Abstract
The utility model discloses a bone cement pushing-injection device applied to balloon kyphoplasty. The bone cement pushing-injection device comprises a probe sleeve, wherein a grab handle is arranged at the tail end of the probe sleeve; a toothed cutting edge is formed at the front end of the probe sleeve and is communicated with a channel in the probe sleeve; a Luer adapter is arranged on the grab handle; the interface of the Luer adapter is communicated with the channel in the probe sleeve; an injection outlet is formed in one side, near the toothed cutting edge, of the probe sleeve; the injection outlet is communicated with the channel in the probe sleeve. According to the bone cement pushing-injection device with the structure, bone cement can be injected towards an expanding reset position, and the sound side of a lesion centrum is basically not affected by an injection force, so that the fracture degree of the lesion centrum is not increased and the operation effect is good.
Description
Technical field
This utility model relates to orthopedic medical device field, refers more particularly to the bone cement infusing device using in vertebral body balloon expandable plasty.
Background technology
Vertebral body balloon expandable plasty is a minimally invasive spine surgical operation, be mainly used in the treatment of compression fracture of vertabral body, compression fracture of vertabral body is the modal complication of sufferers of osteoporosis face, can cause local pain, moving obstacle, and serious also can cause lower extremity paralysis.First vertebral body balloon expandable plasty expands to recover the height of disease damage vertebral body by sacculus, and inject the implants such as bone cement in backward pathological changes vertebral body, fill, thereby strengthen the strength and stability of pathological changes vertebral body, make the not compressed distortion again of vertebral body after restoring.
Bone cement infusing device is one of apparatus that treatment compression fracture of vertabral body is conventional, be mainly used in that bone cement is injected to disease damage vertebral body inner, on market, the structure of existing bone cement infusing device is: comprise probe sleeve, at probe sleeve tail end, be provided with lever, on lever, be provided with the hole communicating with passage in probe sleeve, the front end of probe sleeve is provided with toothed cutting edge, and toothed cutting edge communicates with the passage in probe sleeve.
The bone cement infusing device of said structure need be used in conjunction with in conjunction with foley's tube, in operation, foley's tube is stretched in pathological changes vertebral body by the service aisle of setting up in advance, by the expansion of sacculus, prop up the vertebral body of subsiding until pathological changes vertebral body returns to the original form, then remove sacculus, the probe sleeve of bone cement infusing device is stretched in foley's tube, and inject the bone cement modulating in probe sleeve, bone cement is filled in the cavity of vertebral body, fill complete, probe sleeve is exited to foley's tube, finally foley's tube is shifted out external.
The major defect that the bone cement infusing device of said structure form exists is: bone cement inevitably can exist nondirectional factor while filling, when pathological changes vertebral body is one-sided subsiding; that side that the intact nothing of pathological changes vertebral body is subsided more or less can be subject to certain pressure; cause that side direction outside projection that pathological changes vertebral body is intact; increase the weight of so most probably the fracture degree of pathological changes vertebral body; not only do not reach the surgical effect of expection, may increase the weight of on the contrary the pain of sufferer.
Utility model content
The technical problem of the required solution of this utility model is: a kind of bone cement infusing device that can make bone cement fill to predefined distraction reduction direction is provided.
For addressing the above problem, the technical solution adopted in the utility model is: described bone cement infusing device, comprise probe sleeve, at probe sleeve tail end, be provided with lever, the front end of probe sleeve is provided with toothed cutting edge, toothed cutting edge communicates with the passage in probe sleeve, on lever, be provided with female Luer, the interface of female Luer communicates with the passage in probe sleeve, and in a side of probe sleeve and the position of close toothed cutting edge, offer injection outlet, injection outlet communicates with the passage in probe sleeve.
The beneficial effects of the utility model are: the bone cement infusing device that uses said structure, during operation, the injection outlet of probe sleeve is filled towards predefined distraction reduction direction, in bone cement injection process; the side group that pathological changes vertebral body is intact originally can not be subject to injection force; thus can not increase the weight of the fracture degree of pathological changes vertebral body, the directed filling of bone cement makes bone cement filling more even, and surgical effect is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of bone cement infusing device described in the utility model.
Fig. 2 is the plan structure complete section schematic diagram in Fig. 1.
Fig. 3 is the partial enlarged drawing of A part in Fig. 2.
Fig. 4 is the working state schematic representation that bone cement infusing device described in the utility model is filled to predetermined direction.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, technical scheme described in the utility model is described in further detail.
Bone cement infusing device described in Fig. 3 as shown in Figure 1, Figure 2,, comprise probe sleeve 1, at probe sleeve 1 tail end, be provided with lever 11, the front end of probe sleeve 1 is provided with toothed cutting edge 4, toothed cutting edge 4 communicates with the passage in probe sleeve 1, is provided with female Luer 2 on lever 11, and the interface of female Luer 2 communicates with the passage in probe sleeve 1, in a side of probe sleeve 1 and the position of close toothed cutting edge 4, offer injection outlet 3, injection outlet 3 communicates with the passage in probe sleeve 1.
Bone cement infusing device described in the utility model need to be used in conjunction with directed foley's tube 5 and jacketed syringe, and directed foley's tube 5 and jacketed syringe can directly be purchased and arrive on market.As shown in Figure 4, when operation, open X ray, directed foley's tube 5 is stretched in pathological changes vertebral body by the service aisle of setting up in advance, the opening part of directed foley's tube 5 is towards the direction of subsiding of pathological changes vertebral body, by the expansion of sacculus, prop up the vertebral body of subsiding until pathological changes vertebral body returns to the original form, then remove sacculus, the probe sleeve 1 of bone cement infusing device is stretched in directed foley's tube 5, injection outlet 3 directions of subsiding towards pathological changes vertebral body of probe sleeve 1, and the toothed cutting edge 4 of probe sleeve 1 front end is against on vertebral body, vertebral body blocks the outlet of toothed cutting edge 4, then use jacketed syringe that the bone cement modulating is injected in the passage in probe sleeve 1 by female Luer 2, now, bone cement is only expelled in the side of cavity 6 of vertebral body from injection outlet 3, when the side of cavity 6 is filled completely, when injecting bone cement, probe sleeve 1 is slowly shifted out, now, bone cement is injected to cavity 6 from the exit of the toothed cutting edge 4 of probe sleeve 1 front end, until bone cement is filled full whole cavity 6, then probe sleeve 1 is shifted out from directed foley's tube 5, finally directed foley's tube 5 is shifted out external.Use the bone cement infusing device of said structure, in bone cement injection process, the side group that pathological changes vertebral body is intact originally can not be subject to injection force, thereby can not increase the weight of the fracture degree of pathological changes vertebral body, the directed filling of bone cement makes bone cement filling more even, and surgical effect is better.
