FIG. 1A is a front view of a thyroid surgery site model according to an embodiment of the present invention, and FIG. 1B is a front view enlarged view of a thyroid surgery site model according to an embodiment of the present invention.

1A and 1B, the thyroid surgery site model 100 includes a laryngeal area receiving housing 101, a depression 110, a larynx model 210, a larynx muscle model 220, (230).

The larynx model part 210 can be extended in the front-back direction. Illustratively, the larynx model part 210 may be formed in a shape corresponding to either of the thyroid cartilage and the annular cartilage. As another example, a model can be formed that simulates the shape in which the thyroid cartilage and the cartilage are connected. As will be described later, the thyroid surgery site model of the present invention is a model in which the human body lying on the operating table is simulated with the throat tilted for thyroid surgery. Therefore, the setting for the direction is set based on a lying state of the human body. The forward / backward direction may refer to the 12 o'clock direction forward and the 6 o'clock direction backward with reference to Fig. 1A. In addition, the 9 o'clock direction may mean the left direction and the 3 o'clock direction may mean the right direction. Referring to the upper side and the lower side with reference to Fig. 3, the upper side means 12 o'clock direction and the lower side means 6 o'clock direction.

The larynx muscle model part 220 may cover at least a part of the periphery of the larynx model part 210. Referring to FIG. 1B, the laryngeal muscle modeling unit 220 is disposed on both sides of the larynx modeling unit 210 with respect to the larynx modeling unit 220 And a sternocleidomastoid model unit 223, which are connected to the sternocleidomastoid model unit 221, the sternocleidomastoid model unit 222, and the sternal sinusoidal model unit 223. The elements of the laryngeal muscle model part 220 are merely examples, and may include various muscle model units, not limited to the model unit described above. In addition, the larynx muscle model part 220 may be formed of a material having elasticity. For example, it may be formed of any one of silicon and rubber. The material may also be formed of elasticity corresponding to the muscles. Illustratively, the laryngeal muscle modeling portion 220 may be provided with elasticity corresponding to the muscles of the laryngeal region. As another example, the elasticity of the thyroid supramolecular / sternocleidomatic model unit 221 and the elasticity of the sternocleidomastoid unit 223 may have different elasticity based on the muscles corresponding to each unit. The larynx muscle model 220 can provide the user practicing the thyroidectomy with the elasticity corresponding to the actual muscle and the inherent resistance of the muscle.

Surgical practice without thyroidectomy may mean cutting exercises of other human organs. For example, it may include cutting exercises of blood vessels connected to the thyroid gland, cutting exercises of the parathyroid glands, and the like. The first material may not be melted due to the high temperature generated when the ultrasonic cutting tool is operated when the surgical training practiced with the cutting of the meridian is performed. Illustratively, the first material may be a silicon material. The operating temperature of the ultrasonic cutting tool is about 150 degrees, and the silicon material has a melting point of 200 degrees. Therefore, when performing a surgical exercise in which the thyroid gland cutting exercise is not performed, the thyroid model part 230 provided with the first material can be maintained in its shape without being melted by the ultrasonic cutting tool.

As another example, the thyroid modeling unit 230 may be provided with a second material having a melting point lower than a temperature generated when driving the ultrasonic cutting apparatus, in case of a surgical exercise including thyroid cutting exercises. The second material may be, for example, a collagen material. The collagen material has a melting point of 80 degrees. Accordingly, when performing a surgical exercise including a thyroid cutting exercise, the thyroid model portion 230 provided with the second material can be melted by the ultrasonic cutting tool. Further, since the thyroid model part 230 is formed of a material having elasticity such as silicone or collagen, the elasticity corresponding to the actual thyroid is provided to the practitioner.

The contact area of the through-pin 20 with the larynx muscle model part 220 is greater than the contact area with the laryngeal muscle model part 220 with respect to the head part of the through- 21 may be interposed. As the washer 21 is interposed, the penetrating fins 20 can provide a frictional fixing force to a wider area of the muscular portion 220 of the occipital region.

8 is a view showing an outline of a human skin model according to an embodiment of the present invention. Referring to FIG. 8, the human skin model 300 may cover the upper side of the above-described thyroid surgery site model 100. The human skin model 300 may be a model for shaping the skin, that is, the skin, in a state in which the throat is tilted backward in response to the actual human body lying on the operating table and performing a thyroidectomy operation while the jaw is raised.

The human skin model 300 may include a neck portion skin model portion and a thorax skin model portion. In addition, the thoracic outer skin model portion may include an underarm model portion corresponding to an underarm of the human body. The human skin model 300 may be formed into a model including the thorax and the neck, taking into consideration that the surgical tool is inserted through the axilla and the isola during thyroid surgery. However, the present invention is not limited thereto.

Referring to FIG. 1A, the laryngeal area receiving housing 101 of the thyroid surgery site model 100 may be extended corresponding to the chest of the human body. Illustratively, the chest outer skin model portion of the human skin model 300 can be positioned on the upper surface of the larynx area housing 101 extending in correspondence to the chest, and the upper surface of the larynx area housing 101 Neck skin model part can be placed.

Referring to FIG. 8, holes may be formed in the outer portion of the outer chest model and the model portion of the axillary to enable entry of the thyroid surgical instrument. The thyroid surgical instrument may be inserted through the first hole 310 formed in the oil groove portion and the second hole 320 formed in the armpit portion. In addition, a spacing space capable of moving the thyroid surgical instrument may be formed between the human skin model 300 and the larynx area housing 101. In a real thyroidectomy, the thyroid surgery tool is inserted through a hole in the two shoulder and both armpits, and the thyroid gland tool removes the subcutaneous fat layer. After that, medical CO2 is injected to secure the operative space as the exfoliated space. Therefore, in the separated space, the medical carbon dioxide is injected into the peeled portion of the human body in the state where the subcutaneous fat layer of the human body is peeled, so that the surface of the neck can be formed in an expanded shape. As a space is formed between the human skin model 300 and the larynx-containing housing 101, a space for performing thyroid-cutting exercises can be provided.

It will be understood by those of ordinary skill in the art that the foregoing description of the embodiments is for illustrative purposes and that those skilled in the art can easily modify the invention without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single entity may be distributed and implemented, and components described as being distributed may also be implemented in a combined form.
