Abstract
The invention relates to a power-driven automatic stretching correcting system and application thereof. The power-driven automatic stretching correcting system comprises two titanium rods, springs, a fixable connector, a locking screw, pedicle screws and plug screws. One ends of the two titanium rods are connected by the connector and are fixed to a vertebral body through the locking screw. Each of the other ends of the two titanium rods is fixed to the vertebral body through one pedicle screw with one plug screw. Connectors can be added according to needs. Springs can be disposed on the titanium rods. One end, away from the corresponding pedicle screw and extending out of the connector, of each titanium rod is a sliding free end. The invention further discloses application of the correcting system in the technical field of children scoliosis correction and fixation. The power-driven automatic stretching correcting system has the advantages that stable internal fixation can be achieved by the screw-rod system, automatic stretching of the system can be kept by extension of the springs on the titanium rods and sliding between the titanium rods and the connectors, a growth function of a spine can be kept without multiple extending operations, correcting effect for scoliosis can be well kept, and complication incidence rate can be reduced.
Description
[technical field]
The present invention relates to the orthopedic medical device technical field, specifically, is that a kind of power struts orthopedic system and application thereof automatically.
[background technology]
Along with to the deep understanding of the three-dimensional deformity of scoliosis and the development of internal fixation of spine technology, the operation rectification effect of teenagers scoliosis has had obvious progress in recent years.From early stage Harrington corrective method, Luque corrective method, Harrington-Luque combination method, Rachiocampis correction art and three-dimensional correction art (such as C-D operation, CDH art) are gone to rotate in front road finally, operation technique is corrected more and more easily, and rectification effect is also become better and better.But the treatment of the scoliosis in children that still has larger growth promoter potentiality is remained a difficult problem of field of spinal surgery.For this part patient, not only need effectively to correct deformity of spine, also need to keep the energy for growth of spinal column.The method that extensible rod is used for the treatment of child's scoliosis has been proposed at present, in succession occur such as antidotes such as " bayonet shape " cover pressing maneuver and Isola growth valve methods, but their shortcoming is still to need every 6 months to 1 year again operation to strut prolongation, make the child inevitably suffer the misery of Repeated Operation, also increased patient's financial burden simultaneously.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of power automatically to strut orthopedic system and application thereof.
The objective of the invention is to be achieved through the following technical solutions:
A kind of power struts orthopedic system automatically, but it comprises titanium rod, spring fixed connector, lock screw, pedicle nail and plug screw; The number of described titanium rod is two, but an end of two titanium rods is fixed on the vertebral body by lock screw by the fixed connector connection; The other end is fixed by pedicle screw and vertebral body with plug screw respectively; Can increase as required adapter therebetween; The part of stretching out adapter away from an end of pedicle screw on the titanium rod is the free sliding end
Have at least a titanium rod to need the assembling spring in the described system;
Described adapter is fixable adapter;
Described adapter can be various ways, as with the double parallel adapter of fixed function, single parallel adapter.
The present invention can be applicable to child's scoliosis orthopedic and technique for fixing field.
Of the present inventionly automatically strut elongation and titanium rod the slip at adapter connector place of function by spring and realize, spring when implanting on the titanium rod is in compressive state, growth spring with spinal column extends afterwards, and the titanium rod of spring inner slides at the adapter connector place, thereby makes titanium rod length between pedicle screw and adapter connector elongated and realized automatically strutting.
The present invention determines whether assembling spring and assembling particular location thereof according to difference operation case.
Compared with prior art, good effect of the present invention is:
One aspect of the present invention can play interior fixing effect by nail-bar system and keep stable, the on the other hand elongation by spring and spring are housed on the titanium rod and automatically the strutting property of the slip keeping system between titanium rod and adapter, it is extensibility, in the growth function that need not repeatedly to prolong preservation spinal in the situation of operation, the effect that can keep preferably scoliosis orthopedic reduces the complication sickness rate.
[description of drawings]
Fig. 1 schematic three dimensional views of the present invention (double parallel adapter);
Fig. 2 schematic three dimensional views of the present invention (two single parallel adapters).
Attached number in the figure is respectively: 1, titanium rod, 2, spring, 3, plug screw, 4, pedicle screw, 5, lock screw, 6, can fix double adapter, 7, can fix single adapter, 8, the free sliding end.
[specific embodiment]
Below provide a kind of power of the present invention automatically to strut the specific embodiment of orthopedic system and application thereof.
Embodiment 1
Accompanying drawing 1,2 be respectively adopt multi-form adapter and form of the present invention multi-form.And in every kind of form, the titanium rod is according to actual operation needs assembling spring.But the present invention is comprised of titanium rod 1, spring 2 fixed connectors 6 or 7, lock screw 5, pedicle screw 4 and plug screw 3.
The system of Fig. 1 for adopting double parallel adapter 6 to form.Two titanium rod 1 one ends pass respectively the two through hole of double parallel adapter 6, and adapter is fixed in vertebral body by lock screw 5.Adopt double parallel adapter assembling spring that various ways can be arranged, the upper end assembling all adopts assembling such as Fig. 1 C such as Figure 1A or lower end assembling such as Figure 1B or two ends.Select according to actual case, spring is inserted in the titanium rod, and be pressed in adapter connector place 6.The titanium rod other end is inserted on the U-shaped head of a nail of the pedicle screw 4 of implanting vertebral body, and is by plug screw 3 that itself and pedicle screw 4 is fixing, thereby fixes with vertebral body.The part of stretching out adapter away from an end of pedicle screw on the titanium rod is free sliding end 8.It is relevant that the tensile length of system and titanium rod stretch out the length of free sliding end 8 of adapter connector.
The system of Fig. 2 for adopting single parallel adapter 7 to form.System is provided with 7, two titanium rods of two single parallel adapters and passes respectively two single parallel adapters 7; Adapter 7 is fixed in vertebral body by lock screw 5.The titanium rod other end is fixed in pedicle nail 4 by plug screw 3 respectively, and then fixes with vertebral body.In two single parallel adapters, the parallel adapter of nearly pedicle screw and the locking of titanium rod, fricton-tight; Away between the parallel adapter of pedicle screw and titanium rod slidably, extension is free sliding end 8.The double parallel adapter is similar to adopting, and the tensile length of system is relevant with the length of free sliding end 8.
Must be pointed out the recessed side when the present invention is applied to treat child's Rachiocampis correction.
The above only is preferred implementation of the present invention; should be pointed out that for those skilled in the art, without departing from the inventive concept of the premise; can also make some improvements and modifications, these improvements and modifications also should be considered within the scope of protection of the present invention.
