The specific embodiment
As shown in Figure 2, a kind of implantable cardiac pacemaker hormone screw electrode conduit, it adopts coaxial dipolar configuration.Ring electrode 4 by the bipolar connector 1 that connects with cardiac pacemaker, the electrode spiral conducting line body 3 that coats the transmission of electric signals of medical grade rubber insulating barrier 2, perception and stimulation cardiac muscle is formed with screw electrode head 6 and hormone bolt (dexamethasone sodium phosphate) 5.Electrode spiral conducting line body 3 adopts double-layer coaxial spring leads and insulating barrier to form and is communicated with bipolar connector 1, ring electrode 4, electrode tip 6 welding, between the two-layer spring lead by silica gel tube insulation isolation.Hormone bolt 5 is housed in the electrode tip 6.Its electrode head end gets into the atrium through Venous system, and its bipolar connector end has been connected to the heart device interface of fighting.Leaning on electrode head end wire body is J-shaped, help finding in the atrium preferably the position and through the reversal of the natural order of things of anchor shape silicone rubber at myocardium girder, electrode tip is close to myocardial surface, passive fixing, and have hormone to discharge; The intravital two coaxial springs leads of its electrode spiral conducting line, one is sent to heart with pacemaker impulse, and one sends back pacemaker with heart self electrocardiosignal.
The electrode tip 6 of implantable cardiac pacemaker J-shaped hormone bipolar electrode conduit, ring electrode 4 adopts the platinumiridio material also to cover the TiN coating, and the double-layer coaxial spring lead of electrode spiral conducting line body 3 adopts four of MP35N alloy silks and around forming.
Implantable cardiac pacemaker J-shaped hormone bipolar electrode conduit is passive fixing and have hormone to discharge through the Venous system implant into body; It forms electronic loop through connecting with implantable cardiac pacemaker, cardiac muscle, and the realization cardiac pacemaker is directly treated cardiac's arrhythmia, bradycardia symptom effectively to human ecg signal detection senses and pulsed discharge stimulation therapy function.Its perception and stimulatory function are respond well, simultaneously through hormone discharge make at electrode tip and organizational interface possibly damage, inflammation is relieved to minimum level, almost can eliminate the characteristic that non-hormone discharges the rising of electrode catheter initial threshold.Because the smooth transition of hormone electrode catheter system from the acute stage to the chronic phase makes the patient generally tangible threshold fluctuations can not occur.
This utility model its behind the whole implant into body of Venous system, the atrium is passive fixing and have hormone to discharge; It forms electronic loop through connecting with implantable cardiac pacemaker, cardiac muscle, and the realization cardiac pacemaker is directly treated cardiac's arrhythmia, bradycardia symptom effectively to human ecg signal detection senses and pulsed discharge stimulation therapy function.Its perception and stimulatory function are respond well; And can solve initiatively fixing inadaptation of screw electrode ventricle; Simultaneously through hormone discharge make at electrode tip and organizational interface possibly damage, inflammation is relieved to minimum level, almost can eliminate the characteristic that non-hormone discharges the rising of electrode catheter initial threshold.Because the smooth transition of hormone electrode catheter system from the acute stage to the chronic phase makes the patient generally tangible threshold fluctuations can not occur.Simultaneously bipolar operation does not also have amyostasia and produces, and is to use very directly effective technical means of implantable cardiac pacemaker treatment cardiac arrhythmia, bradycardia symptom, saves and improves cardiac's life and quality of life, and is safe and effective.
This utility model fabrication scheme is realized through following steps:
1), select for use suitable metal material to make connector (monomer is bipolar) with biocompatibility; Select platinumiridio material electrode tip, ring electrode for use and cover the TiN coating; Select four of MP35N alloy silks for use and isolate by the silica gel tube insulation around forming between the double-layer coaxial spring lead (monomer twin-core) of making electrode spiral conducting line body, the two-layer spring lead; 2), the use medical grade silicon rubber is suppressed the silica gel connector, and is adopted sulfuration process to assemble shaping for electrode cable body coated insulation layer and whole connection of electrode catheter; 3), test detects; 4), clean the back surface-coated; 5), clean back sterilization, packing again; 6), check and put in storage for use.
The method for using of this utility model:
This implantable cardiac pacemaker hormone screw electrode is passive fixing cord, leans on electrode head end lead to become J-shaped, during implantation; The doctor penetrates a harder steel wire in electrode cable, temporarily make electrode cable stretch and be beneficial to through vein, after electrode cable puts in place; Drawing back steel wire makes electrode cable recover J-shaped; So that the contact atrial walls, at myocardium girder arteries and veins, accomplish the lead location through the reversal of the natural order of things of anchor shape silicone rubber.
When the doctor uses at clinical operation; By operation instructions requirement of implantable cardiac pacemaker and relevant art parameter identification; The implantable cardiac pacemaker is gone into human body with the implant surgery heeling-in; And with this electrode catheter connecting circuit reliable system with it; Regulate technical parameter according to different patient individual differences its cardiac pacing therapy and the program control completion of parameter of beginning to carry out signs of arrhythmia all performed the operation, and according to treatment content and target through perform the operation the back periodically check follow up a case by regular visits to and adopt the adjustment of vitro program controlled method that suitable technical parameter is set, reach final signs of arrhythmia patient's heart pacing therapy functional effect.
