With simple structure and convenient use, the utility model can not only remove prolapsed lumbar intervertebral disc once for all but also efficiently protect the nerve root and endorachis, thereby saving the operation time, reducing the operation risks, and being extensively applicable to lumbar intervertebral disc extraction operations in hospitals.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly a kind of lumbar intervertebral disc extractor that is used to cut the lumbar intervertebral disc of deviating from.
Background technology
At present, being used to cut lumbar intervertebral disc in the hospital and deviating from, generally is the way that adopts the way of escape to window, manifest the lumbar intervertebral disc deviate from after, adopt knife blade to cut posterior longitudinal ligament and fibrous ring, take out the disc tissue of deviating from then.Long, hemorrhage many owing to operating time like this, for the patient has increased misery, and might injured nerve root and spinal dura mater.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy to use, the lumbar intervertebral disc of can disposable excision deviating from, and effectively neuroprotective root and spinal dural lumbar intervertebral disc extractor.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of lumbar intervertebral disc extractor, mainly form by outer sleeve and inner sleeve, it is characterized in that: the top of outer sleeve is connected with handle, the bottom is fixedly connected with bracing frame, the inner sleeve top is fixedly connected with rotation disc, and the bottom is provided with endless knife.
After this utility model lumbar intervertebral disc extractor adopts said structure, 1, the lumbar intervertebral disc can disposable excision deviate from; 2, effectively neuroprotective root and spinal dura mater.
Description of drawings
Below in conjunction with drawings and Examples this utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, rotation disc, 2, inner sleeve, 3, outer sleeve, 4, endless knife, 5, bracing frame, 6, handle.
The specific embodiment
As can be seen from Figure 1, a kind of lumbar intervertebral disc extractor mainly is made up of outer sleeve 3 and inner sleeve 2, it is characterized in that: the top of outer sleeve 3 is connected with handle 6, the bottom is fixedly connected with bracing frame 5, and inner sleeve 2 tops are fixedly connected with rotation disc 1, and the bottom is provided with endless knife 4.
Referring to Fig. 1, during clinical practice, the conventional lumbar surgery of going ahead of the rest is windowed between vertebral plate, by medical apparatus and instruments such as nerve hooks, manifests outstanding lumbar intervertebral disc.Aiming at outstanding lumbar intervertebral disc is placed on it outer sleeve 3, the bracing frame 5 that outer sleeve 3 bottoms are provided with mainly plays the support fixation effect, grasp handle 6, keep outer sleeve 3 steady, then inner sleeve 2 is enclosed within the outer sleeve 3, the rotation disc 1 at rotation inner sleeve 2 tops, the endless knife 4 that drives inner sleeve 2 bottoms is rotated, cut outstanding lumbar intervertebral disc, after the taking-up inner and outer sleeves, the lumbar intervertebral disc taking-up that will downcut with the vertebral pulp pincers gets final product.
This utility model is simple in structure, easy to use, the lumbar intervertebral disc of can either disposable excision deviating from, and effectively neuroprotective root and spinal dura mater are saved operating time again, have reduced operation risk, can be widely used in that lumbar intervertebral disc takes out in the operation in the hospital.
