|Title:||AUTOMATED TISSUE DISSECTION INSTRUMENT AND METHODS OF USING THE SAME|
A system, an instrument, a computer-implemented method, and a clinical workflow for mesodissection of biological specimens on tissue slides by incorporating annotations. An image of an annotated reference slide is acquired and transposed onto a plurality of serial samples on the tissue slides along with the corresponding annotations and metadata. The serial samples are milled based on the annotations, and the milled tissue is automatically collected along with a milling buffer solution inside milling tips, and then dispensed in designated collection vials. The instrument automates the filling of aqueous buffer inside the milling tips and the monitoring of the buffer solution and the sequential filling of the milling tips. The workflow provides an integrated interface that performs tissue annotation, alignment, dissection, tracking, and reporting on a single screen. The degree of precision, ease of use and repeatability will improve PCR and NGS test results, ultimately providing timely patient results.
