[Spectacle frames] Looking at 3D movies requires wearing dedicated 3D glasses. Now doctors also need to wear 3D glasses for surgery. Why is this? It turns out that this is the latest 3D laparoscopic surgery. By using 3D glasses, doctors can have an immersive three-dimensional feeling, which is more conducive to surgery and avoids trauma. Yesterday, the gynaecologist of Huangdao District of the Affiliated Hospital of Qingda University performed a 3D operation to remove the uterus from an endometrial precancerous lesion.
The 50-year-old Zheng Wei (a pseudonym) had a bloody nose that began to bleed a year ago. Recently, the gynecological examination at the Huangdao Affiliated Hospital of Qingdao University was diagnosed as an endometrial precancerous lesion. "Considering that the patient has no need for childbirth, we decided to remove the patient's uterus." Yao Qin, deputy director of the Department of Gynaecology at Huangdao District of Qingdao Affiliated Hospital, told reporters that in accordance with the traditional surgery requires open surgery, the patient's trauma, even if it is Minimally invasive surgery is also easy to cause trauma to patients. After consultation, yesterday, Dai Shuzheng, Emeritus Director of the Department of Gynaecology of the College of Health Sciences, and Yao Qin, deputy director of Huangdao District gynecology, performed the latest 3D laparoscopic surgery on patients. "This is a new technology we have just used, which can reduce the damage to the patient's organs and help the wound heal." Yao Qin said.
During the operation, the doctor punched four holes in Zheng’s abdomen. Each hole was about the same size as the keyhole. After the operation began, the medical staff put on special 3D glasses. "We use a special 3D laparoscope. It enters the patient's body and captures 3D images. Therefore, only by wearing 3D glasses can we see clearly." Yao Qin said, wearing glasses, immediately have a three-dimensional sense, can clearly see To the patient's lesion location, the operation is more convenient.
The stereoscopic image is more convenient for surgically emerging 3D laparoscopic surgery. It uses the principle of polarized light to generate stereoscopic images in real time, enabling the operator to have stereoscopic orientation when operating the instrument. In fact, the laparoscopic lens used in the patient consists of two small lenses that are very close to each other, each taking pictures of the cavity, and then the two angles of the images are simultaneously displayed by the respective display devices, so that there are two nuanced images. The image is displayed on the display at the same time. At this time, if you look directly with your eyes, the pictures you see are overlapping and unclear. The use of polarized glasses to watch, the left eye can only see the left camera shooting screen, the right eye can only see the right camera shooting screen, so that together will see a three-dimensional image, the image on the screen becomes immediately clear And the hierarchy is clear.
