Ultrasound ablation is a kind of thermal ablation treatment, which is a development and supplement of the traditional surgical resection treatment technique, a technique that does not operate, but may achieve the effect of open local excision of the lesion. Its main features are.
One, it is a non-invasive treatment technology, not only there is no incision, but also no puncture needle, it uses ultrasonic waves to play the treatment effect through the body surface to the body, so that there is no risk of bleeding, and there is no risk of tumor planting and metastasis along the needle channel or incision, meanwhile, because there is no incision, compared with invasive treatment, the trauma is small and the recovery is fast, at present, ultrasonic ablation treatment technology is the only clinically applied non-invasive Currently, ultrasound ablation is the only non-invasive ablative treatment technique used in clinical practice. Other local ablation treatments, such as radiofrequency ablation, microwave ablation, laser ablation, alcohol ablation, etc., need to be treated with the help of puncture.
Ultrasonic ablation therapy is to treat a large lesion by controlling the movement of the focal point formed in the body from outside the body through image monitoring, and finally finish the treatment of a large lesion, the range of focal point movement is large, and the focal point can be moved according to different shapes of the lesion, so as to achieve the purpose of treating lesions of different sizes and shapes, so it is also called a kind of conformal treatment. At present, the lesions treated by ultrasound ablation can reach 10 to 20 centimeters in diameter. Other puncture ablation techniques cannot treat such large lesions at present, and it is difficult to achieve conformal treatment.
