Description

A 3D printed cranial anatomical model

technical field

The utility model relates to the technical field of medical 3D printing anatomical models, in particular to a 3D printing cranial anatomical model.

Background technique

Traditional anatomy teaching models mainly rely on human specimens, but the sources of human specimens are limited, storage costs are high, and there is a risk of infectious disease infection when handling corpse specimens; human specimens have an unpleasant smell due to long-term immersion in formalin solution, which is difficult for teaching. The limited space is not conducive to medical teaching. In addition, due to the long time or improper preservation of the fine structure of human specimens, it is difficult to guarantee the anatomical structure, etc., and neurosurgeons have more stringent requirements for the study of cranial anatomy, and need to observe the structure of the human cranial brain. Casting the teaching model is time-consuming and laborious, and the details, especially the tiny blood vessels and nerves in the brain, are not fully processed, and the display effect is not good. Again, the teaching of anatomy with human specimens is unethical. Therefore, there is a great need for a new anatomical model of brain structure for medical study. In addition, during surgical training, it is necessary to cut the scalp and remove the flap before performing the bone grinding operation. In the prior art, there have been cranial anatomical models formed by 3D printing technology, but they are printed as a whole and only the lower cranium and blood vessels are printed. In this way, it is difficult to observe the intracranial vascular network, intracranial fine details, etc. The details of the internal tissue structure of the cranium, including blood vessels and nerves, are inconvenient for teaching demonstration and analysis, and there is no model with a scalp in the cranial anatomy model in the prior art, which is inconvenient to simulate the actual operation with a scalp Case.

Utility model content

For solving the problems of the technologies described above, the technical scheme of the utility model is as follows:

A 3D printed cranial anatomical model, including a skull, a scalp and an internal tissue structure of the cranium placed inside the skull, the skull includes an upper skull and a lower skull, and the scalp covers the surface of the upper skull, The scalp can be detached from the upper skull, and the inner tissue structure of the brain includes an intracranial vascular network, and the intracranial vascular network is detachably connected to the lower skull.

In teaching or preoperative analysis, the intracranial vascular network can be removed from the lower skull to observe and analyze the details of the intracranial vascular network. During surgical training, the scalp can be cut open, and the bone grinding operation can be performed after the flap is opened, so that the simulation operation can be closer to the real brain structure, making the analysis more accurate, and the scalp can be disassembled so that the scalp structure can be replaced , so that it is convenient to replace the scalp and repair the model when the scalp is damaged, saving costs.

Further, the upper skull and the lower skull are an integral structure, integrally formed by 3D printing, and the upper skull is provided with a bone window. It is convenient to observe and analyze the positional relationship between the internal tissue structure of the brain, including the intracranial vascular network, and the skull.

Further, the upper skull and the lower skull are two independent parts, which are respectively formed by 3D printing and then assembled to form a complete skull structure. It is convenient to observe and analyze the positional relationship between the internal tissue structure of the brain, including the intracranial vascular network, and the skull.

Further, the bone window is a hole formed by removing half of the structure of the upper skull.

Further, the upper skull is a detachable left and right parts, and the two parts are assembled with the lower skull to form a complete skull structure. Depending on the position of the internal structure of the cranium, a part of the upper skull or the entire upper skull can be selectively disassembled.

Further, the detachable left and right parts are engaged with each other, and the upper skull and the lower skull are engaged with each other. The way of card connection is convenient for disassembly. The detachable connection can also be achieved by magnetic materials being attracted to each other to split or combine the detachable left and right parts as well as the upper skull and the lower skull.

Further, the intracranial vascular network is detachably inserted into the lower skull. This can make disassembly easier and faster.

Further, the ratio of the 3D printed cranial anatomical model to the actual size of the human brain structure is 1:1.

Further, the 3D printed brain anatomical model is not equal to the actual size of the human brain structure.

Compared with the existing technology, the beneficial effect is: in the teaching or pre-operation analysis, the intracranial vascular network of the 3D printed cranial anatomical model can be removed; The internal details of the brain anatomical model can be observed and analyzed; another beneficial effect is that during surgical training, the scalp can be cut open, the skin flap can be opened, and bone grinding and other operations can be performed, so that the brain structure is more complete and the operation analysis is closer to reality. operate.
