Description
Technical field
The utility model is related to medical instruments fields more particularly to a kind of sacculus to take pin device.
Background technology
Because many factors can lead to the formation of thrombus in blood vessel, and then cause a series of symptoms and complication.To in blood vessel
Thrombus treatment commonly operative treatment, the step of operative treatment mostly uses greatly Catheter embolectomy, Catheter embolectomy for
The body part of the thrombosis of patient nearby cuts blood vessel, and insertion takes bolt conduit and passes through grumeleuse position along blood vessel, and bolt is taken to lead
It is provided on pipe and takes spigot for pull thrombus, take pin device to take sludged blood out of by withdrawing, it is solidifying to determine after multiplicating
Clot is cleaned.It takes in bolt conduit using sacculus as taking the first grade design that spigot is relatively conventional.
Authorization Notice No. be the Chinese utility model patent of 203468689 U of CN disclose it is a kind of it is intravascular take pin device,
This is intravascular, and to take pin device include head end, conduit, tail end and sacculus, and head end and tail end are connected to the both ends of conduit, sacculus package
In conduit at the position of near head end, conduit is two-chamber road body, and tail end includes into the female Luer and conduit of " Y shape " distribution
, it is provided with the trepanning being connected to sacculus in the conduit portion of sacculus package, seal wire is inserted in the cavity being connected to catheter block, leads
Silk is inserted into corresponding cavity by catheter block, and the both ends of another cavity of conduit are connected to female Luer, is noted from female Luer
Enter liquid, liquid is physiological saline, and physiological saline enters sacculus through the corresponding cavity in conduit, realizes the expansion to sacculus, ball
With vascular wall good fit after capsule expansion, thrombus can be completely removed when withdrawing.
But in the whole process, seal wire is first inserted into blood vessel and crosses thrombus position, takes the head end i.e. front end of pin device
It needs to send to thrombus position along seal wire, seal wire needs are pierced by from the catheter block of conduit, and when the length of conduit is longer, seal wire is very
It is difficult to be smoothly pierced by from the catheter block of tail end from head end insertion, it is inconvenient for operation, moreover, pin device is taken to be extracted out from blood vessel
When, take pin device to need entirely to extract separation out from seal wire, the length of the seal wire needed in this way is longer, and seal wire is at least greater than two
The length of a conduit can be realized, cost is increased.
