Xiang Yuanzhong personally made a pinky promise with Li Zheng, while Guo Weiqiang was responsible for adducting and internally rotating the entire leg to fully expose the acetabulum.
Li Zheng placed the acetabular rasp into the acetabulum and was about to start the electric drill.
Xiang Yuanzhong couldn't help but remind him, "Will it wear through the acetabulum?"
Li Zheng shook his head and said, "No, there is still too much hardened bone. You have only worn away most of it. There is still a small part that needs to be completely worn away."
After saying that, Li Zheng started the electric drill.
“Squeak…”
Li Zheng was shaking the connecting rod while polishing the bottom and edge of the acetabulum.
Xiang Yuanzhong was horrified when he saw this.
He studied joint replacement, and in theory, the connecting rod should not be shaken during this step, as that would cause uneven wear of the acetabulum and affect the matching of the acetabular cup.
Why does Li Zheng look like he's messing around?
Looking at the amplitude of his shaking, it was like he was stirring cement slurry.
Duan Jianhui, who had already stood up, sneered when he saw what Li Zheng did.
If you don't even understand the most basic theoretical basis, this is pure nonsense.
Okay, very good. This has nothing to do with me now. You guys ruined it.
Li Zheng worked on it for a while and then took out the acetabular rasp.
"Wipe the blood, don't just stand there." Li Zheng reminded.
Xiang Yuanzhong quickly recovered from his shock, picked up the gauze ball with curved forceps, and wiped the blood out of the acetabulum.
"Hey, it seems like the bleeding has increased!" Bao Youshan said with a little surprise.
"Really?" Bao Youshan stretched his head and tried to look inside, but he couldn't see clearly.
The other doctors also showed curious expressions and wanted to see it with their own eyes.
"One size bigger." Li Zheng handed over the connecting rod.
"Okay, it's number 38!"
The engineer quickly replaced it.
Li Zheng put it in to grind again, but this time the swing amplitude was not as large.
Taking it out again, Xiang Yuanzhong wiped the blood off immediately.
"Haha, there is really more bleeding, and it is evenly distributed on all sides!" Xiang Yuanzhong began to get excited.
Others also began to look forward to it.
If the bone surface bleeds abundantly, it means that the cancellous bone has been completely worn away. Hardened bone does not bleed much.
Now everyone finally understood that the reason why Li Zheng was stirring the bone like stirring cement just now was to grind off as much hardened bone as possible. Otherwise, the operation would not be successful!
"Keep increasing it."
The engineer became very excited. If they succeeded, they could save a month's salary.
"Number 40!" the technician announced loudly. This is what the hip heel support must do, and the surgeon must know the current model.
After another round of operations, Li Zheng's swing amplitude became smaller and smaller, and the shape of the acetabulum became closer and closer to the standard semicircle.
…
"Number 46!"
…
“Number 58!”
…
"It's number 50!" the engineer shouted.
Li Zheng took the instrument, continued grinding, and took out the acetabulum rasp.
After wiping the blood, Xiang Yuanzhong looked at the acetabulum in a daze.
"Director Xiang, what's wrong with you?" asked Dean Zhang.
Xiang Yuanzhong came back to his senses, his eyes gleaming with a brilliance he had never seen before, and he excitedly said, "This acetabulum is so beautiful, so perfect!"
Everyone was cheered up.
"Really? Let me see!" Bao Youshan shouted from the outside.
"Go away. Don't you see Dean Zhang?" Xiang Yuanzhong glared.
Bao Youshan quickly stepped aside. Dean Zhang came over, stood on tiptoe to take a look, and nodded. "The entire acetabular surface is bright red. It's been polished so evenly. The cancellous bone looks so comfortable!"
Chen Dayong also wanted to take a look, but was suddenly pulled away.
Duan Jianhui arrived at the operating table at some point.
"Director Duan, what are you doing?" Chen Dayong asked.
Duan Jianhui snorted coldly, "Why, are you the only one who can see it?"
Chen Dayong laughed and said, "Well, Director Duan wants to learn, so I'll give it to you!"
As he spoke, Chen Dayong made way and Duan Jianhui stretched his head to look inside.
boom!
The moment Duan Jianhui saw the acetabulum, he felt like he was struck by lightning.
This was the first time he had seen such a beautiful acetabulum. He had never seen one even during the year he was studying in the province!
This Li Zheng is definitely an expert in joint replacement!
"Director Duan, how is it?" Director Zhang asked with a smile as he left the operating table.
Others also looked at him curiously, after all, he was nominally the most professional here.
Duan Jianhui came back to his senses, his eyes lingering on his acetabulum for a long time.
He sighed and said, "This is the best-polished acetabulum I've ever seen. Even a fresh acetabulum from a femoral fracture isn't polished this well. The bone is so hardened, yet it can be polished to perfection. Li Zheng, it's hard for me to imagine you haven't done this surgery before!"
The others nodded, unable to believe it!
Li Zheng was a little depressed. His performance was too outstanding, but his identity and experience did not match it, so he had to explain. However, no matter how he explained, it would seem unreasonable. It seemed that he had to keep a low profile in the future.
Li Zheng explained with a smile, "As long as you have a good understanding of anatomy and the principles of surgery, you'll be able to perform with ease. For example, in this operation, your biggest concern was that continued grinding would cause the acetabulum to perforate. However, after looking at the film, I was able to construct a three-dimensional image of the acetabulum in my mind. I can infer that you haven't ground deep enough, so I can boldly deepen it!"
Everyone was completely dumbfounded after hearing this.
Can simulate three-dimensional through film!
What kind of incredible ability is this?
"Li Zheng, you're truly... a genius!" Xiang Yuanzhong gave him a thumbs-up, convinced. Three-dimensional spatial perception is crucial in orthopedic surgery, especially without C-arm fluoroscopy. Inserting screws and needles relies entirely on intuition. Having this ability significantly improves surgical efficiency and safety.
