Description

一种叠加式全高度椎体成形器 A type of overlay is full-height vertebroplasty

技术领域 FIELD

[0001] 本发明涉及一种椎体成形器,尤其涉及一种叠加式全高度椎体成形器。 [0001] The present invention relates to a vertebroplasty, and more particularly, to a stack-full-height device vertebroplasty.

背景技术 Background technique

[0002] 椎体成形术是一种新的脊柱微创手术,目前主要用于治疗椎体侵袭性血管瘤,骨质疏松症椎体压缩形骨折、椎体原发或转移性肿瘤等疾患治疗,可分为骨水泥和非骨水泥注入两类,前者包括经皮椎体成形术(percutaneous vertebroplasty,PVP)和脊柱后凸成形术(percutaneous kyphoplasty,PKP)两种;后者有椎体支柱块、镍钛记忆合金椎体成形器等。 [0002] Vertebroplasty is a new minimally invasive spine surgery, mainly for the treatment of invasive vertebral hemangiomas, osteoporosis vertebral compression fractures, vertebral disorder treating primary or metastatic tumor etc. can be divided into non-cemented and cementless implantation categories, the former including percutaneous vertebroplasty (percutaneous vertebroplasty, PVP) and kyphoplasty (percutaneous kyphoplasty, PKP) two kinds; the latter vertebral strut block , nitinol or the like vertebroplasty. 它们有其各自的特点,如PVP是在高压力的条件下向无空间的椎体内注射骨水泥;PKP是通过骨扩张器在椎体内扩张产生空腔,低压力下向椎体空腔内注射骨水泥,渗漏较局限,其安全性较PVP大大提高等,但不论骨水泥和非骨水泥注入类椎体成形器,受形变原理等因素的限制,均只能部分恢复椎体压缩所丧失的高度,不利于脊柱后凸畸形的恢复。 They have their own characteristics, such as PVP is no space into the vertebral bone cement injected under high pressure; PKP is generated by a bone dilator cavity, at low pressure cavity within the vertebral body to vertebral injection of bone cement leakage than its predecessor, its security is greatly improved compared with PVP, etc., but regardless of cemented and uncemented implantation class vertebroplasty, a limited factor of deformation principle, are only partially restore vertebral compression the loss of height, kyphosis of the spine is not conducive to recovery.

[0003] 有鉴于此,亟待针对上述技术问题,另辟蹊径设计一种全高度椎体成形器,以完全纠正椎体压缩所丧失的高度,恢复椎体外形及脊柱生理曲度。 [0003] In view of this, for the above-described urgent technical problems, another way to design a full height of vertebroplasty is to completely correct the loss of vertebral height compression, restoration of spinal curvature and shape the vertebral body.

具体实施方式 Detailed ways

[0020] 如图1~3所示的叠加式全高度椎体11成形器,包括有叠加植入部组件,所述叠加植入部组件上连接有器械部组件,其与众不同之处在于:本发明所采用的叠加植入部组件包括有叠加片组件。 [0020] FIG 11 vertebrae superimposed full-height shaper of 1 to 3, comprising superimposing the implant assembly, said superposed assembly is connected to the implant device assembly, which distinguishes that : superimposing implant assembly used in the present invention comprises a sheet overlay assembly. 同时,器械部组件包括有内固定杆3,在叠加片组件上连接有内固定杆3。 Meanwhile, the instrument assembly comprises a fixed rod 3, rod 3 is connected to the fixed plate assembly superimposed. 具体来说,内固定杆3外部设置有外导管4,在外导管4前段设置有把持组件5,把持组件5与叠加片组件相接触。 Specifically, the external fixed rod 3 is provided with an outer duct 4, the outer catheter 4 is provided with a pre-stage assembly 5 gripping, the gripping assembly 5 is in contact with the overlay sheet assembly. 并且,外导管4中段外围设置有导向固定管6,导向固定管6 上连接有调节组件,在外导管4尾段设置有分离组件。 Further, the outer periphery of the middle conduit 4 is provided with a stationary guide tube 6, fixed to the guide tube 6 is connected to the adjustment assembly, the outer end section 4 is provided with a duct separation assembly. 考虑到使用的便捷程度,导向固定管6及调节组件可容外导管4通过并能调控外导管4进入椎体11深度。 Considering the degree of easy use, the guide tube 6 is fixed and the adjustment assembly can accommodate an outer conduit 4 and through the outer duct 4 can regulate the depth 11 into the vertebral body.

[0021] 就本发明一较佳的实施方式来看,为了便于使用,叠加片组件包括有上叠加片1 和下叠加片2,在上叠加片1和下叠加片2上均设置有凹槽。 [0021] For a preferred embodiment of the present invention, the point of view, for ease of use, there is superposed on the superposed sheet assembly comprising a sheet and a lower sheet 2 superposed on the superposed sheets 1 and 2 superposed sheets are provided with recesses . 由此,上叠加片1和下叠加片2对合组装时,凹槽合并为衔接槽。 Accordingly, the superimposed overlay sheet and a lower sheet 1 when assembled together, the grooves merge two pairs of engagement grooves. 与之对应的是,持组件上设置有衔接头10,衔接槽与衔接头10相接触。 Corresponding thereto is provided with a holding component on the adapter 10, the adapter 10 with the engagement groove contact.

[0022] 进一步来看,为了便于使用调节,采用的调节组件包括有调节套12,调节套12活动设置在导向固定管6外围,在调节套12上连接有锁紧套13。 [0022] Further view, adjusted for ease of use, using adjustment assembly comprises an adjustment sleeve 12, the adjustment sleeve 12 is movably disposed in the guide tube 6 is fixed peripheral, connected to the adjustment sleeve 13 on the locking sleeve 12. 当然,为了操控便利,定位准确,调节套12与锁紧套13内壁设置有螺纹,在导向固定管6外壁设置有螺纹,由此,调节套12、锁紧套13与导向固定管6螺纹连接。 Of course, in order to facilitate handling, accurate positioning, adjusting sleeve 12 and the inner wall 13 is provided with a threaded locking sleeve, the outer wall of the guide tube 6 is provided with a fixing screw, whereby the adjusting sleeve 12, locking sleeve 13 is fixed to the guide tube 6 screwed . 这样,调节套12可与导向固定管6连接并调节连接长度,锁紧套13可实现螺纹锁紧。 Thus, the adjustment sleeve 12 with the guide pipe 6 is connected and fixed to adjustable connector length, locking sleeve 13 may be implemented thread lock.

[0023] 再进一步来看,为了便于准确分离,采用的分离组件包括有手柄14,所述的手柄14设置有压紧螺母15,在压紧螺母15通过离合螺母9连接有限位环8。 [0023] Still further point of view, in order to facilitate accurate separation include separation assembly using a handle 14, a handle 14 is provided with the compression nut 15, the compression nut connected via a clutch ring nut 9 15 8 finite bit. 同时,在限位环8 上连接有离合把手7。 Meanwhile, in the stop ring 8 is connected to a clutch handle 7. 当然,为了离合螺母9更有效的工作,在外导管4前段设置有螺纹。 Of course, the clutch nut 9 to work more efficiently, the outer catheter 4 is provided with a threaded front section. 这样,在实际操作时,压紧螺母15可实现手柄14与外导管4前端相连。 Thus, in actual operation, the compression nut 15 may be implemented with an outer handle 14 is connected to the distal end 4 of the catheter. 离合螺母9可通过外导管4前端螺纹顶紧限位环8,限位环8再顶紧离合把手7从而实现上叠加片1和下叠加片2对合。 Clutch nut 9 through the outer ring 8 may be the distal end 4 of the catheter crest tight stop, the stop ring 8 Zaiding clutch handle 7 in order to achieve tight superimposed sheet 1 and the lower two pairs of superposed sheets together. 这样,上叠加片1和下叠加片2与外导管4连成一体以便通过导向固定管6及调节组件进入椎体11内。 Thus, superimposed on the lower sheet 1 and the overlay plate 2 integral with the outer tube 4 to be fixed by the guide tube 6 and the adjustment assembly 11 into the vertebral body. 将离合螺母9反向转动,限位环8松开离合把手7,离合把手7转动90度向后退移,内固定杆3横截面呈矩形通过上叠加片1和下叠加片2对合后内矩形槽从而实现上叠加片1和下叠加片2分离。 The reverse rotation of the clutch nut 9, the stop ring 7 handle 8 released the clutch, the clutch shifter 90 of the handle 7 is rotated backward by the superimposed overlay sheet and a lower sheet 1 after the engagement lever 3 fixed rectangular in cross section two pairs rectangular grooves enabling the superimposed sheets 1 and 2 separated overlay sheet.

[0024] 当然,考虑到实际使用时操作便利,导向固定管6前端呈尖齿状以便切入骨质起固定作用。 [0024] Of course, considering the convenience of operation when actual use, the guide tube 6 is fixed to the distal end of the tip-dentate bone cut from the fixed effect. 同样的,内固定杆3前端横截面为矩形,可以实现更好的使用效果。 Similarly, the rod 3 is fixed to the front end of a rectangular cross section, you can achieve better results.

[0025] 结合本发明的实际使用情况来看,如图3所示,术前在椎体11侧位X线图像或CT 剖面图上,测量椎体11上下终板间的高度b,并依据高度b选择合适规格的上叠加片1和下叠加片2。 [0025] The actual use of the present invention, the view shown in Figure 3, before surgery on the 11 X-ray image or CT sectional view of a lateral vertebral body, the height of the vertebral body end 11 b between the upper and lower plates, and based on select the appropriate size of the height b is superimposed on the lower sheet 1 and sheet 2 superposed. 之后,将组装好的上叠加片1和下叠加片2逐次经椎弓根进入椎体11内,叠加片不断叠加完全实现椎体11高度恢复。 Thereafter, the assembled superimposed sheet 1 and lower plate 2 sequentially superimposed into the vertebral body through the pedicle 11, continuously superimposed overlay sheet 11 vertebral height to achieve full recovery. 由于该叠加式全高度椎体11成形器支撑力稳固,椎体11高度很少下降,可防止术后椎体11高度过多丢失从而保证疗效。 Since the superimposed full-height vertebral solid support force shaper 11, 11 vertebral height decreased very little to prevent excessive loss of height after vertebral body 11 so as to ensure the efficacy.

[0026] 通过上述的文字表述可以看出,采用本发明后,依托于叠加植入部组件与器械部组件可以有效配合脊柱椎体成形术的实施,避免出现术后远期椎体高度丢失。 [0026] As can be seen by the above textual representation, the present invention relies on the embodiment of the instrument assembly superimposing implant assembly can effectively fit the spine vertebroplasty, to avoid long-term postoperative vertebral height loss occurs. 并且,本发明构造合理,操作简便,便于推广使用。 The present invention has reasonable structure, easy to operate, easy to be widely used.
