need to bulk change product names on a e-commerce site

Hi,
I have a site i'm building for a client which is located at:
http://www.rrgsupplies.com/

This site uses products that have been imported. The problem is that any product that says CLIA or CliA Wave needs to be changed to a different name. Does a plugin exist that can do this? This site uses woo commerce. Can that be done on products?
