The suction can be quite strong especially damaging to tissues that are damaged, friable, and paper thin from the treatments. Any suction device must have some means for controlling the amount of suction at the tip so it can be turned down low. I have even see these for sale on eBay, besides the local medical supply stores.

We have had posters here use them successfully, but doctors as a rule do not like them as they can sometimes, when used on delicate tissues by someone who is doing much of the job by feel, not visually, cause significant harm.
