Should I get the cell saver for my tummy tuck and lipo surgery?

Hello and thank you for your question.  I do not ever recommend cell saver for this surgery, as the amount of blood loss is minimal.  If you are an appropriate candidate for a tummy tuck, this can be done through a low and short
incision, all completely below the bikini line. 
The belly button can be designed to look natural and have no scars on
the exterior.   Your muscles can also be
plicated resulting in a flat abdomen. 
Make sure you specifically look at before and after pictures of
real patients who have had this surgery performed by your surgeon and evaluate
their results.  The most important aspect is to find a surgeon you are
comfortable with. I recommend that you seek consultation with a qualified
board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.

The cell saver is a great device for surgeries associated with  a large blood loss.  Abdominoplasties are rarely large blood loss surgeries, although a transfusion if there is post operative bleeding is not unheard of.  The cell saver would be prohibitively expensive as well - much more that the whole surgeon, OR, and anesthesia fees combined.
