User interface on biopsy device

摘要

A biopsy device (100,101) includes a probe (102,103) and holster (202,302) that may be coupled together. The probe includes a cannula (12) with a transverse opening (16) and a cutter (50) within the cannula. The holster includes a mechanism (120) that is operable to rotate and translate the cutter within the cannula. In one example, the holster also includes a user interface (800) having buttons (802,803,804,806,808) and indicators (810,814,816,820). The indicators may indicate, e.g., the longitudinal position of the cutter within the cannula and an error condition. The buttons may be operable to, e.g., selectively and incrementally adjust the longitudinal position of the cutter within the cannula, initiate a sampling cycle, initiate a clear probe cycle, and initiate a lateral vacuum cycle. The user interface may also include a trigger (242) operable to cock and fire the cannula into tissue. The user interface may be provided as one or more membranes on one or more sidewalls of the holster.
