Chapter 488 Combination of soft and hard, laparoscopic clinical

After the unhealthy trends in the equipment department were brutally suppressed, everyone became much better, and Wang Dali was no exception.

Everyone turned stress into chicken blood and put all their energy into work.

For the ultrasonic knife, after the transducer is done, there are many other tasks.

Especially the cutter head, because it is a detachable disposable consumable, it should be selected according to the anatomical needs of different departments. There are more than a dozen types.

The shape of the scissor head is straight, curved, and the length and thickness are also different, which are divided into different models.

There is also an extension hose that can be connected with a matching knife head for digestive tract surgery under the hose endoscope.

At the same time, in order to better help clinical cost control, it is necessary to continue to improve the algorithm, and accurately output energy according to the state of blood vessels and tissues held by the cutter head, so as to make the operation more precise and the efficiency of cutting and coagulation higher.

Since Sanqing has always had the habit of producing portable instruments, Wang Dali even designed a portable wireless ultrasonic scalpel with a new transducer.

Not only is it easier to replace the cutter head, but the battery pack can also be reused, which greatly improves the convenience of the surgical tool.

It's just that this portable ultrasonic knife cannot output for a long time due to the limited battery capacity, but it is enough for more than ten minutes of cutting and hemostasis.

In this way, a powerful family member has been added to the first aid kit, completely completing the entire medical first aid puzzle.

In the future, doctors can directly use the ultrasonic scalpel to perform some simple minimally invasive operations in the field, in emergency vehicles, or in disaster relief situations.

When everyone was busy with the ultrasonic scalpel, the product registration certificate of the rigid tube endoscope came down.

Because these products are relatively mature, they are listed on the product catalog exempt from clinical trials, that is to say, they can be officially launched for sale.

However, Weikang was not in a hurry to sell, but first selected five sets of high-definition and 4K samples, and sent them to the No. 1 civilian hospital in Kunming for clinical use.

He is waiting for the development of the ultrasonic scalpel and the insufflation machine, and plans to wait for a complete set of laparoscopic surgery plans to come out before launching them together.

Because endoscopes, whether they are flexible tubes or hard tubes, are all self-developed products of Sanqing, and compared with Olympus La, the advantages are not obvious.

Only by joining the ultrasonic scalpel with high black technology content and becoming an overall solution provider for minimally invasive surgery can we completely widen the gap and seize the market.

Therefore, after the hard tube endoscope is ready, the tube endoscope project will start immediately.

In comparison, soft mirrors are more difficult than hard mirrors, because it is not only a problem of imaging technology, but also involves mechanical processes.

Whether it is the esophagus or the intestines, the diameter is limited, and the part of the hose that extends into the human body cannot be too thick.

If it is too thick, the patient will feel uncomfortable.

Of course, it should not be too thin, otherwise the viewing angle will be easily restricted, and it will be difficult for doctors to operate.

Most of the hose endoscopes now have the most common specifications with a diameter of 1 cm and 4 mm, which are suitable for the stomach, throat, nasal cavity, bladder and urethra.

The soft mirrors used by young children are thinner, with a diameter of about 2.7 mm.

Don't look at the diameter of 1 cm, it looks a bit thick, but there are a lot of things to put inside.

A small piece of hose, there must be a steel wire mesh for support, a water pipe for washing the lens, an optical fiber bundle for light guiding, a control cable for controlling the direction of the front lens, and finally a small pliers , can easily cut off polyps.

A one-centimeter-thick tube, with so many things stuffed inside, can it not be crowded?
The various parts have to be so small, but the precision is so high, which greatly tests the mechanical technology, and the requirements for the processing plant will be very high.

Fortunately, with the rapid promotion of aerospace, semiconductor and other industries, the domestic high-end parts precision processing industry has also been vigorously developed. Suzhou Province is also a famous manufacturing province. As long as they are willing to spend money, they can still find suppliers that meet the requirements.

******
No.1 People's Hospital in Kunming City.

Peng Hai came here again for door-to-door service.

This time, there was something wrong with the electronic gastroenteroscope, and the hospital called the company directly to ask someone to come to repair it.

So he was sent by the speed of light, and with him was Xiao Zhang, a representative of Mindray's equipment.

Because the product always has small problems, the doctors complained a lot, so the company sent Xiao Zhang to appease the customer, and at the same time inquire about the recent purchase news of the hospital.

The job of a medical device representative is actually very difficult. He travels around various hospitals for more than half of a month, making friends with department directors, device chiefs, deans and others, and asking if there is any plan to purchase equipment.

Things sound simple, but it is difficult to do.

No one knew if the director was in the office when he went to the hospital.

Even in the office, it is possible that he quarreled with his wife today, and he was not in a good mood, so he closed the door and thanked the guests.

Even if he was lucky enough to meet him happy today and entered the office, he might get bad news. He came a step late and the hospital only bought a few pieces of equipment.

The service life of large medical equipment is very long. If the hospital does not expand its capacity on a large scale, it will not purchase new equipment within five years.

Therefore, it is very important information to know which equipment the hospital is going to purchase.

The two came to the outpatient building and went straight to the gastroenteroscopy room.

As soon as I went in, I found that there was only one person inside, and no one else was there.

"Hello, Doctor He..." Peng Hai had just greeted him when he was roughly interrupted by the other party.

"Xiao Peng, you came just in time, just in time to fix it, why is your equipment always malfunctioning." Dr. He said with a frown, with an unhappy expression on his face.

When Peng Hai was about to speak, Xiao Zhang gave him a look and greeted him with a smile on his face.

"Doctor He, it's me, Xiao Zhang from Mindray, long time no see, you are getting more and more energetic, why don't you let Peng Hai check the equipment first to see what's the problem."

Doctor He waved his hand, and Peng Hai walked two quick steps as if he had been pardoned, to check the equipment in the corner.

Xiao Zhang is very experienced, and after a few apologies, Dr. He's face was not so ugly.

"By the way, where is Director Zhu? Is he busy recently? Is he in the office today?" Xiao Zhang began to inquire about the director's whereabouts.

Dr. He glanced at him: "Why, do you still want to sell equipment to Director Zhu?"

Xiao Zhang immediately lifted his spirits: "Dr. He, have you heard any news about procurement?"

Dr. He shook his head: "I don't know anything, but our hospital probably has no shortage of equipment. Every time Sanqing has new equipment, the first samples will be sent here."

Xiao Zhang showed a faint smile: "Sanqing's equipment is naturally good, and the capsule gastroenteroscope has a good reputation, but they have just entered the industry and do not have many equipment. Our Mindray products are relatively complete and have everything. What do you think? "

Dr. He chuckled: "Not before, but it doesn't mean there won't be any in the future. Two days ago, Sanqing sent a batch of medical laparoscopes. We have performed several operations, and the results are very good."

Alarm bells were ringing in Xiao Zhang's heart, and he hurriedly asked, "Didn't I hear that Sony stopped supplying Sanqing? How could they still manufacture equipment?"

Dr. He proudly said: "You don't know that, it is said that you are looking for a domestic imaging chip."

Xiao Zhang's eyes widened: "Can this domestic chip work well? They should be mid-to-low-end products, without 4K imaging, right?"

"There are high-end endoscopes with 4K imaging and mid-end endoscopes with ordinary 1080p imaging, and the results are very good."

When Dr. He mentioned Sanqing's medical equipment, a smile appeared on his face, and he was full of praise.

"Even the director is boasting that the imaging is no worse than Olympus' high-end endoscopic imaging."

"Even the 1080P model has exceptionally clear images. I had an appendicitis operation yesterday, and I directly adjusted to the highest 2K setting. After 30 minutes of surgery, the field of vision was very clear, and there was no fever problem."

"It seems that after the Sanqing, domestic production is really going to rise."

Xiao Zhang felt sour in his heart, laughed dryly a few times, and quickly changed the subject: "Why isn't Dr. Huang here? Are there other people?"

Dr. He pointed to the door: "I've all gone to the laparoscopic operating room, where surgery is being performed."

Xiao Zhang was at a loss: "Is it a teaching operation? Why are so many people going?"

"No, didn't Sanqing's laparoscopy just arrived, and the director saw that Lie Xinxi was doing gastric perforation surgery."

"As for Lao Huang, they all went to watch."

"Then why don't you go?" Xiao Zhang asked with some doubts.

Dr. He pursed his lips tightly, with a look of pain on his face: "After two consecutive days of appendicitis surgery, I vomited. I need to take a break and take a good rest."

Xiao Zhang rolled his eyes and said, "Then I'll go to the stage to watch and see how useful Sanqing's laparoscope is."

Dr. He looked at Xiao Zhang's badge. This is a formal medical salesman with a certificate. He usually comes to the department to hang out when he has nothing to do. He knows everyone well. He has no reason to refuse.

So I brought a white coat, put it on Xiao Zhang, and took him to the laparoscopic operating room.

After disinfecting and washing hands, I found that there were many people around the operating table, all of whom were surgeons, but most of them were outsiders.

The patient was lying on the operating table with a hole in his navel, and Director Zhu was concentrating on the operation.

Xiao Zhang said with a smile: "Single-port laparoscopic surgery is very difficult, no wonder Director Zhu is the one who performs the surgery himself."

Director Zhu coughed lightly and said, "Xiao Zhang is here."

Xiao Zhang looked as happy as seeing his own father, and hurried over, took a few glances, and immediately exclaimed.

"Director, your unique skill is really amazing. It looks like a visual feast. I dare say that even the general surgery director of Haishi Ruiji Hospital is not as smooth as you."

Director Zhu didn't respond, and he was still performing the operation in an orderly manner.

Xiao Zhang's praises are endless, as if he doesn't want money.

"Director, your operation is not a medical skill, but an art. I can't bear to blink when I see it, for fear of missing any wonderful moment, and it will be a big loss."

"Your movements are too fast. My eyes are blurred and I can't keep up with your rhythm. How can you be so powerful?"

"I heard that you showed extraordinary talent in surgery when you were in kindergarten. A boss like you should really write an autobiography. It will definitely be a great inspiration to young people. At least I really want to read it."

"Your blood loss is so well controlled every time, and it has never exceeded 50 milliliters. I really don't know how you did it!"

Not far away, Dr. He heard these exaggerated flattery, the corner of his mouth twitched, and he secretly rolled his eyes.

"The medical representative is really thick-skinned. He is simply talking nonsense. The simplest operation of gastric perforation repair can only be done with hands. He just exaggerated the difficulty of a heart transplant."

Here, Xiao Zhang kept exaggerating with his mouth, but his eyes were on the operation screen on the screen.

Sure enough, the pixels were extremely clear, and on the 55-inch large screen, there was blood dripping and bright red.

Not only was it flesh and blood, but it was still wriggling slowly, as if the patient had been disemboweled right in front of him.

This scene brought a huge impact in an instant, no less than an open operation.

Even though he was experienced in many battles and often haunted the operating room, seeing such a large ultra-clear screen, he still couldn't restrain his stomach from moving.

After watching for a while, his stomach was churning faintly, so he had to shut his mouth.

Wanting to look away, but reluctant to observe the competing products at close range, he could only keep his mouth shut and watch the endoscopic surgery on the screen seriously.

Fortunately, his flattering performance for the first few minutes was very effective. Even if he is silent now, it doesn't affect Director Zhu's good mood.

In fact, endoscopic surgery is quite gentle. After all, the field of view shown is limited, and only a part of the internal organs can be seen.

If it is an open operation, it involves bleeding and suction, and the fresh and tender internal organs are exposed, the impact on people will be even greater.

Xiao Zhang reacted so violently mainly because the screen was too big, the images were too clear, and the colors were very bright.

He deliberately got too close, making it look very menacing, bloody, and I felt particularly unbearable.

However, the surgeons next to each other looked at the operation screen with a calm face, and discussed it from time to time, and the atmosphere was very enthusiastic.

Xiao Zhang stared at the picture and kept comparing it with his own product in his mind. He was surprised to find that his own product was a complete failure in terms of picture texture, color and clarity.

His heart sank. If this is the case, the endoscope may not be easy to sell.

If it is Olympus, you can also emphasize localization.

But Sanqing, like Mindray, is both domestically produced equipment, and this advantage has been lost.

"Hmph, I don't believe Sanqing's endoscopes are better than Olympus's."

He tried his best to keep the operation performance of Sanqing endoscope in mind, and planned to find a sample from Olympus in other hospitals for comparison.

Xiao Zhang and the others came late, and when they entered the operating room, the operation had already entered the second half.

So after half an hour, the operation ended smoothly.

Director Zhu finished typing, put down the instrument in his hand contentedly, and asked around, "What do you think?"

At this time, Xiao Zhang's stomach had recovered a little, and he immediately clapped his hands.

"Oh my god, Director, your surgery looks like a top pianist's performance, full of artistic sense, I can't wait to watch it for another two hours."

Director Zhu's face was sullen, with a slightly embarrassed expression: "I'm asking about new endoscopy equipment."

Only then did the other doctors speak one after another, talking in a hurry, mostly in praise.

Director Zhu nodded in satisfaction, and walked towards the door of the operating room.

"Let's go, what's the matter, go to my office and talk about it."

Xiao Zhang quickly followed, came to the director's office, and was about to speak.

Director Zhu waved his hand and interrupted him: "I know what you mean by coming, it's not that you don't want to support your company, but to be honest, your company's equipment keeps having problems, and I want to complain to you, Mr. Li. "

Xiao Zhang laughed dryly and said something nice, but Director Zhu didn't let go.

In the end, Director Zhu made a final decision and said, "How about this, we now have samples from Sanqing for endoscopes, and the hospital has no procurement plan for the time being. I will let you know when there is news."

"As for other equipment, the feedback from other departments is okay, as long as you can convince them, I have no opinion."

Xiao Zhang knew that there was nothing he could do, and he wanted to make a long-term plan, so he could only return bitterly.

Within a few days, the news of Sanqing's successful development of rigid tube endoscopes spread throughout the industry.

Even Olympus was alarmed.
