Have you got?
This is a common question across the civilised world of surgery. Needless to say, that surgeon’s favourite bit of kit has either never been seen before, or the last item has just run out. Stay around long enough though, and you can influence future stocks and perhaps practice. Once you depart, then your favourite “indispensable” surgical tools moulder on a high shelf. They only resurface once in a while and will eventually just provide amusement to the new generation of surgeons.
Look at Scott’s Parabola for a wry take on the problem.
Eventually, if your bit of kit is so outlandish and presents a menacing air to members of the general public, it will take a reverential place in a display cabinet in the hospital library. No one will remember what it did; perhaps that will be for the best.
