title: [The development of a guide device for stereotactic core-needle biopsy of the breast].
abstract: To meet the need of accurate positioning for biopsy gun in the breast biopsy operation, a new stereotactic biopsy guide device have been developed to adapt to the domestic mammary machine, which can help physician to carry out biopsy operation more accurately and effectively. The guide device has the motion model, measurement model and display model and can realize linear motion and display real-time displacement values in X, Y and Z direction. The experimental results showed that the guide device could be well fixed in the domestic mammary machine, and achieved good accuracy and repeatability in each direction. Depending on the displacement values, physician can change the space of biopsy gun accurately.
