AI Technical Summary
Existing irrigation systems in ablation procedures face challenges in maintaining a steady and continuous fluid flow rate, leading to inconsistent temperature control at the ablation site, which can result in tissue charring or cavitation, and excessive trauma due to unpredictable ablative energy delivery.
The use of a progressive cavity pump (PCP) to regulate irrigation fluid flow, controlled by a motor and servomotor, ensures a continuous and smooth flow rate of 1-2 ml/min, adjusted by temperature feedback, eliminating the need for special tubing and reducing noise.
Achieves precise temperature and power control at the ablation site, minimizing tissue damage and improving procedural efficiency by maintaining a stable irrigation flow, thus enhancing ablation quality.
