Chapter 1388 [1388] Tortured

The three-dimensional landscape is more intuitive. The endoscopist feeds back the brain through the three-dimensional picture without too many layers of thinking, and can directly make fine adjustments by hand.

The brain circuit of interventional surgery doctors may need to be longer, and perspective cannot achieve three-dimensional perspective. The three-dimensional images produced by the computer system of the angiography machine belong to the images reconstructed by the computer, not the three-dimensional images of the real pictures, and can only be used as a reference for doctors. It can be said that interventional surgery is equivalent to semi-blind insertion, and there is no three-dimensional visual field of view, only two-dimensional images can be used. It’s just better than ordinary blind medical operations. Finally, there is a picture for reference, even if it’s a two-dimensional picture, which means that if an error occurs, the recovery time can be greatly shortened and timely adjustments can be made.

It cannot be said that interventional surgery is definitely inferior to endoscopic surgery. Both have their own advantages and disadvantages.

Like interventional surgery, there are things that endoscopic surgery cannot do. For example, in endoscopy, the camera walks in the lumen, and it is impossible to judge the direction of the pipeline from the outside.

In some human bodies, the diameter of the pipeline is too small and the length is too long, and the endoscope cannot meet the required fine diameter and ultra-long length. At this time, the X-ray system for interventional surgery can only be used. This problem has already been mentioned in the last bronchoscopy. The human cardiovascular system is also extremely long and small in diameter, so procedures like PCI require an x-ray system rather than an endoscope.

Is there a combination of endoscopic and x-ray systems? Yes, ercp is endoscopic retrograde cholangiopancreatography. A duodenoscope is inserted through the mouth into the digestive tract to find the duodenal papilla, and then a contrast catheter is inserted into the contrast medium to take x-rays to show the pancreaticobiliary duct. It is an interventional operation performed in the interventional room. The prerequisites are the same, the pipeline cannot be too long, too thin or too intricate.

It is possible to do thoracoscopic coronary artery bypass grafting, but like traditional surgery, it is not a technique for doctors to solve the cause of disease from this path in the human body, and it is different from the above two. Thoracotomy is the same as laparoscopy, if the risk is too high, the chest needs to be turned open.

From the technical analysis to this point, in fact, the most important thing for any operation is not the instrument but the surgeon. The defects of the instrument must be made up by the doctor's own technical level, just like endoscopic surgery in the evening.

Facing the question raised by her senior brother, Xie Wanying just looked back silently.

Yu Xuexian's heart skipped a beat when he saw her big eyes that were as clear as bright streams.

The conclusion he made was based on common sense, and it may not be true for her. Just because she is a bit special.

Think about when she was outside the liver and gallbladder, she had no endoscope and no X-ray system, and she succeeded in blind operation with Song Xuelin.

The biggest problem now is not the technology, but——

"Do you think that Dr. Song is not here, so you can do it alone?"

This voice does not belong to Senior Brother. Xie Wanying turned around, her eyes inadvertently collided with those cold, ruthless black eyes that only had things in her eyes, her heart almost trembled.

Fu Xinheng, who asked her questions, glanced at the slightest expression on her face like a second hand, and his harshness would never let go of even the slightest wavering in anyone's heart on academic issues.

As long as there is a little bit of uncertainty about technology, it can be accurately caught by his cold eyes.

Xie Wanying cautiously shut her mouth first.

Mr. Fu is no one else, he only talks about technology with you, and what he talks about is hard currency, so you can't say a word of nonsense.
