The three-dimensional landscape is more intuitive. The endoscopist uses the three-dimensional image feedback to the brain without needing too many layers of thinking, and can make fine adjustments directly.
I'm afraid the interventional surgeon's brain circuit needs to be longer, and fluoroscopy cannot achieve three-dimensional fluoroscopy. 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 actual picture and can only be used as a reference for doctors. It can be said that interventional surgery is equivalent to semi-blind insertion, and the three-dimensional visual field of vision cannot only be based on two-dimensional images. It's just better than ordinary blind medical operations. There is finally a picture for reference, even 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.
Interventional surgery can do things that endoscopic surgery cannot do. For example, in an endoscope, the camera walks 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 body tubes is too small and the length is too long, and the endoscope cannot meet the required fine diameter and ultra-long length. In this case, interventional surgery X-ray systems can only be used. This issue was discussed during the last bronchoscopy. The human cardiovascular system is also extremely long and small in diameter, so surgeries like PCI require an X-ray system rather than an endoscope.
Is there any surgery that combines endoscopic and x-ray systems? Yes, ercp is endoscopic retrograde cholangiopancreatography. The duodenoscope is inserted into the digestive tract through the mouth to find the duodenum **, and then a contrast catheter is inserted to inject a contrast agent and an x-ray film is taken to display the pancreatic bile duct. It was an interventional surgery performed in the interventional room. The prerequisites are the same, the pipe cannot be too long, thin or complicated.
It is possible to perform thoracoscopic coronary artery bypass grafting, but like traditional surgery, it is not a technique for doctors to solve the cause of the disease through the path in the human body. It is different from the above two. Thoracoscopy is the same as laparoscopy. If the risk is too high, it needs to be converted to thoracotomy.
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 question 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. Just because she is a little 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 only saw things, and she almost shuddered in her heart.
Fu Xinheng, who was asking her questions, glanced at every expression on her face like a second hand. His harshness would 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.
