Abstract
The utility model discloses a minimally invasive fusion cage for a lumbar vertebra dypass, and is applied in the field of medical instruments. The minimally invasive fusion cage comprises a supporting main body, wherein fusion holes are formed by penetrating the upper end surface and the lower end surface, and/or the left side surface and the right side surface of the supporting main body; the front end of the supporting main body extends forward to form a tip with a shrinking section and a smooth surface, and the rear end of the supporting main body is provided with screw fixed lugs led out of the upper end surface and the lower end surface of the supporting main body respectively. According to the utility model, in surgery, an appropriate size of the minimally invasive fusion cage can be selected based on the condition of the patient, and then the minimally invasive fusion cage is driven into pathological inter-vertebral space, and is fixed inside a body by screws through the screw fixed ears at the rear end of the supporting main body. By the adoption of the screw fixed ears that can be used for connecting the screws on the supporting main body, an anti-rotating mechanical property of the supporting main body inside the inter-vertebral space is improved, and nail sticks or nail plates that can increase financial burden and operative wound for patients are prevented from being used.
Description
Technical field
This utility model is for medical instruments field, particularly relates to a kind of lumbar vertebra dypass Wicresoft fusion device.
Background technology
Prolapse of lumbar intervertebral disc, lumbar vertebra unstability, the diseases such as lumbar spondylolisthesis usually cause serious lumbago, needs of patients is accepted Lumbar Fusion operative treatment.Conventional Lumbar Fusion modus operandi be take open surgery as main at present, different according to operative approach, comprises posterior lumbar internal fixation art, intervertebral spinal fusion lumbar vertebra posterior-path fusion art, anterior lumbar spinal fusing art etc.Open surgery needs large operative incision, and the soft tissues such as muscle are peeled off on a large scale, and operation wound is large, and postoperative patient recovery process is long, and operative effect is affected.In recent years, rapidly, along with the extensive use at spinal surgery of the development of operating theater instruments and endoscopic technique, the minimally invasive spine fusion of various little otch continues to bring out for less invasive techniques development.Wherein, Wicresoft's fusion of lumbar vertebra dypass is one of more welcome art formula in recent years.The small operative incision of this utilization lumbar vertebra side, is placed on the operation pipeline of Wicresoft the intervertebral space of pathological changes.Then under endoscope or operating loupe auxiliary, by special-purpose operating theater instruments, process the intervertebral disc of pathological changes, complete fusion device inserting and fixing.It is little that operation has otch, and wound is little, goes out insufficiency of blood, the advantage that surgery recovery is fast, thereby be subject to vast spinal surgery doctor's favor and patient's welcome.
But in operation practice, find, to the serious unstable patient of some lumbar vertebras, only insert fusion device, its anti-rotational force is learned poor-performing, usually needs to coordinate the nail rod of dypass or nail-plate to use.Increased so on the one hand patient's financial burden, in the little otch of dypass, inserting nail rod or steel plate also can increase some operation wounds simultaneously.
Utility model content
For addressing the above problem, this utility model provides a kind of anti-rotational force to learn the good lumbar vertebra dypass Wicresoft fusion device of performance.
This utility model solves the technical scheme that its technical problem adopts: a kind of lumbar vertebra dypass Wicresoft fusion device, comprise supportive body, upper and lower end face and/or left and right side through supportive body are provided with fusion hole, the front end of supportive body extends forward and Formation cross-section shrinks gradually, ganoid tip, and the rear end of supportive body is provided with fixedly ear of the screw of being drawn by upper surface and lower surface respectively.
Be further used as the improvement of technical solutions of the utility model, the upper and lower end face of supportive body is equipped with dentation.
Be further used as the improvement of technical solutions of the utility model, the rear end face of supportive body is provided with tool slot.
Be further used as the improvement of technical solutions of the utility model, in tool slot, be provided with and the screwed hole that merges hole conducting.
Be further used as the improvement of technical solutions of the utility model, the cross section of supportive body is rectangular.
The beneficial effects of the utility model: this lumbar vertebra dypass Wicresoft fusion device is in operation, according to patient's condition, select suitable size, then squeeze into pathological interspinal gap, and use fixedly ear of screw that screw passes through supportive body rear end, complete fixing in body, this utility model by supportive body, add can attachment screw the fixing ear of screw, increase the anti-rotational force of supportive body in intervertebral space and learn performance, avoid following closely the use of rod or nail-plate, thereby increase patient's financial burden and operation wound.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is this utility model embodiment overall structure schematic diagram;
Fig. 2 is this utility model example structure front view;
Fig. 3 is this utility model example structure top view.
The specific embodiment
With reference to Fig. 1～Fig. 3, this utility model provides a kind of lumbar vertebra dypass Wicresoft fusion device, comprise supportive body 1, upper and lower end face and/or left and right side through supportive body 1 are provided with fusion hole 10, the front end of supportive body 1 extends forward and Formation cross-section shrinks gradually, ganoid most advanced and sophisticated 11, the rear end of supportive body 1 is provided with fixedly ear 12 of the screw of being drawn by upper surface and lower surface respectively.
In this lumbar vertebra dypass Wicresoft fusion device, screw fixedly ear 12 is provided with two altogether, screw fixedly ear 12 is provided with screw hole 13, in operation, according to patient's condition, select the fusion device of suitable dimension size, then squeeze into pathological interspinal gap, and use fixedly ear 12 of screw that screw passes through supportive body 1 rear end, complete fixing in body, this utility model by supportive body 1, add can attachment screw the fixing ear 12 of screw, increase the anti-rotational force of supportive body 1 in intervertebral space and learn performance, avoid following closely the use of rod or nail-plate, thereby increase patient's financial burden and operation wound.In addition, the fusion hole 10 arranging on supportive body 1, can improve fusion efficiencies on the one hand, guarantees that on the other hand structural strength alleviates integrally-built weight simultaneously.Most advanced and sophisticated 11 design can reduce the resistance that fusion device is implanted diaphysis, and has reduced neural damage probability.
As this utility model preferred embodiment, the upper and lower end face of supportive body 1 is equipped with dentation 14, and the design of dentation 14 can strengthen the stability that supportive body 1 engages with diaphysis.
As this utility model preferred embodiment, the rear end face of supportive body 1 is provided with tool slot 15, is provided with and the screwed hole 16 that merges hole 10 conductings in tool slot 15.Tool slot 15 and screwed hole 16 arrange convenient when fusion device is inserted with insert coordinating of aid.
As this utility model preferred embodiment, the cross section of supportive body 1 is rectangular.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to this utility model spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
