy auxiliary base plate, the auxiliary base plate comprises an auxiliary backing plate body, the auxiliary backing plate body is made of a macromolecule impurity-free transparent material, a hollowed-out puncture area is arranged at the position, close to the edge, of a longitudinal center shaft of the auxiliary backing plate body, and the hollowed-out puncture area is of a through hollowed-out structure; one face of the auxiliary base plate is provided with an extending part used for increasing the distance from the upper end face to the lower end face of the extending part. The extension part is designed for increasing the distance from the upper end face of the auxiliary base plate to the lower end face of the extension part, and meanwhile the adsorption piece is fixedly attached to a mammary gland molybdenum target drone; the puncture thickness of a disposable biopsy puncture needle in mammary gland puncture biopsy is increased,the problem that equipme
