Description
Technical field
The utility model is related to medical instruments fields, and in particular to a kind of air bag plugging device.
Background technology
Ureter stone operation relies on intracavitary minimal invasive techniques to crush or take out substantially at present, and common operation method includes
Ureteroscope combination Ho.YAG laser lithotripsy technology.In the operation of the broken calculus of ureter, calculus is easy in ureteroscope into mirror
Or moved up under the impact of flow during rubble, or even escape into kidney Meng or kidney calices, cause operative failure.To prevent
Stone debris continues deeper into human body, typically takes out rubble in time using set stone mesh basket or lithotomy forceps, or by using some
Closure takes the medical instrument of stone to extend into behind calculus, is blocked to calculus.It is existing to block the medical instrument for taking stone,
An air bag is typically arranged to be blocked.But only there are one air bag, in cracking or in the case of penetrated by Bladder stone, just
Effect can be lost, operation is influenced and carries out.
Utility model content
The utility model intends to solve the technical problem by providing a kind of air bag plugging devices, to overcome existing monosaccate to block
Device influences the defect that operation carries out under unexpected rupture event.
In order to solve the above-mentioned technical problem, the utility model uses following technical solution：
A kind of air bag plugging device, including handle and the conduit that is installed on the handle, the conduit includes hollow
Inner tube and the high molecular material outer layer being laid in said inner tube, the handle end opening of said inner tube, the patient end far from handle
Closing；The high molecular material outer layer is having one section of interruptive area at patient end, and at least two are equipped at the interruptive area
The expansible compressing gasbag being arranged in order, said inner tube are equipped with the opening corresponding to each air bag.
Preferably, said inner tube is made of Nitinol.
Or it is preferred, said inner tube is made of flexible silica gel or latex material.
Further, the outer diameter of a diameter of 0.1~0.4mm of said inner tube, the conduit are 0.5~0.9mm.
Preferably, the material of the expansible compressing gasbag is medical grade rubber or Heveatex or memory latex.
Preferably, the expansible compressing gasbag is set as 4~6.
Further, the patient end end of the conduit is equipped with high molecular material target seeker, and the length of the target seeker is
3~5mm, a diameter of 0.3~0.5mm, and there is smooth end face.
Further, the handle end opening of said inner tube is equipped with the interface for connecting air source.
The beneficial effects of the utility model：By being arranged in order multiple expansible compressing gasbags of setting, can perform the operation
The subsequent ureter of calculus is effectively blocked in journey, avoiding, which influences operation because of single balloon rupture, carries out, and goes forward side by side one
Step improves plugging effect.Meanwhile the inner tube material of conduit is by Nitinol or flexible silica gel or latex material system
At, and diameter is very thin, and patient end end is equipped with high molecular material target seeker, can when encountering ureter wall bendable, keep away
Exempt to damage ureter wall, and play guide function, conduit is made to be easier to enter ureter.
Description of the drawings
Fig. 1 is the structural schematic diagram of the air bag plugging device preferred embodiment of the utility model.
Specific implementation mode
For a further understanding of the utility model, the utility model preferred embodiment is retouched with reference to embodiment
It states, but it is to be understood that these descriptions are only the feature and advantage of further explanation the utility model, rather than to this practicality
The limitation of novel claim.
As shown in Figure 1, the air bag plugging device of the utility model, including handle 1 and the conduit 2 that is installed on handle 1.Its
In, conduit 2 includes hollow inner tube 21 and the high molecular material outer layer 22 that is laid in inner tube 21.Conduit 2 runs through entire handle
1, and it is equipped with opening in the rear end of handle；On the other hand, patient end closing of the inner tube 21 far from handle.
In conduit 2 close to one end of patient end, high molecular material outer layer 22 has one section of interruptive area, is set at the interruptive area
There are at least two expansible compressing gasbags 3 being arranged in order, corresponding inner tube 21 to be equipped with the opening corresponding to each air bag, from
And it can be ventilated by the opening at handle to make air bag expansion or shrinkage.
Preferably, the material of above-mentioned expansible compressing gasbag 3 is medical grade rubber or Heveatex or memory
Latex, quantity are set as being 4~6.Using memory latex in the present embodiment, and 6 are set as, it is adequately anti-broken to reach
Split and block effect.
Preferably, inner tube 21 is made of Nitinol；Alternatively, inner tube 21 can also be by flexible silicon
Glue or latex material are made.In this way, can meet while proof strength with good flexibility and enter demand.
Preferably, the outer diameter of a diameter of 0.1~0.4mm of inner tube 21, entire conduit are 0.5~0.9mm.
The patient end end of embodiment as a further preference, conduit 2 is equipped with high molecular material target seeker 210, institute
The length for stating target seeker is 3~5mm, a diameter of 0.3~0.5mm, and has smooth end face.To enter ureter when conduit
When, target seeker 210 can when encountering ureter wall bendable, avoid damage to ureter wall, and play guide function, make conduit
