Abstract
The utility model provides an it fuses ware to move back cervical vertebra from preventing, belongs to medical instrument technical field. Including fusing the ware main part, fuse the column body that the ware main part be the hollow human anatomy of an according with shape, all be equipped with anti -skidding tooth biplanar from top to bottom, its characterized in that, it still includes rotating barriers and connecting pin, and rotating barriers is connected to install by the connecting pin and is fusing ware main part terminal surface portion, and rotating barriers can be around the connecting pin rotation, rotating barriers's peripheral system have the blade, the rotating barriers both ends are equipped with waist type hole. The utility model discloses install rotating barriers and fusing ware terminal surface portion, both remain and fused the ware structural integrity, can realize preventing moving back the function again, and the complication that can prevent the postoperative takes place, operation time is short, surgical cost is low.
Description
Technical field
This utility model belongs to technical field of medical instruments, and it is a kind of from anti-back cervical vertebral fusion cage for being specifically related to.
Background technology
Intervertebral disc protrusion of cervical vertebra disease is spinal surgery commonly encountered diseases, being carry out cervical operation at present, namely in order to recover the physiologic radian of intervertebral height and cervical vertebra, making cervical vertebra reach at once stable for the effective Therapeutic Method of prolapse of cervical intervertebral disc.Interbody fusion is generally used for the diseases such as treatment spinal column regression and shakiness, can recover intervertebral height, expand intervertebral foramina, support front pillar and increase Fusion levels stability.Late 1970s starts the research of Invasive lumbar fusion device, after be used to treatment lumbar degenerative and change and the disease such as lumbar instability, in Cervical Fusion, obtained significant progress again afterwards.This Therapeutic Method not only can recover the physiology height of intervertebral, maintains normal physiological camber, simultaneously when anterior spinal column stressed maximum strengthen the support of front pillar, make the sections merged obtain enough stability.
Traditional cervical fusion surgery is generally that fusion device coordinates anterior plate fixation to use simultaneously, anterior plate fixation can effectively prevent cervical vertebral fusion cage from skidding off in this case, but this with the use of mode also can only prevent skidding off forward of cervical vertebral fusion cage, fusion device coordinates steel plate to use simultaneously, operating time is long, and surgery cost is also more expensive.Cervical steel plate Post operation has a series of complication and occurs, such as trunnion flaccidity, dysphagia etc.Also there is a collection of fusion device for solving the problem in recent years, as notification number: CN202288538U discloses a kind of cervical spine locking fusion device, this fusion device is also that rotating blade is cut in vertebral body again after fusion device implants vertebral body, playing self-locking action, is a kind of effective ways solving clinical problem.But the blade of this invention is arranged on the middle front part of fusion device, and the length of blade can be limited by the width of fusion device, not can be good at playing fixation.Simultaneously in order to enable blade rotate, fusion device middle front part can be slotted, and can affect the intensity of fusion device main body like this.Notification number: CN:204106172U patent, disclose a kind of cervical vertebra locking fusion device, this fusion device is also that a kind of fusion device adds steel plate operation in fact, and inventor is combined togather, facilitate operation technique, but fundamentally can not solve some postoperative latter problem.Also have notification number 201701334U cervical vertebral fusion cage, although there is its feature, there is no the technical scheme of anti-cervical vertebral fusion cage from anti-back.So development is a kind of existing from anti-back function, can eliminate again postoperative complication and occur, and operating time is short, the cervical vertebral fusion cage that surgery cost is low is very necessary.
Summary of the invention
The purpose of this utility model is in order to overcome the disadvantage of prior art, and provide a kind of from anti-back cervical vertebral fusion cage, butterfly is arranged on fusion device end face portion by it, has both retained fusion device structural integrity, can realize anti-back function again; And can prevent postoperative complication from occurring; Operating time is short; Surgery cost is low.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of from anti-back cervical vertebral fusion cage, comprise fusion device main body, fusion device main body is the column meeting human dissection shape of a hollow, upper and lower two faces are equipped with anti-slop serrations, and its main points are, it also comprises butterfly and connecting pin, butterfly is mounted on fusion device bulk end face by connecting pin, and butterfly can rotate around connecting pin; The periphery of described butterfly is shaped with cutting edge, convenient after fusion device main body implant into body, is cut in vertebral body by external force around connecting pin rotation, makes itself and vertebral body reach stable and effectively merges; Butterfly two ends are provided with waist-shaped hole, merge fixing for fusion device main body in vertebral body to screw in screw in waist-shaped hole.
As preferably, described connecting pin is provided with internal thread hole.
This utility model compared with prior art has following beneficial effect: because the periphery of butterfly is shaped with cutting edge, can be embedded in the shallow wall of vertebral body, itself and vertebral body are reached and more stablizes effective fusion by external force around connecting pin rotation; Butterfly two ends are provided with waist-shaped hole, merge fixing for fusion device main body in vertebral body to screw in screw in waist-shaped hole.Said structure had both remained the integrity of fusion device structure, can realize anti-back function again; Again because it and vertebral body have stable effective fusion, and fusion device comprises fusion device main body, butterfly and connecting pin, and the parts that operation needs are complete, and operation technique is convenient, and operating time is shortened, so can prevent postoperative complication from occurring; Because operating time is short, so surgery cost have also been obtained reduction.

Detailed description of the invention
Embodiment below just represented by Fig. 1-6 is further described this utility model:
Comprise fusion device main body 1, fusion device main body 1 is the column meeting human dissection shape of a hollow, upper and lower two faces are equipped with anti-slop serrations 2, it also comprises butterfly 3 and connecting pin 4, butterfly 3 is mounted on fusion device main body 1 end face portion by pin-and-hole 8 by connecting pin 4, and butterfly 3 can rotate around connecting pin 4; The periphery of described butterfly 3 is shaped with cutting edge 5, convenient after fusion device main body 1 implant into body, to be rotated cut in the shallow wall of vertebral body by external force around connecting pin 4, itself and vertebral body is reached stablize effectively to merge; Butterfly 3 two ends are provided with waist-shaped hole 6, merge fixing for fusion device main body 1 in vertebral body to screw in screw 9 in waist-shaped hole; Described connecting pin 4 is provided with internal thread hole 7, and it can coordinate fusion device implantation device to use.
The concrete operations of the present embodiment in operation are as follows, doctor by the disc removal of surgical operation by pathological changes, after excision to upper hypocentrum carry out process be polished to lamina surface hemorrhage till.Carry out a series of strut and measure after, the internal thread hole 7 implantation device being connected to connecting pin 4 implants the present embodiment, until fusion device main body 1 is absorbed in the certain distance of intervertebral disc, now rotate butterfly 3 by external device, make it cut in hypocentrum, then in two waist-shaped holes 6, screw in screw 9 by outer sighting device and fix and can complete operation.
