Needle insertion simulation problem

[Xavier]

Hello everyone!

I am working on a simulation project involving needle inserted into a soft tissue, mainly focusing on the needle deformation and interaction force. I’ve read several related published papers and unsurprisingly they didn’t talk much details about the collision configuration.

I have already build a basic simulation scene with the help of online documentation, example code and ,of course,the useful forum:). But I still have no idea about how to handle the needle-tissue interation process:
– what kind of collision should i choose?
– how to simulate the needle going though the tissue with cutting and friction forces? Is there any related example recommended?

Thanks in advance!

Hi @xavierleorio

I just answered a very similar question here.

Hi @xavierleorio

Now,Can you now simulate generating data for needle insertion into tissue? I am working on it. I want to learn it from you.If it’s convenient for you, can I have your code for generating datasets?

Hi Xavier,

Can I use your code of basic simulation scene ? I have no idea to do it.

Hi guys,

How things are running on your end @xavierleorio?

Note that a team is developing a Cosserat plugin (line mechanical model following the Cosserat beam theory). This plugin handles needle modeling and should handle needle insertion. It could be worth looking at it.

Best wishes,

Hugo
