In recent years, in the field of surgical operation, the minimally invasive technology of the laparoscope is advanced suddenly, and a plurality of operations which can be completed only by incision in the past can be completed by adopting the laparoscope mode at present. Initially, laparoscopic surgery is mainly applied to gastrointestinal surgery/hepatobiliary pancreatic surgery/gynecological surgery and the like in abdominal cavity, and as more and more patients have continuously improved requirements for surgical beauty, endoscopic surgery on parts of superficial organs/tissues is also gradually developed, such as endoscopic thyroid surgery, endoscopic breast surgery, endoscopic subcutaneous giant lipoma resection and the like. The body surface organ/tissue is subjected to endoscopic surgery, scars of patients are reduced, attractiveness is brought, and a choice is provided for many patients who love beauty.

The laparoscopic surgery in the abdominal cavity needs to inject carbon dioxide gas into the abdominal cavity to expand the existing abdominal cavity space, and then the surgical operation can be carried out. However, the endoscopic surgery of superficial organs/tissues does not have the existing space as the abdominal cavity, but the manual establishment of the surgical operation space during the operation, such as the endoscopic thyroid surgery, needs the manual establishment of the subcutaneous operation space between the axillary/nipple operation point and the neck thyroid. Tissue damage is large in the process of artificially establishing an operation space, and blood vessels are prone to rupture and bleeding. After the preliminary operation space is available, a more distant operation space can be further established through operation under the direct vision of the endoscope. However, this method of creating a preliminary operation space is inefficient, has a large tissue damage, is liable to rupture and bleed blood vessels, and increases the risk of operation.
