Description
Technical field
The utility model belongs to medical device field more particularly to a kind of thrombectomby system.
Background technology
It is clinically general bolt to be taken to be treated with machinery using drug thrombolysis for embolism lesion, since drug thrombolysis is tight
Time window limitation and the more complication of lattice, most of patient can take the mechanical therapeutic modality for taking bolt.
Existing machinery takes bolt all to have a disadvantage that substantially：The patch being likely to occur during thrombectomby comes off or blood
Distal end " rubbish foot " caused by stud portion comes off, is caused after taking bolt, the thrombus fragment to come off cannot recycle completely to be excreted, can
It can cause pulmonary embolism.Therefore a kind of machinery is needed to take pin device that can effectively release the spot being likely to occur during thrombectomby
Block come off or thrombus partial exfoliation caused by distal end " rubbish foot ", the flowing of thrombus fragment is avoided to form new thrombus, reinforcement pair
The interception of thrombus, reduces the generation of pulmonary embolism, while improves thrombus fragment elimination efficiency and safety.
Utility model content
In order to solve the disadvantage that the prior art, the purpose of this utility model is to provide a kind of thrombectomby system, the system
The possibility that patch comes off or thrombus partial exfoliation causes distal end " rubbish foot " to occur during thrombectomby can be avoided, improves blood
Bolt fragment elimination efficiency and safety.
A kind of thrombectomby system of the utility model, including atherectomy catheter, microtubular and elastic filter screen；
