There are few patients, the ward rounds are fast, and after the ward rounds, Zhang Lin and Xiao Wu send the patients to the operating room.

Meniscus suture and cruciate ligament reconstruction are landmark knee arthroscopic surgeries, although Director Han is very relieved of Yang Ping, but these landmark surgeries, or go up and see how powerful Yang Ping's arthroscopic surgery is.

Huang Jiahui waited in the operating room early, waiting for the instrument cart, she stacked 20 individually sterilized meniscus suture guns neatly on the instrument cart, and locked the instrument cart in an unobstructed corner next to it.

This corner is the best place for her to think about it and find it.

It is convenient to observe the progress of the operation without hindering the personnel in the operating room.

She used to have enviably long hair, but since she entered the industry, she has decisively cut it short, just short enough to tie it up.

Today she tied her hair up, wrapped it in a net, and put on a sterile cap with no hair showing a bit. Trained to wear a sterile cap, she practiced countless times in front of the mirror at home until not a single hair was exposed.

The anesthesia has been prepared, Song Zimo hung the patient's X-ray and magnetic resonance film on the reading lamp, instructed Xiao Wu and Zhang Lin to set up their positions, and then went to brush their hands, disinfect the sheets, and make preparations, and every detail was meticulous.

When Yang Ping washed his hands and came in, everything was already ready, just waiting for the stage to open.

When Yang Ping was wearing a surgical gown, Director Han came in.

"Hello Director!" Everyone said hello.

"Hello, Professor Han!" Director Han, who followed up with Jiahui, greeted and bowed.

"Hello!" Director Han saw that she was holding a laser pointer in her hand and guarding the sterile boxed instruments, and knew that it was the instrument dealer who followed the stage.

"Which company? New to the new arrival? ”

Director Han had never seen this little girl before.

"Professor Han, I'm new here, Ruixing Medical, making sports medicine products." Jiahui introduces herself.

Director Han picked up a separately wrapped meniscus suture gun and looked: "Ruixing!" Domestic, you should support more domestic ones, this stitching gun sometimes jams, pay attention! ”

"The connection between the first needle and the second needle is not accurate, sometimes the strength is not well controlled, and there will be an error of 0.5 mm. After the first shot, you can't release the trigger, you still have to pull the trigger to death, and then go back until you confirm that the first shot is off the gun, then release the machine, and then hit the second shot, so that there will be no jamming, this design needs to be improved. ”

Yang Ping has studied Ruixing's equipment very deeply, and before Huang Jiahui reminded him, he already knew about this defect and already had countermeasures, so he just didn't care.

"You have a deep study of the device, which is right, the doctor must be proficient in the study of the device by himself, and cannot rely on the explanation of the manufacturer on the stage." Director Han appreciated Yang Ping's attitude.

"What's going on with this patient?" Director Han asked while watching the film.

"Male, 14 years old, professional football player, compound tear of the medial meniscus of the left knee, the tear is located in the posterior horn and body." Yang Ping introduced Luo Xiaohu's condition to Director Han.

"Hmmm! Looking at the magnetic resonance, the meniscus tear is serious, and the suture technique is difficult, so do it slowly and not in a hurry. Director Han explained to Yang Ping.

Huang Jiahui moved a stool and asked Director Han to sit.

Complete the preoperative check, drive blood, and inflate the tourniquet.

Yang Ping began to sharpen the knife opening, skillfully opened on the outside, entered the puncture cone with the sheath, then straightened the knee joint, entered the suprapatellar capsule, pulled out the puncture cone, and inserted it into the lens.

While speaking, the arthroscopic exploration of the knee joint has been completed, the medial meniscus is torn, and no other obvious abnormalities have been found, and the medial meniscus can be sutured.

Director Han moved to the side of the screen and looked at the video image above: "The tear is very serious, one piece has been turned up, and it is freshly torn?" ”

"It's only been two days since the tear, and this is the patient introduced by Su Nanchen, an athlete from the provincial youth football team." Yang Ping began to insert needles on the inside to guide the opening.

After opening, the probe is inserted, and the probe is an extension of the arthroscopist's finger, which can further understand the lesions and injuries of the structure through fiddling and touching.

Yang Ping closed the water inlet pipe, which could reduce the agitation of the torn meniscus by flowing water, and use a probe to return the torn meniscus to its place and smooth it. Freshly torn, directly sutured, no need to do fresh treatment of the edge of the tear.

"Stitch guns!"

Xiao Su also did research on the manufacturer's equipment in advance, and when Huang Jiahui asked her to test the sterility knowledge record, she also asked Huang Jiahui for the details of these devices.

Yang Ping took the suture gun, entered through the medial opening, and began to suture the posterior angle of the meniscus, the muzzle of the gun was aimed at the proposed puncture point, pulled the trigger, and the tip of the needle pierced the meniscus with a thread anchor until it pierced the joint capsule of the meniscus attachment, and the riveting of the thread remained outside the joint capsule.

He tightly pulled the trigger and did not let go, pulled back gently, the first needle smoothly took off the gun, 0.5 cm away from the first needle, the muzzle of the gun against another proposed puncture point of the meniscus, pulled the trigger, the second needle entered smoothly, and the gun was withdrawn backwards.

Tighten the sutures, the two thread anchors are threaded longitudinally, and now when they are pulled, they become transverse, pinned behind the joint capsule, and become the anchor point of the thread. The knots are all prefabricated, irreversible, and can only be tightened, not relaxed.

Use the knot pusher to send the knot to the right position, the thread trimmer cuts the thread, and the first stitch is sewn, which is very beautiful, the tightness is appropriate, and the position is accurate.

The tear opening is complex and irregular, and the suture gun needs to enter from different directions, sometimes the inner opening is easy to enter, and sometimes the outer opening is convenient to enter.

How many stitches to stitch and how to distribute them, Yang Ping had already planned it, and he first stitched a few stitches on the medial mouth; Then move the lens to the inner opening, enter the suture gun from the outer opening, and sew a few stitches on the outer opening.

Each stitch is in place quickly and at one time, very easy and skillful, a total of six stitches, after stitching, horizontal, oblique, radial, flap-shaped, several tears, all stitched.

The meniscus is perfectly put back to its original shape, and when I look at the video after stitching, it seems that it is on a normal meniscus with a few stitches.

Open the water inlet pipe and flush the joint cavity. Then close the water inlet pipe to attract water from the joint cavity and exit the lens. Yang Ping retreated, and Song Zimo did the finishing work.

Dry gauze to dry the water on the surface of the knee joint, disinfect the skin with 75% alcohol, and suture two small openings with one stitch on one side. The cotton pad elastic bandage is compressed and bandaged, the tourniquet is loosened, and the operation is over.

Director Han stared at the screen, and in just ten minutes, the operation was over, and the topic of chat was not opened.

The suture is perfect, a cracked meniscus, looking at the return to its original shape step by step, smooth and neat, the alignment of the wound edge is very neat, there are no wrinkles after suturing, there is an artistic visual enjoyment.

This effect is not a lot of surgical experience, it is impossible to do it at all, to achieve smooth and wrinkle-free, the tension of each needle must be controlled, not the tension of each needle is controlled independently, but several needles must be coordinated to achieve the balance of tension.

"Perfect!" Director Han gave him a thumbs up.

Huang Jiahui was just on the side, she was very nervous all the time, and she silently thought in her heart not to get stuck.

After watching the entire operation, Yang Ping's proficiency in the suture gun, as if the instrument was designed by him, is even more perfect than the company's surgical demonstration video.

I just heard Yang Ping say lightly about the treatment of the stuck gun, it turned out that he had already had a countermeasure, knowing that he had this defect, and he still used his own products, and he couldn't help but feel a little more grateful.

"Teacher Yang, our equipment is still handy, right?" Jia Huicheng asked in fear, and hurried over to help Yang Ping untie the strap behind the surgical gown.

"Yes, very good!"

"Thank you, Mr. Yang!"

"You'll have the equipment and consumables for anterior and posterior cruciate ligament reconstruction on hand." Yang Ping instructed her.

This little girl, last night, hurriedly asked her brother to ask her out, just to tell the flaws of the meniscus suture gun, whether it is really honest or other reasons, at least she is very attentive, and does not treat people who are attentive.

"Okay, I'll send it over right away, along with the materials." Jiahui was excited.

In the surgery center, there are actually some prepared, but since Yang Ping proposed it, Jiahui will definitely not say that the surgery center has it, and she has to ask someone to get it.

Say send it, just send it! Don't leave the trouble to the customer, try to leave the trouble on your side, this is what my brother explained.

"This domestic device is okay, right?" Director Han asked.

Yang Ping said: "Very handy! No worse than the imported ones. ”

"If you need equipment and consumables, please feel free to tell me and do a good job with peace of mind." Director Han is ready to do a good job of guaranteeing the work.

At the end of the operation, the anesthesia subsided, Liang Fatzi's skills became deeper and deeper, Zhang Lin helped the patient to install a knee brace, and Song Zimo gave a pair of crutches to the patient: "Don't bear weight on this leg within six weeks, start rehabilitation training in the afternoon, and the doctor will explain you in detail about the precautions later." ”

The explanation in the operating room only selects the key points, and the patient can't remember it if he says too much.

Xiao Wu captured a few pictures of key nodes in the video system, and then got them on his mobile phone and sent them to Yang Ping and Song Zimo, and Song Zimo and others had to communicate with the patient's family.

At the door of the operating room, the family members were waiting, and when they saw Luo Xiaohu coming out on crutches, his parents immediately came up to help.

"The operation was so fast, just a little bit in?"

Father Luo asked worriedly.

Worried about the operation for a long time, afraid that something is wrong? The operation time is too short, and I am also worried, afraid that it will be sloppy?

Song Zimo showed the picture of his mobile phone: "Dr. Yang is too skilled in this kind of surgery, so it's fast, you see, this is the preoperative meniscus, this is postoperative, the sutures are good, how beautiful!" ”

Luo's father looked at the picture carefully and was very satisfied, the messy crack before the suturing, the flat meniscus after the suture, almost no cracked meniscus, he is not a doctor, but he has an intuitive understanding.

Just like the quality of the wound sutures, the patient can see it even if he doesn't understand it. Stitched, neat, skin fit evenly, beautiful! The stitches are poor, long and short, staggered, the skin is uneven, and it is ugly!

This level was finally passed, and the stone hanging in Luo's father was put down.

Yang Ping sent the picture to Su Nanchen, with a text briefly introducing what he saw during the operation, which was recommended by others, and there should be an echo after the operation.
