Abstract
The utility model discloses a kind of medicine carrying spinal column Invasive lumbar fusion device, belong to orthopedic fixation device tool technical field, comprise fusion device body, it is characterized in that fusion device body is provided with drug storage tank, drug storage tank lid is covered by filter screen, the both sides of drug storage tank are provided with reciprocal latch structure, be placed with infection or facilitate bone medicine in described drug storage tank.This utility model structure is simple, reasonable in design, not only on fusion device, be provided with reciprocal latch structure, fusion device is implanted after intervertebral space can fixedly secure, and be provided with drug storage tank at fusion device body, after implanting, medicine can slow releasing, efficiency prevention infection, prevent the generation of the post-operative complication such as pseudarthrosis, promote the early stage fusion of vertebral body, there is good Clinical practice effect.
Description
Technical field
This utility model relates to medical equipment, is specifically related to a kind of medicine carrying spinal column Invasive lumbar fusion device.
Background technology
Spinal column degeneration is clinical modal spinal surgery disease, has a strong impact on minimal invasive treatment and work, once medicine and physics expectant treatment invalid, operative treatment is finally selected often.Modus operandi is developed to current modal interbody fusion by simple lumbar discectomy, and occurs a series of fusion formula in perfect fusion between pursuit vertebral body, as intertransverse process autograft fusion art, and Minor articulus bone graft fusion, vertebral plate bone graft fusion etc.But from dissection and angle of physiology, Intervertebral fusion art not only can remove the shakiness that lumbar vertebra bends and stretches direction, also can remove simultaneously and bend and stretch the unstable side direction shakiness produced in direction and rotate shakiness, and the disc tissue of pain may be caused to be excised.Be applied to waist interbody fusion treatment discogenic pain since obtaining success, various Invasive lumbar fusion device is come out one after another from Invasive lumbar fusion device, and be subject to clinically widely accepting.
The fusion device used clinically is at present divided into metal Invasive lumbar fusion device, macromolecule Invasive lumbar fusion device, composite Invasive lumbar fusion device.In spinal surgical procedure, strike off the intervertebral disc of regression, under the help of dilator, fusion device is implanted intervertebral space, realize interpyramidal fusion by the growth of osseous tissue.But due to these material shortage bone conduction and self-bone grafting ability, easily bring out infection after implanting as foreign body simultaneously, often cause pseudoarticulation formation, bring out infection etc., cause operative failure.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, proposes a kind of medicine carrying spinal column Invasive lumbar fusion device, by the slow releasing of medicine, realizes the early stage rapid fusion of vertebral body.
To achieve these goals, the technical solution adopted in the utility model is.
A kind of medicine carrying spinal column Invasive lumbar fusion device, belong to orthopedic fixation device tool technical field, comprise fusion device body, it is characterized in that fusion device body is provided with drug storage tank, drug storage tank lid is covered by filter screen, the both sides of drug storage tank are provided with reciprocal latch structure, be placed with infection or facilitate bone medicine in described drug storage tank.
Particularly, described drug storage tank is arranged on the contact surface of both sides terminal plate of vertebral body.
Particularly, the screen material of described drug storage tank lid is not limited to consistent with fusion device bulk material.
In operation process, take out the intervertebral disc of pathological interspinal gap, by the soleplate scraped clean of upper hypocentrum, implant fusion device, depress at the card of drug storage tank both sides reciprocal latch structure, fusion device body is rigidly mounted in intervertebral space, anti-infectives in drug storage tank or skeletonization medicine slowly release by the filter screen of medicine groove lid, reach prevention infection, promote the effect of vertebral fusion, the vertebral body of pathological changes is merged in early days, thus makes patient obtain rehabilitation in early days.
By technique scheme, the beneficial effects of the utility model are:
This utility model structure is simple, reasonable in design, fixation, and owing to being provided with drug storage tank at fusion device body, after fusion device implants, medicine can slow releasing, can effective prevention of postoperative infection, and promotion vertebral fusion, reaches the object of rapid healing patient.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In figure 1, fusion device body; 2, drug storage tank; 3, reciprocal latch structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
As shown in drawings, a kind of medicine carrying spinal column Invasive lumbar fusion device, belong to orthopedic fixation device tool technical field, comprise fusion device body, it is characterized in that fusion device body is provided with drug storage tank, drug storage tank lid is covered by filter screen, and the both sides of drug storage tank are provided with reciprocal latch structure, is placed with infection or facilitates bone medicine in described drug storage tank.
In operation process, take out the intervertebral disc of pathological interspinal gap, by the soleplate scraped clean of upper hypocentrum, implant fusion device, depress at the card of drug storage tank both sides reciprocal latch structure, fusion device body is rigidly mounted in intervertebral space, anti-infectives in drug storage tank or skeletonization medicine slowly release by the filter screen of medicine groove lid, reach prevention infection, promote the effect of vertebral fusion, the vertebral body of pathological changes is merged in early days, thus makes patient obtain rehabilitation in early days.
