章節 880: Chapter 778: This is How You Cut a Pineapple

```

Under the watchful eyes of the audience, Yang Ping began performing surgery on the pig, with Song Zimo and Xu Zhiliang serving as assistants. The Ultrasonography Department dispatched a doctor to operate the ultrasound machine, as the surgery needed to be conducted under the monitoring of esophageal echocardiography.

Traditional surgery requires opening the chest and using an electric saw to cut a long incision of at least 15 to 20 centimeters along the sternum, then prying open the chest cavity, cutting into the thick aorta, and entering the left ventricle through the aorta. The procedure of the surgery requires cardiac arrest and the use of extracorporeal circulation.

Yang Ping's new technique did not require such drastic measures; it only necessitated making a small 5-centimeter incision between the ribs on the left side of the chest. Using this small opening to enter the chest cavity, a puncture was made at the heart apex to insert the electric rotary cutter.
