Problems solved by technology

There are several disadvantages in screw fixation: first, the price of the screw is expensive, which increases the medical expenses of the patient; The operation of screw installation in the operation is complicated and difficult to operate; four, the fixing of each extension wire and the connection of the electrode wire needs to be provided with screws, and when there are multiple connection parts, more screws need to be provided, which increases the The complexity of the operation, and improper operation may cause the screws to fall off, making the fixation invalid

Abstract

The invention relates to an implanted type electrical nerve stimulation system. The system comprises a pulse generator, at least one electrode wire and a protection sleeve, wherein the at least one electrical wire comprises an extension lead and an electrode lead, the extension lead is implanted in a human body through a created first subcutaneous tunnel and has a first end part and a second end part which are opposite in the extension direction, the first end part of the extension lead is electrically connected with the pulse generator, and the second end part of the extension lead is electrically connected with the electrode lead, so that a connection part is formed; the protection sleeve comprises a body, the body has at least two cavities which are formed in the body at intervals and used for accommodating the connection part, and the cross section area of the protection sleeve is larger than that of the subcutaneous tunnel.

Description

technical field [0001] The invention belongs to the technical field of implantable medical instrument manufacturing, and in particular relates to an implantable electrical nerve stimulation system and a protective cover applied to the implantable electrical nerve stimulation system. Background technique [0002] An implantable electrical nerve stimulation system is an active implantable medical device. The implantable nerve electrical stimulation system excites, inhibits or regulates the conduction of the nervous system through electrical stimulation, so as to achieve the therapeutic effect of restoring or improving the function of the human body. Implantable nerve electrical stimulation therapy has been proven to have definite curative effect on more than 20 kinds of neurological dysfunction diseases. Compared with traditional drug methods and surgical damage methods, implantable neurostimulation therapy is safe and reversible, and is being used more and more clinically. ...
