Problems solved by technology

However, when there is a problem with the fixing of the sleeve, the sleeve will slide below the neck, so that the electrode will bear the fatigue load, and fatigue fracture of the electrode may occur, causing discomfort and safety hazards to the patient

Abstract

The invention provides a fixing device of an implanted medical apparatus, a machining method thereof and an implanted medical instrument. The fixing device of the implanted medical apparatus comprisesa base member and an additional member. The base member is used for installing the fixing device to the body of the medical instrument. At least partial surface of the additional member is an unsmooth surface. The additional member is at least partially embedded into the base member. According to the fixing device of the invention, the implanted medical apparatus can be reliably fixed at a specific position in human body and is closely combined with human body tissue, thereby ensuring long-term stability and high reliability in fixation.

Description

Technical field[0001]The invention relates to the field of implantable medical devices, in particular to an implantable wire fixing device.Background technique[0002]Traditional implantable nerve stimulation electrodes usually include a pulse generator and an electrode lead, and sometimes it is necessary to introduce an extension lead between the pulse generator and the electrode lead. The extension wire can make up for the insufficient length of the electrode wire directly connected to the pulse generator, and can also solve the problem of the mismatch of the interface between the electrode end of the electrode wire and the top cover of the pulse generator. In addition, it is very important that the extension wire has better bending fatigue performance than the electrode wire, and can withstand the fatigue load caused by frequent movement of the human neck.[0003]The extension cord usually includes a socket end, and the socket end is used for inserting the electrode lead and butting ...
