In the traditional endoscopic thyroid surgery process, surgical smoke is often generated by using instruments such as an ultrasonic scalpel, an electrocoagulation hook and the like, the surgical smoke is composed of 95% of water or water vapor and 5% of cell fragments in particle form, the clear visual field in the surgery can be influenced, potential harm can be caused to the physical health of personnel in an operating room, and the smoke in the surgery space can be discharged while the surgery space is maintained by adopting a CO2 inflation method in the prior art. However, CO2 aeration is at risk of causing diseases such as subcutaneous emphysema, mediastinal emphysema, hypercapnia, and carbon dioxide embolism. In addition, a recent research report on cervical cancer is that the prognosis is poor compared with that of open abdominal surgery and endoscopic cervical cancer surgery, and the reason for analysis is probably related to tumor dissemination caused by CO2 inflation. Therefore, the non-inflatable method is a better choice for operation, but the operation difficulty is higher, so that the method is rarely reported at home and abroad. In the endoscopic thyroid surgery, the surgical operation space can be maintained by utilizing a suspension method, a subcutaneous operation space is established by suspending a skin flap in front of the neck in the surgical process, the space maintaining effect same as that of CO2 inflation can be achieved, and related complications caused by CO2 gas filling in the surgery can be effectively avoided. Similarly, the non-pneumatic suspension method also needs to solve the problem of smoke generated by the operation, and needs continuous air suction to remove the smoke so as to keep the operation visual field clear. However, the traditional puncture outfit for endoscopic surgery has the disadvantages that the diameter of the traditional puncture outfit is small, the gas circulation is limited when the traditional puncture outfit is inserted into an instrument for operation, and smoke is not discharged smoothly; secondly traditional puncture ware is in order to prevent that CO2 is gaseous to leak outward, all is provided with leak protection gas device at the puncture ware base to obviously thickened the operation base, through the oroendoscopic thyroid surgery, because operating space is little, traditional puncture ware base is easy to interfere with each other, is unfavorable for the operation. In order to solve the problems, the traditional inflatable endoscope puncture outfit is improved.
