The specific embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
What provide as accompanying drawing 1 is this Double-sacculus catheter structure that the present invention relates to, it is characterized in that: it comprises two two joint connection tubes 1 that are provided with foley's tube A, the foley's tube B of balloon-expandable 7 and connect two foley's tube branched pipes 12, and save described two the triple channel cock 2 that is provided with between connection tubes 1 with check valve 3, consisting of thus to subside to fracture simultaneously locates to carry out the Double-sacculus catheter structure of two-side synchronous expansion.
By to the controlling of the triple channel cock 2 of check valve 3, both can realize the expansion of single foley's tube in use, also can be simultaneously the expandable balloon 7 that is divided into two ball ductus bursae ends be completed simultaneously the injured bone cavity that subsides is implemented the bilateral expansion.
What accompanying drawing 3 provided is the local enlarged diagram at balloon expandable position, and foley's tube wherein comprises a balloon-expandable 7, also comprises outer catheter 6, is placed through flexible hollow inner catheter 9 and Y type link 11 in outer catheter; The branched pipe that is connected with described connection tube 1 12 of Y type link 11 consists of a closed channel with outer catheter 6, inner catheter 9 and balloon-expandable 7, it is characterized in that: the one section outer catheter 6 that is positioned at the balloon-expandable district is provided with several through holes 8; Described through hole 8 is pressed adjacent 90 ° of angle spreads on outer catheter 6 bodys, and every two adjacent through holes 8 are not in the same cross section of body.
Adopt above-mentioned this mode to design lead to the hole site, the outer catheter itself of mainly considering actual use be bore in the thin walled hose of 2-3mm, the length that needs to arrange the body of " through hole " is only having 12-15mm.If through hole is formed a line, is arranged on a side of body, not only can cause the left and right army of inflation to claim, the more important thing is flexural deformation or the fracture that can cause conduit.Therefore when adopting the technical program: with through hole 8 on outer catheter 6 bodys by adjacent 90 ° of angle spreads, and every two adjacent through holes 8 arrange on outer catheter 6 that the stressed of this section body of through hole 8 is balanced not in the same cross section of body the time.Be a plurality of " through holes " that " ten " word is laid staggeredly and can not only make that the sacculus body is balanced to expand, nor can cause abnormal deformation or the damage of outer catheter 6; Simultaneously also can overcome a plurality of through holes of strip existing number of drawbacks is set.
Operator's hands is used the port of check valve 3 one ends of syringe one class air extractor connecting tee road cock 2, starting the air extractor piston takes out balloon-expandable 7 and outer catheter 6 Airs, make balloon-expandable 7 become the state of tightening, in order to enter the working region by service aisle smoothly.Entering vertebral body inside, hand-held Y type link 11, send into gently service aisle, observe the position that on conduit, labelling 5 judgement conduits enter, simultaneously also observable is arranged on outer catheter 6 or inner catheter 9, is positioned at the position of radiation sign platinum ring 5 thoroughly, balloon-expandable 7 inside, guarantee two thoroughly radiation sign stretch out service aisle fully, it is inner that whole balloon-expandable 7 is in the operative site scope.Use pressure apparatus with graduation apparatus to the interior slow injection contrast agent of balloon-expandable 7 by the port of individual event valve 3, treat that balloon-expandable 7 is slowly expansion-molded, prop up gradually fractured vertebral body.Because the present invention utilizes on outer catheter 6 the outside output contrast agent of through hole 8 that arranges, therefore can make with the balloon-expandable utricule of through hole 8 perpendicular directions and expand to fractured vertebral body section, when this expansion reaches ideal height, fractured vertebral body is synchronously propped up.Then again with find time contrast agent in balloon-expandable 7 of pressure apparatus, make balloon-expandable 7 be in the state of tightening, by the service aisle withdrawing device, after device is extracted out, stayed the cavity of a shaping in vertebral body, be convenient to carry out next step locating therapy program.
This new construction by several through holes 8 of setting on the one section outer catheter 6 that is positioned at the balloon-expandable district, compare with existing logical function ZL200620041715.2 patent, its maximum advantage is: make balloon-expandable at first to expanding perpendicular to the direction of outer catheter by these through holes, and balloon structure that can be as the ZL200620041715.2 patent shown in: very easily at first to the axis direction expansion along outer catheter.The change of this at first expansion direction not only can with the human spine that sustains damage or compress directly, ideal resets, and can avoid due to the longitudinal dilatation phenomenon in advance that adopts the balloon structure shown in the ZL200620041715.2 patent to cause, because the generation of this longitudinal dilatation can make lateral magnification reduce, the effect that resets can not be effectively played, the failure of operation might be caused.Just because of above-mentioned two innovative technologies of the technical program employing, so just make the present invention overcome the familiar lacunas of prior art.
