Abstract
The utility model discloses an interbody fusion cage with elasticity, including under, plate body and connecting at last plate body two connecting plates between the plate body under, of parallel arrangement's last plate body, the shaping has the oval -shaped transversely to plant bone hole on two connecting plates, and that goes up that plate body and plate body middle part shaping down have a rectangle vertically plants bone hole, transversely plants bone hole and vertically plants bone hole vertical cross, and two connecting plates are in vertically plant bone hole's both sides, go up the plate body, down the plate body rear side be close to two connecting plates the position respectively the shaping have first screw hole, upward plate body, the middle shaping respectively of lower plate body rear end portion have a second screw hole. Go up the plate body, down the plate body is connected with the centrum of upper and lower position respectively, the connecting plate produces has certain mobility between the centrum that certain deformation made position from top to bottom, it has increased the deformed range of connecting plate part transversely to plant bone hole, and does benefit to the growth of bone grafting.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to one and has elastic Invasive lumbar fusion device.
Background technology
Existing intervertebral disc is both tough and tensile, full of elasticity again, when bearing pressure, is compressed, and after removing pressure, restore again, have the effect of similar " cushion ", available buffer external force, to the concussion of spinal column, also can increase the motion amplitude of spinal column.Along with the degeneration change of intervertebral disc is more and more serious, the spinal nerve compressing that Intervertebral Source causes also is the main cause of clinical neck-shoulder pain, lumbago and leg pain.Although it is satisfied to the short term efficacy of discogenic disease that intervertebral reaches Bony union by bone grafting or intervertebral fusion, but there is part intervertebral bone graft not merge, Invasive lumbar fusion device displacement, depression, the intervertebral disc degeneration of adjacent segment accelerates, and fixed-segment is stiff, late result is also unsatisfactory.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, provides a kind of simple and reasonable, is beneficial to bone-graft fusion, is connected firmly and makes fixed-segment possess the Invasive lumbar fusion device of certain mobility.
For realizing the object of this utility model, being achieved by the following technical solutions: one has elastic Invasive lumbar fusion device, including the upper plate body, lower body and two connecting plates being connected between upper plate body, lower body that be arranged in parallel; Two connecting plates form oval horizontal bone grafting hole, form longitudinal bone grafting hole of rectangle in the middle part of upper plate body and lower body, horizontal bone grafting hole and longitudinal bone grafting hole square crossing, two connecting plates are in the both sides in described longitudinal bone grafting hole; Form a front side breach on front side of described upper plate body, lower body and between connecting plate, on rear side of described upper plate body, lower body and between connecting plate, form a rear side breach; Position near two connecting plates on rear side of described upper plate body, lower body forms the first screw hole respectively; Form the angle of 40-50 degree between the axis of two the first screw holes on upper plate body, and the axis of these two the first screw holes intersects above upper plate body; Also form the angle of 40-50 degree between the axis of two the first screw holes on lower body, and the axis of these two the first screw holes intersects below lower body; Form second screw hole respectively in the middle of described upper plate body, lower body rearward end, form the angle of 70-80 degree between the second screw hole axis and upper plate body, and the axis of the axis of the second screw hole and the first screw hole is non-intersect.
Preferably: the upper surface of described upper plate body and the lower surface indention of lower body; Described upper plate body, lower body entirety are rectangular, and the summit, front end two of upper plate body, lower body is round-corner transition.
Compared with prior art, the beneficial effects of the utility model are: be connected by connecting plate between described upper plate body, lower body, upper plate body, lower body are connected with the vertebral body of upper-lower position respectively, and connecting plate produces certain deformation and makes to have certain mobility between the vertebral body of upper-lower position; What horizontal bone grafting hole added connecting plate part can deformation amplitude, and is beneficial to the growth of bone grafting.Be provided with the first screw hole and second screw hole of different angles in addition, after attachment screw and vertebral body are fixed, upper plate body, lower body and upper hypocentrum are connected firmly stable.

Detailed description of the invention
With reference to the accompanying drawings detailed description of the invention of the present utility model is made a detailed explanation below.
According to Fig. 1, the present embodiment is that one has elastic Invasive lumbar fusion device, includes the upper plate body 1, lower body 3 and two connecting plates 2 being connected between upper plate body, lower body that be arranged in parallel; Two connecting plates form oval horizontal bone grafting hole 6, form longitudinal bone grafting hole 7 of rectangle in the middle part of upper plate body and lower body, horizontal bone grafting hole and longitudinal bone grafting hole square crossing, two connecting plates are in the both sides in described longitudinal bone grafting hole; Form a front side breach 8 on front side of described upper plate body, lower body and between connecting plate, on rear side of described upper plate body, lower body and between connecting plate, form a rear side breach 9; Position near two connecting plates on rear side of described upper plate body, lower body forms the first screw hole 4 respectively; Form the angle of 40-50 degree between the axis of two the first screw holes on upper plate body, and the axis of these two the first screw holes intersects above upper plate body; Also form the angle of 40-50 degree between the axis of two the first screw holes on lower body, and the axis of these two the first screw holes intersects below lower body; Form the angle forming 70-80 degree between second screw hole 5, a second screw hole axis and upper plate body respectively in the middle of described upper plate body, lower body rearward end, and the axis of the axis of the second screw hole and the first screw hole is non-intersect.
The upper surface of described upper plate body and the lower surface indention of lower body; Described upper plate body, lower body entirety are rectangular, and the summit, front end two of upper plate body, lower body is round-corner transition.
Be connected by connecting plate between described upper plate body, lower body, upper plate body, lower body are connected with the vertebral body of upper-lower position respectively, and connecting plate produces certain deformation and makes to have certain mobility between the vertebral body of upper-lower position; What horizontal bone grafting hole added connecting plate part can deformation amplitude, and is beneficial to the growth of bone grafting.Be provided with the first screw hole and second screw hole of different angles in addition, after attachment screw and vertebral body are fixed, upper plate body, lower body and upper hypocentrum are connected firmly stable.
When installing this Invasive lumbar fusion device, first use screw to be fixed through the vertebral body of the second screw hole and correspondence position, screw is not screwed to position completely; Then use screw to be fixed through the vertebral body of the first screw hole and correspondence position, screw is screwed to position completely; Finally again the screw of the second screw hole is tightened completely.
