Chapter 383: Pacemaker
Li Zhengping's pathological examination report explained: "The pathological results over there showed idiopathic mesenteritis in the small intestine, with chronic inflammatory cell infiltration dominated by lymphocytes and plasma cells, fat necrosis, foam, and multinucleated macrophages." cellular response and extensive fibroblast, collagen fiber proliferation."
"The hyperplasia caused by enteritis." Liang Yi replied.
"I asked the director of the pathology department that this is not common, no wonder it looks weird."
"The other is the formation of small multilocular abscesses, mesenteric lymphoid reactive hyperplasia, lesion involving the outer muscular layer of the small intestine to form a tumor-like mass, local incomplete mechanical obstruction of the small intestine, high degree of submucosa edema, lymphatic vessel dilation, and hyperemia of the serosa layer and fibrinous inflammation."
Liang Yi took the report and looked at it carefully, saying: "Pathological examination is simply the nanotechnology in medicine."
"That's right, our surgeons do rough work, and others do fine work, which is clearly divided." Li Zhengping said.
Seeing the two of them talking, Xie Tianmu paced outside for a while but didn't go in.
After Li Zhengping left the office, Xie Tianmu came in with a straight face, adjusted his glasses, glanced down at Liang Yi's schedule, and said, "You young people do things slower than us old people."
Liang Yi said, "Is the director in a hurry to use it?"
"That's not true, I just can't understand how half-hearted you are doing things." Xie Tianmu said.
Liang Yi didn't dare to speak anymore, and hurriedly continued to finish the work at hand.
Xie Tianmu said: "The technicians from the source power pacemaker manufacturer will come over later, you go and listen to it with other doctors. You don't need to understand the principle of this very professional thing, but how to use it, what are the indications and Contraindications must be clarified, understand?"
This is the same as medicine used by physicians. Clinicians do not necessarily know the chemical structure of the drug, but they must know the indications and contraindications of the drug.
"Okay..." Liang Yi nodded in agreement.
This is to allow myself to participate in emergency cardiac surgery in the future. I have to ask the technicians from the source power pacemaker manufacturer to come over.
At around ten o'clock in the morning, the technicians from the manufacturer came over with their company's products.
All the doctors and nurses in the department were gathered around the doctor's desk. The originally small desk was packed to the brim, and advanced students, trainees, and interns could only stand in the corner.
The technician took out the VR projector, Liang Yi took a look, and saw the HJ brand icon. Isn’t this the VR projector developed by Junhao before? Looking at the effect projected by the technician, it should be a low-configuration projector. It has not reached the projection effect of the product that Li Junhao gave him before.
The technician briefly introduced the working principle of the pacemaker, which is actually not difficult to understand.
The artificial cardiac pacing system is similar, mainly including two parts, the pulse generator and the electrode lead.The pulse generator alone is often referred to as a pacemaker.In addition to the above-mentioned pacing functions, the pacing system also has the sensing function of transmitting the heart's own electrocardiographic activity back to the pulse generator.
The product technician introduced: "The main battery of the pacemaker is different from other manufacturers. Our company uses the latest research and development of lithium-iodine battery and electronic circuit process, which can generate and output electrical pulses. It is more powerful than other similar products in the past. The product has higher stability and battery life, and the conductive metal wire wrapped in an insulating layer outside the electrode wire, its function is to transmit the electrical pulse of the pacemaker to the heart, and transmit the intracavity electrogram of the heart to the perception of the pacemaker For the circuit, I use a polymer insulating layer and graphene technology metal wire, which has excellent insulation on the outside and first-class conductivity on the inside.”
Then he used two or three PPTs to introduce how they learned about German technology,
When it comes to those high-tech things, the doctors and nurses don't understand anything, they only know that this product is awesome, buy it!
Xie Tianmu also nodded, to enhance the atmosphere, said: "Yuanli is indeed one of the best pacemaker manufacturers in China. From this point of view, the quality of their products is still guaranteed in this aspect."
Sure enough, every technician is an eloquent sales expert. It is secondary for them to introduce how to use the product, but mainly to promote the advantages of their products. As for the shortcomings and shortcomings, they will generally mention them in one stroke.
The technician continued: "The dual-chamber pacemaker I brought over today can be adjusted to DDD mode, also known as atrioventricular omnipotent pacing. It has atrioventricular dual-chamber sequential pacing, atrial Physiological pacing mode with double response and inhibition. VDD mode is also called atrial synchronous ventricular inhibitory pacemaker. Both the atrium and the ventricle have sensing function, but only the ventricle has the pacing function. In the entire VDD pacing system, Proper perception of the P wave is key to its proper functioning."
Xie Tianmu grinned and said, "We are all idiots when it comes to products. To put it bluntly, you don't need to tell us how to raise pigs. You just need to tell us how to make the pork taste better when you buy it."
The technician smiled awkwardly, and quickly cheered the director, saying: "Our director Xie is really humorous, so I will talk about how our products are used in clinical practice. In fact, we have made a lot of innovations in products, but in order to let surgical teachers can quickly To adapt to our products, our product usage methods are similar to those in the world.” He opened a new PPT.
At this time, the doctors and nurses all took out their notebooks. Those just now are all false, and this kind of clinical operation introduction is real. If you miss it, it will be very troublesome to ask others later. Feel free to come across clinical knowledge. Medical staff all firmly believe that a good memory is not as good as a bad pen. Now that there are mobile phones that can take videos, everyone is still used to taking notes.
The technician explained: "Our product is to insert the electrode lead from the vein under the arm or the clavicle, insert it into the predetermined cardiac chamber pacing position under X-ray fluoroscopy, fix it and detect it. Then embed the electrode wire in the chest The pacemaker is connected by wires, the skin is sutured, and the operation can be completed. I will talk about it briefly, and I believe that you clinicians are more familiar and professional than me.”
Xie Tianmu looked at it, stroked his train of thought, and asked, "Is that all?"
The technician nodded and smiled, "Yes."
Seeing that the technician finished talking about the product, Xie Tianmu got up and said, "Since the engineer has finished talking, think about what's wrong."
Zhong Yubo turned his pen around, stood up and asked, "The battery life is ten years, right? Is there anything I should pay attention to after surgery?"
