The size of the bipolar electrocoagulation tip kept getting smaller and smaller.
A laser knife cut into the substance of the spinal cord, further up, extending into the substance of the medulla oblongata.
Before the cross-section could show a faint hint of red indicating bleeding, bipolar electrocoagulation killed the bleeding points with a flash-like speed.
The carbonization points for hemostasis were very small. Under the microscope, only beautiful, tiny black spots were seen. The surrounding soft tissues were preserved very well.
The area it passed over was clean and clear.
Incredibly, there was virtually 'no blood' operation for patients with blood clotting issues.
After a few rounds, the tumor, like a sweet potato buried in the ground, began to show a bit of its surface.
From this point, the laser knife continued its sharp separation.
The visible surface of the tumor grew larger and larger, continually separating from the surrounding tissues.
