Abstract
Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.
Claims20
A surgical evacuation system, comprising:
- a pump;
- a motor operably coupled to said pump;
- a flow path fluidically coupled to said pump, wherein said flow path comprises a first filtering path and a second filtering path;
- a sensor positioned along said flow path upstream of said pump, wherein said sensor is configured to detect a parameter of a fluid moving through said flow path, and wherein the parameter comprises a liquid-to-gas ratio;
- and
- a control circuit configured to:
- direct the fluid along said first filtering path until the parameter detected by said sensor exceeds a threshold parameter;
- and
- direct the fluid along said second filtering path when the parameter detected by said sensor exceeds the threshold parameter.
A surgical evacuation system, comprising:
- a pump;
- a motor operably coupled to said pump;
- a flow path fluidically coupled to said pump, wherein said flow path comprises a first filtering path, a second filtering path, and a diverter valve movable between a first position and a second position, wherein a fluid is directed along said first filtering path when said diverter valve is in the first position, wherein the fluid is directed along said second filtering path when said diverter valve is in the second position, wherein said second filtering path comprises a condenser and a particulate filter, and wherein said first filtering path comprises said particulate filter and bypasses said condenser;
- a sensor positioned along said flow path upstream of said pump, wherein said sensor is configured to detect a parameter of the fluid moving through said flow path;
- and
- a control circuit configured to control said diverter valve based on the parameter detected by said sensor.
