Abstract
The utility model relates to a backbone reductor which is a medical appliance and is used for reducing operations for backbone fractures, dislocation and slide dislocation. The main structure of the reductor is that the reductor is provided with an upper and a lower clamp plates (1), (2) whose space is adjusted by set screws (7); the lower clamp plate (2) can move laterally corresponding to the upper clamp plate (1); the movement distance is adjusted by feed screws (8) and nuts (12) on one end of the lower clamp plate (2). The utility model has the advantages of reasonable structure and convenient use. Because the utility model doesn't need to leave in the body after the operation, and only two sections need to fix, the operation wound is reduced, and the patient can move conveniently after recovering.
Description
This utility model belongs to technical field of medical instruments, is a kind of when fracturing appears in the human spine, be used for the instrument of reattachment surgery when dislocation or slippage.
Resetting to the human spine is a kind of operation of more complicated, and the common operation method that adopts is: abdomen, restoring backbone are put in order in manpower Retracting repositioning or preceding road, but these methods all have the operation complexity, the bigger deficiency that waits of patient trauma.Adopt effect operating theater instruments preferably, as Ha Shi rod or Lu Shi rod, a very long time could take out because these apparatuses all need stay in the body, so very easily occur taking off collude, phenomenon such as disconnected rod, bigger to spinal injury, and the structure of using these apparatuses five above vertebras often is fixed together simultaneously, very inconvenience of the back patient activity that recovers from injury.
The purpose of this utility model is, designs a kind of restoring backbone device, and it is not stayed in the body, and reduces damage and operation wound to spinal column, and only fixing to two vertebras joints, strengthens the mobility after recovering.
Primary structure of the present utility model is, positor has last lower plate, and a connecting piece is housed between two clamping plate at least, and lower plate can laterally move with respect to train wheel bridge, and its displacement is by leading screw, nut adjustment.
The contrast accompanying drawing elaborates to structure of the present utility model:
Accompanying drawing 1 is a structural representation of the present utility model.(1) is train wheel bridge among the figure, (2) be lower plate, it is Cylinder (3) that two clamping plate, one end lumps together, and jackscrew (7) passes two clamping plate as connecting piece, and adjust distance between two clamping plate, lower plate (2) one ends have a leading screw (8), and it passes fixing head (4), and nut (12) is twisted thereon, lower plate (2) is equivalent to train wheel bridge (1) and can laterally moves, and its displacement is adjusted by nut (12) leading screw (8).During operation, punch at two intervertebral spaces earlier, in garden post (3) patchhole with positor one end, according to the operation needs, turn the spacing of nut (10), silk top (7) adjusting two clamping plate, two vertebras are drawn back, then by nut (12), leading screw (8), regulate the displacement of lower plate (2), the spinal column of dislocating is retracted.Behind the restoring backbone, two vertebras joint is fixed by steel plate, and positor takes out.(4) are fixing heads among the figure, are fixed on the train wheel bridge (1), in order to support leading screw (8).(10) be nut, (5) and (6) are packing rings.
The utility model is rational in infrastructure, and is easy to use, owing to need not stay in the body after its operation, and only need fix two vertebra joints, thereby reduced operation wound, patient recovers from injury rear Comparison of Gardening Activities conveniently.
Claims (4)
1, a kind of restoring backbone device that is used for spinal fracture, dislocation and slippage operation.It is characterized in that: it has train wheel bridge (1) and lower plate (2), has a connecting piece between two clamping plate at least, and an end of lower plate (2) is installed leading screw (8), nut (12), in order to regulate lower plate (2) with respect to the horizontal distance that moves of train wheel bridge (1).
2, according to the positor of claim 1, it is characterized in that: train wheel bridge (1) and lower plate (2) are when being fixed together, and the one end is Cylinder (3).
