For patients with hypertrophic obstructive cardiomyopathy, the product subversively changes the traditional thoracotomy into a minimally invasive surgery, avoiding most of the disadvantages of thoracotomy. The minimally invasive surgery does not require cardiac arrest and extracorporeal circulation, which is the first in the world. The surgical wound is small, the amount of bleeding is small, the postoperative recovery is fast, the curative effect is good, the incidence of complications is low, and it is safer. The new surgical method significantly reduces the difficulty of the operation, shortens the operation time, and reduces the learning curve for doctors. 1. Minimally invasive surgery method: Overcome the "fortress" of cardiac medicine, the world's first minimally invasive surgery without thoracotomy, non-stop beating, and no need for extracorporeal circulation. 2. Tissue fixation technology: When the heart is in motion, the product can grab and absorb the tissue, so that the product can fix the tissue and facilitate resection. 3. Cutting and sealing technology: multi-layer cutting head cooperates with reciprocating cutting, cutting without debris, with higher efficiency; good sealing to prevent blood leakage and tissue prolapse.Safety: During the operation, the heart does not need to be stopped and the extracorporeal circulation of blood is safer; the product has an insurance design, which can be used to release the device in an emergency. Ease of use: The two-hand partition grip is more stable, making it easier to adjust the cutter head to a suitable cutting position during the beating of the heart. The clear and easy-to-understand key sequence can complete a myocardium resection, and the instrument is easier to use.
