Description
Technical field
This utility model relates to orthopedic medical device technical field, particularly relates to a kind of new spinal fixture.
Background technology
In recent years, along with spinal biomechanics research and the development of material science, internal fixation of spine technology is in spinal column degenerative disease, tumor of spine, wound to such an extent as to be widely applied in the operative treatments such as Spondylitis.
The traditional method that spinal column is fixed is the spine portion adopting the spinal fixation system of rigidity to support, and prevents impaired spine portion to be moved.The spinal fixation system adjustable extent of prior art is too little, although there has also been flexible design, the connector of flexibility is easy to mechanical breakdown occur, the durability that spinal column can not be provided long-term and stability.Due to existing spinal fixation system, to there is adjustable extent little, durability and stability low, maintenance cost is high, the problem that service life is short.
Therefore, invent a kind of new spinal fixture tool and seem very necessary.
Utility model content
In order to solve the problems of the technologies described above, this utility model provides a kind of new spinal fixture, and to solve existing spinal fixation system, to there is adjustable extent little, durability and stability low, maintenance cost is high, the problem that service life is short.A kind of new spinal fixture, comprises pedicle nail, longitudinal rod, transverse bar, lock screw, head of screw, longitudinal rod through hole, transverse bar through hole.Described pedicle nail is arranged on the bottom of head of screw; Described lock screw is arranged on the top of head of screw; Longitudinal rod through hole and transverse bar through hole is provided with in described head of screw; Match with head of screw through longitudinal rod through hole in the two ends of described longitudinal rod; Match with head of screw through transverse bar through hole in the two ends of described transverse bar.
The middle part of described longitudinal rod is provided with stretch section, can fixedly provide long-term durability and stability, be conducive to reducing maintenance cost, improve service life for spinal column flexibility.
The middle part of described transverse bar is provided with stretch section, can fixedly provide long-term durability and stability, be conducive to reducing maintenance cost, improve service life for spinal column flexibility.
One end of described longitudinal rod is provided with vernier knob, can expand range of accommodation, improves the fixing durability of spinal column flexibility and stability.
One end of described transverse bar is provided with vernier knob, can expand range of accommodation, improves the fixing durability of spinal column flexibility and stability.
Described longitudinal rod through hole is arranged on the top of transverse bar through hole, and described longitudinal rod through hole is connected with transverse bar through hole, convenient fixing, is conducive to reducing maintenance cost, improves service life.
The beneficial effects of the utility model are: by the setting of stretch section and vernier knob, can expand range of accommodation, further for spinal column flexibility fixedly provides long-term durability and stability, are conducive to reducing maintenance cost, raising service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described further:
In figure:
1-pedicle nail, 2-longitudinal rod, 3-transverse bar, 4-lock screw, 5-head of screw, 6-longitudinal rod through hole, 7-transverse bar through hole, 8-stretch section, 9-vernier knob.
Embodiment:
A kind of new spinal fixture as shown in Figure 1, to solve existing spinal fixation system, to there is adjustable extent little, durability and stability low, maintenance cost is high, the problem that service life is short.A kind of new spinal fixture, comprises pedicle nail 1, longitudinal rod 2, transverse bar 3, lock screw 4, head of screw 5, longitudinal rod through hole 6, transverse bar through hole 7.Described pedicle nail 1 is arranged on the bottom of head of screw 5; Described lock screw 4 is arranged on the top of head of screw 5; Longitudinal rod through hole 6 and transverse bar through hole 7 is provided with in described head of screw 5; Match with head of screw 5 through longitudinal rod through hole 6 in the two ends of described longitudinal rod 2; Match with head of screw 5 through transverse bar through hole 7 in the two ends of described transverse bar 3.
The middle part of described longitudinal rod 2 is provided with stretch section 8, can fixedly provide long-term durability and stability, be conducive to reducing maintenance cost, improve service life for spinal column flexibility.
The middle part of described transverse bar 3 is provided with stretch section 8, can fixedly provide long-term durability and stability, be conducive to reducing maintenance cost, improve service life for spinal column flexibility.
One end of described longitudinal rod 2 is provided with vernier knob 9, can expand range of accommodation, improves the fixing durability of spinal column flexibility and stability.
One end of described transverse bar 3 is provided with vernier knob 9, can expand range of accommodation, improves the fixing durability of spinal column flexibility and stability.
Described longitudinal rod through hole 6 is arranged on the top of transverse bar through hole 7, and described longitudinal rod through hole 6 is connected with transverse bar through hole 7, convenient fixing, is conducive to reducing maintenance cost, improves service life.
The beneficial effects of the utility model are: by the setting of stretch section and vernier knob, can expand range of accommodation, further for spinal column flexibility fixedly provides long-term durability and stability, are conducive to reducing maintenance cost, raising service life.
Utilize technical scheme described in the utility model, or those skilled in the art being under the inspiration of technical solutions of the utility model, designing similar technical scheme, and reach above-mentioned technique effect, is all fall into protection domain of the present utility model.
