Background technology
Implantable neural electrical stimulator is a kind of active implantable medical devices.Implantable neural electrical stimulator by the mode of electrostimulation come excited, suppress or regulate nervous system conduction, thus reach the result for the treatment of recovering or improve function of human body running.Implantable neural electrical stimulation therapy has been proved plants maladjusted nervous system disease to more than 20 and has definite curative effect.Compare with operation damage method with traditional pharmaceutical methods, implantable neural electrical stimulation therapy safety is reversible, is used just more and more clinically.Implantable neural electrical stimulator, according to the difference of stimulation location, can be subdivided into brain depth stimulator, vagus nerve stimulator, spinal stimulator, peripheral nerve stimulation device etc.
Similar with widely used cardiac pacemaker system, implantable neural electrical stimulator is also made up of the wire (being called electrode or extension lead) of the pulse generator and transmission stimulus signal that produce stimulus signal.Because of the difference of various system practical application, implantable neural electrical stimulator or be made up of pulse generator, extension lead, electrode three part, or only have pulse generator and electrode two parts composition.This two type systematic is all needed to set up convenient, safe and reliable plug-in between pulse generator with extension lead (or electrode) be connected, namely can either fast, effectively connect between the pulse generator of suitable model and extension lead (or electrode), without damage both can be separated again, so that change some assemblies wherein.
Plug-in is connected in cardiac pacemaker or defibrillator and widely uses, and defines international standard, such as IS-1, DF-1, IS-4 and DF-4 connector standards.IS-1 connector can only realize at most the electrical connection of two passages, and the connector size for connecting is approximately diameter 3.2mm, length 20mm.DF-4 connector can realize the electrical connection of four passages, and the connector size for connecting is approximately diameter 4.2mm, length 30mm.Stimulation system needs to realize more multichannel connection, if directly use the AN connector such as existing IS-1, the cumulative volume of connector will become very large, and aggravation patient implants the risk of rear generation skin infection or ulceration.
In view of the needs of clinical practice, be necessary to develop the less connector of a kind of volume, use and reduce the risk that patient develops complications to facilitate doctor.
Summary of the invention
The purpose of this utility model is to provide a kind of high density attachment plug for implantable neural electrical stimulator, and the socket that it can adapt under less volume and with it coordinates the connection realized between pulse generator and extension lead (or electrode).
The technical solution adopted in the utility model is:
Described plug is cylindric or aciculiform, is made up of retainer ring, connecting ring, insulator, protection tube and connecting line; Its one end is insertion end, and the other end is protection tube, is separated between insertion end and protection tube by retainer ring; Multiple connecting ring is distributed in the insertion end of plug; Between each connecting ring and between connecting ring and retainer ring, insulator is set respectively;
Connecting line is connected ring, insulator, retainer ring and protection tube parcel; Connecting line is monofilament wire, and its end directly welds with the inwall of connecting ring; Or connecting line is the twisted wire that many filament conductor are formed, and its link is crimped in capillary, is welded with the inwall of connecting ring by capillary.
The welding manner of described capillary and connecting ring is resistance spot welding or laser welding.
Described connecting line is made up of the insulating barrier of outside and the wire of centre.
The end of described plug is taper.
The beneficial effects of the utility model are:
The socket that can adapt under less volume and with it coordinates the connection realized between pulse generator and extension lead (or electrode), and manufacture process is stable, reliability is high, and overall volume is little, Connection Density is high.
