腹腔镜技术是外科学发展史上里程碑式的变革。传统腹腔镜的各类连接线存在限制腔镜移动、妨碍术中操作、潜在污染术区和引发安全事故等不足。为此我们团队历时五年首次研发了无线超高清腔镜系统，并介绍该系统的特点和模拟应用结果。

无线超高清腔镜系统将传统腔镜摄像电缆线和冷光源线进行了集成，并超低延迟无线传输到超高清监视器、手机端和云平台。选择30名医师使用该无线腔镜系统和传统国产有线高清腹腔镜手术系统进行拾豆试验、剪纸试验等腹腔镜基本操作，操作结束后在清晰度（赋值1-5分，5分非常清晰，1分非常不清晰）和握持感（赋值1-5分，5分非常舒适，1分非常不适）和图像延迟（有或无）三个方面对两个系统进行评价。

使用iso12233标准测试卡，无线腔镜的图像清晰度高于有线腔镜，其清晰度得分平均值大于有线腔镜[（4.8±0.4）vs（4.5±0.5），P=0.029]，握持感得分平均值大于有线腔镜[（4.6±0.7） vs（3.0±0.7），P<0.001]。在画面延迟感方面，无线和有线相比差异无统计学意义（P=0.99）。

本无线超高清腔镜系统拥有超高清显像、无线连接、小体积、低成本、易便携和高速无线传输等优势。

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.
