Laparoscopic technique is a landmark reform in the history of surgery. Various wired connections of traditional laparoscopy has some disadvantages such as restricting the movement of laparoscope, hindering intraoperative manipulation, potentially contaminating operation area and causing safety accidents. So our team has spent five years developing a wireless ultra-high-definition endoscopic system for the first time, and introduce the characteristics of this system and simulation application results.

This wireless ultra-high-definition endoscopic system integrates the camera cable and light source cable, and wirelessly transmits intraoperative images to the ultra-high-definition monitor, mobile phone terminal and cloud platform with ultra-low delay. Thirty doctors used this wireless ultra-high-definition endoscopic system and a traditional domestic wired high-definition laparoscopic system to complete basic laparoscopic operations such as bean picking test and paper cutting test. After that, this two systems were evaluated in definition (1-5 scores, 5 scores= very clear, 1 score=very unclear), ergonomics (1-5 scores, 5 scores=very comfortable, 1 score=very uncomfortable) and image delay (with or without).

Based on iso12233 standard test card, the image definition of wireless endoscopy was higher than that of wired laparoscopy. The mean score of image definition of wireless endoscopy was also higher than that of wired laparoscopy [(4.8±0.4) vs (4.5±0.5), P=0.029]. The mean score on ergonomics of wireless endoscopy was higher than that of wired laparoscopy [(4.6±0.7) vs (3.0±0.7), P<0.001]. There was no difference in the image delay between this two systems (P=0.99).

There are various advantages of this wireless ultra-high-definition endoscopic system including ultra-high-definition images, cordless design, small size, low cost, portability and high-speed wireless signal transmission.
