Technical Field
The invention belongs to the technical field of clinical medicine common surgery, and particularly relates to a puncture outfit for inflation-free transoral endoscopic thyroid surgery.
Background
In the traditional endoscopic thyroid surgery process, surgical smoke is often generated by using ultrasonic surgical knife, electrocoagulation hook and other instruments, and consists of 95% of water or vapor and 5% of cell fragments existing in particle form, so that the visual field in the surgery can be affected, potential harm to the health of operating room personnel can be caused, and in the prior art, a CO2 inflation method is mostly adopted, so that the surgical space is maintained, and the smoke in the surgical space can be discharged. However, CO2 aeration is at risk of causing diseases such as subcutaneous emphysema, mediastinal emphysema, hypercarbonemia, and carbon dioxide embolism. Moreover, a recent study on cervical cancer reports that the prognosis of laparoscopic cervical cancer surgery is poor relative to abdominal open surgery, and the analysis of the cause may be related to the spread of tumors caused by CO2 aeration. Therefore, the operation is a better choice by adopting the inflation-free method, but the operation difficulty is high, and the operation is reported at home and abroad. In the endoscopic thyroid surgery, a suspension method is used for maintaining a surgery operation space, and the subcutaneous surgery space is established by suspending the anterior cervical flap in the surgery process, so that the space maintenance effect same as CO2 inflation can be achieved, and related complications caused by CO2 inflation in the surgery can be effectively avoided. Also, the method of non-inflatable suspension also requires solving the problem of smoke generated by the surgical procedure, requiring continuous evacuation to remove the smoke to maintain a clear surgical field of view. However, the traditional endoscopic surgical puncture outfit has the defects that the traditional puncture outfit has smaller diameter, and the gas flow is limited when the insertion instrument is operated, so that the smoke is not smoothly discharged; in order to prevent CO2 gas leakage, the traditional puncture outfit is provided with an air leakage prevention device on the puncture outfit base, so that the operation base is obviously thickened, and the operation is performed through the stomatoscope thyroid gland.
