Abstract
The utility model provides an adjustable quick detach formula backbone fixing device, including two horizontal bracing pieces that are located on the same straight line, two the equal slidable mounting of relative one end of horizontal bracing piece fixes through a fastening bolt in same sliding tube and respectively, each the equal fixed mounting of free end of horizontal bracing piece has a backbone fix with screw cover, each backbone fix with screw cover all is equipped with a backbone mounting screw chamber, each along vertical direction all be equipped with a backbone screw through -hole on the horizontal bracing piece, backbone screw through -hole and backbone mounting screw chamber one -to -one and coaxial setting, each a backbone screw is all installed with the detachable mode to backbone mounting screw intracavity. The utility model discloses convenient fixed backbone, convenient to use in the surgery operation, device simple structure improves the anti effect of revolving of centrum greatly, the simultaneously very big operation time that has shortened.
Description
Technical field
This utility model relates to spinal column section Special medical equipment technical field, especially relates to a kind of adjustable quick dismountable formula spinal fixation system.
Background technology
Heredity, abnormal development, wound, chronic stress and tumor and Other diseases all can cause the pathological condition of spinal column, and these pathological symptoms can reduce the pliability of spinal column and limit the range of movement of spinal column.Adopt surgery internal fixation operation that above-mentioned pathological condition is treated the Therapeutic Method being medically commonly use at present.Spinal set screw has the disadvantage in that in the use procedure of above-mentioned orthomorphia because of individual variation and squeezes into the position of the spinal set screw that the reasons such as error make to squeeze into human body and produce little deviation unavoidably, and screw body and U-shaped nail seat interfix, therefore U-shaped nail seat position cannot be finely tuned, thus bringing great inconvenience to the clubs of putting of spinal column fixing rod；Multi-axial spinal screw has the disadvantage in that in the use procedure of above-mentioned orthomorphia the spherical head of screw body can rotate in spherically mounted chamber, namely screw body and U-shaped nail seat can do multi-axis turning, carry out strutting and during the orthotic procedure such as pressurization the anti-rotational effect of vertebral body poor, increase operating difficulty, consequently, it is possible to cause that final orthopedic effect is undesirable.
Utility model content
The utility model proposes a kind of adjustable quick dismountable formula spinal fixation system, facilitate spinal fixation, easy to use in surgical operation, apparatus structure is simple, is greatly improved the anti-swirl effect of vertebral body, shortens operating time greatly simultaneously.
The technical solution of the utility model is achieved in that adjustable quick dismountable formula spinal fixation system, including two transverse support bar being located along the same line, the opposite side of transverse support bar described in two is all slidably mounted in same sliding tube and fastens bolt respectively through one and fixes, the free end of each described transverse support bar is all installed with a spinal screw fixed cover, each described spinal screw fixed cover is vertically equipped with a spinal screw installation cavity, each described transverse support bar is equipped with a spinal screw through hole, described spinal screw through hole and spinal screw installation cavity one_to_one corresponding and be coaxially disposed, a spinal screw all it is detachably mounted with in each described spinal screw installation cavity.
Preferably, described spinal screw includes thread segment, smooth section and thread tapping section from top to bottom successively, is provided with baffle plate between described smooth section and thread tapping section, and described thread segment is provided with nut, and described smooth section is arranged in described spinal screw installation cavity.
Preferably, described in two, spinal screw is symmetrical arranged.
Have employed technique scheme, the beneficial effects of the utility model are: owing to adjustable quick dismountable formula spinal fixation system is when operation, two transverse support bar freely can regulate in sliding tube, can be adjusted according to spinal screw implantation position at any time, facilitate spinal fixation, in surgical operation easy to use, spinal screw fixed cover is provided with spinal screw installation cavity, it is detachably mounted with spinal screw in spinal screw installation cavity, this mounting means is greatly improved the anti-swirl effect of vertebral body, additionally after spinal screw is implanted, quickly transverse support bar and spinal screw can be installed together, shorten operating time greatly.
