Zusammenfassung:A surgical cannula for providing insufflation gases to a surgical cavity of a patient (for example, the pneumoperitoneum) and allowing insertion of medical instruments into the surgical cavity through the cannula can include a heater within or coupled to the cannula. The heater can heat the gases and/or the instruments to raise the temperature of the gases and/or instruments above a dew point of the gases to prevent fogging. The heater can also help to defog a lens of a medical instrument by heating to clear the lens and improve optical clarity.
