The invention relates to a
biopsy puncture auxiliary locator. The
biopsy puncture auxiliary locator is characterized by comprising base plates which are matched with each other, a fixing plate, a locating pin reference plate, a rotating arm, a rotating sliding block, a sliding block gland and a guide
pipe. The locating pin reference plate is arranged on the fixing plate, the base plates are magnetically connected to the locating pin reference plate, the rotating arm can rotate around the base plates, and the guide
pipe is matched with the rotating sliding block and the sliding block gland and arranged on the rotating arm in a sliding mode. According to the
biopsy puncture auxiliary locator, a doctor can perform a puncture operation fast and accurately, accuracy and stability are high, CT scanning is not needed again even if the
body position of a patient moves inadvertently after location is finished, the locating position can be recovered just by overlapping an
infrared reference line on the biopsy puncture auxiliary locator and CT
infrared rays, repeated CT scanning and progressive
needle insertion of a traditional puncture operation are avoided,
operation safety is improved,
operation time is shortened,
radiation exposure caused by repeated roentgenoscopy is reduced, and
tissue trauma and complications are reduced.
