Awwwww............I'm so, so sorry this happened to you. I can definitely relate to the feeling of helplessness. Don't know of any mechanical type thing to get you back on your feet, two "hunky" men could do it!
From a seating position in a chair to standing, one
strong person can lift with the "bear hug". You put your arms around their neck, they give you a bear hug and stand up. For me it worked getting me into my chair since my legs don't work. Careful though so nobody gets hurt. It would be pretty far for the lifting person to bend over though (all the way to the floor). Anyway for what it's worth.
Hugs are always a good thing.....
