Abstract
The utility model relates to a thorn steel plate adjusting fixing device for treating orthopedic vertebra which forms orthopedic chest and lumbar vertebra traumatic or pathologic fracture and dislocation, comprising a thorn steel plate, screws, cap nuts, adjusting screw rods and adjusting cap nuts. Upper three vertebral bodies and lower three vertebral bodies on a diseased part respectively form a firm integral body through the thorn steel plate, the screws, and the cap nuts. A gap on the diseased part is opened or shortened through the adjusting screw rods and the adjusting cap nuts, and then a corresponding cap nut is tightly screwed to make an entire vertebral column become a firm and reliable integral body. The utility model provides an inner fixing device for clinicians; the inner fixing device has shallow installation position and simple operation; the inner fixing device can be opened and tightly fixed.
Description
This utility model belongs to the traumatic and pathologisch Bruch of a kind of treatment orthopaedics breast lumbar vertebra, the internal fixation medical apparatus and instruments of dislocation.
Before this utility model, had the spinous process steel plate, Ha Shi rod and vertebral body fixation steel plate.They are because the fixedly spinous process that has can not strut or compression adjustment, and anti-torsion ability is poor; Though what have can strut vertebral body, the vertebral body number that struts is more, easily is strayed into spinal cavity and increases the weight of damage, easily breaks off relations complicated operation; The fixed position that also has is darker, easily is strayed into the thoracic cavity or the abdominal cavity of front, and the nervus vasculairs that easy damaged is big are so influenced their practicality.
The purpose of this utility model is to provide that a kind of to have a device position more shallow, simple to operate, can strut or compress the diseased region gap, and fixed inner fixer.
This utility model is finished as follows.Spinous process steel plate (1) and (2) connect and compose up and down through screw (3) that each is a pair of, by regulating integral body of Luo bar (5) and Luo medicated cap (6) formation.
In conjunction with the accompanying drawings utility model is described earlier:
Fig. 1 is a positive bitmap of the present utility model.
Fig. 2 is a positive bitmap of going up a pair of right side spinous process steel plate.
Fig. 3 is a side bitmap of going up a pair of left side spinous process steel plate.
With reference to Fig. 1, Fig. 2, Fig. 3 part is simply introduced.The spinous process steel plate is regulated all parts of holder and is all made by same stove rustless steel.Fig. 2 spinous process steel plate last a pair of be to be contained in the spinous process right side, a pair of spinous process left side that is contained in of infra.Fig. 3 spinous process steel plate last a pair of be to be contained in spinous process left side, a pair of spinous process right side that is contained in of infra.The length of spinous process steel plate * wide * thick=90 * 12 * 3mm
3, length can be divided several models according to height.Spinous process steel plate side position is circular-arc and coincide with the vertebra waist is bent, and slotted hole is arranged above it, and the spinous process of distance and vertebral body coincide.Crooked side plate length * wide * thick=15 * 12 * 3mm of spinous process steel plate
3,, a Luo hole is arranged above it, diameter is 5.5mm or 6.5mm.Screw Luo medicated cap on the spinous process steel plate is the 4mm standard component, and its screw length is 24mm.Regulating Luo bar Luo medicated cap is 5mm or 6mm standard component.Its Luo pole length is decided to sting except that the length of pathological changes vertebral plate or vertebral body, and nearly stage casing the other side's filing is long * dark=6 * 0.5mm
2
How device is done just slightly to introduce with this utility model.After the vertebral body bone of pathological changes had resetting of displacement, sting except that adnexaes such as the spinous process of the vertebral body bone of pathological changes and vertebral plates, row is decompression thoroughly.Two pairs of spinous process steel plates are contained in the spinous process both sides of vertebra up and down of the vertebral body bone of pathological changes, and with spinous process and the spinous process steel plate of spinous process steel plate screw by vertebral body, tighten the Luo medicated cap of spinous process steel plate screw, two pairs of spinous process steel plates are fastened on the spinous process of vertebral body of upper and lower of pathological changes vertebral body.Then, regulate the Luo bar with two and be placed on the side plate of spinous process steel plate bending, reach the gap that struts or compress pathological changes vertebral body position, tighten the Luo medicated cap on the corresponding adjusting Luo bar then by regulating the Luo medicated cap of adjusting on the Luo bar, two pairs of steel plates are fastening about making, and make whole spinal stabilization.
Again with breast
12The vertebra compression fracture is an example to retrodisplacement, the spinous process steel plate is regulated the holder erection sequence do concrete the introduction.In the operation with breast
12After vertebra resets, sting except that breast
12The spinous process of vertebra, vertebral plate reach goes up inferior articular process, the thoroughly decompression all around of row spinal cord.Last a pair of spinous process steel plate (2) and (1) are positioned on breast
11, breast
10, breast
9The both sides, the left and right sides of spinous process, and spinous process steel plate screw (3) passed spinous process steel plate (2) from left to right, spinous process, spinous process steel plate (1), fastening with the Luo medicated cap (4) of spinous process steel plate screw, breast altogether
11, breast
10, breast
9The Luo medicated cap of three screws.Go up a pair of spinous process steel plate like this breast
11,10,9Spinous process be fixed together, make their become as a whole.Same method, a pair of spinous process steel plate and screw Luo medicated cap are waist under using
1, waist
2, waist
3Spinous process tightens together, and makes them also become as a whole.Amount is gone the up and down distance of spinous process steel plate bending side plate then, will regulate the length of Luo bar (5) and reserve, and cuts unnecessary length part (this process can measure before operation X sheet set the tone save the length of Luo bar (5), quickening operation process).Regulating the Luo hole that Luo bar (5) passes the crooked side plate of spinous process steel plate (1) and (2), chew pincers or wrench with point, after the filing section in the nearly stage casing of Luo bar (5) is regulated in clamping, adjust the Luo medicated cap of regulating on the Luo bar (5) (6
(2)), bilateral is adjusted simultaneously, exempts to produce lateral bending, and making up and down, two pairs of spinous process steel plates strut suitable distance (can not be long, exempt to increase the weight of Spinal Cord).Reach the purpose that vertically reduces pressure up and down, can tighten the Luo medicated cap of regulating on the Luo bar (5) (6
(1)), make whole holder become a firm integral body, thereby make whole spinal stabilization.If adjust the Luo medicated cap of regulating on the Luo bar (5) (6 earlier
(1)), then make the vertebral body of pathological changes produce pressurization apart from shortening, tighten the Luo medicated cap of regulating on the Luo bar (5) (6 again
(2)), impel vertebral body to merge early, can be used as the usefulness of the fusion of vertebral body.
