Abstract
A trocar for performing a surgical procedure on a patient. The trocar includes a hollow cannula having a distal end and a proximal end, and a housing having a distal end attached to the proximal end of the cannula and a proximal end having a wall attached thereto. Wherein the wall has an aperture therethrough for inserting surgical instruments into the trocar. The trocar includes a hollow tubular guide member having a proximal end attached to the wall about the aperture and a distal extending therefrom The trocar has a first seal comprising an elastomeric conical member having a proximal end adjacent to the distal end of the guide member, and a distal end extending therefrom, the distal end of the member having an opening therethrough. The trocar also has a second seal having an open position and a closed position, wherein when the second seal is in the open position there is fluid communication between the aperture and the cannula, and wherein when the second seal is in the closed position, fluid communication between the aperture and the cannula is substantially prevented.
