Description
Technical field
The present invention relates to the technical field of taking thrombus apparatus, and pin device is taken more particularly to a kind of balloon expandable.
Background technology
Cardiovascular and cerebrovascular blocks, and some uses thrombolysis, some using timely to linked groups come dredging vascellum the methods of taking bolt
Recover blood supply, so as to reduce dead or disability incidence, take bolt to be operated by the menisectomy that develops, it is of the prior art to take bolt instrument
Bolt instrument is taken to generally comprise the flexible steel core of inside and outside sleeve pipe, before interlayer of the spring wire between steel core and sleeve pipe
End, respectively with steel core and sleeve pipe connection, this section of sleeve pipe outside spring wire is flexible membrane at spring wire both ends, when steel core backward
During pulling, because the relative motion of steel core and sleeve pipe is discoid by spring wire compressed shape, blood vessel is scraped by the saucerspring silk
Thrombus on inwall, this kind of instrument are detected and inserted by flexible steel core front end in intravasation, and its blindness is bigger,
When running into the more complicated situation of some thrombus situations, vascular wall is easily broken in the front end of steel core, causes the accident, so this
A kind of structure for taking bolt instrument has much room for improvement.
The content of the invention
To solve the above problems, the purpose of the present invention is to propose to a kind of balloon expandable to take pin device.
Technical scheme is as follows：A kind of balloon expandable takes pin device, including is set in together inner sleeve and overcoat
Pipe, it is characterized in that：Pre-and post perforative thread eye is provided with inner sleeve, thread eye has been built into seal wire；In outer tube and inner sleeve
Front end interlayer in be provided with spring wire, the spring wire spiral winding in interior outside pipe, the both ends of spring wire respectively with outer tube
It is fixedly connected with inner sleeve, this section of inner sleeve outside spring wire uses the elastic membrane of sleeve-shaped, before the elastic membrane
Hold and be fixed together with the closing of the front end of inner sleeve；A sacculus is set with outside the inner bobbin at elastic membrane rear portion, inside
The water-filling pipeline connected with the sacculus is provided with set tube wall, valve and joint are installed in the outer end of charging pipe；
The closing clack valve with seal wire diameter matches is equipped with inner sleeve front end and afterbody；It is provided with the endpiece side wall of outer tube vertical
To strip opening, protruding in the side wall of inner sleeve corresponding to opening to have lever, lever driving inner sleeve edge
Slide axially.
Preferably, described seal wire front end is pigtail shape.
Preferably, described closing clack valve is made using elastomeric material, and seal wire can close the both ends of inner sleeve after extracting out.
The solution have the advantages that：
The balloon expandable of the invention takes pin device, there is provided seal wire and internal and external casing, so as to take bolt device to pass through seal wire this
It imported into blood vessel, because the end of seal wire is soft, blood vessel will not be damaged, can avoids breaking the thing of blood vessel
Therefore；Sacculus is added simultaneously, spring wire is responsible for removing endovascular outmoded thrombus, and sacculus is responsible for removing endovascular new formation
Thrombus, spring wire are responsible for scraping blood vessel, and sacculus is responsible for rubbing to blood vessel due to can be deformed with the shape of blood vessel
Erasing clear up, can solve some spring wires cleaning less than thrombus, the two binding operation, respectively take the chief, flexibly use, can will
The comparison of thrombus cleaning is clean.

Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention
Formula is described in further detail.
Embodiment one：Referring to Fig. 1-4, a kind of balloon expandable takes pin device in figure, including is set in together inner sleeve and outer
Sleeve pipe, pre-and post perforative thread eye is provided with inner sleeve, thread eye has been built into seal wire；In the front end of outer tube and inner sleeve
Spring wire is provided with interlayer, the spring wire spiral winding in interior outside pipe, the both ends of spring wire respectively with outer tube and inner sleeve
It is fixedly connected, this section of inner sleeve outside spring wire uses the elastic membrane of sleeve-shaped, the front end of the elastic membrane and inner sleeve
The front end closing of pipe is fixed together；A sacculus is set with outside the inner bobbin at elastic membrane rear portion, in inner sleeve tube wall
It is interior provided with the water-filling pipeline connected with the sacculus, valve and joint are installed in the outer end of charging pipe；
The closing clack valve with seal wire diameter matches is equipped with inner sleeve front end and afterbody；It is provided with the endpiece side wall of outer tube vertical
To strip opening, protruding in the side wall of inner sleeve corresponding to opening to have lever, lever driving inner sleeve edge
Slide axially, operation handle can drive inner sleeve pull to move, disk-shaped or linear so as to adjust front springs silk.
Described seal wire front end is pigtail shape.
Described closing clack valve is made using elastomeric material, and seal wire can close the both ends of inner sleeve after extracting out, clack valve
Effect is blood can be blocked to be outflowed from inner sleeve after seal wire is extracted out.
This takes the operating process of bolt device：
In use, seal wire is sent into first under development state it is intravascular, after thrombi is crossed in seal wire front end, by inner-outer sleeve
The assembly of pipe be sent to along seal wire it is intravascular, after the spring wire and sacculus of its front end cross thrombi.
The spring wire compression of front end is expanded discoid, locking by the lever pull inner sleeve that on the one hand can operate afterbody
Internal and external casing while pull, the thrombus of blood vessel is scraped with the spring wire of plate-like, until the thrombus is scraped.
On the other hand syringe can be connected by the joint of afterbody, is injected into physiological saline, sacculus be filled up to come, then
Take out simultaneously and carry out internal and external casing, filling up the sacculus come can be rubbed blood vessel, and the thrombus of the new formation of blood vessel is rubbed off；Or
Person is to become in the more irregular position of some cross sectional shapes, the shape of the sacculus with the change of the cross sectional shape of blood vessel
Change, some indelible thrombus of spring wire can be removed.
Spring wire and sacculus can also be used simultaneously, and this according to circumstances can flexibly be selected.
