Embodiment Construction

[0018] figure 1 is a schematic diagram of a prior art implantable electrical nerve stimulation system. refer to figure 1 , the prior art implantable nerve electrical stimulation system mainly includes a pulse generator 1 implanted in the body, an extension lead 2 and an electrode 3, and a control device located outside the body. The pulse generator 1, the extension lead 2 and the electrode 3 are connected in sequence. Wherein, one end of the electrode 3 is connected to the extension wire 2 . An extension wire protection sheath 4 is provided at the junction of the extension wire 2 and the electrode 3 for protecting the connection between the extension wire 2 and the electrode 3 .

[0019] At present, due to the lack of a corresponding fixing device, the extension wire protective sheath 4 will move relative to the surrounding body tissue with the movement of the patient's body, thereby causing friction with it, causing discomfort to the patient, and even causing pain or other...

Abstract

The invention provides an extension wire protective sleeve of an implanted nerve electrical stimulation system. The extension wire protective sleeve comprises a protective sleeve main body and is characterized by comprising a fixing device, wherein the fixing device is arranged inside the protective sleeve main body and provided with an installation part extending out of the protective sleeve main body. According to the extension wire protective sleeve of the implanted nerve electrical stimulation system, the extension wire protective sleeve is appropriately fixed without causing discomfort of a patient due to movement of peripheral body tissues.

Description

technical field [0001] The invention relates to an implanted nerve electric stimulation system, in particular to an extension wire protective sleeve of the implanted nerve electric stimulation system. Background technique [0002] Electrical nerve stimulation plays an important role in the treatment of nerve dysfunction and rehabilitation of nerve injury. The implantable nerve electrical stimulation system releases high-frequency electrical stimulation by implanting electrodes at specific nerves in the human body, such as motor nerves and sensory nerves, to stimulate specific nerves, thereby restoring human body functions to normal operation. At present, implantable electrical nerve stimulation systems mainly include implantable deep brain stimulation (DBS), implantable cerebral cortical stimulation (CNS), implantable spinal cord stimulation system (SCS), implantable sacral nerve electrical stimulation System (SNS), Implantable Vagus Nerve Stimulation System (VNS), etc. ...
