Embodiment 1

[0032] A method for making a plasticized specimen of the positional relationship between the spinal cord and the intervertebral disc, comprising the following steps:

[0033] (1) Material selection:

[0034] Human specimens that are intact, without trauma, fractures, and lesions are selected.

[0035] (2) Anti-corrosion treatment:

[0036] Preserve the selected human specimens, perfuse the specimens with formalin with a volume concentration of 18%, penetrate the formalin into various parts of the specimens through large blood vessels (femoral artery, common carotid artery), and finally put them in Soak in 10% formalin solution for 3 months.

[0037] (3) Materials:

[0038] Open the top of the skull with the head, remove the brain tissue, cut with a diagonal saw at the position 1 cm above the foramen magnum on both sides of the temporal bone, and remove the front half, keeping part of the occipital bone; remove both sides at the sacroiliac joint of the hip The hipbone and t...

Embodiment 2

[0057] A method for making a plasticized specimen of the positional relationship between the spinal cord and the intervertebral disc, comprising the following steps:

Abstract

The invention relates to a plasticized specimen for the positional relationship between a spinal cord and an intervertebral disc and a manufacturing method of the plasticized specimen. The manufacturing method of the plasticized specimen for the positional relationship between the spinal cord and the intervertebral disc comprises the following steps of carrying out antiseptic treatment on a selected human body specimen; preparing materials for manufacturing, completely reserving the intervertebral disc, cleaning the spinal cord and the spinal nerve at a vertebral body removal position, and clearly displaying the positional relationship between the spinal nerve and the intervertebral disc; bleaching the specimen; soaking the bleached specimen in an acetone solution for 50-70 days; placing the dehydrated and degreased specimen in silica gel in a vacuum pressure bin for standing for 40-50 days; taking out the impregnated specimen from silica gel, shaping and repairing; placing the specimen in a curing box and curing with a curing agent for 10-15 days. According to the preparation method of the specimen, a real organism is taken as the specimen, the shape and structure of the specimenare complete and unchanged, the reality is high, later specimen observation is facilitated, the use and operation are simple, teaching by teachers and learning by students are facilitated, the specimen is nontoxic and tasteless, and long-term storage is facilitated.

Description

technical field [0001] The invention relates to the technical field of biological plasticized specimens, in particular to a plasticized specimen of the positional relationship between a spinal cord and an intervertebral disc and a manufacturing method thereof. Background technique [0002] At present, biological specimens commonly used in teaching and learning in schools include: opening the spinal canal from the back to display spinal cord plastination specimens, model specimens, and soaked bottled specimens. [0003] Immersion bottled specimens, the preparation process of the impregnated specimens is simple, they need to be preserved in the preservation solution, and cannot be exposed to the air for a long time, and they are toxic and have a pungent smell, and the position and shape of the specimen cannot be intuitively felt by hand. There is a certain deviation from the real specimen, and the display of the name of the real structure of the specimen cannot be realized. ...
