Abstract
The utility model relates to an implanted cardiac pacemaker. An epoxy resin top is molded at the top end of a pulse generator of the implanted cardiac pacemaker, and a penetrating leading wire and a connecting body are positioned in the epoxy resin top. Besides, screw holes and a seal cavity are longitudinally molded on the epoxy resin top, and an electrode conduit pipe cavity is transversely molded on the epoxy resin top. When the utility model is used in a clinical operation, an electrode conduit pipe plug at one end of a sheathed electrode conduit pipe is inserted into the electrode conduit pipe cavity to ensure that the electrode conduit pipe plug is tightly connected with the connecting body and then is well fixed by screw nails, and a sealing plug is inserted into the seal cavity. Thus, the reliable connection is guaranteed, the electricity conducting performance is favorable, but also the reliable seal is guaranteed, and the functions of the cardiac pacemaker is effectively realized.
Description
This utility model relates to a kind of implantable cardiac pacemaker, belongs to electronic medical equipment manufacturing technology field.
The implantable cardiac pacemaker is made up of pulse generator and electrode catheter two parts, the pulse signal of pulse generator granting transfers to heart and cardiac stimulus pace-making via electrode catheter, the exciting signal of heart also is sent to cardiac pacemaker by electrode catheter, therefore, electrode catheter must connect into an integral body with pulse generator and can use, the metal shell of cardiac pacemaker pulse generator is an electrode, and electrode catheter is another electrode.And seal weld connects later pulse generator, being exposed to enclosure as the leadthrough of pulse generator negative pole can't be connected with electrode catheter, adopt which type of structure that two parts device is linked into an integrated entity, and the sealing between warrantor's body fluid and cardiac pacemaker pulse generator housing and the leadthrough, being effective the function that realizes cardiac pacemaker, is the difficult problem that urgency is to be solved.
The purpose of this utility model is to design a kind of implantable cardiac pacemaker, by molded epoxy resin top has solved this difficult problem at its top cover place, pulse generator top.
This utility model design: a kind of implantable cardiac pacemaker, form by pulse generator (1) and electrode catheter (2), one end of leadthrough (3) is fixed on the lead terminal (4) of pulse generator (1), the other end is fixed on the connector (5), vertically be shaped on screw (7) on the connector (5), laterally be shaped on jack (8), and screw (7) connects with jack (8), be installed with screw (9) on the screw (7), the top of pulse generator (1) is molded with epoxy resin top (6), and leadthrough (3), connector (5) is positioned at epoxy resin top (6), in addition, vertically be molded with screw hole (10) on the epoxy resin top (6), annular seal space (11), laterally be molded with electrode catheter chamber (12), and screw hole (10) communicates with screw (7), and annular seal space (11) is positioned at the middle part of screw hole (10), and the left part of electrode catheter chamber (12) and right part connect by jack (8).
Epoxy resin top (6) is the transparent body.The geomery in electrode catheter chamber (12) can according to the corresponding plug geomery correspondence of supporting different model electrode catheter molded.
Advantage that the utlity model has and effect: the good biocompatibility of epoxy resin, can not cause organ rejection episodes, and good mechanical property, can with titanium case surface strong bond.Simultaneously owing in the epoxy resin top, preset leadthrough, connector when molded, molded electrode catheter chamber, annular seal space, the electrode catheter plug of electrode catheter one end that only need will match when therefore clinical operation is used inserts the electrode catheter chamber, making the electrode catheter plug closely be connected and be screwed with connector gets final product, and sealing-plug inserted annular seal space, and both guaranteed to connect reliable, the conductivity performance is good, guaranteed that again sealing is reliable, effectively realized the function of cardiac pacemaker.
Fig. 1 is a structural representation of the present utility model.
1 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of implantable cardiac pacemaker, form by pulse generator (1) and electrode catheter (2), one end of leadthrough (3) is fixed on the lead terminal (4) of pulse generator (1), the other end is fixed on the connector (5), vertically be shaped on screw (7) on the connector (5), laterally be shaped on jack (8), and screw (7) connects with jack (8), be installed with screw (9) on the screw (7), the top of pulse generator (1) is molded with epoxy resin top (6), and leadthrough (3), connector (5) is positioned at epoxy resin top (6), in addition, vertically be molded with screw hole (10) on the epoxy resin top (6), annular seal space (11), laterally be molded with electrode catheter chamber (12), and screw hole (10) communicates with screw (7), and annular seal space (11) is positioned at the middle part of screw hole (10), and the left part of electrode catheter chamber (12) and right part connect by jack (8).
Epoxy resin top (6) is the transparent body.The geomery in electrode catheter chamber (12) can according to the corresponding plug geomery correspondence of supporting different model electrode catheter molded.
When clinical operation is used, according to the clinical treatment needs, select the applicable model cardiac pacemaker, program to specifications, the electrode catheter plug of electrode catheter one end that will match inserts the electrode catheter chamber, make the electrode catheter plug closely be connected and be screwed and get final product, and sealing-plug is inserted annular seal space carry out the screw hole sealing with connector.
Claims (3)
1, a kind of implantable cardiac pacemaker, form by pulse generator (1) and electrode catheter (2), one end of leadthrough (3) is fixed on the lead terminal (4) of pulse generator (1), the other end is fixed on the connector (5), vertically be shaped on screw (7) on the connector (5), laterally be shaped on jack (8), and screw (7) connects with jack (8), be installed with screw (9) on the screw (7), it is characterized in that: the top of pulse generator (1) is molded with epoxy resin top (6), and leadthrough (3), connector (5) is positioned at epoxy resin top (6), in addition, vertically be molded with screw hole (10) on the epoxy resin top (6), annular seal space (11), laterally be molded with electrode catheter chamber (12), and screw hole (10) communicates with screw (7), and annular seal space (11) is positioned at the middle part of screw hole (10), and the left part of electrode catheter chamber (12) and right part connect by jack (8).
