MEDiTHREAD needle or cannulas. Each area has its own tool.
MEDiTHREAD needles have the same outer diameter of traditional needles but having a bigger bore (inner) diameter allowing patients to feel less pain and makes the needle more flexible so easier to place in not even surfaces.
Having a bigger bore allows for a thicker thread to be placed in the needle and gives more space to retract the needle without thread catching. This is why MEDiTHREAD needles are the best!
