Description
Technical field
This utility model relates to the vertebra inner fixing device, is specifically related to the clinical threaded fusion cage that the spinal vertebral pathological changes is used that is used to treat.
Background technology
The spinal vertebral pathological changes mainly comprises diseases such as cervical vertebra, the regression of breast intervertebral disc of lumbar vertebra, lumbar vertebra pseudarthrosis, spondylolishesis.The above-mentioned disease of treatment mainly adopts decompression and fusion at present, often need adopt a kind of implanted therapy equipment---threaded fusion cage in this method, substitutes lesion portion and and spinal fusion with threaded fusion cage.Threaded fusion cage struts vertebral body through its external structure, so that recover physiologic radian and height.The structure of at present used threaded fusion cage is: the fusion device body, and the head of fusion device body is the arc of evagination, and the upper and lower surface of fusion device body is respectively arranged with anti-slop serrations, is horizontally arranged with through hole in the fusion device body.Wherein, the anti-slop serrations on the upper and lower surface of fusion device body is used for and is positioned at the upper and lower vertebral body of fusion device distinguishing interlock.The threaded fusion cage height of said structure is fixed; And the intervertebral height of human body can vary with each individual; The doctor can't be fit to different patients' different intervertebral heights through the height of regulating threaded fusion cage in operation; Thereby can't make threaded fusion cage adapt to the intervertebral height and the physiologic radian of human body fully, influence therapeutic effect.
The utility model content
Thereby providing of the problem that this utility model need solve a kind ofly can be regulated the expanding type vertebral body fusion device that oneself height can adapt to different intervertebral heights.
For addressing the above problem, this utility model is realized through following technical scheme.
The expanding type vertebral body fusion device comprises the fusion device body, and fusion device body head is the arc of evagination; The upper and lower surface of fusion device body is respectively arranged with anti-slop serrations, is provided with through hole in the fusion device body vertically, and described fusion device body head is provided with notch; Notch is divided into two lobes with fusion device body head, is provided with the support mechanism that can notch be strutted in the described through hole, and the structure of described support mechanism is: bracer; Bracer is provided with conical nose, and conical nose matches with tapered section on the through hole, and described tapered section directly communicates with notch; The bottom of bracer is connected with the vertebra nail, and described vertebra nail is connected through the inwall of screw thread and through hole, and the bottom of fusion device body is provided with adjustment hole; Can vertebra nail inwardly be screwed into or outwards back-out along through-hole wall through adjustment hole; Vertebra nail promotion bracer makes conical nose strut notch when inwardly being screwed into, and when outwards back-outing, vertebra nail pulling bracer makes conical nose withdraw from notch.
Further; Aforesaid expanding type vertebral body fusion device, wherein, the concrete syndeton of described bracer and vertebra nail is: be provided with cavity in the bracer; The head of vertebra nail extend in the cavity; The head of vertebra nail is provided with draw-in groove, and the bottom interior wall of cavity is provided with fixture block, and described fixture block is stuck in the draw-in groove.
The utility model has the advantages that: owing to be provided with the support mechanism that can notch be strutted; When undergoing surgery; The doctor can strut the appropriate location with notch according to the different intervertebral height of patient; Adjust the height of expanding type vertebral body fusion device, thereby reached the intervertebral height that satisfies human body fully and the requirement of physiologic radian.
Description of drawings
Fig. 1 is the structural representation of the described expanding type vertebral body fusion device of this utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment this utility model is done further to specify.
As shown in Figure 1, the expanding type vertebral body fusion device comprises fusion device body 1; Fusion device body head 4 is the arc of evagination, and the upper and lower surface of fusion device body 1 is respectively arranged with anti-slop serrations 2, is provided with through hole 3 in the fusion device body 1 vertically; Said fusion device body head 4 is provided with notch 41, and notch 41 is divided into two lobes with fusion device body head 4, is provided with the support mechanism that can notch 41 be strutted in the described through hole 3; The structure of described support mechanism is: bracer 5, and bracer 5 is provided with conical nose 51, and conical nose 51 matches with tapered section 31 in the through hole 3; Described tapered section 31 directly communicates with notch 41; The bottom of bracer 5 is connected with vertebra nail 6, and described vertebra nail 6 inwalls through screw thread and through hole 3 are connected, and the bottom of fusion device body 1 is provided with adjustment hole 7; Can vertebra be followed closely 6 through adjustment hole 7 inwardly is screwed into or outwards back-outs along through hole 3 inwalls; Vertebra nail 6 promotion bracers 5 make conical nose 51 strut notch 41 when inwardly being screwed into, and when outwards back-outing, vertebra nail 6 pulling bracers 5 make conical nose 51 withdraw from notch 41.Described bracer 5 with the concrete syndeton of vertebra nail 6 is: be provided with cavity 52 in the bracer 5; The head of vertebra nail 6 extend in the cavity 52; The head of vertebra nail 6 is provided with draw-in groove 61, and the bottom interior wall of cavity 52 is provided with fixture block 53, and described fixture block 53 is stuck in the draw-in groove 61.
During operation, between the upper and lower vertebral body that the implantation of expanding type vertebral body fusion device need be strutted, begin to regulate the height of fusion device body 1 then according to intervertebral height.Utilization turns instrument and through adjustment hole 7 vertebra nail 6 inwardly is screwed into along through hole 3 inwalls; Draw-in groove 61 withstands fixture block 53 away from a side of conical nose 51; Bracer 5 is promoted to the direction near notch 41; Conical nose 51 enters into notch 41 and struts notch 41, and the height of fusion device body 1 uprises gradually, when adjusting to suitable height till.The expanding type vertebral body fusion device just can reach the intervertebral height that satisfies human body fully and the requirement of physiologic radian like this.If think that notch 41 supports De Taigao quickly; Can utilize the instrument of turning vertebra nail 6 outwards to be back-outed along through hole 3 inwalls through adjustment hole 7; Draw-in groove 61 tightly blocks fixture block 53 near a side of conical nose 51, and to the direction pulling away from notch 41, conical nose 51 slowly withdraws from notch 41 with bracer 5; The height of fusion device body 1 is step-down gradually, when adjusting to suitable height, gets final product.
The utility model has the advantages that: owing to be provided with the support mechanism that can notch be strutted; When undergoing surgery; The doctor can strut the appropriate location with notch according to the different intervertebral height of patient; Adjust the height of expanding type vertebral body fusion device, thereby reached the intervertebral height that satisfies human body fully and the requirement of physiologic radian.
