Embodiment 1

[0051] A specific embodiment of the present invention, such as figure 1 FIG discloses a semi-embedded housing 8 includes an upper housing and a lower housing 4, the lower housing 4 is provided on the upper cover 8 and sealed connector housing to form a sealed or semi-sealed receiving cavity, the housing 4 is a stepped structure. Further, the upper housing 8 and / or the lower housing 4 is provided with receiving portion, the receiving portion and / or the accommodating chamber can hold the medical device body, such as nerve stimulators, cochlear chips.

[0052] Please refer to Figure 10 , Figure 11 with Figure 14 In one preferred embodiment of the present invention, the upper housing having a first receiving space 8, the lower housing 4 having a second receiving space of the upper housing and the lower housing 8 4 are connected to form the sealing body receiving chamber (not shown in the figure). More specifically, as figure 2 , The lower housing 4 includes a stepped portion 41 fi...

Embodiment 2

[0058] Example 2 of the present embodiment is the embodiment of the housing half embedded in Example 1 is applied on one of the products neurostimulator preferred embodiment. When used as the semi-embedded housing body neurostimulator, which is performed on the basis of the embodiment 1 of the half-shell embedded fine-tuning, the nerve stimulator will be described in detail as an example.

[0059] like Figure 9 , Figure 10 with Figure 11 , The side of the stopper portion 42 is provided with a first flat portion 421; 8 side of the upper housing portion 23 is provided with a second plane. I.e. the top surface, and a second flat side surface portion 8 of the housing 23 together define a first receiving space; shape to the shape of the stopper portion 8 of the housing 42 is adapted to the . When the upper housing 84 is connected to the lower seal housing, said first planar portion and said second planar portion 23 are aligned to form a seal receiving cavity 421.

[0060] like Figure 1...

Embodiment 3

[0076] The present embodiment is based on the optimization of the design of Example 2, the optimization of the fixed portion of the electrode assembly mainly be described below for the optimization.

[0077] After the electrode 13 is inserted into the brain through the electrode fixing assembly needs to be secured to the skull, in order to avoid the offset target electrode and effective treatment. Thus the neural stimulator further comprises a stationary electrode assembly. like Figure 16 with Figure 17 Shown, the electrode assembly comprises an expansion fixing is inserted into the housing 241 and fixed expansion plug 242 in the housing 241. Wherein, the housing 241 is preferably conical expansion (expansion of the housing 241 may also be cylindrical). One end of the housing 241 of the expansion cone 2411 to open, the other end ( Figure 16 For the expansion of the bottom of the housing 241) to open threaded bore 2412, a threaded bore communicating with 24,122,411 coaxial tapered ...

Abstract

The invention relates to a semi-embedded shell and a stimulator, belongs to the technical field of full-head active implantation type medical instruments, and solves the problems that the implantation mode of a stimulator in the prior art is large in wounds and the infection risk is increased. The semi-embedded shell comprises an upper shell body and a lower shell body, wherein the upper shell body and the lower shell body are fixedly connected to form a sealed or semi-sealed containing cavity, and the lower shell body is in a step shape. According to the semi-embedded shell, the stimulator can be embedded into a counter bore of a skull in a semi-embedded mode, operation wounds are reduced, and operation risks are reduced.

Description

Technical field [0001] The present invention relates to active implantable medical devices Field whole head, in particular, relates to a semi-built-in housing and the stimulator. Background technique [0002] Implantable active medical device has been widely used for treating a variety of disorders, wherein an implantable active medical device for the electrical nerve stimulator, a pulse signal to pass through the electrodes neural tissue, to improve skills normal functioning of the human body. For example, it is more common DBS (Deep Brain Stimulation, implantable deep brain neurological stimulation electrode), can effectively improve the physical control and coordination of the patient suffering from a disease of the nervous system. This deep brain electrical nerve stimulation because of its minimally invasive, safe and effective, has become the preferred treatment options other than drugs. Therefore, research on implantable brain stimulator more and more attention has been pai...
