I can... but I'm highly reluctant to deprive you of the opportunity to do your own research.

I will tell you that using a Ctrl-F search of Section 4 of the Manual turned up no references to surgical tubing or elastic or springs; it did turn up a few references to tubing, but all of them were pneumatic tubing.
