Refer to Fig. 4, described test lead 23 comprises one first adapter 232, one second adapter 234, and the connection wire 236 of this first adapter 232 of multiple connection and the second adapter 234.Described first adapter 232 and the second adapter 234 can be plug or socket.Be appreciated that described first adapter 232 and the second adapter 234 can be plug or socket.In the present embodiment, described first adapter 232 is a plug, and described second adapter 234 is a socket.
Described first adapter 232 comprises one first insulator 2320 and multiple first metalwork 2322.The part of described multiple first metalwork 2322 fixes and is arranged at this first insulator 2320 inside, and part exposes to realize being electrically connected with described test cable 22.Described second adapter 234 comprises one second insulator 2340 and multiple second metalwork 2342.Described second insulator 2340 has a socket 2344.Described multiple second metalwork 2342 is arranged in the socket 2344 of this second insulator 2340, to realize being electrically connected with described stimulating electrode 24.Described first metalwork 2322 is identical with the quantity of described connection wire 236 with the quantity of the second metalwork 2342, and by the plurality of connection wire 236 one_to_one corresponding electrical connection.When described test lead 23 uses, described first adapter 232 inserts the socket of described test cable 22 thus is electrically connected with this test cable 22, and the non-stimulated end of described stimulating electrode 24 inserts the socket 2344 of this second insulator 2340 and is electrically connected with this second metalwork 2342.Be appreciated that described first insulator 2320 and the first metalwork 2322 are placed in when using external, it is prepared without the need to adopting biocompatible materials.Described second insulator 2340 and the second metalwork 2342 are placed in body when using, and it adopts biocompatible materials to prepare.In the present embodiment, described second insulator 2340 is silastic material, can ensure its good biocompatibility on the one hand, has certain flexibility on the other hand, effectively can adapt to human body environment.Described second metalwork 2342 is the stainless steel material of the biocompatibility of Srgery grafting.
Further, described first insulator 2320 has one first flexible transition parts 2326 near one end of described connection wire 236, and described second insulator 2340 has one second flexible transition parts 2346 near one end of described connection wire 236.Described first flexible transition parts 2326 and the second flexible transition parts 2346 are taper, semielliptical shape or hemispherical.The material of described first flexible transition parts 2326 and the second flexible transition parts 2346 is silicone rubber, can ensure good biocompatibility like this, can ensure good flexibility again.Described first flexible transition parts 2326 and the second flexible transition parts 2346 can be formed in one structure with described first insulator 2320 or the second insulator 2340, also can for be formed separately by dispensing method.It is concentrated with the junction part stress of described first insulator 2320 or the second insulator 2340 that described first flexible transition parts 2326 and the second flexible transition parts 2346 can prevent this to be connected wire 236, thus improve bonding strength and fatigue resistance, ensure the use of certain hour.Be appreciated that, this can also be connected wire 236 and seal with the junction of described first insulator 2320 or the second insulator 2340 by described first flexible transition parts 2326 and the second flexible transition parts 2346, thus can prevent when described first adapter 232 or the second adapter 234 implant, biological fluid infiltrates this first insulator 2320 or the first metalwork 2322 or the second metalwork 2342 short circuit is caused in the second insulator 2340 inside.
Described connection wire 236 comprises the insulating polymer material coating with biocompatibility that an electric wire and with biocompatibility is arranged at this electric wire outer surface.Described electric wire is tinsel or B alloy wire.The material of described macromolecule material coating can be one or more in polyurethane, silicone rubber, nylon, fluoro-containing plastic (as PTFE, ETFE etc.), Pai Lalun and polyimides.Described coating can be the multiple structure formed by the monolayer of single type material or multiple material.The quantity of described connection wire 236 is not limit, and can select as required.One end that every bar connects wire 236 extends to the first insulator 2320 inside and is electrically connected with the first corresponding metalwork 2322, and the other end extends to the second insulator 2340 inside and is electrically connected with the second corresponding metalwork 2342.In the present embodiment, there are four and connect wire 236, and every bar connects the insulating coating that wire 236 comprises a steel wire and biocompatible material.
Described multiple connection wire 236 forms twisted wire in the mode of twisted, compact and isometric to ensure many connection wires 236.Like this, when test lead 23 under tension effect, each wire 236 that connects can uniform stressed, thus improves tensile strength.Be appreciated that because the connection wire 236 in the middle of test lead 23 does not totally have the insulation protective jacket of protectiveness, easily cause many to connect wire 236 length and differ, thus when making entirety receive pulling force, connect wire 236 and only have single stressed.In order to solve the situation connecting wire 236 length and differ, the mode of twisted is utilized to form twisted wire.
Further, the insulating polymer material coating of described multiple connection wire 236 is exposed, thus after making in the plurality of connection wire 236 implantable bioartificial body, the insulating polymer material coating of this connection wire 236 can directly contact with organism.Because the plurality of connection wire 236 outside does not arrange the insulation protective jacket of accommodating the plurality of connection wire 236; the part of described test lead 23 between this first adapter 232 and second adapter 234 is made to have less external diameter; therefore; when described test lead 23 extends to organism outside from organism inside; this connection wire 236 can be made to hang out the part of organism very thin; can wound be effectively reduced, reduce the probability infected in operation process.
As shown in Figure 2, when described electric pulse stimulation test set 20 uses, can according to the symptom of patient, the outer testing stimulus device 21 of control agent.Through the stimulation of short-term, test lead 23 is taken out.If the good and patient of therapeutic effect adapts to nerve electric stimulation therapy, then implantable pulse generator and extension lead.If nerve electric stimulation therapy is not suitable for patient, taken out by stimulating electrode, the wound that the implantation avoiding on the one hand pulse generator and extension lead causes patient and the misery that extensive surgical brings, another aspect reduces the medical expense of patient greatly.
In addition, those skilled in the art can also do other changes in this utility model spirit, and these changes done according to this utility model spirit all should be included in this utility model scope required for protection.
