Torsion Spring for Medical Device

Have you tried going to any spring manufacturer websites?

such as this?

Here's where I go for mine sometimes.

If you want a top level supplier who understands the medical device needs, call these folks, they have bailed me out many times.

Chris Witham or tim Holt would be the starting point. They have helped us through R&D and volume production with many designs.

Hi,

in the last ? years I did design many different flexures - most highly specialised so I expect that I can give you a solution if you don't find what you need.

Torsion spring produces torque not a force. If you define a force you should specify the spring arm length that the force is acting on. Added to it you should specify the spring angular deflection under the force or forces. Next you should define the number of loading cycles (fatigue design) if applicable. etc.

You are right. Some of RHABE's products seem impressive though. Very specific jobs I think. Try to use the existing supply houses if you can. Custom jobs can kill you on the tool-up unless your expecting a volume run. Good luck. I,m on my home laptop at the moment; someone let me know if it's any smarter.
