摘要： Devices and methods for vacuum-assisted removal of surgically contaminated gas from an insufflated body cavity, the contaminants comprising smoke, aerosols, vapor, mist and the like generated during surgical procedures in order to clear the surgeon's vision of the surgical site and prevent exposure of the surgical staff to the gas. One embodiment of the present invention comprises a series of flow restriction devices to enable stepping down of the flow rate generated by an external vacuum. This reduced flow rate allows safe yet rapid removal of the toxic and vision-obstructing surgical byproducts from the patient's body cavity. The initial flow restriction device may comprise a perforated trocar sleeve in fluid communication with the vacuum source that allows retention of the surgical instrument within the trocar's inner lumen with concurrent smoke removal. The flow rate is infinitely variable, adjustable and selectable using a flow control adjuster comprising a smoothly varying orifice.

摘要： An apparatus and method for on-the-go humidifying an insufflation gas through water vapor transfer from a liquid to the insufflation gas through a barrier separating the gas from the liquid to enable the gas in a normally trauma inducing state to be brought to a conditioned state. If the gas is at an improper insufflation temperature the temperature of the gas can be brought to the proper insufflation temperature at the same time the gas is humidified through heat transfer through the barrier.

摘要： One aspect of the invention is an apparatus including an alarm for alerting an operator to recharge a humidifier, wherein such alarm is generated other than through the use of a humidity sensor. In one embodiment the total work performed during heating and hydrating an insufflation gas is measured and an alarm generated when the total work performed exceeds a particular threshold. In another embodiment, a flow meter is used to measure the total flow of insufflation gas so that when the total flow of insufflation gas reaches a predetermined level an alarm is activated.

摘要： A method and apparatus for treating gas for delivery into a body cavity, body space or body surface of an animal. The apparatus comprises a housing defining a chamber having an entry port and an exit port. One or more agents are released into the gas stream that flows through the chamber so that the gas stream carries the agent to the animal. Also shown, for use with, or without, the chamber, is an agent chamber adapted to be coupled to at least one structure defining at least one fluid flow path extending at least a portion of the distance between an insufflation device and the body cavity, body space or body surface.

摘要： According to one embodiment, a method includes positioning a portion of a trocar into a patient cavity and inserting a surgical instrument into the trocar. The method also includes measuring, by a pressure sensor disposed within the trocar, a pressure within the trocar. The measured pressure is indicative of a pressure in the patient cavity. The method also includes supplying, based at least in part on the measured pressure, an insufflation gas to the patient cavity by providing the insufflation gas through the trocar.

摘要： A method for supplying insufflation fluid to a patient cavity includes positioning a secondary trocar at least partially within a primary trocar, the secondary trocar being configured to facilitate delivery of insufflation fluid to a patient cavity. The method further includes, upon positioning the secondary trocar at least partially within the primary trocar, coupling the secondary trocar to the primary trocar thereby forming a trocar assembly. The method further includes coupling the primary trocar to a surgical robot and delivering the insufflation fluid to the patient cavity using the trocar assembly.

摘要： According to one embodiment, a trocar assembly having a proximal end and a distal end comprises an inner tubular member and an outer tubular member. The inner tubular member is formed with an opening at the proximal end and an opening at the distal end, the openings adapted to provide access for one or more surgical instruments during a surgical procedure. The outer tubular member is disposed about the inner tubular member, the outer tubular member being partitioned into at least a first chamber and a second chamber, wherein: the inner tubular member is separated from the outer tubular member by an inner wall; the first chamber is separated from the second chamber; and the first chamber and the second chamber are defined by the inner wall and an outer wall of the outer tubular member.
