Appendectomy ex-vivo demonstrations (logger, endoscope, force, labels)
585 recorded episodes (2026-07-12), rabbit cadaver appendix in a laparoscopic phantom, hand-held instruments carrying the ex-vivo instrument-state logger. Folders: MCU (left grasper, right cutter), Blackmagic (endoscope 4K60), Camera (overhead webcam), NI6009 (strain-gauge force), labels (hand-corrected phase segments).
Part of the data release for the ICRA 2027 submission From Instrument-Mounted Demonstrations to In-Vivo Execution (double-anonymous review). File formats and known issues are documented on the companion page linked from the paper.
