Description
Technical field
The present invention relates to a kind of medical aid and its manufacturing methods, and in particular to a kind of cervical vertebra multifidus gap approach is double
Support plate and its manufacturing method between enabling spinous process.
Background technique
Stenosis has seriously affected people's lives quality, and the modus operandi for treating spinal canal stenosis includes neck
Preceding road, the way of escape and front and back road Spinal canal decompression, wherein neck posterior approach effect is preferable for long segment spinal canal stenosis.
However at present clinically common fixation, reconstruction biomaterials are mainly cervical vertebra single open-door fixed plate, and double door is consolidated
Fixed board is rarely found.Double door is to expand canalis spinalis from center, then sutures vertebral plate and ipsilateral paraspinal muscle or uses hydroxy-apatite stone material
Material fusion spinous process closes canalis spinalis, so that the canalis spinalis being extended is maintained.But current single open-door and double door technology requires
Supraspinous paraspinal muscle stop is first removed in art to be completed, and as described in Figure 1, stop is located at the paravertebral muscles group of cervical spine
(semispinal muscle of neck, multifidus and spinal muscle of neck) have the effects that control neck extend back, buckling and maintain body posture, these muscle groups
Stop is difficult to rebuild after being stripped, and can generate the bad complication such as axial pain, Wry Neck inability.Therefore, cervical vertebra rear vertebra
The effect of other flesh is increasingly taken seriously, and the cervical vertebra Double-door expansive laminoplasty through spatium intermusculare approach is without removing
Supraspinous muscle stop is first rived from stringer between spinous process to canalis spinalis gap, then after cervical vertebra is completed in the gap of paravertebral muscles group
The operation of road double door, remains the start-stop point of cervical vertebra rear paravertebral muscles group, maintains the physiology of rear muscle ligament complex
Structure reduces wound, avoids the generation of related bad complication.
However, there is no corresponding fixation device at present.
Summary of the invention
The present invention provides that a kind of structure is simple, and easy to use, fixed effect is obvious to solve the above-mentioned problems, can be not required to
Removing supraspinous muscle stop can be to the cervical vertebra multifidus gap approach double door spinous process that expansion canalis spinalis plays a supportive role
Between support plate.
The technical solution of the present invention is as follows:
Support plate between a kind of approach double door spinous process of cervical vertebra multifidus gap, which is characterized in that be made, wrap of pure titanium material
Include lateral supporting element, institute's supporting element include it is multiple be connected to collinear annular element I in turn, the both ends of the supporting element are equal
Equipped with fixing piece, fixing piece be it is multiple be connected to collinear annular element II in turn and connect with fixing piece bending, supporting element two
The fixing piece bending direction at end is identical, and angle is obtuse angle between supporting element and fixing piece, the supporting element and fixing piece one at
Type.
Further, screw thread is equipped in the annular element II.
Further, the annular element I is 3, and the annular element II is located at each 2 of fixing piece both ends.
Further, the within angle of the supporting element and any fixing piece is 100 ~ 170 °.
Further, the annular diameters of the annular element I and annular element II and be 1:2 with the diameter ratio of outer ring.
The manufacturing method of support plate between a kind of approach double door spinous process of cervical vertebra multifidus gap:
Step 1, selection
Select the pure titanium blank for meeting GB/T13810-2007 standard requirements.
Step 2, machine-shaping
Pure titanium blank is put into progress first time heating in resistance furnace, the condition for being first 750 DEG C~800 DEG C in temperature
Lower heat preservation 60min~90min keeps the temperature 300min~450min after then heating to 1000 DEG C~1050 DEG C；
Ingot casting after heating for the first time carries out the upsetting pull forging of a fire time, obtains with a thickness of 100mm~120mm
Slab；
The surface defect of the slab is removed, then the slab after removal surface defect is placed in heating furnace, in temperature
150min~280min is kept the temperature under conditions of being 850 DEG C~880 DEG C carries out second of heat treatment；
The slab after being heat-treated for the second time is rolled using hot-rolling mill, is obtained with a thickness of the half of 3mm~5mm
Finished product plate；
Step 3, it punches, cut.
The circular hole of φ 0.5cm is got at each circular cell center using titanium plate laser-beam drilling machine, forming ring structure is
The strip boards of single-phase company, then every 7 annulus cutting sections are at titanium plate section.
Step 4, it mills, tapping, polishing, bending and forming.
Utilize the corner burr of ceramic grinding mill polishing titanium plate section edge remnants, every section of both ends in the arc-shaped, both ends of polishing
Two annulus carry out tapping, numerical control titanium plate bending machine by titanium plate section both ends from two circular ring structures, to 60 ° of ipsilateral bending,
Form wings.
Advantageous effect of the invention are as follows:
After riving for posterior cervical spinous process in laminoplasty, it is supported between the two sides spinous process rived, has
It is to be applied to split with performances and good bioactivity and the biocompatibility such as the matched mechanical strength of human body bone and toughness more
The effective and feasible support construction of spatium intermusculare approach art formula had not only protected cervical vertebra rear muscle ligament complex structure, but also realization pair
The support of canalis spinalis expands, and effectively controls the decompression problem that canalis spinalis is closed the door again, for the widened firm and effective integration of canalis spinalis enabling
Provide guarantee.
Meanwhile supporting element and fixing piece are made of annular element, and supporting element is allow to measure door opening width by annular element I
With the observation to intraspinal tube, annular element II inner ring has screw thread that screw via through holes can be made to be fixed on spinous process sclerotin.
