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.
Claims21
A surgical evacuation system, comprising:
- a pump;
- a motor operably coupled to said pump;
- a flow path fluidically coupled to said pump;
- a housing, comprising an inlet and an outlet, wherein said flow path extends between said inlet and said outlet, and wherein said pump and said motor are positioned within said housing;
- a sensor system, comprising:
- a first pressure sensor positioned along said flow path;
- and
- a second pressure sensor positioned along said flow path upstream of said first pressure sensor;
- and
- a control circuit configured to:
- determine a pressure differential between said first pressure sensor and said second pressure sensor;
- adjust a duty cycle of said motor based on the pressure differential;
- and
- transmit at least one surgical evacuation system parameter to a surgical hub, wherein the surgical hub is configured to aggregate data from a plurality of data sources comprising the control circuit and sources separate from the surgical evacuation system and is configured to display a plurality of parameters comprising the at least one surgical evacuation parameter.

A surgical evacuation system, comprising:
- a pump comprising a motor;
- a flow path fluidically coupled to said pump;
- a housing, comprising an inlet and an outlet, wherein said flow path extends between said inlet and said outlet, and wherein said pump is positioned within said housing;
- a sensor system, comprising:
- a first pressure sensor positioned along said flow path to detect a first pressure;
- and
- a second pressure sensor positioned along said flow path upstream of said first pressure sensor to detect a second pressure;
- and
- a control circuit configured to:
- determine a ratio of said second pressure to said first pressure;
- determine an operating condition of the surgical evacuation system based on said ratio;
- and
- transmit the operating condition to a surgical hub, wherein the surgical hub is configured to aggregate data from a plurality of data sources comprising the control circuit and sources separate from the surgical evacuation system and is configured to display a plurality of outputs comprising the operating condition.
10 more elements
A non-transitory computer readable medium storing computer readable instructions which, when executed, cause a machine to:
- receive a first signal from a first sensor positioned along a flow path through a surgical evacuation system;
- receive a second signal from a second sensor positioned along the flow path through the surgical evacuation system;
- determine an efficiency ratio of the surgical evacuation system based on the first signal and the second signal;
- redirect the flow path internally through the surgical evacuation system;
- adjust an operational parameter of a pump motor of the surgical evacuation system based on the efficiency ratio;
- and
- transmit the efficiency ratio to a surgical hub control circuit, wherein the surgical hub control circuit is configured to aggregate data from a plurality of data sources comprising the non-transitory computer readable medium and sources separate from the non-transitory computer readable medium and is configured to display a plurality of outputs comprising the efficiency ratio on a surgical hub display.
