Abstract:
1. A view optimizing assembly comprising a laparoscope, a sheath sized and configured to receive the laparoscope, a first lumen in a wall of the sheath for conveying a gas, a second lumen in a wall of the sheath for conveying a sterile fluid, a tubing set having a first tube and a second tube, the first tube having a first end sized and configured to couple to a source of gas and a second end coupled to a first part of a two part quick exchange coupler, the first part of the two part quick exchange coupler having a normally closed one way valve to normally prevent flow of the gas out of the second end of the first tube, the second tube having a first end sized and configured to couple to a source of the sterile fluid and a second end coupled to the first part of the two part quick exchange coupler, a manifold carried by the sheath and communicating with the first and second lumens, the manifold including a second part of the two part quick exchange coupler sized and configured to mate with the first part of the quick exchange coupler, the second part of the quick exchange coupler including an element that opens the normally closed one way valve in response to mating the first and the second parts of the quick exchange coupler to allow flow of the gas out of the second end of the first tube and into the first lumen, wherein the one way valve is configured to close in response to disconnecting the first and second parts to prevent the flow of the gas out of the second end of the first tube and into the first lumen; and a manual squeeze burst actuator in-line with the tubing set and configured to provide a burst of air through the tubing set.
