the filling pipeline comprises an input interface, a two-way valve, a bubble flushing outlet and a catheter saline filling port, wherein the bubble flushing outlet and the catheter saline filling port are respectively connected with the output end of the two-way valve;
the perfusion pump comprises a core system control module, a bubble detection module and a peristaltic pump, wherein the bubble detection module and the peristaltic pump are connected with the core system control module;
the bubble detection module is used for detecting whether bubbles exist in the perfusion solution in the front pipeline of the input end of the two-way valve;
when bubbles exist, the output end of the two-way valve is controlled to be switched to the bubble flushing outlet through the core system control module, and the peristaltic pump is controlled to lift the liquid flow rate at one end of the perfusion pipeline input interface for discharging the current perfusion solution;
when no bubble exists, the output end of the two-way valve is controlled by the core system control module to be switched to the catheter saline filling port, so that the filling solution is used for subsequent filling treatment.
2. The automatic bubble-flushing perfusion apparatus of claim 1, further comprising: an interaction module;
the interaction module is connected with the core system control module and is used for responding to the interaction operation of an operator through the interaction module, and the core system control module generates a corresponding control instruction so that the peristaltic pump can adjust the liquid flow rate at one end of the perfusion pipeline input interface.
3. The automatic bubble-flushing perfusion apparatus of claim 1, further comprising: an alarm module;
the alarm module is used for warning an operator when bubbles are detected to appear in the perfusion pipeline.
4. The automatic bubble-flushing perfusion apparatus of claim 1, further comprising: a communication module;
the communication module is externally connected with an ablation instrument and is used for configuring different perfusion flow rate parameters according to the catheter ablation working state.
5. The automatic bubble flushing and filling device according to claim 1, wherein the input port of the filling pipeline is a solution bag plug, the filling pipeline is connected with an infusion bag, and the main body of the pipeline is a squeezing-resistant hose.
6. The automatic bubble flushing perfusion apparatus of claim 1, wherein the bubble monitoring module includes an ultrasonic sensor and a comparator;
the ultrasonic sensor is used for monitoring bubbles in the perfusion pipeline in real time, the ultrasonic sensor comprises an ultrasonic generating device and an ultrasonic receiving device which are oppositely arranged on two sides of the perfusion pipeline, ultrasonic waves are emitted by the generating device, penetrate through the perfusion pipeline and physiological saline in the perfusion pipeline and return to the ultrasonic receiving device, the received ultrasonic signals are compared by the comparator, the volume of the bubbles in the perfusion pipeline is determined based on the comparison result, and when the volume is larger than a preset value, the bubbles are judged to exist in the perfusion pipeline.
7. The automatic bubble flushing perfusion apparatus of claim 5, wherein the perfusion tube is externally connected with an infusion bag in a multistage series connection.
8. The automatic bubble-flushing perfusion apparatus of claim 4, wherein the peristaltic pump flow rate control includes three modes:
low flow rate mode, flow rate range is set as: 2ml/min to 5ml/min;
high flow rate mode, flow rate range is set as: 6ml/min to 60ml/min;
flushing mode, flow rate set to: 100ml/min.
9. The automatic bubble irrigation device according to claim 8, wherein the communication module is further configured to obtain an operating state of an external ablation instrument, switch to the high flow rate mode during radio frequency thermal ablation, and switch to the low flow rate mode during stopping ablation or pulsed electric field ablation.
10. A surgical robot comprising an irrigation device of an automatic irrigation bubble according to any of claims 1 to 9 for completing an ablative surgical procedure in response to an operator manipulation.
