Publication number: 20090131821Abstract: A biopsy system includes a vacuum control module, a cannula with a transverse opening, a cutter within the cannula, and a rotatable tissue sample holder. The vacuum control module includes a speaker, a vacuum source, and a graphical user interface for controlling the biopsy system. The graphical user interface includes a display and capacitive switches that serve as buttons. The graphical user interface is operable to perform, e.g., the following functions: varying the position of the cutter relative to the transverse opening, activating a view sample mode, resetting the position of the rotatable tissue sample holder, activating a maintenance vacuum pulse mode, varying the level of vacuum provided by the source of vacuum, varying the level of volume of sounds emitted by the speaker, selectively placing the biopsy system in a standby mode, and selectively shutting the biopsy system down.Type: ApplicationFiled: November 20, 2007Publication date: May 21, 2009Inventors: Trevor W.V.
