Problems solved by technology

However, the structure of the mold model specimen is simple, the process is complicated, the cost is high, and the size of the specimen is rigid and inflexible.
There is a certain deviation between the teaching and the real specimen, and the display of the name of the real structure of the specimen cannot be realized

Embodiment 1

[0028] A method for preparing specimens related to human cerebrovascular interventional surgery, comprising the following steps:

[0029] Step (1), material selection:

[0030] Human specimens that are intact, without trauma, fractures, and lesions are selected.

[0031] Step (2), anticorrosion treatment:

[0032] Formalin was used as the preservative solution to carry out antiseptic treatment on the human specimen.

[0033] Formalin preservative solution is prepared by mixing formaldehyde and distilled water, and the volume concentration of formalin is about 30%. The specimen can be soaked for 3 to 4 months.

[0034] Step (3), drawing materials:

[0035] Keep the head, chest and abdomen, cut the ribs at the posterior axillary line, remove part of the ribs, sternum, and diaphragm, open the chest and abdominal wall, and completely remove the upper limbs on both sides along the edge of the scapula and clavicle, and cut the lower limbs horizontally at the middle of the thigh....

Embodiment 2

[0058] The difference with Example 1 is only that the bleaching time in the step (5), the bleaching time is 3 days.

Embodiment 3

[0060] The difference with Example 1 is only that the concentration of the bleached hydrogen peroxide solution in step (5) adopts 8%.

Abstract

The invention relates to a specimen making method for a human cerebrovascular interventional operation, which comprises the following steps of selecting a human specimen and performing preservative treatment on the human specimen; selecting materials, wherein the head, the thorax and the abdomen are reserved, part of ribs and sternum are removed, upper limbs on the two sides are removed, and the middles of thighs are cut open; annularly sawing the top of the craniotomy, removing skin superficial fascia on the right side of the face, displaying parotid gland, removing skin superficial fascia onthe left side of the face, and exposing maxillary artery and branches; reserving partial skin and superficial fascia on the right side of the lower limb, removing the skin and superficial fascia on the left side, and displaying great saphenous veins, femoral arteries and branches; in the thoracic cavity: removing superficial fascia and deep fascia, and exposing heart appearance and head and arm stems; bleaching and washing the specimen; cleaning redundant tissues on the surface of the specimen; threading a guide wire, wherein in the right groin area, the guide wire is slowly inserted along the femoral artery till the common iliac artery, the internal carotid artery and the basilar artery are reached. And the prepared specimen has strong sense of reality, is beneficial to specimen observation, and is convenient for teaching and learning.

Description

technical field [0001] The invention relates to the technical field of human body specimen preparation, in particular to a preparation method for human cerebrovascular interventional specimens. Background technique [0002] Ischemic stroke is caused by cerebral blood vessels being blocked by thrombus. In addition to dissolving it with thrombolytic drugs, some special instruments can be gradually introduced from peripheral blood vessels to cerebral blood vessels to remove the thrombus blocking the cerebral blood vessels. The latter is called cerebrovascular interventional therapy. To put it simply, it is necessary to make a small hole in the femoral artery at the root of the patient's thigh, insert the guide wire balloon, etc., and slowly lead it to the cerebral blood vessel under the guidance of imaging, find the thrombus, and finally use mechanical stretching , Balloon dilation, etc. to remove the thrombus, re-canalize the blood vessel, and save the brain cells.
