Dr. Lu, with the finesse of a master, took the scalpel and widened the wound.
"Xiao Zhou, hurry and help with the retractor!"
Dr. Lu called out.
Zhou Can had no choice but to put down the film, pick up the retractor, and open up the wound.
It's worth mentioning that different retractors are used for different parts or tissues. For instance, L-shaped retractors are often used in mastectomy, abdominal wall surgery uses a large abdominal retractor, and a double-headed retractor is used for appendectomy.
When Zhou Can was an intern, he was scolded quite often by Director Liu or other doctors while assisting with retractors.
Later, as he assisted with more surgeries, he learned which retractor to use for which part and how to properly use it, and he was scolded much less frequently.
A great teacher produces outstanding students.
Director Liu's surgical skills are highly proficient, and Zhou Can has trained well in his retractor skills.
