Above-mentioned disclosed document can solve some problems of deformity of spine, but to be the rectification effect that has undesirable for the shortcoming existed, and some complex structures, complicated operation, practicality is strong, and what really should use is few.To sum up, the orthotics of the deformity of spine emerged in an endless stream develops into from Kazakhstan, Lu Shi rod the process that pedicle nail bar system popular Now Domestic is gradual perfection, but the defect of its technology is apparent, the former easily gets loose by apparatus, and the latter's operation technique is complicated, it needs to insert pedicle nail, often need to open canalis spinalis, osteotomy be orthopedic, to technical merit and skill requirement high, operation risk is large, easily cause the severe complications such as paraplegia, be therefore difficult to promote the use to basic hospital.
Summary of the invention
Object of the present invention is exactly the deficiency overcoming existing orthotics, and provides brand-new a kind of apparatus taking memorial alloy as material formation and be exclusively used in deformity of spine rectification.
The present invention is achieved through the following technical solutions:
A kind of deformity of spine orthotics, it is characterized in that: this apparatus is by making the marmem of implant into body spinal column, it comprises coupler body, Universal-head and vertical rod, described Universal-head and coupler body are an entirety, both sides Universal-head is separately positioned on the left and right sides shoulder of coupler body, Universal-head is hollow cylinder, and cylinder has U-lag, and the medial surface of U-lag is provided with screw thread; Described vertical rod is a solid cylinder, and vertical rod is placed in the U-type groove of Universal-head, and the diameter of barred body and the U-lag set by Universal-head match, and are fixed by bolt; The shape of described coupler body is arc, and the two ends of coupler body are provided with crotch, and the center below the arch roof of coupler body is provided with a longitudinal fluting.
Described longitudinal fluting effect is convenient to bending to mate size required for patient and bending can be made to concentrate on coupler body groove, thus do not affect the structure at other positions.
The direction of the crotch at above-described coupler body two ends is symmetric form shape.
The direction of the crotch at described coupler body two ends is left asymmetric type shape.
The direction of the crotch at described coupler body two ends is right asymmetric type shape.
The length of described vertical rod is need the lopsided spine lengths of correcting to match.
Above-described deformity of spine orthotics, described coupler body is several, and vertical rod matches with the U-type groove of each coupler body Universal-head, and series connection is integrated.That the lopsided spinal column corrected as required settles several coupler bodies during use, rod and coupler body cooling will be indulged, curve required form, be buckled in spinal column both sides transverse process or vertebral plate after crotch opens, rewarming palintrope hooks clasp and embraces and not easily get loose, then is arranged on by vertical rod in the U-type groove of Universal-head of several coupler bodies, and by the locking of bolt appropriateness, form three-dimensional correction structure, can recover strong after vertical excellent rewarming, can progressively correct lopsided spinal column as required.
Described marmem is can the Nickel-titanium alloy for medical purpose of implant into body, and the weight ratio of Ti: Ni is 1: 1-1.5, can also add other element in right amount as required, such as copper, aluminum and zinc etc.
Tool of the present invention has the following advantages and brings many beneficial effects:
1, this apparatus take memorial alloy as material, and its structure is by coupler body, Universal-head, vertical bar construction; Wherein, Universal-head and coupler body are an entirety, and both sides Universal-head is separately positioned on the left and right sides shoulder of coupler body, and vertical rod is placed in the U-type groove of Universal-head, and be fixed firmly by bolt; The crotch at coupler body two ends can also become symmetric form, left asymmetric type, right asymmetric type three kinds of shapes according to different Demand Design.Each age group can be widely used in, the corrective procedure of deformity of spine that a variety of causes causes.Feature of the present invention is simple to operate, only need operate on transverse process or vertebral plate, and do not need to insert pedicle nail, also unnecessaryly open canalis spinalis, the advantage of the crotch of designed memorial alloy composition, vertical rod and Universal-head can be given full play to, complicated operation is become simple installation process, simplify operation, shorten operating time, greatly reduce operation risk, very easily promote to the basic hospital that condition is simple and crude, and have larger practical value and wide application prospect.
2, apply the present invention, by exposure transverse process or vertebral plate, crotch is installed and can completes orthomorphia, simplify operation, reduce operation risk.
3, by crotch being designed to the shape of pawl, convenient operation, be easy to firmly encircle effective anti-locking hook.
4, coupler body both sides of the present invention shoulder is provided with Universal-head, is convenient to vertical rod to be mounted on Universal-head, easy to operate, shorten operating time.
5, the center below coupler body arch roof of the present invention is designed with a longitudinal fluting, is convenient to bending to adapt to a different size standby installation.
6, crotch of the present invention, the vertical bar material of Universal-head memory are memorial alloy composition, any bending of deliquescing when memorial alloy feature is cooling, and it is strong fixing to recover warm rear recovery; Utilize memorial alloy feature, be convenient to crotch to open insert transverse process or vertebral plate, install rear immersion warm water rewarming and hook can be made firmly to encircle transverse process or vertebral plate not easily gets loose; In addition, described vertical bar material is that memorial alloy is made, and is equally to utilize the golden feature of memory note, by its random bending when cooling, is convenient to be mounted in Universal-head.
7, in the present invention, the crotch at coupler body two ends can also become symmetric form, left asymmetric type, right asymmetric type three kinds of shapes according to different Demand Design, the rectification of different maleformation can be met, hook system size is divided into large, medium and small three series, and the size of the different size of each series segmentation is to meet the patient of Different age group.
