Description
Technical field
The present invention relates to orthopedic medical device field, referring more particularly in vertebral body operation for setting up the combined probe sleeve of bone cement injection channel.
Background technology
Vertebral body operation, a kind of under C arm machine (i.e. X-ray) is irradiated, utilize less invasive techniques that the biomaterials such as bone cement are injected vertebral body through lamina of vertebral arch, to recover vertebral height, strengthen the comprcssive strength of pathological changes vertebral body, prevent vertebral body from subsiding further and deformity, alleviate patient pain and improve the Therapeutic Method of function.Combined probe sleeve is for one of conventional apparatus in vertebral body operation, its structure is: comprise sleeve and probe with matching, sleeve afterbody is provided with lever, lever is provided with female Luer, female Luer communicates with the passage in sleeve, also be provided with at probe tails and push away handle, end of probe can insert in sleeve through female Luer and move in sleeve, triangle cutting edge is respectively arranged with at the head of probe and sleeve, when probe is inserted into after in sleeve completely, the triangle cutting edge of end of probe and sleeve head can be spliced into a complete triangular edge.
The combined probe sleeve of said structure need use in conjunction with jacketed syringe, during operation, under X-ray irradiates, the lamina of vertebral arch of pathological changes vertebral body trailing edge is punctured by the triangular edge of combined probe sleeve head, sleeve head is brought in pathological changes vertebral body, then use jacketed syringe by the bone cement that modulates by the channel injection in female Luer and sleeve in pathological changes vertebral body, while injection bone cement, can be rotated in a circumferential direction sleeve sleeve is slowly shifted out, when expiring whole cavity when Cement fixation and be solidified as one with pathological changes vertebral body and sleeve head, again sleeve is extracted from the bone cement of pathological changes vertebral body.
The major defect that the combined probe sleeve of said structure form exists is: one, the combined probe sleeve of this structure is only applicable to the sufferer that sclerotin comparatively loosens, if the sclerotin of sufferer is finer and close and intensity is higher, then triangular edge is difficult to puncture pathological changes vertebral body, now by other instruments with regard to needs is knocked in after in pathological changes vertebral body and can carry out subsequent procedures by combined probe sleeve; Two, in subsequent procedures, when expiring whole cavity when Cement fixation and be solidified as one with pathological changes vertebral body and sleeve head, be difficult to sleeve to extract from the bone cement of pathological changes vertebral body, limit is now just needed to press the periphery of corrective surgery position, and shaking moving sleeve simultaneously, the bone cement after making sleeve head and solidifying loosens, and is extracted by sleeve to facilitate from pathological changes vertebral body, this very easily causes bone cement and pathological changes vertebral body in conjunction with insecure, thus have impact on the effect of operation.
Summary of the invention
The technical problem of solution required for the present invention is: provide a kind of sleeve can conveniently to insert in pathological changes vertebral body and from pathological changes vertebral body, easily take out, can not affect the combined probe sleeve of surgical effect.
For solving the problem, the technical solution used in the present invention is: described combined probe sleeve, comprise sleeve and probe with matching, sleeve afterbody is provided with lever, be in one's hands handle tail U-lag in be provided with female Luer, female Luer communicates with the passage in sleeve, probe tails be also provided with can fasten with lever afterbody U-lag push away handle, end of probe can insert in sleeve through female Luer and move in sleeve, triangle cutting edge is respectively arranged with at the head of probe and sleeve, when probe is inserted into after in sleeve completely, the triangle cutting edge of end of probe and sleeve head can be spliced into a complete triangular edge, also thread segment is provided with in sleeve head, also locking mechanism is provided with at the lever of sleeve and pushing away between handle of probe, locking mechanism can by lever and the relative position locking pushing away handle, thus the relative position of probe and sleeve is locked, make can not produce relative motion between the two.
Further, aforesaid combined probe sleeve, wherein, the effective length being arranged on the thread segment of sleeve head is 10 ~ 12 millimeters.
Further, aforesaid combined probe sleeve, wherein, described locking mechanism comprises: be arranged on two bumping posts in lever afterbody U-lag, two bumping posts lay respectively at female Luer both sides, be positioned at before lever on the upside of U-lag and be provided with the first draw-in groove, be positioned at after lever on the downside of U-lag and be provided with the second draw-in groove; Also be provided with two the 3rd draw-in grooves matched with two bumping posts pushing away on handle, two bumping posts all slide onto in the 3rd draw-in groove by the bumping post entering surface in the 3rd draw-in groove, be provided with first boss that can fasten with the first draw-in groove pushing away above handle, be provided with second boss that can fasten with the second draw-in groove pushing away below handle; In work, probe to be inserted in sleeve and make to push away handle and rotate some angles relative to lever, thus insert in the process of sleeve at probe, push away handle and lever can not be interfered each other, after probe inserts sleeve completely, and then rotate and push away handle, two bumping posts are made to move in the 3rd respective draw-in groove, first, second boss snaps in first, second draw-in groove respectively simultaneously, will push away the relative position locking of handle and lever, thus the relative position of locking probe and sleeve.
Further, aforesaid combined probe sleeve, wherein, bumping post entering surface in 3rd draw-in groove be from outer end gradually inwardly tilt inclined-plane, also fin is provided with in the 3rd draw-in groove, bumping post can move to fin by bumping post entering surface and cross fin under the effect of external force, and fin has the effect of bumping post gear in the 3rd draw-in groove.
The invention has the beneficial effects as follows: adopt the combined probe sleeve of said structure, by the relative position locking of locking device by probe and sleeve, the head of probe and sleeve is formed and maintains a complete triangular edge not loosen; In the mode that probe and sleeve head adopt triangular edge to combine with screw thread, no matter the pathological changes vertebral body sclerotin of patient comparatively to loosen or finer and close, all the head of combined probe sleeve is screwed in pathological changes vertebral body reposefully, for subsequent procedures lays the foundation by the tip of triangular edge and the effect that screws of screw thread; In subsequent procedures, when expiring whole cavity when Cement fixation and be solidified as one with pathological changes vertebral body and sleeve head, turnbarrel in the other direction is only needed easily to be shifted out from pathological changes vertebral body by sleeve, neither need to use brute-force to extract sleeve, also the fastness that the bone cement be filled in pathological changes vertebral body combines with pathological changes vertebral body can not be destroyed, simple to operate, safe and reliable, good operation effect.
