The middle-aged woman from Shanghai who was under regional anesthesia went silent for a few minutes.
Within that short span of time, Ling Ran had used the conventional method to insert the arthroscope into the patient's knee joint.
The outward appearance of an arthroscope was similar to that of a long metal rod. It was also very thin.
The camera was located at the front portion of the thin metal rod. It was used to film the interior of the knee joint, which would be broadcasted on the screen above the operating table.
In American movies, you would often see members of the SWAT team insert a long and soft metal rod into a house before they observed what was going on in the house through a screen outside the door. Basically, arthroscopes had the same function as those metal rods.
The only difference was that the members of the SWAT team had a view of a large room, while the surgeons had a view of a tiny space.
