Chapter 133 Perfect Stitching

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

Meniscal suture and cruciate ligament reconstruction are the landmark surgeries of knee arthroscopy. Although Director Han is very relieved about Yang Ping, he still needs to go up to see these landmark surgeries to see how powerful Yang Ping's arthroscopic surgeries are.

Huang Jiahui was waiting in the operating room early, waiting for the instrument trolley. She neatly stacked twenty individually sterilized meniscus suture guns on the instrument trolley, and locked the instrument trolley in an out-of-the-way corner.

This corner was the best place she found out after repeated thinking.

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

She used to have enviably long hair, but since she entered this industry, she decisively cut it short enough to be tied.

Today, when she tied her hair up, wrapped it in a net, and then put on a sterile cap, she didn't show a little of it.Training to wear a sterile cap, she practiced countless times in front of the mirror at home until no hair was exposed.

The anesthesia is ready, Song Zimo hangs the patient's X-ray and MRI film on the reading light, instructs Xiao Wu and Zhang Lin to position themselves, and then brushes their hands, disinfects the sheets, and prepares for every detail. They are meticulous.

When Yang Ping washed his hands and came in, everything had been prepared and was just waiting for the show to begin.

While Yang Ping was wearing the surgical gown, Director Han came in.

"Hello, Director!" Everyone greeted.

"Professor Han, hello!" Jiahui greeted Director Han who came in and bowed.

"Hello!" Director Han saw that she was holding a laser pointer in her hand and guarding the sterile boxed instruments, so she knew that the instrument dealer was with the station.

"Which company? New here?"

Director Han had never seen this little girl before.

"Professor Han, I'm new here. I'm from Ruixing Medical, and I manufacture sports medicine products." Jiahui introduced herself.

Director Han picked up a separately packaged meniscus suture gun and looked at it: "Ruixing! The domestic ones should be supported more. This suture gun sometimes jams, so be careful!"

"The connection between the first needle and the second needle is not precise, and sometimes the strength is not well grasped, resulting in an error of 0.5 millimeters. Before the first needle is unloaded, the second needle is eager to enter the propulsion track, resulting in a gun jam. The first After the needle is shot, the trigger cannot be released, the trigger must still be locked, and then go back until it is confirmed that the first needle is off the gun, then release the trigger, and then give the second needle, so that there will be no jamming of the gun. This design needs improvement."

Yang Ping's research on Ruixing's equipment is very in-depth. Before Huang Jiahui reminded him, he already knew about this defect and had a countermeasure, so he just didn't care.

"You are right in researching equipment deeply. Doctors must be proficient in equipment research and cannot rely on the manufacturer's explanation." Director Han appreciated Yang Ping's attitude very much.

"What's the condition of this patient?" Director Han asked while watching the film.

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

"Well! According to the MRI, the meniscus is severely torn, and the suturing technique is difficult. Do it slowly, not in a hurry." Director Han told Yang Ping.

Huang Jiahui moved a stool for Director Han to sit on.

Complete preoperative checks, exsanguination, tourniquet inflation.

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

While speaking, the arthroscopic examination of the knee joint has been completed. The medial meniscus was torn, and no other obvious abnormalities were found. The medial meniscus can be sutured.

Director Han moved to the side of the screen and looked at the video image above: "The tearing is serious, one piece is turned up, fresh tear?"

"It's only been two days since the tear occurred. This is the patient introduced by Su Nanchen, a player of the provincial youth football team." Yang Ping began to insert the needle inside to guide the opening.

After the opening, put the probe in. The probe is the extension of the finger of the arthroscopist. You can further understand the structural lesions and damages by fiddle with and touch.

Yang Ping closed the water inlet pipe, which can reduce the agitation of the running water on the torn meniscus, and used a probe to fiddle with the torn meniscus and smooth it out.Freshly torn, sutured directly, no need to freshen the edge of the tear.

"Sewing gun!"

Xiao Su also did research on the manufacturer's equipment in advance. When Huang Jiahui asked her to take an exam on aseptic knowledge filing, she also asked Huang Jiahui for details of these equipment.

Yang Ping took the suture gun, entered it through the inner port, and began to suture the back corner of the meniscus. The muzzle of the gun was aimed at the planned puncture point, and the trigger was pulled. The needle tip and the thread anchor pierced the meniscus until the attachment of the meniscus was pierced. The joint capsule, the thread riveting is left outside the joint capsule.

He held the trigger tightly and did not let go, pulled back slightly, and the first needle was taken off the gun smoothly. At a distance of 0.5 cm from the first needle, the muzzle of the gun pressed against another planned puncture point of the meniscus, and he pulled the trigger. The second needle went in smoothly, and the gun was withdrawn backward.

When the suture is tightened, the two thread anchors are threaded in longitudinally, and now they are pulled horizontally, and they are fixed behind the joint capsule to become the anchor points of the thread.The knots are prefabricated, irreversible, and can only be tightened, not loosened.

Use the knot pusher to send the thread knot to the proper position, the thread cutter cuts the thread, and the first stitch is finished. It is very beautiful, tight and accurate, and the position is accurate.

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

Yang Ping had already planned how many stitches to suture and how to distribute them. He first sewed up a few stitches at the inner opening;

Each stitch is fast and in place, very easy and skillful, a total of six stitches, after sewing, the horizontal, oblique, radial, petal, and several cracks are all stitched up.

The meniscus was perfectly assembled back to its original shape. Looking at the sutured video, it seemed that a few stitches were stitched on a normal meniscus.

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

Dry the water on the surface of the knee joint with dry gauze, sterilize the skin with 75% alcohol, and suture two small openings, one stitch at each side.Cotton pad elastic bandage is used for pressure dressing, the tourniquet is loosened, and the operation is over.

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

The stitching was perfect. A broken meniscus returned to its original shape step by step. It was smooth and neat.

This kind of effect cannot be achieved without a lot of surgical experience. To be smooth and wrinkle-free, the tension of each stitch must be well controlled. Instead of independently controlling the tension of each stitch, several stitches must be coordinated , to reach a balance of tension.

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

Huang Jiahui was on the sidelines just now, and she was very nervous all the time, thinking to herself not to get stuck.

After watching the whole operation process, Yang Ping's proficiency in the suture gun, as if the device was designed by him, was more perfect than the company's operation demonstration video.

Just now I heard Yang Ping casually say how to deal with the jammed gun. It turns out that he already has a countermeasure. He knows this defect and still uses his own product. I can't help feeling a little more grateful.

"Ms. Yang, are our instruments still available?" Jiahui asked in trepidation, and hurried over to help Yang Ping untie the strap behind the surgical gown.

"Good, very good!"

"Thank you Teacher Yang!"

"You also prepare the equipment and consumables for the reconstruction of the anterior and posterior cruciate ligaments." Yang Ping instructed her.

This little girl hurriedly asked her elder brother to ask her out last night just to tell about the defects of the meniscus suturing gun. Whether it is really honest or for other reasons, at least she is very hardworking and does not treat people who are hardworking.

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

In the surgery center, some were actually prepared, but since Yang Ping brought it up, Jiahui definitely wouldn't say that the surgery center had it and asked others to get it.

Say send it over, send it over!Don't leave the trouble to the customer, try to keep the trouble on your own side, this is what my brother told me.

"Is this domestic equipment okay?" Director Han asked.

Yang Ping said: "It's very smooth! It's no worse than imported ones."

"If there is a need for equipment and consumables, please tell me at any time, so that you can complete the operation with peace of mind." Director Han always takes care of the security work.

After the operation, the effect of anesthesia subsided, Fatty Liang's skill became more and more powerful, Zhang Lin helped the patient install a knee brace, and Song Zimo put a pair of crutches on the patient: "Do not bear weight on this leg for six weeks, and start to recover in the afternoon Training, the doctor will explain to you in detail the following precautions."

The explanations in the operating room only focus on the key points, and the patient can't remember too much.

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

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

"The operation is so fast, why did you just go in for a while?"

Father Luo asked worriedly.

Worried about the long operation time, maybe something went wrong?The operation time is too short, and I am also worried. I am afraid that it is done sloppy?

Song Zimo showed the picture on his phone: "Dr. Yang is very proficient in this kind of operation, so hurry up. Look, this is the meniscus before the operation, and this is the one after the operation. It is sutured, so beautiful!"

Luo's father read the pictures carefully and was very satisfied. The messy tear before suturing, and the meniscus was flat and intact after suturing. It is almost impossible to see that the meniscus is cracked. He is not a doctor, but he has an intuitive understanding.

Just like the quality of wound sutures, patients can tell even if they don't understand it.The stitching is good, neat, the skin is flat, beautiful!Poor stitching, long and short, crooked, uneven skin alignment, ugly!
This level was finally passed, and Luo's father let go of the stone hanging in his heart.

Yang Ping sent the pictures to Su Nanchen, with a brief description of what he saw during the operation, and he was recommended by others, and he will hear back after the operation.
