Description
Technical field
The present invention relates to a kind of device that is used for minimally-invasive treatment collapse of vertebra and compression fracture, particularly disclose a kind of balloon dilatation catheter that is used to treat compression fracture of vertabral body.
Background technology
Compression fracture of vertabral body (VCF) is a kind of common spinal injury and can causes long term disability, and in general, compression fracture of vertabral body (VCF) relates to subsiding of one or more vertebral bodys in the spinal column.Compression fracture of vertabral body (VCF) is unobstructed to occur in the bottom vertebral body of thoracic vertebra or the top vertebral body of lumbar vertebra.Compression fracture of vertabral body (VCF) is usually directed to the fracture of the front part generation of influenced vertebral body.Compression fracture of vertabral body (VCF) can cause normal sequence and the curvature of the vertebral body in the involved area of spinal column, and for example lordosis produces distortion.Compression fracture of vertabral body (VCF) and/or relevant deformity of spine for example be since the metastatic disease of spinal column, wound etc. cause or relevant with osteoporosis.Up at present, the doctor still is subject to many limitations aspect lopsided with relevant taking which kind of mode to treat compression fracture of vertabral body (VCF).The treatment compression fracture of vertabral body generally adopts vertebroplasty (PVP) or kyphoplasty art (PKP).
At the existing device that is used for treating compression fracture of vertabral body; Double-layer tube commonly used connects and the balloon expandable body connects and composes; And the formation of this double-layer tube is by deriving on the angiocarpy sacculus, and this structure of double-layer tube has become a kind of fixed structure and the current techique in present technique field, therefore; Follow-up improvement for the device that is used to treat compression fracture of vertabral body is all carried out with " double-layer tube " this basis; Usually this type of conduit is formed by connecting complex structure, higher relatively difficulty of processing in interior pipe conduit and sacculus.Like application number is 200620041715.2, the utility model patent of " vertebral body expansion of balloon catheter " by name, and its conduit is divided into inner catheter and outer catheter; Application number is 201110171046.6, and the application for a patent for invention of " vertebral body directed expansion foley's tube " by name is provided with the orienting cover pipe outside conduit; In order to make conduit smoothly the balloon expandable body to be realized expanding after arriving the target location, all must support conduit and sacculus by Y type connector and support seal wire, the shortcoming of this kind structure is that adnexa is more, the processing complex connection.
Summary of the invention
The objective of the invention is to overcome the defective that exists in the prior art, provide a kind of sound construction, simple, easy to use being used to of processing to treat the balloon dilatation catheter of compression fracture of vertabral body.
The present invention is achieved in that a kind of balloon dilatation catheter that is used to treat compression fracture of vertabral body; Comprise balloon expandable body, conduit, development ring; It is characterized in that: said conduit is the monolayer conduit; One end of said conduit is the cavity link, and said cavity link and said balloon expandable body opening are connected as a single entity or said cavity link stretches in the said balloon expandable body with the balloon expandable bulk phase and connects, and the other end of said conduit is an opening.
The external diameter of said conduit is 2mm-6mm, and the internal diameter of said conduit is 1.5 mm-4 mm.
When the cavity link of said conduit stretched in the said balloon expandable body, said balloon expandable body opening part and said conduit formed and are tightly connected, and one section conduit in the said balloon expandable body is provided with liquid injection hole.
Said conduit is provided with the prebuckling position, and said prebuckling position is positioned near balloon expandable body opening part and is positioned on the external conduit of said balloon expandable.
Said development ring is positioned on the cavity link of said conduit.
The angle of bend at said prebuckling position is: make the axis of said catheter main body and the axis of said balloon expandable body form the angle that 120 degree-170 are spent.The setting of crooked position makes the present invention easier and convenient when pushing to targeted vertebral body.
The external shape of said balloon expandable body is any one in ball-type, spheroid shape, calabash shape or the hemispherical.
The invention has the beneficial effects as follows: said conduit adopts the monolayer conduit; The balloon expandable body one-body molded with conduit or through welding, agglutinating mode seals and links to each other, sound construction, simple, the processing and manufacturing difficulty is lower; Compare with conventional sacculus dilating catheter, save seal wire and Y type connector; For the hardness that makes conduit better reaches the purpose that supports the sacculus expansion body, the external diameter of conduit of the present invention further increases with respect to prior art, and making the whole chap of conduit correspondingly increases its wall thickness.Because foley's tube generally adopts macromolecular materials such as PU, PEBAX, nylon, this patent adopts simplified structure, removes seal wire, in order to ensure the ability of foley's tube through the position of passage arrival pathological changes, needs thickening conduit wall thickness.
