Abstract
The utility model discloses a thoracic-lumbar vertebra anterior steel plate comprising a steel plate, wherein the middle part of the steel plate is provided with a strip-shaped hole, and a third fixing screw penetrates through the strip-shaped hole, and is locked by a third nut. The middle part of the thoracic-lumbar vertebra anterior steel plate is provided with the strip-shaped hole; the third fixing screw penetrates through the strip-shaped hole and is locked by the third nut; and during the use of the steel plate, the third fixing screw is fixed with a prosthesis on a corresponding thoracic-lumbar vertebra, and the third nut is used for locking the third fixing screw, so that the prosthesis is prevented from loosening, and the health and safety of a human body are guaranteed. Due to the arrangement of the strip-shaped hole, the third fixing screw is convenient to move up and down; and an optimum fixed position can be determined by adjusting the position of the third fixing screw in the strip-shaped hole.
Description
Technical field
This utility model relates to a kind of fixture of medical fixedly breast lumbar vertebra, relates in particular to a kind of breast lumbar vertebra anterior plate.
Background technology
Existing breast lumbar vertebra anterior plate comprises steel plate; One end of steel plate is provided with two circular ports; The first main hold-down screw passes one of them circular port and passes through first nut check; The first auxilliary hold-down screw passes another circular port; The other end of steel plate is provided with two end bar shaped shoulder holes, and the second main hold-down screw passes one of them bar shaped shoulder hole and uses second nut check, and the second auxilliary hold-down screw passes another bar shaped shoulder hole; During use with the first main hold-down screw, the first auxilliary hold-down screw and corresponding breast lumbar vertebra is fixed and with first nut with the first main hold-down screw locking, the second main hold-down screw, second is assisted hold-down screw and corresponding breast lumbar vertebra is fixed and with second nut second main hold-down screw is locked.But the problem that existing steel plate exists is the fixture that is not provided with on the steel plate the breast lumbar prosthesis, and along with human motion, prosthese is loosening easily.
The utility model content
The technical problem that this utility model will solve provides a kind of breast lumbar vertebra anterior plate that prevents prosthetic loosening.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of breast lumbar vertebra anterior plate comprises steel plate, and the middle part of wherein said steel plate is provided with bar hole, and the 3rd hold-down screw passes bar hole also with the 3rd nut check.
The breast lumbar vertebra anterior plate of this utility model, wherein said the 3rd hold-down screw is a soket head cap screw.
The middle part of this utility model breast lumbar vertebra anterior plate is provided with bar hole; The 3rd hold-down screw passes bar hole also with the 3rd nut check; During use the 3rd hold-down screw is fixed and with the 3rd nut the 3rd hold-down screw locked with the prosthese on the corresponding breast lumbar vertebra; Prevent prosthetic loosening, guaranteed the healthy and safe of human body.Upper and lower the moving of convenient the 3rd hold-down screw of bar hole is set, regulates the position of the 3rd hold-down screw in bar hole, can confirm optimum fixation position.
Description of drawings
Fig. 1 is the axonometric chart of this utility model breast lumbar vertebra anterior plate.
The specific embodiment
As shown in Figure 1; This utility model breast lumbar vertebra anterior plate comprises steel plate 1, and an end of steel plate 1 is provided with two circular ports, and the first main hold-down screw 2 passes one of them circular port and locks through first nut 3; The first auxilliary hold-down screw 4 passes another circular port; The other end of steel plate 1 is provided with two bar shaped shoulder holes, 5,6, the second main hold-down screws 7 and passes one of them bar shaped shoulder hole 5 also with 8 lockings of second nut, and the second auxilliary hold-down screw 9 passes another bar shaped shoulder hole 6; The middle part of steel plate 1 is provided with bar hole 10, the three hold-down screws 11 and passes bar hole 10 also with 12 lockings of the 3rd nut.First main hold-down screw 2, first auxilliary hold-down screw 4, second main hold-down screw 7, the second auxilliary hold-down screw 9, the 3rd hold-down screw 11 all are soket head cap screws.The bottom of first nut 3, second nut 8, the 3rd nut 12 is provided with the pad that is made into integration with nut.
During use first main hold-down screw 2, the first auxilliary hold-down screw 4 is fixed with corresponding breast lumbar vertebra and with first nut 3 the first main hold-down screw 2 locked; Second main hold-down screw 7, the second auxilliary hold-down screw 9 is fixed with corresponding breast lumbar vertebra and with second nut 8 the second main hold-down screw 7 locked; At last the 3rd hold-down screw 11 is fixed with the prosthese on the corresponding breast lumbar vertebra and the 3rd hold-down screw 11 is locked with the 3rd nut 12; According to different people breast lumbar structures; Can regulate the second main hold-down screw, 7, the second auxilliary position of hold-down screw 9 on bar shaped shoulder hole 5,6; Regulate the 3rd position of hold-down screw 11 in bar hole 10, to confirm optimum fixation position.
Above-described embodiment describes the preferred implementation of this utility model; Be not that scope to this utility model limits; Under the prerequisite that does not break away from this utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of this utility model all should fall in the definite protection domain of this utility model claims.
