Dr. Zhang Qiang uses virtual reality technology to assist varicose vein surgery

On December 20th, Zhang Qiang announced through his personal Weibo that Dr. Zhang Qiang successfully completed the VR assisted varicose vein surgery in Beijing. During surgery, the concentration of lidocaine (a local anesthetic commonly used in medical clinics) was reduced to 0.25%, which is 1/4 of the conventional concentration (1%), and the patient's heart rate and blood pressure were stable with no significant pain. After the patient's smooth recovery, the results of the press conference will be held.

At the same time, Zhang Qiang said that after applying VR to patients with varicose vein surgery, the patient can go home about 1 hour after surgery, which greatly relieves the patient's body pain and psychological anxiety.

According to reports, the VR scene applied by Dr. Zhang Qiang to patients is based on Zhang Qiang's dream. He intends to name it “Smile's Dream” (Smile is the English name of Dr. Zhang Qiang), and the dream is like this:

The people gently wandered in the air two or three meters above the ground, starting from the misty wilderness and entering the lush forest. I have seen the birds and flowers of spring, and I have experienced the coolness of the summer breeze. I can see the autumn leaves returning to the roots, and I can hear the tranquility of the winter snow. In this way, in the reincarnation and change of the four seasons of spring, summer, autumn and winter, feel the coziness and comfort blended with beautiful nature.

Zhang Qiang said: "These virtual images are completely 360° stereoscopic. The falling leaves, the flying butterflies, and the natural sounds mixed in the light music are all specially made, even including how to overcome the vertigo brought by the VR, etc., we all do A lot of considerations." Dr. Zhang Qiang said that when the doctor's surgery for the patient is completed, the VR scene that the patient sees will just end.

According to Zhang Qiang Weibo, on December 19, Zhang Qiang made the first VR-assisted local anesthesia operation in Shanghai, but Zhang Qiang said frankly that the operation was not very smooth. The VR technique showed small twists and turns during the operation: VR The glasses appear foggy, the patient can't see the picture; the patient sees the angle of view and the angle of view that sits or stands and is inconsistent, but these problems are solved one by one in Beijing.

Zhang Qiang said that this is likely to be the first two cases in the world and the only two cases of VR-assisted local varicose vein surgery. Moreover, the VR products used in these two surgical applications are led by the team of Dr. Zhang Qiang, and it is also the first VR product in China that is led by the doctor team. This is just the beginning.
