The three-dimensional landscape is more intuitive. The endoscopist feeds back to the brain through the three-dimensional image and does not require too many layers of thinking. He can directly make fine adjustments manually.
I am afraid that the brain circuit of the interventional surgeon needs to be longer, and fluoroscopy cannot achieve three-dimensional perspective. The three-dimensional image produced by the computer system of the angiography machine is an image reconstructed by a computer. It is not a three-dimensional image of the real picture. It can only provide
The doctor serves as a reference. It can be said that interventional surgery is equivalent to semi-blind surgery. The three-dimensional visual field of view cannot only be based on two-dimensional images. It is just better than ordinary blind medical operations. There is finally a picture for reference, even if it is 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.
There are things that endoscopic surgery cannot do, such as interventional surgery. For example, an endoscope uses a camera to walk inside the lumen, and it is impossible to judge the direction of the pipeline as a whole from the outside.
The diameter of some human tubes is too small and too long, and the endoscope cannot meet the required fine diameter and ultra-long length. At this time, the only way to use the interventional surgery X-ray system is to use the interventional surgery X-ray system. This problem was already discussed last time during bronchoscopy. The heart of the human body
The vascular system is also extremely long and small in diameter, so surgeries such as PCI require an X-ray system rather than an endoscope.
Is there any surgery that combines endoscopic and
The catheter is injected with contrast agent and an X-ray film is taken to show the pancreatic and bile ducts. This is an interventional surgery performed in the interventional room. The prerequisites are the same, the duct cannot be too long, thin or complicated.
Thoracoscopic coronary artery bypass grafting can be done, but like traditional surgery, it is not a technique that doctors use to solve the cause of the disease through the path in the human body. It is different from the above two. Thoracoscopy and laparoscopy are the same. The risks are too high and need to be transferred.
Open the chest.
At this point in the technical analysis, in fact, the most important factor in any operation is not the instrument but the surgeon. The deficiencies of the instrument must be made up for by the doctor's own technical level, just like endoscopic surgery in the evening.
Faced with the questions raised by her senior brother, Xie Wanying just looked back silently.
Looking into her big eyes as clear as a bright stream, Yu Xuexian's heart skipped a beat.
The conclusion he made was based on common sense and might not be valid for her. It was just because she was a bit special.
Think about it, when she was in the hospital outside the liver and gallbladder, she had no endoscope or X-ray system, but she and Song Xuelin still performed the blind operation successfully.
The biggest issue now is not about technology, it is——
"Do you think you can do it alone without Dr. Song?"
This voice did not belong to Senior Brother Yu. Xie Wanying turned around, and her eyes inadvertently collided with the cold, ruthless black eyes opposite her, which looked only at things, and she almost shuddered in her heart.
Fu Xinheng, who asked her, looked at every expression on her face like a second hand, and his harshness definitely did not let go of anyone's innermost thoughts on academic issues.
As long as there is a little bit of uncertainty about technology, his cold eyes can accurately catch it.
Xie Wanying cautiously shut her mouth first.
Mr. Fu is not someone else. He only talks about technology with you, and all he talks about is hard currency, so you can't say a word of nonsense.
