However, since what is illustrated in FIG. 1 is only exemplary, the auxiliary device 100 for brain surgery may not include at least one of the above-described configurations or may additionally include a configuration not mentioned.

Of these, both sides exist in the endothelium 120. One of the two surfaces is a surface that contacts the patient's head, and the other surface of both surfaces is a surface facing the opposite direction from the aforementioned one surface. A receiving portion is formed on the other surface, which will be described later.

The endothelium 120 may be created by a molding technique using a 3D printer. Specifically, the 3D printer receives image data about the shape of the patient's head, for example, CT or MRI, and molds the endothelium 120 to fit the shape of the patient's head and thus allow close contact with the patient's head. It can be created using In this case, the material of the inner skin 120 may be silicon, but is not limited thereto.

That is, since the endothelium in contact with the patient's head according to an embodiment is formed based on image data on the shape of the patient's head, it may be in close contact with the patient's head. Therefore, the patient may not feel discomfort when wearing the auxiliary device for brain surgery according to an embodiment.

In addition, since the auxiliary device for brain surgery according to an embodiment is in close contact with the head of the patient, the probability of being pushed or moved by an external force is low. Therefore, if such an auxiliary device for brain surgery is used, it becomes possible to accurately insert the surgical auxiliary device into the patient's brain even without drilling a hole in the brain.

The coupling portion may be engaged with the receiving portion formed on the endothelium 120, and when the coupling portion and the receiving portion are engaged with each other, the outer skin 110 and the endothelium 120 may be coupled to each other. Conversely, when an external force is applied to the outer skin 110 and the inner skin 120 coupled in this way, the engagement portion and the receiving portion may be released, and in this case, the coupling between the outer skin 110 and the endothelium 120 may also be released.

As described above, according to an embodiment, the outer skin is detachable from the inner skin. If the endothelium is damaged or contaminated during the surgery, it is possible to replace only the endothelium and use the previously used outer skin. That is, the outer shell, which is part of the configuration of the auxiliary device for brain surgery according to an embodiment, can be recycled.

Meanwhile, the above-described outer shell 110 may be standardized and provided. Specifically, the outer shell 110 may be prepared by being standardized in several ways according to gender, age, or race. For example, the outer shell 110 employed when the patient is an Asian male in their 50s and the outer shell 110 employed when the patient is a Western female in their 30s may be provided, respectively.

Next, the insertion guide unit 130 will be described. The insertion guide unit 130 may be coupled to the outer shell 110 or may be coupled to the outer shell 110 and then detachable therefrom. When the insertion guide unit 130 is coupled to the outer skin 110, the surgical aid may be inserted through a hole formed in the insertion guide unit 130. That is, the insertion guide unit 130 may serve as an insertion guide of an auxiliary device for surgery.

In this case, the hole provided inside the insertion guide unit 130 may be formed to have a depth corresponding to the length to which the surgical aid is to be inserted. Therefore, when the operator uses the insertion guide unit 130, it is possible to accurately invade (permeate) the surgical auxiliary device to a desired depth in the patient's brain.

Hereinafter, each configuration of the auxiliary device 100 for brain surgery will be described one by one.

First, the endothelium 120 will be described. FIG. 3 is a perspective view of the endothelium 120 shown in FIGS. 1 and 2, but since the one shown in FIG. 3 is only exemplary, the shape of the endothelium 120 is not limited to that shown in FIG. 3. .

Referring to Figure 3, the endothelium 120 has both sides. One of the two surfaces is a surface that contacts the patient's head, and the other surface of both surfaces is a surface facing the opposite direction from the aforementioned one surface. A receiving portion is formed on the other surface. For the accommodating part, reference will be made to FIG. 4 in which the box 126 disposed relatively above among the two dotted boxes 126 and 127 shown in FIG. 3 is enlarged.

Referring to FIG. 4 together with FIG. 3, the receiving portion may indicate a plurality of grooves formed on the other surface. Looking in more detail with respect to the grooves, as shown in FIG. 4, a plurality of grooves may be formed on the other surface to be parallel to each other in one direction, and a plurality of grooves may be formed to be parallel to each other while perpendicularly intersecting in one direction. For this reason, a grid pattern may be formed on the other surface as shown in FIG. 4.

Referring back to FIG. 3, a hole 127 may exist in the endothelium 120. The hole 127 is indicated by a dotted box 127 disposed relatively below among the two dotted boxes 126 and 127 shown in FIG. 3. The hole 127 may be a passage used when the surgical auxiliary device penetrates (invades) the head of the patient.

Meanwhile, in FIG. 3, although the endothelium 120 covers the entire skull of the patient, the hole 127 is shown, but the shape of the endothelium 120 is not limited to that illustrated in FIG. 3. For example, the endothelium 120 may not cover the entire skull of the patient and may have a shape including only a half including an operation site, and in this case, convenience of surgery may be increased.

Next, the outer shell 110 will be described. 5 is a perspective view of the outer shell 110 illustrated in FIGS. 1 and 2, but the shape of the outer shell 110 is not limited to that illustrated in FIG. 5, since the one illustrated in FIG. 5 is only exemplary. .

Specifically, the coupling portion of the outer skin 110 may be fitted to be engaged with the aforementioned receiving portion formed in the inner skin 120, and more specifically, the aforementioned groove (shown in FIGS. 3 and 4) forming the receiving portion. To this end, the coupling unit may include a plurality of rails parallel to each other in one direction as shown in FIG. 5, and may also include a plurality of rails perpendicular to each other and parallel to each other. . That is, the outer shell 110 may have a lattice shape as shown in FIG. 5.

Meanwhile, the insertion guide unit 130 may be coupled to the above-described rail of the shell 110, which will be described later.

Next, the insertion guide unit 130 will be described. 6 is a cross-sectional view of the insertion guide unit 130 shown in FIGS. 1 and 2, but the shape of the insertion guide unit 130 is limited to that shown in FIG. It does not become.

6, the insertion guide unit 130 may be coupled to at least two of the aforementioned plurality of rails constituting the outer shell 110, and more specifically, the outer shell 110, and may be combined and then separated. have. When the insertion guide unit 130 is coupled to the outer skin 110, the surgical aid may be inserted through a hole formed in the insertion guide unit 130. That is, the insertion guide unit 130 may serve as a guide for the insertion direction of the surgical auxiliary device.

At this time, the hole provided inside the insertion guide unit 130 may be formed to have a depth d according to the length to which the surgical aid is to be inserted. Therefore, when the operator uses the insertion guide unit 130, it is possible to accurately invade (permeate) the surgical auxiliary device to a desired depth in the patient's brain. That is, the insertion guide unit 130 may even serve as a guide for the insertion depth of the surgical auxiliary device.

As described above, according to an embodiment, since the endothelium in contact with the patient's head is formed based on image data on the shape of the patient's head, it may be in close contact with the patient's head. Therefore, the patient may not feel discomfort when wearing the auxiliary device for brain surgery according to an embodiment.

In addition, since the auxiliary device for brain surgery according to an embodiment is in close contact with the head of a corresponding patient, the probability of being pushed or moved by an external force is low. Therefore, if such an auxiliary device for brain surgery is used, it becomes possible to accurately insert the surgical auxiliary device into the patient's brain even without drilling a hole in the brain.

In addition, the outer skin is detachable from the inner skin. If the endothelium is damaged or contaminated during the surgery, it is possible to replace only the endothelium and use the previously used outer skin. That is, the outer shell, which is part of the configuration of the auxiliary device for brain surgery according to an embodiment, can be recycled.

In addition, it is possible to guide the insertion direction and insertion depth of the surgical auxiliary device due to the insertion guide part.

As mentioned above, each of the receiving portions 121, 122, and 123 is engaged with each of the coupling portions 111, 112, and 113. In this case, in the first embodiment, when each of the receiving portions 121, 122, 123 and each of the coupling portions 111, 112, 113 are engaged with each other, gaps 125, 126 (or spaced apart) may be formed therebetween. Figure 7 shows these gaps 125 and 126 (or spacing).

In order to form the gaps 125 and 126 (or separation) in this way, an under-cut must exist in the receiving portions 121, 122 and 123. In the case where the undercut is present, the coupling between the outer skin 110 and the inner skin 120 may be easier than if it is not.

On the other hand, Figure 8 shows a cross-section when the outer skin 110 and the endothelium 120 are combined in the auxiliary device for brain surgery 100 according to the second embodiment.

Referring to FIG. 8, a plurality of receiving portions 121, 122, and 123 are present in the inner skin 120, and a plurality of coupling portions 111, 112, and 113 are present in the outer shell 110 as well. As mentioned above, each of the receiving portions 121, 122, and 123 is engaged with each of the coupling portions 111, 112, and 113. At this time, as described above, the receiving portions 121, 122, and 123 are formed of grooves. In the second embodiment, the depths of the grooves of the receiving portions 121, 122, and 123 may be different from each other. As illustrated in FIG. 8, the depth of the receiving portions 121 and 123 is different from the depth of the receiving portion 122. In this case, the length in which the coupling portions 111 and 113 are accommodated by the receiving portions 121 and 123 may be shorter than the length in which the coupling portion 112 is accommodated by the receiving portion 122.

When the lengths of the coupling portions accommodated by the receiving portion are different from each other, the coupling between the outer skin and the inner skin may be made more easily even when the scale of the outer skin is larger than the scale of the inner skin.
