Devices and methods are provided for removing fluid from a surgical access device and/or from surgical instruments passed therethrough, and for preventing suc h fluid from accumulating. For example, in one embodiment, an exemplary device can includ e a body defining a working channel that is configured and sized to allow for passage of a surgical instrument therethrough. A number of seals can be disposed in the working channel so as to contact the inserted surgical instrument. One or more outlets can be oriente d to direct gas, such as air or an insufflation gas, into the working channel so as to remove flui d on the seals, or other parts of the surgical access device, as well as the surgical instruments themselves. In some embodiments, constant flows of gases can be arranged to act as shields to he lp prevent fluid from accumulating on the surgical access device and/or surgical instruments. |
