Problems solved by technology

[0004] However, with fully implantable cochlear implants, once the battery fails or becomes depleted, the battery needs to be surgically replaced
This not only causes physical and mental pain to patients, but also increases the financial burden on patients and their families.

Embodiment 1

[0027] figure 1 It is a schematic diagram of the power generation body of the self-powered electronic cochlea in Example 1 being quadrangular, such as figure 1 As shown, the self-powered electronic cochlea 20 has a power generation unit 200, an extracorporeal portion 17, and an intracorporeal portion 18. Wherein, the power generation part 200 includes a power generation main body 21, an output electrode 14. The power generation main body 21 is a rectangle, and each of the two narrow sides of the rectangle has a fixing unit 22 for moving the main body along the direction of the heart contraction along the long axis. Fixed on the epicardium. The fixing unit 22 is formed by extending the encapsulation layer outward, and there is no power generating structure such as electrodes or piezoelectric materials inside the fixing unit 22, so the power generating structure of the power generating main body 21 will not be damaged when fixed with sutures.

[0028] Except for the fixing unit 22,...

Embodiment 2

[0035] image 3 It is a schematic diagram of a self-powered electronic cochlea with a triangular power generation subject in an embodiment of the present invention, such as image 3 As shown, the power generation body 12 of the self-powered electronic cochlea 11 of the present invention is a triangle, and each vertex of the triangle has a fixed unit 13, an output electrode 14 and an electrode layer (see figure 2 ) Phase connection, the rectifier filter circuit 15 is connected with the output electrode 14, and the electric energy storage unit 16 is connected to the rectifier filter circuit 15 for storing the electric energy generated by the power generation part.

[0036] Such as image 3 As shown, the shape of the power generating body 12 is a triangle. When it is installed on the epicardium, the power generating body 12 is fixed on the epicardium of the myocardial wall by the fixing units 13 located at the three vertices of the triangle. The sides of the triangle of the power gen...

Embodiment 3

[0040] The difference between this embodiment and the first and second embodiments is that the external sound processor and microphone are integrated into the shape of a capsule and placed in the external auditory canal instead of hanging outside the auricle. The power supply wire of the electric energy storage unit of the power generation main body extends from the ear to supply power to the sound processor. This can further reduce the volume of the external part and improve comfort.

[0041]

[0042] Compared with the first embodiment, this modification has the same configuration except that the shape of the power generating body is an oblong. Such as Figure 4 As shown, the shape of the power generating body 42 is an oblong, and there are fixing units 41 at the two vertices of the oblong. The advantage of the shape of the power generating body 42 is that there are no sharp corners, which helps to reduce Damage to the heart.

[0043] Of course, the shape of the power generating...

Abstract

The invention provides a bio-energy electronic cochlea. The bio-energy electronic cochlea comprises an in-vivo portion and an in-vitro portion. The in-vitro portion comprises an external microphone, a sound processor and a transmission coil pulse generator. The in-vivo portion comprises a stimulus receiver, a multi-channel electrode array and a power generation unit. The power generation unit comprises a power generation body, an output unit, an electrical energy storage unit, a fixing unit and an encapsulation layer. The power generation body is of a multilayer film structure and comprises a piezoelectric material layer arranged on the center of the power generation body and electrode layers arranged on both sides of the piezoelectric material layer. The output unit is connected to the electrode layers to output the current generated by the power generation body to the electrical energy storage unit. The fixing unit is arranged on the edge of the power generation body and used for fixing the power generation body to the epicardium. The encapsulation layer covers the surfaces of the power generation body, the output unit, the electrical energy storage unit and the fixing unit. The self-powered electronic cochlea needs no battery replacement and can achieve lifetime use.

Description

Technical field [0001] The invention relates to an electronic cochlea, belonging to the field of medical equipment. Background technique [0002] With the continuous deepening of human understanding of various diseases, more and more diseases can be diagnosed or treated with implanted electronic devices. [0003] Among them, the electronic cochlea is a medical electronic device that uses a speech processor to convert sound into a certain coded electrical signal, and then directly excites the auditory nerve through an electrode system implanted in the body to restore and reconstruct the auditory function of deaf patients. Electronic cochlear implant technology has developed rapidly in the past 30 years. Currently, more than 40,000 patients with severe sensorineural hearing loss have received electronic cochlear implants worldwide. The fully implantable electronic cochlea developed in recent years is completely unaffected by the appearance of the recipient, which is beneficial to t...
