Detailed Description
The present invention will be described in further detail with reference to specific embodiments.
A thyroid puncture simulation teaching aid comprises a silica gel shell for simulating the shape of a human neck, contents for simulating thyroid tissue, a nodule mold, a cyst mold and a support.
The silica gel shell is in a semi-cylindrical shape, a cavity simulating the shape of a human thyroid is arranged in the silica gel shell, and a pore passage simulating a blood vessel and filled with red dye solution is arranged on the wall of the cavity; the cavity is provided with an opening with a sealing cover on the rear side plane of the silica gel shell, the periphery of the opening is fixedly connected with a hard sealing ring in a sealing way, and the sealing ring is detachably fixedly connected with the sealing cover in a sealing way.
The support comprises a base and a supporting rod, and the supporting rod is fixed on the base; the rear side of the silica gel shell is provided with a bayonet clamped on the support rod. The base is provided with a label of 'pathological thyroid gland of human neck'.
The volume of the nodular mold is 1-3cm3The wax block or the soft capsule filled with the filler. The cyst mold has a volume of 1-3cm3With a filled latex bladder. The content is gelatin (also known as fish gelatin and Gelidin). When the mold is used, the molten content is mixed with the nodular mold and the cyst mold and filled in the cavity, the content is condensed after cooling, and the nodular mold and the cyst mold are distributed on the content. Before the contents are not coagulated, the positions of the nodule mould and the cyst mould can be flexibly arranged according to the training and examination requirements.
