Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of sclerotin grinding device.
Background technique
Lumbar vertebrae bears the function of load-bearing, movement and protection nerve, all illness for causing lumbar stability to be lost, such as vertebra
Disk bulging or protrusion, hyperplasia and lumbar instability, spinal canal stenosis etc., can all lead to pain in the loins, skelagia, numbness of lower limbs and row
Walk inconvenience, it is necessary to carry out spinal stability reconstruction.For a long time, lumbar spinal fusion is always clinical treatment low back pain and backbone
Whether successfully the important means of unstability illness has become whether fusion in most of spinal operations and judges operation main mark
One of standard.Posterior decompression posterior decompression bone grafting (PLIF) is to treat prominent one of the main means of lumber ertebral disc, by by the way of escape
The vertebral plate of excision accomplishes wedge-shaped bone block and plants in lumbar intervertebral, is restored intervertebral height with this, achieve good effect and is obtained
Rapid Popularization.
Specific operating procedure (by taking L5 ~ S1 operation as an example): waist Posterior midline approach appears L5 ~ S1 bilateral lamina and little Guan
Section cuts off the vertebral plate up and down each 1/2 or so of L5 ~ S1 centrum, 1/2 part on the inside of two sides excision Minor articulus, between excision vertebral plate
Ligamentum flavum appears dural sac and nerve root.Dural sac and nerve root are gently retracted with nerve hook, interverbebral disc is manifested, cuts
It opens fibrous ring and cuts off interverbebral disc, strike off interverbebral disc or more cartilage plate with cyclic annular floating rule, manifest terminal plate of vertebral body.Use intervertebral fusion
Device examination body determines the Invasive lumbar fusion device of suitable types, bites the vertebral plate of excision into pieces filling interbody space front, will insert respectively broken
In the fusion device implantation interbody space of bone, it to be used for subsequent fusion.Vertebral plate ecto-entad includes soft tissue layer, cartilage layers, cortex bone
Layer, cancellous bone layer, in operation, the processing for biting vertebral plate into pieces is usually to cut off the soft tissue of bony surface and cartilage, then use
Thick bone biting containing cortex bone and cancellous bone is cut into thin bone by hand to insert interbody space by rongeur.However, due to skin
The hardness of matter bone and cancellous bone is higher, and the thick bone quantity for needing to cut in operation is more, is carried out by hand with rongeur merely
Operation, on the one hand reduces procedure efficiency, on the other hand since to will lead to the sclerotin size after stinging bone inaccurate for manual operation, no
Meet operation to require to need rework operation, and medical staff can not enough cut in the state of performing the operation fatigue due to dynamics
The most thick bones of mill.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
Please refer to Fig. 1.The sclerotin of the utility model grinds device, including the first hinged support plate 2 and the second support plate
3, for second support plate 3 to carry thick bone, first support plate 2, which is equipped with, stings osteotome tool to what is cut to the thick bone
4, the osteotome tool of stinging is equipped with for molding hole 5, and first support plate 2 can be turned to substantially to be bonded with the second support plate 3
When, the thick sclerotin for stinging 4 the second support plate 3 of compression of osteotome tool is until making the thick sclerotin be cut into thin bone and making described thin
Bone shaping is in the molding hole 5.
In above embodiments, the folding realization for stinging 4 the first support plate 2 of cooperation of osteotome tool and the second support plate 3 is to thick
Bone is cut, and can both be operated to single thick bone, can also multiple thick bones be carried out while be operated simultaneously, improved and sting bone
Efficiency.
Sclerotin for the laborsaving operation of energy, the utility model embodiment grinds device, can also include solid with the first support plate 2
Surely the first in command 7 connected, the second handle 6 being fixedly connected with the second support plate 3, the first in command 7 and second handle 6 exist
It can be bonded when stinging bone.The arm of force for extending the first support plate 2 and the second support plate 3 can be reduced effectively using lever principle stings bone institute
The dynamics needed.
Since the required sclerotin hardness for stinging bone is higher, second support plate 3 is additionally provided with diamond layer 8, to avoid
After being used for multiple times, bone efficiency and quality are stung in the second support plate out-of-flatness reduction.
It further include that the elasticity being set in the molding hole 5 pushes away in order to which the sclerotin removal molding hole 5 for stinging bone will be completed
Plate 9, the elastic pusher 9 are connect with the first support plate 2 by spring, when the first support plate 2 is substantially bonded with the second support plate 3
When, the spring is in most compressed state, and after completing deep, the spring will be described by restoring deformation generation elastic force
Sclerotin fragment removes the molding hole 5, in this way without manual operation, the sclerotin for stinging bone can will both be completed and removed molding hole 5, just
Benefit and health.
To meet the Particle size requirements that posterior decompression posterior decompression bone grafting (PLIF) cuts sclerotin, the molding hole 5 is straight
Diameter is 0.1 ~ 1.0 mm.
It further includes the pedestal 12 for fixing the second support plate 3 that the sclerotin, which grinds device, when bone operation is stung in execution, bottom
Seat bestows support force, the deep operation of completion that can be more firm.
Well known any form with cutting function can be used in the shape of above-mentioned cutter.But in order to meet other operations pair
Sting the Particle size requirements of bone, the osteotome tool 4 of stinging is spliced by multiple knife combinations, and same described to sting osteotome tool 4 sliceable
Also detachable, when needing to cut out big partial size bone, the part cutter for stinging osteotome tool 4 can be dismantled, when needing to cut out granule
When diameter bone, the part cutter dismantled can be spliced again.
Since the requirement of deep dynamics is very big, compare the situation for dynamics deficiency occur, the first in command 7 is connected with manually
Rocker arm 10, it is described equipped with that can be connected to and match that the hand-operated rocker arm 10 is equipped with external screw thread, the first in command 7 and second handle 6
Externally threaded through-hole, the hand-operated rocker arm 10 can be run through by the through-hole is bolted in the first in command 7 and second handle 6,
When the first in command 7 and second handle 6 are bonded, hand-operated rocker arm 10 can be rotationally advancing by through-hole, utilize screw threads for fastening the
The compactness of leader 7 and second handle 6.
In order to reinforce hand-operated rocker arm 10 to the fitting intensity of the first in command 7 and second handle 6, the hand-operated rocker arm 10 is also matched
There is the nut 11 for fastening, after completing hand-operated rocker arm 10 to the fastening of the first in command 7 and second handle 6, nut 11 can be into
One step reinforces hand-operated rocker arm 10 to the fitting intensity of the first in command 7 and second handle 6, to increase deep dynamics.
It is not directed to place above, is suitable for the prior art.
The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute
Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar
Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
