DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0024] Combination Figure 1-Figure 6 An implantable neural stimulation device for neurosurgery includes a controller body 1 fixedly installed in a skull groove, a connection groove 12 is opened on one side of the controller body 1, an electrode wire body 11 is connected to the inner wall of the connection groove 12, a plurality of fixing seats 13 for connecting with titanium nails are fixedly arranged on the outer edge of the controller body 1, and a medical silicone sleeve 2 is arranged on the outer edge of the controller body 1.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] The medical silicone sleeve 2 is prefabricated into the shape of the space between the outer edge of the controller body 1 and the inner wall of the skull groove. The upper surface of the medical silicone sleeve 2 is parallel to the upper surface of the controller body 1. A medical silicone isolation pad 4 is provided on the inner side of the medical silicone sleeve 2. The medical silicone isolation pad 4 adapts to the shape of the connecting groove 12 and covers the upper part of the connecting part between the electrode wire body 11 and the controller body 1. The outer surface of the medical silicone sleeve 2 is provided with an opening 5 for the electrode wire body 11 to pass through, and the upper surface of the medical silicone sleeve 2 is provided with a groove 3 for the fixing seat 13 to be embedded.

[0027] The above working principle and technical effect are: the gap between the controller body 1 and the inner wall of the skull groove is filled by the medical silicone sleeve 2, and the medical silicone isolation pad 4 is used to cover the connecting groove 12, 13 is embedded in the groove 3, and the upper surface of the fixing seat 13 is in the same plane as the upper surface of the medical silicone sleeve 2, so as to smooth the gap between the outer surface of the skull and the upper surface of the controller body 1, making it difficult for the patient to perceive the existence of the controller body 1, thereby reducing the sense of presence of foreign matter.

[0028] In the previous embodiment: the medical silicone sleeve 2 includes an inner connecting portion 21 adapted to be connected to the outer edge of the controller body 1, and an outer deforming portion 22 arranged on a side of the inner connecting portion 21 away from the controller body 1, and the appearance of the outer deforming portion 22 is deformed by pressure.

[0029] The above working principle and technical effect are: a fixed connection is established between the inner connecting part 21 and the outer edge of the controller body 1, and the easily deformable outer deformable part 22 is convenient for adapting to the shape of the inner wall of the skull groove, thereby facilitating full filling of the gap between the controller body 1 and the skull groove.

[0030] In the previous embodiment: a storage cavity 23 is provided between the inner connecting portion 21 and the outer deformation portion 22 . The storage cavity 23 is provided in an annular shape inside the medical silicone sleeve 2 . The storage cavity 23 is filled with liquid silicone.

[0031] The above working principle and technical effect are as follows: since the skull groove is manually opened by the doctor, and the controller body 1 is also manually installed in the skull groove by the doctor, the distance between the skull groove wall and the outer edge of the controller body 1 is different, which easily leads to different deformation amounts of different parts of the outer deformation part 22, which easily leads to poor flattening effect produced by the outer deformation part 22;

[0032] By opening a storage cavity 23 in the medical silicone sleeve 2 and filling the storage cavity 23 with liquid silicone, the liquid silicone can flow in the storage cavity 23. For the narrower position between the outer edge of the controller body 1 and the inner wall of the skull groove, the storage cavity 23 at that position is squeezed and has a smaller spatial position, so the amount of liquid silicone stored is smaller. For the wider position between the outer edge of the controller body 1 and the inner wall of the skull groove, the storage cavity 23 at that position has a larger spatial position, so the amount of liquid silicone stored is larger. In this way, the liquid silicone is adaptively and evenly distributed in the gap between the controller body 1 and the skull groove, and gap filling is implemented to achieve smooth filling.

[0033] In the previous embodiment: an injection tube 6 is arranged on the inner side of the medical silicone sleeve 2, the injection tube 6 is connected to the storage chamber 23, the opening of the injection tube 6 passes through the medical silicone isolation pad 4 and is exposed on the upper surface of the medical silicone isolation pad 4, and a one-way valve is arranged inside the injection tube 6 which is one-way connected to the inner side of the storage chamber 23.

[0034] The above working principle and technical effect are: due to the setting of the injection tube 6, it is convenient to first install the controller body 1 together with the medical silicone sleeve 2 into the skull groove, and then inject liquid silicone into the storage cavity 23 through the opening set on the upper surface of the medical silicone isolation pad 4 through the injection tube 6. In this way, it is convenient to control the amount of liquid silicone injected into the storage cavity 23, so that the total volume of the medical silicone sleeve 2 together with the liquid silicone adapts to the gap between the controller body 1 and the skull groove, thereby further realizing the smooth filling of the gap.

[0035] In the previous embodiment: a medical silicone covering pad 7 is also provided on the upper surface of the controller body 1, the edge of the medical silicone covering pad 7 is integrally connected to the upper edge of the medical silicone sleeve 2, and the upper surface of the medical silicone covering pad 7 is set as an arc surface adapted to the skull surface.

[0036] The above working principle and technical effect are: by setting the arc surface on the upper surface of the medical silicone covering pad 7, the arc surface of the complete skull is made, the overall sense of the skull is improved, and the foreign body sensation is further reduced when the patient touches the position where the controller body 1 is located outside the scalp.

[0037] In the previous embodiment: the outer edge of the medical silicone covering pad 7 is provided with a plurality of protrusions 71 , and the plurality of protrusions 71 correspond to the fixing seat 13 one by one and are provided on the upper side of the fixing seat 13 .

[0038] The above working principle and technical effect are: a groove for embedding the mounting base 13 is opened on the skull, and after the mounting base 13 is embedded in the groove and fixed by the titanium nail, the titanium nail is covered by embedding the protrusion 71 in the above groove for installing the fixing base 13, and the upper surface of the protrusion 71 is in the same plane as the outer surface of the skull.
