8. a kind of working method of cardiovascular interposing catheter device as claimed in claim 1, which is characterized in that including following
Step：
S1：To disease affected part, angiocardiography is done, is determined at sufferer, and carries out the early-stage preparations of normal interventional treatment；
S2：Thrombolytic agent is injected into feed liquor storehouse (312), and installs propeller one (313), by pushing propeller one
(313) air in liquid-transport pipe-line is emptied, until waiting for that liquid is oozed out from fluid apertures (111), pricker is detected by line wheel one (321)
Whether device (12) is normal, detection method：Stir to the right line wheel one (321) one of them, observation catheter head (1) is close to dialling
Whether the Z-type needle (121) of moving-wire wheel one (321) side pierces out, unclamps stirred line wheel one (321) and observes the Z-type needle pierced out
Whether withdraw in catheter head (1), detects whether steering gear (13) steering is normal, and detection method is by line wheel two (323)：To
The right side stir line wheel two (323) one of them, whether observation catheter head (1) to stirred line wheel two (323) lateral bend；
S3：Conduit is stretched into from incision, and is slowly pushed by conduit propulsion device (4), when conduit needs to turn to, is passed through
Line wheel (331) adjusts steering gear (13), when catheter head (1), which is met, blocks blood vessel, can tighten steel wire by line wheel (331)
One (23) make Z-type needle (121) pierce out, then so that thrombolytic agent is oozed out from fluid apertures (111) by propeller one (313), work as conduit
When head (1) passes through narrow blood vessel, air bag (25) increase release holder is made by propeller two (332), waits for that holder installs
Adjusting propeller two (332) makes air bag reduce, and so that conduit is exited patient's body by conduit propulsion device (4).
9. a kind of cardiovascular interposing catheter device as claimed in claim 5, which is characterized in that the gear one (42), tooth
Two (44) of wheel, gear three (43) are connected through a screw thread respectively with conduit.
