摘要

A biopsy device includes a body, a needle, a hollow cutter, a vacuum pump, and a tissue sample holder. The needle extends distally from the body. The hollow cutter is movable relative to the needle to sever a tissue sample. The vacuum pump is carried by the body. The tissue sample holder is supported on the body and disposed proximally of the needle and receives tissue samples severed by the cutter. The tissue sample holder is in fluid communication with the vacuum pump and an external source of vacuum.
