Electrode guide wire and nerve stimulation device

Abstract

The present invention discloses an electrode guide wire and a nerve stimulation device. The electrode guide wire can be applied in the nerve stimulation device and is configured to connect a stimulation generator and an auditory nerve, and also configured to extend into a cochlea and stimulate the auditory nerve located on the surface of the cochlea, and the electrode guide wire is provided with astimulation end configured to extend into the cochlea and a connection end configured to connect the stimulation generator in an axial direction; the length of the stimulation end in the axial direction is less than or equal to 30 mm, a first electrode plate is arranged on the stimulation end, and the first electrode plate is used for transmitting target electric signals to the auditory nerve; and the connecting end is provided with a second electrode plate. When the stimulation end all stretches into the cochlea, the first electrode plate is guaranteed to enter the cochlea to conduct effective electrostimulation of the auditory nerve, and in addition, the injury to the cochlea due to too deep position of the stimulation end and first electrode plate piece stretching into the cochlea is avoided.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to an electrode lead and a nerve stimulation device. Background technique [0002] For certain types of nervous system diseases, especially tinnitus, deafness and other diseases, electrical stimulation therapy is required to perform chronic electrical pulse stimulation on the corresponding targets of different diseases, with few side effects, which is an ideal treatment method. [0003] However, since the electrode pads for transmitting the target signal need to be implanted in the cochlea, the accuracy of the position of the electrode pads is required to be high. It is often easy to cause the electrode pad to be located too deep in the cochlea, resulting in damage to the cochlea; it is also prone to the problem that the electrode pad does not enter the cochlea, resulting in the inability to perform effective electrical stimulation.

Problems solved by technology

[0003] However, due to the need to implant the electrode sheet for transmitting the target signal into the cochlea, the accuracy of the position of the electrode sheet is relatively high

It is often prone to the problem that the electrode sheet is located too deep in the cochlea, resulting in damage to the cochlea; it is also prone to the problem that the electrode sheet does not enter the cochlea, resulting in the inability to perform effective electrical stimulation
