Understading control mechanics of a surgical device

AI Thread Summary
The discussion centers on understanding the control mechanics of a surgical device, specifically its movement transmission and scaling. The original poster, a heart surgeon, seeks clarification on how movement is transmitted, augmented, or dampened, referencing a linked PDF for context. Key points include the explanation of movement transmission in the document and the scaling of movement based on lever sizes. It is noted that equal-sized input and output levers result in unscaled movement, while differing sizes lead to proportional movement changes. The conversation highlights the need for a deeper understanding of these mechanics for effective surgical application.

Hello everyone,
This Moslem fathy, I am a heart surgeon,
This is a video of a surgical device, I would like to understand its mechanism in some
Aspects


http://psdl.engin.umich.edu/pdf/Awtar_JMedDev_FlexDex.pdf

this is a pdf that expalins the concept

I would like to know how the movment is transmitted, augmented or dampened

It appears to be reasonably well described in the paper you posted. See para 5.4 "Transmission system".
 
The scaling of movment is another point that I want to understand, how to do it? It just mentioned in the pdf but not how
 
If the input and output levers are the same size you get unscaled movement. If they are different sizes you get more or less movement proportional to the difference. Look at bicycle side pull hand brakes. You pull many centimeters but the brakes only move a small fraction of that.

Thread 'A practical way to vaporize fuel for high MPG?'

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
