摘要

Biopsy device with probe substituu00ecvel that incorporates recovery of stacking and rinse samples of saline solution of double valve of the vacuum source static. The present invention relates to a device and method for obtaining a biopsy tissue sample, such as a sample of tissue biopsy of the breast.The device includes a set of disposable biopsy probe with an external cannula which has a spike more distant, a cutter lumen, and a tube cutter which rotates and transfers through a lateral opening in the outer cannula to cut a tissue sample.The device also includes a reusable biopsy handpiece with a motor and a power source integral to make a control convenient, independent for use with the formation of ultrasonic image. The reusable handpiece incorporates a mode of oscillation of the probe to assist when inserting the protruding bridge furthest in the tissue.A valve positioned by the reusable handpiece saline communicates with a supply of saline solution through a series of probe to perform a rinsing of saline solution of the tube cutter and outer cannula.
