Cryoablation probe with cryogen flow disrupter
By incorporating a flow disruptor within the probe of the cryoablation probe, turbulence of the cryotherapy agent is induced, thus solving the problem of low thermal energy transfer efficiency in existing cryoablation probes and enabling faster cryo-ablation cycles and lower treatment costs.

AI Technical Summary
Technical Problem
Existing cryoablation probes have shortcomings in thermal energy transfer efficiency and cryocycle time, resulting in long treatment times and high costs.
Method used
A flow disruptor is placed inside the probe of the cryoablation probe to induce turbulence in the cryoprotectant, thereby improving the efficiency of heat energy transfer between the cryoprotectant and the tissue within the probe.
Benefits of technology
By introducing turbulence, the rate of heat transfer is increased, the cryo-cycle time is shortened, and the treatment cost is reduced.
