Problems solved by technology

[0002] The production of visual tract specimens is the most difficult technical operation of human anatomy. At present, the existing visual tract specimens are only displayed by a single peeling method, which is difficult to show its whole picture, and it is difficult to establish its overall view and three-dimensional sense. At the same time, it has not yet been used. , filled casting and other technologies, to display the visual conduction pathway and its corresponding blood vessels in situ and three-dimensionally, so it cannot meet the needs of basic medical teaching, scientific research, clinical application and popular science promotion

Embodiment

[0021] Embodiment: The preparation process of the specimen for comprehensive display of human visual conduction pathway and blood supply includes the following steps:

[0022] ①Select an adult head and neck specimen without traumatic brain injury, no tumor, fixed in 10% formalin for 3 to 6 months, intubate through bilateral common carotid arteries, inject anticoagulant, heparin sodium can be selected as anticoagulant Or sodium citrate aqueous solution, the volume ratio of sodium heparin or sodium citrate to water is 1-10:20000, and the blood in the blood vessel is discharged through the internal jugular vein.

[0023] ②Inject the filler into the blood vessel, and the degree of perfusion of the filler is best when the filler appears in the retinal artery. Use self-setting dental tray powder as solute, self-setting dental tray water as solvent, or ethyl acetate as solvent, perchlorethylene as solute, prepare filling agent, and inject it into the blood vessel. The solvent to sol...

Abstract

The invention discloses a human visual conduction path, a blood supply integrated display sample and a manufacturing method thereof. A sample is used for integrally and stereoscopically displaying a visual organ, the visual conduction path and blood supply of the visual conduction path. The manufacturing method includes the steps of obtaining an adult neck sample, injecting anticoagulant water solution into a blood vessel by an internal carotid cannula, discharging blood in the blood vessel through veins, injecting a filler into the blood vessel, removing a skull base after the solidificationof the filler, removing meninges, boiling the sample in medicinal water, and then sequentially dissecting each structure and the blood vessel of the visual conduction path from front to back. The advantages of the invention are as follows: a medicinal water boiling method is adopted matching with the blood vessel injection technology and the retina transparent technology, so as to display the three-dimensional space and shape of the visual conduction path from the skull base to the upper part, thereby providing visualized morphological basis for clinical teaching and scientific research.

Description

Technical field [0001] The invention relates to the technical field of human anatomy, in particular to a human body visual conduction path and blood supply comprehensive display specimen, and also relates to a preparation method of the specimen. Background technique [0002] The production of visual tract specimens is the most difficult technical operation of human anatomy. At present, the existing visual tract specimens are only displayed by a single peeling method, which is difficult to show its whole picture, and it is difficult to establish its overall view and three-dimensional sense. At the same time, it has not yet been used. , Filling casting and other technologies can display the visual conduction pathway and its corresponding blood vessels in situ and three-dimensionally, so it cannot meet the needs of basic medical teaching, scientific research, clinical application and popular science promotion. Contents of the invention [0003] The object of the present inven...
