Endoscopic thyroid surgery is increasingly accepted by patients, particularly young thyroid cancer patients, because of hidden scars or no scars on the body surface. As with open surgery, good exposure is critical to the success of the surgery. Thyroid retractor is often used in thyroid surgery, so that the purpose of fully exposing the surgical field is achieved.
However, the existing thyroid retractor is processed into a V shape or a W shape by using a metal wire (or a metal sheet), and the thyroid retractor only has a slight traction function by penetrating the skin to reach the neck endoscope area, so that the thyroid exposure degree in the operation is poor; the front end is at a sharp angle, so that the risk of puncturing blood vessels, nerves and air pipes in the operation is caused, and the safety is poor; in addition, an ultrasonic knife is continuously used in the operation, ultrasonic atomization of tissues occurs, the visual field is fuzzy, and the operation effect is affected; and waste liquid can also be generated to affect the operation field.

Detailed Description
The invention is further described below with reference to the drawings and examples.
In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present invention and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
As shown in fig. 1 to 3, this embodiment discloses a thyroid retractor, including pull rod 1 and coupler body 2, pull rod 1 and coupler body 2 are detachable connection, and coupler body 2 is inside to be equipped with the cavity, and pull rod 1 is hollow pole, and the inside passageway intercommunication coupler body 2 of pull rod 1 is inside the cavity, and the opening setting of cavity is in coupler body 2 one side of keeping away from pull rod 1, and it has reticulated shell structure 3 to fill in the cavity. The internal channel of the pull rod 1 and the cavity of the hook body 2 form an adsorption channel, and the pull rod 1 is used for being externally connected with negative pressure suction equipment, so that the smoke generated during the operation of electrocoagulation can be rapidly sucked out.
In order to be connected with negative pressure suction equipment, specifically, one end of the pull rod 1, which is far away from the hook body 2, is provided with a connecting cylinder, the connecting cylinder is connected with a suction valve, and the suction valve is used for being connected with a suction pipe of the negative pressure suction equipment. The outer wall of the suction valve, which is far away from one end of the connecting cylinder, is provided with anti-slip patterns so as to prevent the suction pipe from falling off. Through the hook body 2 with the cavity and the needle track expansion pull rod 1 matched with the hook body, waste gas and waste liquid in an operation area can be adsorbed in real time, the purpose of fully exposing thyroid lesions is achieved, the probability of secondary injury can be reduced, the operation time is shortened, and the operation effect of an operation is ensured.
The hook body 2 comprises a main body part 4, a hook part 7 and a boss 5, wherein the main body part 4 is of a thin-wall structure, a cavity is formed in the main body part 4, the hook part 7 and the boss 5 are respectively arranged at two ends of the same side of the main body part 4, the hook part 7 can be of a solid structure or a hollow structure which is not communicated with the cavity, and a threaded hole 6 which is communicated with the cavity is formed in the boss 5. The latticed shell structure 3 is commonly used in the construction field to form a good support for the thin wall of the main body part 4. The size of the hook body 2 needs to be matched with the size of a common clinical stamping card, so that under the condition that the size of the hook body 2 is limited, the net shell structure 3 maximizes the size of a cavity and ensures ventilation. In addition, the reticulated shell structure 3 can also differentiate tissue fragments and blood clots, so that the tissue fragments or blood clots can be effectively prevented from blocking the adsorption channel inside the drag hook. The reticulated shell structure 3 can also protect parathyroid glands, avoid overlarge attractive force and suck the parathyroid glands out of the body by mistake. The mesh of the latticed shell structure 3 includes, but is not limited to, a tetrahedral mesh, or a single-direction diagonal orthogonal forward-lying mesh, or a cross diagonal orthogonal forward-lying mesh.
One end of the pull rod 1 is provided with external threads, and the pull rod 1 is matched with the threaded hole 6 through the external threads to be connected with the hook body 2.
