This application relates to the field of medical devices and discloses a needle withdrawal system for radiofrequency ablation devices that avoids scarring. Based on a standard radiofrequency ablation device, the system integrates a needle position detection device (real-time monitoring of depth and speed) and a needle tip temperature sensor. During needle withdrawal, the radiofrequency power is dynamically adjusted according to the withdrawal speed (higher power for faster speed); when the needle tip depth is less than a predetermined threshold (close to the body surface), the radiofrequency output is automatically stopped and a prompt to wait for cooling occurs; once the temperature drops below a safe threshold, a prompt indicates that the needle can be completely withdrawn. Through this closed-loop control, the thermal coagulation and end-point cooling processes of the needle track are precisely managed, effectively preventing thermal damage to the skin and subcutaneous tissue and significantly reducing scar formation.
