During arthroscopic surgery, the anchor suture is easy to tangleunable to fix the soft tissue using conventional one lumen cannula. Thus we design a novel “Double lumen cannula” containing a flexible septum inside the cannula which can separatechange the cannula volume dynamically into two lumen. This would decrease the surgical timesoft tissue injury,improve the security of su

The AR-assisted endoscopic navigation system for brain surgery combines CT/MRI images, 3D cerebrovascular/nerve models,endoscopic images for surgical planningnavigation. AR glasses can display the 3D navigation inside the patient＇s skull, providing surgeons with intuitive 3D surgical navigation. In addition, the cerebrovascular/nerve model is also superimposed on the endoscopic image, allowing the surgeon to predict the upcoming surgical situation. The AR display endoscopic images can be simultaneously transmitted to the remote site for assistance through 5G communication.
