Abstract
An evacuation system and method for removing and/or treating gaseous and/or particulate byproducts of surgical procedures includes an end effector such as a side vent trocar, an operating room tower or the equivalent, a disposal vessel, a vacuum source and optionally a filter. The end effector may be coupled to the tower by a conduit, the tower may be coupled to the collection tank by a conduit, and the collection tank may be coupled to the vacuum source. Gaseous and/or particulate byproducts may flow from the surgical site through the trocar, conduits, tower tank and filter, and the flow may be regulated at least in part by the components of the system.
Claims15
An evacuation system for surgical settings comprising:
- a vacuum source configured for delivering a level of suction for removing smoke during open surgery;
- a flow regulator device fluidly coupled to the vacuum source, the flow regulator device comprising a flow rate adjuster;
- and
- a sensing and control system operatively associated with the vacuum source and the flow regulator and programmed to:
- cause delivery of a first level of suction via the flow regulator device based on a target pressure level to be maintained in a body cavity during laparoscopic surgery;
- receive a sensed level of pressure of the body cavity during laparoscopic surgery;
- and
- cause delivery of a second level of suction via the flow regulator device in response to a sensed level of pressure deviating from the target pressure, the first and second levels of suction being non-zero suction levels,
- wherein the flow regulator is adapted to adjust a level of negative pressure delivered by the vacuum source to provide a level of active suction for removing smoke from the body cavity during laparoscopic surgery.
An evacuation system for surgical settings configured to be coupled to a vacuum system for delivering a level of suction for removing smoke during open surgery comprising:
- a flow regulator device configured to be fluidly coupled to a port of the vacuum source, the flow regulator device comprising a flow rate adjuster;
- and
- a sensing and control system configured to be operatively associated with the vacuum source and the flow regulator and programmed to:
- cause delivery of a first level of suction via the flow regulator device based on a target pressure level to be maintained in a body cavity during laparoscopic surgery;
- receive a sensed level of pressure of the body cavity during laparoscopic surgery;
- and
- cause delivery of a second level of suction via the flow regulator device in response to a sensed level of pressure deviating from the target pressure, the first and second levels of suction being non-zero suction levels,
- wherein the flow regulator is adapted to adjust a level of negative pressure delivered by the vacuum source to provide a level of active suction for removing smoke from the body cavity during laparoscopic surgery.
