AI Technical Summary

Technical Problem

Existing ablation and rotary cutting equipment is prone to problems such as fluid pipe blockage and low suction and waste removal efficiency when dealing with different physiological loads. Especially when dealing with high-density or high-toughness tissues, the negative pressure suction mode is not dynamic and precise enough, resulting in pipe blockage and reduced waste removal efficiency.

Method used

By synchronously extracting and processing the phase current signal of the cutting motor driving the ablation rotary cutting device and the air pressure fluctuation signal of the vacuum conduit interface, multi-modal fusion technology is used to reconstruct the rotation phase angle of the cutting window and the equivalent cutting specific energy. The control mode of the flushing and vacuum solenoid valves is dynamically adjusted to generate a fluid transient suction effect with the same frequency as the mechanical opening, thereby avoiding negative pressure waste and improving suction efficiency.

Benefits of technology

It effectively solves the problems of fluid pipe blockage and low suction and waste discharge efficiency, ensuring high efficiency and safety of the ablation and rotary cutting process, and significantly improves the equipment's suction and waste discharge capacity through a dynamic pulse control mechanism.
