In accordance with one embodiment of the present disclosure, a surgical method may include making an incision in a patient. The method may also include opening the incision in order to create an open surgical site in the patient. The method may further include receiving a gas from a source. The method may further include humidifying and warming the gas received from the source. The method may further include successively reflecting the humidified and warmed gas off a plurality of non-porous surfaces within a non-porous gas delivery mechanism to create a flow. The method may further include delivering the flow of the humidified and warmed gas adjacent to or into the open surgical site.

Surgical method for performing an open surgical site surgery

An apparatus and method for clearing of a surgical site during the performance of a medical procedure where a single phase wash fluid, which has been conditioned, is directed at the surgical site to inhibit or prevent harm to the body tissue as unwanted debris is blown away from the surgical site thereby permitting a surgeon to safely perform a medical procedure without the presence of unwanted liquids or unwanted debris at the surgical site.

Medical devices for clearing a surgical site

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.

Device and method for controlling the flow rate of evacuating surgical vapor and mist from a body cavity

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 sleeve's inner lumen with concurrent smoke removal. A series of additional flow restriction devices located downstream of the perforated sleeve's intake ports are employed to safely limit the flow rate to a manageable and known value.
