Description
[technical field]
The present invention relates to technical field of medical instruments, be specifically related to a kind of Implanted cardiac pacemaker electrode cable the most solid
Fixed structure.
[background technology]
Implanted cardiac pacemaker electrode cable is different according to fixed form, can be divided into passive fixing and actively fix two
Kind, passive fixed electrode wire can only be confined to traditional cardiac pacing position, such as right auricle and right ventricular apical, and leads
Dynamic fixed electrode wire is in addition to may be used for traditional cardiac pacing position, it is also possible to for other positions, such as room
Every, right ventricular outflow etc..The most actively fixed electrode wire is when implanting, and often occurs fixing head cannot to screw out or revolve
Going out dumb, electrode cable bore seal the most sternly causes the phenomenons such as electric pole short circuit, adds the difficulty of operation.
Therefore, it is necessary to provide a kind of new Implanted cardiac pacemaker electrode cable actively fixed structure.
[summary of the invention]
