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

Its crazy how crude all of our tools look at this magnification.

[–] stebo02@lemmy.dbzer0.com 7 points 6 hours ago* (last edited 5 hours ago)

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.

Some medical tools look crude even at regular size… they don’t call orthopedics bone carpenters for nothing!

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!

[–] FlyingSquid@lemmy.world 2 points 4 hours ago

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.

[–] MrsDoyle@sh.itjust.works 25 points 12 hours ago (1 children)

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...

Lmao "oh shit I'm a house"

[–] SocialMediaRefugee@lemmy.world 4 points 9 hours ago

I've seen enough joint replacement videos, especially knees, to think carpentry skills are a job requirement.

Basically same as Orthodontists or Dentists. Once you arr knocked out, pray to not come back earlier :p

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.

[–] Warl0k3@lemmy.world 5 points 9 hours ago* (last edited 9 hours ago)

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.

Well at least they're not using a store brand.

My hospital buys from Harbor Freight!

[–] ChicoSuave@lemmy.world 21 points 14 hours ago (1 children)

I've started calling folks taking X-rays the bone paparazzi.

[–] peoplebeproblems@midwest.social 5 points 10 hours ago

I guess that's better than calling neurosurgeons spaghetti artists

[–] Kyle_The_G@lemmy.world 9 points 13 hours ago

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.

[–] SchmidtGenetics@lemmy.world 27 points 16 hours ago

I believe it’s damaged by piercing the skin, it’s pristine before.

[–] jawa21@lemmy.sdf.org 12 points 15 hours ago

Yet it emphasizes just how precisely tiny the tip of the needle is.
