Abstract
Surgical systems are disclosed. 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 system, comprising:
- an evacuation system, comprising:
- a pump;
- a motor operably coupled to the pump;
- a flow path fluidically coupled to the pump;
- and
- a sensor positioned along the flow path, the sensor to measure a particulate concentration of a fluid flowing along the flow path;
- a generator to supply a signal to an electrosurgical instrument;
- and
- a control circuit to regulate a speed of the motor based at least in part on the particulate concentration measured by the sensor and a power level of the signal supplied by the generator.
A method, comprising:
- supplying, by a generator, an electrosurgical signal to an electrosurgical instrument;
- receiving, by a control circuit, a signal from a sensor of a surgical evacuation system, the surgical evacuation system further comprising:
- a pump;
- a motor to drive the pump;
- and
- a flow path fluidically coupled to the pump, wherein the sensor is positioned along the flow path and is to monitor a particulate concentration in a fluid flowing along the flow path;
- and
- regulating, by the control circuit, a speed of the motor based at least in part on the particulate concentration measured by the sensor and a power level of the electrosurgical signal supplied by the generator.
A non-transitory computer readable medium storing instructions executable by at least one processor of a control circuit causing the control circuit to:
- receive a signal from a sensor of a surgical evacuation system, the surgical evacuation system further comprising:
- a pump;
- a motor to drive the pump;
- and
- a flow path fluidically coupled to the pump, wherein the sensor is positioned along the flow path and is to monitor a particulate concentration in a fluid flowing along the flow path;
- adjust a speed of the motor based at least in part on the particulate concentration measured by the sensor;
- and
- adjust a parameter of an electrosurgical signal supplied by a generator to an electrosurgical instrument based at least in part on the particulate concentration received from the sensor.
