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 housing comprising a display;
- a pump;
- a motor operably coupled to said pump;
- a flow path fluidically coupled to said pump;
- a sensor system, comprising:
- a first sensor positioned internal to said housing and along said flow path, wherein said first sensor is configured to monitor a first parameter of a fluid flowing through said flow path, wherein the first parameter is indicative of internal air quality;
- and
- a second sensor positioned on an external side of said housing, wherein said second sensor is configured to monitor a second parameter of the fluid exiting said flow path, wherein the second parameter is indicative of ambient air quality;
- and
- a control circuit configured to:
- interrogate said first sensor for the first parameter and said second sensor for the second parameter;
- analyze the first parameter and the second parameter to compare internal air quality to ambient air quality and determine an efficiency level of the surgical evacuation system relative to the ambient air quality;
- and
- control the flowrate over time based on the determined efficiency level.

A surgical evacuation system, comprising:
- a housing comprising a motor and a pump configured to generate a flowrate;
- a flow path through said housing;
- an internal sensor positioned within said housing, wherein said internal sensor is configured to monitor an internal parameter of a fluid flowing through said flow path;
- and
- an external sensor positioned on an external side of said housing, wherein said external sensor is configured to monitor an external parameter of ambient air;
- and
- a control circuit configured to:
- interrogate said internal sensor and said external sensor over time to determine the internal parameter and the external parameter, respectively;
- analyze the internal parameter and the external parameter over time to determine an efficiency of the surgical evacuation system relative to the external parameter of ambient air;
- and
- control the flowrate over time based on the efficiency of the surgical evacuation system relative to the external parameter.
8 more elements
A surgical evacuation system, comprising:
- a housing comprising an inlet port and an outlet port;
- a display;
- a pump;
- a motor operably coupled to said pump;
- a flow path fluidically coupled to said pump, wherein said flow path extends between said inlet port and said outlet port;
- a sensor system comprising:
- an internal sensor positioned to monitor a first parameter;
- and
- an ambient air sensor positioned on said housing to monitor a second parameter of the ambient air;
- and
- a control circuit configured to:
- interrogate said internal sensor and said ambient air sensor for the first parameter and the second parameter, respectively, to determine an efficiency of the surgical evacuation system relative to the ambient air;
- and
- control the flowrate over time based on the determined efficiency.
