Fun fact, that is hammered onto your femur to ream out the marrow for a hip replacement. It's not a delicate process either, the docs are swinging at that mf full force

So fun

[u/Fantastic_Bird_5247 → u/not_cozmo]

Yes this man speaks the truth, I used to make these tools!! Don’t ever break your hip!!

[u/kevdogger → u/not_cozmo]

No they don't. It's a hand rasp meant to lateralize on the femur to prevent varus positioning of femoral stem. Some may use it as a canal finder per se however you then use it like any hand rasp. The rasp pictured is a very old design and usually more modern rasps have a much more curved design where the handle meets the body of the rasp

Must cost a fortune; single use only?

[u/DrieverFlows → u/sinisteraxillary]

Bought at a yard sale. I'd use it for wood

[u/sexytimepizza → u/DrieverFlows]

You've got me beat for weirdest repurposed tool. I have a solid aluminum suppository mold that I've used for casting lead fishing weights, and for making incense "cones" (I guess they're suppository shaped, and not actually cones lol). For external combustion only, though. internal use not recommended lol.

[u/DrieverFlows → u/sexytimepizza]

I think this is weirder bro

[u/Zillahi → u/sinisteraxillary]

Ah chuck it in the dishwasher it’ll be fine

[u/mrkrag → u/Zillahi]

Exactly how they do it. Big ass washer kind of like restaurants use. Then into the sterilizer.

[u/mrkrag → u/sinisteraxillary]

No, it's not an implant, the tools are resterilized and used for years.

[u/Fantastic_Bird_5247 → u/sinisteraxillary]

A few thousand each depending on which vendor is buying them. More if they hold a specific tool of implant.

We made ones like the one pictured above that would release the rasp end when you depressed a level. They looked like weapons from StarTrek / the Klingon wars 😆

[u/Memento101Mori]

Made of titanium?

[u/DrieverFlows → u/Memento101Mori]

I think so.

[u/mrkrag → u/Memento101Mori]

Surgical stainless. People seem to think all metal in the OR is titanium.

It's crazy that this looks like it's genuinely hand-stitched. It's hard to find people who do that for woodworking quality rasps, i can't imagine how tight the market is for medical grade.

[u/Real_Camera_1287]

And I thought it was a bedroom “toy” !!!

[u/Imbeautifulyouarenot]

Looks like something used for a hip implant. :)

[u/mrkrag → u/Imbeautifulyouarenot]

Medullary Reamer. They come in the same shapes and sizes as the implants. You work these in,going up in size until you get a good fit for the actual implant. 

[u/Imbeautifulyouarenot → u/mrkrag]

Thank you for the information. There must be many special tools for surgery such as this one. :)

[u/mrkrag → u/Imbeautifulyouarenot]

Sooooo many. I work in orthopedic surgery, partly because I enjoy and I am good at using tools. And we get some cool ones. We also get some stuff i would swap out for something I have at home of it were allowed. 

[u/o_zimondias]

Goddamit my bone ache now

[u/trk1000]

My brain just thought about the sensation...

[u/mclearen1987]

Ow, my bones

[u/Fantastic_Bird_5247]

I worked for a company that made these and other tools for hip implant surgery.

We were required to REALLY TEST each tool because the doctors wail on these things with hammers to put the implants in. If the tools fails it gets really ugly, and they made us watch videos of what happens.
