the large-sized trachea retractor 30 is of an arc-shaped structure, the opening of the large-sized trachea retractor is obliquely arranged towards the lower right, and the upper right end of the large-sized trachea retractor is connected with the left end of the retractor connecting plate 50 to form a whole; the small-size air pipe drag hook 40 is of an arc-shaped structure, the opening of the small-size air pipe drag hook is obliquely arranged towards the lower left, and the upper left end of the small-size air pipe drag hook is connected with the right end of the drag hook connecting plate 50 to form a whole.

From the above, it can be understood that the present application is mainly used as a unilateral anti-drop atraumatic tracheal retractor 1000 in specific implementation.

In the specific application, more thyroid tumor operations are performed on adult male and female patients, and the external diameter of the neck trachea of the male patient is slightly larger than that of the neck trachea of the female patient aiming at the adult male and female patients, so the large-size trachea drag hook 30 for dragging the trachea with the relatively larger diameter of the male patient and the small-size trachea drag hook 40 for dragging the trachea with the relatively smaller diameter of the female patient are designed.

Therefore, when the neck trachea of the male patient with a relatively large diameter needs to be pulled in the operation, the large-size trachea draw hook 30 can be used for hooking the neck trachea of the male patient, the small-size trachea draw hook 40 can be pulled by the hand of an operating doctor or hooked on a fixing frame arranged on the operating bed or beside the operating bed, and the neck trachea of the male patient with the relatively large diameter can be stably pulled out, so that the operation space of the operating doctor is expanded, and the operation is facilitated.

Similarly, when the neck trachea of the female patient with a relatively small diameter needs to be pulled in the operation, the small-size trachea retractor 40 can hook the neck trachea of the female patient, the large-size trachea retractor 30 can be pulled by the hands of the operating doctor or hooked on a fixing frame erected on or beside the operating bed, and the neck trachea of the female patient with the relatively small diameter can be stably pulled open, so that the operation space of the operating doctor is enlarged, and the operation is facilitated.

In the above operation process, it is obvious that the large-sized trachea retractor 30 can be designed to be adapted stably to hook the male patient's neck trachea with a relatively large diameter, and the small-sized trachea retractor 40 can be designed to be adapted stably to hook the female patient's neck trachea with a relatively small diameter, so that the large-sized trachea retractor and the small-sized trachea retractor can be used integrally and conveniently, and the use is flexible and convenient.
