An assembly of mains electricity (AC-powered) software-based devices designed to be used in the laboratory for the automated, or remotely-controlled, computer-aided dissection of microscope-slide-mounted tissue specimens under digital image guidance, allowing the user to digitally preselect the target dissection area with high precision. It consists of a high-resolution magnification unit, a robotic arm with an attached disposable milling tip, a remote control unit, and a display screen; excised tissues are suctioned into a sample tube for subsequent histopathology analysis.
