Laparoscopic surgery utilizes laparoscopes to provide a surgical field of view and other related instruments to perform the surgical procedure. In the operation, a minimally invasive instrument is established to enter an operation channel of the abdominal cavity through the puncture outfit, wherein one puncture outfit is required to make a corresponding incision on a human body, then the puncture outfit is placed into the human body, according to different symptoms, at least three puncture outfits or more puncture outfits are required to be used for laparoscope and other related instruments in the operation, as the number is increased, the more wounds are, the risk coefficient of visceral organ damage caused by placing the puncture outfit into the abdominal cavity is increased, the damage of a plurality of wounds to a patient is larger, the recovery time is longer, and meanwhile, scars can be left.

In addition, since the laparoscope and the surgical instruments enter through different puncture outfit channels, a plurality of medical staff are required to cooperate, for example, a doctor of the right hand is required to support the mirror, and the doctor of the right hand is required to cooperate to ensure that the field of view of the instruments held by the doctor of the main hand is clear, in this case, the doctor of the main hand always operates the surgical instruments at the second view angle, so that the doctor of the right hand and the doctor of the main hand are required to have enough mercy, the requirements on the surgical experience, the anatomical basis and the spatial third dimension of the doctor are very high, long-term team cooperation and experience accumulation are required, and the problems of long relevant operation learning curve, low time efficiency, high bleeding rate of patients, low popularization rate of the base layer and the like occur. In addition, in order to obtain better visual angles, the hand rest doctor can only rotate and adjust the position and the angle of the mirror continuously, so that the doctor of the main knife always sees the position of the instrument in the hand, and the adjustment process enables the laparoscopic picture to shake continuously, so that visual fatigue and even dizziness of the doctor are easily caused, and the working intensity and the operation risk are increased.

At present, although a camera is added in a sheath core of a puncture outfit in the related art, the function of the puncture outfit is visible in puncture, and the purpose is to avoid organ damage in the puncture process, an independent endoscope operation channel is still needed when an operation is performed, and a doctor of a main knife needs to perform operation actions of surgical instruments at a second visual angle with the assistance of an arm rest, so that the puncture outfit which integrates functions of a traditional endoscope and the puncture outfit on one instrument and has fewer incision channels, a first visual angle, continuous visualization, autonomous control of the doctor of the main knife and flexible control of the angle of the field of view of the camera is provided.
