Umbrella leaf 1 is fixed in the proximal end stated and distal end is fixed umbrella leaf 3 and is compressed into than without the small ring to external bulging of diameter under outer force effect
Shape.
2 the utility model of embodiment without conducting wire pacemaker system
Fig. 3-5 is referred to, Fig. 3 is to be released position schematic diagram of the utility model without conducting wire pacemaker system, and Fig. 4 is this reality
With half release position schematic diagram of novel no conducting wire pacemaker system, Fig. 5 is the utility model releasing entirely without conducting wire pacemaker system
Put a schematic diagram.It is described without conducting wire pacemaker system equipped with no conducting wire pacemaker fixing device 100, without conducting wire pacemaker 200,
It is fixedly connected with component 300, push rod 400 and transmission sheath 500.It is described without such as 1 institute of embodiment of conducting wire pacemaker fixing device 100
It states.The distal end without conducting wire pacemaker 200 is fixed umbrella leaf 1 with the proximal end of no conducting wire pacemaker fixing device 100 and is connect admittedly
It is fixed, no conducting wire pacemaker 200 proximally by being fixedly connected with component 300 and the distal end of push rod 400 is connected and fixed.Full release position
Under state, 2 outer diameter of umbrella handle of the no conducting wire pacemaker fixing device 100 is identical as no 200 outer diameter of conducting wire pacemaker.It waits releasing
Put under a state, the no conducting wire pacemaker fixing device 100, without conducting wire pacemaker 200, be fixedly connected component 300 and
The distal end of push rod 400 is in the cavity of transmission sheath 500.
The application method without conducting wire pacemaker system of the utility model is：In art, the sense of puncture site is tested first
To know and pacing threshold, the laggard having sexual intercourse of Parameters satisfactory/interventricular septum punctures, and after success, epitheca is sent into the left heart by guide wire,
Then transmission sheath 500 of the utility model without conducting wire pacemaker system is sent along epitheca to distal end, operation push rod 400 will be remote
The fixed umbrella leaf 3 in end and umbrella handle 2 are pushed out to the outside of transmission sheath 500, then pull back epitheca and transmission sheath 500 to the right heart, keep distal end solid
Determine umbrella leaf 3 to be close to continue nearly to hold fixed umbrella leaf 1 after on the left of room/interventricular septum and be pushed out to transmission sheath 500 without conducting wire pacemaker 200
Outside, measure discharge pacemaker after threshold of perception current satisfaction again, postoperative can will fix in art or without conducting wire pacemaker in short term
Device 100 and without conducting wire pacemaker 200 retract transmission sheath 500 withdraw resetting.
For above example, it should be noted that " distal end " be instrumentation state under apart from patient farther out
One end, " proximal end " is then one end closer apart from patient under instrumentation state.The utility model rises without conducting wire
Device fixing device 100 of fighting is made of elastic memory wire, and global shape can be limited in push rod 400, can also become
The state of both ends umbrella Intermediate Gray umbrella handle is turned to, therefore left atrium/room is placed into combination with atrial septum or interventricular septum centesis,
It will stablize without conducting wire pacemaker 200 and fix, and realize auricular pacemaking or Electrophysiological mapping is combined to realize His' bundle pacing, reduce nothing
Postoperative dislocation rate in conducting wire pacemaker art changes and is only capable of Single Cardiac Ventricle pace-making and apex of right ventricle without conducting wire pacemaker in the prior art
The present situation of pace-making reduces the excessively high occurrence probability for leading to heart failure of ventricular pacemaking ratio.Under full release position state, the proximal end is solid
Determine the fixed umbrella leaf of umbrella leaf 1 and distal end 3 be umbrella, cylindric or important actor shape, fixed effect it is more reliable.The umbrella handle 2
Outer diameter is designed to consistent with no 200 outer diameter of conducting wire pacemaker under full release position state, can farthest reduce dislocation machine
Meeting.The push rod 400 and transmission sheath 500 is for realizing no conducting wire pacemaker fixing device 100 and without conducting wire pacemaker
200 implantation, release is fixed and withdraws resetting, is realized particular by the push or pull back of push rod 400.The nothing is led
Line pacemaker fixing device 100 is made of impermeable X-ray material, therefore its specific location of observable in entire surgical procedure,
Guided operation operates.The length of the umbrella handle 2 fixes the fixed umbrella leaf 3 of umbrella leaf 1 and distal end and umbrella handle without proximal end under outer force effect
2 distance is best with specification provided by the invention, and under the specification, the fixed effect of the no conducting wire pacemaker 200 is more
Significantly, pace-making effect is more excellent, therefore is not construed as this field conventional technical means.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvement and supplement without departing from the principle of this utility model, these are improved and supplement
Also it should be regarded as the scope of protection of the utility model.
