Abstract
The invention discloses a vertebral body expansion balloon catheter comprising a balloon, an outer tube, an inner tube and a support guide wire; a near-end of the balloon is fixed on an outer wall of the outer tube; the outer tube is communicated with the balloon and pressurizes for the balloon; the inner tube is installed inside the outer tube in a penetrating mode; the inner tube comprises a straight section and a far-end flexible bending section; the flexible bending section extends out from the outer tube and is fixedly connected with the far-end of the balloon; the support guide wire is slidingly contained inside the inner tube; the flexible bending section is kept straight when the support guide wire is inserted and returns bent when the support guide wire is extracted. The flexible balloon structure can effectively support a vertebral body cavity by expanding the balloon, and vertebral body height can be well restored by inserting one-side balloon conduit. Besides, the continuous control of the degree of curvature of the balloon can be achieved by controlling the degree of extraction of the support guide wire from the flexible bending section and associated control devices.
Description
Technical field
The present invention relates to medical instruments field, espespecially a kind of balloon catheter for expanding vertebra.
Background technology
Vertebral fracture can cause the dysfunction pain of periods of months, and this pain can make patient disability
And motor capacity, can promptly cause forfeiture, pulmonary atelectasis and pneumonia, the formation of deep venous thrombosis and the pulmonary infarction of limb function
Etc. fatal complication, compression fracture of vertabral body was also that a lot of life of elderly person can not be taken care of oneself and be lost independent living ability in the past
The reason for.Using substantial amounts of Drug therapy, usually cause poisonous side effect of medicine and drug dependence, patient does not receive or not mostly
It is resistant to surgical operation therapy.Mainly there are two kinds of operation means at present for the disease.
One be vertebroplasty clinic full name be percutaneous vertebroplasty (percutaneous vertebro
Plasty, PVP), belong to Minimally Invasive Surgery, by doing the otch of an about 2mm at patient back, supervised in x-ray with special puncture needle
Vertebral body is entered through skin penetrating under shield, service aisle is set up, stable fracture vertebral body in bone cement or artificial bone injection vertebral body prevents
Only subside further, hence it is evident that alleviating pain.Two be percutaneous kyphoplasty (percutanouskyphoplasty,
PKP), it is to first pass around after balloon expandable obtains vertebral body cavity to inject bone cement by several times again, stays after one side balloon expandable
Spongy bone around cavity is compacted, and has artificially manufactured the barrier of a prevention bone cement seepage；On the other hand push rod is used
By several times the more traditional compression pump of injection bone cement persistently injects pressure when greatly reducing bone cement injection, therefore bone cement
Seepage greatly reduces.This has percutaneous kyphoplasty (percutanouskyphoplasty, PKP) to have possessed relatively
Good application prospect.
In practical application, PKP is typically by the way of bilateral balloon expandable, and this wound to patient is big, complication occurs machine
Meeting is high, financial burden that is increasing patient, and the operation process more loaded down with trivial details time is longer, damages bigger, physical fitness requirement to the health of doctor
Higher.A solution is urgently proposed, only needs unilateral balloon expandable dilating sacculus system can be sent into vertebral body central part
Position, realizes recovering the effect of vertebral height well.By the improvement for balloon catheter for expanding vertebra structure effectively to realize
The bending of sacculus, enables sacculus preferably to reach the middle position of vertebral body, is a technical barrier urgently to be resolved hurrily.
Content of the invention
It is an object of the invention to provide a kind of balloon catheter for expanding vertebra, effectively realizes the bending of sacculus.
The technical scheme that the present invention is provided is as follows：A kind of balloon catheter for expanding vertebra, including sacculus, outer tube, inner tube and
Seal wire is supported, the balloon proximal is fixed on the outer tube outer wall, the outer tube is turned on as its pressurising with the sacculus；Described
Inner tube is located in the outer tube, and said inner tube includes the flexible bending tune of straightway and distal end, outside the flexible bending tune
Stretch and pass the outer tube and be fixedly connected with the distal end of the sacculus；The support seal wire slides and is placed in said inner tube.
Wherein, the flexible bending tune maintains rectilinear form when the support seal wire is plugged, and in the support seal wire
Recover curved shape during extraction.
First, its foley's tube of maintenance is limited generally by supporting seal wire to carry out shape for the flexible bending tune of inner tube
Straight line, so normally microtrauma puncture can enter in vertebral body.
Secondly, when supporting seal wire progressively to extract out from inner tube flexible bending tune, curved shape will be recovered in the part of extraction,
Sacculus is driven with conjugating therewith, sacculus can be driven to enter vertebral body central part.Effect has four, the suitable space bit of the first
Put and allow balloon expandable more effectively to strut vertebral body cavity, its two can be achieved on unilateral foley's tube insertion i.e. can be relatively
Good recovery vertebral height, which three is that flexible bending tune recovers due to supporting seal wire progressively can extract out from flexible bending tune
The degree of shape also has therefore variant, can continuously be controlled for the position of the final expansion of sacculus, also thus control
Sacculus angle of bend, it is achieved that the directed expansion of sacculus.Its four be by the use of place support seal wire inner tube as drive sacculus
The part of bending, controls sacculus degree of crook by seal wire pull, does not affect the effect of balloon expandable pipeline, and practical operation
In also easily convenient, structure to realize difficulty not high yet.
Preferably, the expandable part of the sacculus is located at the flexible bending tune surrounding side.Can so avoid the sacculus can
Larger traction force is received when expansion is located on flexible bending tune and straightway respectively so that the more stable expansion of the maintenance of sacculus
State, distribution of force is more uniform.
Preferably, the flexible bending tune be shaped as c-type or L-type.Flexible bending tune can be with curve form or folding
Line form is to vertebral body central bend.
Preferably, the sacculus is combined by several spherical form parts being mutually conducted and is constituted.Sacculus is some spherical
The sugarcoated haws on a stick shape of shape composition, can improve force-bearing situation during balloon expandable, when especially flexible bending tune is curve shape.
Preferably, the flexible bending tune is sweat soldering with the connected mode of the balloon distal.
Preferably, the balloon catheter for expanding vertebra also includes developing ring, and the developing ring is arranged on the flexible bending
Section.
Further, the balloon catheter for expanding vertebra also includes Y-connector, and the Y-connector includes Y type
Body, needleless joint；The Y-piece body include line part and from the straight line portion expenditure sidepiece, the two of the line part
End is respectively arranged with first interface and second interface, and the overhanging one end of the sidepiece is provided with the 3rd interface, and the first interface faces
