The invention provides a wireless laparoscope system and a using method thereof. An operating lamp and a camera are in wireless micro design, are adsorbed on a magnetic control device, are fed into an abdominal cavity through an abdominal wall sheathing canal by a wireless visual magnetic control taking and feeding device, and are adsorbed on a peritoneal surface of an anterior abdominal wall in a magnetic control mode at a proper angle; and images in the abdominal cavity are transmitted to in-vitro video terminals such as a mobile phone, a computer and an intelligent display screen in a wireless signal mode, and examination and operation in the abdominal cavity are performed, namely the wireless laparoscope is obtained. The invention further provides a handheld wireless laparoscope and a magnetic control pneumoperitoneum-free laparoscope space system. The defects of a laparoscope holding hand, a two-dimensional visual field and the like during the existing laparoscopic surgery are overcome, the shadowless and three-dimensional visual field is returned under the laparoscopic surgery, the obstruction of a hard laparoscope and a cable thereof is eliminated, the chopstick effect of mutual collision and shielding among surgical instruments is reduced, the equipment is simplified, the surgical manpower is released, the possibility of the individual laparoscopic surgery is improved, the efficiency of application, training and popularization is high, and the development of the laparoscopic surgery towards the aesthetic recovery of ultramicro wounds is effectively promoted.
