Abstract

This invention discloses a breast biopsy positioning device, comprising a bed board, a lifting mechanism, a housing, a positioning rod, a clamping device, and a drive mechanism. The housing is detachably mounted on the lifting mechanism, which drives the housing to move up and down perpendicularly to the bed board. The housing is hemispherical and annular, with its bottom opening facing the bed board. The housing includes multiple polygonal interlocking blocks, which are transparent. These interlocking blocks are detachably and sealed together to form the hemispherical housing. Each interlocking block has radially protruding holes penetrating its inner and outer surfaces, and a positioning rod is slidably inserted into each hole. Each interlocking block contains a clamping device. The drive mechanism is connected to all the clamping devices and drives all the clamping devices to simultaneously clamp and fix their corresponding positioning rods. This breast biopsy positioning device can perform puncture and positioning of the breast while reducing pressure on the breast and improving breast comfort.
