CAD Models for Femur, Tibia, and Spinal Column 1

[jhilgart]

I currently looking to get a few CAD models: femur, tibia, and the spinal column in CAD so I can show the placement of instruments and implants I'm designing in a few of my presentations.

Unfortunately I'm very limited on time and do not have the capabilities at this time to generate the 3D models for them.

Does anyone have any insight on where to get CAD models without paying for them?

Thanks
Josh H

Try

http://www.3dcontentcentral.com

user library, miscellaneous, humans and go to page 2 "jim in a hurry" is a full skeleton but I haven't downloaded it so I don't know how good it is.
You will need to register but I think it is free.

user library just had a Tibia added. Click on "all models submitted in the last 30 days" and you will find it there.

If you want accurate models, you will have to pay for them.
I know you probably don't have 3D Studio, but this is an example of one:

Seems a lot of people have asked for that particular bone modeled in the past (tibia particularly, also femur). Strange. ..

Not so strange, look at the biomedical field right now, growing like gangbusters. tibia = knee, femur = hips, spine = spine!

If you want an actually good model, you will have to pay dearly:

We got a very nice spine model optimized for Solidworks (no messy polygons) but it cost a pretty penny. If you want something cheaper I would post it as a challenge in a 3d graphics forum, "who can make the best model?"

 

[jhilgart]

Thanks guys.

The tibia is an actually a pretty good model.

The "Jim in a Hurry model" does contain all the bones of the body featured as imported objects/polygons, but for representation it is pretty good.

The bones come in as imported objects with lines and planes in rather large polygons; however, you are able to delete all the unwanted bones which leaves any bone to the users discretion. I'm sure if you were able to place points and lines where the existing intersections are, then re-surface the model you could make it more accurate and then editable.

$6000 is a pretty penny for a 3d model.

Homework?

Exactly. ..certainly not here. ..

Well Crashj and Jeff, thanks for the USELESS comments. If you could find a post that offers the same helpful information the other guys left why didn't you just post it? Hmmm strange....

 

[Theophilus]

True. Sorry. ..

The best free models I've found are at this site:

http://www.tecno.ior.it/VRLAB/researchers/repository/BEL_repository.html

If you've the software to open them, it will save you a pile of $$$, and they are quite accurate, though the datum & reference plane work to get the femur and tibia, for example, properly aligned is a nuisance. If you want, feel free to email me (tghaines@earthlink.net) and I'll send you what I've already got for the knee joint (femur, tibia, fibula, patella & pelvis), but my best efforts to get a decent spine model still blow chunks.

If anyone comes across a good CAD model for the ankle/foot joint, I'd love a copy - Thanks

Try adding a split line thru the part.
Also, your dims in Sect A-A don't have dia symbols.

There are several software packages that will convert MRI or CT Scan data in to STL files. The new ScanTo3D software included in SW Office Premium will convert those STL file (or other polygonal mesh files) into usable surface and solid models for use in SolidWorks.

Haven't tried to get interior volumes yet, but exterior surfaces work quite well.
