The colors are added in, of course, with it being an electron microscope image. Another picture:

      for this magnification it is actually pretty smooth

      source: I have used an SEM at my university and never saw something this smooth even at higher magnifications

      of course I didn’t look at medical tools but this shows that they are crafted very precisely

      It actually looks a LOT smoother and sharper than I expected. Look at microscope photos of razors and knives and they look like chewed up chisels.

        I’ve had 2 ACL reconstructions, but the first knee surgery I had was a scope. The surgeon allowed me to stay awake and it was freaking awesome to watch the little grinder and vacuum at work!

          Damn, I wouldn’t have been able to take that. I would have told them to put me the fuck out rather than have to see and hear it and realize that was my knee they were doing that to. Even though it was to make things better.

        People would never set foot in a hospital again if they found out how many orthopedic surgeries involve a dewalt drill at some point.

          My knee replacement was carried out with an epidural pain block, plus sedation. I came down from cloud nine briefly to wonder why someone was doing renovations while surgery was in progress - then realised all the drilling and hammering was my new joint going in. Phew! Back to lala land…

            That’s great. I rotated through an ortho lab in the 1990s, and the joint replacement kits back then included a sterile, disposable drill that you were just supposed to throw out after the procedure.

              I recently saw a knee replacement that used one of those ryobi oscillating cutters (the ones that were super trendy a few years back). Total garbage for home use, but man with a 3D printed cutting guide shaped to fit over the bone, they finished the osteo and arthroplasty portions in ten minutes flat. Just insane what we can accomplish when we combine modern volumetric imaging techniques with coupons for home depot.

        I gained an appreciation for how precise/sharp our tools are when I learned microtomy. If you so much as touch the cutting edge with anything outside of its intended use it messes up that area of the blade instantly. Same goes for a nice pair of chef’s knives.
