Embodiment 1

[0053] This embodiment provides a bendable pulse generator, such as Figure 2-3 As shown, it includes: a main body part 1 installed with a first part of parts; a top cover part 2 installed with a second part of parts, and at least one of said second parts and at least one of said first parts can pass through The circuit is electrically connected; the soft covering layer 3 completely covers the main body part 1 and the top cover part 2 , and forms a flexible connection part 31 between the main body part 1 and the top cover part 2 .

[0054] In this embodiment, the soft coating layer 3 is a silicone rubber coating layer. Those skilled in the art may also use other materials with similar effects. As a variant, the soft covering layer 3 can also partially wrap the main body part 1 and the top cover part 2 , as long as the soft connection part 31 can be formed between the main body part 1 and the top cover part 2 .

[0055] The advantage of such an arrangement is that the main bo...

Embodiment 2

[0071] This embodiment provides a bendable pulse generator, which is an improvement on the basis of Embodiment 1, the difference is that, as Figure 8 As shown, a protrusion 14 is also included, which is formed by at least a part of the main body part 1 facing the human body protruding outward, and the protrusion 14 forms an installation space inside the main body part 1 .

[0072] The bendable pulse generator of this embodiment can reduce the plane area of ​​the entire main body part 1 and increase the depth, so as to accommodate the installation of the first part of the parts and reduce the removal area of ​​the skull. Part 14 deepens the opening of the skull groove and reduces the convexity of the scalp surface.

[0073] The implantation effect of the pulse generator in the present embodiment on the skull 7 is as follows: Figure 9-11 As shown: a bone groove 71 is opened on the skull 7, and a deeper bone groove is opened relative to the position of the protrusion 14 to acc...

Embodiment 3

[0075] This embodiment provides an implantable nerve electrical stimulation system, comprising: a pulse generator; a stimulating electrode, one end of which is connected to the electrode connector of the pulse generator, and the other end is suitable for contacting the nerve; a fixing device for stimulating The electrodes are fixed on the skull; the external control equipment (not shown in the figure) can communicate with the pulse generator wirelessly, and can read the equipment information of the pulse generator and adjust the stimulation parameters; the pulse generator is an embodiment 1 or the pulse generator in embodiment 2.

[0076] In the implantable electrical nerve stimulation system of this embodiment, the pulse generator used is the pulse generator in Embodiment 1 or Embodiment 2. Since the above-mentioned pulse generator is used, it naturally has with all the advantages.

Abstract

The invention provides a bendable pulse generator and an implantable nerve electrical stimulation system. The bendable pulse generator comprises a main body part and a top cover part, a first part component is installed on the main body part, a second part component is installed on the top cover part, and the second part component and the first part part component can be connected through a circuit; and a soft coating layer partially or completely coats the main body part and the top cover part, and a soft connecting part is formed between the main body part and the top cover part. The invention discloses the bendable pulse generator, the main body part and the top cover part can be relatively bent for a certain angle through the flexible connecting part; when the bendable pulse generatoris implanted into the head of a human body, only the main body part needs to be installed in the skull groove, and the top cover part is bent by a certain angle relative to the main body part and thenattached to the surface of the skull, so that the formed skull groove is small and shallow, the operation difficulty can be reduced, the postoperative effect is good, and the pain of a patient is small.

Description

technical field [0001] The invention relates to the technical field of implantable medical instruments, in particular to a bendable pulse generator and an implantable nerve electrical stimulation system that can be used for head implantation. Background technique [0002] For certain types of nervous system diseases, such as Parkinson's disease, epilepsy, torsion spasm, spastic torticollis, chorea, idiopathic vertigo, etc., clinically commonly used drug therapy and surgical treatment, but the side effects and complications are very serious. big downside. Deep brain stimulation therapy is to stimulate the different functional nuclei in the deep brain with chronic electrical pulses, such as stimulating the subthalamic nucleus and globus pallidum for Parkinson's disease, which plays a role in the treatment of causes and is a reversible neuromodulation. Treatment is a relatively ideal treatment method, and its current application is becoming more and more extensive. [0003] T...
