Problems solved by technology
However, since the sealing sleeve and the connector belong to two separate parts, the assembly between the two needs to be considered, and the sealing sleeve is finally used to tie the two ends of the cord to achieve the purpose of sealing. This type of sealing method Low reliability and poor stability
In addition, when the extension wire corresponds to the conductive ring of the electrode wire at the joint and is connected, it is necessary to lock the conductive ring with screws and realize the electrical connection between the electrode wire and the extension wire, but this method will damage the conductive ring and affect the electrical connection effect

Embodiment Construction
[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0023] In order to treat diseases such as nerve dysfunction and nerve damage in the human body, the electrical nerve stimulation system shown in the present invention needs to implant a pulse generator, an extension lead connected to the pulse generator, and an electrode lead connected to the extension lead. In the human body, the electrodes in the lead are used to electrically stimulate the nerves. A channel is provided in the extension wire, and the electrode wire is inserted into the channel and docked with the extension wire. In order to increase the connection stability between the extension wire and the electrode wire, a fixed component is provided in the channel to ...

The invention relates to an electrical nerve stimulation system. The electrical nerve stimulation system comprises an extension wire and an electrode wire connected with the extension wire, wherein achannel is formed in the extension wire, the electrode wire is inserted into the channel and is in butt joint with the extension wire, and a fixed assembly used for limiting the electrode wire to movein the channel is arranged in the channel. According to the method, the step of additional sealing after the electrode wire and the extension wire are in butt joint is omitted, and the used fixed assembly is simple in structure, easy to manufacture, good in sealing performance, low in cost, time-saving, labor-saving and reliable.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a nerve electrical stimulation system. Background technique [0002] Electrical nerve stimulation is a commonly used method for the treatment of neurological disorders and the rehabilitation of nerve injuries. Typically, an electrical nerve stimulation system includes a pulse generator implanted in the body, extension leads and electrode leads, and a control device located outside the body. One end of the extension lead is connected to the pulse generator and the other end is connected to the electrode lead, so that the pulse generated by the pulse generator is transmitted to the electrode lead to electrically stimulate the nerve. Since the pulse generator, the extension lead and the electrode lead are implanted into the human body, it is necessary to ensure that the connection between the extension lead and the electrode lead is tight to avoid unnecessary operations dur...
