Abstract
The invention discloses a vertebral oriented dilated balloon catheter which is used in the percutaneous vertebroplasty in the field of orthopedic medical devices. The vertebral oriented dilated balloon catheter comprises a catheter, wherein a Y-shaped connector is connected to one end of the catheter, and a balloon is connected to the other end of the catheter; a probe extends into the balloon after passing through a joint of the Y-shaped connector and the catheter, and a ray label is arranged on the head of the probe; an oriented casing is sleeved outside the catheter, and a forward-protruding oriented separation blade is arranged on the head of the oriented casing; and the oriented separation blade is positioned at the outer side of the balloon. According to the vertebral oriented dilated balloon catheter with the structure, the balloon can dilate towards a preset dilation resetting direction, so that the degree of fracture injury on a vertebral body breakage part cannot be sharpened, and re-fracture is avoided.
Description
Technical field
The present invention relates to the orthopedic medical device field, refer more particularly to employed vertebral body expansion of balloon catheter in the percutaneous puncture vertebral body plastic operation.
Background technology
Compression fracture of vertabral body sickness rate in old group is higher, the compression degree difference of subsiding of fracture site vertebral body each several part, and the position big for compression degree needs distraction reduction, and injects implant such as bone cement and fill.Can increase vertebral body intensity and stability after bone cement solidifies, this has just guaranteed that restorative vertebral body can not be compressed again, can not lose vertebral height, pressuring nerve once more.
The vertebral body expansion of balloon catheter is one of treatment compression fracture of vertabral body apparatus commonly used, its structure is referring to shown in Figure 1, comprise conduit 3, one end of conduit 3 is connected with Y-connection 2, the other end of conduit 3 is connected with sacculus 5, probe 1 extend in the sacculus 5 after passing joint on the Y-connection 2 and conduit 3, and the head of probe 1 is provided with radiographic marker 4.
The using method of the vertebral body expansion of balloon catheter of said structure is: in operation, the vertebral body expansion of balloon catheter is stretched in the fractured vertebral body by the passage that gets out in advance, after treating that sacculus 5 extend into the fracture site that needs distraction reduction, the developing agent pressurization of sacculus 5 being injected certain volume makes its expansion, the vertebral body that expansible sacculus 5 will subside is progressively propped up until returning to clinical treatment requirement, and form one can be for the cavity of filling so that insert bone filler such as bone cement.
The shortcoming of the vertebral body expansion of balloon catheter of above-mentioned traditional structure is: sacculus 5 can be in no direction after by the developing agent that injects certain volume to around expand, in vertebral fracture inside, disruptive vertebral body is less and inhomogeneous to the relative pressure that sacculus 5 forms in the fracture back, sacculus 5 will be selected to expand to the less place of pressure in the pressurized expansion process, so just very likely increase the weight of the fracture and injury degree at broken position, even cause refracture, thereby increase the weight of conditions of patients.
Summary of the invention
The objective of the invention is: will provide a kind of sacculus that makes can be to the expansible vertebral body directed expansion of predefined distraction reduction direction foley's tube.
Purpose of the present invention is achieved through the following technical solutions: vertebral body directed expansion foley's tube, comprise: conduit, one end of conduit is connected with Y-connection, the other end of conduit is connected with sacculus, probe extend in the sacculus after passing joint on the Y-connection and conduit, and the head of probe is provided with radiographic marker; Be characterized in: also be set with directed sleeve pipe outside conduit, directed telescopic head is provided with the directed catch that protrudes forward, and directed catch is positioned at the sacculus outside.
Purpose of the present invention can also further realize by following technical scheme: described vertebral body directed expansion foley's tube, wherein, be provided with handle at the telescopic afterbody of orientation, and be provided with the through hole that communicates with passage in the directed sleeve pipe in the handle.
The invention has the beneficial effects as follows: the vertebral body directed expansion foley's tube that uses said structure, can regulate the position of the directed catch of orienting cover tube head by handle, the fracture site that directed catch can not be strutted blocks, developing agent to sacculus injection certain volume pressure makes its expansion then, sacculus is expanded to predefined distraction reduction direction, thereby can not increase the weight of the fracture and injury degree at broken position and avoid causing refracture.

Below in conjunction with accompanying drawing technical solutions according to the invention are described in further detail.
Fig. 1 is the structural representation of the vertebral body expansion of balloon catheter described in the background technology.
Fig. 2 is the structural representation of vertebral body directed expansion foley's tube of the present invention.
Fig. 3 is the directed telescopic structural representation described in the present invention.
Fig. 4 is that sacculus described in the present invention is to preestablishing the expansible working state schematic representation of direction.
The specific embodiment
Referring to Fig. 2, shown in Figure 3, vertebral body directed expansion foley's tube of the present invention, comprise: conduit 3, one end of conduit 3 is connected with Y-connection 2, the other end of conduit 3 is connected with sacculus 5, probe 1 extend in the sacculus 5 after passing joint on the Y-connection 2 and conduit 3, and the head of probe 1 is provided with radiographic marker 4; Also be set with directed sleeve pipe 6 outside conduit 3, the head of directed sleeve pipe 6 is provided with forward
The directed catch 7 that protrudes, directed catch 7 is positioned at sacculus 5 outsides; Afterbody at directed sleeve pipe 6 is provided with handle 8, is provided with the through hole 9 that communicates with passage in the directed sleeve pipe 6 in the handle 8.
The using method of vertebral body expansion of balloon catheter of the present invention is: in operation, directed sleeve pipe 6 is stretched in the fractured vertebral body by the passage that gets out in advance, observe the direction that needs pressurization by X-ray, regulate the position of the directed catch 7 of directed sleeve pipe 6 heads by handle 8, the fracture site that directed catch 7 can not be strutted blocks, sacculus on the conduit 35 is extend into the fracture site of need distraction reduction from directed sleeve pipe 6 after, by another joint on the Y-connection 2 the developing agent pressurization that sacculus 5 injects certain volume is made its expansion, sacculus 5 is expanded to predefined distraction reduction direction---referring to shown in Figure 4, the vertebral body that to subside is progressively propped up until returning to clinical treatment requirement, and form one can be for the cavity of filling so that insert bone filler such as bone cement, thereby can not increase the weight of the fracture and injury degree at broken position, and avoid causing refracture.
Claims (2)
1. vertebral body directed expansion foley's tube, comprise: conduit, an end of conduit is connected with Y-connection, and the other end of conduit is connected with sacculus, probe extend in the sacculus after passing joint on the Y-connection and conduit, and the head of probe is provided with radiographic marker; It is characterized in that: also be set with directed sleeve pipe outside conduit, directed telescopic head is provided with the directed catch that protrudes forward, and directed catch is positioned at the sacculus outside.
