Abstract
The utility model discloses a balloon catheter for directional dilating of vertebras, which belongs to the field of orthopedic medical instruments and used for percutaneous vertebroplasty. The balloon catheter comprises a catheter, one end of the catheter is connected with a Y-shaped connector, the other end of the catheter is connected with a balloon, a probe extends into the balloon after penetrating through one joint on the Y-shaped connector and the catheter, ray marks are arranged at the head of the probe, a directional sleeve is sleeved outside the catheter, and a positioning retainer protruded forwards is arranged at the head of the directional sleeve and positioned on the outer side of the balloon. The balloon of the balloon catheter is capable of dilating along a preset dilating reduction direction so that injury degree of fractured portions of the vertebras cannot be increased and re-fracture is avoided.
Description
Technical field
This utility model relates to the orthopedic medical device field, refers 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, an end of conduit 3 is connected with Y-connection 2, and the other end of conduit 3 is connected with sacculus 5; Probe 1 extend in the sacculus 5 after passing joint and the conduit 3 on the Y-connection 2, and the head of probe 1 is provided with radiographic marker 4.
The method for using 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 anterior vertebral through 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 volumes is expanded it, and the vertebral body that expansible sacculus 5 will subside is progressively propped up until returning to clinical treatment requirement, and forms the cavity that can supply fill 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 through the developing agent that injects certain volume to around expand; Inner at vertebral fracture; The disruptive vertebral body in fracture back is less and inhomogeneous to the relative pressure that sacculus 5 forms, and sacculus 5 will be selected to expand to the less place of pressure in the pressurized expansion process, so just very likely increases 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 purpose of this utility model 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.
The purpose of this utility model realizes through following technical scheme: 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, and probe extend in the sacculus after passing joint and the conduit on the Y-connection, and the head of probe is provided with radiographic marker; Be characterized in: outside conduit, also be set with directed sleeve pipe, directed telescopic head is provided with the directed catch of protrusion forward, and directed catch is positioned at the sacculus outside.
The purpose of this utility model can also further realize through following technical scheme: described vertebral body directed expansion foley's tube, wherein, be provided with handle at the telescopic afterbody of orientation, be provided with in the handle with directed sleeve pipe in the through hole that communicates of passage.
The beneficial effect of this utility model is: 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 through 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.
Description of drawings
Below in conjunction with accompanying drawing the described technical scheme of this utility model is done further detailed explanation.
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 the described vertebral body directed expansion of this utility model foley's tube.
Fig. 3 is the directed telescopic structural representation described in this utility model.
Fig. 4 is that sacculus described in this utility model is to preestablishing the expansible working state schematic representation of direction.
The specific embodiment
Referring to Fig. 2, shown in Figure 3; The described vertebral body directed expansion of this utility model foley's tube; Comprise: conduit 3, an end of conduit 3 is connected with Y-connection 2, and the other end of conduit 3 is connected with sacculus 5; Probe 1 extend in the sacculus 5 after passing joint and the conduit 3 on the Y-connection 2, and the head of probe 1 is provided with radiographic marker 4; Outside conduit 3, also be set with directed sleeve pipe 6, the head of directed sleeve pipe 6 is provided with the directed catch 7 of protrusion forward, and directed catch 7 is positioned at sacculus 5 outsides; Afterbody at directed sleeve pipe 6 is provided with handle 8, be provided with in the handle 8 with directed sleeve pipe 6 in the through hole 9 that communicates of passage.
The method for using of the described vertebral body expansion of balloon catheter of this utility model is: in operation; Directed sleeve pipe 6 is stretched in the anterior vertebral through the passage that gets out in advance; The direction that needs pressurization through the X-ray observation; Regulate the position of the directed catch 7 of directed sleeve pipe 6 heads through handle 8, the fracture site that directed catch 7 can not be strutted blocks, the sacculus on the conduit 35 is extend into the fracture site that needs distraction reduction from directed sleeve pipe 6 after; Through 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 will subside is progressively propped up until returning to clinical treatment requirement, and forms the cavity that can supply fill so that insert bone fillers such as bone cement; Thereby can not increase the weight of the fracture and injury degree at broken position, and avoid causing refracture.
