A surgical system 10 includes a cannula 12 having a hub 14 for insertion through an incision 18 at a surgical site 20. The cannula 12 has a lumen 22 extending from a distal end 24 through the hub 14. A surgical instrument 26 is for insertion into the cannula lumen 22. Vibration dampening material 30 is formed on at least one of the cannula 12 and the surgical instrument 26. The vibration dampening material 30 reduces transmission of vibrations from the surgical instrument 26 to the surgical site 20, thus reducing unwanted heating of the surgical site 20.
