Above-mentioned disclosed document can solve some problems of deformity of spine, and the shortcoming that still exists is that the rectification effect that has is undesirable, the complex structure that has, and complicated operation, practicality is not strong, and what really should use is few.To sum up, it is the process of gradual perfection that the orthotics of the deformity of spine that emerges in an endless stream develops into pedicle nail bar system popular outside the Now Domestic from Ha Shi, Lu Shi rod, yet the defective of its technology is apparent, and the former gets loose by apparatus easily, and latter's operation technique is complicated, it need to insert pedicle nail, often need to open canalis spinalis, osteotomy is orthopedic, technical merit and experience is required high, operation risk is large, cause easily the severe complications such as paraplegia, therefore be difficult to promote the use to basic hospital.
Summary of the invention
Purpose of the present invention is exactly the deficiency that overcomes existing orthotics, and provides brand-new a kind of formation take memorial alloy as material to be exclusively used in the apparatus that deformity of spine is corrected.
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 to be made by marmem that can the implant into body spinal column, it comprises coupler body, Universal-head and vertical rod, described Universal-head and coupler body are an integral body, the 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-shaped groove of Universal-head, and the set U-lag of the diameter of barred body and Universal-head matches, and is fixed by bolt; Being shaped as 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 to be convenient to bending with the coupling required size of patient and can to make bending concentrate on the coupler body groove, thereby does not affect the structure at other positions.
The direction of the crotch at above-described coupler body two ends is the symmetric form shape.
The direction of the crotch at described coupler body two ends is the asymmetric shape in left side.
The direction of the crotch at described coupler body two ends is the asymmetric shape in right side.
The length of described vertical rod matches for the lopsided spine lengths that needs to correct.
Above-described deformity of spine orthotics, described coupler body are several, and vertical rod matches with the U-shaped groove of each coupler body Universal-head, and series connection is integrated.That the lopsided spinal column of correcting is as required settled several coupler bodies during use, to indulge the cooling of rod and coupler body, curve required form, be buckled in spinal column both sides transverse process or vertebral plate after crotch opens, the rewarming palintrope hooks clasp and embraces and be difficult for getting loose, and will indulge in the U-shaped groove of Universal-head that rod is installed in several coupler bodies again, and by the locking of bolt appropriateness, consist of the three-dimensional correction structure, can recover strong behind the vertical excellent rewarming, can progressively correct lopsided spinal column as required.
Described marmem be can implant into body Nickel-titanium alloy for medical purpose, the weight ratio of Ti: Ni is 1: 1-1.5 can also add other element, such as copper, aluminum and zinc etc. as required in right amount.
The present invention has following advantage and brings many beneficial effects:
1, this apparatus is 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 integral body, and the both sides Universal-head is to be separately positioned on the left and right sides shoulder of coupler body, and vertical rod is to be placed in the U-shaped groove of Universal-head, and is fixed firmly by bolt; The crotch at coupler body two ends can also become according to different Demand Design symmetric form, asymmetric, the asymmetric three kinds of shapes in right side in left side.Can be widely used in the corrective procedure of the deformity of spine that each age group, a variety of causes cause.Characteristics of the present invention are simple to operate, only need to operate at transverse process or vertebral plate, and need not insert pedicle nail, the also unnecessary canalis spinalis of opening can be given full play to the advantage of designed crotch, vertical rod and the Universal-head that forms with memorial alloy, complicated operation is become simple installation process, simplify operation, shortened operating time, greatly reduced operation risk, very easily promote to the simple and crude basic hospital of condition, and larger practical value and wide application prospect are arranged.
2, use the present invention, can finish orthomorphia by exposing transverse process or vertebral plate installation crotch, simplified operation, reduce operation risk.
3, by crotch being designed to the shape of pawl, convenient operation is easy to firmly encircle effectively anti-locking hook.
4, be provided with Universal-head at coupler body of the present invention both sides shoulder, be convenient to vertical rod is mounted on the 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 different size standby an installation.
6, the vertical bar material of crotch of the present invention, Universal-head memory is that memorial alloy forms, any bending of deliquescing when the memorial alloy characteristics are cooling, and it is strong fixing to recover warm rear recovery; Utilize the memorial alloy characteristics, be convenient to crotch opened and insert transverse process or vertebral plate, install rear immersion warm water rewarming and can make hook firmly encircle transverse process or vertebral plate is difficult for getting loose; In addition, described vertical bar material is that memorial alloy is made, and is equally to utilize the golden characteristics of memory note, by its random bending when cooling off, is convenient to it is mounted in the Universal-head.
7, the crotch at coupler body two ends can also become according to different Demand Design symmetric form, asymmetric, the asymmetric three kinds of shapes in right side in left side among the present invention, can satisfy the rectification of different maleformations, the hook system size is divided into large, medium and small three series, and the size of the different sizes of each series segmentation is to satisfy the patient of all ages and classes section.
